Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to an aluminum plate punching device with a material ejection mechanism. Background Technology

[0002] Aluminum sheet blanking is a stamping process that uses a die to separate part of the aluminum sheet material or workpiece from another part of the material, workpiece, or scrap. It usually uses the cutting edge of the die to shear and deform the sheet material along a certain contour line and separate it. The ejection mechanism in aluminum sheet blanking refers to the mechanism used to smoothly push the blanked workpiece or scrap out of the die during the aluminum sheet blanking process.

[0003] Existing ejection mechanisms mostly involve the use of a punch cutter and a punch die for ejection. The scrap material after punching is guided centrally through the ejection port and collected in a collection box below. This structure is relatively simple, and collisions between plates are prone to occur during the ejection process, leading to workpiece damage. Furthermore, manual removal and recycling of the collection box is still required afterward, and some of the scrap material after punching will also enter the box. The operation is cumbersome and the production efficiency is low. Therefore, there is an urgent need for an aluminum plate punching device with an ejection mechanism. Utility Model Content
