Abstract
The invention discloses a machining process for a valve key of an engine, and relates to the technical field of production of metal parts, in particular to a machining technology for parts of an engine. A flat-shaped alloy-steel strip is adopted, the flat-shaped alloy-steel strip can be stamped and deformed on a high-speed punch with a forming die, and the valve key of the engine consistent with the design accuracy is achieved. The formed product can meet the use requirement by only being subjected to outer surface finishing or film coating. The machining process disclosed by the invention has the characteristics of high material utilization rate, high machining efficiency, good production environment and high rate of graded product.
Description
Technical field
The present invention relates to the processing technology of the production technical field of metal parts, particularly engine component.
Background technology
Engine valve lock clamp is used for being arranged between cotter seat and valve stem, and its effect is: under spring force, and cotter seat and valve lever lock are lived.These parts are one of key parts of engine, and its requirement on machining accuracy is high.
Existing valve collet working method has: grind processing three kinds of techniques after numerical control workshop, plunge grinding processing and first car.There is following defect: difficulty of processing is high, be difficult to meet design requirement, processed by profile cutter as adopted, the wear rate of sharpening is high, and not only waste emery wheel but also increase non-cutting time, tooling cost is large.Although the working method of grinding after first car solves the drawback of numerical control workshop and plunge grinding processing, but add one recessing operation in technique, the favourable conditions such as high precision operation blank are provided to slot grinding operation, but need knack work to carry out retrofit, be unfavorable for batch, High-efficient Production, and the consumptive material of above three kinds of techniques is high, waste material spreads all over each position of lathe, cause the severe contamination of production plant, be unfavorable for management.
Summary of the invention
The present invention seeks to a kind of complete processing proposing a kind of engine valve lock clamp that convenience is processed, material use efficiency is high.
The present invention adopts flat alloy strip, once shapingly on high velocity ram machine makes engine valve lock clamp.
In flat alloy strip raw material of the present invention except Fe element, also comprise account for alloy material quality 0.33 ~ 0.38% C, 0.15 ~ 0.35% Si, 0.60 ~ 0.90% the Mn ,≤P of 0.03% ,≤the S of 0.03%, the Cr of 0.90 ~ 1.20%.
The present invention adopts above flat alloy strip can on the high velocity ram machine with shaping die, and a Pressing Deformation, obtains the engine valve lock clamp meeting design accuracy.Product after shaping only need carry out outside surface precision work or plated film just can meet service requirements.Feature of the present invention: material use efficiency is high, working (machining) efficiency is high, and production environment is good, and the percentage of A-class goods is high.
Embodiment
One, equipment requirements:
High velocity ram machine, 80T.
Two, alloy-steel wire prepares:
With containing 0.33 ~ 0.38% C, 0.15 ~ 0.35% Si, 0.60 ~ 0.90% the Mn ,≤P of 0.03% ,≤the S of 0.03%, the Cr of 0.90 ~ 1.20%, all the other are 2.2mm for Fe goes out thickness by die production, and width is the flat alloy strip of 7mm.
Three, mould prepares:
Valve collet forming mould is made by design requirements.
Four, impact briquetting:
The upper and lower mould of valve collet forming mould is separately fixed on high velocity ram machine.
Between the upper and lower mould above flat alloy strip being placed in valve collet forming mould, open high velocity ram machine, after a punching press, obtain a valve collet, by the cooperation of the charging of flat alloy strip and high velocity ram machine action, just multiple valve collet can be obtained efficiently.
Claims (2)
1. a kind of complete processing of engine valve lock clamp, is characterized in that adopting flat alloy strip, once shapingly on high velocity ram machine makes engine valve lock clamp.
2. a kind of complete processing of engine valve lock clamp according to claim 1, to it is characterized in that in the composition of described flat alloy strip except Fe element, also comprise account for alloy material quality 0.33 ~ 0.38% C, 0.15 ~ 0.35% Si, 0.60 ~ 0.90% the Mn ,≤P of 0.03% ,≤the S of 0.03%, the Cr of 0.90 ~ 1.20%.
