Some quite elaborate shapes can be produced. In general, CNC bending is bending made more productive and efficient by using automation. To produce more complex multi-bend components, for small diameter tube where it is possible to bend it manually, hand bending jigs use compression bending. Then the machine performs those operations automatically.ĬNC controlled tube bending machines usually use a combination of presses and rollers to guide the tubes and pipes along the process.
#SMALL DIAMETER TUBE BENDING SOFTWARE#
The operator uses the programming software to feed the data of the operation or operations required. Common CNC machines include lathes, drills and other machining tools. It is a term frequently used in manufacturing to describe machines that work with a programming software to perform their operations. This is possible because of CNC bending machines.ĬNC stands for Computer Numerically Controlled. Today, most bending only needs human assistance, not constant guidance. At the same time, a wide range of pipe sizes fit the same machine and a large variety of bend angles are available.Īpplications: large industrial structural parts, short radius bends, heating system parts, thick-walled parts, etc. It is an accurate method that does not require mandrels. Applying the pressure to a hot workpiece allows for energy-efficient bending. At the bending point, there is an induction coil. With induction bending, a profile is drawn through a die. The mandrel’s objective is keeping the tube from collapsing. Bending a small radius, thin tubes or harder materials can result in an unsatisfactory outcome. In bending steel and aluminium tubes, a mandrel is necessary for more difficult jobs. Thus, adding a wiper die just after the bend die helps to smooth the surface. It may result in wrinkles with large deformations. The purpose is to avoid the formation of any humps on the inside radius.ĭuring the forming process, the material turns plastic during bending. Wiper DieĪ wiper die places just after the bend die. The pressure die makes sure the tube follows the bend die’s contour. Its main purpose is to prevent the pipe from slipping. The clamp die presses the tube onto the bend die. The selection of die is very important, as the tube’s inside radius depends on it. The tube clamps to the bend die and the drawing process produces the necessary bend. Chaffee Memorial Blvd., Wyoming, MI 49548, 61, fax: 61, bend die, also known as the bend form or the radius die, is the most important part of a rotary-draw bending machine. Schwarze-Robitec America Inc., 3566 Roger B. No bolts are required to fasten the freely stored bend former to the turntable, which increases repeatability and process security. Tension bars are easily opened and closed for tool changing. Quick-Tool-Unlock ensures faster refitting times with a rapid clamping system for the bend former. This reduces production time by 20% to 40% depending on component and tube geometry. A vertically adjustable pressure die moves to the individual levels in sync with the tube.įor each bending sequence, the NxG control system assesses the interaction between all axes, operating them simultaneously and preparing the next sequences. Despite its multistack bending tool, the machine is able to cut tubes as well because of its extended vertical transport carriage. Depending on tube system, the controls increase output up to 50% due to simultaneous operation of the axes.īy combining the bending and cutting processes for 3-in-diameter tubes, the CNC 80 E TB MR shortens turnover times and reduces waste by up to a 90%. Because the electric controls are integrated into the machine’s body, the tube bender doesn’t require an external control cabinet and can therefore be easily moved around the production area if necessary. Thanks to intelligent scanners and a slim machine bonnet, the machine can be operated without safety fences. Like all Schwarze-Robitec machines, the bending table and bend former can be operated independently, simplifying the entire process. Tubes with complex geometries can thus be bent in one step. It’s available in left/right bending versions and a version with a bending head that rotates 180 degrees. The fully electric machine bends steel tubes up to 1 in in diameter and wall thicknesses of 0.08 in as well as stainless steel tubes up to 0.8 in in diameter and wall thicknesses of 0.06 in. (Wyoming, MI) CNC 25 E TB MR with integrated NxG control that it’s adding the control system to two more machines.
