Multistation feeding device of punching machine

Abstract

The invention relates to a multistation feeding device of a punching machine, comprising a support connected with a working face of the punching machine, wherein two feeding arms are arranged on the support and below a position corresponding to the position of a punch head of the punching machine; the two feeding arms are respectively provided with a group of feeding claws for clamping punching pieces and respectively connected with two feeding slide blocks arranged at the upper part of a face at one side of the working face; the feeding slide blocks are connected with a front and back moving mechanism, a left and right moving mechanism and an upper and lower moving mechanism; and the three moving mechanisms are provided with three eccentric wheels connected with the same main shaft. The multistation punching work of the punching pieces is finished automatically on the same punching machine in a mechanical way, therefore, labor is saved, the production efficiency is increased, and the safety in use is improved; and a driving shaft led out of the punching machine is linked with the feeding device to work, thus, an additional driving power is not needed, the whole multistation feeding device is of a mechanical structure and stable in performance, equipment is durable, and the cost is greatly reduced as comparison with that of an automatic punching machine controlled through a program.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a feeding device, in particular to a multi-station feeding device for a punching machine. Background technique [0002] When punching a workpiece with a punching machine, a workpiece often needs to be punched several times on different molds to complete. For the workpiece that has been punched several times in the current ordinary punching machine, it is necessary to manually take out and load the material every time it is punched, and then put it on another punching machine. The second stamping is carried out on the upper part, and the processing of the workpiece can only be completed after several times of manual retrieving and loading, which requires many times of repeated loading and unloading, which is time-consuming and labor-intensive, which increases the production cost, and manual operation is prone to safety hazards. There are also multi-station punching machines at pres...

[0002] When punching a workpiece with a punching machine, a workpiece often needs to be punched several times on different molds to complete. For the workpiece that has been punched several times in the current ordinary punching machine, it is necessary to manually take out and load the material every time it is punched, and then put it on another punching machine. Carry out the second stamping on the top, and so on, the processing of the workpiece can only be completed after several times of manual loading and unloading, which requires many times of repeated loading and unloading, which is time-consuming and labor-intensive, increasing the production cost, and manual operation is prone to safety hazards

At present, there are also multi-station punching machines, but this kind of punching machine needs program to control the feeding action, the equipment is complicated, the cost is too high, and it is difficult to popularize and promote.
