Abstract

The invention provides a four-roller connection-rod vacuum electron beam wire feeder, relates to a vacuum electron beam wire feeder, and belongs to the field of the welding machinery. The invention aims to solve the problems of the existing vacuum electron beam wire feeder that wire feeding rollers and wire pressing rollers are easily worn, the distance between the wire feeding rollers and the wire pressing rollers can not be automatically adjusted according to the diameter of welding wires, etc. The main structure of the four-roller connection-rod vacuum electron beam wire feeder comprises a servo motor, two wire feeding rollers, two wire pressing rollers, a connection rod, a U-shaped groove and spring limit mechanisms, wherein, one wire feeding roller is fixed on the rotating shaft of the servo motor, the wire feeding roller rotates as the motor rotates, power is supplied for the other wire feeding roller through the connection rod; the two wire pressing rollers are fixed on a support through studs and nuts; the four rollers are coplanar; the two wire pressing rollers supply pressing forces for the wire feeding operation; and the four rollers and the connection rod jointly form the four-roller connection-rod vacuum electron beam wire feeder. The four-roller connection-rod vacuum electron beam wire feeder provided by the invention is mainly applied in the fields such as dissimilar material vacuum electron beam welding, self-forming technology, material surface cladding, efficient optimization of the performances of welding seams, defect control and the like.

Description

technical field [0001] The invention relates to a vacuum electron beam wire feeder, which belongs to the field of welding machinery. Background technique [0002] At present, the existing technology is mainly gas-shielded welding wire feeder, which mainly includes hyperbolic planetary roller wire feeder, double-roller planetary wire feeder and triple-roller planetary wire feeder according to the wire feeding principle. Each wire feeder has its own advantages and disadvantages. For example, the hyperbolic planetary roller wire feeder has a large wire feeding force, a small wire feeding resistance, and a stable wire feeding speed. However, during the wire feeding process, the wire and the wheel are in line contact, resulting in The welding wire is deformed greatly. The double-roller planetary wire feeder and the three-roller planetary wire feeder do not need deceleration and straightening systems, so the structure is simple, but they have the disadvantages of long contact tim...
