Description

Technical Field

[0001] This utility model relates to the field of blade welding technology, specifically a multi-point welding machine for producing hard alloy blades. Background Technology

[0002] Multi-point spot welding of carbide inserts plays a crucial role in the field of tool manufacturing and machining. During operation, two electrodes press the workpiece, causing the two layers of metal to form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous thermal fusion is formed at the two contact resistance points.

[0003] Chinese patent disclosure for a multi-point welding machine for blade production, publication number CN206263425U, includes a main control box and a welding box, as well as an auxiliary box and multi-point welding pads. The main control box houses a transformer with a voltage monitor electrically connected to it. An operation display screen is located at the front of the main control box. The auxiliary box is vertically connected to the lower right side of the main control box and contains a lifting device. Two lower electrodes are mounted on the upper part of the auxiliary box and connected to the lifting device. A column is fixed to the right side of the auxiliary box, with its top connected to the top of the main control box via a fixed frame. The welding box is mounted on the lower end of the fixed frame and contains a current booster and a telescopic spring. A pressing block and two upper electrodes are fixed to the lower end of the welding box. The pressing block and telescopic spring work together to enable rapid multi-point welding, improving work efficiency and ensuring safety during operation.

[0004] However, the device still has the following drawbacks: it places the blade at the welding point and welds directly, but during welding, the welded blade is removed and then the blade to be processed is installed, resulting in low welding efficiency. To address this issue, we propose a multi-point spot welding machine for producing carbide blades. Utility Model Content
