Automatic punching mechanism for aluminum plate punching

Abstract

The invention discloses an automatic punching mechanism for aluminum plate punching. The mechanism comprises a punching machine bracket, a support plate and a movable punching rod; the upper end of the punching machine bracket is fixedly connected with the support plate; a first limiting groove and a first limiting column are arranged on the support plate; the side surface of the support plate ismovably connected with a fixed plate; through arrangement of a punching device, when aluminum plates are punched, surrounding annular blades firstly cut the aluminum plates, so that the cracking condition can be reduced during punching; an elastic circular plate is arranged in a template hole, and is compressed to a template groove during punching to eject onto a template; after punching, the elastic circular plate returns the punched aluminum plates; and through cooperative arrangement of a punching head and the template, and arrangement of a cutting device on the punching head, punched holescan be punched more smoothly, and the burr phenomenon of the aluminum plates is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an automatic punching mechanism for punching holes in aluminum plates. Background technique [0002] The stamping machine generally drives the flywheel through the motor, and through the clutch, the transmission gear drives the crank linkage mechanism to move the slider up and down, and drives the drawing die to punch, bend, cut, etc. the material; In the process of punching the material, in order to achieve the purpose of easy operation, but it still has the following disadvantages in actual use: [0003] 1. In the prior art, because the aluminum sheet is relatively soft and brittle, it is prone to cracking when the general stamping machine is stamping, which not only affects the product quality, but also causes waste of materials; [0004] 2. In the prior art, the aluminum sheet generates heat during the punching process, which makes the punched aluminum sheet so...

AI Technical Summary

Problems solved by technology

[0003] 1. In the prior art, because the aluminum sheet is relatively soft and brittle, it is prone to cracking when the general stamping machine is stamping, which not only affects the product quality, but also causes waste of materials;

[0004] 2. In the prior art, the aluminum sheet generates heat during the punching process, which makes the punched aluminum sheet soft and easy to stick to the template hole, and it is not easy to clean;

[0005] 3. Due to the brittle and soft nature of the general aluminum plate, the general stamping head is easy to cause burrs and unevenness in the aluminum hole when stamping and punching, which greatly affects the quality of the product
