Slight and flexible straightening device for small-diameter round tubes

Abstract

The invention discloses a slight and flexible straightening device for small-diameter round tubes. The slight and flexible straightening device for the small-diameter round tubes comprises a base and a U-shaped limiting frame, wherein the U-shaped limiting frame is arranged on the base through screws; an elastic gasket, an interface gasket and a fixed rubbing plate are sequentially arranged in the limiting frame; the elastic gasket is close to a back plate; a partition and a tube diameter limiting gasket are arranged between each of two vertical plates and the interface gasket; the partitions are close to the interface gasket; a movable rubbing plate is arranged between the two partitions; and the elastic gasket, the interface gasket, the movable rubbing plate, the partitions, the tube diameter limiting gaskets, the vertical plates of the fixed rubbing plates and the back plate are connected to one another in a pre-tightening manner through a plurality of adjusting screws and a plurality of cylindrical pins. In a straightening process of the slight and flexible straightening device, small-diameter round tube blanks are straightened gradually under the effect of elastic pressure, rolling diameters of the small-diameter round tube blanks are reduced, the size of a gap between the movable rubbing plate and the fixed rubbing plate is reduced, and influences on straightening precision due to the rigid gap are prevented effectively. The slight and flexible straightening device is simple in structure, convenient to operate, high in straightening precision and low in cost.

Description

technical field [0001] The invention belongs to a metal material round pipe straightening device, in particular to a small-diameter round pipe micro flexible 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 micro-volume flexible straightening device for a small-diameter circular ...
