Four-axis length variable adjustable square tube machine based on press roller dislocation design

Abstract

The invention provides a four-axis length variable adjustable square tube machine based on press roller dislocation design, and belongs to the technical field of square tube machines. The device comprises a straightening device, an extrusion device and a staggered sizing device, the straightening device comprises a straightening seat, four straightening compression roller assemblies arranged in the circumferential direction are connected to the straightening seat through a position adjusting structure, a round pipe straightening channel is formed among the four straightening compression roller assemblies, and the extrusion device comprises an extrusion rack. Straightened round pipes can be extruded into square pipes after entering the extrusion forming channel formed by combining the horizontal compression roller assembly and the vertical compression roller assembly in the extrusion rack, and the horizontal compression roller assembly and the vertical compression roller assembly can be adjusted in multiple directions so that the size of the extrusion forming channel can be adjusted according to the size requirements of different square pipes. And square and rectangular square tube products are used, the die does not need to be disassembled and replaced, the production efficiency can be effectively improved, and collision damage caused when the die is disassembled and assembled can be reduced.

Description

technical field [0001] The invention belongs to the technical field of square pipe machines, and relates to a four-axis length variable adjustable square pipe machine based on the dislocation design of pressure rollers. Background technique [0002] Square tube is a name for square tube. As a cost-effective steel, it is mainly used in the field of engineering and construction, including steel structure houses, main workshops, boiler steel frames, municipal construction, and machinery manufacturing. At present, Beijing, Tianjin, Shanghai and other places have built a batch of steel structure residential pilot demonstration projects, which are pure steel systems composed of square (rectangular) pipe columns and H-shaped steel sections. more than 50% of the total. At present, square pipes are generally formed by extrusion through circular pipes, but when the square pipe machines in the prior art produce square pipes of different sizes, it is necessary to change the width and ...

AI Technical Summary

Problems solved by technology

At present, square pipes are generally formed by extrusion through circular pipes, but when the square pipe machines in the prior art produce square pipes of different sizes, it is necessary to change the width and height of the extrusion channel by changing the pressure rollers of different sizes. However, the disassembly and replacement of the pressure roller will reduce the production efficiency, and it is easy to collide during disassembly and cause the pressure roller to be damaged.
