Abstract

The invention relates to a sleeve type pipe shrinking die, and belongs to the technical field of pipe shrinking dies. The sleeve type pipe shrinking die comprises a first sleeve. A second sleeve and a pipe shrinking die body are sequentially arranged in the first sleeve from left to right. The center line of the second sleeve and the center line of the pipe shrinking die body are located on the same straight line. The pipe shrinking die body is composed of a necking segment of a conical structure and a forming segment. The large end of the necking segment is located on the right side of the second sleeve. The second sleeve and the first sleeve are fixed through first screws. The first screws are located from the outer side wall of the first sleeve to the wall thickness of the second sleeve. The pipe shrinking die body and the first sleeve are fixed through second screws. The second screws are located from the outer side wall of the first sleeve to the wall thickness of the pipe shrinking die body. By means of the sleeve type pipe shrinking die, the sleeve type pipe shrinking die is simple in structure, and the second sleeve and the pipe shrinking die body can be replaced according to different specifications during use, so that production cost is effectively reduced.

Description

Telescopic pipe-reduction mold
Technical field
The present invention relates to a kind of telescopic pipe-reduction mold, belong to pipe-reduction mold technical field.
Background technology
At present, after steel pipe draw technology generally adopts special draw fixture that outer diameter of steel pipes is narrowed down to certain size, then the endoporus of steel pipe is processed by the method for turning.Adopt and adding man-hour in this way, the steel pipe axiality of processing not easily ensures, precision is poor.
Inventor has devised a kind of telescopic pipe-reduction mold for this reason, comprise the first sleeve, it is characterized in that: be disposed with the second sleeve and draw mould from left to right in the first sleeve inner, the center line of the second sleeve and the center line of draw mould are on the same line, draw mould is made up of the reducing section of pyramidal structure and profiled section, and the large end of reducing section is positioned on the right side of the second sleeve.In use, the second sleeve and draw mould weld, if just waste mould when changing specification with fixing often employing of the first sleeve.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of telescopic pipe-reduction mold, and its structure is simple, in use can according to specification not changing the second sleeve and draw mould, the production cost effectively saved.
Telescopic pipe-reduction mold of the present invention, comprise the first sleeve, the second sleeve and draw mould is disposed with from left to right in the first sleeve inner, the center line of the second sleeve and the center line of draw mould are on the same line, draw mould is made up of the reducing section of pyramidal structure and profiled section, the large end of reducing section is positioned on the right side of the second sleeve, it is characterized in that: the second sleeve is fixed by the first screw and the first sleeve, first screw by the first sleeve lateral wall on the wall thickness of the second sleeve, draw mould is fixed by the second screw and the first sleeve, second screw by the first sleeve lateral wall on the wall thickness of draw mould.
In order to improve result of use of the present invention further, 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, thus completes the draw work of steel pipe smoothly.
The beneficial effect that the present invention has is:
By the present invention, its structure is simple, in use can according to specification not changing the second sleeve and draw mould, the production cost effectively saved.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
In figure: 1, the first sleeve 2, second sleeve 3, draw mould 3.1, profiled section 3.2, reducing section 4, first screw 5, second screw.
Detailed description of the invention
Below by way of specific embodiment, the invention will be further described, but not in order to limit the present invention, all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
As shown in Figure 1, telescopic pipe-reduction mold, comprise the first sleeve 1, the second sleeve 2 and draw mould 3 is disposed with from left to right in the first sleeve 1 inside, the center line of the second sleeve 2 and the center line of draw mould 3 are on the same line, draw mould 3 is made up of the reducing section 3.2 of pyramidal structure and profiled section 3.1, the large end of reducing section 3.2 is positioned on the right side of the second sleeve 2, second sleeve 2 is fixed by the first screw 4 and the first sleeve 1, first screw 4 by the first sleeve 1 lateral wall on the wall thickness of the second sleeve 2, draw mould 3 is fixed by the second screw 5 and the first sleeve 1, second screw 5 by the first sleeve 1 lateral wall on the wall thickness of draw mould 3.
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 uses, adopt power to be entered from the second sleeve 2 left end by steel pipe, then carry out draw work by reducing section 3.2, and by steel pipe movement to concordant with draw mould 3 right-hand member, finally exit left from profiled section 3.1 right-hand member, thus complete the draw work of steel pipe, can further work be carried out.
