Abstract

The utility model discloses a hyperbolic roll on a cold pilgering mill. The hyperbolic roll comprises two symmetrically arranged groove blocks (1), wherein rolled tube grooves (2) are arranged on the periphery of each groove block (1), and the section of each rolled tube groove (2) is hyperbola-shaped. The hyperbolic roll enables organization crystal grain of cold-rolled pipes to be precise, mechanical property of the cold-rolled pipes to be fine, geometric dimension of the cold-rolled pipes to be accurate and surface smoothness of the cold-rolled pipes to be further improved, and has excellent use effect.

Description

Hyperbola roll on the cold pilger mill
Technical field
The utility model relates to the hyperbola roll on a kind of cold pilger mill, relates to the manufacturing technology of stainless-steel pipe.
Background technology
The roll of traditional two-high cold-rolling pipe mill adopts taper tube rolling groove; This concave roll is when rolling pipe, and roller surface and pipe are circular arc and the contacting of straight line, and distortion is concentrated; The load that pipe bears is bigger; Make the steel pipe tubing after cold rolling organize crystal grain coarse, the physical dimension error is bigger, and the mechanical property of tubing is more undesirable; Simultaneously, correspondingly the load that receives of roll is also bigger, and the roller surface wearing and tearing are very fast, so the service life of roll is shorter.
The utility model content
The purpose of the utility model is, the roll of the hyperbola on a kind of cold pilger mill is provided.What the utility model made cold rolling back tubing organizes crystal grain more fine and closely woven, and mechanical properties of tubular goods is more good, and geometric accuracy is more accurate, and surface smoothness further improves, and has very superior result of use.
The technical scheme of the utility model: the hyperbola roll on the cold pilger mill, comprise symmetrically arranged two groove pieces, offer the tube rolling hole on the circumference of described groove piece, the cross section in two tube rolling holes be shaped as hyperbola.
In the hyperbola roll on the above-mentioned cold pilger mill, described groove piece is a cylindrical shape.
Compared with prior art, the cross sectional shape of the tube rolling groove of the utility model is a hyperbola, compares with common taper tube seat; Adding man-hour hyperbola roll is circular arc and the contacting of circular arc with contacting of pipe, makes pipe receive the power of rolling and evenly disperse that the steel pipe tubing after cold rolling organizes crystal grain more fine and closely woven; Mechanical properties of tubular goods is more good; Geometric accuracy is more accurate, and surface smoothness further improves, and has very superior result of use.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model;
Fig. 2 is the sectional view of the utility model.
Being labeled as in the accompanying drawing: 1-groove piece, 2-tube rolling groove, 3-steel pipe pipe.
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.Hyperbola roll on a kind of cold pilger mill, as attach illustrated in figures 1 and 2ly comprises symmetrically arranged two groove pieces 1, offers tube rolling groove 2 on the circumference of groove piece 1, the cross section of described tube rolling groove 2 be shaped as hyperbola.Preferably, described groove piece 1 is a cylindrical shape.
Operation principle: upper and lower two groove pieces are symmetrical set; And synchronous backwards rotation under the driving of toggle; Steel pipe pipe 3 is fixed on the plug; Plug moves axially on workbench under the driving of revolution and feed mechanism back and forth, and plug drives the steel pipe pipe and passes the cold rolling processing of two groove interblock realization steel pipe pipes up and down.The cross sectional shape of the tube rolling groove of the utility model is a hyperbola, compares with common taper tube seat, and adding man-hour hyperbola roll is circular arc and the contacting of circular arc with contacting of pipe; Making pipe receive the power of rolling evenly disperses; Steel pipe tubing after cold rolling organizes crystal grain more fine and closely woven, and mechanical properties of tubular goods is more good, and geometric accuracy is more accurate; Surface smoothness further improves, and has very superior result of use.
