Abstract
The present invention changes the lock clamp manufacture from original single turning and single milling process into a stamping process. The stamping process makes the lock clamps uniform in size and any one pair of lock clamps match well. The less change in size caused by motor and friction results in less increased air valve interval and improved performance of the engine.
Description
The present invention relates to a kind of method of making the engine valve locker.
Valve collet is the strength member of internal combustion engine key component valve location, and the minor variations of these part overall dimensions will cause the increase of air distribution system valve clearance to cause the motion noise to increase.The locker that present domestic internal combustion engine industry is used is turning and processes, the external form rough surface, and the turning process complexity, the locker quality of match is poor, causes combustion engine powered performance to descend, and suddenly waits to change processing method commonly used at present.
Purpose of the present invention is exactly the problem that exists at present locker turning processing, and a kind of new processing method of development.
The object of the present invention is achieved like this, the manufacturing process of locker is changed into punch forming process by original single-piece turning, the single-piece milling skill that goes into operation, its manufacture method is: with the finish rolling of raw material bar is section bar, the section bar punching is the blank of moulding locker with shape, blank is put into shaping mould strike out locker, then the locker surface is polished and Quenching Treatment, its technological process is: bar, and---------locker---polishing---quenches blank section bar.
Owing to adopt the punch forming manufacture method, make locker overall dimensions high conformity, any two lockers coupling in pairs are tight, and metal structure is fine and close more, and overall dimensions change minimumly during the motion friction, make the valve clearance be difficult for increasing, and have improved the performance of engine.
