Description
Technical field
The present invention relates to the improvement of cross wedge rolling production technology, specifically a kind of shaft forgings blank cross wedge rolling production technology
And hydraulic pressure alignment crop forming machine.
Background technology
Present shaft forgings blank cross wedge rolling production technology is completed by following steps：A, blanking：According to the axle class produced
Part type intercepts the bar of fixed length with numerical control band sawing machine；B, heating in medium frequency：Bar is heated with medium-frequency induction furnace；C, roll
System：The bar of heating is rolled using cross wedge rolling machine, forms hot blank, the axis of this hot blank is bending；D, heat
Alignment：Hot blank is straightened using three-roll unbender, it is a straight line its axis is tried one's best, but not reaches and go completely into one
The degree of straight line；E, ultrasonic examination：The blank of cooling is detected a flaw using supersonic detector, rejects unqualified blank；
F, bistrique：The both ends of qualified blank are polished with abrasive machine, remove the protrusion of end, are advantageous to the processing of end center hole；
G, isothermal normalizing：Blank is put into isothermal normalizing furnace, after the completion of be cooled to room temperature；H, impeller blasting：Using shot-blast cleaning machine
Remove the oxide skin that blank surface is formed；I, finished product blank is made in hydraulic pressure alignment：First blank load is put in dial gauge two to rotating
On wheel, the rotation situation of blank observation blank is rotated, the maximum projecting point of bending is found out and marks, be then placed within hydraulic pressure alignment
On machine, there are two symmetrical dops on the workbench of hydraulic straightening machine, the both ends of blank are individually positioned on the dop at both ends, and
The maximum projecting point for making bending upward, starts the maximum projecting point that hydraulic punching head pushes bending, by the empirically determined of operating personnel
The distance pushed, after the completion of, then blank is placed on rotating wheel and detected again, it is such as unqualified, then need to repeat.Make at present
This hydraulic straightening machine, by frame, oil storage tank, motor, oil pump, oil circuit integrator, oil cylinder, control cabinet and workbench, V-type
Dop is formed, and oil storage tank, motor, oil pump and oil circuit integrator, motor are fixed with the top of frame and is connected with oil pump, oil pump

Two V-type dops are fixed with, the expansion link of oil cylinder faces the middle part of two V-type dops.
It is disadvantageous in that：Such as utilize the automobile gearbox gear axis blank of cross wedge rolling production, during rolling, blank
Bending is easily caused, product enters back into three-roll unbender and carry out finishing heat alignment, this process needs after the completion of cross wedge rolling machine rolling
There are two people to complete；After gear shaft blank rolling, both ends have one section of material head, it is necessary to which both ends are installed and cut on cross wedge rolling die
Knife, to treat earnestly to fall material head after the completion of product rolling, after fervent material head, centre bit is equipped with a heels, and diameter has 5-6mm,
For height 3-4mm, it is necessary to be ground off piece by piece with emery wheel, grinding speed is slower, per tour 600；Blank is after isothermal normalizing, due to passing through
High-temperature heating, yielding bending need to carry out cold alignment, and this straightening technology is that product is placed on into press bench V-type dop
Above, with hydraulic press, step is straightened one by one, then with centimeter check, this aligning method is less efficient, and per tour is straightened 420.
