Description
Technical field
Hot extrusion one-shot forming axle tube mould belongs to the extrusion die technical field, is specifically related to the one-time formed mould of a kind of hot extrusion.
Background technology
Axle tube is commonly called as spindle nose; Be the major part of bearing load on the truck back axle, early stage axle tube adopts casting usually, carries out following process then; Because of the blank dense structure of casting not enough; And possibly also have various casting flaws, bad mechanical property has been a kind of almost by the technology of eliminating fully; Existing forge die because the axle tube size is elongated, and is a hollow structure; Can only forge the axle tube cylindrical; Endoporus can't forge, and difficult forming is more in the forging process, and blank adds holes and the car hole to it man-hour; The aperture can't guarantee, is difficult to guarantee that machining accuracy and wall unevenness are even.
Existing automotive axle axle tube of China and engineering machinery bridge end bearing axle adopt vertical hot die forming or multimode hot extrusion molding technology mostly, and this process operation needs heating-die mould-shallow dashing-a plurality of operations such as deep-draw in process, so the corresponding equipment of usefulness that needs is more; Need an equipment like die mould; Shallow dashing needs an equipment, and deep-draw needs an equipment, promptly accomplishes two of whole machining process process needs or the moulding of three equipment ability; Therefore; Problems such as this technology not only exists work flow long, and stock utilization is low, and have many defectives such as technological process is complicated, workpiece turnover work step is many, labour intensity is big, the workpiece heat loss is bigger.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, a kind of die life length, simple, the uniform hot extrusion one-shot forming of the workpiece wall thickness axle tube mould of technological process are provided.
The utility model solves the technical scheme that its technical problem adopted: this hot extrusion one-shot forming axle tube mould; It is characterized in that: comprise drift, drift fixed head, counterdie and knife edge die; The drift top connects the hydraulic press movable slider through the drift fixed head; Counterdie is inner for being provided with the cavity of step, and knife edge die is installed in the bottom in the counterdie cavity.
Described drift one end is installed drift fixed head, the tapered setting in the other end.Through the disposable machine-shaping of drift, the inner metal grain even structure that forms of workpiece, refinement and flowline are smooth, and Fiber Distribution and sleeve pipe vertical consistency can improve plasticity, impact flexibility and the fatigue resistance of axle tube, have prolonged service life.
Be provided with in the described knife edge die and the corresponding cavity of counterdie intracavity diameter.
Compared with prior art, the beneficial effect that the utility model had is:
1, simple in structure, easy to operate: as mainly to form by several parts such as counterdie, workpiece and drifts; With pushing in the movable slider entering counterdie of drift through hydraulic press; The disposable machine-shaping of hot extrusion, the metal grain even structure that interior forms, refinement and flowline are smooth, and Fiber Distribution and sleeve pipe vertically are consistent; Not only improve plasticity, impact flexibility and the fatigue resistance of axle tube, and prolonged the service life of axle tube significantly.
2, reduced processing step, shortened technological process, procedure of processing is simpler; Reduced operator's labour intensity, workpiece need not other turnover work step, and the heat loss of workpiece is little; And can guarantee the even of wall thickness of boring a hole; Not only be easy to processing, and very save material, solved the difficult problem of endoporus processing in the actual production in the past.
Description of drawings
Fig. 1 is the annexation cross-sectional schematic of the utility model drift and drift fixed head.
Fig. 2 is that the utility model workpiece is installed in the front view cross-sectional schematic in the counterdie.
Wherein: 1, drift 2, drift fixed head 3, counterdie 4, knife edge die 5, workpiece.
Fig. 1～2nd, the most preferred embodiment of the utility model further specifies below in conjunction with 1～2 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1～2:
This hot extrusion one-shot forming axle tube mould; Comprise drift 1, drift fixed head 2, counterdie 3 and knife edge die 4, drift 1 one ends are installed drift fixed head 2, the tapered setting in the other end; The middle part is provided with step; And drift 1 top is through the movable slider of drift fixed head 2 connection hydraulic presses, and counterdie 3 is inner for being provided with the cavity of step, and the step position in the cavity is corresponding with the step of workpiece 5; Knife edge die 4 is installed in the bottom in counterdie 3 cavitys, is provided with in the knife edge die 4 and the corresponding cavity of counterdie 3 inner chamber lower diameter.
The course of work is following:
The utility model is at first put into workpiece 5 inner chamber of counterdie 3 in use, and the workpiece 5 of this moment is the axle tube semi-finished product, and counterdie 3 is adjusted; The quick compacting of the counterdie of adjusting 3,, drift 1 slowly is pressed in the workpiece 5 along with the continuous compacting of hydraulic press with the hydraulic press movable slider; When the clout in workpiece 5 endoporus is filled up first step of workpiece 5, reach travel position, all the other clouts cut off with knife edge die 4; Hydraulic press rises, and the hydraulic press movable slider is got back to initial position, throws into the clout that cuts off on one side; Through liftout tank workpiece 5 is ejected from the inner chamber of counterdie 3 again, can accomplish an operation cycle, prepare to carry out next operation cycle.
Processing step is few, and technological process is brief, has reduced operator's labour intensity; Workpiece need not other turnover work step, and the heat loss of workpiece is little, and the metal grain even structure that interior forms, refinement and flowline are smooth; Fiber Distribution and sleeve pipe vertically are consistent; Can guarantee the even of wall thickness of boring a hole, not only improve plasticity, impact flexibility and the fatigue resistance of axle tube, and prolonged the service life of axle tube significantly.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
