Description

Technical Field

[0001] This utility model relates to the field of tap technology, and in particular to a high-performance tap. Background Technology

[0002] In the metal processing industry, taps are a commonly used cutting tool, widely used in the machining of internal threads.

[0003] During operation, taps rapidly accumulate a large amount of heat due to intense friction between the tap and the workpiece material, as well as plastic deformation during cutting. This heat accumulation not only causes a sharp rise in the temperature of both the tap and the workpiece, but also significantly reduces the hardness and strength of the tap material at high temperatures. This directly affects the tap's cutting performance and durability. As the temperature continues to rise, the tap's cutting edge is prone to wear and may even chip, leading to instability in the cutting process and difficulty in ensuring machining accuracy. Furthermore, the thermal expansion effect of the workpiece material is particularly significant at high temperatures, increasing the clearance between the tap and the workpiece, reducing the stability of the cutting process, and posing a serious threat to machining efficiency and product quality. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a high-performance tap to solve the problem that the current taps and workpiece materials are subject to severe friction and plastic deformation during the cutting process, which rapidly accumulate a large amount of heat and pose a serious threat to processing efficiency and product quality.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A high-performance tap includes a shank end, a working end fixed to one end of the shank end, a tapping tool provided on the peripheral surface of the working end, a clamping head fixed to the other end of the shank end, and a heat dissipation hole provided at the center of the working end away from the shank end, and the heat dissipation hole extends into the interior of the shank end.

[0008] Two sets of air intake seats 1 and two sets of air intake seats 2 are fixed on the peripheral surface of the handle end, and each set of air intake seats 1 and air intake seats 2 is distributed in a ring around the handle end. A connecting hole is opened on the peripheral surface of the handle end at the position directly opposite the air intake seats 1 and air intake seats 2, and the air intake seats 1 and the interior of the heat dissipation hole are connected through the connecting hole.

[0009] As an improved technical solution, the first air intake seat and the second air intake seat are the same size. The first air intake seat has a flat end on one side and an arc end on the other side. The flat end has an air inlet channel that communicates with the connecting hole.

[0010] As an improved technical solution, the inlet orientation of the air inlet channel on the first air intake seat is opposite to that on the second air intake seat.

[0011] As an improved technical solution, a heat dissipation core is fixed at the center of the heat dissipation hole, and multiple sets of heat-conducting rods are fixed on the peripheral surface of the heat dissipation core, with the end of the heat-conducting rod away from the heat dissipation core abutting against the inner wall surface of the heat dissipation hole.

[0012] As an improved technical solution, arc-shaped grooves are provided on all four sides of the peripheral surface of the working end, and the arc-shaped grooves cut the tapping tool.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, when the tapping tool taps the workpiece, the heat of the working end and the workpiece will rise rapidly. At this time, the shank end is in a high-speed rotating state. At this time, the airflow in the environment will be poured into the air inlet channel and finally enter the heat dissipation hole through the connecting hole. The airflow entering the heat dissipation hole will dissipate heat on the working end to reduce the temperature of the working end itself.

[0015] 2. In this utility model, a heat dissipation core is installed inside the heat dissipation hole, and it is connected to the working end through the heat conduction rod, which helps to quickly absorb and dissipate the heat on the working end, thereby improving the heat dissipation rate of the working end.

[0016] 3. In the process of tapping the workpiece, this utility model continuously injects airflow into the heat dissipation hole through the flat end, and the continuous airflow dissipates heat from the working end to continuously reduce the temperature of the working end. At the same time, the inlets of the flat ends of the first and second air intake seats are in opposite directions, so both forward and reverse rotation of the shank end can inject airflow into the heat dissipation hole to dissipate heat from the working end, achieving continuous heat dissipation. The heat dissipation core and heat conduction rod assist and accelerate the heat conduction and heat dissipation of the working end, effectively reducing the temperature of the working end during operation and improving the performance of the tap.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0028] like Figures 1 to 4 As shown in the figure, this embodiment provides a high-performance tap, which includes a shank end 1, a working end 2 fixed to one end of the shank end 1, a tapping tool 21 provided on the peripheral surface of the working end 2, a clamping head 5 fixed to the other end of the shank end 1, and a heat dissipation hole 7 provided at the center of the working end 2 away from the end of the shank end 1, and the heat dissipation hole 7 extends into the interior of the shank end 1.

[0029] Two sets of air intake seats 3 and two sets of air intake seats 4 are fixed on the peripheral surface of the handle end 1. Each set of air intake seats 3 and air intake seats 4 are distributed in a ring around the handle end 1. A connecting hole 6 is provided on the peripheral surface of the handle end 1 at the position directly opposite the air intake seats 3 and air intake seats 4. The air intake seats 3 and the interior of the heat dissipation hole 7 are connected through the connecting hole 6.

[0030] During the tapping process, airflow is continuously injected into the heat dissipation hole 7 through the flat end 31. This continuous airflow dissipates heat from the working end 2, thereby continuously reducing its temperature. Simultaneously, since the inlets of the flat ends 31 on the first and second air intake seats 3 and 4 are in opposite directions, both forward and reverse rotation of the shank end 1 can inject airflow into the heat dissipation hole 7 to dissipate heat from the working end 2, achieving continuous heat dissipation. Furthermore, the heat dissipation core 8 and the heat-conducting rod 81 assist and accelerate the heat conduction and dissipation of the working end 2, effectively reducing the temperature of the working end 2 during operation and improving the performance of the tap.

[0031] like Figures 1 to 3 As shown in the figure, in this embodiment, the air intake seat 3 and the air intake seat 4 are the same size. The air intake seat 3 has a flat end 31 on one side and an arc end 33 on the other side. The flat end 31 has an air intake channel 32 that communicates with the connecting hole 6. When the tapping tool 21 taps the workpiece, the heat of the working end 2 and the workpiece will rise rapidly. At this time, the shank end 1 is in a high-speed rotating state. At this time, the airflow in the environment will be poured into the air intake channel 32 and finally enter the heat dissipation hole 7 through the connecting hole 6. The airflow entering the heat dissipation hole 7 will dissipate heat from the working end 2 to reduce the temperature of the working end 2 itself.

[0032] like Figures 1 to 3 As shown in the figure, in this embodiment, the inlet orientation of the air inlet channel 32 on the first air intake seat 3 is opposite to that on the second air intake seat 4. Both forward and reverse rotation of the handle end 1 can inject airflow into the heat dissipation hole 7 to dissipate heat from the working end.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, in this embodiment, a heat dissipation core 8 is fixed at the center of the heat dissipation hole 7. The heat dissipation core 8 is a graphene rod. Multiple sets of heat-conducting rods 81 are fixed on the peripheral surface of the heat dissipation core 8. The end of the heat-conducting rod 81 away from the heat dissipation core 8 abuts against the inner wall surface of the heat dissipation hole 7. The heat-conducting rod 81 is a copper rod. The heat dissipation core 8 is installed inside the heat dissipation hole 7 and is connected to the working end 2 through the heat-conducting rod 81. This helps to quickly absorb and dissipate the heat on the working end 2, thereby improving the heat dissipation rate of the working end 2.

[0034] like Figures 1 to 2 As shown in the figure, in this embodiment, arc-shaped grooves 22 are provided on all four sides of the peripheral surface of the working end 2, and the arc-shaped grooves 22 cut off the tapping tool 21.

[0035] When in use, the drive end of the motor is fixed between the clamping head 5, and the working end 2 can be driven to rotate at high speed by the motor, and the internal thread of the workpiece can be processed by the tapping tool 21.

[0036] When the tapping tool 21 taps the workpiece, the heat of the working end 2 and the workpiece will rise rapidly. At this time, the shank end 1 is in a high-speed rotation state. At this time, the airflow in the environment will be poured into the air inlet channel 32 and finally enter the heat dissipation hole 7 through the connecting hole 6. The airflow entering the heat dissipation hole 7 will dissipate heat on the working end 2 to reduce the temperature of the working end 2 itself.

[0037] A heat dissipation core 8 is installed inside the heat dissipation hole 7 and is connected to the working end 2 through the heat conduction rod 81, which helps to quickly absorb and dissipate the heat on the working end 2.

[0038] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
