Box body welding production line and production method

Abstract

The invention discloses a box body welding production line and a production method. The production line comprises a plate discharge hole forming equipment line, a rolling forming line, a punching device, a bending device and a welding device; the plate discharge hole forming equipment line is used for leveling steel and punching the surface of the steel, and a material plate is manufactured; the rolling forming line is used for rolling a bending edge on the material plate; the punching device is used for cutting off the material plate into a plurality of groups, each group of material plates comprises four continuous sections, and the four sections are corresponding to four side wall plates of the box body; the bending device is used for bending the cut material plate into a side wall frame of the box body; and the welding device is used for welding the frame into a whole box body. The full-automatic production line and process of punching, rolling, cutting, bending and welding are adopted, so that full-automatic forming from the steel plate to the box body is realized, the processing of hole forming and three-dimensional features on the side wall of the box body is completed once,the production efficiency is high, the labor cost is low, and the processing quality is high.

Description

technical field

[0001] The invention relates to a box body welding production line, and also relates to a box body welding production method. Background technique

[0002] The processing of metal boxes (such as metal coffins) generally needs to go through processes such as blanking, opening, assembly and welding.

[0003] At present, the main processes in the processing of metal cabinets are all done manually. The operator needs to load and unload the material from the coil, then measure the size, cut it, and then put it on the hydraulic punching machine to complete the hole opening and other operations, and then assemble the surrounding side walls separately by welding, and then pass the surrounding side wall material plates through Assembled together by welding. The disadvantages of this method are: (1) heavy workload, high labor cost, and difficult to guarantee the processing quality; (2) the shape of the side wall plate is relatively complicated, with many hemming stru...
