Problems solved by technology
[0003] From the nickel plating process described above, it is not difficult to find that what the existing process adopts is that only the internal spline is partially nickel plated, and the local nickel plating process requires a high degree of technical know-how as far as the existing situation is concerned (belonging to the knowhow technology ), only individual suppliers will operate, which results in applicants having to rely on individual suppliers for nickel plating, resulting in higher processing costs

Embodiment Construction
[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] The present invention improves the existing partial nickel plating process, which is improved to integral nickel plating, and the overall nickel plating process is specifically referred to figure 1 . From figure 1 It can be seen that a nickel-plating process for the hub of a clutch driven disc includes the following steps in turn: (1) firstly process the raw material hub 1", which has a through center hole in the center, and process it according to the required size The outer peripheral surface of the raw material hub 1 "and the inner surface of the central hole, to obtain a pre-processed hub 1', figure 1 The outer surface of the raw material hub 1" in the axial direction is in the shape of gradually shrinking or expanding steps, ...

The invention relates to a nickel plating process for a clutch driven plate wheel hub. Local nickel plating is replaced with overall nickel plating. According to the nickel plating process for the clutch driven plate wheel hub, the nickel plating process comprises two divided machining steps, that is, the step 1 and the step 4, so that overall nickel plating is possible. Compared with local nickel plating, the overall nickel plating technology is a commonly used technology known to technical personnel in the field, easy to operate and low in cost, and highly technical knowhow is required by the local nickel plating technology which is complex. Compared with the prior art, although one more step (the machining steps is divided into the step 1 and the step 4) is added into the process steps of the nickel plating process, the production cost is greatly reduced due to the fact that local nickel plating is replaced with overall nickel plating.
Description
technical field [0001] The invention relates to a processing technology of a hub of a clutch driven disc, in particular to a nickel plating process of the hub of a clutch driven disc. Background technique [0002] The clutch plate hub is used to connect with the transmission input shaft through an internal spline, which transfers the engine torque from the clutch plate side to the transmission side. Nickel plating on the surface of the internal splines of the driven disc hub increases surface durability and reduces surface wear and corrosion. In the existing nickel plating process, the raw material hub is first machined on the surface, then the flange is pressed and embedded on the processed hub to form the hub assembly, and then the inner spline is processed in the hub center hole of the hub assembly , and then perform partial nickel plating, that is, nickel plating only on the inner spline to improve the wear resistance and corrosion resistance of the inner spline surface...
