Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a tungsten carbide alloy cutting tool. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-made. Since the cutting tools used in mechanical manufacturing are basically used for cutting metal materials, the term "cutting tool" is generally understood as a metal cutting tool. Cutting tools used for cutting wood are called woodworking tools.

[0003] In the field of machining, the performance of cutting tools directly affects machining efficiency, machining accuracy, and workpiece quality. Traditional cutting tools have certain shortcomings in terms of tool head installation convenience, heat dissipation performance, and positioning stability. For example, the tool head installation structure is complex, which makes tool head replacement time-consuming and laborious, reducing machining efficiency; poor heat dissipation will cause the tool head temperature to be too high, accelerating tool wear, affecting machining accuracy, and shortening tool life. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a tungsten carbide alloy cutting tool, including a tool holder 1, a tool head 2 movably disposed above the tool holder 1, a mounting handle 3 fixedly disposed below the tool head 2, a chip removal groove 4 fixedly disposed on the tool head 2, a mounting port 5 fixedly disposed above the tool holder 1, a limiting chamber 6 fixedly disposed on the inner side of the tool holder 1, a positioning pad 7 fixedly disposed on one side of the inner side of the limiting chamber 6, a limiting ring 8 fixedly disposed on the outer side of the tool holder 1, and a screw fixedly disposed on the inner side of the limiting ring 8. A threaded rod 9 is fixedly provided with an adjusting handle 10 on one side and a clamping plate 11 on the other side. A partition 12 is fixedly provided on the inner side of the handle 1. A connecting sleeve 13 is fixedly provided above the partition 12 and a circulating pump 14 is fixedly provided below the partition 12. A heat dissipation pipe 15 is provided on the inner side of the mounting handle 3. A guide pipe 16 is provided at the liquid outlet end of the heat dissipation pipe 15. The heat dissipation pipe 15 and the guide pipe 16 are respectively connected to the liquid outlet end and the liquid inlet end of the circulating pump 14.

[0026] The mounting handle 3 is adapted to the mounting port 5, allowing it to be inserted into the port 5 to achieve a movable connection between the blade head 2 and the handle 1. The limiting chamber 6 cooperates with the positioning pad 7, which provides positioning and cushioning for the mounting handle 3 installed within the limiting chamber 6. The threaded rod 9 is threadedly connected to the limiting ring 8. When the adjusting handle 10 is rotated, the threaded rod 9 can move linearly within the limiting ring 8, causing the clamping plate 11 to move closer to or away from the positioning pad 7. The inner diameter of the mating sleeve 13 is adapted to the outer diameter of the mounting handle 3. After the mounting handle 3 is inserted into the mating sleeve 13, the gap between them does not exceed 0.5mm. The heat dissipation pipe 15 is spirally wrapped around the inner side of the mounting handle 3 to increase the heat dissipation area. The guide pipe 16 is a flexible pipe that can move with the movement of the mounting handle 3. With a certain degree of bending, the circulation pump 14 is a miniature centrifugal pump that can draw back the liquid that has absorbed heat in the heat dissipation pipe 15 through the guide pipe 16 and pump it back into the heat dissipation pipe 15 for circulation and heat dissipation. During the cutting process, the heat generated by the cutting head 2 is absorbed by the liquid in the heat dissipation pipe 15. The miniature centrifugal pump, i.e., the circulation pump 14, starts and draws back the liquid that has absorbed heat through the guide pipe 16 and pumps it back into the heat dissipation pipe 15 for circulation and heat dissipation. By setting a spiral heat dissipation pipe 15 inside the tool holder 3, and cooperating with the circulation pump 14 and the flexible guide pipe 16, efficient circulation and heat dissipation are achieved, which effectively reduces the temperature of the cutting head 2 and extends the tool life. The chips generated during the machining process are discharged in time through the chip discharge groove 4 to avoid chip accumulation affecting the machining quality and tool life.

[0027] Working principle: When using this tungsten carbide alloy cutting tool, when installing the tool head 2, align the tool holder 3 with the installation port 5 and insert it. The tool holder 3 enters the limiting chamber 6, where the positioning pad 7 provides initial positioning and cushioning. Subsequently, rotate the adjusting handle 10, causing the threaded rod 9 to move linearly within the limiting ring 8, bringing the clamping plate 11 closer to the positioning pad 7, thus firmly clamping the tool holder 3. Simultaneously, the tool holder 3 is inserted into the docking sleeve 13 to ensure installation stability. This enables rapid installation and removal of the tool head 2 and tool holder 1, greatly improving the efficiency of tool head 2 replacement and reducing downtime during processing. This process improves processing efficiency. During the cutting process, the heat generated by the cutting head 2 is absorbed by the liquid in the heat dissipation pipe 15. The micro centrifugal pump, i.e., the circulation pump 14, is started to draw the heat-absorbing liquid back through the guide pipe 16 and pump it back into the heat dissipation pipe 15 for circulation and heat dissipation. By setting a spiral heat dissipation pipe 15 inside the tool holder 3, and cooperating with the circulation pump 14 and the flexible guide pipe 16, efficient circulation and heat dissipation are achieved, effectively reducing the temperature of the cutting head 2 and extending the tool life. The chips generated during the processing are discharged in time through the chip discharge groove 4 to avoid chip accumulation affecting the processing quality and tool life.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
