Description

Punch die holder for forming tube ends of bulb tubes

Technical Field

The utility model relates to a punch die holder for forming a tube end of a bulb tube.

Background

The connection between the punch and the die holder in the current 'bulb tube end forming' processing adopts bolt fastening. In the production and processing process, in order to ensure that the punch and the cover plate are connected together, the mode that the punch is connected with the die holder through bolts and then the cover plate is used for pressing the die holder is adopted. When the punch is in stripping action, the bulb tube can apply wrapping force to the punch, and the punch is connected with the cover plate by means of locking force of the bolt when the punch is in stripping. In the production and processing, the risk that can take place to fracture after the fastening bolt of drift uses a certain number of times to lead to the drift to stay inside the bulb when the drawing of patterns, part of bolt also can fracture inside the drift simultaneously, need get rid of the inside broken bolt of drift and change new bolt side and can continue to put into production the use.

In summary, the conventional punch die holder has the following disadvantages: 1. the risk of bolt breakage exists after long-term use; 2. after fracture, the punch and part of bolts can remain in the bulb, the punch is required to be taken out from the bulb, the residual bolts are removed, then the bolts are fixed by new bolts to continue production, and maintenance is very complex.
