[0024] Example:
[0025] like figure 1 As shown, the embodiment of the present invention provides an integral step-type multi-stage oil cylinder processing technology, and the processing technology includes the following steps:
[0026] S1. Prepare thin-walled and thick-walled steel pipes. After preparing thin-walled and thick-walled steel pipes, the thin-walled and thick-walled steel pipes should be tested to indicate whether there is damage, and the qualified thin-walled and thick-walled steel pipes should be pretreated. The treatment method is to finish the surface of the thin-walled steel pipe and the thick-walled steel pipe, so that the finish can reach Ra3.2;
[0027] S2. Process the thin-walled steel pipe into a thin-walled part of a stepped multi-stage oil cylinder (such as figure 1 shown in a);
[0028] S3. Process the thick-walled steel pipe into thick-walled step parts (such as figure 1 shown in b);
[0029] S4. Use friction welding to weld the thin-walled part...
