Description

A kind of processing technology of shift fork
Technical field
The present invention relates to vehicle arrangement manufacturing field, more particularly to a kind of processing technology of shift fork.
Background technology
With the development of automobile industry, safety and performance for vehicle propose higher requirement, and shift fork is on automobile Vital part, due to the particularity of its shape and its importance of performance, thus add the difficulty of its forging molding. In the prior art, domestic and international shift fork forging, low production efficiency, stock utilization are low, cause forging cost high.
Therefore, the utilization rate of material how is improved, and how to improve production efficiency, to reduce production cost, turns into this The art personnel important technological problems to be solved.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of processing technology of shift fork, this method improves material The utilization rate of material, production cost is reduced, improve production efficiency.
To achieve these goals, the present invention proposes a kind of processing technology of shift fork, comprises the following steps：
S10：Cast-iron alloy raw material is put into smelting furnace fusing；
S20：Cast-iron alloy raw material after fusing is subjected to ingot casting, forms ingot blank；
S30：Above-mentioned ingot blank is heated to 1000 DEG C ~ 1200 DEG C, and forging mold is heated to 800 DEG C ~ 950 DEG C, during heating Between be more than 1 hour；
S40：The cylindrical ingot blank is put into the forging mold, with punch ingot blank, blank is full of whole mould Shift fork blank is formed, the starting forging temperature of forging is 1000 DEG C ~ 1200 DEG C, and final forging temperature is more than or equal to 900 DEG C；
S50：The shift fork blank is subjected to precompressed and final pressure forms shift fork；
S60：Forging post processing：It is heated to 1000 DEG C and is incubated 2 hours, is put into oil and is cooled to 40 DEG C ~ 60 DEG C fuel-displaced air coolings, then quickly Carry out 100 DEG C of lonneal processing.
In addition, according to a kind of processing technology of shift fork of the present invention, there can also be following technical characteristic：
Preferably, in the step S40, the starting forging temperature of forging is 1100 DEG C, and final forging temperature is 1000 DEG C.
Preferably, in step S60, it is put into oil and is cooled to 50 DEG C.
By adopting the above-described technical solution, the invention has the advantages that：This method improves the utilization rate of material, reduces Production cost, improve production efficiency.
Embodiment
A kind of processing technology of shift fork according to embodiments of the present invention, comprises the following steps：S10：By cast-iron alloy raw material It is put into smelting furnace fusing；S20：Cast-iron alloy raw material after fusing is subjected to ingot casting, forms ingot blank；S30：Above-mentioned ingot blank is heated 800 DEG C ~ 950 DEG C are heated to 1000 DEG C ~ 1200 DEG C, and by forging mold, the heat time is more than 1 hour；S40：By described in Cylindrical ingot blank is put into the forging mold, with punch ingot blank, blank is formed shift fork blank, forging full of whole mould The starting forging temperature made is 1000 DEG C ~ 1200 DEG C, and final forging temperature is more than or equal to 900 DEG C；Preferably, the starting forging temperature of forging is 1100 DEG C, final forging temperature is 1000 DEG C；S50：The shift fork blank is subjected to precompressed and final pressure forms shift fork, it is preferable that is put into 50 DEG C are cooled in oil；S60：Forging post processing：Be heated to 1000 DEG C be incubated 2 hours, be put into oil be cooled to 40 DEG C ~ 60 DEG C it is fuel-displaced Air cooling, then 100 DEG C of lonneals processing of quick progress.This method improves the utilization rate of material, reduces production cost, improves production Efficiency.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is example Property, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentioned Embodiment is changed, changed, replacing and modification.
