Refrigerator end folding door shell punch forming assembling die and production line with assembling die

Abstract

The invention relates to a refrigerator end folding door shell punch forming assembling die and a refrigerator end folding door shell automatic punch forming production line with the assembling die. The refrigerator end folding door shell punch forming assembling die comprises a punching bending die and a folding U end folding die, and the punching bending die and the folding U end folding die are installed on a punch machine. According to the refrigerator end folding door shell punch forming assembling die and the production line with the assembling die, since the working procedure of punching-edge folding and the working procedure of U-bending folding-end folding are integrated into two sets of dies, the dies are installed on the punching machine, the two sets of dies can both achieve the two working procedures quickly and separately, in addition, the dies produced by the two working procedures can be placed on one punching machine for production, so that the production time is greatly improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a combination die for stamping and forming of a refrigerator end folding door shell and a production line with the die, belonging to the field of refrigerator door shell production equipment. Background technique [0002] Existing high-end refrigerator doors all use borderless end-folding door shells, such as figure 1 The structure of this type of door shell shown is complex, and in addition to double-folding forming on both sides, both ends of the door shell also need to be bent and formed. [0003] In the current technology, in order to ensure the quality and grade of the door shell, especially the forming quality of the corners at both ends, the industry adopts single-process multi-step stamping to complete, such as figure 2 The process flow shown is: punching-edge folding-U-bending-end folding. There are four processes in total. The refrigerator sheet metal end folding door shell 10 is completed by multiple people on 4 pu...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an automatic stamping mold and production line for refrigerator end-folding door shells, which overcomes the need for punching-folding-folding U-bending-end-folding in the prior art to produce borderless end-folding door shells. The four processes are sequentially completed by multiple people on the punching machine, resulting in low production efficiency and increased manpower and financial resources.
