Plate spring stamping and bending equipment for trailer

Abstract

The invention discloses plate spring stamping and bending equipment for a trailer, and belongs to the technical field of bending equipment, the plate spring stamping and bending equipment comprises an upper die mounted on a hydraulic machine and a lower die mounted on a base through a plurality of first elastic parts, the upper die is a driving movement device, the lower die is a driven movement device, a profiled groove with an upward opening is formed in the lower die, and the profiled groove is used for containing a workpiece. The bottom of the upper die is matched with the groove in shape, a punching head is arranged in the middle of the upper die, and the bottom face of the upper die is connected with an abutting block capable of sliding towards the interior of the upper die through a belleville spring. During stamping, rigid connection is achieved, the stamping effect is good, elastic connection is achieved after stamping is completed, the damping effect is good, damage to a machine is reduced, and the service life of the machine is prolonged. Three procedures can be completed at the same time, working time is saved, products are not prone to dislocation in the machining process, and machining and positioning of all positions are more accurate.

Description

technical field [0001] The invention belongs to the technical field of trailers, and in particular relates to stamping and bending equipment for leaf springs used in trailers. Background technique [0002] Trailer damping is generally achieved by connecting a leaf spring between the axle and the car body. The leaf spring is a plate spring composed of no less than one piece of spring steel superimposed and combined. During the processing of the leaf spring steel, the straight plate is heated The final stamping and bending of the product, the processing procedure needs to be divided into three steps, namely, bending the leaf spring steel as a whole, punching the mounting hole in the middle of the leaf spring and bending both ends of the leaf spring steel. Many, and in the process of switching between multiple processes, repositioning is required, and the production efficiency is low; in the stamping process, due to the high impact force of the upper die, the normal lower die i...

[0002] Trailer damping is generally achieved by connecting a leaf spring between the axle and the car body. The leaf spring is a plate spring composed of no less than one piece of spring steel superimposed and combined. During the processing of the leaf spring steel, the straight plate is heated The final stamping and bending of the product, the processing procedure needs to be divided into three steps, namely, bending the leaf spring steel as a whole, punching the mounting hole in the middle of the leaf spring and bending both ends of the leaf spring steel. Many, and in the process of switching between multiple processes, repositioning is required, and the production efficiency is low; in the stamping process, due to the high impact force of the upper die, the normal lower die is not equipped with an anti-seismic device, and the upper die, workpiece and lower die When the mold contacts, it will cause great damage to the lower mold and has the disadvantage of low service life
