Dual-power-supply contact bridge full-automatic welding system

Abstract

The invention discloses a dual-power-supply contact bridge full-automatic welding system. The dual-power-supply contact bridge full-automatic welding system comprises a rotary disc arranged on a table; the upper surface of the rotary disc is uniformly and fixedly provided with eight locking fixtures which are identical in structure in the circumferential direction, and each locking fixture corresponds to one station; the table is provided with a plurality of mechanisms around the rotary disc; and the outer side of the first station is provided with a contact bridge feeding mechanism, the outerside of the second station is provided with a first feeding mechanism, the outer side of the third station is provided with a first welding mechanism, the outer side of the fourth station is providedwith a detection mechanism, the fifth station serves as a transposition station, the outer side of the six station is provided with a second feeding mechanism, the outer side of the seventh station is provided with a second welding mechanism, and the outer side of the eighth station is provided with a discharging mechanical hand. According to the dual-power-supply contact bridge full-automatic welding system, four-stage buffer pressurization and four-stage flexible heat generation are adopted, the system is suitable for multiple types of contacts and contact bridges, the production efficiencyis obviously improved, electric current consumption and pressure consumption are remarkably reduced, the electrode service life is prolonged, the percent of pass reaches 100%, and the equipment costis low.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to a full-automatic welding system with double power supply contact bridges. Background technique [0002] The combination of circular arc contacts and arc contact bridges has good current breaking ability, and has been widely used in dual power contact bridge systems. When welding existing dual power contact bridge products, the upper electrode and the lower electrode are basically installed correspondingly. , and the upper and lower electrodes of the straight plate contact bridge and the contact are aligned, and the vertical pressure is energized and heated to realize resistance brazing; but for the contact bridge with a thinner surrounding thickness, a thick middle thickness, and a large thickness ratio, the contact bridge is directly opposite to the contact Heating and pressing, this welding method has the following problems: [0003] 1) Because the middle of the contact is thic...
