Welding head of stainless steel cold rolling production line welding machine

Abstract

The invention discloses a welding head of a stainless steel cold rolling production line welding machine. Comprising a first nut, a pressing plate, a welding wheel, a first gear, a first bolt, a main shaft, a first bearing, a main body frame, a second bearing, a concave copper ball, a second nut, a second bolt, a conductive copper plate, a disc spring, a third nut, a third bolt, a fourth bolt, a fixing ring, a cooling copper plate, a first sealing ring, a flange, a second sealing ring, a convex copper ball, a fourth nut, an upper base, a fifth bolt and a lower base. According to the stainless steel cold rolling welding head, the independently designed welding head can meet the production and use requirements of stainless steel cold rolling, use of an imported welding head is replaced, and the cost of spare parts is greatly reduced; by means of the independently-designed welding head structure, the welding efficiency and precision of the welding machine can be improved, and the welding stability and the welding quality are both improved; the contact stress is controlled through the disc spring, and the service life of the welding head is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of welder horns, in particular to a welder horn for a stainless steel cold rolling production line. Background technique [0002] The stainless steel cold rolling plant has many production processes and needs to go through harsh working conditions such as continuous annealing and pickling. The production line needs to operate continuously. If a shutdown occurs, it will seriously affect the production rhythm of the front and rear processes and cause an increase in production costs. Therefore, it is necessary to The strip steel is welded to meet the above working conditions. In order to improve the quality of the weld seam and prevent the strip from breaking and cutting the surface of the work roll on the production line, most of the welding machines in the stainless steel cold rolling plant use imported narrow lap resistance welding machines. The welding head of the welding machine is the core spare part that...

[0002] The stainless steel cold rolling plant has many production processes and needs to go through harsh working conditions such as continuous annealing and pickling. The production line needs to operate continuously. If a shutdown occurs, it will seriously affect the production rhythm of the front and rear processes and cause an increase in production costs. Therefore, it is necessary to The strip steel is welded to meet the above working conditions. In order to improve the quality of the weld seam and prevent the strip from breaking and cutting the surface of the work roll on the production line, most of the welding machines in the stainless steel cold rolling plant use imported narrow lap resistance welding machines. The welding head of the welding machine is the core spare part that directly determines the welding quality, so foreign manufacturers impose a strict technical blockade on it. If the welding head spare parts are needed, they can only be imported from abroad, resulting in high spare parts costs and long procurement cycles.
