Abstract
The present invention relates to a kind of automobile middle shaft Forging Technology, comprise the steps: initially with the flat anvil blocking base having arc convex surface；Circulation upset jumping-up, then shapes jumping-up, then two passage edgings, reaches two ends by the pressure down of mould and pulls out, and forging 90-degree rotation is extruded after completing by the first passage again, makes forging be squeezed into the shape of rule；Then finish-forging, trimming processes, after after 880～900 DEG C of oil hardening 0.5～1 hour, 600～620 DEG C are tempered 2～2.5 hours.It is uniform that the product that this technique produces has internal modification, and filling effect is good, and forging yield rate is high, the feature that production efficiency is high.
Description
Technical field
The invention belongs to technical field of forging, particularly relate to a kind of automobile middle shaft Forging Technology.
Background technology
Automobile middle shaft is the critical piece of variator, and its major function is to cooperate with each gear of main shaft, real
The transmission speed that existing automobile is different.The most mostly employing technique is: die forming jumping-up-two passage edging-finish-forging-trimming, by
Press down gap value and the impact on forging filling capacity of the blank specification in edging mould, have that filling is unreal and non-uniform phenomenon,
Have impact on the quality of forging, yield rate is relatively low, adds production cost.
Summary of the invention
The purpose of the present invention is in order to solve above-mentioned technical problem, it is provided that a kind of automobile middle shaft Forging Technology, including as follows
Step: initially with the flat anvil blocking base having arc convex surface；Circulation upset jumping-up, makes the internal fully deformation of blank uniformly, disappear
Except internal flaw, crystal grain thinning, improve blank mobility, then shape jumping-up, then two passage edgings, by the pressure down of mould
Reaching two ends pulling, forging 90-degree rotation is extruded after completing by the first passage again, makes forging be squeezed into the shape of rule；Connect
And the forging of two passages extruding carried out finish-forging, then the forging after finish-forging is carried out trimming process, after through 880～900 DEG C of oil
After quenching 0.5～1 hour, 600～620 DEG C are tempered 2～2.5 hours, and the flat anvil of described arc convex surface, by two or more in the middle part of it
The arc convex surface of equal radii is formed, smooth excessively by circular arc camber between adjacent circular arc convex surface.
Compared with prior art, the invention have the advantage that have internal modification uniformly, filling effect is good, forging yield rate
Height, the feature that production efficiency is high.
