Welding forming method of wave plate type seat frame

Abstract

The invention relates to a welding forming method of a wave plate type seat frame. The welding forming method comprises the following processes: firstly, performing mold arrangement and installation and welding on two punched and cut support straight pipes, end part connection blocks and middle connection blocks to form a plane frame structure; secondly, performing mold arrangement and installation and welding on a wave plate and the plane frame structure to form a plane structure with the wave plate; and thirdly, performing integral bending and installation and welding on the plane structure with the wave plate to form the wave plate type seat frame. According to the welding forming method provided by the invention, the various composition parts are subjected to mold arrangement and installation and welding, compared with the special mold arrangement and installation and welding method in the prior art, a mold is simplified, the mold arrangement is convenient, the operation difficulty and the labor intensity are greatly reduced, the production cycle is shortened, the production efficiency is improved, the original amount of 50 pieces produced by every person every day is increased to the amount of 200 pieces by every person every day, in addition, the mode that the various composition parts are integrally bent and welded after being welded and fixed is adopted, so that the influences of welding deformation are reduced, and the welding forming precision and the production quality are improved.

Description

technical field [0001] The invention relates to a welding and forming method for an iron seat frame, in particular to a welding and forming method for a wave plate type seat frame. Background technique [0002] The wave plate seat frame is a recently popular structure on iron chairs. It is formed by bending and welding the upper and lower support tubes and the wave plate between the two support tubes, and welded at the ends of the two support tubes. There are end connection blocks, and a middle connection block is welded at the bending position. At present, the welding forming method of the corrugated plate seat frame is as follows: [0003] 1) Bending and welding the single supporting straight pipe after punching the incision along the incision to form a single-bend pipe structure; [0004] 2) Arranging molds and welding the two bent pipes, the end connecting block and the middle connecting block to form a seat-like frame structure; [0005] 3) Bending the corrugated boa...

AI Technical Summary

Problems solved by technology

[0007] 1. The corrugated board is used for spatial mold arrangement and welding, so the operation is difficult and laborious, which affects the production efficiency;

[0008] 2. The upper and lower support tubes are individually bent and welded, which on the one hand leads to a long production cycle and low production efficiency. On the other hand, due to the influence of welding deformation of the single support tube, the forming quality of the two support tubes after welding is reduced.

[0009] 3. Both the second process and the third process are arranged in space, so the mold used is more complicated and the operation is not convenient
