Abstract
The invention discloses a kind of honing stone for machining steel thin wall chromate treatment cylinder sleeve, the composition of honing stone and percentage by weight be: copper powder 70～80%, glass putty 10～15%, carbonyl iron dust 1～5%, cobalt powder 1～5%, diamond 5～10% (particle size range 100 mesh～300 mesh).By said ratio, raw material is prepared honing stone through batch mixing and vacuum hot-pressing process.Product of the present invention has the advantages that to meet the comprehensive process requirements such as dimensional tolerance, roughness, working (machining) efficiency and service life simultaneously.When invention solves the endoporus of class conventional abrasive material honing stone machining steel thin wall chromate treatment cylinder sleeve, the problems such as the oilstone life-span is short and efficiency is low.
Description
Technical field
The invention belongs to Precision Machining and manufacture field, be specifically related to a kind of honing for machining steel thin wall chromate treatment cylinder sleeve
Oilstone.
Background technology
Owing to, in the physical property of cast iron and price, it is taken as the best material manufacturing cylinder jacket for many years always
Material.But, the market demand requires that engine shop, while not increasing engine total size, increases and sends out all the time
The output of motivation.The most obvious method is through increasing cylinder diameter namely increases cylinder sleeve internal diameter to reach this target.
But owing to being limited by cast iron, wanting to maintain engine total size constancy, the degree increasing cylinder diameter is the most limited.
It is the method solving this problem that application has the steel cylinder jacket of suitable coating protection.Casting is replaced with steel
Iron material, intensity improves 4 times, cylinder displacement can be made to be increased and maintain same stroke, i.e. piston speed is constant, not
In the case of increasing cylinder jacket external diameter and reducing cooling jacket cross section, use steel cylinder sleeve, strengthen cylinder diameter, the merit of electromotor
Rate can increase by 15%.
Machining steel thin wall chromate treatment cylinder sleeve uses the honing stone of conventional abrasive material, and working (machining) efficiency is low, need to frequently change honing
Oilstone.According to the honing stone of super hard abrasive, working (machining) efficiency is high, and the oilstone life-span is long.Invention solves class conventional abrasive material honing oil
During the endoporus of stone machining steel thin wall chromate treatment cylinder sleeve, the problems such as the oilstone life-span is short and efficiency is low.
Summary of the invention
It is an object of the invention to provide a kind of honing stone for machining steel thin wall chromate treatment cylinder sleeve, with steel thin wall
The requirement of the efficient Honing process of chrome-plated cylinder barrel endoporus.This invention solves class conventional abrasive material honing stone machining steel thin wall chromate treatment
During the endoporus of cylinder sleeve, the problems such as the oilstone life-span is short and efficiency is low.
The preparation method of the honing stone of the present invention comprises the following steps:
The composition of honing stone and percentage by weight be: copper powder 70～85%, glass putty 10～15%, carbonyl iron dust 1～
5%, cobalt powder 1～5%, diamond 5～10% (particle size range 100 mesh～300 mesh).
Its preparation technology is as follows:
A, metallic bond and diamond are carried out batch mixing by proportioning；
B, vacuum hotpressing, hot pressing temperature is 650～700 DEG C, and hot pressing time is 2～5 minutes, and pressing pressure is 2～4MPa, vacuum
Degree is 1 × 10-3Pa。
The present invention compares existing product and compares, and has the advantages that
(1) improve the service life of honing stone.The honing stone using superhard material substitutes the honing stone of conventional abrasive material, oil
The service life of stone improves more than 50 times.
(2) honing stone working (machining) efficiency improves.The honing stone using superhard material substitutes the honing stone of conventional abrasive material,
The working (machining) efficiency of oilstone improves more than 1 times.
