Damping blanking device for stamping blank part

Abstract

The invention discloses a damping blanking device for a stamping blank part. The damping blanking device comprises an upper mould and a lower mould, wherein multiple sets of damping blanking assemblies are arranged on the periphery of a stamping position of the blank part on the lower mould; each damping blanking assembly comprises a damping blanking component and a fluid storage space; the damping blanking component comprises a blanking stopping nail; the blanking stopping nail is arranged in the lower mould; the fluid storage space is arranged in the lower mould; a fluid damping medium is filled in the fluid storage space; the blanking stopping nail passes through the fluid storage space and extends out of the upper surface of the lower mould. The damping blanking device for the stamping blank part has the beneficial effects that the springback of the blank part is reduced, the damage to the edge of the blank part caused by collision is reduced or avoided, and the abrasion caused by frictional damping is avoided.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a damping blanking device for stamping blanks. Background technique [0002] In the automatic feeding of single-piece sheet metal stamping production, the placement of the workpiece to be processed in the mold is very important, which is mainly reflected in the placement time and workpiece positioning. The placement time and workpiece positioning are the main factors affecting the stamping frequency. The space in the stamping die is narrow, and the placement deviation of the workpiece in the die is often small, and the allowable placement time for high-frequency stamping is extremely short. The existing patents 201020260990.x and 201220098915.7 have achieved good results in the realization of fast feeding, but there is a defect that the damping and feeding device wears out after long-term use and the damping effect is reduced, and the blank rebounds, causing the placement positi...

The existing patents 201020260990.x and 201220098915.7 have achieved good results in the realization of fast feeding, but there is a defect that the damping and feeding device wears out after long-term use and the damping effect is reduced, and the blank rebounds, causing the placement position to deviate beyond the limit, especially for larger When the blank is fed quickly, it is more likely to cause damage to the outer edge of the blank and the deficiencies of the offset of the placement position exceeding the limit
