Exhaust holes are arranged in the cavity of the lower molds of finish forging and dummying, and resistance chutes are arranged on the edges of the lower molds of finish forging and dummying. All the molds are column shaped and adopt a H13 (4Cr5MoSiVi) material, the hardness scope of a heat process is HRC 42 to 46. The utility model utilizes a technic proposal of a precise steel piston forging mold to fill in the whole cavity of the mold with the heated slab, and guarantees the complete figuration of the forgeable piece. The performances of the mold include the good red hard property, high tenacity and good wear resistance as well as long service life, which is longer 2 to 3 times than the service life of the mold made of other materials. The size of the forgeable piece is precise after being processed; the quality of the appearance and the pass percentage is high.
Description
(1), technical field:
The utility model relates to a kind of steel precision forging die, and the precision forging that is mainly used in engine steel piston is shaped.
(2), background technology:
The key technology of steel piston is a fine forging technology, and the core of fine forging technology is exactly a precision forging die.This technology has following characteristics:
(1). the forging and molding difficulty of steel piston is big, and die life is short;
(2). steel piston size precision and surface quality require high, need to adopt precision die to forge; The shaping difficulty of steel piston is big, and the precision prescribed height at present, have only minority advanced industrial country such as Europe, the United States to grasp this technology, and it is short nearly all to be faced with die life, and forging surface quality is poor, and dimensional accuracy is difficult to difficult problems such as control.Key is that narrow during shaping, material overflows mold cavity easily and dark, does not guarantee that piston fully is shaped under the reaction of intracavity gas.
(3), summary of the invention:
The purpose of this utility model is to provide a kind of and can satisfies forging and fully be shaped, and satisfies that dimensional accuracy and surface quality require and the steel piston precision forging die in long life-span.
For achieving the above object, a kind of steel piston of the utility model precision forging die, comprise finish-forging patrix and finish-forging counterdie and blocking patrix and blocking counterdie, said finish-forging patrix and finish-forging counterdie and blocking patrix and blocking counterdie are the relatively independent moulds of two covers; Inside at the mold cavity of finish-forging counterdie, blocking counterdie is provided with steam vent, is provided with the resistance ditch in the edge of the upper end mold cavity of finish-forging counterdie and blocking counterdie.
The profile of described finish-forging patrix, finish-forging counterdie and blocking patrix, blocking counterdie all is designed to cylindrical shape, adopts H13 (4Cr5MoSiV1) material, heat treatment hardness scope HRC42-46.
In technique scheme since die cavity narrow forging is full of difficulty and dark, the difficult shaping in the mold cavity inside of finish-forging counterdie, blocking counterdie in the utility model is provided with steam vent, can discharge the interior gas of mold cavity; Edge at the upper end mold cavity of finish-forging counterdie and blocking counterdie is provided with the resistance ditch, and the resistance ditch can increase material from the resistance that the overlap bridge floor overflows, and the blank that helps heating is full of the entire die die cavity, thereby guarantees that forging fully is shaped.In addition, the utility model mould adopts H13 (4Cr5MoSiV1) material to make special thermal treatment, and H13 (4Cr5MoSiV1) material is usually used in die casting, the technology comparative maturity.But be used for big-and-middle-sized forging mold, rarely found both at home and abroad at present.Heat treatment die surface hardness is controlled at HRC42-46, and the outstanding feature of using the back to find is exactly that high-temperature behavior is good, and mainly show as: red hardness is good, the toughness height, and wearability is good.Synthesis is on die life now, than die life of other common used material mades exceeding 2-3 doubly.

(5), the specific embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
By Fig. 1, Fig. 2 as seen, a kind of steel precision forging die of the utility model comprises finish-forging patrix 1, finish-forging counterdie 2, blocking patrix 3, blocking counterdie 4, and finish-forging patrix 1, finish-forging counterdie 2 and blocking patrix 3, blocking counterdie 4 are the relatively independent moulds of two covers.Two mold patrixes 1 and 3 and the profile of counterdie 2 and 4 all be designed to cylindrical shape, not only convenient processing also makes things convenient for installation and the adjustment of mould on lathe.In the mold cavity 6 of finish-forging counterdie 2, blocking counterdie 4, set out steam vent 11, be provided with the position of resistance ditch 10 in the edge of mold cavity 6 upper ends of finish-forging counterdie 2, blocking counterdie 4, because die cavity is narrow and dark, forging is full of difficulty, the steam vent of leaving 11 can be discharged the gas in the mold cavity, resistance ditch 10 can increase material from the resistance that the overlap bridge floor overflows, and the blank that helps heating is full of the entire die die cavity, thereby guarantees that forging fully is shaped.
By Fig. 3, Fig. 4 as seen, a kind of steel precision forging die of the utility model is provided with steam vent 11 in the lower end of the inside of the mold cavity 6 of finish-forging counterdie 2 and blocking counterdie 4, edge, upper end, both sides at the mold cavity 6 of finish-forging counterdie 2 and blocking counterdie 4 respectively is provided with a resistance ditch 10, the steam vent of leaving 11 can be discharged the gas in the mold cavity, resistance ditch 10 can increase the resistance that material overflows from the overlap bridge floor, the blank that helps heating is full of the entire die die cavity, thereby guarantees that forging fully is shaped.
Fig. 5 is the mounting structure schematic diagram on lathe of a kind of steel piston of the utility model precision forging die; As seen from Figure 5, a kind of steel precision forging die of the utility model comprises finish-forging patrix 1, finish-forging counterdie 2, blocking patrix 3, blocking counterdie 4, and finish-forging patrix 1, finish-forging counterdie 2 and blocking patrix 3, blocking counterdie 4 are the relatively independent moulds of two covers.Two mold patrixes 1 and 3 and the profile of counterdie 2 and 4 all be designed to cylindrical shape, not only convenient processing also makes things convenient for installation and the adjustment of mould on lathe.Die shape all has the pressing plate groove, is separately fixed on upper bolster 5 and the die shoe 8 by pressing plate 7.Forging is put into the mold cavity 6 of mould, and the good forging that is shaped ejects mold cavity by push rod 9.Owing to be provided with push rod 9, the pattern draft of forging can design very for a short time, even can not make pattern draft, so not only can save material, and can reduce the machine-finish allowance of forging, thereby reduce the consumption of cutter.
Shown in Figure 6 is the monoblock type copper electrode 12 that processes according to the auxiliary design of CAD/CAM, the copper electrode 12 processing mold die cavity that is used for discharging.Copper electrode is compared with the conventional graphite electrode, has the surface smoothness height, and galvano-cautery consumes little, advantages such as dimensional stability is good, therefore the mold surface finish height that comes out of electric machining, dimensional uniformity is good, thereby has finally guaranteed the dimensional accuracy and the surface quality of forging requirement.
