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 for metal materials, in particular to a surface strengthening treatment technology for a bicycle front fork. Background technique [0002] With the improvement of people's living standards, bicycles, as a healthy and green means of transportation, are increasingly attracting people's attention, and higher requirements are also put forward for the quality of bicycles. As an exposed component, the side of the front fork close to the wheel often Affected by the stones brought up by the wheels, and the outside is exposed to the wind and the sun for a long time, the paint is prone to peel off, and the metal layer of the seat post is exposed and corroded, which affects the driving safety. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a process for strengthening the front fork of a bicycle. [0004] The technical sc...
