Minor-diameter round tube micro-scale flexible straightening method and device

Abstract

The invention discloses a minor-diameter round tube micro-scale flexible straightening method and device. The minor-diameter round tube micro-scale flexible straightening device comprises a base and a U-shaped limiting frame installed on the base through screws. An elastic mat, an interposed mat and a fixed twisting plate are sequentially arranged in a frame body of the limiting frame, the elastic mat is close to a back plate, the portions between two vertical plates and the interposed mat are each provided with a partition plate and a tube diameter limiting mat, the partition plates are close to the interposed mat, and a movable twisting plate is arranged between the two partition plates. The elastic mat, the interposed mat, the movable twisting plate, the partition plates, the tube diameter limiting mats and the vertical plates of the fixed twisting plate are connected with the back plate in a pre-tightened mode through a plurality of adjustment screws and a plurality of cylindrical pins. According to the minor-diameter round tube micro-scale flexible straightening method and device, in the straightening process, under the elastic pressure, a minor-diameter round tube blank is gradually straightened, the rolling diameter is accordingly decreased, a gap between the movable twisting plate and the fixed twisting plate is accordingly decreased, influences of a rigid gap on the straightening accuracy are effectively prevented, and the minor-diameter round tube micro-scale flexible straightening device is simple in structure, convenient to operate, high in straightening accuracy and low in cost.

Description

technical field [0001] The invention belongs to a metal material round pipe straightening method and a fitting, in particular to a small-diameter round pipe micro-flexible straightening method and a straightening device. Background technique [0002] The straightness used in some industries requires relatively high straightness. The diameter of the small-diameter round tube blank is generally about 4mm. Generally, it is necessary to use rigid fixed-gap straightening equipment or manual straightening. Due to the small diameter of the tube, there is a large straightening Straight error, low production efficiency. Contents of the invention [0003] The present invention is proposed to overcome the rigid fixed gap straightening equipment or manual straightening method existing in the prior art. Due to the small diameter of the pipe, there is a large straightening error and the problem of low production efficiency. Its purpose is to provide a A small-diameter circular tube mic...
