Abstract

The utility model relates to an equal passage corner repeat extruding device, which comprises a vertical extrusion oil cylinder, a vertical extrusion convex die, an extrusion concave die, a corner extrusion passage and a bottom plate. The utility model is characterized in that an outlet of the extrusion concave die is provided with a passageway which lengthens at horizontal direction; the outlet end of the passageway which lengthens at horizontal direction is additionally provided with a horizontal extrusion oil cylinder and a horizontal extrusion convex die; the extrusion concave die has equal size structure at horizontal and vertical direction; the cross section of the lateral extrusion convex die is same with the cross section of the vertical extrusion convex die. The utility model has the advantages that because the extrusion efficiency is high, and extrusion pieces are extruded repeatedly in the extrusion concave die, the utility model omits the manual operation in a traditional device, and enhances the production efficiency; because the extrusion quality is high, and the extrusion pieces are in a three-way pressure stress state, the utility model enhances the material plasticity, reduces the microcrack generation, and enhances the quality.

Description

A kind of equal channel angular is pressurizing unit repeatedly
(1) technical field:
The utility model relates to a kind of equipment of metal material modification, and particularly a kind of equal channel angular of fining metal material grains is pressurizing unit repeatedly.
(2) background technology:
The equal channel angular extrusion technique is to make to be extruded solid metal material and detrusion to take place to reach the purpose of crystal grain thinning in the squeezing passage corner.Through obtaining having the solid metal material of ultra-fineization crystal grain after repeatedly pushing.Existing equal channel angular extrusion device as shown in Figure 1, in extrusion process, vertical extruding punch 1-2 extruding under the effect of vertical extrusion oil cylinder 1-1 is extruded material 1-4, makes it turn over 90 ° of corners along corner squeezing passage 1-5, on the corner is subjected to shearing force to make grain refinement.Be reentered into through the material after the extruding once again and carry out second time extruding among the Extruding die 1-3, after pushing through 3-5 time, the crystal grain of solid metal material has obtained very big refinement, and the performance of material is improved.Traditional pressurizing unit needs after every extruding once extrusion is taken out, and then packs into and carry out the extruding second time, and operation is complicated.The end of extrusion is a free end in addition, and the relatively poor material of plasticity is cracked in extruding.
(3) summary of the invention:
The purpose of this utility model is to design a kind of equal channel angular pressurizing unit repeatedly, and it is overcome the shortcoming in the said equipment, extrusion process is interrupted by single becomes continuously.
The technical solution of the utility model: a kind of equal channel angular is pressurizing unit repeatedly, comprise vertical extrusion oil cylinder, vertically push punch, Extruding die, corner squeezing passage and base plate, it is characterized in that in the Extruding die outlet horizontal direction extending channel being arranged, the port of export of extending channel has additional horizontal extrusion oil cylinder and level extruding punch in the horizontal direction; Said Extruding die becomes the structure that level equates with the vertical direction size; Said level extruding punch should be identical with its cross section of vertical extruding punch.
Above-mentioned said level extruding punch can be circular, square or Else Rule shape with its cross section of vertical extruding punch.
The course of work of the present utility model is: since equal channel angular repeatedly pressurizing unit both can vertically push, again can level extruding, therefore the material that is extruded in the Extruding die can be pushed repeatedly at the corner of corner squeezing passage.Saved the trouble of next time pushing again with after the extrusion taking-up.All the time be subjected to the effect of vertical and horizontal both direction extruding force owing to be extruded part in extrusion process in addition, so extrusion is in the three-dimensional compressive stress state, the plasticity that this can improve material crackle occurs in preventing to push.
Superiority of the present utility model is: (1) extruding efficient height, and extrusion is in all the time in the Extruding die and is pushed repeatedly, has saved the hand control in the conventional apparatus, has improved production efficiency; (2) extruding quality height, extrusion is in the three-dimensional compressive stress state, has improved the plasticity of material, has reduced the generation of micro-crack, has improved quality.
(4) description of drawings:
Accompanying drawing 1 is existing equal channel angular extrusion device structural representation.
Wherein: 1-1 be vertical extrusion oil cylinder, 1-2 for vertical extruding punch, 1-3 be Extruding die, 1-4 for be extruded material, 1-5 is that corner squeezing passage, 1-6 are base plate.
Accompanying drawing 2 is the related a kind of equal channel angular of the utility model overall structure schematic diagram of pressurizing unit repeatedly.
Wherein: 2-1 is vertical extrusion oil cylinder; 2-2 is vertical extruding punch; 2-3 is an Extruding die; 2-4 is for being extruded material; 2-5 is the corner squeezing passage; 2-6 is a base plate; 2-7 is horizontal extrusion oil cylinder; 2-8 is a level extruding punch.
(5) specific embodiment:
Embodiment: a kind of equal channel angular is the pressurizing unit (see figure 2) repeatedly, comprise vertical extrusion oil cylinder 2-1, vertically push punch 2-2, Extruding die 2-3, corner squeezing passage 2-5 and base plate 2-6, it is characterized in that in the outlet of Extruding die 2-3 horizontal direction extending channel (see figure 2) being arranged, the port of export of extending channel has additional horizontal extrusion oil cylinder 2-7 and level extruding punch 2-8 in the horizontal direction; Said Extruding die 2-3 becomes the structure (see figure 2) that level equates with the vertical direction size; Said level extruding punch 2-8 should be identical with its cross section of vertical extruding punch 2-2.
Above-mentioned said level extruding punch 2-8 can be for square with its cross section of vertical extruding punch 2-2.

Claims (2)

1, a kind of equal channel angular pressurizing unit repeatedly, comprise vertical extrusion oil cylinder, vertically push punch, Extruding die, corner squeezing passage and base plate, it is characterized in that in the Extruding die outlet horizontal direction extending channel being arranged, the port of export of extending channel has additional horizontal extrusion oil cylinder and level extruding punch in the horizontal direction; Said Extruding die becomes the structure that level equates with the vertical direction size; Said level extruding punch should be identical with its cross section of vertical extruding punch.
