Abstract

The invention discloses an overturning casting method for an axle housing of a 30F loader. The method comprises the following steps of: (1) manufacturing a sand core by using thread steel of which the diameter is 20mm as a sand core arbor, filling foam into an axle bag to reduce the weight of the sand core, and forming a flange core head seat of which the diameter is 50mm in the center of a flange surface in the middle of the sand core; (2) manufacturing an upper die cavity, forming a heating open riser at each of two ends of an upper die, forming four heating blind risers in the edge of the flange surface in the middle of the upper die along the circumferential direction, and forming a sand core hoisting channel of which the diameter is 50mm in the center of the flange surface; (3) placing the sand core into the upper die cavity, hoisting the upper die cavity until the upper die cavity is suspended, and locking the sand core; (4) manufacturing a lower die cavity; (5) positioning and installing a core support; and (6) assembling the upper die cavity and the lower die cavity. According to a molding process, the design is reasonable, the flange surface of the cast axle housing is compact without a shrinkage hole, and a sand-hole phenomenon is avoided, so that a phenomenon of oil leakage from a large flange, an oil filling hole and an oil discharging hole in the using process of the axle housing is avoided.

Description

A kind of upset casting method of 30F loading machine axle housing
Technical field
The invention belongs to engineering machinery and truck axle housing manufacture craft technical field, what be specifically related to is a kind of upset casting method of 30F loading machine axle housing.
Background technology
The vehicle traction axle housing is one of key safety parts of heavy vehicle, and it is the main component parts of transmission system, is again the main secure group member of driving system, and driving axle housing is used for supporting and protection main reducing gear, differential mechanism and semiaxis etc. in legacy system; In driving system, driving axle housing is used for the relative axial position of driving wheels is fixed, with driven bridge support frame and on each assembly quality; Simultaneously, when vehicle travels, bear road surface reaction and moment that right wheel transmits, and pass to vehicle frame through the suspension body, therefore, the vehicle axle housing plays crucial effects.
The forming method of vehicle traction axle housing mainly contains casting and punching press-welding fabrication; The casting of prior art mainly exists weight big, and casting process is many, forms sand holes easily, and causes do not fit the fully scarce limit of top box of core in casting mould turnover process easily; Dash in addition-welding fabrication technology, make that axle housing body main part is difficult to accurately coincide, need finishing before the welding, and weld seam is long, the welding job amount is big, and to welding quality requirement height, the utilization rate of material is lower.
Summary of the invention
The objective of the invention is the deficiency at existing conventional cast somatotype technology, a kind of upset casting method of 30F loading machine axle housing is provided, this casting method has the routine of breakthrough, make the cooling procedure of axle housing foundry goods more meet consecutive solidification, thereby make the axle housing significant points, as big flange and oil filler point, drain oil position dense structure, stop characteristics such as oil leakage phenomenon.
The present invention is achieved by the following technical solutions: a kind of upset casting method of 30 loading machine axle housings includes following steps:
(1), the making of core, use diameter as the screw-thread steel of 20mm as the core arbor, be used for strengthening the center intensity of core; At the inner filled and process of bridge bag, to alleviate core weight; The flange core print seat that it is 50mm that flange face center in the middle part of core sets out a diameter, this flange core print seat is buried the metal iron wire underground and is tied to arbor.
(2), go up the making of model cavity, respectively establish a heating open riser in the two ends of mold, the flange face edge at mold middle part along the circumferential direction sets out four heating blind risers, sets out the core passage of codding that a diameter is 50mm simultaneously in the center of this flange face.
(3), in last model cavity, put into core, and make that the metal iron wire is to pass in the core passage of codding of 50mm from the diameter of last model cavity, to go up model cavity and sling, simultaneously at last model cavity downside suspended core metal iron rod will be set, with metal iron wire fixation binding on this suspended core metal iron rod.
(4), the making of counterdie die cavity, be made by normal operation.
(5), the stud of nowel location and installation corresponding specification.
(6), go up model cavity and the mould assembling of counterdie die cavity, will go up earlier after model cavity upset 180 spends, be combined in then on the counterdie die cavity.
Another distortion as production process of the present invention, the center of the patrix flange face in (2) above-mentioned step fixedly installs the steel pipe that a diameter is 50mm, make the suspended core of going up model cavity through this place, and put up placement stud module at the counterdie die cavity, be used for the fixed installation stud.
Beneficial effect of the present invention embodies and is: compared with prior art, moulding process of the present invention, have reasonable in design, casting bridge shell flange face, oil filler point, the fine and close no shrinkage cavity of drain oil, no sand holes phenomenon.
