Chair plate punching die replacing system

Abstract

The invention discloses a chair plate punching die replacing system which comprises an electric permanent magnetic chuck I, an electric permanent magnetic chuck II and an electric permanent magnetic chuck controller. The electric permanent magnetic chuck I is fixed to a sliding block of a punching machine. The electric permanent magnetic chuck II is fixed to a working table of the punching machine. The electric permanent magnetic chuck controller is arranged on one side of the punching machine. A punching die is arranged between the electric permanent magnetic chuck I and the electric permanent magnetic chuck II. The electric permanent magnetic chuck controller is in line connection with the electric permanent magnetic chuck I, the electric permanent magnetic chuck II and a control cabinetof the punching machine. The control cabinet of the punching machine is connected with a pedal line switch. According to the system, magnetizing of the electric permanent magnetic chucks is utilizedfor attracting an upper die plate and a lower die plate of a die to lock the die, locking is fast, fastening is firm, the machining process is safe, damage to the die is avoided, and the quality of achair plate hole position machined through punching is ensured. While time for adjusting is shortened, the punching quality of the chair plate and the service life of the die are guaranteed, and it isensured that safety accidents like crushing injuries are avoided when the punching machine carries out punching on the chair plate.

Description

technical field [0001] The invention relates to the field of furniture production, in particular to a mold changing system for a seat seat plate punching mold. Background technique [0002] At present, the hole position of the seat plate is processed by punching the mold on the punching machine with a punching needle. The original mold changing method uses manual mold changing, and the mold locking is fixed by screws, that is, several people hold the mold to the punching machine together. On the workbench, after adjusting the position correctly, use screws to fix the upper and lower templates of the mold on the workbench respectively, raise the upper template, insert the seat plate on the seat plate of the mold, and step on the foot switch after the clamping is not loose. , the punching of the upper template can be used to process the hole position of the seat plate. Due to the wide variety of seat boards, frequent mold changes are required, and the weight of the mold is he...

AI Technical Summary

Problems solved by technology

Due to the wide variety of seat boards, frequent mold changes are required, and the weight of the mold is heavy. Manual mold change is time-consuming and labor-intensive, and there are hidden dangers of crushing and top damage; the screw-fixed clamping method requires a few points of the mold to be stressed, and punching The impact force during the hole process is large, the mold is easily damaged by extrusion deformation, and the punching quality cannot be effectively guaranteed; frequent mold changes, large loss of screws and screw ports, and reduced service life
