Description

A kind of equal channel angular extrusion die with cylinder
Technical field
The utility model relates to a kind of mould structure, and refering in particular to a kind of control by cylinder can the equal channel angular extrusion die of self-emptying.
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, and corner extrusion passage will be processed in the die of traditional moulds, processing relative difficulty.
Utility model content
The utility model object provides a kind of control by cylinder can the equal channel angular extrusion die of self-emptying 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 cylinder, mainly comprises die shank, upper bolster, punch retainer, punch, die shoe, die pressing plate, die, die fixed cover, die base, lead and cylinder; Described die fixed cover and die base are all screwed and are connected on die shoe; Described die die fixed cover, die pressing plate and die base 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 cylinder is fixedly connected on die shoe; The piston nose of described cylinder is connected with push rod; Described die base and described die form L-type squeezing passage; The lateral cross section of described push rod is identical with the lateral cross section of squeezing passage; The central axis of the interconnection of described push rod and described L-type squeezing passage is located along the same line; The front end face of described push rod is connected, in arc-shaped with the corner of described L-type squeezing passage.
Preferably, described die base is step-like, and its step is positioned at the bearing of trend of the interconnection of described L-type squeezing passage.
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 cylinder of the utility model scheme, the difference maximum with traditional moulds is exactly add the opposite direction of the interconnection of L shape squeezing passage can be provided with push rod at die, and described push rod is connected on the piston of cylinder, can be controlled to seesaw along L shape squeezing passage interconnection direction by cylinder, the advantage arranging cylinder and push rod is after extruding terminates, only need to start cylinder by piston push rod to be moved right and just can take out extrusion and clout easily, easily can not only take out extrusion like this, there is no residual waste in mould when can ensure again to have extruded at every turn, decrease the infringement of extrusional slug to mould, extend the mold use life-span, save cost.

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 and 3, a kind of equal channel angular extrusion die with sliding bottom of the present utility model, mainly 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, die base 10, lead 9 and cylinder 13; Described die fixed cover 8 and die base 10 are all screwed and are connected on die shoe 5; Described die 7 die fixed cover 8, die pressing plate 6 and die base 10 is 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 cylinder 13 is fixedly connected on die shoe 5; The piston nose of described cylinder 13 is connected with push rod 11; Described die base 10 forms L-type squeezing passage with described die 7; The lateral cross section of described push rod 11 is identical with the lateral cross section of squeezing passage; Described push rod 11 is located along the same line with the central axis of the interconnection of described L-type squeezing passage; The front end face of described push rod 11 is connected, in arc-shaped with the corner of described L-type squeezing passage.
Further instruction, described die base 10 is step-like, and its step is positioned at the bearing of trend of the interconnection of described L-type squeezing passage.
The mold work process 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, the crystal grain of extrusion is made to obtain refinement, thus improve machinery and the physical property of the material of extrusion, after extruding terminates, start cylinder by piston push rod to be moved right and just can take out extrusion and clout easily, last being moved to the left by push rod by piston revert power is again returned to initial position, and the step of die holder can place collection basket, can be used for collecting the extrusion released by push rod and clout.
The equal channel angular extrusion die of the band cylinder of the utility model scheme, the difference maximum with traditional moulds is exactly add the opposite direction of the interconnection of L shape squeezing passage can be provided with push rod at die, and described push rod is connected on the piston of cylinder, can be controlled to move along L shape squeezing passage interconnection direction by cylinder, the advantage arranging cylinder and push rod is after extruding terminates, only need to start cylinder by piston push rod to be moved right and just can take out extrusion and clout easily, easily can not only take out extrusion like this, there is no residual waste in mould when can ensure again to have extruded at every turn, decrease the infringement of extrusional slug to mould, extend the mold use life-span, save cost.
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.
