Problems solved by technology

In the prior art, after upsetting the blank, the practical forming die completes the forming of the product at one time, which has the following significant technical defects: 1. The material does not flow sufficiently, and the product flow line is discontinuous, resulting in low fatigue strength of the product , cracks are prone to appear during use; 2. The forming die is seriously worn out and the service life is shortened

Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The forging process of the hub unit flange provided by the present invention will be further described in detail below,

[0030] Please refer to figure 2 , in a specific embodiment of the present invention, it comprises the following steps in sequence:

[0031] 1. Blanking is to prepare a cylindrical hot-rolled steel billet. The diameter and length of the billet are determined according to the product size, mold size and equipment. The weight of the blanking is controlled at 1.12 to 1.18 times the weight of the finished product.

[0032] 2. Spheroidizing annealing refers to softening the billet. The spheroidizing annealing process specifically includes:

[0033] Heating: The billet is heated to 800°C at a heating rate of...

Abstract

The invention provides a forging process of a hub unit flange plate. The process comprises flows of unloading, annealing, upsetting, surface treatment, forward extrusion, pre-molding, formation, punching and heat treatment in sequence. In the forging process of the hub unit flange plate, two extrusion procedures of forward extrusion and pre-molding are added before formation; on the one hand, fullflowing of materials can be guaranteed to improve continuity of a product production line; and on the other hand, the load of a forming mold can be reduced to prolong the service life of the formingmold.

Description

technical field [0001] The invention relates to the field of forging of auto parts, in particular to a forging process of a wheel hub unit flange. Background technique [0002] The hub unit flange is the key component of the automobile hub unit. Please refer to Figure 1a and Figure 1b ,in: Figure 1a A structural schematic diagram of a hub unit flange is shown, Figure 1b for Figure 1a top view, such as Figure 1a and Figure 1b As shown, the flange of the hub unit includes a shaft part 1 and a connecting disc 2 formed on the upper part of the shaft part 1. Several flange holes 3 are pierced on the connecting disc 2, and a special-shaped installation is formed in the shaft part 1. Hole 4. [0003] In the prior art, the forging process of the hub unit flange includes the following steps in sequence: blanking, annealing, upsetting, extrusion forming, and heat treatment. In the prior art, after upsetting the blank, the practical forming die completes the forming of the ...
