Processing method and device of metal shell brattice for cambered refrigerator

Abstract

The invention discloses a processing method and a device of a metal shell brattice for a cambered refrigerator. The device comprises a first station and a second station which are arranged front and back along the conveying direction, wherein two pressure punching machines which are arranged at intervals are arranged at the first station, and a linear plate shearing machine is installed at the second station. When a brattice workpiece is processed, firstly, the two pressure punching machines are used for punching the excess materials of the cambered parts at the two sides of the workpiece to form cambered line segments at the two sides of the workpiece; and then, the linear plate shearing machine is used for shearing off the excess materials of the linear part in the middle of the workpiece. The processing device is relatively portable and has small space occupation and low manufacturing cost. Moreover, the excess materials of the workpiece in the processing procedure are divided intothree parts, the excess materials can be discharged easily, the automated operation can be realized easily, and the production efficiency can be greatly improved. In addition, by adjusting the distance between the two pressure punching machines and controlling the shearing stroke of the linear plate shearing machine, the device can be used for processing brattice workpieces of various specifications and has strong universality.

Description

technical field [0001] The invention relates to a processing method and a processing device for an arc-shaped refrigerator metal shell enclosure, in particular to a processing method and a processing device for a metal sheet material combining arcs and straight lines. Background technique [0002] The refrigerators used in supermarkets and stores to hold ice cream, ice cream and other commodities are usually horizontal refrigerators. The outer shell of the horizontal refrigerator is composed of a flat back plate and a C-shaped hoard made of bent metal sheets, such as figure 1 , figure 2 . In order to facilitate customers to watch the goods in the cabinet, the top surface of the horizontal freezer is usually designed as an arc, the middle top surface of the C-shaped enclosure is a straight line, and the tops on both sides are arcs; it is used to bend the C-shaped enclosure The metal sheet must be a structure with arcs on the left and right sides and a straight line in the ...

AI Technical Summary

Problems solved by technology

Its molding precision is high, but the mold cannot be used universally, and one set of mold can only produce one type of refrigerator

Moreover, the size of the mold is huge, the press machine tool used for processing is also huge, and the processing machinery is heavy, takes up a large space, and is expensive

In addition, the leftover material after blanking is irregular and long, it is difficult to automatically blank the material in the mold, it is difficult to realize automatic operation, and it is difficult to improve production efficiency
