Abstract
The utility model discloses a shift fork forming die which comprises a lower die and an upper die, wherein a fixed block is arranged in the center of the lower die; a sunk groove is formed in the center of the fixed block; the sunk groove is enlarged gradually from the bottom to the opening part; a bulge is arranged at the bottom of the sunk groove; the cross section of the bulge is I-shaped; a plurality of guide posts are arranged on the outer side of the fixed block; a punch pin is fixed to the lower end surface of the upper die; a groove matched with the bulge is formed on the lower end surface of the punch pin; and guide holes corresponding to the guide posts in position are formed on the upper die. The shift fork forming die has a simple structure; the sunk groove enlarged gradually from the bottom to the opening part is formed in the center of the lower die and the I-shaped bulge at the bottom of the sunk groove is matched with the groove on the punch pin of the upper die; meanwhile, the accuracy of positioning is good, so that material is discharged conveniently after being forged; and the processing efficiency is high, so that the manual labor intensity is reduced.
Description
Technical field:
The utility model relates to field of machining, relates in particular to a kind of shift fork mould.
Background technology:
Shift fork is a kind of name of part, and this part can be used for stirring other parts, in general is a kind of wishbone lever.Generally be used for the speed governing of gear.
The manufacturing process of shift fork generally is divided into steps such as blanking, heating, forging molding, side cut, fine finishining; After the blanking after middle frequency furnace heating; Workpiece after the heating is put into mould to be forged; Forging is under the effect of forging equipment and worker's (mould) tool, makes blank or ingot casting produce plastic deformation, with the processing method of the forging that obtains certain physical dimension, shape and quality.Original mould is because positioning accuracy is relatively poor, and the press forging after the forging and pressing is difficult to be taken away from mould, causes the process inefficiency, and manual work intensity is big.
The utility model content:
To the prior art problem, the purpose of the utility model provides a kind of shift fork mould, and is simple in structure, economic and practical, and working (machining) efficiency is high.
The technical scheme of the utility model is following:
The shift fork mould comprises counterdie, patrix, it is characterized in that: the counterdie center is provided with fixed block; The fixed block center has deep gouge, and the deep gouge bottom is provided with convexity, and protruding cross section is I-shaped; The described fixed block outside is provided with several leads; Described patrix lower surface is fixed with drift, and the drift lower surface has the groove that matches with described convexity, is provided with pilot hole with described lead correspondence position on the described patrix.
Described shift fork mould is characterized in that: described deep gouge is a rectangular pyramid shape, from the bottom to the oral area, increases gradually.
The utility model has the advantages that:
The utility model is simple in structure; Have the deep gouge of the taper that from the bottom land to the oral area, increases gradually in the centre of counterdie; Deep gouge bottom still has I-shaped convexity to match with groove on the patrix drift, and positioning accuracy is good simultaneously, make forge after easy-unloading; Working (machining) efficiency is high, reduces hand labor intensity.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
The shift fork mould comprises counterdie 1, patrix 2, and counterdie 2 centers are provided with fixed block 3; Fixed block 3 centers have deep gouge 4, and deep gouge 4 is a rectangular pyramid shape, from the bottom to the oral area, increases gradually; Deep gouge 4 bottoms are provided with convexity 5, and protruding 5 cross section is I-shaped, and fixed block 3 outsides are provided with several leads 6; Patrix 2 lower surfaces are fixed with drift 7; Drift 7 lower surfaces have the groove 8 that matches with protruding 5, are provided with pilot hole 9 with lead 6 correspondence positions on the patrix 2, are convenient in the groove 8 decline processes on the aligning punch 7 accurately and protruding 5 cooperate.
