Inserted copper-aluminum pipe resistance welder

Abstract

The invention discloses a welding machine, in particular to a plug-in copper-aluminum tube resistance welding machine. It includes the main body of the machine head, clamping cylinder, electrodes, output cable connectors, and clamping cylinder shaft, wherein an adjustable fixing member for the upper electrode is provided between the lower end of the clamping cylinder shaft and the upper electrode, and the lower electrode and the upper electrode are connected together. A lower electrode adjustable fixing piece is arranged between the lower fixing blocks of the main body of the machine head. The debugging of the welding machine of the invention is more convenient and accurate, and the debugging cost is low.

Description

technical field [0001] The invention relates to a welding machine, in particular to an insertion-type copper-aluminum pipe resistance welding machine. Background technique [0002] The current general-purpose plug-in copper-aluminum tube resistance welding machine has problems that are difficult to master and debug. The main defects lie in the following points: [0003] 1. The welding fixture of the original welding machine has no feasible concentricity adjustment structure, which cannot guarantee the concentricity of the workpieces at both ends and the balance of the clamping force on the front, rear and four sides. [0004] 2. After the adjustment, the concentricity accuracy is not enough, and the product quality is unstable, the reason is that the workpieces at both ends are adjusted [0005] When the concentricity is correct, it is proofread with copper platinum pads. [0006] 3. It takes 1 to 48 hours or even a few days to adjust the working hours of the unimproved we...

Problems solved by technology

[0002] The current general-purpose plug-in copper-aluminum tube resistance welding machine has problems that are difficult to master and debug. The main defects lie in the following points:

[0003] 1. The weldment fixture of the original welding machine has no feasible concentricity adjustment structure, and cannot guarantee the concentricity of the workpieces at both ends and the balance of the clamping force on the front, rear and four sides

[0004] 2. After the adjustment, the concentricity accuracy is not enough, and the product quality is unstable, the reason is that the workpieces at both ends are adjusted

[0006] 3. It takes 1 to 48 hours or even a few days to adjust the working hours of the unimproved welding machine, which leads to misproduction and difficult control of production management

[0007] 4. The waste of raw materials (copper and aluminum tubes) is serious during adjustment. Every time the electrode is changed or the welding machine cannot operate normally due to reasons that are difficult to judge, several kilograms of raw materials will be wasted every time it is debugged.

[0008] 5. It is difficult for ordinary technicians to master and debug the welding machine normally. Only professional technicians with at least half a year of practical experience can take up the post, which seriously hinders the development of enterprises engaged in copper-aluminum connecting pipe products.
