Straightener for 3D round bar with multiple skew rollers

Abstract

A three-dimensional multi-slanted roller round material straightening machine, including a frame and an upper beam, a lower beam and a column arranged on the frame, the upper and lower beams include upper and lower beam frames and are assembled on the upper and lower beams A number of upper and lower roller seats and transmission devices; between the roller seat and the beam frame, there are respectively corresponding oblique straightening roller groups installed on the beam frame and each roller seat and composed of several straightening rollers; It is characterized in that there is at least one set between the upper and lower roller bases and the upper and lower beam frames, so that the straightening rollers set on the roller bases can be horizontally displaced relative to the straightening rollers set on the upper and lower beam frames. And make the straightening rollers form a transmission device arranged in a staggered arrangement or on the rollers. Because the present invention adopts the above-mentioned structural design, different straightening roller arrangements can be selected according to the material, specification and variety to be processed in the straightening process, which not only ensures the straightening accuracy of the straightened pipe and bar, but also ensures It has achieved the effect of one machine with multiple functions, thus reducing the production cost.

Description

technical field [0001] The invention relates to a metal processing equipment, in particular to a three-dimensional multi-slant roller round material straightening machine used for processing metal tubes and bars. Background technique [0002] At present, the straightening rollers of metal round material straightening machines at home and abroad are basically symmetrically arranged or staggeredly arranged, and each kind of straightening machine only adopts one arrangement; the center distance between the rollers is Cannot be adjusted. Such a structure makes each straightening equipment have certain restrictions on the straightening of the round material, or it is better for the straightening of the bar and poorer for the straightening of the pipe, and vice versa; The straightening requirements of the material and the pipe are relatively high. Take the pipe as an example: because the straightening of the pipe is affected by the thickness of the pipe wall, the required straig...
