Abstract
The utility model relates to a kind of equal channel angular extrusion die with sliding bottom, mainly comprises die shank, upper bolster, punch retainer, punch, die shoe, die pressing plate, die, die fixed cover and lead; 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.The advantage of equal channel angular extrusion die of the present utility model 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, decrease the infringement of extrusional slug to mould, extend the mold use life-span.
Description
Technical field
The utility model relates to a kind of mould structure, refers 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.
Utility model content
The utility model object provides a kind of equal channel angular extrusion die facilitating the band sliding bottom of feeding and clear away waste to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: 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 utility model compared with prior art has following advantages:
The equal channel angular extrusion die of the band sliding bottom of the utility model scheme, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the equal channel angular extrusion die of band sliding bottom of the present utility model;
Accompanying drawing 2 is the structural representation of another angle of the equal channel angular extrusion die of band sliding bottom of the present utility model;
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 drawings and the specific embodiments, the utility model is described in further detail.
As shown in accompanying drawing 1,2, a kind of equal channel angular extrusion die with sliding bottom of the present utility model, 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 the band sliding bottom of the utility model scheme 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 utility model scheme, 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 described in the utility model, 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 utility model is formed by die and sliding bottom, significantly reduce the manufacture method of die, effectively save the manufacturing cost of mould.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
