Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a hardened tungsten steel tool specially used for cutting on high-speed machines. Background Art

[0002] High-speed machining is an advanced cutting technology that achieves efficient machining of parts through high spindle speed and fast feed rate.

[0003] Compared with traditional cutting, high-speed machining can significantly improve production efficiency, reduce processing costs, and can process more complex parts.

[0004] The spindle speed of a high-speed machine is usually from several thousand to tens of thousands of revolutions per minute, or even higher, which enables the cutting edge to process the material at a higher linear speed, thereby improving processing efficiency.

[0005] High-speed machine cutting has a wide range of applications, including aerospace, automobile manufacturing, mold manufacturing, precision machinery and other fields.

[0006] Through high-speed machining, various metal and non-metal materials can be efficiently processed, such as aluminum, steel, cast iron, plastic, wood, etc. In addition, high-speed machining can also achieve complex surface processing, such as curved surfaces, helical gears and propellers.

[0007] When high-speed machine cutting, tungsten steel tools are generally used. They are cutting tools made of tungsten steel (hard alloy). Tungsten steel is a hard alloy sintered by mixing tungsten carbide particles and cobalt or other bonding metals. It has high hardness, wear resistance and heat resistance, so it is very suitable for cutting processing.

[0008] At present, most cutting tools are in the form of a single cutter head with a single function, which can only meet the shape cutting processing of a single point of the material, especially corner cutting and hole cutting. When a single object needs to be processed at non-fixed points, the tool needs to be replaced frequently, which is time-consuming and labor-intensive, and greatly reduces work efficiency. Utility Model Content

[0009] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a hardened tungsten steel tool for high-speed machine cutting.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] A hardened tungsten steel tool specially used for high-speed machine cutting is designed, comprising a blade body, the blade body being a cylindrical structure, the surface of the blade body being provided with an external threaded surface, the end of the blade body being provided with an integrally formed blade head, the surface of the blade head being provided with a grinding surface, the surface of the blade body being provided with a discharge channel, and one end of the discharge channel is fitted with the end of the external threaded surface, a baffle is provided on the outer ring wall of the blade body, and the discharge channel runs through the interior of the baffle, and the other end of the blade body is provided with a mounting hole running through the interior thereof.

[0012] When it is necessary to dock with the tool holder of a high-speed machine, the blade body is inserted into the tool holder, and the locking bolt on the tool holder passes through the mounting hole to achieve stable installation of the blade body and the tool holder. When the tool holder of the high-speed machine rotates, the blade body is driven to rotate. When cutting corners, the cutter head structure contacts with the object to achieve stable corner cutting. When it is necessary to drill a hole, the end of the cutter head contacts with the object to achieve drilling, and stable material discharge is performed through the external thread surface to avoid blockage of debris when drilling. At the same time, the discharge channel can improve the discharge effect of waste materials.

[0013] In detail, the blade and the blade head are both made of tungsten steel material. The hardness of tungsten steel is usually 89-93hra, which is equivalent to about hra90, which makes it have good wear resistance and can keep the tool edge sharp during high-speed cutting. Due to the high hardness of tungsten steel, its wear resistance is also very good, which means that the tool will wear more slowly during the processing process, thereby extending the service life of the tool. Tungsten steel tools can withstand very high temperatures, so they can work at higher cutting speeds, and are not prone to softening and annealing.

[0014] In detail, the number of the blade heads is four, and the blade heads are evenly distributed on one end surface of the blade body.

[0015] In detail, the grinding surface is composed of a tooth structure.

[0016] In detail, there are two discharge channels, and the discharge channels are symmetrically distributed along the outer wall of the blade body. The discharge channel is actually a chip groove structure. The chip groove can guide the chips out of the cutting area to prevent the chips from accumulating between the tool and the workpiece, causing damage to the machined surface, tool wear or thermal damage to the workpiece. Through the rapid discharge of chips, the chip groove helps to reduce the heat-affected zone of the tool and the workpiece, thereby reducing thermal deformation and improving machining accuracy. Effective chip removal can reduce the wear and damage of the chips to the tool and extend the service life of the tool. Good chip removal can reduce the scratches and contamination of the chips on the machined surface of the workpiece, thereby improving the surface quality.

[0017] In detail, the baffle is an annular plate structure, and the inner wall of the baffle is slidably sleeved with the surface of the blade body and the connection is fixed by welding.

[0018] In detail, the inner wall surface of the mounting hole is a threaded surface or a smooth surface, and the mounting hole is a round hole structure.

[0019] The design scheme proposed by the utility model has the following beneficial effects during application:

[0020] 1. Through the cooperation of the cutter head structure and the external thread surface, the corner cutting and hole cutting of the object can be realized in one operation, avoiding the frequent replacement of tools due to different cutting forms, and can adapt to the cutting forms of different positioning of the same object, thereby improving the cutting efficiency of the object.

[0021] 2. The cutter head part adopts four single-body cutter heads, and adds tooth structure on the outer surface of the cutter head, which can perform more precise operations for some precise trimming. At the same time, the four single-body structures can be removed and replaced after a single one is worn out. Compared with the situation where the whole cutter head has a gap, maintenance is faster and simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-Figure 5A hardened tungsten steel tool specially used for high-speed machine cutting includes a blade body 10. The blade body 10 is a cylindrical structure. The surface of the blade body 10 is provided with an external thread surface 11. The end of the blade body 10 is provided with an integrally formed cutter head 12. The surface of the cutter head 12 is provided with a grinding surface 13. The surface of the blade body 10 is provided with a discharge channel 14, and one end of the discharge channel 14 is in contact with the end of the external thread surface 11. A baffle plate 15 is provided on the outer ring wall of the blade body 10, and the discharge channel 14 runs through the interior of the baffle plate 15. The other end of the blade body 10 is provided with a mounting hole 16 running through the interior thereof.

[0030] It should be further explained that the blade body 10 and the blade head 12 are both made of tungsten steel material. The hardness of tungsten steel is usually 89-93hra, which is equivalent to about hra90, which makes it have good wear resistance and can keep the tool edge sharp during high-speed cutting. Due to the high hardness of tungsten steel, its wear resistance is also very good, which means that the tool will wear more slowly during the processing process, thereby extending the service life of the tool. Tungsten steel tools can withstand very high temperatures, so they can work at higher cutting speeds, and are not prone to softening and annealing.

[0031] It should be further explained that there are four cutter heads 12, and the cutter heads 12 are evenly distributed on one side end surface of the blade body 10. The cutter head 12 part adopts four single-body cutter heads, and a tooth structure is added to the outer surface of the cutter head 12, which can perform more precise operations on some precise comparative trimming. At the same time, the four single-body structures can be removed and replaced after a single one is worn out, which is faster and simpler to repair than the situation where the entire cutter head 12 has a gap.

[0032] It should be further explained that the grinding surface 13 is composed of a tooth structure, and through the cooperation of the cutter head 12 structure and the external thread surface 11, it can realize the integrated operation of corner cutting and hole cutting of the object, avoiding the frequent replacement of tools due to different cutting forms, and can adapt to the cutting forms of different positioning of the same object, thereby improving the cutting efficiency of the object.

[0033] It should be further explained that there are two discharge channels 14, and the discharge channels 14 are symmetrically distributed along the outer wall of the blade body 10. The discharge channels 14 are actually chip groove structures. The chip grooves can guide the chips out of the cutting area to prevent the chips from accumulating between the tool and the workpiece, causing damage to the machined surface, tool wear or thermal damage to the workpiece. By quickly discharging the chips, the chip grooves help reduce the heat-affected zones of the tool and the workpiece, thereby reducing thermal deformation and improving machining accuracy. Effective chip removal can reduce the wear and damage of the chips on the tool and extend the service life of the tool. Good chip removal can reduce the scratches and contamination of the chips on the machined surface of the workpiece, thereby improving the surface quality.

[0034] It should be further explained that the baffle 15 is an annular plate structure, and the inner wall of the baffle 15 is slidably connected to the surface of the blade body 10 and the connection is fixed by welding, which can prevent debris from flying in the direction of the connection between the blade body 10 and the blade seat when opening a hole.

[0035] It should be further explained that the inner wall surface of the mounting hole 16 is a threaded surface or a smooth surface, and the mounting hole 16 is a round hole structure, which can be matched with a screw or a bolt, so as to be plugged and fixed with the tool holder part of the high-speed machine.

[0036] Working method: When it is necessary to dock with the tool holder of the high-speed machine, the blade body 10 is inserted into the tool holder, and the locking bolt on the tool holder passes through the mounting hole 16 to achieve stable installation of the blade body 10 and the tool holder. When the tool holder of the high-speed machine rotates, the blade body 10 is driven to rotate. When cutting corners, the cutter head 12 structure contacts with the object to achieve stable corner cutting. When it is necessary to drill a hole, the end of the cutter head 12 contacts with the object to achieve drilling, and stable material discharge is performed through the external threaded surface 11 to avoid blockage of debris when drilling. At the same time, the discharge channel 14 can improve the discharge effect of waste materials.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
