Description

A kind of application of the grinding device of the ultra-thin circular knife of hard alloy
The present patent application is divisional application, parent application number:2014107756842;Female case title:A kind of hard alloy surpasses The grinding device of thin circular knife;Parent application day:On December 15th, 2014.
Technical field
The invention belongs to produce the process units technical field of hard alloy, and in particular to a kind of ultra-thin dise knife of hard alloy The application of the grinding device of piece.
Background technology
Hard alloy introduces China from the sixties in last century, and current China has become the first in the world CEMENTED CARBIDE PRODUCTION With consumption big country.Hard metal article has the excellent performance comparable to diamond, and higher quality is brought to people’s lives Conveniently, it has been deep into the every aspect of people's life.
With the fast development and progress of society, the use scope of cutter is also gradually expanding, small to arrive daily life product etc. The manufacture of light industry, the big figure that all can't do without cutter to fields such as the heavy industry such as building, military affairs, synchronous, tool sharpening neck The development in domain is also increasingly rapid.
In recent years, knife, which cuts hardware products industry, larger development, and export trade volume is increasing year by year, according to statistics, I State is engaged in knife and cuts the enterprise of production there are about 3,000, and the total industrial output value of scissors products year is about at more than 100 hundred million yuan, year foreign exchange earning More than 400,000,000 dollars.Day common hardware products such as kitchen knife, set knife, pocket knife, Stupalox and industrial scissors, Scissors, tailor Scissors etc., because that must there is quite high hardness just to can reach its sharpness and durability, so grinding technics will be passed through mostly To reach the sharp requirement of section and cutting edge, geometric dimension requirement and appearance requirement.
Larger tool sharpening is mostly ground using blade knife sharpener in carbide chip, but small, thickness surpasses Thin and without magnetic metal the ultra-thin circular knife of hard alloy cannot then use blade knife sharpener to be ground, according to routine techniques hand Section, this blade is not only not easy to clamp, is also easy to be injured blade idiosome by grinding stress, be more not achieved required roughness, The high-precision requirements such as flatness, the depth of parallelism and blade angle are well ground this requires one kind can protect blade idiosome and have The device for grinding effect occurs.
Chinese Patent Application No.:201420208481.0 publication date:The patent document of 2014-4-25 discloses a kind of point Carving knife adsorbs grinding attachment without magnetic vacuum.Absorption clamping device in the utility model include wheel disc, absorption bistrique and Vacuum shaft, absorption bistrique are located at vacuum shaft right end, and wheel disc is fixedly connected with vacuum shaft;Water butt upper end is set there are two nozzle, vacuum Pump is connected with a nozzle of water butt by pipeline, another nozzle of water butt passes through pipeline and absorption clamping device Vacuum shaft is connected, and the wheel disc adsorbed on clamping device is connect by belt with motor;Absorption bistrique is provided with absorption ring, inhales Follower ring is equipped with adsorption hole, and adsorption hole is evenly arranged on absorption ring, and the central area for adsorbing ring is positioning column, and absorption clamps dress The vacuum shaft inner hollow put, vacuum shaft inside are connected with adsorption hole.The utility model vacuum suction fixes the mode of blade It is safe and efficient, it not only ensure that the efficient polishing of blade, but also solve the problems, such as that blade grinding stress generates damage to blade.The reality With novel in the process of lapping for being applied to ultra-thin circular knife, blade often occur, slightly loosening causes to grind uneven and report It is useless, it is since ultra-thin circular knife is relatively light and too thin, the adsorption capacity of the utility model is not as good as belt transmission through analyzing its reason Shaking force influence big, and adsorption capacity is not uniform enough, and local adsorption capacity is small.
Invention content
1. technical problems to be solved
It is not easy to clamp during dise knife slice lapping ultra-thin for hard alloy in the prior art, existing grinding device adsorption capacity is not The problem of enough uniform, the present invention provides a kind of applications of the grinding device of the ultra-thin circular knife of hard alloy.The device can be real Now uniformly securely clamp the purpose that the ultra-thin circular knife of hard alloy is ground.
2. technical solution
