Automatic blanking device of hardware stamping die

Abstract

The invention discloses an automatic blanking device of a hardware stamping die, and relates to the technical field of hardware manufacturing. The automatic blanking device of the hardware stamping die comprises an automatic feeding and discharging mechanism, a stamping head and a stamping table, wherein the bottom of the stamping head is provided with the upper surface of the stamping table; thefront end of the upper surface of the stamping table is provided with the rear end of the automatic feeding and discharging mechanism; and the lower surface of the stamping head is provided with a rear end for automatic feeding and discharging. According to the automatic blanking device of the hardware stamping die provided by the invention, by combining a silicone rubber suction bottom, a sand storage part and an air pump, fine sand in the sand storage part is sucked into a pneumatic cavity of the silicone rubber suction bottom through suction force, the fine sand is tightly stacked on the surface of a stamping part through downward pressure and air pressure extrusion, and a gap between the silicone rubber suction bottom and the surface of the stamping part is blocked; and negative pressure is generated in a sealed adsorption cavity after air is pumped out, and the silicone rubber suction bottom and the surface of the stamping part are tightly adsorbed due to the air pressure effect,so that the problem that the stamping part with the frosted surface or the uneven stamping part falls off and is damaged in the sucker transportation process is solved.

Description

technical field [0001] The invention relates to an automatic blanking device, relates to the technical field of hardware manufacturing, in particular to an automatic blanking device for a metal stamping die. Background technique [0002] Stamping is to rely on presses and molds to apply external force to plates, strips, pipes and profiles, etc., to cause plastic deformation or separation, so as to obtain stamping parts of the required shape and size. In order to speed up the stamping processing efficiency, stamping Most of the time, the automatic loading and unloading method is adopted, and the auxiliary mechanical equipment or mechanism is used to complete the automatic loading of the original sheet and removal of the stamping parts. The following problems exist in the prior art: [0003] 1. In the prior art, when automatically loading and unloading plates with frosted or uneven surfaces, because the surrounding of the suction cup cannot be close to the surface of the plate...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to provide an automatic blanking device for metal stamping dies, one of the purposes of which is to have the function of picking up matte or uneven flat plates, and to solve the problem that the surrounding of the suction cup cannot be close to the surface of the plate to form a sealed cavity. There is a problem that the suction cup and the surface of the stamping part are not firmly adsorbed, and the stamping part is damaged by falling; another purpose is to solve the problem that some automatic loading and unloading devices will choose to use the manipulator to clamp and grab the stamping part, but there is a problem of grasping When the stamping parts are clamped, the surface is easily scratched by the manipulator, which leads to the problem that the quality of the stamping parts is reduced, so as to achieve the effect that the surface of the stamping parts will not be damaged when grabbing
