Resistance welding of aluminum based on sociological principles and usage method thereof

Abstract

The invention discloses resistance welding of aluminum based on sociological principles and a using method of resistance welding. The resistance welding relates to a working box. A working space is arranged in the working box, wherein the front end wall of the working space communicates with the external space. A positioning mechanism is arranged in the working space. A force bearing block is fixedly connected to the lower end wall of the working space. The upper end surface of the force bearing block is internally provided with a force bearing groove, wherein the upper end wall of the force bearing groove communicates with the working space. A pressure spring is fixedly connected to the lower end wall of the force bearing groove. A force bearing block is fixedly connected to the upper endof the pressure spring, wherein the upper end of the force bearing block penetrates through the upper end wall of the force bearing groove, and the force bearing block is positioned in the working space. A grinding block is fixedly connected to the upper end of the force bearing block. A device is simple in structure and convenient to operate, and can perform oxide removal operation on the welding surface of aluminum or aluminum products to be subject to resistance welding, so that the quality of resistance welding, to be carried out next, of the aluminum and the aluminum products can be ensured, and the welding quality of resistance welding positions is not influenced due to interference of aluminum oxide.

Description

technical field [0001] The invention relates to the field of resistance welding, in particular to resistance welding of aluminum based on sociological principles and its application method. Background technique [0002] When aluminum and aluminum alloys are placed in the air for a period of time, they will be oxidized by oxygen in the air to form a layer of aluminum oxide protective film. This protective film has good heat resistance and insulation, and has a certain impact on the performance of the internal aluminum and aluminum alloys. It has a certain guarantee effect, but in the resistance welding of aluminum or aluminum alloy, this layer of aluminum oxide protective film will have a bad influence on the quality of resistance welding due to its heat resistance, so this layer of aluminum oxide film needs to be removed before resistance welding The protective film is removed, and resistance welding is performed in time before the aluminum oxide protective film is regenerat...

[0002] When aluminum and aluminum alloys are placed in the air for a period of time, they will be oxidized by oxygen in the air to form a layer of aluminum oxide protective film. This protective film has good heat resistance and insulation, and has a certain impact on the performance of the internal aluminum and aluminum alloys. It has a certain guarantee effect, but in the resistance welding of aluminum or aluminum alloy, this layer of aluminum oxide protective film will have a bad influence on the quality of resistance welding due to its heat resistance, so this layer of aluminum oxide film needs to be removed before resistance welding The protective film is removed, and resistance welding is performed in time before the aluminum oxide protective film is regenerated to ensure the quality of resistance welding

However, in the existing aluminum or aluminum alloy resistance welding pretreatment equipment, the processing of the welding surface of the aluminum or aluminum alloy block with a slope is more cumbersome.
