Abstract
The utility model discloses a self -align centre form that moves about of steel pipe cold drawing mould, the self -align centre form that moves about of the aforesaid follow the axial and set gradually to the preceding cylindrical section that is used for direction and installation, the round conic section that the internal diameter change was passed through when being used for making the steel pipe shaping and the back cylindrical section that is used for confirming the steel pipe internal diameter, back cylindrical section is provided with and is used for making the steel pipe metal to receive the cutting of a fixed directive effect power, the recessed setting of cutting is being close to circle conic section's position department. The utility model discloses an in the self -align centre form sizing position front end cutting of moving about, the metal flows between centre form and external mold during the steel pipe cold drawing, because centre form cutting metal receives the power of a fixed orientation when external here to make the centre form not move about around no longer during at the draw at the back -and -forth movement centre form, steel pipe wall thickness difference end to end is different within 3.
Description
Technical field
This utility model is related to steel pipe forming field, and in particular to the self-positioning travelling internal model of Tube Drawing mould.
Background technology
For in pressing direction in pressed compact or the part of the mould of sintered body internal shaping contoured surface, with station boiler temperature
Degree, the continuous improvement of pressure, put forward higher requirement to the interior table quality and dimensional accuracy of cold drawing steel tube, current high requirement
Drawn tube typically produced by the way of lining core draw.It is not high using mass color cleanliness in common internal model cold drawing steel tube, using certainly
The travelling internal model of positioning can improve interior table quality, but because internal model is not fixed position in draw, according to stress difference during cold-drawn
Move about before and after generation so that steel pipe head and tail wall thickness there are about 10 differences.
The content of the invention
To solve above-mentioned technical problem, goal of the invention of the present utility model is to provide a kind of reduction move about before and after internal model
The self-positioning travelling internal model of Tube Drawing mould.
For achieving the above object, this utility model provides following technical scheme：A kind of Tube Drawing mould from
The travelling internal model of positioning, it is front cylindrical section for being oriented to and installing that the self-positioning travelling internal model sets gradually vertically, be used for
The conical section and the rear cylindrical section for determining pipe diameter of internal diameter change transition when making steel pipe forming, the rear cylindrical section is arranged
There is the cutting for making steel pipe metal be subject to a fixed-direction active force, the cutting is recessed to be positioned close to the conical section
Position at.
In above-mentioned technical proposal, the cutting is prolonged in annular shape, the cutting along the ring of the self-positioning travelling internal model
Stretch.
In above-mentioned technical proposal, the cutting is in arc-shaped, ring of multiple cuttings along the self-positioning travelling internal model
Arrange to spacing distance.
In above-mentioned technical proposal, the rear cylindrical section is additionally provided with the inverted cone segment for increasing with the contact area of steel pipe,
The inverted cone segment arranges the free end position of cylindrical section in the rear.
In above-mentioned technical proposal, the length of the cutting is in the range of 0.5 centimetre ~ 1 centimetre.
In above-mentioned technical proposal, the depth of the cutting is in the range of 8 ~ 12.
In above-mentioned technical proposal, the width of the cutting is in the range of 1 ~ 5.
Because above-mentioned technical proposal is used, this utility model has compared with prior art following advantages：This utility model
By the way that in self-positioning travelling internal model sizing position front end cutting, metal flows between internal model and external mold during Tube Drawing, by
By the power of a fixed-direction when internal model cutting metal here is external, so that internal model is not in movable internal model in draw
Move about before and after Shi Buzai, steel pipe head and tail wall thickness difference is within 3.
Description of the drawings
Fig. 1 is the structural representation of self-positioning travelling internal model disclosed in this utility model
Fig. 2 is the partial enlarged drawing of cutting disclosed in this utility model.
Wherein, 10, front cylindrical section；20th, conical section；30th, rear cylindrical section；40th, cutting；50th, inverted cone segment.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate this utility model, but is not limited to scope of the present utility model.
Referring to Fig. 1 and Fig. 2, as shown in legend therein, a kind of self-positioning travelling internal model of Tube Drawing mould, this is made by oneself
It is front cylindrical section 10 for being oriented to and installing that the travelling internal model in position sets gradually vertically, for making internal diameter change during steel pipe forming
The conical section 20 of transition and the rear cylindrical section 30 for determining pipe diameter, rear cylindrical section 30 is provided with for receiving steel pipe metal
To the cutting 40 of a fixed-direction active force, cutting 40 is recessed to be positioned close at the position of conical section 20.
Wherein, cutting 40 is in annular shape, circumferentially extending, the length of cutting 40 of the cutting 40 along the self-positioning travelling internal model
In 1cm, depth about 10, width 1-5 silks.
Steel pipe in cold-drawn metal in internal model（Self-positioning travelling internal model）Flow and external mold between, metal is in cutting 40
By the power of a fixed-direction when putting, so that self-positioning travelling internal model is no longer moved forward and backward.
Front cylindrical section：Internal model sizing section and changeover portion are reinforced, while playing interconnection function；
Conical section：Pipe diameter hypermetamorphosis region；
Cylindrical section afterwards：Determine pipe diameter；
Cutting：Metal flows between internal model and external mold during Tube Drawing, due to internal model cutting metal here it is external when
By the power of a fixed-direction, so that internal model is not movable
In order to increase internal model and steel pipe contact area, increase frictional force, rear cylindrical section 30 also sets up inverted cone segment 50, inverted cone segment
The 50 free end positions for being arranged on rear cylindrical section 50.
Embodiment two
Remaining is identical with embodiment one, and difference is, above-mentioned cutting is in arc-shaped, multiple above-mentioned cuttings along it is above-mentioned from
