The advantages such as good, noise is little；Regularity of Workpiece of Cross Wedge Rolling workpiece has metallic fiber streamline and obtains carefully along product design continuous distribution, crystal grain
The feature such as change, product size is stable.
3rd step: also as in figure 2 it is shown, the pull bar that slide rail 206 sliding is come rolls blank, insert electricity by manually or mechanically hands
In the bending mould of dynamic fly press 207, under the effect of bending mould, the aluminium alloys for automobile pull bar of the present invention is rolled
Blank bends to the shape corresponding with final pull bar.
Fig. 6 shows the bending mould of the aluminium alloys for automobile pull bar of the present invention.As it can be seen, fly press cope match-plate pattern
601 are installed on slide block lower surface, and fly press lower bolster 602 is installed on work top.The bending fixing peace of upper mold 603
Being loaded on the lower surface of fly press cope match-plate pattern 601, bending lower mold 604 is installed on fly press lower bolster 602 upper end
On face.When bending upper mold 603 and bending lower mold 604 close, pull bar can be rolled blank and bend to and final pull bar phase
Corresponding shape.Bending upper mold 603 and bending lower mold 604 are installed on the left side of electric screw press 207 work top.
Pull bar rolling blank after bending is positioned on conveyer belt 210 as shown in Figure 2 by manually or mechanically hands, passes through
This pull bar bending blank is sent to the right next procedure by conveyer belt 210.
In the BENDING PROCESS of aluminium alloys for automobile pull bar of the present invention rolling blank, mould is heated to: 300-400 DEG C,
To prevent pull bar rolling blank temperature in BENDING PROCESS to be reduced under final forging temperature, thus affect pull bar quality.
The most as shown in Figure 6, the right side of electric screw press 207 work top is additionally provided with edger, has more detailed below
Thin explanation.
4th step: upon bending, temperature is less than final forging temperature to the aluminium alloys for automobile pull bar rolling blank of the present invention, because of
This, need again to heat.
Fig. 2 shows the box type heater 209 of aluminium alloys for automobile pull bar manufacturing process of the present invention.As it can be seen, transmit
Band 210 is through this box type heater 209, and the product that conveyer belt 210 transmits can be heated and insulation during transmitting, and quilt
It is sent to next procedure.
The pull bar bending blank of the present invention is heated to 470-490 DEG C in this box type heater 209, and is incubated 2 minutes.
Experiment shows, described aluminum alloy pull rod bending blank is heated to this temperature range and is incubated, can effectively prevent at deformation after unloading
During, produce the microdefects such as such as coarse-grain inside aluminum alloy pull rod.
5th step: the aluminium alloys for automobile pull bar bending blank after heating is sent to such as Fig. 2 institute by conveyer belt 210 again
At the hydraulic press 211 shown, by the method for manually or mechanically hands, this pull bar bending blank is positioned over the mould of hydraulic press 211
On, carry out blocking and finish-forging.
Fig. 7 shows beginning forging die and the finisher of the aluminium alloys for automobile pull bar of the present invention.As it is shown in fig. 7, beginning forging die and
Finisher is integrated design, and beginning forging die die cavity is positioned at the left side of finisher die cavity.Beginning forging die includes beginning forging die 703 and lower forging of beginning
Mould 704, when forging die of upper beginning 703 and lower beginning forging die 704 close, can bend blank blocking by aluminium alloys for automobile pull bar of the present invention
Become required form.Finisher is positioned at the right side of beginning forging die, including upper finisher 705 and lower finisher 706, when upper finisher 705
When closing with lower finisher 706, the aluminium alloys for automobile pull bar of the present invention can be bent blank and be configured to finally drawing of band overlap
Bar.
6th step: the final pull bar of band overlap is shipped back electric screw press 207 by manually or mechanically hands, by putting
Overlap on the aluminium alloys for automobile pull bar of band overlap is removed by the described edger on electric screw press 207, thus
Prepare final aluminium alloys for automobile pull bar.
The most as shown in Figure 6, edger is arranged at the right side of electric screw press 207 work top, and edger includes
Edger 605 and lower edger 607, be positioned over the aluminium alloys for automobile pull bar of band overlap in lower edger 607, upper edger
605 descending time, the overlap on aluminium alloys for automobile pull bar can be removed, thus prepares final aluminium alloys for automobile pull bar.
During the aluminium alloys for automobile pull bar trimming of the present invention, owing to the temperature of this pull bar is higher, during trimming, deposit
Cut crossing, tear and the defect such as burr is excessive, therefore, it is generally the case that after the aluminium alloys for automobile pull bar of band overlap is cooled down
Trimming.Before trimming, by the pull bar of band overlap by cooling by water to room temperature, then, on electric screw press 207, logical
Cross edger 605 and the cutting burrs of the pull bar of band overlap is fallen by lower edger 607, thus obtain final car aluminum and close
Gold pull bar.
As it has been described above, the aluminium alloys for automobile pull bar manufacturing process automaticity of the present invention is high, convenient, fast.
It will be appreciated by those skilled in the art that direction term herein such as: on " ", D score, "left", "right", " front "
