High-strength chain welding machine

Abstract

The invention discloses a high-strength chain welding machine, and relates to the technical field of chain making devices. The high-strength chain welding machine comprises a welding machine main body, a chain conveying straightening guide rail used for guiding a chain is connected to the welding machine main body, a chain pulling piece used for intermittently pulling the chain on the chain conveying straightening guide rail backwards is arranged on a chain straightening guide rail, an anvil base abutting against the lower side of a chain ring to be welded and ejector rods abutting against thetwo ends of the chain ring to be welded are connected to the welding machine main body, and the ejector rods are slidably connected to the welding machine main body in the length direction of the ejector rods; and the welding machine main body is provided with a headstock and a lifting driving part which drives the headstock to move to the upper part of the chain ring to be welded; and the headstock comprises an electrode rotating shaft, two electrode conductors are connected to the headstock in a mode of rotating around the electrode rotating shaft, electrodes used for welding are arranged on the inner sides of the electrode conductors, and an electrode clamping oil cylinder used for driving the two electrode conductors to rotate is further hinged between the two electrode conductors. The high-strength chain welding machine has the beneficial effects of being stable in welding quality, high in efficiency, low in maintenance cost and simple in structure.

Description

technical field [0001] The invention relates to the technical field of chain making devices, in particular to a high-strength chain welding machine. Background technique [0002] In the production process of metal round link chains, controlling the flash butt welding process is the key factor to ensure the quality of the round link chains, so they are all produced and manufactured by special equipment. In the manufacture of high-strength round link chains, welding is indispensable. [0003] In the domestic market, resistance welding is used for the welding of high-strength circular link chains with wire diameters above 13mm-18mm, and German wafios equipment is basically used for wire diameters above 18mm; the international market is currently basically monopolized by German wafios. [0004] Domestic hand-welded round link chains will have electrode marks, and cannot be automatically deburred, which seriously affects the appearance of the product. [0005] The resistance we...

Problems solved by technology

[0004] Domestic hand-welded round link chains will have electrode marks, and cannot be deburred automatically, which seriously affects the appearance of the product

[0005] High-strength round link chains with a resistance welding wire diameter of 13mm-18mm or more have high requirements for wire materials, and because of the problem of large instantaneous current, the welding quality is unstable
