Tube End Forming Guide

For tube end forming devices, tube end forming tools are made that can control tube end size and shape for different applications. The simple end forming techniques are segmented tool measuring, stamping shape, rotary forming, roll forming and rotating. When choosing a tube end forming process, it is necessary to understand whether the tube needs to be made, if the object is part of the assembly of the part and if the mating part needs to be modified. Therefore it is important to consider whether the tube can be modified for the amount of deformation needed.The best way to use this material, if so, is to achieve the final form while preserving acceptable tolerances and standards for appearance.

Tube End Forming Categories

End reduction

End reduction is a tube end forming process of reducing the outer diameter (OD) of the tube. This is achieved to make the inner diameter (ID) of the same tube match the reduced end. By using common segmentation methods, these types of machines can minimize tubing. The tube size can be minimized by using segmented jaws and fixed cones on the outside of the tube.

End expansion

The tube end forming process called end expansion is mainly carried out using horizontal pneumatic and hydraulic end forming equipment, which is adjusted by technicians according to application requirements. These types of tube end forming machines can expand the tube by using segmented fingers and tapered mandrels inside the tube.

Ram Forming

Ram forming is done by sequential vice and slider action to perform journal expansion and ring reduction as well as expansion and contraction with segment tools. The vice and punch molding includes a vice to grip the tube while the slider presses the cork into the tube or a ring on it to get the finished size. These machines may be adapted to use segmented fingers to expand or jaws to shrink. These tube end forming machines can also use piston forming tools (vice, jaws and slider tool) for flaring, shrinking, grooving, flaring etc. Directly at the end of the tubing, the flange forms an edge or flange. Cold or heated tubing may be used to make the collar. To build a symmetrical, sloped edge, a chamber is used to cut a rectangular edge or corner. Usually, the minor incisions are at a 45 ° angle.

Roll Beading

The tube end forming method of beading the end of a cylindrical metal tube to shape a spout-like form is called roll beading. This application is suitable to improve the outline of the rolled metal mold.

Rotary Forming

Flared tube ends and hose ends are usually created by the rotary tube end forming process. A basic benefit of this method is that it can be used to operate around a tube's circumference, especially where sharp angles and radical diameter adjustments require more subtle work on the tube.

Understanding Your Tube End Forming Requirements

Manufacturers that need to perform tube end forming processes ask several of the same queries, whether a component or a set of components is the style. What does the tube that is shaped have to do? Are all the component functions needed? Does it already have a particular molding process in the new design? May we make improvements to the pieces that match? With fewer pieces, may I achieve the same result? In the component design and shaping procedure, tube alloy and manufacturing process are essential considerations. Will the material withstand the deformation necessary during the tube end forming process? If so, what is the best way to work to achieve its final shape with the material? Is the tubing smooth or does it have a seam for welding? What are the imprint-specific tolerances and aesthetic requirements?

To maximize the final tube end forming process, knowing the assumptions behind your team design is important. The part design for an automobile exhaust component, for example, could be based on a complex assembly process that results in a two-piece welded assembly. The configuration of the component can be altered by concentrating exclusively on the product and aesthetic criteria, leading to an improvement in the molding process and a substantial reduction in cost.

The unit cost of a project, which usually involves tooling costs, repeatability, cycle time, set-up time, and the ability to adapt the procedure to meet material adjustments, can be calculated after tube end forming methods have been defined to allow the finished part to be formed to consumer requirements.
