Abstract
The utility model provides a kind of two cold rolling mould of roller, and it includes and is assemblied in corresponding rolling on seat and the pressed on ring pattern cooperatively interacted, lower ring-like mould, adjacent with the outer shroud top of lower ring-like mould bottom the outer shroud of described pressed on ring pattern; The outer shroud of pressed on ring pattern, lower ring-like mould circumferentially indent is formed with special-shaped annular groove, and the special-shaped annular groove being positioned at pressed on ring pattern and lower ring-like mould adjacent regions is combined to form circular extruded hole; The lateral wall of pressed on ring pattern, lower ring-like mould adjacent regions is provided with the U-lag be interconnected; The ring body sidewall of pressed on ring pattern, lower ring-like mould is provided with counterbore.Mould of the present utility model can be directly applied for existing pair of roller cold pilger mill, directly can shut out production tube by special-shaped annular groove; Adopt this programme can greatly reduce production and processing cost, effectively improve quality and the production efficiency of product.
Description
Technical field
The utility model relates to cold rollingly touches technical field, especially a kind of two cold rolling mould of roller.
Background technology
Special pipe is the chief component in metal tube kind, and in industrial and agricultural production and other every economic activities, all have a large amount of use, it has special effect to suitable application area, and various heterotype tubing obtains and develops rapidly in recent years; Current heterotype tubing mainly applies cold-drawing process and multiple roll cold-rolling practice is produced, and these method rolling passes are many, and deformation coefficient is little, limits its scope of application, makes the high-quality that many market in urgent needs are wanted, and high-accuracy shaped pipe cannot be produced in a large number.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure simple, the cold rolling effective cold rolling mould of two rollers.
For achieving the above object, technical scheme provided by the utility model is: a kind of two cold rolling mould of roller, it includes and is assemblied in corresponding rolling on seat and the pressed on ring pattern cooperatively interacted, lower ring-like mould, adjacent with the outer shroud top of lower ring-like mould bottom the outer shroud of described pressed on ring pattern; The outer shroud of pressed on ring pattern, lower ring-like mould circumferentially indent is formed with special-shaped annular groove, and the special-shaped annular groove being positioned at pressed on ring pattern and lower ring-like mould adjacent regions is combined to form circular extruded hole; The lateral wall of pressed on ring pattern, lower ring-like mould adjacent regions is provided with the U-lag be interconnected; The ring body sidewall of pressed on ring pattern, lower ring-like mould is provided with counterbore.
Described counterbore is positioned on the contrary sidewall of pressed on ring pattern, lower ring-like mould.
The arc corner cut of the equal concavity of outer ring surface edge of described pressed on ring pattern, lower ring-like mould.
Described special-shaped annular groove by car circumferentially and the semi-circular groove that diameter constantly changes form, rolling section end be provided with the constant expansion section of one section of diameter.
Mould of the present utility model can be directly applied for existing pair of roller cold pilger mill, directly can shut out production tube by special-shaped annular groove; Adopt this programme can greatly reduce production and processing cost, effectively improve quality and the production efficiency of product.

Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, the cold rolling mould of two rollers described in the present embodiment includes and is assemblied in corresponding rolling on seat and the pressed on ring pattern 1 cooperatively interacted, lower ring-like mould 2, adjacent with the outer shroud top of lower ring-like mould 2 bottom the outer shroud of described pressed on ring pattern 1; The outer shroud of pressed on ring pattern 1, lower ring-like mould 2 circumferentially indent is formed with special-shaped annular groove 3, and the special-shaped annular groove 3 being positioned at pressed on ring pattern 1 and lower ring-like mould 2 adjacent regions is combined to form circular extruded hole 4; The special-shaped annular groove 3 of the present embodiment by car circumferentially and the semi-circular groove that diameter constantly changes form, rolling section end be provided with the constant expansion section of one section of diameter.The lateral wall of pressed on ring pattern 1, lower ring-like mould 2 adjacent regions is provided with the U-lag 5 be interconnected; The ring body sidewall of pressed on ring pattern 1, lower ring-like mould 2 is provided with counterbore 8; Counterbore 8 is positioned on the contrary sidewall of pressed on ring pattern 1, lower ring-like mould 2.The arc corner cut 7 of the equal concavity of outer ring surface edge of pressed on ring pattern 1, lower ring-like mould 2.During work, time near machine frame movement to rear extreme position, materials in the tube send to feed m1 simultaneously materials in the tube rotate an angle of revolution together with plug.Work housing moves forward pattern and rolls across in materials in the tube, is in the annular gap that pass on pattern external diameter of materials in the tube between work housing two extreme positions and plug form and is out of shape.Time near machine frame movement to front extreme position, materials in the tube send to feed m2 simultaneously materials in the tube rotate an angle of revolution A together with plug.Then work housing oppositely moves to rear extreme position, repeats appeal process.This mould can be directly applied for existing pair of roller cold pilger mill, directly can shut out production tube by special-shaped annular groove; Adopt this programme can greatly reduce production and processing cost, effectively improve quality and the production efficiency of product.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
