Research On Renewable Groovelike Bionic Diamond Bit

Along with human industry and social economy activity flourishing moreand more,the work of breaking rock and ground-breaking that people areengaged in are increasing. It is well known that solid,liquid and gas ore depositcan't do without drilling such as from exploration to exploitation,from the mostloose soil layer to the hardest rock layer.People spend abundant fund andmaterials exploiting underground resources on drilling, therefore if we littleincrease drilling rock efficiency and reduce material resumption, then it willbring about observable economic benefits.This is mypaper's goal.In the biology the spontaneity is the most basic survival function,it Lookslike person's nail to grow unceasingly equally.The spontaneity enable us to beinspired, Applies this idea in the Manufacturing of Impregnated diamond bitthen Conducts the research on biological modelling non-smooth characteristic.Develops one kind of new drill bit-Impregnated boinic diamond bit,it Will behighly effective and unifies wear-resisting.RenLuquan who is in theGround-Mechanical bionics technology laboratory-ministry of education majorlaboratory of Jilin University. After they researched many soil animals, theydevelop all kinds of bionics nonsmooth technology and products such as bionicsplough, bionics nonsmooth mouldboard, which They effectively resolved theconglutination problem of the agriculture and engineering machines. And theyhave extended the nonsmooth theory to many studied like decreasingresistance, wearing and desorption in solid, liquid, gas etc.Biologic nonsmooth's shape includes scale shape, convex closure shape,recess shape, waviness, setaceous shape, etc. In this paper,we conducted apreliminary study on the grooved non-smooth surface an have made aremarkable effect. through the development of non-smooth micro-impregnated bionic diamond drill bit and the genuine drill bit,after a series of indoor tests,wedraw the following conclusions:1,Through theФ25 bionic micro-bit which has radial groove proved that using Diamond particles whose parameter is 70/80 item and concentration for 75%indiamond micro-drill lip to produce non-smooth surface morphology is feasible.At the same time we insert the low degree of hardness N shape material to theWorking-level matrix as to Generate renewable trench.2,The laboratory test ofФ59 bionic drill bit which has radial direction trench tested that radial trench bits'drilling-speed Increased 5.6 and 29.7 times than Pitshape and ordinary drill bit,And it's efficiency is highest in other drillingparameters. according to the experiment,we conclude that the radial directiontrench is not easy to appear and low hardness of the material can not be toomuch.The Non-evenness should be maintained at 30%.3,The laboratory test ofФ59 bionic drill bit which has Concentric-style trench tested that concentric groove in the bit of non-smooth surface can be achieved atthe end of lip.However,this radial material thickness of 1.5mm to reduce thestrength of the matrix, matrix block out the occurrence, the pilot failed toachieve the desired results, but for the next study has provided valuableexperience.4,Through preliminary analysing the mechanism of broken rock andperformance of concentric grooveФ59 bionic bit, we can come to the conclusion that the renewable trench have Significant role in strengthening thecooling effect of the drill bit and increasing the volume of the broken rock, atthe same time, it improves the efficiency of drilling and increase the life of thebit.In this paper,Non-smooth groove is innovatively applied to the design ofthe diamond bit on the base of the anterior fruits,and two bits inФ59 are manufactured in this way. The datas from the laboratory test show that thenon-smooth groove increases the drilling efficiency and the life expectancy,which lays a solid foundation for the groove diamond bionics bit on theformation of non-smooth and the bit processing technology. In this paper, a wide range of means of the design of diamond bionics bit are given, the designfield of the diamond bionics bit is expanded.and a new creative concept is putforward forscientists engaged in bit research.
