Punching die quick pulling type die capable of selecting or not selecting to conduct trimming

Abstract

The invention discloses a punching die quick pulling type die capable of selecting or not selecting to conduct trimming. The punching die quick pulling type die comprises a first shell and a second shell, wherein the first shell is provided with punching male die bodies, and the second shell is internally provided with a trimming mechanism. The bottom ends of the punching male die bodies make contact with the trimming mechanism through a material guide mechanism. The material guide mechanism comprises a first material guide system and a second material guide system which are symmetrically arranged on the inner side walls of the two sides of the first shell. The trimming mechanism is arrange in the lower position between the first material guide system and the second material guide system. The first shell and the second shell are each of a semi-open structure with one side provided with an opening. According to the punching die quick pulling type die capable of selecting or not selecting to conduct trimming, trimming or no trimming can be selected through embedding or pulling of the quick pulling device, operation is easy, the flexibility is high, and the using limitation is greatly reduced; in addition, the work state of punching and operation of the whole set of die cannot be influenced when only switching between trimming or no trimming is conducted; and the stability performance is high, the working efficiency is high, the industrialization cost is low, and improving of the economic benefits is facilitated.

Description

technical field [0001] The invention relates to the technical field of punching and trimming dies, in particular to a quick-drawing die for selecting whether to trim or not to trim. Background technique [0002] In order to realize the integrated operation of punching and edge trimming, the two processes of punching and edge trimming can usually be completed in a pair of molds, which is convenient to simplify the process and save costs. However, the existing punching and edge trimming molds must be Go through the two processes of punching and edge trimming, that is to say, after the workpiece is punched, edge trimming must be carried out. It is impossible to choose whether to trim the edge or not according to the actual situation. The flexibility is poor, and it is difficult to realize single punching and edge trimming. The switching of one process or two processes has great limitations. [0003] Moreover, the punching and edge trimming mechanism in the existing punching an...

[0002] In order to realize the integrated operation of punching and edge trimming, the two processes of punching and edge trimming can usually be completed in a pair of molds, which is convenient to simplify the process and save costs. However, the existing punching and edge trimming molds must be Go through the two processes of punching and edge trimming, that is to say, after the workpiece is punched, edge trimming must be carried out. It is impossible to choose whether to trim the edge or not according to the actual situation. The flexibility is poor, and it is difficult to realize single punching and edge trimming. Switching between one process or two processes, the use of large limitations

[0003] Moreover, the punching and edge trimming mechanism in the existing punching and edge trimming dies are mutually affected, that is, if the edge trimming mechanism breaks down, it will cause the punching operation to be implicated, and even the running state of the entire set of molds will be affected. The stability performance is low, and the formed workpiece needs to be ejected before being clamped and blanked. The labor load is large, the work efficiency is low, and it is difficult to meet the stamping operation of a large number of workpieces. The industrialization cost is high and the economic benefit is poor.
