Description

Technical Field

[0001] The utility model relates to the field of pipe cutting machines, and more specifically, to a cutting knife for a pipe cutting machine. Background Technique

[0002] The cutting knife of a pipe cutting machine generally refers to a tool or device for cutting pipes or tubes. Such a tool usually needs to have sufficient hardness and wear resistance to ensure effective cutting and severing of the pipe material. Common cutting knives for pipe cutting machines may include stainless steel blades or tools made of special alloys, depending on the type of pipe to be cut and the required cutting quality. In the industrial and manufacturing fields, pipe cutting machines usually come with a variety of different types of tools to handle pipes of different materials and diameters.

[0003] During the cutting process, the cutting knife contacts the surface of the object to be cut and generates frictional force. This frictional effect causes the blade to gradually heat up. If long-term cutting operations are continuously carried out, the temperature of the blade will continue to rise, which will have an adverse impact on the durability and service life of the blade.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cutting knife for a pipe cutting machine in order to solve the above problems.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A cutting knife for a pipe cutting machine includes a blade body. A heat dissipation component is detachably connected to the blade body. A number of heat dissipation fins are fixedly connected to the heat dissipation component. A number of blocks with an L-shaped longitudinal section are fixedly connected to the side of the heat dissipation component facing away from the heat dissipation fins. The number of blocks is evenly distributed in a circumferential array. A number of slots for clamping the ends of the blocks are opened on the blade body.

[0007] The utility model is further arranged as: The block includes a horizontal part and a vertical part. The shape of the opening of the slot is the same as the cross-sectional shape of the horizontal part.

[0008] The utility model is further arranged as: A clamping groove for clamping with the horizontal part is opened on the groove wall of the slot.

[0009] The utility model is further arranged as: A guiding inclined surface is provided on the horizontal part.

[0010] The utility model is further arranged as: The groove wall of the clamping groove is attached to the guiding inclined surface.

[0011] The utility model is further arranged as: A number of grooves are opened on the heat dissipation fins.

[0012] The present utility model is further configured such that: the heat dissipation component is made of aluminum alloy material.

[0013] In summary, the present utility model has the following beneficial effects:

[0014] By providing a heat dissipation component on the blade body, the heat dissipation fins on the heat dissipation component can increase the surface area of the heat dissipation component, improve the efficiency of heat exchange between the heat dissipation component and the air, thereby taking away the heat on the blade body. At the same time, the clamping block on the heat dissipation component is snapped into the clamping groove on the blade body to achieve detachable connection of the heat dissipation component. Thus, after the blade body finishes cutting, the heat dissipation component can take away the heat on the blade body after being installed, and by rotating the heat dissipation component, the end of the clamping block is snapped into the clamping groove, making the heat dissipation component fixed on the blade body.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The cutting knife for a pipe cutting machine, such as Figures 1 to 3As shown in the figure, it includes a blade body 1. A ring-shaped heat dissipation component 2 is detachably connected to the blade body 1. A number of heat dissipation fins 3 are integrally formed on the heat dissipation component 2. Four L-shaped blocks with L-shaped longitudinal sections are integrally formed on the side of the heat dissipation component 2 facing away from the heat dissipation fins 3. The integrally formed heat dissipation fins 3 and blocks are beneficial for the blocks to transfer heat to the heat dissipation fins 3. The four blocks are evenly distributed in a circumferential array. Four clamping grooves 4 for clamping the ends of the blocks are provided on the blade body 1. By providing the heat dissipation component 2 on the blade body 1, the heat dissipation fins 3 on the heat dissipation component 2 can increase the surface area of the heat dissipation component 2 and increase the efficiency of heat exchange between the heat dissipation component 2 and the air, so as to take away the heat on the blade body 1. At the same time, the blocks on the heat dissipation component 2 are inserted into the clamping grooves 4 on the blade body 1 to realize the detachable connection of the heat dissipation component 2. Thus, after the blade body 1 finishes cutting, after installing the heat dissipation component 2, the heat on the blade body 1 can be taken away, and after rotating the heat dissipation component 2, the ends of the blocks are inserted into the clamping grooves 4, so that the heat dissipation component 2 is fixed on the blade body 1. The heat dissipation component 2 is made of aluminum alloy material. Aluminum alloy has good thermal conductivity and strength, which ensures the heat dissipation efficiency of the heat dissipation component 2 and improves the service life of the heat dissipation component 2.

[0022] As Figure 2 and Figure 3 shown in the figure, the block includes a horizontal part 5 and a vertical part 6. The opening of the clamping groove 4 has the same cross-sectional shape as the horizontal part 5, which is beneficial for the block to enter the knife clamping groove 4. A clamping groove 7 for clamping with the horizontal part 5 is provided on the groove wall of the clamping groove 4. Thus, when the horizontal part 5 is clamped into the clamping groove 7, the heat dissipation component 2 can be better fixed on the blade body 1. A guiding inclined surface 8 is provided on the horizontal part 5, which is convenient for the horizontal part 5 to be clamped into the clamping groove 7. The groove wall of the clamping groove 7 fits with the guiding inclined surface 8, which improves the contact surface between the heat dissipation component 2 and the blade body 1 and is beneficial for the heat on the blade body 1 to be transferred to the block and then to the heat dissipation fins 3. When the temperature of the blade is relatively high after cutting, the operator takes out the heat dissipation component 2 and aligns the block with the clamping groove 4. When the block completely enters the clamping groove 4, the operator can rotate the heat dissipation component 2 so that the horizontal part 5 of the block is clamped into the clamping groove 7. Since the guiding inclined surface 8 is provided on the horizontal part 5, the horizontal part 5 can easily enter the clamping groove 7. When the guiding inclined surface 8 of the horizontal part 5 completely fits with the clamping groove 7, the installation of the heat dissipation component 2 on the blade body 1 is completed. A number of grooves 9 are provided on the heat dissipation fins 3, which can further increase the contact area between the heat dissipation fins 3 and the air and further improve the heat dissipation efficiency of the heat dissipation component 2. And in order to cool the blade body 1 faster, the operator can take out a fan and blow air at the heat dissipation fins 3, so that the new cold air contacts the heat dissipation fins 3 and speeds up the cooling speed of the blade body 1.

[0023] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
