Pneumatic shearing butt-welding machine

Abstract

The invention discloses a pneumatic shearing butt-welding machine, and belongs to the technical field of steel producing processing equipment. The pneumatic shearing butt-welding machine comprises a shearing welding machine body, wherein a shearing mechanism and a welding pressing mechanism are mounted on the shearing welding machine body; the shearing mechanism comprises a shearing air cylinder, an upper blade and a lower blade; one end of the upper blade is hinged with a cylinder rod of the shearing air cylinder through a linkage mechanism; the lower blade is oppositely tangential to the upper blade; the other end of the upper blade is hinged with a shearing bracket mounted on the shearing welding machine body; the shearing air cylinder controls the cylinder rod to extend out or retract through a rotary valve mounted on the shearing welding machine body, so that the upper blade is oppositely tangential to or far away from the lower blade; and a shearing pressing mechanism used for pressing the head and the tail of a to-be-sheared steel belt is supported through the shearing bracket. The pneumatic shearing butt-welding machine can complete shearing and welding of the steel belt, ensures shearing and welding quality of strip steel, remarkably improves production efficiency, has a feeding function among processes, can intensively recycle shearing waste heads, is small in space usage, is low in labor intensity, is low in cost, is safe to operate, and is very convenient to use.

Description

technical field [0001] The invention belongs to the technical field of steel production and processing equipment, and in particular relates to a pneumatic shear butt welding machine for butt welding wire and plate. Background technique [0002] The high-frequency straight seam welded pipe unit feeds metal strips such as steel strips, aluminum strips, and copper strips of a certain specification into the equipment, and curls the metal strips into tube blanks through forming rollers, and then uses the high-frequency proximity effect and skin effect to make the tubes The edge is quickly heated to the welding temperature, and the welding is completed under the extrusion force of the extrusion roller, and finally the welded pipe shape of the required specification is formed through cooling, sizing and straightening steps. [0003] At present, the straight seam welded pipe production equipment used to roll medium and wide steel strips for straight seam welded steel pipes, the head...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a pneumatic shearing butt welding machine, which can complete the shearing and welding of the steel strip, can not only ensure the shearing and welding quality of the strip steel, but also significantly improve the production efficiency. It has excellent feeding function and can recycle the shearing waste head in a centralized manner, and it takes up less space, has low labor intensity, low cost, safe operation, and is very convenient to use, which can avoid the shortcomings and deficiencies existing in the prior art.
