Description
Technical field
The utility model relates to drop stamping machinery manufacturing technology field, specifically a kind of hub axle tube through-hole forges tooling.
Background technique
Automobile hub axle tube is the security part of rear axle, is directly related to personal safety and vehicle safety, it is desirable that product is necessary
With good mechanical performance.With the continuous aggravation of market competition and rising steadily for raw material, market competition encounters huge
Hang-up.And existing production technology is first to make hub axle tube forging molding, then be machined bottom outlet, cost is excessively high, and because
For the not formed through-hole in hub axle tube inner cavity after forging, when using preheating quenching, inner cavity can not cool down in time, greatly reduce
The mechanical performance of product.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the invention of the present invention is to provide a kind of forgings of hub axle tube through-hole
Tooling forms through-hole after forging hub axle tube, to improve product mechanical performance.
For achieving the above object, the punching die of the utility model and die sleeve use taper fit, will with hydraulic press
Punching die is pressed into die sleeve, and punching die is made to combine closely with die sleeve；Small cushion block and piercing die in punching die bottom
Tool bottom is supported using big cushion block, and punching die, die sleeve, big cushion block are by backplanes support；Gland uses bolt by punching die
It is pressed abd fixed in base with die sleeve；Rough forging is imported into punching die, pierce punch moves from top to bottom, will forge
The bottom of blank is washed out, and waste material is discharged by big cushion block from bottom plate.
The small cushion block, big cushion block, bottom plate, base bottom have hole；Small cushion block bottom through-hole aperture and rough forging
The through-hole aperture of bottom is consistent；Big cushion block bottom through-hole aperture, bottom base plate through-hole aperture, base bottom through-hole aperture are all larger than
The through-hole aperture of rough forging bottom.
There are four the centers of bolt jackscrew adjustment punching die and die sleeve for the base circumferencial direction.
The punching die and die sleeve use 1 ° of cone match, after punching die fits closely in die sleeve, use oil pressure
Punching die is pressed into die sleeve 10mm again by machine.
The utility model compared with prior art, has the advantage that
1, it disposably washes out rough forging bottom to form through-hole using pierce punch, reduces machining processes.
2, because Forging Equipment Speed is fast, rough forging temperature still can achieve hardening heat after forging, straight for rough forging
Welding and quenching after rough forging forms through-hole, circulates convenient for quenching liquid in inner cavity, the perforation of hub axle tube rough forging inner cavity, waste heat
When quenching, hub axle tube inner cavity can be such that it cools down in time, carry out grade and reach 1-4 grades, substantially increase product mechanical performance.
3, pierce punch only has bottom work, can repeatedly be repaired, and the service life of mold is improved.
4, direct punch forming after the forging of rough forging through-hole, is not necessarily to machining, reduces cost of goods manufactured.
Detailed description of the invention
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of the utility model rough forging forming through hole process.
Specific embodiment
As shown in Figure 1 and Figure 2, the punching die 2 of the utility model and die sleeve 3 use 1 ° of cone match, and punching die 2 exists
After being fitted closely in die sleeve 3, punching die 2 is pressed into 10mm in die sleeve 3 again using hydraulic press, makes punching die 2 and mould
Set 3 is combined closely；Small cushion block 11 in 2 bottom of punching die is supported with 2 bottom of punching die using big cushion block 12, punching die
2, die sleeve 3, big cushion block 12 are supported by bottom plate 1；Punching die 2 and die sleeve 3 are pressed abd fixed on base 4 using bolt 6 by gland 5
It is interior；There are four the centers that bolt jackscrew 13 adjusts punching die 2 and die sleeve 3 for the base 4；Rough forging 7 is imported into
In punching die 2, make the automatic capturing in punching die 2 of rough forging 7, pierce punch 8 moves from top to bottom, by rough forging
7 bottom is washed out, and waste material 9 is discharged by big cushion block 12 from bottom plate 1, is exported waste material 9 using small skid, final hub axle tube
The molding of 10 blanks.
The small cushion block 11, big cushion block 12, bottom plate 1, base 4 bottom have hole；11 bottom through-hole aperture of small cushion block with
The through-hole aperture of 7 bottom of rough forging is consistent；12 bottom through-hole aperture of big cushion block, 1 bottom through-hole aperture of bottom plate, 4 bottom of base
Through-hole aperture is all larger than the through-hole aperture of 7 bottom of rough forging；4 bottom through-hole aperture of base >=1 bottom through-hole aperture of bottom plate, bottom
1 bottom through-hole aperture of plate >=12 bottom through-hole aperture of big cushion block.
Rough forging 7 after hot extrusion technique forges, first first cools down its bottom, avoids generating when the punching of bottom big
Measure burr；Because Forging Equipment Speed is fast, rough forging temperature still can achieve hardening heat after forging, directly quench for rough forging
Fire after rough forging forms through-hole, circulates convenient for quenching liquid in inner cavity, the perforation of hub axle tube rough forging inner cavity, immediate quenching
Hub axle tube inner cavity can be such that it cools down in time, substantially increase product mechanical performance.
The rough forging 7 of the utility model is imported into punching die 2, with 2 clearance fit of punching die, punching die 2
Inner hole positions the top of rough forging 7, while the presence in gap can look for pierce punch 8 and 7 inner hole of rough forging automatically
Just, punching precision is substantially increased.
