Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a vibration-resistant cutting tool. Background Art

[0002] The tools used in metal cutting, namely cutting tools, consist of a cutting part and a clamping part. According to the differences in the workpiece processing surface, this type of tool can be further subdivided into various types, including but not limited to tools for processing external surfaces, hole processing tools, thread processing tools, gear processing tools and cutting tools.

[0003] A Chinese patent discloses a cutting tool (authorization announcement no. ), this patented chip breaker plays a role in chip breaking during cutting, and the chips flow out through the chip breaker; the chip dividing grooves in the chip breaker can change the bending frequency of the chips, avoiding the phenomenon that the chips cannot be broken after being bent multiple times in the chip breaker; multiple chip dividing grooves are arranged at intervals to avoid excessive chip breaking.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the machining process, the cutting tool must have a certain degree of shock resistance. This is because relative displacement may occur between the tool and the workpiece during the cutting process. This phenomenon is defined as chatter. Chatter will cause displacement marks on the surface of the workpiece, thereby seriously affecting the quality of the workpiece; the cutting tools in current technology generally lack sufficient shock resistance, which not only reduces the machining efficiency, but also increases the degree of tool wear.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] Reference Figure 1 and Figure 2As shown, the utility model provides a technical solution: a shock-resistant cutting tool, comprising a cutter body 1, a cutter head 2 is installed at the front end of the cutter body 1, the main body material of the cutter body 1 and the cutter head 2 is tungsten steel, the front end of the cutter body 1 is fixedly connected with a connecting threaded rod 3, and a threaded hole 4 is provided at one end of the cutter head 2 close to the cutter body 1, and the connecting threaded rod 3 and the threaded hole 4 are adapted to each other. By adopting tungsten steel as the base material of the cutter body 1 and the cutter head 2, due to its high strength and high hardness characteristics, combined with a high-performance replaceable cutter head 2 design, the precision threaded connection technology is used to ensure the stability of the cutter head 2 in various processing processes. This design significantly improves the durability of the cutter head 2 and effectively reduces the loosening of the cutter head 2 caused by vibration or impact, thereby significantly enhancing the shock resistance of the cutter body 1 and the cutter head 2.

[0022] Reference Figure 3 As shown, in this embodiment: a plurality of chip removal holes 5 are opened on the surface of the cutter head 2. Through the design of the chip removal holes 5, the debris generated during the cutting process can be quickly discharged, avoiding the accumulation of debris in the contact area between the cutter head 2 and the workpiece, thereby reducing the friction and heat accumulation between the cutter head 2 and the workpiece. This design of the chip removal holes 5 not only improves the cutting efficiency, but also extends the service life of the cutter head 2.

[0023] Reference Figure 4 As shown, in this embodiment: a plurality of shock-absorbing washers 6 are installed on the surface of the blade body 1. By carefully designing and installing multiple shock-absorbing washers 6 at specific positions of the blade body 1, the vibration force can be significantly reduced when the blade head 2 is cutting or processing. These shock-absorbing washers 6 can effectively absorb and disperse the vibration energy generated by the movement of the blade head 2, thereby helping to maintain the stability and balance of the blade body 1 and the blade head 2. This design not only improves the service life of the blade body 1 and the blade head 2, but also ensures the accuracy and efficiency of the processing process, further improving the user experience.

[0024] Reference Figure 4 As shown, in this embodiment: the interior of the cutter body 1 adopts a hollow structure design. The core of the hollow structure design concept is to effectively reduce its mass by constructing a cavity inside the cutter body 1. This type of structure is particularly suitable for a cutter body 1 operating in a high-speed rotation environment. Since the mass of the cutter body 1 is significantly reduced, the centrifugal force generated during high-speed rotation acts on the cutter body 1 accordingly. Therefore, the dynamic response performance of the cutter body 1 in the high-speed rotation state is improved, thereby enhancing the stability of the processing process.

[0025] Reference Figure 5As shown, in this embodiment: a groove 7 is provided on the surface of the blade body 1. By providing the groove 7 on the surface of the blade body 1, when the blade body 1 rotates at high speed, the contact surface of the blade body 1 and the blade head 2 will generate heat energy, and the contact between the groove 7 and the air will form an airflow on the surface of the blade body 1. The airflow circulates between the contact surfaces of the blade body 1 and the blade head 2, thereby realizing the heat dissipation function to a certain extent, thereby improving the heat dissipation efficiency of the blade body 1 and the blade head 2.

[0026] Reference Figure 1 As shown, in this embodiment: a number of anti-vibration and sound-absorbing grooves 8 are opened in the position of the blade body 1 near the blade head 2. By carefully designing and arranging a series of anti-vibration and sound-absorbing grooves 8 on the blade body 1, we can significantly improve the anti-vibration performance of the blade body 1. These grooves not only help to absorb and disperse vibration energy, but also effectively reduce the noise generated during use. In this way, the blade body 1 becomes more stable during cutting, grinding or other operations, and its service life is also extended.

[0027] Working principle: By using tungsten steel as the base material of the cutter body 1 and the cutter head 2, due to its high strength and high hardness, combined with the high-performance replaceable cutter head 2 design, the precision thread connection technology ensures the stability of the cutter head 2 in various processing processes. This design significantly improves the durability of the cutter head 2 and effectively reduces the loosening of the cutter head 2 caused by vibration or impact, thereby significantly enhancing the shock resistance of the cutter body 1 and the cutter head 2. The chip removal hole 5 is designed to allow the chips generated during the cutting process to be quickly discharged, avoiding the accumulation of chips in the contact area between the cutter head 2 and the workpiece, thereby reducing The friction and heat accumulation between the cutter head 2 and the workpiece are reduced. The design of the chip removal hole 5 not only improves the cutting efficiency, but also extends the service life of the cutter head 2. By carefully designing and installing multiple anti-vibration washers 6 at specific positions on the cutter body 1, the oscillation force of the cutter head 2 can be significantly reduced when the cutter head 2 is cutting or processing. These anti-vibration washers 6 can effectively absorb and disperse the vibration energy generated by the movement of the cutter head 2, thereby helping to maintain the stability and balance of the cutter body 1 and the cutter head 2. This design not only improves the service life of the cutter body 1 and the cutter head 2, but also ensures the accuracy and efficiency of the processing process. To further enhance the user experience, the core of the hollow structure design concept lies in creating a cavity within the blade body 1 to effectively reduce its mass. This structure is particularly suitable for blade bodies 1 operating in high-speed rotation environments. Due to the significant reduction in the mass of the blade body 1, the centrifugal force generated during high-speed rotation on the blade body 1 is correspondingly reduced. Therefore, the dynamic response performance of the blade body 1 under high-speed rotation is improved, thereby enhancing the stability of the processing process. By providing slots 7 on the surface of the blade body 1, when the blade body 1 rotates at high speed, heat energy is generated at the contact surface between the blade body 1 and the cutter head 2. The contact between the slots 7 and the air creates airflow on the surface of the blade body 1. This airflow circulates between the contact surface of the blade body 1 and the cutter head 2, thereby achieving a certain degree of heat dissipation, thereby improving the heat dissipation efficiency of the blade body 1 and the cutter head 2. By carefully designing and providing a series of anti-vibration and sound-absorbing grooves 8 on the blade body 1, the vibration resistance of the blade body 1 is significantly improved. These grooves not only help absorb and disperse vibration energy, but also effectively reduce noise generated during use. As a result, the blade body 1 becomes more stable during cutting, grinding, and other operations, and its service life is extended.
