Abstract
The utility model relates to a sleeve type shrinkage tube mould, and belongs to the technical field of shrinkage tube moulds. The sleeve type shrinkage tube mould comprises a first sleeve, and is characterized in that a second sleeve and a shrinkage tube mould body are arranged in the first sleeve from left to right in sequence. The central line of the second sleeve and the central line of the shrinkage tube mould body are at the same straight line. The shrinkage tube mould body is formed by a cone-structured shrinkage port section and a forming section, and the big end of the shrinkage port section is located on the right side of the second sleeve. The sleeve type shrinkage tube mould is simple in structure, convenient to use and easy to operate; due to the fact that the central line of the second sleeve and the central line of the shrinkage tube mould body are at the same straight line, the coaxiality for machining steel pipes is effectively guaranteed, and machining accuracy is high.
Description
Technical field
The utility model relates to a kind of telescopic pipe-reduction mold, belongs to the pipe-reduction mold technical field.
Background technology
At present, after steel pipe draw technology generally adopts special-purpose draw fixture that outer diameter of steel pipes is narrowed down to certain size, then process the endoporus of steel pipe by the method for turning.Adopt this method adding man-hour, the steel pipe axiality of processing is difficult for assurance, and precision is poor.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of telescopic pipe-reduction mold is provided, and it is simple in structure, has guaranteed the axiality of processing steel pipe during the draw.
Telescopic pipe-reduction mold described in the utility model, comprise the first sleeve, it is characterized in that: in the first sleeve inner, be disposed with from left to right the second sleeve and draw mould, the center line of the center line of the second sleeve and draw mould is on same straight line, draw mould is comprised of reducing section and the profiled section of pyramidal structure, and the large end of reducing section is positioned at the second sleeve right side.
Above-mentioned the first sleeve is mainly used in preventing that the second sleeve and the draw mould from deforming when work; The second sleeve is mainly used in the charging of steel pipe; Draw mould is mainly used in steel pipe is carried out to draw work; So, because the center line of the center line of the second sleeve and draw mould has effectively been guaranteed the axiality of processing steel pipe on same straight line, precision is higher.
When the draw is used, adopt power that steel pipe is entered from the second sleeve left end, then carry out draw work by the reducing section, and steel pipe is moved to concordant with draw mould right-hand member, finally from draw mould right-hand member, exit left, thereby completed the draw work of steel pipe, can carry out further work.
In order further to improve result of use of the present utility model, the large port footpath of preferred described reducing section is greater than the cylinder internal diameter of the second sleeve.When the draw, steel pipe is easy to enter from the large end of reducing section, thereby completes smoothly the draw work of steel pipe.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, easy to use, simple to operate, so, because the center line of the center line of the second sleeve and draw mould has effectively been guaranteed the axiality of processing steel pipe on same straight line, precision is higher.
The accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
In figure: 1, the first sleeve 2, the second sleeve 3, draw mould 3.1, profiled section 3.2, reducing section.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail; but not in order to limit the utility model; all within the utility model spirit and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
As shown in Figure 1, telescopic pipe-reduction mold, comprise the first sleeve 1, be disposed with from left to right the second sleeve 2 and draw mould 3 in the first sleeve 1 inside, the center line of the center line of the second sleeve 2 and draw mould 3 is on same straight line, draw mould 3 is comprised of reducing section 3.2 and the profiled section 3.1 of pyramidal structure, and the large end of reducing section 3.2 is positioned at the second sleeve 2 right sides.
In the present embodiment, the large port footpath of described reducing section 3.2 is greater than the cylinder internal diameter of the second sleeve 2.
When the draw is used, adopt power that steel pipe is entered from the second sleeve 2 left ends, then carry out draw work by reducing section 3.2, and steel pipe movement is extremely concordant with draw mould 3 right-hand members, finally from profiled section 3.1 right-hand members, exit left, thereby completed the draw work of steel pipe, can carry out further work.
Claims (2)
