There are some necessary components For Mandrel Bends
The mandrel, which is the key component of tooling, that is the key part provides support to the inside of the tube. Its primary function is to prevent the tube from buckling and necking, and there are many different variations of mandrels exist.
The bend die is the primary tool forming the tube to produce the desired bend radius. This is the form against which the tube is clamped and then drawn around to produce the bend. The essential specifications of a bend die are the outside diameter and the bend radius of the tube to be bent.
The wiper die keeps the tube from wrinkling during the bending process. A wiper die is very important if the tube’s resistance to compression is high.
A clamp die which is an important part, that is the part makes good bending or bad bending, it clamps the tubing material against the bend die as it rotates to form the bend. There are two specifications of primary importance in a clamp die, Length and cavity texture, which are related to each other. If the clamp is short, then the cavity surface will be rough because it must be to maintain the force of the grip on the tube. Serrations, knurling, and carbide impregnation roughen the cavity surface which improves the clamp die’s grip upon the tube.
Infengde accept custom design metal parts and also can assist customers on making engineering drawings. We can make samples for approval before mass production of mandrel bending products.
