Two-roller cold rolling mill structure for copper rod

Abstract

The invention provides a two-roller cold rolling mill structure for a copper rod. By using the two-roller cold rolling mill structure, the problem that trimming and crackling phenomena are easily generated in the rolling process of the copper rod by using the existing two-roller cold rolling mill structure for the copper rod can be solved, meanwhile, the problem of scratching the surface of the copper rod in the rolling process can be solved, and the machining quality is ensured. The two-roller cold rolling mill structure for the copper rod comprises a rack, a pair of roller devices and guide devices, wherein two rollers of the pair of roller devices are symmetrically arranged in the rack; the guide devices are set into two groups; the two groups of guide devices are symmetrically arranged at a copper rod inlet and a copper rod outlet of the rack; guide grooves are formed in the guide devices; roller half-grooves are formed in the peripheral surfaces of the rollers; and the two roller half-grooves of the two rollers are spliced to form a circumference-closed roller groove when two symmetric rollers are used for rolling the copper rod. The two-roller cold rolling mill structure for the copper rod is characterized in that the guide grooves and the roller groove are polygonal grooves which are same in shape and are axisymmetric.

Description

Technical field [0001] The invention relates to the field of cold rolling production equipment for copper rods, in particular to the structure of a two-roll copper rod cold rolling mill. Background technique [0002] Two-roll copper rod cold rolling mill is usually used for continuous multi-pass cold rolling processing of copper rods. It has the characteristics of high efficiency, energy saving, refinement and strengthening of the crystal structure of copper rods. It is ideal for up-drawing oxygen-free copper rod continuous casting production lines Back-end supporting equipment. Generally, a two-high copper rod cold rolling mill completes the rolling of copper rods through multiple sets of vertical rolling and cross rolling in turn. A pair of rolls are installed on the stand of each set of vertical or cross rolling units, taking the vertical rolling unit as an example ,see figure 1 , A pair of rolls 2 are installed on the frame 1 symmetrically up and down. A set of guide devices...
