Embodiment Construction
[0040] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0041] A method for manufacturing a limit shaft on a floor spring, the method comprising the following steps:
[0042] a. Cutting: cut the next bar blank on a metal bar, and the length of the bar blank is cut according to the design length of the limit shaft;
[0043] b. Shaft body 1 forming: Place the bar blank obtained in step a on a CNC machine tool for machining, so that the bar blank forms a shaft body 1 with a coupling head 1a at one end and a positioning head 1b at the other end, and the coupling head 1a The shape of the hole is the same as that of the hole at the bottom of the door, and at the same time, the convex ring one 1b1 and the convex ring two 1b2 are processed axially on the positioning head 1b;
