Abstract

The invention discloses a non-guide punching die. The non-guide punching die comprises an upper die part and a lower die part. The upper die part comprises a die handle, a punch and a female die. The die handle is connected with an external press, the punch is fixed to the bottom of the die handle, and the female die is fixed to the punch. The lower die part comprises a die base, a male die and an unloading plate, the male die is fixed to the die base, the male die is sleeved with the unloading plate through an unloading screw, one end of the unloading screw is fixed to the unloading plate, and the other end of the unloading screw is fixed to the die base. The punching die is of an inverted structure, a positioning device can be installed on the male die, and therefore the punching direction and positioning precision can be guaranteed. The die is free of guide die frame interference, and the appearance size of a punched part and the punching position are not limited by the die.

Description

technical field [0001] The invention relates to a punching die, in particular to a non-guided punching die. Background technique [0002] Since the reform and opening up, with the rapid development of the national economy, the market demand for molds has continued to grow. In recent years, the mold industry has been developing rapidly at a growth rate of about 15%, and the ownership of mold industry enterprises has also undergone tremendous changes. In addition to state-owned professional mold factories, collectives, joint ventures, sole proprietorships and private enterprises have also developed rapidly. In recent years, many mold companies have increased investment in technological progress, and regard technological progress as an important driving force for enterprise development. Some domestic mold companies have popularized two-dimensional CAD, and have begun to use international general software such as UG, Pro / Engineer, I-DEAS, and Euclid-IS. [0003] Mold is one of...
