Abstract
The invention discloses a kind of forging method of automobile bearing, manufacturing method includes the following steps：According to the required weight blanking of wind turbine variable-speed bearing Internal and external cycle, blank is made；First fire time heating：By the blank heating in heating furnace to 1260 ± 10 DEG C, heat preservation；Blank in stove is taken out, primary whole jumping-up is carried out to blank using forging anvil, forging stock is taken out and carries out pulling to it until process, carries out secondary whole jumping-up using forging anvil, be then punched out with punch and ring billet is made, and carry out shaping to ring billet；Punch in the step includes fixing piece, connector and the punch part of coaxial arrangement, new cooling device is added the invention avoids conventional production process, use the short-cut method, automobile bearing is set to be quickly cooled down in a short time, and it is unlikely to the too low generation cracking of temperature, net carbide, accurate size of the present invention are effectively finally controlled, produced automobile bearing meets the requirements.
Description
Technical field
The present invention relates to automotive parts manufacturing technology more particularly to a kind of forging methods of automobile bearing.
Background technology
The various pieces of vehicle are due to the difference required in design feature, and certain means suitable high intensity, some parts are then
It is required that high impact toughness, accordingly, there exist the accessories of local requirement varying strength；At present in vehicle of the manufacture with varying strength
When accessory, for requiring the part of high intensity, accessory is manufactured using heat treatment hardened steel plate, for requiring low intensive portion
Point, then it is manufactured using general steel plate, then the matching two or more different steel grades by way of welding or being cold-pressed
Part connects the parts of manufacture vehicle；In such a way that the material of varying strength is attached, due to the bullet between material
Property deformation difference lead to the inconsistent phenomenon of size occur, dimensional accuracy error is big.
Invention content
In consideration of it, the present invention provides a kind of forging method of automobile bearing, manufacturing method includes the following steps：
Step 1：According to the required weight blanking of wind turbine variable-speed bearing Internal and external cycle, blank is made；
Step 2：First fire time heating：By the blank heating in heating furnace to 1260 ± 10 DEG C, heat preservation；
Step 3：Blank in stove is taken out, primary whole jumping-up is carried out to blank using forging anvil, forging stock is taken out and it is pulled out
It is long then the forging stock after pulling to be carried out down from all directions and round as a ball until process, cylindrical blank is made；
Step 4：After taking out cylindrical blank, secondary whole jumping-up is carried out using forging anvil, is then punched out with punch and ring is made
Base, and shaping is carried out to ring billet；Punch in the step includes fixing piece, connector and the punch part of coaxial arrangement, the company
Fitting is frustum cone structure, and the fixing piece and punch part are then cylinder, and is located at up and down the two of the connector
End is provided with the card slot convenient for being connect with press machine in the side wall of the fixing piece；
Step 5：Second fire time heating：Ring billet after shaping is put into stove, and is heated to 1260 ± 10 DEG C, is kept the temperature；Step 6)
Expanding rolling ring：Taking-up ring billet, which is put on Ring Rolling Machine, carries out rolling ring；
Step 6：After forging material forging, positive opening tup spray equipment, and by spray equipment flow control in 0.8L/
min.At this point, tup is open-shaped motionless, advances by the mating operation machine rotation forging material of diameter forging machine and at the uniform velocity, spray equipment is sprayed
The cooling water mist gone out is equably sprayed in 30 seconds on forging material, to realize the process for being quickly cooled down forging material.
Using above-mentioned technical proposal, have the advantages that：
New cooling device is added the invention avoids conventional production process, using the short-cut method, makes automobile bearing in short-term
It is interior to be quickly cooled down, and it is unlikely to the too low generation cracking of temperature, finally effectively control net carbide, size essence of the present invention
Really, produced automobile bearing meets the requirements.
Specific implementation mode
