Abstract
The present invention discloses an equal channel angular extrusion mold with a sliding base. The equal channel angular extrusion mold mainly comprises a mold handle, an upper mold seat, a convex mold fixation plate, a convex mold, a lower mold seat, a concave mold pressing plate, a concave mold, a concave mold fixation sleeve and guiding columns, wherein the lower end surface of the concave mold is connected with a sliding base, a track fixation plate with a sliding block track is arranged between the sliding base and the lower mold seat, the track fixation plate and the lower mold seat are fixedly connected through screws, the sliding base and the track fixation plate can relatively slide along the track direction, the concave mold and the sliding base form an L-shaped extrusion channel, and the direction of the transverse channel of the L-shaped extrusion channel is the same as the direction of the track. The equal channel angular extrusion mold of the present invention has the following advantages that: the base can slide along the fixed track, the base moves to the right along with the material head of the extruded member during the extruding, and the remaining material can be easily taken out only requiring moving of the base to the right after completing the extruding, such that the damage of the extruded waste on the mold is reduced, and the service life of the mold is prolonged.
Description
Technical field
The present invention relates to a kind of mould structure, refer in particular to a kind of equal channel angular extrusion die facilitating the band sliding bottom of feeding and clear away waste.
Background technology
Equal-channel Angular Pressing technology is a kind of new technology preparing bulk nanostructured material grown up nearly decades, mainly through the intimate pure shear effect in deformation process, make the crystal grain of material obtain the high homogeneity of refinement and interior tissue, thus the machinery of material and physical property are significantly improved.The waste material of traditional moulds cannot directly take out, the extruding of lower passage can only be relied on to be extruded by waste material, although the function of back pressure effectively can be served as like this, make secondary crimp more perfect, but the extruding of every procedure all can have residual clout in a mold, by the time must descend during the extruding of passage and could be extruded, therefore die processing relative difficulty.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of equal channel angular extrusion die facilitating the band sliding bottom of feeding and clear away waste.
Technical solution of the present invention is achieved in that a kind of equal channel angular extrusion die with sliding bottom, comprises die shank, upper bolster, punch retainer, punch, die shoe, die pressing plate, die, die fixed cover and lead; Described die die fixed cover and die pressing plate are fixed; Described die shoe is connected by lead with upper bolster; Described upper bolster is screwed and is connected on die shank; Described punch retainer is screwed and is connected on upper bolster; Described punch is screwed and is arranged on punch retainer; Described die lower surface is connected with sliding bottom; The track fixed head of band slider track is provided with between described sliding bottom and die shoe; Described track fixed head and die shoe are by screw fixed-link; Can direction along ng a path relative sliding between described sliding bottom and track fixed head; Described die and sliding bottom form L-type squeezing passage; The interconnection of described L-type squeezing passage is identical with orbital direction.
Preferably, described sliding bottom and track fixed head adopt splayfooted riveting method to be connected.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The equal channel angular extrusion die of band sliding bottom of the present invention, slidably base is added at die exactly with the difference that traditional moulds is maximum, the advantage arranging sliding bottom is that base can slide along fixing track, when extruding is carried out, base moves right along with the stub bar of extrusion, at the end of extruding, only need continuation to be moved right by base and just can take out clout easily, residual waste is not had in mould when such energy ensures to have extruded at every turn, decrease the infringement of extrusional slug to mould, extend the mold use life-span, save cost.

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the equal channel angular extrusion die of band sliding bottom of the present invention;
Accompanying drawing 2 is the structural representation of another angle of the equal channel angular extrusion die of band sliding bottom of the present invention;
Wherein: 1, die shank; 2, upper bolster; 3, punch retainer; 4, punch; 5, die shoe; 6, die pressing plate; 7, die; 8, die fixed cover; 9, lead; 10, sliding bottom; 11, track fixed head; 12, extrusion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As shown in accompanying drawing 1,2, a kind of equal channel angular extrusion die with sliding bottom of the present invention, comprises die shank 1, upper bolster 2, punch retainer 3, punch 4, die shoe 5, die pressing plate 6, die 7, die fixed cover 8 and lead 9; Described die 7 die fixed cover 8 and die pressing plate 6 are fixed; Described die shoe 5 is connected by lead 9 with upper bolster 2; Described upper bolster 2 is screwed and is connected on die shank 1; Described punch retainer 3 is screwed and is connected on upper bolster 2; Described punch 4 is screwed and is arranged on punch retainer 3; Described die 7 lower surface is connected with sliding bottom 10; The track fixed head 11 of band slider track is provided with between described sliding bottom 10 and die shoe 5; Described track fixed head 11 and die shoe 5 are by screw fixed-link; Can direction along ng a path relative sliding between described sliding bottom 10 and track fixed head 11; Described die 7 forms L-type squeezing passage with sliding bottom 10; The interconnection of described L-type squeezing passage is identical with orbital direction.
Further instruction, described sliding bottom 10 and track fixed head 11 adopt splayfooted riveting method to be connected.
The equal channel angular extrusion die operation principle of band sliding bottom of the present invention is as follows: be first positioned over by extrusion in the vertical passage of L-type squeezing passage, install each parts, die shank can be driven by hydraulic-driven or motor, after driving, punch moves in the vertical passage of die, punch promotes the vertical passage of extrusion through L shape squeezing passage, and extrude from the interconnection of L shape squeezing passage, by this deformation process, make the crystal grain of extrusion obtain refinement, thus improve machinery and the physical property of the material of extrusion.The equal channel angular extrusion die of the band sliding bottom of the present invention program, slidably base is added at die exactly with the difference that traditional moulds is maximum, the advantage arranging sliding bottom is that base can slide along fixing track, when extruding is carried out, base along with extruding pieces stub bar move right, at the end of extruding, only need continuation to be moved right by base and just can take out clout easily, residual waste is not had in mould when such energy ensures to have extruded at every turn, decrease the infringement of extrusional slug to mould, extend the mold use life-span, save cost.
The equal channel angular extrusion die of band sliding bottom of the present invention, its structure is simple, processing and manufacturing is simple, cost-saving, the die of tradition equal channel angular extrusion die needs to offer L-type squeezing passage, and L shape squeezing passage of the present invention is formed by die and sliding bottom, significantly reduce the manufacture method of die, effectively save the manufacturing cost of mould.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
