Problems solved by technology

[0004] There are some deficiencies in the existing positioning devices for steel strips. Most of the positioning devices rely on positioning rollers for positioning. However, the existing positioning rollers are cylindrical, and the contact surface with the steel strip is small. Misalignment and deviation will lead to work errors and affect welding accuracy

Abstract

The invention discloses a strip steel positioning device of a straight seam pipemill. The strip steel positioning device comprises a base, two lower box bodies are fixedly mounted at the top end of the base, when a steel strip moves and edges and corners are in contact with the steel strip, extrusion rubber blocks are arranged, so that the steel strip can be well clamped and driven to move, normal advancing of the steel strip is guaranteed, sliding of the steel strip is avoided, when the polygon rotates to the movement state that the extrusion rubber blocks interact with the edges, the side wall of an extrusion plate is in contact with the upper surface and the lower surface of the steel strip, the two sides of the extrusion plate are arranged to be arc-shaped, so that jamming is avoided, therefore, the extrusion plate and the steel strip can be smoothly alternated, the occurrence of dislocation is avoided, a cylinder cover is arranged on a spring cylinder, so that an internal second spring can be conveniently replaced, on one hand, the maintenance efficiency can be improved, and on the other hand, the second spring with different strengths can be replaced, so that the device is suitable for steel strips with different thicknesses and strengths.

Description

technical field [0001] The invention relates to the field of straight seam welded pipe machines, in particular to a strip steel positioning device for straight seam welded pipe machines. Background technique [0002] The pipe welding machine is used for continuous deformation welding of strip steel and online fixed-length industrial stainless steel pipe production. The technology of straight seam welded pipes at home and abroad is constantly improving, and industrial straight seam welded pipes in different fields have partially replaced seamless steel pipes. Because welded steel pipes are widely used, the production line process is simple, the equipment investment is small, the effect is quick, and the length standard is required, it is an investment manufacturer. Preferred industry equipment. [0003] The process flow is: uncoiling→automatic feeding→shear butt welding→feed-guiding leveling→rough and fine forming→welding→inner weld leveling→outer weld polishing→bright (blac...
