Description

A kind of assembling die for being used to make hubbed flange
Technical field
The utility model is related to flange forging equipment, specifically a kind of assembling die for being used to make hubbed flange.
Background technology
Hubbed flange is produced with die forging in process of production, and mold used is all whole, during use, mould Tool damaged condition is especially big, and especially the top half damage of mold is fast, and lower half portion is intact, so mold cannot It uses, the mold more to renew, the expense of such mold is especially high, increases the production cost of enterprise, reduces the effect of enterprise Benefit.
Invention content
To solve above-mentioned technical problem, a kind of assembling die for being used to make hubbed flange is provided, extends mold Service life, reduce production cost, increase economic efficiency, product quality stablize, operational sequence is simple, good forming effect.
The utility model solve its technical problem the technical solution adopted is that：
A kind of assembling die for being used to make hubbed flange, includes upper die head and lower mold body, the upper die head is provided with For the molding cylindrical cavity of hubbed flange ring flange, the lower mold body is provided with molding for the high neck portion of hubbed flange Round platform cavity is put, the bottom of the upper die head combines the molding cavity to form whole hubbed flange with the top of lower mold body, institute It states upper die head to be fixedly connected with lower mold body, during work, embryo material is positioned in the cylindrical cavity of upper die head, is placed on the upper die head Locating cover, forging and stamping punch, which is placed in locating cover centre bore, carries out forging stretching one-pass molding, forms complete hubbed flange forging Part blank.
The combination junction periphery of the upper die head and lower mold body sets weld bond, and upper die head is fixed under by welding manner Die body is integrally formed.
The assembling die uses 5CrNiMo, RC45 ° of heat treatment hardness, the anti-blow energy 45T of mold.
Original unitary mould is designed as the parts of upper die head and the combination of lower mold body two by the utility model, upper and lower two Divide damage that can be individually replaced, extend 3-5 times of the service life of mold, improve the utilization rate of mold, reduce production mould Cost, improve the economic benefit of enterprise, the product quality of making is stablized, and molding effect is good, simple in structure, operation side Just, it is easy to utilize.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the shaping schematic view of the utility model mold.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments：
As shown in Figs. 1-2, the assembling die for being used to make hubbed flange includes upper die head 1 and lower mold body 2, described Upper die head 1 is provided with for the molding cylindrical cavity of hubbed flange ring flange, and the lower mold body 2 is provided with for hubbed flange height The molding inverted round table cavity of neck portion, the bottom of the upper die head 1 combine to form whole high cervical approach with the top of lower mold body 2 Blue molding cavity, the upper die head 1 are fixedly connected with lower mold body 2, and during work, embryo material is positioned over the cylindrical cavity of upper die head 1 It is interior, placement positioning lid 3 on the upper die head 1, forging and stamping punch 5 be placed in 3 centre bore of locating cover carry out forging stretch once into Type forms complete hubbed flange forging blank.
The combination junction periphery of the upper die head 1 and lower mold body 2 sets weld bond 4, and upper die head 1 is fixed by welding manner It is integrally formed with lower mold body 2.
The assembling die uses 5CrNiMo, RC45 ° of heat treatment hardness, the anti-blow energy 45T of mold.
The specific forging technology process of the utility model is as follows：
1）Assembling die is preheated 250 degree -- 300 degree use again；
2）Embryo material forging is arrived places embryo material in the cavity again less than cylindrical cavity size；
3）Locating cover 3 is placed on 1 top surface of upper die head to buckle well；
4）Punch 5 used is placed on progress forging stretching in 3 centre bore of locating cover；
5）Neck is stretched with punch 5 and punching one-step moulding, punch tip are consistent with 1 die orifice transverse plane of upper die head；
6）After forging drawing and forming, then with punch from 2 bottom of lower mold body the one piece of incision ejection of the clout of connection and punch；
7）A complete hubbed flange forging blank is formed after forging ejection.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model also should Belong to the scope of protection of the utility model.
