On described die shoe 1, be provided with one and hold the cavity 12 that falls mould 11 under described, described cavity 12 runs through the front- back 13,14 of described die shoe, under described, fall mould 11 and be arranged in this cavity 12, fall under described and on mould 11, be provided with one and run through the semicircular arc groove 15 that falls the front-back of mould 11 under described.
In described top mold frame 2, be provided with one and hold the cavity 22 that falls mould 21 on described, cavity 22 in described top mold frame 2 runs through the front-back 23,24 of described top mold frame 2, on described, fall mould 21 and be arranged in this cavity 22, fall on described and on mould 21, be provided with one and run through the semicircular arc groove 25 that falls the front-back of mould 21 on described.
Under described, fall mould 11 with described on fall mould 21 and be oppositely arranged, under it, fall semicircular arc groove 15 on mould 11 with described on fall semicircular arc groove 25 on mould 21 coordinate to clamp object.
Cavity 12 both sides of described die shoe 1 are respectively provided with a guide pillar blind hole 31, and cavity 22 both sides of corresponding described top mold frame 2 are respectively provided with a guide pillar through hole 32; Described guide pillar 3 is two, and insert in a guide pillar blind hole 31 one end of a guide pillar 3, and the other end inserts in the guide pillar through hole 32 of a corresponding side.
On described each guide pillar 3, be provided with elastic device.
Described elastic device can be spring 33 in a preferred embodiment.
As shown in Figure 2, the middle part of described die shoe 1 cavity 12 both sides is respectively provided with a lug boss 16, and 22 liang of middle side parts of cavity of corresponding described top mold frame 2 are respectively provided with a depressed part 26.
The front-back that falls mould 21 on described is also connected with described top mold frame 1 by pressing plate 4 respectively.
Reenter shown in Fig. 2, in top mold frame 2 corresponding to described pressing plate 4 one end, be provided with connecting hole 41, in this connecting hole 41, be provided with backing pin 42, by making screw 43 and coordinating of described backing pin 42 described pressing plate 4 one end be fixedly connected with described top mold frame 2;

The screw 43 at described pressing plate 4 two ends can be soket head cap screw.
Fig. 4 is according to the structural representation that falls mould on an embodiment of the utility model.As shown in Figure 4, the arc radius R1, the R2 that above fall the end to end of the semicircular arc groove 25 on mould 21 gradually change, and the radius R 1 of one end can be that 240 millimeters, the radius of other end R2 can be 225 millimeters.
Fig. 5 is according to the structural representation that falls mould under an embodiment of the utility model.As shown in Figure 5,, the arc radius R3, the R4 that fall the end to end of the semicircular arc groove 15 on mould 1 under described also gradually change, and the radius R 3 of one end can be that 240 millimeters, the radius of other end R4 can be 225 millimeters.
The hydraulic press of above embodiment falls mould, can be with free-forging hydraulic forging pole time, supports the use, and the blank after rough forge is stretched into pass and draw and be swaged into circular bar.
Be designed to two cover passes and intersect total part, solve the two cover passes uneven problem of loading, reduce and change the pass time, raise labour productivity.
Falling nib type is preformed and final shaping unit two-piece design, and distortion rationally, forging rod is straight, and any surface finish, size are easy to control, and tolerance surplus is little.
Base is changed a little and can be supported the use with each type hydraulic machine anvil storehouse, is particularly suitable for fast forging press supportingly, and Technological adaptability is strong.
The utility model simple structure, be convenient to make, reliability is high.
