The die holder is large in size, integral machining is difficult, and time is wasted, so that the die holder is divided into the upper clamping die and the lower clamping die, the upper clamping die and the lower clamping die can be machined simultaneously, machining and manufacturing difficulty is reduced, and machining and manufacturing time is saved.

The utility model discloses further preferred scheme: the die holder is provided with a limiting column for connecting and fixing the upper clamping die and the lower clamping die.

The utility model discloses further preferred scheme: the push rod component further comprises a push rod fixing seat, and the push rod body is connected with the push rod fixing seat. The fixing seat is used for connecting an actuating element such as a hydraulic cylinder, and the actuating element provides power for the ejector rod body.

Compared with the prior art, the utility model has the advantages of simple structure, spare part are few, convenient assembling, can carry out bulging processing with the pipe surface for the bumper shock absorber. Briefly, the lumen that sets up is used for filling in and treats the processing pipe fitting, the ring groove in the lumen is used for the pipe fitting surface to rise the drum shaping, the fender wall that sets up is used for the restriction to treat the motion of processing the pipe fitting, the pipe fitting is filled in the lumen after, its right-hand member supports on keeping off the wall, ejector pin body inserts the pipe cavity back and applys right effort to treating the processing pipe fitting, owing to keep off the setting of wall, the pipe fitting is unable to be removed, the pipe fitting is because of receiving the extrusion, its surface material is impressed in the ring groove, the surface of pipe fitting realizes.

The technical personnel packs in the pipe cavity and waits the pipe fitting of processing into, supports the pipe fitting right-hand member on keeping off the wall, then is connected ejector pin body and power component (hydraulic cylinder) to insert the ejector pin in the pipe cavity, finally exert the effort to the pipe fitting by the ejector pin body, under the effort of ejector pin body and the counter force who keeps off the wall, the pipe fitting is because of receiving the extrusion, its surface material is impressed in the ring groove, realizes the bulging on pipe fitting surface.
