XR: Reaction slide Once you're this deep in cooling, best to go all the way. Some applications, including those with a larger coil pitch, require an additional roll that guides the tube outward as the coil is being formed. The capability of modern machines, combined with the latest software and controls, shows just how precise tube bending has become. The downside, as with the rest of open loop cooling, is entirely the time requirement and cost increase. Many call tube bending a black art, a mysterious process with unavoidable trial and error. This part of the guide will be broken up into 2 parts. Certain tubes, especially those with thin walls, require a series of balls that can flex on the end of the mandrel, supporting the tube ID in the bend itself. XC: Clamping motion Written by Alex Banks ... Glass is a lot harder to bend than plastic or metal tubes, however. C: Bend angle This clamping die requirement can create challenges when you are forming a workpiece with short distances between bends, but special tooling can overcome this. The bend angle refers to the complementary angle of bend. Draw bending also requires a good tube with good welds. We've got a prepared length of tube, so now let's have a look at how to do the actual bends. Continue bending the tube until it reaches a suitable form. And on on that day, we hatched a plan. Another machine type is the two-roll, pinch-style roll bender. Consider the mandrel—its hardness matters. Next, grab the silicone insert and apply soap water to the entire insert. It may help to shape the tube around a fixed fulcrum, such as the point of your knee. YSFO: Follower pressure die motion. Moving onto the other type of … YM: Mandrel motion By using a 2F angled adapter fitting, you are eliminating the radius of the bend, and therefore it becomes possible to make bends without bending. Rigid Fitting O-Ring Replacement Pack. If the mandrel is moved too far forward, some of the balls actually may break off inside the tube during bending (see Figure 11). EK-Loop Soft Tube Cutter and EK-Loop Modulus Hard Tube Bending Tool, of which the first caters to builders preferring soft tubing allowing precise cuts of PVC, EPDM, Norprene, silicone or any other flexible tubing, while the second one is for builders preferring rigid (hard) tubing enabling them to bend their tubing without hassle and achieve exact angles. Water-Cooling with Hardline Tubing Guide: Borosilicate Glass. Getting Started. types of tube bending. So if a tube is bent to “45 degrees,” that’s 45 degrees complementary, or a 135-degree included bend angle (see Figure 2). The system clamps the workpiece just behind the rear tangent point. © 2021 FMA Communications, Inc. All rights reserved. Visit any muffler shop and you’ll probably see a ram-style bender (see Figure 3). Bend the tube into the desired shape a little at a time. Solid rubber extrusion for bending acrylic/PETG tubing. Check back soon for the rest of our California tour coverage. Some newer machines actually have space for tooling to combine bending processes. Regardless of whether you’re working with tube or pipe, and regardless of the bending process, making the perfect bend boils down to just four factors: the material, machine, tooling, and lubrication. Figure 3 16mm Tube Bending Kit,Bewinner 3pcs 16mm OD 45/90 /180 Degree Acrylic Hard Rigid Tube Bender Mould Tool Kit,Suitable for Water Cooling … Only 3 left in stock - order soon. 0.00.

Once complete, the tube will remain in its new shape permanently and is ready for cuts. Most tubes, though, are bent one of four ways: ram-type bending, roll bending, compression bending, or rotary draw bending. Enjoy full access to the digital edition of STAMPING Journal, which serves the metal stamping market with the latest technology advancements, best practices, and industry news. The system clamps the workpiece just behind the rear tangent point. Based on the size of tubing and the type of bend you need to make, you have several options for bending steel tubing from home. If you purchased a bending kit, locate the guide with the angle desired. If a workpiece has a one-diameter pitch and a large radius, the operator can lift the tube after one revolution to produce a continuous coil. Next, prepare the heat gun and stand it on its back (if possible) so that it is ready to use hands-free. In one complex application, for instance, the workpiece may be moved forward for the first bend (Y); the mandrel moved into position (YM), clamped (XC), and then bent (C, YB, YSFO). You generally can achieve a centerline radius (CLR) that’s three to four times the workpiece OD. Like any other manufacturing technology, the application requirements drive the fabrication method of choice. Subsequent bends may require the remaining unbent tube section to shift (X, Z). That's it. YB: Boost motion Home; Blog; Showcase; Products Waterblocks - CPU ... RTL Rigid Tube Bending Lubricant - 30ml. We moderate comments on a ~24~48 hour cycle. It's a bit of a trick if things are not in perfect alignment sometimes but for simple single angled bends, taking a short length of tubing and installing it in both fittings and using a square for 90 degree bends or angle finder is a good way to map things out. Other bending variables include the inside bend radius (sometimes called the intrados); the outside bend radius (or extrados); and the centerline radius or the neutral line, where neither compression nor stretching occurs. : Welding aluminum isn't as difficult as you might think, Paying tribute to my dad, Timothy Welton, by helping up-and-coming welders, How robots create manufacturing jobs and tax credits, Automated capabilities continue to bring greater efficiencies to manufacturing, Service center takes the plunge, becomes a fabricator almost overnight, Minibike enthusiasts make the most of miscellaneous metals, La manufactura esbelta en la era pandémica, Deje de calendarizar y empiece a priorizar, Ponga atención a los fundamentos en la prensa dobladora, 5 consejos para aumentar el rendimiento de la soldadura, Additive Report Advisor: The truth about 3D printing in metal fabrication, NIST awards $4 million to universities to study measuring methods for additively manufactured parts, General Motors opens a new facility dedicated to 3D printing, Achieving success with rotary draw bending, Getting the most for your tube bending buck, Steel Hedging 101: Introduction to Managing Price Risk, Steel 101: Introduction to Steel Making & Market Fundamentals, The FABRICATOR's Technology Summit & Tours. Details: Outer Diameter: 10mm; Length 500mm; For use with all 10mm ID Acrylic/PETG Tubing ** NOTE" Silicon bend chord can shrink by nearly 4% with drops in the temperature from 35C to 15C. All rights reserved. Regarding the wiper die, its position is critical (see Figure 10). One is a traditional clamp die used for holding straight sections, and the other—called a form die—is machined to a specific shape so it can clamp to previously formed bends. The roller effectively “compresses” the tube against the central bend die. Die Science: Finding the root cause of stamping failures, Ask the Stamping Expert: How to start using tool coatings, Engineering Angle: Draw bead restraining forces in sheet metal drawing operations, Aluminum Etc. Rigid water cooling tubing comes in a variety of sizes and materials, providing many options in its appearance. A CNC machining center may have five axes. Whilst it's definitely one of the most intensive ways to plan a water-cooling loop, I find it offers a huge amount of flexibility that more traditional methods simply can't hope to match. Fabricators & Manufacturers Association, Intl. If you have a hard workpiece, you need a soft mandrel; if you have a soft workpiece, you need to use a hard mandrel. Take a look at that below: The basics are trivial; you need these items: Hard tubes of choice. Such a tight fit would cause significant friction without the right lubrication. B: Plane of bend rotation Copyright © 2021 GamersNexus, LLC. Editorial: Steve “Lelldorianx” Burke Video: Andrew “ColossalCake” Coleman, Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. Make sure the diameter matches the tube diameter, though. The condition of the wiper die’s contact point is also critical. The die should be angled slightly (a little off parallel with the tube) so that its end contacts the tube just before the inside radius tangent point—a transition that’s the workpiece’s weakest point during bending. The soap will prevent evaporation of the water while in the tube, which is important for ensuring easy removal once the bend is complete. Z: Vertical shift of the workpiece PC water-cooling project part two: Cut tubes, not corners Now that we have everything ordered and ready to go for our big PC water-cooling project, we … Which rolls move where depends on the machine. In this arrangement, you have a stack of two or three (or even more) clamp dies. We've got Part 1 of our Sean Tracy interview (Technical Director of Star Citizen) going live tomorrow, alongside some MSI laptop coverage. First world problems. This would work ($30). For instance, say you have a part that has several tight-radii bends as well as one large-radius bend. Liquid cooling has become infinitely more accessible with plug-and-play AIO solutions, but those lack some of the efficacy and all of the aesthetics. For this system, the tube feeds between an upper and lower roll, while on either side two adjustable guides move to produce the desired bend angle. It can be purchased as simple straight runs for the user to bend or assemble with, or already bent to preset angles. Thermaltake Pacific DIY OD 16mm (5/8") x ID 12mm (1/2") Water Cooling PETG Hard Tube Bending Kit and Thermaltake Pacific V-Tubler PETG Hard Tubing 5.0 out of 5 stars 3 84.28 $ 84 . More specifically, it’s the distance between two tangent points, where a straight section begins to curve and the bend starts or finishes. Building a bend die that large for rotary draw bending wouldn’t be practical. Ram bending is one of the oldest, simplest, and least expensive A project may require bending steel tubing for any number of reasons. Place this in front of you. To accommodate for radial growth, particularly if it involves hard material and a 3×D CLR or greater, you may need to use a bend die with a smaller radius. It's ideal to use some sort of guide for this, e.g. Even with hard tubing, which has the advantage over soft tubing, you are restricted to a certain radius of bending. If you have a hard tube and a hard mandrel, or a soft tube and soft mandrel, the mandrel will tend to stick inside the tube and wreak havoc on the process. If there's one trend that's completely taken off in custom water-cooling in the last few years, it's hardline tubing. But it is not as controllable You do not have to worry about the bend losing its shape. Hard tubes are less likely to slip off of their mounting barbs with age or transport (fluid between the tube and its mounting point can lubricate the tube, causing a slip and slow leakage). Commonly used for large workpieces in construction, roll bending generally entails three rolls positioned in a pyramid, oriented either vertically or, for larger sections, horizontally. This shouldn't take long, with a decent amount of heat. We might soon be building a wet bench for open loop liquid cooling, as we're starting to receive GPUs with water blocks for testing. Wiper dies also need to be kept properly lubricated at the contact point to prevent premature wear. Today, we've got a brief hard tube bending tutorial with Thermaltake's Thermal Mike to lead us into our future open loop content. 59 Designed for ID 1/2” (12mm) x OD 5/8” (16mm) hard tube, the Pacific Hard Tube Bender Kit allows makers to construct aesthetically superior water cooling systems by allocating the tubes and radiators to each particular component and incorporating externally-modular upgrades into their chassis. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. This variation should be accounted for, especially for bending processes using precise, tight-fitting tooling on small bend radii. This method is most common in symmetrical workpieces—those with identical bends on either side—often bent in one setup on a machine with two bending heads. A mandrel with articulating balls fits tightly within the tube ID. Also, every pipe schedule has a nominal wall thickness. It should be sharp to the touch. Many use roll bending to produce spirals. Enjoy full access to the digital edition of The Additive Report to learn how to use additive manufacturing technology to increase operational efficiency and improve the bottom line. $59.99. It felt like filming a cooking show, at times. Pipe, usually used to transport fluid or air, is specified by its nominal pipe size (see Figure 1). The shorter the clamp is, the more pressure it puts on a short section of the workpiece, thus increasing the risk of deforming it. Occasionally some technicians shorten this length to two times the tube OD, but this isn’t usually recommended. Other critical dimensions Specialty tube bending processes abound, some old and some new. $29.99. Insert the heated tube into the PETG Easy Bending Tool 4. There will be some delay after submitting a comment. Some of the most common axes are: Y: Distance between bends If radial growth is excessive, the nature of the rotary draw process means that after the clamp die releases, the radius at the beginning of the bend will be noticeably different from the radius at the end of the bend. Often supplied as a paste or gel, they can be diluted to whatever consistency the application requires. In tube bending, the quality, size, and consistency of that weld seam matter. 0.00. You'll want about 10-20% of the glass to be soap – nothing too crazy. As always, you should use information from your machinery and material suppliers to determine application-specific requirements. 2135 Point Blvd., Elgin, IL 60123 (815) 399-8700. If the two edges of the joint don’t align perfectly, or if the weld bead is too large or inconsistent, these discontinuities will affect the tube’s roundness. True, material variability and certain application-specific challenges make some level of unpredictability unavoidable. Figure 2 Taking shape with hard tubes for PC water cooling Harder (or rigid) tubing like glass , acrylic , carbon and the more popular PETG offer the possibility to create some stellar-looking systems. Easily access valuable industry resources now with full access to the digital edition of The FABRICATOR. Generally speaking, the harder the tube and the smaller the bend’s centerline radius, the greater the springback and resulting radial growth. From experience, I fully reco… This involves heating the tubing until it's reached its glass-transition temperature. Soft tubing is more easily manipulated and is as “plug and play” as it gets with an open loop, though “plug and play” isn't really desirable with open loops. On some, the top roll moves up and down to produce the desired angle; on others, the two bottom rolls move and the top roll remains stationary (see Figure 5). Rotary draw bending supports the flow of the material during bending using a mandrel in the tube ID and precision tooling on the outside (see Figure 8). The rolls move to produce specific, usually very large radii. All these elements effectively control both the tube ID and OD throughout bending. Open loop liquid cooling is done with either soft tubing or hard tubing, the latter of which must be heated (with a heat gun) to make necessary bends within the system. You need to use one rated the same size as the internal diameter of your tubing. To achieve the perfect bend, you need a good tooling setup, and nowhere is this more critical than in rotary draw bending. It makes sense really, you use the silicone insert to stop the tube from kinking or collapsing, but the more bends you put it through, the more tension there is when you try and pull it out again. Compression bending uses a roller or compression die (sometimes called a follow block) to bend the workpiece around a stationary bend die (Figure 6). As a rule of thumb, make sure you have a combination of hard and soft material. This method is popular in square tubing applications, for which many design the ram tool so that it deliberately compresses and slightly deforms the inside bend radius (see Figure 4). The roller effectively “compresses” the tube against the central bend die. To bend hard tubing, the tube must be made malleable – done with heat – and must also keep the full internal diameter so that flow is not kinked. Nevertheless, with the right material, tooling, lubrication, and machine, you have a much better chance of achieving the perfect bend—every time. It made sense to just leave it as 'Gamers.'". GamersNexus.net is Owned, Operated, & Maintained by GamersNexus, LLC. That’s because as the outside stretches, the inside radius compresses and at a certain point starts to wrinkle. 16mm Tube Bending Kit,Bewinner 3pcs 16mm OD 45/90 /180 Degree Acrylic Hard Rigid Tube Bender Mould Tool Kit,Suitable for Water Cooling System (Black16mm) Thermaltake Pacific DIY OD 16mm (5/8") x ID 12mm (1/2") Water Cooling PETG Hard Tube Bending Kit CL-W093-AL00BL-A An inconsistent weld bead protruding into the tube’s inside or outside surface will wreak havoc on the mandrel, pressure die, and wiper die. Some ovality is acceptable for certain applications, but unacceptable for precision work. That creates problems if you want to create the perfect bend. One of the oldest and simplest tube bending methods, it uses a hydraulically driven ram that forces a tube against rollers or pivot blocks. Acrylic needs to be heated for longer periods of time over a bigger surface compared to PETG, which makes it less popular with first-time hard-tube builders. It’s not recommended for workpieces with a CLR less than three times the tube diameter. The bend’s outside surface may flatten slightly because the tube ID is not supported. If workpiece cosmetics are important or the application has tight bending tolerances, the ram-type method may not be the best choice.
