Abstract

The invention belongs to the technical field of auto parts, in particular to a method for manufacturing a high-strength alloy wheel hub. A method for manufacturing a high-strength alloy wheel hub, comprising the following steps: A. making carbon fibers into strips with a diameter not greater than 1 cm; B. inserting the carbon fiber strips through the pores around the wheel hub mould, The fine hole on the top surface is inserted downward until it touches the bottom surface inside the hub mold; C. Inject the aluminum alloy solution into the hub mold with carbon fiber strips, and cool and form; D. Use an ultrasonic cutting device to clean the exposed hub mold E. Take out the formed aluminum alloy wheel hub from the wheel hub mold, and use the water cutting device to carry out secondary cutting on the wheel hub; F. Polish the aluminum alloy wheel hub obtained in step E, and use activated carbon to it The outer surface is coated. The appearance of the wheel hub produced by the invention is the same as that of the traditional wheel hub, but its strength is very high, and the situation of fracture will not occur.

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 ...
