Like in press brake forming, tubes experience springback after bending, producing a bend that undergoes radial growth. All these elements effectively control both the tube ID and OD throughout bending. Specialty tube bending processes abound, some old and some new. © 2021 FMA Communications, Inc. All rights reserved. The pressure die (also called a pressure slide) supports the outside radius during bending. 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 … Fabricators & Manufacturers Association, Intl. Heat the tube at the bend point, using a heat gun or hair dryer (not supplied) 3. Z: Vertical shift of the workpiece Pipe, usually used to transport fluid or air, is specified by its nominal pipe size (see Figure 1). 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. Visit any muffler shop and you’ll probably see a ram-style bender (see Figure 3). 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. You will want to bend from one side only while ensuring the tubing is supported wile bending. The capability of modern machines, combined with the latest software and controls, shows just how precise tube bending has become. Rigid water cooling tubing comes in a variety of sizes and materials, providing many options in its appearance. From experience, I fully reco… Easily access valuable industry resources now with full access to the digital edition of The Fabricator en Español. The trick here when doing complicated bends is to stop between bends, pull out the insert and work on each section one piece at a time. 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. Easily access valuable industry resources now with full access to the digital edition of The FABRICATOR. Most tubes, though, are bent one of four ways: ram-type bending, roll bending, compression bending, or rotary draw bending. This process is by far the least expensive way to bend tube and pipe, but it’s not as controllable as other methods. GamersNexus.net is Owned, Operated, & Maintained by GamersNexus, LLC. If you see a towel bar with two identical bends on each side, it was probably formed with compression bending (see Figure 7). Building a bend die that large for rotary draw bending wouldn’t be practical. 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 A heat gun capable of getting the tubes into a malleable state. Heavy Duty Hose Cutter (0-25mm) 1.00. Easily access valuable industry resources now with full access to the digital edition of The Tube & Pipe Journal. Time: About 5 minutes. Figure 1 To achieve the perfect bend, you need a good tooling setup, and nowhere is this more critical than in rotary draw bending. It felt like filming a cooking show, at times. Written by Alex Banks ... Glass is a lot harder to bend than plastic or metal tubes, however. 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). Pipe is specified by its nominal pipe size, while tube is specified If you purchased a bending kit, locate the guide with the angle desired. types of tube bending. It made sense to just leave it as 'Gamers.'". 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. $59.99. 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. 59 A project may require bending steel tubing for any number of reasons. The tube will feel malleable soon, at which point you should disable the heat gun, place it to the side in a safe fashion (standing up, so that any residual heat on the surface doesn't burn you or nearby elements), and quickly bend the tube in the shape desired. XSPC - Performance PC Water Cooling. Next, prepare the heat gun and stand it on its back (if possible) so that it is ready to use hands-free. But in reality, the basic principles have remained the same for decades. So if a tube is bent to “45 degrees,” that’s 45 degrees complementary, or a 135-degree included bend angle (see Figure 2). 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. That creates problems if you want to create the perfect bend. 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). Moving onto the other type of … Next, grab the silicone insert and apply soap water to the entire insert. Hold for about 20 seconds, then test to see if the tube has hardened. 2135 Point Blvd., Elgin, IL 60123 (815) 399-8700. 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. 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. But when you’re specifying a bending machine, the centerline radius, the outside diameter, and wall thickness are critical variables. It’s then unclamped (C), and moved again into position (Y). 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. 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. We've got a prepared length of tube, so now let's have a look at how to do the actual bends. 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. It's ideal to use some sort of guide for this, e.g. As for the clamping die, its length should be three times the tube diameter. Thermaltake Pacific DIY OD 16mm (5/8") x ID 12mm (1/2") Water Cooling PETG Hard Tube Bending Kit CL-W093-AL00BL-A 4.7 out of 5 stars 570. Granted, compared to the rest of the loop, hard tubing cost can start to feel negligible. You may want to practice with some cheap amluminum conduit to get the hang of it. That’s why some machines offer roll bending along with rotary draw bending in one unit. Today, we've got a brief hard tube bending tutorial with Thermaltake's Thermal Mike to lead us into our future open loop content. For rotary draw bending, more all-electric machines are finding homes on tube shop floors. PETG Somewhat frowned upon by hardcore enthusiasts and overclockers, PETG is an awesome choice for beginners due to being way easier to heat up and bend than Acrylic. C: Bend angle The first part will focus on the cutting and preparation of the tube. We had a chance to stop over at Thermaltake's offices while making the City of Industry circuit last week, and used some of that time to film a brief tutorial on hard tube bending. Easily access valuable industry resources now with full access to the digital edition of The WELDER. (These advanced systems also can have stacks of bending dies for different tube radii, so an operator need not change out tooling between different jobs.). Place this off to the side.
