Automatic material feeding and discharging structure of punching machine for punching cover plate of iron wine box

Abstract

The invention discloses an automatic material feeding and discharging structure of a punching machine for punching a cover plate of an iron wine box. The structure comprises a rack on which a working table is erected, wherein the working table is provided with a die holder and a punch, a material feeding frame is erected at the front end of the working table and is installed on a guide rail of a support through a guide slot, supporting cushion blocks are distributed on the material feeding frame, an overturning clamp support is arranged on the material feeding frame and comprises a fixed plate on which a fixed seat is installed through a regulating slot, a rotary shaft is rotatably installed on the fixed seat and is fixedly provided with a clamp plate, and the fixed plate is slidably installed on a guide rod through a guide sleeve; and a placing cavity is arranged in the middle of the die holder, air vents are distributed in the placing cavity, a die body outside the placing cavity is provided with an annular limit boss matched with an end cover, and magnetic sheets are fixedly arranged in a concave cavity at the inner side of an annular groove. According to the invention, all-around punching of plate materials is realized, during the punching process, the labor intensity is low, time and labor are saved, the working efficiency is improved, and meanwhile, waste materials are reduced according to the size of the plate materials.

Description

technical field [0001] The invention relates to an auxiliary device in the processing process of a punching machine, in particular to an automatic feeding and discharging structure of a punching machine for punching an iron wine box cover plate. Background technique [0002] A punching machine is a stamping press. Compared with traditional mechanical processing, the stamping process saves materials and energy, and has high efficiency; therefore, in the manufacturing process of the end cover of the iron wine box, most of the end covers are stamped once to form by the stamping process. Yes, in the stamping process, most of the sheets are constantly moved for stamping, and most of them are moved manually during the process, which is labor-intensive, time-consuming and labor-intensive, and has low work efficiency, and the position of the sheet is not easy to control reasonably , There is a lot of waste, which cannot achieve the rational utilization of resources; after stamping a...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a punch die structure for automatic discharge, which solves the problem of high labor intensity, time-consuming and labor-intensive work, low work efficiency, and the problem of sheet metal movement when manually moving the sheet material. The position is not easy to control reasonably, there are many waste materials, and the rational utilization of resources cannot be achieved. After stamping and forming, most of the formed end caps are removed manually, which is labor-intensive, time-consuming and labor-intensive, and has low work efficiency.
