Embodiment Construction

[0013] Such as Figures 2 to 3 As shown, the manufacturing process steps of the semi-shaft casing of the present invention are as follows: 1. Blanking with round steel with a weight of 25 kg; 2. Heating the round steel with medium frequency induction to a predetermined temperature of 1200 ° C; 3. Forging with a swing roller Machine pre-forging, namely figure 1 State as shown; 4. Then use 800 tons of special hydraulic press to form a one-time die forging to figure 2 In the state shown, the inner hole is fully penetrated and reaches the required size. The misalignment between the outer circle and the inner hole is not more than φ0.4, and the machining allowance is small, which reduces the processing procedures and man-hours, and greatly saves tool consumption and processing man-hours.

[0014] From the comparison of the two processes, the new process can save 10kg of material for the half-shaft parts of the same specification, and use a special 800-ton hydraulic press to forge...

Abstract

The invention relates to a manufacturing technology for a half-axis sleeve tube, and the manufacturing technology comprises the following steps: blanking; forging; performing normalizing treatment; performing mechanical fine machining; performing quenching and tempering treatment; and performing the mechanical fine machining. In the manufacturing technology, a heating and forging method comprises the following steps: 1) mid-frequency inductively heating a round steel material to be at a preset temperature of 1100 DEG C to 1200 DEG C; 2) using a rolling forging machine to pre-forge and form; and 3) using a special 800-ton frame type hydraulic press to perform once die-forging forming treatment and completely running through an inner hole. According to the manufacturing technology, a processing process and labor hours are reduced, a tool cost is saved, a forged piece is free from any burr, the use ratio of materials can reach 99%, and the production efficiency and product quality of the half-axis sleeve tube are increased.

Description

technical field [0001] The invention relates to a production and manufacturing process of an automobile half shaft casing, belonging to the technical field of automobile parts processing. Background technique [0002] The half-axle bushing is an important security part on the rear axle of the car. During the driving process of the car, the half-axle bushing bears the weight of the entire body and the cargo on board. At the same time, due to changes in road conditions, it also bears various complicated alternating stress. Therefore, the forging quality of the half shaft casing is of great significance to ensure the driving safety of the vehicle and improve the economic benefit. [0003] The steps of the traditional manufacturing process of half-shaft casing are: 1. Round steel blanking; 2. Heating the round steel with a coal furnace to a predetermined temperature of 1000°C-1200°C; 3. Upsetting and presetting with an air hammer or friction press Forging and final forging rou...
