Technical scheme: the present invention is achieved by the following technical solutions, the present invention includes workbench, punch-head assembly, die assembly and top cover; Described die assembly has two groups at least, is arranged at respectively on workbench; Top cover is arranged at the top of die assembly; The position of punch-head assembly and die assembly is corresponding; Described workbench is rotary table.
Described punch-head assembly has two groups at least, is arranged at outside workbench, and punch-head assembly comprises base and drift, and drift is movably set on base.
Described drift is taper, and the diameter of drift increases clockwise or counterclockwise successively along workbench.
Described die assembly comprises upper die and lower die, and patrix is positioned under top cover, and counterdie is arranged on workbench, forms die cavity between upper die and lower die, and drift is aimed at die cavity.
Between described patrix and top cover, be provided with compact heap, compact heap is in order to fill the patrix of die assembly and the space between top cover, and compact heap is adjustable height, regulate compact heap can be from workbench mold removal assembly.
A deformation processing method for tubular workpiece, adopts the deformation processing device of tubular workpiece of the present invention, comprises the following steps:
(1) will after the preformed of tubular workpiece, be positioned between upper die and lower die, matched moulds, utilizes top cover to compress upper die and lower die;
(2) rotary table, according to punch diameter from small to large, inserts each drift the inwall of tubular workpiece successively, and tubular workpiece progressive deformation makes to obtain on the outer wall of tubular workpiece the shape needing;
(3) die sinking, takes out the tubular workpiece of machine-shaping
Beneficial effect: the present invention has the following advantages compared to existing technology: the present invention can realize tubular workpiece is carried out to progressive moulding, has completed forming process when workbench turns around, and operating efficiency is high; Device overall weight is light, and the moment of torsion of transmission is large; The present invention is cold conditions forming technique, does not heat, and there is no oxide skin and decarburized layer, there is no thermal deformation, and Product Precision is higher; Multistation progressive molding, plastic force is little, and die life is high; Equipment of the present invention is less than general multistation machine floor space, is easy to die change.
Accompanying drawing explanation
Fig. 1 is the front view of the deformation processing device of tubular workpiece of the present invention;
Fig. 2 is the top view of the deformation processing device of tubular workpiece of the present invention.
The specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, the present embodiment comprises workbench 1, punch-head assembly 2, die assembly 3 and top cover 4; In the present embodiment, die assembly 3 has six groups, is evenly arranged on 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 the present embodiment is rotary table, at the center of workbench 1, by rotating shaft, drives workbench 1 rotation.
The punch-head assembly 2 of the present embodiment has five groups, is arranged at outside workbench 1, and punch-head assembly 2 comprises base 5 and drift 6, and drift 6 is movably set on base 5; Drift 6 is taper, and the diameter of drift 6 increases clockwise successively along workbench 1.
Die assembly 3 comprises patrix 7 and counterdie 8, and patrix 7 is positioned under top cover 4, and counterdie 8 is arranged on workbench 1, between patrix 7 and counterdie 8, forms die cavity, and drift 6 is aimed at die cavity, and during work, top cover 4 is pressed on patrix 7.Patrix 7 is provided with the shape that tubular workpiece need to be processed, and in other embodiment, also can on counterdie 8, arrange, and the object of the present embodiment is that tubular workpiece is processed into tooth bar, on patrix 7, profile of tooth is set.
Between patrix 7 and top cover 4, be provided with compact heap 9, compact heap 9 is in order to fill the patrix 7 of die assembly 3 and the space between top cover 4, and compact heap 9 is adjustable height, regulates compact heap 9 to 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 rear mold and workpiece, not die sinking cannot be taken out workpiece, few one than die assembly 3 of the present embodiment punch-head assembly 2, can realize when five drifts 6 are all in the die cavity of die assembly 3 during to tubular workpiece extrusion modling, still have a die assembly 3 in room, adjusting compact heap 9 just can die sinking, the workpiece processing in taking-up mould.
The method of using this device processing tubular workpiece, comprises the following steps:
(1) will after the preformed of tubular workpiece, be positioned between patrix 7 and counterdie 8, matched moulds, utilizes top cover 4 to compress patrix 7 and counterdie 8, and flatten a little at the tubular workpiece top after preformed, facilitates mould compressing;
(2) rotary table 1, according to drift 6 diameters from small to large, in the direction of the clock each drift 6 inserted in the pipe of each tubular workpiece successively, then extracts progressive moulding;
(3) after rotating a circle, the die assembly 3 with the workpiece of moulding is moved to room, i.e. loading and unloading station, does not have the position of drift 6 exactly, and compact heap 9 releases, open mould, take out workpiece; Or drift 6 returns, adjust compact heap 9, take out workpiece, the top of workpiece now processes required profile of tooth.
