Abstract
The utility model relates to 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.The structural advantages of equal channel angular extrusion die of the present utility model 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.
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 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.
Utility model content
The utility model object is the equal channel angular extrusion die providing a kind of effective minimizing punch wearing and tearing in order 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, 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 utility model compared with prior art has following advantages:
The equal channel angular extrusion die of the utility model scheme, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of equal channel angular extrusion die 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, punch base; 11, convex die rod; 12, guide pin bushing; 13, guide pillar.
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 Figure 1, a kind of equal channel angular extrusion die 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 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 described in the utility model, 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 described in the utility model, 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.
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.
