Problems solved by technology

[0002] During the running of the car, due to the unevenness of the road surface, the tires and hubs will be subjected to complex external forces. There are the following problems: due to long-term bumps or different driving habits, the hubs are prone to breakage during the running of the car, which will cause the car to exercise safety issues
[0004] However, due to the modification of the structure of the rim, the overall structure of the hub is complicated, which is easy to cause inconvenience in installation and use.

Abstract

The invention belongs to the technical field of automobile accessories, and particularly relates to a manufacturing method of a high-strength alloy hub. The manufacturing method of the high-strength alloy hub comprises the following steps that A, carbon fibers are made into a strip shape with the diameter not larger than 1 cm; B, carbon fiber strips are inserted in a penetrating manner from fine holes in the periphery of a hub die, and then are downwards inserted from the fine holes in the top surface of the hub die until abutting against the bottom surface inside the hub die; C, an aluminum alloy solution is injected into the hub die with the carbon fiber strips penetrating thereinto, and cooling and molding is performed; D, the portions, exposed out of the hub die, of the carbon fiber strips are cut by using an ultrasonic cutting device; E, a formed aluminum alloy hub is taken out from the hub die, and secondary cutting is performed on the hub by using a water cutting device; and F,the aluminum alloy hub obtained in the step E is polished, and film coating is performed on the outer surface of the aluminum alloy hub with activated carbon. According to the manufacturing method, the appearance of the manufactured hub is the same as that of a traditional hub, however, the strength of the hub is very high, and the phenomenon that the hub is broken is avoided.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a method for manufacturing a high-strength alloy wheel hub. Background technique [0002] During the running of the car, due to the unevenness of the road surface, the tires and hubs will be subjected to complex external forces. There are the following problems: due to long-term bumps or different driving habits, the hubs are prone to breakage during the running of the car, which will cause the car to Exercise safety issues. [0003] In the traditional technology, in order to increase the strength of the wheel hub, the method of changing its physical structure is adopted. For example, the technical content disclosed in Chinese patent CN106427378A: a high-strength wheel hub, including a rim, a hub and a main spoke; on the inner hole wall of the rim, Near the right side of the rim, there is a boss protruding radially; one end of the main spoke is connected to the outer wall of ...
