AI Technical Summary

Technical Problem

During the stamping process of the existing stamping hole device of the car seat skeleton, the feed rod is not stable, resulting in elastic deformation and reduced service life. At the same time, the workpiece is difficult to remove in the positioning mold cavity groove.

Method used

A punching device including a hydraulic cylinder, a mounting plate, a punch, a pushing mechanism and a pushing mechanism are designed. The hydraulic cylinder drives the mounting plate downward, and the punch performs stamping operation; the pushing mechanism uses the coordination of the limiting plate and the spring to ensure the stability of the punch and the service life of the spring; the ejecting mechanism uses electric push rods and pushing plates to facilitate the removal of the workpiece from the positioning mold.

Benefits of technology

It improves stability during stamping, extends the service life of the spring, simplifies the workpiece removal process, and improves work efficiency.

Abstract

The utility model discloses a punching device of an automobile seat framework, which relates to the technical field of punching hole devices and comprises a punching table, a mounting frame is fixedly mounted at the upper end of the punching table, a hydraulic cylinder is fixedly mounted at the upper end of the mounting frame, a mounting plate is fixedly mounted at the output end of the hydraulic cylinder, a punch is fixedly mounted at the lower end of the mounting plate, and the punch is fixedly mounted at the lower end of the mounting plate. Pushing mechanisms are symmetrically arranged on the inner side of the punch, and a positioning die is fixedly installed at the upper end of the punching table. By adopting the structure, after a workpiece is punched in the cavity groove of the positioning die, the electric push rod on the fixed plate at the waste hole is started, so that the push plate connected with the output end of the electric push rod slides at the waste hole; and meanwhile, the two push columns connected to the upper end of the push plate can extend into the through holes of the positioning mold to push the workpiece out of the positioning mold, so that a worker can conveniently take out the workpiece.
