Abstract
The utility model discloses a cold forging die which comprises a die body, a tungsten steel die core and an inner die, wherein the die body adopts a hollow sleeve that includes a stepped hole tapered from front to back, the inner die takes the shape of a stepped shaft that is tapered from front to back, the tungsten steel die core is embedded at the front part of the inner die, and the shape of the inner die is matched with that of the stepped hole of the die body. When the forming opening of a lower die is partially worn or damaged, the inner die is replaced instead of the whole die, thereby reducing the overall cost of the die.
Description
[technical field]
The utility model relates to forge die, relates in particular to a kind of cold forging die.
[background technology]
Traditional cold forging die generally comprises upper die and lower die, and as shown in Figure 1, stud with the core rod 2 of wolfram steel in the counterdie 1 and have molding port, because the impact that molding port frequently bears patrix, so molding port can produce wearing and tearing or damage prior to other positions of mould.Traditional counterdie is an integral type, in case local generation of the molding port of counterdie worn and torn or damage, just needs to change entire die, causes unnecessary waste.
[summary of the invention]
The technical problems to be solved in the utility model does not need to change whole bed die after providing local generation wearing and tearing of a kind of molding port or damage, can cost-effective cold forging pressing mold tool.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of cold forging die comprises die ontology, wolfram steel core rod and internal mold, and described die ontology is the sleeve of hollow, and described hollow sleeve comprises 1 pre-small post-large shoulder hole; The profile of described internal mold is pre-small post-large multidiameter, and described wolfram steel core rod is embedded in the front portion of internal mold, and the profile of internal mold and the shoulder hole of die ontology are suitable.
Above-described cold forging die, described internal mold comprise and connect mould and down connect mould that described wolfram steel core rod is embedded in and connects in the mould, and the profile that connects mould on described is that pre-small post-large multidiameter and the profile that time connects mould are cylindrical.
Above-described cold forging die, on connect mould length equal the length of wolfram steel core rod.
Above-described cold forging die comprises the second wolfram steel core rod, and the described second wolfram steel core rod is embedded in down and connects in the mould, and the second wolfram steel core rod is coaxial with the wolfram steel core rod.
The utility model cold forging die is divided into die ontology and internal mold two parts, and the wolfram steel core rod is embedded in the internal mold, when local generation wearing and tearing of the molding port of counterdie or damage, does not need to change entire die, as long as change internal mold, can reduce the totle drilling cost of mould.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the profile of prior art cold forging die.
Fig. 2 is the profile of the utility model cold forging die embodiment 1.
Fig. 3 is the profile of the utility model cold forging die embodiment 1 die ontology.
Fig. 4 is the profile of the utility model cold forging die embodiment 2.
[specific embodiment]
In the embodiment 1 of Fig. 2, the utility model cold forging die shown in Figure 3, comprise die ontology 3, wolfram steel core rod 2 and internal mold, internal mold by on connect mould 4 and under connect mould 5 and form.Die ontology 3 is the sleeve of hollow, and the front portion of hollow sleeve is an aperture 301, and the rear portion is a macropore 302, and both form shoulder hole.On connect mould 4 profile be pre-small post-large multidiameter, wolfram steel core rod 2 is embedded in and connects in the mould, on connect mould 4 length equal the length of wolfram steel core rod 3.On to connect the aperture 301 of the small end of mould 4 and hollow sleeve suitable, on to connect the macropore 302 of the big end of mould 4 and hollow sleeve suitable.The periphery that connects mould 5 down is cylindrical, and the macropore 302 of columniform periphery and hollow sleeve is suitable.
The embodiment 1 of the utility model cold forging die be divided into die ontology, on connect mould and under connect mould three parts, the wolfram steel core rod is embedded in and connects in the mould, when local generation wearing and tearing of the molding port of counterdie or damage, do not need to change entire die, to connect mould just passable as long as replace with, can save a large amount of mold materials, reduce the totle drilling cost of mould.
The structure of the utility model embodiment 2 as shown in Figure 4, embodiment 2 is that with the difference of embodiment 1 center that connects mould 5 down also is inlaid with wolfram steel core rod 6, wolfram steel core rod 6 with on the wolfram steel core rod 2 that connects in the mould coaxial.
Claims (4)
