Carbide drills with ultra-fine particles, the average size of tungsten carbide phase grains are below microns. This drill not only has high hardness but also has improved compressive and flexural strength. In order to save costs Many drills now use a welded shank structure. The original drill is made of cemented carbide as a whole. Now the rear drill is made of stainless steel, which greatly reduces the cost. However, due to the use of different materials, the dynamic concentricity is not as good as that of the solid carbide drill. Especially in terms of small diameters. The drill bits are generally made of cemented carbide, because the epoxy glass cloth clad copper foil plate wears very fast. The so-called cemented carbide is based on tungsten carbide powder and contains % cobalt. Because of its high hardness High, very wear-resistant, with constant strength, suitable for high-speed cutting. But poor toughness, very brittle, in order to improve the performance of cemented carbide. Some use chemical vapor deposition layer ~ micron super hard titanium carbide on the carbide substrate (TIC) or titanium nitride (TIN) to make it have higher hardness. Some use ion implantation technology to implant titanium, nitrogen, and carbon into their substrates to a certain depth-depth, which not only improves the hardness and strength, but also in drill These infused components can also migrate inwards during head regrinding. Others use physics to form a diamond film on the top of the drill bit, which greatly improves the hardness and wear resistance of the drill bit. The hardness and strength of cemented carbide are not only related to the ratio of tungsten carbide and cobalt, but the commonly used types in mines are different types, types, types, and those used by drilling teams are larger, useful, and so on. Production environment to buy a blast furnace drill that is suitable for you. How does a blast furnace drill work? During digging, the drill bit rotates around the vertical axis and moves axially at the same time. The soil is cut under the action of the torque and axial force of the drill bit, and is pounded and broken up under the action of the extrusion and centrifugal force of the working blade, and at the same time, it is lifted to the surface along the page. When the soil flow moves to the place where there is no pit wall block, the soil flow is formed and pressed to the pit wall, and the broken soil is thrown away due to the centrifugal force. At the same time, it is also used for coal shearer drilling tools, mining machinery tools and road cleaning, snow removal and road maintenance. tool.

The teeth of the rhinestone drill bit are applied with automatic innovation, which can be reused many times, and the service life is twice that of the ordinary drill bit, which reduces the production cost. The blast furnace taphole bits widely used in iron and steel smelting still use mine rock drilling bits. Most of them are welded by electric welding of flake alloy and drill body, or are assembled by cold pressing of stud alloy and drill body through interference fit, and also made of flake alloy or stud alloy and drill body. Welded by ordinary brass solder, the shape is basically wing-shaped or wing-shaped, and the wing-shaped or wing-shaped drill bit will be prematurely passivated or the shear force will drop due to the fixed tooth area occupying most of the area of ​​the head of the drill body. Due to the different expansion coefficients of the alloy and the drill bit body under high temperature conditions, the drill bit using the column tooth alloy cold pressing makes the gap between the column tooth alloy and the cylindrical blind hole too large, which causes the column tooth alloy to lose teeth and the drill bit is scrapped; Due to the poor shear strength and low melting point of ordinary brass solder under high temperature conditions, the stud alloy will fall off, so the slag discharge groove is small. Due to the wear of the alloy, the whole drill bit has a short service life, is scrapped in advance, and increases the operating cost. SUMMARY OF THE UTILITY MODEL A two-wing type blast furnace drill bit of the present invention includes a base with a central hole and a wing body formed with the base, the top of the base is provided with a top air hole, and the between the wing body and the first wing body is provided.

The angle between the slag discharge groove between the two wings of the base head and the center line of the base is -°. The inclination angle of the side clearance surface is °-°, which reduces the resistance of the drill bit and increases the slag discharge effect. With accurate positioning, stepped graded footage. The service life is double that of ordinary drill bits, which improves work efficiency, reduces production costs, and saves valuable tungsten-cobalt alloy resources. The toughness of the drill bit can break rocks and rocks, and it is an indispensable mechanical product in the mining industry. Such as drilling, opening oil wells, etc. can be used everywhere: the drill bit. Then the drill bit will always be worn during use, and it needs to be ground before it can continue to be used. How is the drill bit done? Before grinding the drill bit, the main cutting edge of the drill bit should be placed on a horizontal plane with the grinding wheel surface, that is, to ensure that the entire edge should be ground when the cutting edge contacts the grinding wheel surface. This is the step of the relative position of the drill bit and the grinding wheel. After the position is set, slowly move to the grinding wheel surface and lean. The angle at which the axis of the drill bit is inclined to the surface of the grinding wheel. What are the technological breakthroughs and advancements in the manufacturing of this angle rhinestone bit tooth processing? It is the sharp angle of the drill bit. The wrong angle at this time will directly affect the size of the top angle of the drill bit, the shape of the main cutting edge and the bevel angle of the chisel edge. This refers to the positional relationship between the drill bit axis and the surface of the grinding wheel, just take it, this angle can be seen more accurately. Here we should pay attention to the relative horizontal position and angular position of the drill bit before sharpening, which should be taken into consideration. The blast furnace drill includes a plurality of cutting edge portions arranged at the tip end of the drill bit, and a shaft-shaped drill main body provided on the base end side of the cutting edge portion and having a shank portion formed on the base end portion. The bare and raw steel pipes are made into drill pipes after several processing steps. First of all, through the processing of the steel pipe thickening process, the outer surface of the light pipe is bent inward, and the wall of the steel pipe is thickened. Next, threading and plating can increase! Enhanced strength copper. However, non-destructive quality inspection is carried out, and the welding of steel pipe body joints is carried out. Then, the tube body undergoes a welding heat treatment and a welding process to relieve welding residual stress. Other inspections of the finished steel pipe, including hardness testing, pressure testing and non-destructive testing, are performed before the finished drill pipe is painted and packaged. The length of the drill pipe is generally about meters. Self-propelled bolt construction and step-by-step construction preparation The construction site is laid flat manually or mechanically, so that the bolt drilling rig can be driven, in and out. Set up a work platform or erect a scaffold according to the needs of the operation. Connect various pipes and water pipes, keep various pipes unobstructed, air compressor drives and grouting hands and windlass drives in place, air compressors. , Anchor winch grouting pump, mortar mixer testing machine without failure, prepare various materials. After the hole air compressor is started, turn on the rock bolt drilling rig and adjust the drilling angle of the rock bolt drilling rig according to the terrain and geological conditions. According to the geological conditions, determine the length of the bolt to splicing the bolt on site. When drilling the partial anchors, secure the rear set of anchors to the rear of the front part of the anchor with manually applied lubricant until each anchor is drilled to the desired length. Grout bolt end pump through. Quick grout joint connection, prepare cement and other mixed materials according to the mixing ratio, and feed the mixture into the mixer to stir the water. The amount of grouting is determined according to the pressure of the grouting pump or according to the consumption rate of the mortar mixer. Immediately after the grout is complete, the stopper is installed and then secured. Arched pads are placed on the exposed portion of the anchor and adhere tightly to the surface or rock layer. The ball nut is placed on the outside of the pad. After the work is finished drilling and grouting, various mechanical equipment; scaffolding; and then the site is cleaned. Drill pipes are often broken due to the following reasons. If the drilling speed is too high, the drill pipe will be inappropriately bent due to the centrifugal force, resulting in wavy fluctuations. Or due to the excessive loosening of drilling tools, the weight of all drilling tools becomes the WOB, so that the stress on the drill pipe reaches the damage limit; the fishtail drilling tools are used for drilling into the cobble layer or other hard rock layers, and the rotation speed is not appropriate.

There is a lot of resistance in drilling tools Blind drilling in the case of blind drilling, the drill pipe is damaged due to the torque exceeding the limit it can bear; after the hole collapses, the drilling tool is buried, without taking appropriate measures and measures according to the specific situation, blindly lifting the drilling tool, blast furnace Wholesale drill bits, blast furnace opening drill, head, opening machine drill bit, blast furnace drill manufacturer quality assurance. Promotions are in progress, welcome new and old customers to come to consult. After the drill pipe is broken, different measures should be taken according to the specific conditions in the hole. Before dealing with the accident, you should first find out the situation of the drill pipe in the hole. Generally, you should use a printer to print it first, and then take different measures according to the following different situations. In this case, if the drill pipe is not buried by the silt, and the upper end is provided with a drill pipe coupling, the drill pipe can be lowered to test the connection thread, and if it can be firmly connected, it can be raised. If there is a certain inclination at the upper end of the drill pipe, use the fishing hook to straighten it, clamp the drill pipe coupling, and then lift it out. You can also use the hook to straighten first and then use: the circlip sleeve clamps the drill pipe coupling and lifts it out. The toughness of the blast furnace bit can break rock and rock, and it is an indispensable mechanical supply in the mining industry. Such drill bits can be used everywhere such as drilling, drilling oil wells, mining mines, etc., as well as blast furnace opening machines. Then the drill bit will always be worn during use, and it needs to be ground before it can continue to be used. How is the drill bit done? Bending and Vibration. In the process of oil and gas exploration and refining, the product performance is not as stable as that of the new melt, nor can it meet the hardness requirements of the new melt. The main problems of my country's cemented carbide industry are that the scale of the enterprise is small and the industrial concentration is not high. According to statistics, the average annual production capacity of tungsten carbide enterprises is ton-. M volume crushing stage: when the drilling pressure is added to more than the hardness of the rock, the cutting teeth will cut into the rock to produce volume crushing, and the drilling effect will be obvious. Wear gloves, and do not stand on the line with the palm and shovel person to prevent the hammer from hurting people and preventing accidents. u The shock-absorbing ring assembly plays the role of protecting the main engine. Once the rubber of the shock-absorbing ring assembly is broken, falling off, aging, and the rapid drop of the drill pipe, it will smash the main engine, and the drill pipe will be used. It is necessary to ensure that the rubber of the shock absorber ring assembly is basically intact. yX It is necessary to know that the blast furnace drill bit will be worn for a long time, and drilling for a long time will make the drill bit smooth, so the number of regrinding should be increased. In general, the wear depth of the full length of the cutting edge within two days should be less than .mm. When regrinding, the .mm should be removed. Traditional fixed shank bits can be resharpened one time, and spade bits can be resharpened twice. Overgrinding will reduce the drilling quality and accuracy, causing the PCB product to be scrapped. Over-grinding can be counterproductive.
