Abstract
The invention discloses a flange forging process. The flange forging process includes the steps that blanking and heating are conducted successively, blank upsetting is conducted after heating, and the part formed after blank upsetting is a flange; an upper die core and an upper die of a split mode are utilized for conducting on the primary punching on a deep hole of the flange in a semi-open and semi-closed forging mode; after the flange is subjected to the trimming treatment, the secondary punching on a concave hole in the other end of the flange is conducted; shot blasting is performed after the shape is formed; portions needing fine machining are machined, and the flange is subjected to the rust-proof treatment and is packaged before leaving the factory. The flange is machined conveniently and released from the dies rapidly on the basis that materials are saved. Due to the split mode, the upper die core and the upper die are convenient to replace, the usage rate of the dies is increased, and cost is lowered. Forging on the appearance and an inner cavity can be finished rapidly.
Description
Technical field
The invention belongs to Machining Technology field, particularly relate to a kind of flange forging technique.
Background technology
Forging can make the blank part hardly differed with required part fast, easily, and with forging blank part fine finishining more out, can accelerate part production output, be a kind of convenient and practical mode of production.Flange is the casing flange at vehicle bridge two ends, is characterized in: middle hole is little dark again, and wheel rim muscle is thinner, is unfavorable for very much shaping, and middle deep hole mould is more unfavorable for the demoulding, and make it forge difficulty greatly, die life is low, and die cost is very high.Reduce the degree of depth in hole with traditional dies design and conventional forging, can reduce forging difficulty, but roughness is high, out-of-shape, adds machining allowance and difficulty, its machining processes is increased, long processing time, processing cost increases, and output is very low.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of flange forging technique, first described Forging Technology carries out blanking, heat again, Upsetting base can be carried out after heating, the part of Upsetting base aftershaping is flange body, utilize mold core and the mold of Split mold, the forging pattern of half-open semi-closure is adopted to carry out first time punching operation to the deep hole of flange body, and then after trimming process is carried out to flange body, carry out the second time punching operation of other end shrinkage pool, shape carries out ball blast after producing, machined is carried out to needing accurately machined position, antirust treatment and packing is carried out before dispatching from the factory.
Preferably, mold core and the mold of the employing during punching for the first time of described deep hole are Split type structure, and adopt along taper fit.
Preferably, the mold core end during punching for the first time of described deep hole is bulb shape.
Technique scheme tool has the following advantages: the present invention be allow flange body can save material basis on and can conveniently process, can fast demoulding, split type mold core and mold make die change convenient, mold use rate improves, reduce cost, the forging of profile and endoporus die cavity can be completed fast.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A kind of flange forging technique, first described Forging Technology carries out blanking, heat again, Upsetting base can be carried out after heating, the part of Upsetting base aftershaping is flange body, utilize mold core and the mold of Split mold, the forging pattern of half-open semi-closure is adopted to carry out first time punching operation to the deep hole of flange body, and then after trimming process is carried out to flange body, carry out the second time punching operation of other end shrinkage pool, shape carries out ball blast after producing, and to needing accurately machined position to carry out machined, before dispatching from the factory, carries out antirust treatment and packing.
Preferably, mold core and the mold of the employing during punching for the first time of described deep hole are Split type structure, and adopt along taper fit.
Preferably, the mold core end during punching for the first time of described deep hole is bulb shape.
Technique scheme tool has the following advantages: the present invention be allow flange body can save material basis on and can conveniently process, can fast demoulding, split type mold core and mold make die change convenient, mold use rate improves, reduce cost, the forging of profile and endoporus die cavity can be completed fast.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
