Abstract
The invention discloses an equal-channel angular extrusion die. The equal-channel angular extrusion die comprises a die handle, an upper die seat, a male die fixing plate, a male die, a lower die seat, a female die pressing plate, a female die, a female die fixing sleeve and a guiding column; the female die fixing sleeve is fixedly connected to the lower die seat through a screw; the female die is fixed through the female die fixing sleeve and the female die pressing plate; the lower die seat is connected with the upper die seat through the guiding column; the upper die seat is fixedly connected to the die handle through a screw; the male die fixing plate is fixedly connected to the upper die seat through a screw; the male die comprises a male die pedestal and a male die rod; the male die pedestal is fixedly arranged on the male die fixing plate through a screw; and the male die pedestal is connected with the male die rod through a riveted joint. The equal-channel angular extrusion die has the following structural advantages: unnecessary wearing caused by complete contact of the male die and the female die is avoided, and the worn male die rod can be replaced to prolong the integral service life of the die and make the stress highly concentrated on the male die.
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 of effective minimizing punch wearing and tearing.
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 upper end of the punch of traditional moulds is fixedly installed in punch retainer, and lower end is inserted in the squeezing passage of die, during work, die shank controls punch and vertically moves, punch and the large-area contact wear of die are relatively more serious, and extrusion stress is also concentrated not, and operating efficiency is poor.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the equal channel angular extrusion die proposing a kind of effective minimizing punch wearing and tearing.
Technical solution of the present invention is achieved in that a kind of equal channel angular extrusion die, mainly comprises die shank, upper bolster, punch retainer, punch, die shoe, die pressing plate, die, die fixed cover and lead; Described die fixed cover is screwed and is connected on die shoe; 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 comprises punch base and convex die rod; Described punch base is screwed and is arranged on punch retainer; Described punch base is connected by riveted joint with convex die rod.
Preferably, described lead comprises the guide pin bushing and guide pillar that match.
Preferably, described lead has four, is arranged on the corner of die shoe and upper bolster.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Equal channel angular extrusion die of the present invention, punch base and convex die rod is comprised at punch exactly with the difference that traditional moulds is maximum, in stairstepping, pressure ram when described convex die rod is work, the advantage of such design avoids punch contact completely with die and shine into wearing and tearing unnecessary, and the convex die rod of replaceable wearing and tearing, the overall service life of mould is increased, and stress is highly concentrated in convex die rod.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of equal channel angular extrusion die 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, punch base; 11, convex die rod; 12, guide pin bushing; 13, guide pillar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As shown in Figure 1, a kind of equal channel angular extrusion die, 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 and lead 9; Described die 7 fixed cover is screwed and is connected on die shoe 5; Described die 7 die fixed cover 8 and die pressing plate 6 are fixed; Described die shoe 5 is connected by lead 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 comprises punch base 10 and convex die rod 11; Described punch base 10 is screwed and is arranged on punch retainer 3; Described punch base 10 is connected by riveted joint with convex die rod 11
Further instruction, described lead 9 comprises the guide pin bushing 12 and guide pillar 13 that match.
Further description, described lead 9 has four, is arranged on the corner of die shoe 5 and upper bolster 2.
Equal channel angular extrusion die of the present invention, its die shank is driven by hydraulic-driven or motor, it drives punch to move in the vertical passage of the L-type passage of die, to be extruded is placed with in the vertical passage of die, convex die rod promotes extrusion through L-type passage, by deformation process, make the crystal grain of extrusion obtain refinement, thus improve machinery and the physical property of material.
Equal channel angular extrusion die of the present invention, processing and manufacturing is simple, punch design is become stairstepping, the advantage of such design avoids punch contact completely with die and shine into wearing and tearing unnecessary, and the convex die rod of replaceable wearing and tearing, the overall service life of mould is increased, and makes stress be highly concentrated in convex die rod, operating efficiency is good.
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.
