Cold push elbow machine

Cold push elbow machine

The forming process of cold extrusion elbow: the special cold pushing elbow machine is used to put the tube billet into the outer die. After the upper and lower die is closed, the tube billet moves along the reserved gap between the inner die and the outer die to complete the forming process under the push rod.It is made of a horn core head or mandrel into the mold, the pipe fittings into the mold, the mold should have two semicircle arcs, up and down one each, in the push process is a process along the mandrel bending.There is a support behind the cutting pipe section into the mandrel, behind a arch frame will be firm mandrel.There is a hydraulic rod jacking device in the center, which pushes forward through the hydraulic transmission top column.

In the process of pushing, the wall thickness should not change under the normal environment, but if it is due to the reasons of things, some places will produce signs of wall reduction, as is usually the same, the wall thickness should be added with some allowance, to prevent in pushing due to local thickness reduction and out of tolerance.

The elbow made by the cold extrusion process of the inner and outer die has elegant shape, uniform wall thickness and small size faults. Therefore, the stainless steel elbow is especially thin wall stainless steel elbow forming and more than accept the cold push elbow machine.The precision of the inner and outer die used by this process is high.The requirement of the wall thickness of the billet is also strict.
