Abstract
The utility model discloses a crystal steel pipe drawing die, which comprises a drawing die main body (1), wherein the drawing die main body (1) is partitioned into a steel pipe inlet part (2), a calibrating straight (3) and a steel pipe outlet part (4) from left to right; and the drawing die main body (1) is made of crystal. Due to the adoption of the crystal steel pipe drawing die, the straightness and size accuracy of a finished steel pipe can be increased effectively, the surface is clean, fine and attractive, and safe use of workers is ensured.
Description
Technical field
The utility model relates to a kind of drawing die that steel pipe is used of producing, particularly a kind of drawing die that adopts crystal material to make.
Background technology
Existing stainless-steel pipe generally adopts draw-off gear to process, and drawing die is a critical piece of realizing steel pipe drawing in the draw-off gear, and it is directly connected to the mechanical performance of surface quality, energy resource consumption, production operational availability and the fished pipe of steel pipe.Existing steel pipe drawing mould generally adopts the carbide alloy manufacturing; The steel pipe drawing mould of carbide alloy system mainly exists following problem: (1) is because the restriction of the processing technology of the steel pipe drawing mould of carbide alloy system; The calibrating strap of this drawing die is general short partially; Therefore the steel pipe after the drawing is directly spent and can not get guaranteeing, and is not easy to the later stage aligning; (2) high temperature that produces because of process of tube plug drawing mill easily of the drawing die of the carbide alloy system phenomenon of expanding with heat and contract with cold has influenced the machining accuracy of product; (3) surface smoothness is more coarse, and is neither attractive in appearance, also influences workman's safe handling.
The utility model content
The purpose of the utility model is, a kind of quartzy system steel pipe drawing mould is provided.The utility model can improve the steel pipe of finished product effectively directly spends and dimensional accuracy, and any surface finish is fine and smooth, the safe handling that guarantees the workman again promptly attractive in appearance.
The technical scheme of the utility model: quartzy system steel pipe drawing mould, comprise the drawing die main body, the drawing die main body is respectively steel pipe inlet portion, calibrating strap and steel pipe export department from left to right; Described drawing die main body is the drawing die main body of being processed by crystal.
In the above-mentioned crystal system steel pipe drawing mould, being shaped as of described steel pipe inlet portion is horn-like, described calibrating strap be shaped as straight tube-like, being shaped as of described steel pipe export department is cone-shaped.
Compared with prior art, the drawing die main body of the utility model is compared with the steel pipe drawing mould of carbide alloy system by the crystal manufacturing; The work zone of the utility model is longer than carbide alloy drawing die; Improve the steel pipe behind the draw and directly spent, reduced the flexibility after the heat treatment, be convenient to the aligning in later stage; Secondly, the utility model is the not influence of susceptible in process of tube plug drawing mill, has reduced the degree of expanding with heat and contract with cold, and makes that the accuracy error of processing back steel pipe is littler; The phenomenon that the 3rd quartzy system drawing die has avoided the longer draw power in carbide alloy system drawing die work zone to increase, the balance of assurance power transmission; Last the utility model any surface finish is fine and smooth, the safe handling that guarantees the workman again promptly attractive in appearance.In addition, being shaped as of the steel pipe inlet portion of the utility model is horn-like, makes things convenient for steel pipe steadily to import; Described calibrating strap be shaped as straight tube-like, the effect of calibrating strap is after making the steel pipe draw external diameter accurately to be arranged, and plays sizing; Being shaped as of described steel pipe export department is cone-shaped, makes things convenient for the disengaging of steel pipe and drawing die main body.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model.
Being labeled as in the accompanying drawing: 1-drawing die main body, 2-steel pipe inlet portion, 3-calibrating strap, 4-steel pipe export department.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but not as the restriction to the utility model.
The embodiment of the utility model.A kind of quartzy system steel pipe drawing mould constitutes as shown in Figure 1ly, comprises drawing die main body 1, and drawing die main body 1 is respectively steel pipe inlet portion 2, calibrating strap 3 and steel pipe export department 4 from left to right; Described drawing die main body 1 is the drawing die main body of being processed by crystal; Being shaped as of described steel pipe inlet portion 2 is horn-like, described calibrating strap 3 be shaped as straight tube-like, being shaped as of described steel pipe export department 4 is cone-shaped.The drawing die main body of the utility model is by the crystal manufacturing; Compare with the steel pipe drawing mould of carbide alloy system, the work zone of the utility model is longer than carbide alloy drawing die, has improved the steel pipe behind the draw and has directly spent; Reduce the flexibility after the heat treatment, be convenient to the aligning in later stage; Secondly, the utility model is the not influence of susceptible in process of tube plug drawing mill, has reduced the degree of expanding with heat and contract with cold, and makes that the accuracy error of processing back steel pipe is littler; The phenomenon that the 3rd quartzy system drawing die has avoided the longer draw power in carbide alloy system drawing die work zone to increase, the balance of assurance power transmission; Last the utility model any surface finish is fine and smooth, the safe handling that guarantees the workman again promptly attractive in appearance.In addition, being shaped as of the steel pipe inlet portion of the utility model is horn-like, makes things convenient for steel pipe steadily to import; Described calibrating strap be shaped as straight tube-like, the effect of calibrating strap is after making the steel pipe draw external diameter accurately to be arranged, and plays sizing; Being shaped as of described steel pipe export department is cone-shaped, makes things convenient for the disengaging of steel pipe and drawing die main body.
Claims (2)
1. quartzy system steel pipe drawing mould, it is characterized in that: comprise drawing die main body (1), drawing die main body (1) is respectively steel pipe inlet portion (2), calibrating strap (3) and steel pipe export department (4) from left to right; Described drawing die main body (1) is the drawing die main body of being processed by crystal.
