Problems solved by technology

The disadvantages of the existing process are: 1. Since the coiling and welding need to be completed step by step on two machines, there are many processes and time-consuming workpiece transfer, resulting in low production efficiency; 2. Due to the flat surface of the overlapping plates at the intersection of the cylinders 3. Due to the overlapping size of the plates at the junction of the cylinders, the positioning accuracy is low

Abstract

The invention discloses a resistance welding machine capable of automatically rolling plates. The resistance welding machine comprises a rack, a rotating welding wheel is arranged in front of the rack, the welding wheel is connected with a front-back sliding device and a first lifting device, a cylindrical lower welding electrode extending in front of the rack is arranged below the welding wheel,and a left arc stamping die and a right arc stamping die are arranged on the left side and the right side of the lower welding electrode correspondingly. The left arc stamping die and the right arc stamping die are connected with a left sliding device and a right sliding device correspondingly, a lower arc stamping die is arranged below the lower welding electrode, a second lifting device is connected below the lower stamping die, and the left arc stamping die, the right arc stamping die and the lower arc stamping die can be spliced into a cylinder with a welding gap. The resistance welding machine capable of automatically rolling the plates has the advantages of simple process, accurate workpiece positioning, high production efficiency, good welding quality and the like.

Description

technical field [0001] The invention relates to a resistance welding machine, and in particular discloses a resistance welding machine for automatic plate rolling. Background technique [0002] refer to figure 1 . The welding process of the existing cylindrical straight seam workpiece includes two steps of coiling and welding. The plate rolling process curls the plate P into a cylinder, and a part of the plate is reserved at the intersection of the cylinder to overlap. The welding process adopts a resistance welding machine, and the resistance welding machine includes a flat upper welding electrode 01 and a cylindrical lower welding electrode 02. When welding, first put the cylinder P into the cylindrical lower welding electrode 02, and the operator fixes the cylinder P by hand, so that the overlapping size of the plates at the intersection of the cylinder P meets the requirements; then start the air pressure device, and put the upper electrode 01 is pressed at the inter...
