Abstract
The invention relates to a spindle head molding machine for an integral axle housing of an automobile drive axle. A large-pipe-diameter main shaft is arranged inside a main axle box, a main axle is sued for inserting a to-be-machined steel pipe, the main axle is provided with a clamping device for clamping the to-be-machined steel pipe, and the main axle is fixedly connected with a transmission system; and a machine tool body on two ends of the main axle box is provided with a slide rail, two hydraulic thrusting boxes and a mold box are installed on the slide rail, an axle wire of the two mold boxes is coaxial with the to-be-machined steel pipe. Compared with the prior art, the spindle head molding machine has the advantages of advanced process, reliability in performance, material conservation, low carbon and environmental protection. A product produced by the spindle head molding machine can meet the requirement of the integral axle housing of the heavy truck drive axle, so that the integral axle housing of the automobile drive axle enters the field of the heavy vehicles and engineering vehicles.
Description
Technical field
The present invention relates to a kind of equipment of manufacturing automobile drive axle housing, specifically the special equipment of spindle nose formation rolling in a kind of steel pipe expanding axle housing production, extruding, jumping-up, pulling technology, belongs to shape substantially without machining field shaping technique.
Technical background
At present, the difference of pressing its manufacturing process of producing both at home and abroad, can be divided into three kinds of " casting bridge shell " " steel plate punched welding axle housings " " steel pipe expansion welding spindle nose formula axle housing ".1, cast type axle housing: conventionally adopt spheroidal graphite cast-iron, malleable cast iron or cast steel.With the method for casting, manufacture axle housing blank, then carry out machining and complete product.For further improving its strength and stiffness, the two ends of cast type axle housing are pressed into longer seamless steel pipe and fix as axle tube and with pin.Its major defect is; Castability is wayward, and percent defective is high; Product weight is large, energy consumption is large, contaminated environment; Machined surface is many, and manufacturing process is complicated.Therefore, current cast type axle housing is only for load large heavy-duty car engineering truck and offroad vehicle.2, steel plate punched welded type axle housing: steel plate punched welded type axle housing is to be raw material by mild steel steel plate (16Mn), cut out respectively half shell that punching press (cold moudling or hot-forming) becomes upper and lower two same structures, two halves shell is welded together and becomes axle housing main body, burn-ons respectively with the spindle nose of " flange " and spring perch in two ends.Also there is large, the yielding defect of bonding area in this axle housing.Although adopt several different methods to eliminate stress, effect is undesirable, automobile heavy-load or while travelling on rugged and rough road, axle housing is easily out of shape, leakage of oil, causes axle housing to scrap.Therefore, in heavy goods vehicles field, should not adopt steel plate stamping weldering axle housing.3, steel pipe expansion welding spindle nose formula axle housing adopts the seamless square tube of 16Mn, fluting in the middle of 160*160, and by the process that rolls expansion, make Chinese lute hole forming, square tube two ends cold-extruded is pressed into pipe, then with spindle nose welding.Steel pipe expansion welding spindle nose formula axle housing and steel plate stamping weld the axle housing quality of comparing great changes, although weight is similar with welding axle housing, but intensity and toughness has improved a lot, again because there is no the perforation welding of steel plate stamping weldering axle housing, product internal stress is corresponding minimizing also, having improved axle housing integrated carrying ability, is the good a kind of medium truck axle shell of development prospect.But owing to needing to weld spindle nose in manufacturing process, 16Mn material also cannot improve its bearing strength and ability by heat treatment, and therefore, this vehicle bridge enters heavy field for no reason at all.
Summary of the invention
The invention provides a kind of spindle nose forming machine of automobile drive axle integral housing, the product that the present invention produces, can be able to meet the requirement of Driving Axle On Heavy-duty banjo axle.
Technical scheme of the present invention is: in main spindle box, have Large Diameter Pipeline main shaft, main shaft is for inserting steel pipe to be processed, and main shaft is useful on the clamping device that clamps steel pipe to be processed, and main shaft and transmission system connect firmly; On the lathe bed at main spindle box two ends, have slide rail, two hydraulic thrust casees and die box are loaded on slide rail, and the axis of two die box is coaxial with steel pipe to be processed.
Described clamping device comprises the contract type latch segment that is loaded on main shaft through return spring, is equipped with and promotes contract type latch segment to the slide-and-lock cover moving in main shaft on contract type latch segment, and slide-and-lock cover is connected with locking cylinder.Described clamping device is 6, minute two groups of settings.
Compared with prior art, the present invention has technique advanced person, dependable performance, saving material, low-carbon environment-friendly.The product that the present invention produces, can be able to meet the requirement of Driving Axle On Heavy-duty banjo axle, allows automobile drive axle integral housing enter heavy goods vehicles, engineering truck field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is headstock structure schematic diagram of the present invention.
The specific embodiment
In Fig. 1, have Large Diameter Pipeline main shaft 12 in main spindle box 5, main shaft 12, for inserting steel pipe to be processed 3, has slide rail 4, two hydraulic thrust casees 1 and die box 2 to be loaded on slide rail 4 on the lathe bed 6 at main shaft 5 two ends, and the axis of two die box 2 is coaxial with steel pipe to be processed 3.
In Fig. 2, main shaft 12 in main spindle box 5 connects firmly with transmission system end gear wheel 11, main shaft has clamping device in 12 holes, described clamping device is by locking cylinder 9, slide thrust bearing 10, slide-and-lock cover 8, contract type latch segment 7 forms (two groups totally six of clamping devices, triplets form a clamping unit), through return spring 13, be loaded on main shaft 12.
Using method of the present invention is: label taking standard length hot rolled seamless steel tube; Feeding is to main shaft 12 inner chambers, and location, clamping rotate with main shaft 12; Die box 2 inner molds enter two axial ends, extruding, jumping-up, pulling to determining size shape (spindle nose) along track (axis); Mould is retracted into starting point; Main shaft 12 stops operating, and unclamps clamping device, takes out product.
