Undirected fixed-discharging type blanking die

Abstract

The invention relates to an undirected fixed-discharging type blanking die which comprises an upper die base (1), a male die (2), a lower die base (3) and a female die (5). A die shank (8) is connected to the position of the center of the upper die base (1) and is connected with an external press, and the male die (2) is fixed under the upper die base (1) through a bolt and is positioned through at least two positioning pins; the female die (5) and a discharging plate (4) are fixedly sequentially mounted above the lower die base (3) from bottom to top, and a blanking hole (7) matched with the male die (2) is formed in the female die (5); a stop pin (6) is arranged on the rear side of the female die (4). The undirected fixed-discharging type blanking die has the advantages of simple structure and low requirements for operators; the male die and the upper die base are positioned through the double positioning pins therebetween, the female die and the discharging plate are fixed on the lower die base, the female die and the male die are matched accurately, blanking accuracy is high, the female die and the male die are less prone to damage, and maintenance cost of the die is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a non-guided fixed unloading type blanking mould. 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 the mold industry has also undergone tremendous changes. In addition to state-owned professional mold factories, collectives, joint ventures, sole proprietorships and private companies 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-...

AI Technical Summary

Problems solved by technology

[0004] The existing sheet metal stamping parts mainly use the mold to complete the processing of various shapes. The blanking mold is the most common type of mold in the cold stamping process. When blanking, the upper mold is pushed by a press to perform blanking. The structure of the material mold is complex, the operation technology level is high, and the matching precision of the die and the punch is difficult to control. Due to the excessive pressure, the material plate is easily damaged, the scrap rate of the blanking parts is high, and it is easy to cause the die and the punch to be damaged. The punch is severely worn and the maintenance cost is high
