Abstract
The invention discloses a kind of method for processing sector gear, include the following steps：It is 190 200 DEG C of valve plate die cavitys to take precoated sand to inject temperature by penetrating sand machine, and heat preservation is so that precoated sand curing molding, molding obtain working plate；Gear blank finishing is by together with the good fan-shaped gear blank of roughing and working plate clamping, and first with working plate endoporus clamping, smart car working plate and excircle of workpiece reserve mill allowance；Then clamping is carried out using working plate and excircle of workpiece, smart car working plate and inner hole of workpiece, reserve mill allowance, greatly improve the dimensional accuracy of gear, 6 grades of national standard or more is reached, preparation method of the invention ensures that the stabilization of sector gear metallographic structure, production cycle shorten 50% or more, 60% or more improving productivity, production cost reduce by 50% or more；Perfect technology can ensure the quality of gear, reduce rejection rate, the problem of resource waste of effective solution enterprise.
Description
Technical field
The present invention relates to machine components technical field more particularly to a kind of method for processing sector gear.
Background technology
With the rapid development of science and technology, sector gear is widely used in various radar trackings monitoring systems at present
It is therefore, more demanding to the accuracy class of sector gear in gear assembly, generally all in 6 grades of national standard or more, it is necessary to use
Roll flute processing can be only achieved profile accuracy class requirement, and application of the sector gear in machine driving and entire machinery field is extremely
Extensively, however the processing technology of prior art middle gear and not perfect, cause the gear quality produced undesirable, be not achieved
Requirement, high rejection rate cause unnecessary waste to enterprise.
Invention content
In consideration of it, the present invention provides a kind of method for processing sector gear, include the following steps：
The first step：It is 190-200 DEG C of valve plate die cavity to take precoated sand to inject temperature by penetrating sand machine, and heat preservation is so that precoated sand solidification
Molding, molding obtain working plate；
Second step：Gear blank finishing is by together with the good fan-shaped gear blank of roughing and working plate clamping, first with working plate endoporus
Clamping, smart car working plate and excircle of workpiece, reserve mill allowance；Then clamping, essence are carried out using working plate and excircle of workpiece
Turner loading board and inner hole of workpiece reserve mill allowance；
Third walks：By the good fan-shaped gear blank of roughing and tooling board clamping, cast cavity is formed；
4th step：Tooth form roughing loads onto gear hobbing mandrel and carries out gear hobbing, and common normal stays 0.2~0.8mm of mill surplus；5th, tooth form
Finishing loads onto roll flute mandrel roll flute to design parameter requirement；
5th step：The Pair test or final inspection of finished product sector gear：Examine by drawing its geometric accuracy, contact zone,
Noise；It is matched on rolling checking machine, examines contact zone position, size and shape, and examine noise, mark is stamped by coupling gear
Note, is finally antirust and packaging and storage to assemble use in pairs.
The present invention is further described, the temperature in the first step is 195-199 DEG C, and is kept for 20-25 seconds.
The present invention is further described, the combination of the second step sector gear blank and working plate utilizes workpiece dowel hole
With connection threaded hole connection.
Using above-mentioned technical proposal, have the advantages that：
Present invention can ensure that while gear teeth face dimensional accuracy is met the requirements, the high intensity of forming gear is realized, the present invention
Preparation method overcome traditional processing technology caused by rise tooth phenomenon, greatly improve the dimensional accuracy of gear, reached state
6 grades of mark or more, preparation method of the invention ensure that the stabilization of sector gear metallographic structure, production cycle shorten 50% or more,
60% or more improving productivity, production cost reduce by 50% or more；Perfect technology can ensure the quality of gear, reduce useless
Product rate, the problem of resource waste of effective solution enterprise.
