Problems solved by technology

[0002] With the improvement of people's living standards, bicycles, as a healthy and green means of transportation, have increasingly attracted people's attention, and higher requirements have been put forward for the quality of bicycles. Impacted by the stones brought by the wheels, the outside is exposed to wind and sun for a long time, and the paint is prone to peeling off, which exposes the metal layer of the seat post and causes corrosion, which affects driving safety

Abstract

The invention relates to a bicycle front fork enhanced treatment process which includes the steps of sand blasting, heat strengthening, annealing, sol, bonding, cutting, surface filming. The structural strength of a treated bicycle front fork is higher, and the outer surface has a certain buffering capacity, which can reduce an external impact force and abandons a traditional painting process.

Description

technical field [0001] The invention relates to a surface treatment technology of metal materials, in particular to a bicycle front fork surface strengthening treatment process. Background technique [0002] With the improvement of people's living standards, bicycles, as a healthy and green means of transportation, have increasingly attracted people's attention, and higher requirements have been put forward for the quality of bicycles. Impacted by the stones brought by the wheels, the outside is exposed to wind and sun for a long time, and the paint is prone to peeling off, which exposes the metal layer of the seat post and causes corrosion, which affects driving safety. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a bicycle front fork strengthening treatment process. [0004] Technical scheme of the present invention is as follows: [0005] A bicycle front fork strengthening treatmen...
