Title:
ELECTRODE PRESSURE APPLICATION MECHANISM FOR RESISTANCE WELDING MACHINE, RESISTANCE WELDING MACHINE, WELDING METHOD, AND PRODUCTION METHOD FOR ELECTROMAGNETIC SWITCH
Document Type and Number:
WIPO Patent Application WO/2021/260985
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrode pressure application mechanism which is for a resistance welding machine, and with which it is possible to control pressure applied on a workpiece without depending on pressure applied by a resistance welding machine body. The electrode pressure application mechanism moves an upper electrode (2) up and down by means of a pressure application mechanism of the resistance welding machine body, and applies pressure and performs welding on a pair of workpieces (30, 31) placed between the upper electrode (2) and a lower electrode (5). The electrode pressure application mechanism is characterized by comprising: a load-receiving part (6) which is provided to the lower electrode (5) and which is in contact with the upper electrode (2) so as to receive the pressure applied by the resistance welding machine body; and a movable electrode (4) which is provided to the upper electrode (2) via an elastic member (3) and which comes into contact with the workpiece (30) when pressure is applied. The electrode pressure application mechanism is characterized in that the pressure applied on the workpieces (30, 31) is controlled by the pressure applied by the elastic member (3).
