Description

Omnipotent adjuster

The utility model relates to metal tube bar former drawbench, particularly a kind of omnipotent adjusting device that is used for metal tube bar former drawbench.

In the production of the tubing of non-ferrous metal or ferrous metal or bar, every vertical bar all is to adopt the drawbench drawing and forming.Generally speaking, the product after stretched all can produce bending, wants bent products is become straight, also must adopt equipment for straightening to align.

Fig. 1 is existing drawbench drawing and forming structural representation.Pipe bar raw material 4 passes stretching external mold 2 and clamps stretching by vice 1, produces the pipe bar of required form and specification.

In powerful drawing process, the pipe rod product produces crooked reason and roughly can be summarized as follows:

A. it is inconsistent with stretching external mold center line to draw center line BC (being the on line of the intersection points B of the force C of vice grip tube bar and stretching external mold symmetrical center line and die orifice);

B. product heats inhomogeneously in heat treatment process, makes the plasticity of metal inconsistent;

C. pipe thickness is inhomogeneous, makes its distortion inhomogeneous.

The practice explanation, control central line and stretching external mold center line are inconsistent to be maximum reason.

The pipe bar is in pulling process, because drawbench lathe bed rail level out-of-flatness, or chain movement straight line not in the lathe bed, make vice be in operation about, about the fluctuation be inevitable, thereby it is in alignment that drawing center line and external mold center line are difficult to, the two wires forms an inclination angle, and pipe has just produced bending.In addition, the stretching external mold is packed into after the stretching template, and its center line is difficult to draw center line in alignment, and the two wires certainly exists small angle, and it is crooked that this also makes pipe produce.

The purpose of this utility model is exactly in order to solve the problem of the pipe bar bending that stretches out from drawbench, drawbench is improved, a kind of omnipotent adjuster is provided, make the metal tube bar in the stretching Cold Drawing Process, keep drawing center line and external mold center line in alignment all the time, drawing the pipe bar that comes out becomes the rectilinear tubes bar that needn't align again.

Inventive concept of the present utility model is:

In view of stretching tube bar on existing drawbench produces crooked, mainly be to draw center line and the external mold center line is inconsistent causes, in order to guarantee two straight line unanimities, must make external mold in drawing process, following all the time vice transversal wave movement and together the change, no matter vice is in any one angle, any one difference all will neatly, automatically be aligned the center line of external mold and draw central lines point-blank, makes it can obtain after stretching a kind of quite straight material product.

For principle of the present utility model is described, at first let us is defined as follows:

1. fixing point A---the intersection point on the plane of cover center line and four axle formation in the hollow truncated cone body is changeless.

2. float some B---the center line of stretching external mold and the intersection point of die orifice, the AB external mold center line that promptly stretches, the locus of putting B of floating changes with the C point.

3. transfer point C---vice is clamped down on the clamp point of the material that is stretched.

Fixing point A and transfer point C constitute a straight line, we are called the drawing center line, owing to hauled motion by vice in the pipe bar pulling process, the C point is not only goed ahead in motion process, and about can producing, about the fluctuation, so the AC straight line also changes at any time in the position in space, if the motionless working condition that just forms at present general drawbench of B point, key of the present utility model just will make the B point become unsteady point, i.e. change of ordering along with C and changing is on the AC line B point all the time.So just can guarantee all the time that in pipe bar drawing process external mold center line (AB) overlaps with drawing center line (AC).
