Large-upsetting-force large-inertia force closure steel aluminum friction welding machine overall structure

Abstract

Provided is a large-upsetting-force large-inertia force closure steel aluminum friction welding machine overall structure. A machine tool base (26) and a machine tool base (20) are connected together, a variable frequency motor (1) is fixed to the machine tool base (26), an input shaft on a spindle box (4) is connected with a motor shaft through an electromagnetic clutch (3), an input shaft of the spindle box is connected with a steel claw hydraulic fixture (7), and the steel claw hydraulic fixture (7) can complete clamping of a steel claw; aluminum guide rod displacement fixtures (9, 11 and 12) of the same structure are in bearing connection through prestretching guide posts (15), auxiliary bearings (23) are connected with the lower portions of the three aluminum guide rod displacement fixtures (9, 11 and 12) and supported on a bearing guide rail (21) fixed to the machine tool base (20), fixture oil pipes (22) are inserted into the three aluminum guide rod displacement fixtures (9, 11 and 12), one end of an upsetting connector (13) is connected with the aluminum guide rod displacement fixture (12), the other end of the upsetting connector (13) is connected with an oil cylinder piston rod (14), and an oil cylinder (17) is fixedly supported by a bracket (16).

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a friction welding machine, in particular to an overall structure of a closed steel-aluminum friction welding machine with large upsetting force and large inertia force. Background technique [0002] Electrolytic anodes in electrolytic aluminum equipment are welded by steel claws and aluminum guide rods. At present, manual arc welding or explosive welding is mostly used for welding. The existing problems are long welding time, unstable welding quality, high labor intensity, and energy consumption. Large and high cost, it has become a bottleneck problem restricting energy saving, consumption reduction, emission reduction and efficiency increase in the aluminum industry. [0003] In order to solve the above technical problems, the large upsetting force and large inertia steel-aluminum friction welding machine can effectively solve the problem of friction welding of dissimil...

Problems solved by technology

[0002] Electrolytic anodes in electrolytic aluminum equipment are welded by steel claws and aluminum guide rods. At present, manual arc welding or explosive welding is mostly used for welding. The existing problems are long welding time, unstable welding quality, high labor intensity, and energy consumption. Large and costly, it has become a bottleneck problem restricting energy saving, consumption reduction, emission reduction and efficiency increase in the aluminum industry

The aluminum guide rod weighs about 280Kg and is about 3000mm long. If a vertical structure is adopted, the height of the machine tool will be high, inconvenient loading and unloading, difficult clamping, difficult to meet rigid requirements, low vibration resistance, difficult to control welding accuracy, and difficult operation , low safety factor and other issues
