Stable multi-stage buffer punching device

Abstract

The invention discloses a stable multi-stage buffer punching device. The stable multi-stage buffer punching device comprises a punch and a knife rest used for supporting the punch. The knife rest is horizontally arranged. A knife rest base is arranged below the knife rest and connected with the knife rest through a knife rest elevating device. The knife rest comprises a main rotating shaft, a first auxiliary rotating shaft and a second auxiliary rotating shaft. The upper part of the main rotating shaft and the upper part of the second auxiliary rotating shaft are respectively and fixedly provided with a driving sprocket wheel and a second driven sprocket wheel in a sleeving manner. The upper part of the first auxiliary rotating shaft, the driving sprocket wheel and the second driven sprocket wheel are correspondingly and fixedly equipped with first driven sprocket wheels in a sleeving manner. The lower part of the second auxiliary rotating shaft is connected with the punch. The lower part of the first auxiliary rotating shaft is connected with the knife rest elevating device. Compared with the prior art, the technical scheme is ingenious in structure, easy in operation, good in application effect and long in service lifetime. The height and rotary angles of the punch are adjusted in order to meet requirements for hole depths and angles of inclinations of to-be-machined spare and accessory parts. Therefore, machining precision of the spare and accessory parts is effectively enhanced.

Description

technical field [0001] The invention relates to punching equipment, in particular to a stable multi-stage buffer punching device. Background technique [0002] In today's product production and processing process, more and more products require a series of punching processes. The punching machine used to process spare parts is equipped with pliers to hold and move the processed parts on the surface of the table. spare parts. These pliers are mounted on a horizontally indexed datum bar in such a way that the position of these pliers is determined according to the size of the machined parts and to suit different needs, and during the punching operation, carried on the machine tool Punches will not interfere with these pliers. [0003] The indexing rod can be moved in two dimensions on the working plane of the punch so that the plate, still held by the pliers, is presented to the mechanical tool carried by the punch, so that it is possible to execute the command and control o...
