Large-section longitudinal and transverse bidirectional force closure friction welding machine and working method thereof

Abstract

The invention relates to a large-section longitudinal and transverse bidirectional force closure friction welding machine and a working method thereof. The large-section longitudinal and transverse bidirectional force closure friction welding machine is reasonable in structure, can effectively solve the problem of friction welding of large-section materials with the same size, and improves the welding quality, shortens the welding time, reduces the energy consumption and improves the economic benefits of enterprises for the electrolytic aluminum industry. The welding machine is of a horizontal structure as a whole and comprises a variable-frequency main motor (1), a main shaft box (4), a hydraulic clamp (5), a guide rod linkage clamp (6), a workbench (7), an upsetting device (9), a machine base (10) and an electric control signaling device (11). The upsetting device pushes the workbench to move longitudinally, after a steel claw makes contact with a steel beam residual steel claw, the variable-frequency main motor is started, the steel claw in the hydraulic clamp is driven by a main shaft to rotate at a high speed, a large amount of friction heat is generated between the steel claw and the steel beam residual steel claw, after the welding temperature is reached, the steel claw stops rotating, upsetting force is applied to a steel claw steel beam, after a period of time, a guide rod steel beam moves in the opposite direction in the longitudinal direction, and a welded new steel claw is taken out of the hydraulic clamp.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a large cross-section vertical and horizontal two-way force-closed friction welding machine and a working method of the large-section vertical and horizontal two-way force-closed friction welder, which is mainly used to solve the problem of large cross-section size and the same material friction welding. Background technique [0002] The electrolytic anode in electrolytic aluminum equipment is composed of carbon block, steel claw and aluminum guide rod. The steel claw will be ablated or deformed in the process of electrolytic aluminum liquid. After cutting off the steel claw, re-weld the new steel claw to the steel Claws on steel beams. At present, welding methods such as manual arc welding or explosive welding are mostly used. The existing problems are long welding time, unstable welding quality, high labor intensity, high energy consumption, and high cost, which have...

Problems solved by technology

At present, welding methods such as manual arc welding or explosive welding are mostly used. The existing problems are long welding time, unstable welding quality, high labor intensity, high energy consumption, and high cost, which have become restrictions on energy saving, consumption reduction, emission reduction, and increase in aluminum industry. efficiency bottleneck

[0003] In order to solve the above problems, a friction welding machine with a large cross-sectional size can be used, but the welding area is large, the friction torque between steel and steel materials is large, and the upsetting force is large.

Therefore, there are technical difficulties such as large force, large volume, large inertia, and high dynamic performance requirements of the whole machine when the whole machine is working.
