Said punch-head assembly has two groups at least, is arranged at outside the workbench, and punch-head assembly comprises base and drift, and drift is movably set on the base.
Said drift is taper, and the diameter of drift increases along workbench clockwise or counterclockwise successively.
Said die assembly comprises upper die and lower die, and patrix is positioned under the top cover, and counterdie is arranged on the workbench, forms die cavity between the upper die and lower die, and drift is aimed at die cavity.
Be provided with compact heap between said patrix and the top cover, compact heap is in order to the patrix of filling die assembly and the space between the top cover, and compact heap is an adjustable height, and regulating compact heap can be from mold removal assembly on the workbench.
A kind of deformation processing method of tubular workpiece adopts the deformation processing device of tubular workpiece of the present invention, may further comprise the steps:
(1) be positioned between the upper die and lower die after the preformed with tubular workpiece, matched moulds utilizes top cover to compress upper die and lower die;
(2) rotary table according to punch diameter from small to large, inserts the inwall of tubular workpiece with each drift successively, and the tubular workpiece progressive deformation makes the shape that acquisition needs on the outer wall of tubular workpiece;
(3) tubular workpiece of machine-shaping is taken out in die sinking
Beneficial effect: the present invention compares prior art and has the following advantages: the present invention can realize tubular workpiece is carried out progressive moulding, has accomplished forming process, high efficiency when workbench turns around; The device overall weight is light, and the moment of torsion of transmission is big; The present invention is the cold conditions forming technique, does not heat, and does not have oxide skin and decarburized layer, does not have thermal deformation, and the product precision is higher; The multistation progressive molding, plastic force is little, and die life is high; Equipment of the present invention is littler than general multistation machine floor space, is easy to die change.
Description of drawings

Fig. 2 is the vertical view of the deformation processing device of tubular workpiece of the present invention.
The specific embodiment
Elaborate in the face of embodiments of the invention down, present embodiment provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.
As depicted in figs. 1 and 2, present embodiment comprises workbench 1, punch-head assembly 2, die assembly 3 and top cover 4; Die assembly 3 has six groups in the present embodiment, evenly is arranged on the workbench 1, and the angle of adjacent molds assembly 3 is 60 degree; Top cover 4 is arranged at the top of die assembly 3; Punch-head assembly 2 is corresponding with the position of die assembly 3; The workbench 1 of present embodiment is a rotary table, drives workbench 1 rotation at the center of workbench 1 through rotating shaft.
The punch-head assembly 2 of present embodiment has five groups, is arranged at outside the workbench 1, and punch-head assembly 2 comprises base 5 and drift 6, and drift 6 is movably set on the base 5; Drift 6 is taper, and the diameter of drift 6 increases along workbench 1 clockwise direction successively.
Die assembly 3 comprises patrix 7 and counterdie 8, and patrix 7 is positioned under the top cover 4, and counterdie 8 is arranged on the workbench 1, forms die cavity between patrix 7 and the counterdie 8, and drift 6 is aimed at die cavity, and top cover 4 is pressed on the patrix 7 during work.Patrix 7 is provided with the shape that tubular workpiece need be processed, and also can on counterdie 8, be provided with among other embodiment, and the purpose of present embodiment is that tubular workpiece is processed into tooth bar, promptly on the patrix 7 profile of tooth is set.
Be provided with compact heap 9 between patrix 7 and the top cover 4, compact heap 9 is in order to the patrix 7 of filling die assembly 3 and the space between the top cover 4, and compact heap 9 is an adjustable height, regulates compact heap 9 and can take off mould 8 die assemblies 3 from workbench 1.
Because main moulding is on the outer wall of workpiece; Moulding finishes the profile of tooth interlocking of back mould and workpiece, and not die sinking can't be taken out workpiece, and present embodiment punch-head assembly 2 lacks one than die assembly 3; Can realize when five drifts 6 all in the die cavity of die assembly 3 during to the tubular workpiece extrusion modling; Still have a die assembly 3 to be in the room, adjustment compact heap 9 just can die sinking, the workpiece that processes in the taking-up mould.
