Abstract
A rear axle casing for (10-13)-ton truck is characterized by that there is an R arc at relative position of internal cavity and end flanges, and the reinforcing boss with oil hole is positioned on radical central line of said rear axle casing. It is made through the casting step including proportioing, melting, casting, removing sand, annealing and antirusting, and the machining step including turning, milling, boring, drilling, screwing, pressing sleeve pipe and milling support arm. Its advantages are simple structure, high mechanical performance and simple technology.
Description
Technical field: the present invention relates to a kind of 10-13 ton back axle shell for heavy truck and processing technology thereof.
Background technology: 10 tons of higher level heavy goods vehicles back axles of tradition adopt alloy steel punching press welded structure, and the processing technology difficult point is many, and manufacturability is poor, quality be cannot say for sure card, and high temperature resistant, low cold can on have open defect: easily curved during high temperature, lowly easily produce brittle failure when cold.I mention in application number is the application for a patent for invention of 01033672.2 back axle shell for heavy truck and adopt casting method to make back axle shell for heavy truck, but do not say concrete manufacture craft.
Summary of the invention: the present invention is in order to solve the problem of conventional heavy-duty car rear-axle casing processing technology complexity and manufacturability difference, a kind of 10-13 ton back axle shell for heavy truck and processing technology thereof are proposed, the die cavity of this rear-axle casing is inner to be provided with the R radian with two end flanges opposite positions, the boss that plays booster action is positioned on the radial centre lines of described rear-axle casing, on the described boss oil through is arranged; Its processing technology comprises foundry technique and mechanical processing technique; Described foundry technique is: batching-fusing-casting-sand removal-annealing-surface is antirust; Described mechanical processing technique is: car flange and oil sealing rim of the mouth-combination end face milling-bore hole-boring, tapping-gland pipe-mill supporting arm.This axle housing is simple in structure, good mechanical property, and technology is simple, and easy to process, good manufacturability.
Description of drawings: Fig. 1, this invention 10-13 ton back axle shell for heavy truck structural representation.
The specific embodiment: as shown in Figure 1, the die cavity of this back axle shell for heavy truck 1 is inner to be provided with R radian 3 with two end flanges, 2 opposite positions, its arc length 80-150mm, and purpose is to strengthen the bearing capacity of whole bridge, be positioned at 4 booster actions of boss on the rear-axle casing radial centre lines, oil through 5 is arranged on the boss 4.Its processing technology is: earlier with the sand removal annealing of casting after the spheroidal graphite iron fusing, be processed into blank by foundry technique, pass through mechanical processing technique again: car two end flanges and oil sealing rim of the mouth, it is two-sided that the Chinese lute hole is milled in combination, the while bore hole, bore aperture, tapping on flange hole and the Chinese lute, the gland pipe, mill successively the steel plate support, on connect the two-sided and boring of support arm, connect back axle two and hang the two-sided and boring of booms.Check is at last put in storage.This mechanical performance of products is good: specific impulse weldering axle housing intensity is big 1.4 times, and cushioning performance strengthens 1.8 times, and indeformable under hot operation, and low temperature subzero 30 is spent not cold cracking.
Claims (3)
