Description

Technical Field

[0001] The invention relates to the field of plate processing and production, in particular to a production system for refrigerator side panels. Background Art

[0002] The existing refrigerator side panels need to go through multiple steps to produce the required shape. When producing the refrigerator side panels, generally, the processes of material selection, punching, bending, etc. are required.

[0003] The existing refrigerator side panel forming process has a low degree of automation and a large amount of labor for workers. It is difficult to coordinate the various production steps and equipment of the refrigerator side panels to achieve the needs of automated production processes to improve the forming quality and work efficiency of the refrigerator side panels.

[0004] In addition, the workstations of various processes of traditional refrigerator side panels are arranged rather messily in the factory area, and the transportation and transfer of materials between workstations wastes a lot of working hours, which is not conducive to improving the production efficiency of refrigerator side panels.

[0005] When the side panels of the refrigerator are punched and produced using a traditional punching machine, generally one punching machine can only perform one punching operation. When there are different types of plates on the production line, the simplest operation is to replace the punching head; therefore, it is impossible for a traditional production line to achieve mixed production of parts of different types, and it is even more impossible to achieve different punching operations on the same plate.

[0006] The traditional use of a single punching device to achieve a single punching effect also affects the overall processing and forming efficiency of the sheet metal to a certain extent.

[0007] When the side panels of the refrigerator are bent, especially the groove forming and end bending operations of the side panels of the refrigerator, a CNC (Computer Numeric Control) bending machine is generally used for the operation.

[0008] CNC (Computer Numeric Control) bending machine, also known as CNC bending machine, is an automated bending machine controlled by a program and used to bend thin plates.

[0009] However, the existing bending machines have a relatively complex overall structure and a relatively large overall weight, which is not conducive to improving the bending efficiency of the plates.

[0010] In addition, when the existing bending machine is bending, the plate lacks a positioning mechanism, and the plate to be bent is prone to warping or offset, affecting the bending accuracy.

[0011] At the same time, the existing upper die bar control method of the bending machine is relatively simple, and it is not possible to select whether the upper die bar is involved in the bending work according to needs; resulting in a reduction in the applicable scenarios of the bending machine.

[0012] After searching, the existing patents 201610712741.1-Fully automatic intelligent track plate punching production line and 201620148882.0-A CNC bending machine equipped with 90-degree turning have not clearly solved the technical problems mentioned above.

[0087] In addition, because the structure of the punching die frame belongs to the existing technology, the innovation here is not in the specific structure of the die frame, so the specific structure of the punching die frame will not be described in detail here.
