Abstract
The invention discloses a manufacturing method of a welded steel pipe-free integrally formed automobile transaxle housing, comprising the steps of blanking, reducing, squaring and opening technology holes, heating and extruding, reforming and forming. When in blanking, a seamless steel tube with the diameter of 140mm and the thickness of 8mm is adopted and is intercepted into a required tube blank for blanking based on that the bridge shell length is 1650mm; when in reducing, the tube blank is pressed to a tube blank with a big middle part and two small end parts on a hydraulic press; and after the steps of squaring and opening technology holes, heating and extruding and reforming, circular tubes at two ends are shrunk into three stepping circular tubes respectively with the diameter of 115mm, 110mm and 80mm. The method in the invention only performs local machining on a steel tube material, realizes manufacturing of the seamless transaxle housing, and has simple manufacture process, fewer procedures and simple method; the bridge shell tube wall has no massive thinning phenomena; the forming process has no adverse influence on the product materials; and the axle housing has light weight, reliable technical properties, high material utilization rate, low cost and high processing efficiency.
Description
Technical field
The present invention relates to the manufacture method of the manufacture method of automobile transaxle housing, particularly a kind of welded steel pipe-free integrally formed automobile transaxle housing.
Background technology
One of critical piece of the automobile of driving axle housing, it is the main component parts of power train, is again the main component parts of running gear, and mainly to act on be to support and protection main reducing gear, differential mechanism and semiaxis etc. to driving axle housing in power train; In running gear, driving axle housing mainly acts on the relative axial position that is driving wheels and fixes, with driven bridge support frame and on each assembly quality.Simultaneously, when running car, bear road surface reaction and moment that left and right wheels transmits, and pass to vehicle frame through the suspension body, therefore, driving axle housing should have enough intensity and rigidity, the totle drilling cost of driving axle housing accounts for 1/6 of drive axle assembly---and 1/5, therefore the appropriate design of axle housing and economic manufacturing is to guaranteeing the drive axle performance and reduce cost to have crucial meaning.
At present, the forming method of vehicle driving axle housing mainly contains casting and punching press-welding fabrication.Casting bridge shell is to become the intermediate hollow frame with malleable cast iron, the steel axle tube that install in order to hub bearing to be installed at two ends constitutes whole drive axle housing, though this axle housing body have can make complex-shaped and desirable, variable wall thicknessization, the advantage that rigidity, intensity are all bigger, but it is big to exist weight, takes that material, power consumption, equipment investment are big, the high wayward and follow-up machining amount of casting technique difficulty is more and shortcoming such as complexity, and casting bridge shell belongs to first generation axle housing product; Punching press-welding fabrication is to utilize two block plates to strike out the relative welding of two halves axle housing body main part up and down to make required axle housing.At present in automobile industry in the highest flight, applied widely, punching press-welding fabrication axle housing belongs to second generation axle housing product.But the axle housing main part that this manufacturing process obtained is difficult to accurately coincide, and need before the welding to rest and reorganize, and weld seam is long, the welding job amount is big, to welding quality requirement height, otherwise is difficult to guarantee the housing quality, influence its technical performance, and this manufacture method stock utilization is low.
Be the cancellation weld seam, improve technology, guarantee the housing quality, it is 200310110535 " not cast integrally formed automobile transaxle housing manufacture method " that Chinese patent discloses a kind of number of patent application, this drive axle housing comprises that middle casing and section are circular central siphon, middle casing extends to form the central siphon at two ends to two ends, central siphon and middle casing are the integrative-structure of no weld seam global formation, middle casing Chinese lute shape cut-away section is a rectangle, the both sides section of Chinese lute shape part is a square, and circular Chinese lute shape hole is arranged on two wide facades of Chinese lute shape part.Though this manufacture method improves to some extent than said method, there is heating for multiple times in the production process, the manufacturing process more complicated, technical performance is unreliable, the manufacturing cost height.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and a kind of manufacture method of welded steel pipe-free integrally formed automobile transaxle housing is provided, with the driving axle housing body technique dependable performance that this method is produced, manufacturing process is simple, operation is few, the stock utilization height, low cost of manufacture.
Technical scheme of the present invention is: a kind of manufacture method of welded steel pipe-free integrally formed automobile transaxle housing comprises blanking, undergauge, perfect square and opens the step of fabrication hole, squeezed bulging, shaping, shaping:
Blanking: select the seamless steel pipe of 102mm * 8mm-140mm * 10mm respectively for use by axle housing different model specification, cut the pipe blanking by axle housing length 1100-1340mm and form required pipe;
Undergauge: on hydraulic press, pipe is pressed into by axle housing different model specification broad in the middle, the pipe of the little shape in two;
Perfect square and open fabrication hole: on hydraulic press, whole pipe broad in the middle, that two is little is pressed into rectangular tubular, and form the microscler technology through hole of a 200mm*300mm on two its longitudinal center lines of opposite planar upper edge in the middle of the rectangular tubular, make the rectangular tubular pipe;
Squeezed bulging: the rectangular tubular pipe is heated, and with the circular hole of the squeezed bulging of microscler technology through hole in the middle of it to diameter 550mm, two ends are the rectangular tubular of 90mm*90mm, form the circular arc transition between centre and the two ends, make pipe;
Shaping: pipe is carried out shaping, makes its two ends become two stairstepping pipe shapes of big (a diameter 200mm) little (diameter 120mm) by rectangular tubular, and with middle two relative planes between form arc transition, make pipe;
Be shaped: the pipe after the shaping is proofreaied and correct shaping, and the pipe at two ends carries out shrinkage cavity and forms three different stepped pipe shapes of diameter, product of the present invention.
The further technical scheme of the present invention is: during undergauge, on hydraulic press pipe is pressed into mid diameter 120-170mm by axle housing different model specification, the pipe of two diameter 80-110mm shape.
The present invention does not have the manufacture method of welding integrally formed automobile transaxle housing, just the partial operation of steel pipe material is shaped, realized the manufacturing of no weld seam driving axle housing body, manufacturing process is simple, operation is few, method is simple, the axle housing tube wall does not have a large amount of attenuation phenomenons, forming process can not cause harmful effect to product material, improved the technical performance of this drive axle housing, axle housing is in light weight, compared with prior art, dependable performance possesses skills, the stock utilization height, low cost of manufacture, energy-conservation, economize characteristics such as material, working (machining) efficiency height.
