Abstract
The utility model discloses a cold extrusion die. The cold extrusion die comprises an upper die base and a lower die base, the upper die base and the lower die base are arranged in a sliding guide mode through an upper die guide sleeve and a lower die guide post which are matched to each other, an upper female die is fixedly installed at the lower end of the upper die base, a female die outer frame is matched outside the upper female die, a lower base plate is fixedly mounted on the lower die base, an upper base plate is fixedly installed on the lower base plate, a lower clamping plate is fixedly mounted on the upper base plate, an upward cylinder is fixedly installed on each side of the upper base plate, an extrusion ring base plate is fixedly installed at the top of piston rods of the cylinders, an extrusion ring is fixedly mounted on the extrusion ring base plate, a die core penetrates the extrusion ring, the extrusion ring base plate and the lower clamping plate respectively in a sliding mode, and dowel bars which penetrate the upper base plate and the lower base plate are supported at the lower end of the die core. According to the cold extrusion die, repeated drawing process effects through stamping dies and stamping processes can be achieved, functions of a plurality of set of dies can be achieved through one set of dies, costs of materials are reduced, the production efficiency is improved, and the maximum benefit is achieved.
Description
Technical field
The utility model is mainly used in ultra-thin goods drawing and moulding field, it can be made solid member and the hollow object of different shape and produce the more complicated product of geometry, as the thin slice that is used for the cosmetic industry shell, the thin slice that is used for hand phone battery case etc., be specifically related to a kind of forming convax mould and die and directly push the cold extrusion die that forms product.
Background technology
General superthin section goods all adopt the mode of production of the many molds that repeatedly draw, and a lot of thin slice employing is drawn at all and can't be realized.All there are a lot of drawbacks from design, processing, die debugging in this mode of production to punching production, and Sheet Metal Forming Technology complexity, mold materials waste are seriously, the processing cumulative errors are big, the pincers worker debugging work load is heavy, have a strong impact on stamping production efficiency.In case so the application of cold extruding technique within the specific limits, will progressively replace casting, forging, pull and stretch and machining.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model is to propose diel and the Sheet Metal Forming Technology thereof that an a kind of procedure just can be realized repeatedly the drawing sequence effect, it can realize that a mold finishes the function of many molds, reduce material cost, enhance productivity, thereby realized the maximization of benefit.
The technical solution of the utility model is as follows:
A kind of cold extrusion die, comprise upper bolster, die shoe, upper die guide sleeve by being complementary between upper bolster and the die shoe, counterdie guide pillar slide-and-guide arranges, the lower end of upper bolster is installed with upper cavity die, the upper cavity die fit on has the die housing, be installed with lower bolster on the die shoe, be installed with upper padding plate on the lower bolster, be installed with lower plate on the upper padding plate, the both sides of upper padding plate are installed with cylinder up respectively, the top of the piston rod of cylinder is installed with extruding circle backing plate, is installed with the extruding circle on the extruding circle backing plate, has core rod to slide through the extruding circle respectively, extruding circle backing plate, lower plate, the lower end holder of core rod is equipped with passes upper padding plate, the transmission rod of lower bolster, die shoe has cavity, is provided with elastomer block in the cavity, and the lower end of described transmission rod is pressed on the elastomer block upper end.
Be integral by bolting between described lower plate, upper padding plate, the lower bolster.
Have stepped hole in the described upper padding plate, be combined with the head of bolt in the stepped hole, the upper end of bolt and core rod screw togather fixing.
The utility model cold extrusion process: at room temperature, whole upper mould part is descending, counterdie extruding circle withstands material in the effect of cylinder, upper cavity die is descending, push down material with the extruding circle, core rod moves upward under the effect of transmission rod and makes metal blank generation plastic deformation jointly and finish extruding with upper cavity die then, in the process of described extruding, all by calculating stroke work, extruding finishes the back mould and reaches pier death situation attitude for cylinder and transmission rod.
Be the technical scheme that realizes that its purpose is taked: the directly diel that forms of extruding of forming convax mould and die, it is characterized in that: 1, the moulding die cavity is darker, and 2, the shaped article wall thickness is quite thin.
The Sheet Metal Forming Technology of the diel of this novel punch-die moulding, whole cold extrusion process is simple, quick:
The beneficial effects of the utility model
The utility model has realized that a cover extrusion die is finished the function of many cover drawing dies even how cover draws the function that also can't realize, its beneficial effect also has:
1, reduces raw-material consumption; 2, enhance productivity; 3, can obtain the part of higher dimensional precision and less surface roughness value; But 4 manufacturing complex shapes parts; 5, improve the mechanical property of extrusion sections material; 6, enlarged material plastic working shaping scope etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of cold extrusion die, comprise upper bolster 1, die shoe 2, upper die guide sleeve 3 by being complementary between upper bolster 1 and the die shoe 2, the 17 slide-and-guide settings of counterdie guide pillar, the lower end of upper bolster 1 is installed with upper cavity die 4, upper cavity die 4 fit ons have die housing 5, be installed with lower bolster 6 on the die shoe 2, be installed with upper padding plate 7 on the lower bolster 6, be installed with lower plate 8 on the upper padding plate 7, the both sides of upper padding plate 7 are installed with cylinder 9 up respectively, the top of the piston rod of cylinder 9 is installed with extruding circle backing plate 10, be installed with extruding circle 11 on the extruding circle backing plate 10, there is core rod 12 to slide through extruding circle 11 respectively, extruding circle backing plate 10, lower plate 8, the lower end holder of core rod 12 is equipped with passes upper padding plate 7, the transmission rod 13 of lower bolster, die shoe 2 has cavity, be provided with elastomer block 14 in the cavity, the lower end of transmission rod 13 is pressed on the top board 18 of elastomer block 14 upper ends; Be fixed into one by bolt 15 between lower plate, upper padding plate, the lower bolster, have stepped hole in the upper padding plate, be combined with the head of bolt in the stepped hole, the upper end of bolt 16 and core rod screw togather fixing.
