Technical Field

The invention relates to the field of machining, in particular to a blank holder for a combined mechanical part.

Background

Machining refers to a process of changing the physical dimensions or properties of a workpiece by a mechanical device. The difference in the machining method can be divided into cutting machining and pressing machining. Traditional bordure adopts the punch press punching press to bordure, the mode of borduring obviously has the process loaded down with trivial details, the shortcoming that production efficiency is low, and the pressure of punching machine is great moreover, cause the damage to machine part easily, influence machine part's quality, the cohesion that often can appear the blank pressing after current bordure machining accomplishes moreover is not enough, later stage machine part drops, the effect of blank pressing also is not very good moreover, it is not thorough to have partial region blank pressing probably, leave the space, consequently need improve it.

Chinese patent is granted No. for CN 207872806U and is disclosed a combined machine part's blank holder device, the effectual of blank holder, do not easily drop deliberately, it is better to cross rotatory die cavity messenger battery pack blank holder effect, avoids the blank holder not in place to lead to battery pack to drop, carries out pressurize control to the device body through time relay, makes the battery pack blank holder inseparabler, and the work efficiency of blank holder is high moreover, and the blank holder quality is high. However, the device is not provided with a damping mechanism, so that the vibration generated during the operation of the device cannot be reduced, the service life of the device is influenced, and the conventional damping mechanism is arranged at the bottom of the device and is pressed by the gravity of the device for a long time, so that the service life of the device is influenced.
