Production process of motorcycle valve spring under high-temperature and high-frequency working conditions

The invention discloses a production process of a motorcycle valve spring under high-temperature and high-frequency working conditions. The process comprises the following steps: step 1, selecting and detecting raw materials; secondly, the raw materials obtained in the first step are subjected to cold rolling forming to form a spring; thirdly, the spring obtained after cold rolling forming is subjected to stress relief tempering; fourthly, the two ends of the spring obtained in the third step are ground; fifthly, the two ends of the spring obtained in the fourth step are chamfered; sixthly, the spring obtained in the fifth step is subjected to shot blasting treatment; seventhly, the spring obtained in the sixth step is subjected to surface nitriding treatment; eighthly, the spring obtained in the seventh step is subjected to two times of shot peening strengthening treatment; ninthly, the spring obtained in the eighth step is subjected to hot prestressing treatment; tenthly, the spring obtained in the ninth st
