Automatic wire box punching machine

Abstract

An automatic wire box punching machine comprises a rack assembly, a die assembly arranged in the rack assembly and a punching assembly arranged in front of the die assembly. The punching assembly is connected with shaft sleeves in guide holes of the die assembly through guide columns on the punching assembly, and the punching assembly can slide forwards and backwards along the guide holes. The dieassembly comprises a fixing base and a female die arranged in front of the fixing base. The female die is internally provided with material pushing blocks and material pushing springs arranged in thefixing base. The material pushing springs outwards push the material pushing blocks all the time. The punching assembly comprises a discharging plate, a material pushing mechanism arranged behind thedischarging plate and a plunger chip arranged between the material pushing mechanism and the discharging plate, the plunger chip is located in a punch hole of the discharge plate, and the plunger chip moves forwards and backwards in the punch hole. The part between the material pushing mechanism and the discharging plate is provided with retreating springs. The retreating springs are arranged between the material pushing mechanism and the discharging plate. The automatic wire box punching machine has the beneficial effects that manual operation is replaced by mechanization, the labor intensity of workers is reduced, and the punching efficiency is improved.

Description

technical field [0001] The invention relates to a punching machine, in particular to an automatic punching machine for wire boxes. Background technique [0002] Junction box is one of the important auxiliary materials in electrical construction, and it is widely used in various decoration occasions. Generally, during production, the wire box is required to be provided with through holes on its four sides to facilitate the passage of wires. In the prior art, the device for punching the wire box is generally an ordinary punching machine tool. The wire box is manually put into the mold of the punching machine tool, and then the pedal switch is pressed with the foot, and the wire box is punched out through the punch. The hole on one side, and then manually turn the other side and then punch until the four sides are stamped. However, this method requires too much manual intervention, which consumes a lot of labor costs, and the production efficiency and finished product effect ...

AI Technical Summary

Problems solved by technology

However, this method requires too much manual intervention, which consumes a lot of labor costs, and the production efficiency and finished product effect are very unsatisfactory or even low. Improper operation, causing injury to workers

At present, some factories no longer use traditional stamping machine tools, and use punching machines to automatically punch holes for wire boxes, which can only replace manual operations. The punching dies are complex and cumbersome, with unstable structures, low service life, and fast replacement. The important thing is that the punching efficiency is still low, the operation is cumbersome, and the production cost is high
