Abstract
The invention discloses a cold-extrusion sealed forming mould. The cold-extrusion sealed forming mould comprises an upper forming mould and a lower forming mould, wherein a tool containing concave part and a thimble through hole which are communicated with each other are formed in the middle of the lower forming mould; the tool containing concave part is located above the thimble through hole; the thimble through hole is provided with a thimble capable of being moved up and down; a product film forming pressing part is arranged in the middle of the upper forming mould and is located right above the tool containing concave part; the upper forming mould is further provided with a guide column; the lower forming mould is further provided with a guide sleeve which is in close fit with the guide column and the guide column can stretch into the guide sleeve to move up and down. According to the cold-extrusion sealed forming mould, the utilization of the mould can be increased; the cold-extrusion sealed forming mould not only can be applicable to machining circular products, but also can be applicable to machining products with special shapes.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of cold extrusion sealing shaping mould.
Background technology
Current cold-stamped mould does not seal, and also leaves the gap of several millimeters after upper and lower mould closure, and this mould is just applicable to circular product, if be special-shaped product for cold-extruded cylindrical, the cold extrusion mould not sealing is just inapplicable.Therefore, how to solve above-mentioned technical bottleneck, become technical barrier to be captured.
Summary of the invention
The object of the present invention is to provide a kind of mould that can improve to utilize the cold extrusion of power to seal shaping mould, this cold extrusion sealing shaping mould can either be applicable to the processing of circular product, can be applicable to again the processing of special-shaped product.
Technical scheme of the present invention is such:
A cold extrusion sealing shaping mould, it comprises shaping upper and moulding counterdie; The workpiece that offers mutual perforation at described moulding counterdie middle part put recess and thimble through hole and described workpiece put recess be positioned at thimble through hole above, on described thimble through hole, thimble moving up and down is installed; Described shaping upper middle part be provided with product film forming splenium and this product film forming splenium be positioned at described workpiece put recess directly over; On described shaping upper, be also provided with guide pillar, and on described moulding counterdie, be also provided with in can stretching into guide pin bushing with the friction tight guide pin bushing of above-mentioned guide pillar and described guide pillar and move up and down.
Compared with prior art, the present invention is after adopting said structure, and it has following beneficial effect:
Product film forming splenium and workpiece are put recess cooperating and are formed concavo-convex form, are convenient to safeguard, and by the structure that adopts guide pillar, guide pin bushing to cooperatively interact, can be conveniently aligning when facilitating shaping upper to enter moulding counterdie, when specific works, workpiece is placed on workpiece and puts recess the inside, shaping upper keeps motionless in the downward punching press of certain height and moulding counterdie, shaping upper is through guide pillar, the correcting of guide pin bushing, shaping upper drives its film forming compression leg slowly to enter into moulding counterdie the inside driving cold extrusion closed state until workpiece is pressed onto and default desired shape, therefore, the present invention not only can be applicable to the processing of circular product, also can be applicable to the processing of special-shaped product, thereby making some external forms is that special-shaped cold forging product can seal shaping mould with cold extrusion and develops and produce, greatly improved the power of utilizing of mould.
After reading by reference to the accompanying drawings the detailed description of embodiments of the present invention, it is clearer that the features and advantages of the invention will become.
Accompanying drawing explanation
The schematic diagram that Fig. 1 is embodiments of the present invention under duty not;
Fig. 2 is the structural representations of embodiments of the present invention under in working order.
The specific embodiment
With an embodiment, the present invention is further detailed explanation below, but should illustrate, protection scope of the present invention is not limited only to this.
Consult Fig. 1 and Fig. 2, a kind of cold extrusion sealing shaping mould, it comprises shaping upper 100 and moulding counterdie 200; The workpiece that offers mutual perforation at described moulding counterdie 200 middle parts put recess 20 and thimble through hole 21 and described workpiece put recess 20 be positioned at thimble through hole 21 above, thimble 22 moving up and down is installed on described thimble through hole 21; Described shaping upper 100 middle parts be provided with product film forming splenium 11 and this product film forming splenium 11 be positioned at described workpiece put recess 20 directly over; On described shaping upper 100, be also provided with guide pillar 10, and on described moulding counterdie 200, be also provided with in can stretching into guide pin bushing 23 with the friction tight guide pin bushing 23 of above-mentioned guide pillar 10 and described guide pillar 10 and move up and down.
When present embodiment is specifically used: workpiece 300 is placed on the workpiece of moulding counterdie 200 and puts recess 20 the insides, shaping upper 100 is in the downward punching press of certain height, wherein, in punching course, moulding counterdie 200 is motionless, shaping upper 100 is through guide pillar 10, the correcting of guide pin bushing 23, shaping upper 100 drives its film forming compression leg 11 slowly to enter into moulding counterdie 100 the inside driving cold extrusion closed states until workpiece is pressed onto and default desired shape, then, 100 liters times original height of shaping upper, the thimble 22 of moulding counterdie 200 ejects moulding counterdie 200 workpiece 300.
Although described by reference to the accompanying drawings embodiments of the present invention; but those skilled in the art can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
