The drill bit is an important tool for oil drilling, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost F1. The design of the three-cone bit is mostly based on practical experience, combined with the method of trial and use, and the design and calculation are carried out repeatedly, so the design accuracy is low, the cycle is long, it is difficult to improve the design quality, and only one drill bit can be designed for each calculation, and the efficiency is low. Therefore, it is very necessary to develop a CAD system for the three-cone drill bit and realize the parametric drawing of the three-cone bit. 1. The overall design of the system, the three-cone bit parametric drawing system adopts the functional modular programming method, and the whole system is divided into four functional modules: user interface management module, drill bit tooth surface structure design module, database management module, and parametric drawing module. The design of the user interface is implemented by the VBA secondary development tool embedded in AutoCAD. The user enters the relevant parameters of the three-cone bit design through the user interface module to realize the human-machine information exchange. The main function of the drill bit tooth surface structure design module is to complete the complex design data calculation of the third cone bit according to the design theory of the three-cone bit. The database management module is a database built by Access 2003 in the form of data tables.

Features:
1. Floating bearing structure is adopted, and the floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated with solid lubricant. While reducing the relative linear velocity of the bearing pair, the temperature rise of the friction surface can be reduced, which can effectively improve the bearing life and bearing reliability under the condition of high drilling pressure or high speed drilling process.
2. Adopt high-precision metal seal. The metal seal consists of a pair of well-designed and machined metal sealing rings as the axial dynamic seal of the bearing, and two highly elastic rubber energy supply rings are located in the sealing area of the tooth palm and cone respectively as static seals, and the optimized sealing compression ensures that the sealing surfaces of the two metal rings are always in good contact.
3. The steel ball locks the cone wheel to adapt to high speed.
4. The all-rubber oil reservoir that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system provides a good lubrication guarantee for the bearing system.
5. Adopt a new type of grease that can withstand high temperature of 250°C and resist wear.
6. The toothed drill bit is made of high-strength and high-toughness cemented carbide teeth, and the optimized design of the number of tooth rows, the number of teeth, the height of the tooth and the unique alloy tooth shape give full play to the high wear resistance and excellent cutting ability of the toothed drill bit. The new wear-resistant material of the tooth surface welding of the steel tooth drill bit improves the cutting tooth life of the drill bit while maintaining the high mechanical penetration rate of the steel tooth drill bit.
