Circular-section solid metal wire reduced-diameter compression roll

Abstract

The invention discloses a circular-section solid metal wire reduced-diameter compression roll, which comprises a plurality of compression roll groups and a plurality of horizontal compression roll groups, wherein each vertical compression roll consists of two vertical compression rolls relatively arranged in the vertical direction, each horizontal compression roll consists of two horizontal compression rolls oppositely arranged in the horizontal direction, an extrusion groove is formed in an extrusion surface between the two vertical compression rolls, an extrusion groove is formed in an extrusion surface between the two horizontal compression rolls, the cross section of the extrusion groove is arc-shaped with the radian of 30-120degrees, the extrusion groove is formed in the center of the extrusion surface, and a fillet is formed between the extrusion groove and the extrusion surface. The circular-section solid metal wire reduced-diameter compression roll has the advantages and positive effects that a roll caliber is designed and optimized according to the circular-section solid metal wire reduced-diameter compression change trend, the torsion of the wire is limited, and the deformation space of the wire can be reasonably controlled; the processing and manufacturing are simple and practical, the deflects of reduced-diameter compression of the circular-section solid metal wire can be easily and reliably solved, and the shape surging of the wire can be effectively relieved.

Description

technical field [0001] The invention belongs to the field of metal wire rod diameter reduction equipment, and in particular relates to a circular section solid metal wire rod diameter reduction compression roller. Background technique [0002] In the rolling and drawing process of circular cross-section metal solid wire rods, it is necessary to use a reducer to reduce the diameter of the wire rods. The principle is to use two interacting rollers to squeeze the wire rods, but the existing technology In the process, due to the unreasonable pass design of the pressure roller, the wire often has problems such as torsion, irregular cross-sectional shape or rough surface. Contents of the invention [0003] The problem to be solved by the present invention is to provide a diameter-reducing compression roller for a solid metal wire with a circular cross-section, which can solve the above-mentioned problems. [0004] In order to solve the above-mentioned technical problems, the te...
