Cable-type welding wire double-twisting stranding machine

Abstract

The invention relates to a welding wire processing device, particularly to a cable-type welding wire double-twisting stranding machine. The cable-type welding wire double-twisting stranding machine comprises a stranding unit, an unwinding unit, a sizing and stress relieving unit, a traction unit and a winding unit, wherein two main shafts with center holes and side holes of the stranding unit are fixedly provided with two arched rocker arms which are arranged oppositely, the arm ends of the two arched rocker arms which are arranged oppositely are provided with arched belts which are connected with the two arched rocker arms in which threading inclined holes are formed, the inner sides of the arched belts are provided with a plurality of wire through holes, and the stranding unit, the traction unit and the winding unit are respectively driven by a standing motor, a traction motor and a winding motor. The cable-type welding wire double-twisting stranding machine has the advantages of being high in production efficiency and small in vibration noise.

Description

technical field [0001] The invention relates to a welding wire processing equipment, in particular to a cable-type welding wire double-twist stranding machine. Background technique [0002] The cable-type welding wire of the present invention is composed of a central welding wire and a coiled welding wire that revolves around the central welding wire. Usually, one central welding wire and six coiled welding wires with a diameter equal to the central welding wire are stranded. Since the cable welding wire can greatly improve the welding productivity of automatic welding and semi-automatic welding, it has attracted more and more attention from the welding industry. [0003] And the stranding equipment of this kind of welding wire mostly adopts tubular stranding machine. The maximum speed of the tubular stranding machine can only reach 1000 rpm at present, and the power of the motor is required to be very large. [0004] The double-twisting stranding machine used for steel co...

Problems solved by technology

In addition, use a motor connected to the main shaft to rotate the flywheel disc and drive the traction device to work at the same time, the transmission mechanism is complicated, and the stepless adjustment of the twist length cannot be realized

[0006] In view of the low production efficiency and high energy consumption of the existing cable-type welding wire tubular stranding machine mentioned above, a new cable-type welding wire double-twisting stranding machine is proposed, and the moment of inertia of the flywheel disk is minimized , the welding wire will not be stretched under high-speed rotation, and the twist length can be adjusted arbitrarily
