Automatic material remover for punch

Abstract

The invention relates to an automatic material remover for a punch. The automatic material remover comprises a blower for blowing a falling material under a material falling outlet of a punch die outof the punch die from one side of the punch die, wherein the blower is connected to an electromagnetic valve, the electromagnetic valve is connected to a proximity sensor, the proximity sensor is fixed on one side of an upper die of the punch die, a sensing insert which is used for being in sensing connection with the proximity sensor during die closing is arranged at one side of the proximity sensor, and the sensing insert is fixed with one side of a lower die of the punch die. The blower can blow a material falling from the material falling outlet of the punch die out of the punch die at themoment when the punch die is closed, the proximity sensor can cooperate with the sensing insert to control the blower to open at the moment when the punch die is closed, so that the blower can be prevented from being in a normally opened state, consequently, the energy consumption of the blower can be reduced, and the service life of the blower can be prolonged; the falling material can be more easily blown away by the blower in the process of falling, so that the material removal effect can be improved, consequently, manual material removal can be thoroughly replaced, the efficiency can be conveniently increased, the cost is reduced, and safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of punching equipment, and in particular relates to an automatic material return device for a punching machine. Background technique [0002] Many stamping parts will produce blanking during the stamping and forming process. The blanking can be the waste that is punched and dropped from the product, or it can be the product that is punched and formed directly from the stamping belt. The blanking is generally It will fall directly from the blanking port of the stamping die to the bottom of the stamping die. When the blanking material under the stamping die accumulates a lot, it generally needs to be cleaned or collected manually. Otherwise, the blanking material will accumulate at the blanking port, making subsequent The blanking during the stamping process cannot be discharged normally, which affects the continuation of production; due to the high speed of the punching machine, in order to ensure safety, the...

[0002] Many stamping parts will produce blanking during the stamping and forming process. The blanking can be the waste that is punched and dropped from the product, or it can be the product that is punched and formed directly from the stamping belt. The blanking is generally It will fall directly from the blanking port of the stamping die to the bottom of the stamping die. When the blanking material under the stamping die accumulates a lot, it generally needs to be cleaned or collected manually. Otherwise, the blanking material will accumulate at the blanking port, making subsequent The blanking during the stamping process cannot be discharged normally, which affects the continuation of production; due to the high speed of the punching machine, in order to ensure safety, the blanking under the blanking port must be cleaned or collected after the punching machine is stopped, which will Affects efficiency, and it will take up more human resources, which is not conducive to reducing production costs; and when the blanking is a product, it is collected by manual use of fixtures in many cases, which is more dangerous and easy to cause industrial accidents
