Abstract
The invention discloses a novel forging process of a vehicle rear wheel hub axle and a special wedge-shaped die thereof. The process comprises the following specific flows of: (1) heating procedure: heating an initial blank to 1,000-1,300 DEG C; (2) blank manufacturing procedure: manufacturing the heated initial blank into a blank through a roller and a wedge-shaped die, reasonably allocating the volume of the blank to obtain two symmetrical prefabricated blanks and ensuring that the shapes of the prefabricated blanks more conform to a forging die impression; (3) segmenting procedure: segmenting and separating the two symmetrical prefabricated blanks; (4) die forging procedure: continuously deforming the prefabricated blanks to obtain a final forged piece; and (5) trimming procedure: cutting trimmings to obtain a final qualified forged piece. In the whole process flow, a product can be forged and molded only with once heating and once die forging, thus the process has the advantages of simple procedures, fewer turning numbers of times, raw material saving, energy consumption reduction and production efficiency improvement.
Description
Technical field
The present invention relates to metallic element and forge processing technique field, especially a kind of automobile back wheel hub axle new technique for forging and special-purpose wedge shape mould thereof.
Background technology
The rear-wheel hub axle is mainly used in kart, and it links together automobile axle, back wheel brake system and trailing wheel, is the important spare part of automobile.Because the rear-wheel hub axle needs very high intensity, toughness, mechanical property and dimensional accuracy, and rear-wheel hub axle construction changes of section is big, so shaping can not be once heated in upright forging, needs post bake, its technology is generally: heating → die forging → car overlap → heating → die forging → side cut → shaping.This arts demand carries out blank twice heating, twice die forging and removes overlap twice, and operation is loaded down with trivial details, and stock utilization is low, wastes energy waste of manpower, poor product quality.
Summary of the invention
Technical assignment of the present invention is at not enough in the above-mentioned technology, and automobile back wheel hub axle new technique for forging and special-purpose wedge shape mould thereof are provided.
The technical scheme that technical solution problem of the present invention is adopted is: automobile back wheel hub axle new technique for forging, may further comprise the steps, and (1) heating process is about to initial blank and is heated to 1000 ℃---and 1300 ℃; (2) preforming, the initial blank after being about to heat is by the roll base, and the volume of reasonable distribution blank obtains two symmetrical prefabricated blank, makes the prefabricated blank shape meet the forging die impression; (3) cut off operation, the prefabricated blank cut-out that is about to above-mentioned two symmetries is separated; (4) die forging operation obtains finish-forging spare even above-mentioned prefabricated blank continues distortion; (5) side cut operation is promptly excised overlap and is obtained final qualified forging.
Automobile back wheel hub axle new technique for forging, its special equipment is a wedge shape mould, this wedge shape mould is divided into pan feeding section A, wedging section B, broadening section C, Strain During Finishing Stage D shears section E and discharging section F.
Also used wedge shape mould in the described preforming, to guarantee more to be met the prefabricated blank of forging die impression.
The beneficial effect that the present invention can bring is:
One, through an once heating and a die forging, the product forging and molding can be compared with common Forging Technology, had that operation is simple, the circulation number of times is few, save raw material, cut down the consumption of energy, enhance productivity;
Two, improve product quality, made product obtain better streamline, strengthened mechanical performance of products, anti-fatigue performance, prolonged service life.

The substep that Fig. 2 is shaped for the present invention's blank in the base process (broadening, finishing and cut off for three steps) amplification front elevation and side view;
Fig. 3 is the expansion view of wedge shape mould among the present invention;
Fig. 4 is the view of wedge shape mould among the present invention with the roll base.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done following detailed description:
The invention discloses automobile back wheel hub axle new technique for forging shown in top accompanying drawing, may further comprise the steps, (1) heating process is about to initial blank 2 and is heated to 1000 ℃---and 1300 ℃; (2) preforming, the initial blank 2 after being about to heat is by roll 1, wedge shape mould 3 bases, and the volume of reasonable distribution blank obtains two symmetrical prefabricated blank 4, makes prefabricated blank 4 shapes meet the forging die impression more; (3) cut off operation, prefabricated blank 4 cut-outs that are about to above-mentioned two symmetries are separated; (4) die forging operation obtains finish-forging spare even above-mentioned prefabricated blank 4 continues distortion; (5) side cut operation is promptly excised overlap and is obtained final qualified forging.
Automobile back wheel hub axle new technique for forging, its special equipment is a wedge shape mould 3, this wedge shape mould 3 is divided into pan feeding section A, wedging section B, broadening section C, Strain During Finishing Stage D, shears section E and discharging section F, and the concrete use of this wedge shape mould 3 is as follows: the initial blank 2 after at first will heating is sent into the pan feeding section A of wedge shape mould 3; Initial blank 2 rotation is got up, and realize that the wedge top is raised to the wedging section B that wedge is risen by above freezing; Make under roll 1 effect of circular blank in rotation at broadening section C, promptly under the ramp effect of two symmetrical wedges, realize that radial compression extends axially distortion; Finish final shaping and guarantee required precision by Strain During Finishing Stage D, make prefabricated blank 4 can better meet the forging die impression; An E finishes cutting off of two prefabricated blank 4 material in the shearing section; Two prefabricated blank 4 material after cutting off are introduced discharging section F.
After wedge shape mould 3 uses, then the prefabricated blank 4 of discharging section is put into the forging die impression, make prefabricated blank 4 continue distortion and obtain finish-forging spare; The operation of cutting edge again at last, the excision overlap obtains final qualified forging.Whole process flow only needs once to heat and a die forging can be with the product forging and molding, advantages such as operation is simple, the circulation number of times is few, save raw material, cut down the consumption of energy, improve production efficiency and product quality, make product obtain better streamline, strengthen mechanical performance of products, anti-fatigue performance, prolonged service life.
