Technical Field

[0001] This utility model relates to the field of wood cutting tool technology, and more specifically, to a wood cutting tool with a cooling mechanism. Background Technology

[0002] Wood cutting is a core process in woodworking and wood product manufacturing. Traditional wood cutting tools often suffer from excessively high tool temperatures due to frictional heat during high-speed cutting. High-temperature environments not only accelerate the wear of tool materials, reduce the sharpness and cutting accuracy of the blade, but may also cause the wood surface to burn. Therefore, it is necessary to use wood cutting tool heads with cooling mechanisms.

[0003] A search revealed a prior art end mill with an internal cooling structure, patent publication number CN222020729U. The specification states that a connecting ring is threaded between the cutter holder and the cutter head, significantly improving the stability of the tool during cutting. Furthermore, the cooperation between the cutter holder fixing groove, the cutter head fixing groove, and the fixing bolt greatly enhances overall stability, effectively preventing the cutter holder and cutter head from loosening during cutting and preventing them from falling off.

[0004] However, in actual use, although the above-mentioned cutting milling cutter can effectively prevent the tool holder from loosening when cutting, after a long period of use, due to its relatively fixed structure, it is impossible to disassemble and install it separately when replacing or maintaining the drain pipe, so the entire tool holder needs to be replaced, which increases maintenance costs and affects the performance of the cutting head. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wood cutting head with a cooling mechanism to solve the problem that in the prior art, when replacing or maintaining the drain pipe, it is impossible to disassemble and install it separately, so the entire handle needs to be replaced, which increases maintenance costs and affects the performance of the cutting head.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a wood cutting blade with a cooling mechanism, comprising a blade body, wherein an installation groove is provided inside the blade body, a fixing pipe is fixedly connected to the left side of the inner wall of the installation groove, an installation pipe is threadedly connected to the right side of the inner wall of the installation groove, an input pipe is inserted into the middle of the installation pipe, a support ring is installed at the left end of the installation pipe, and a filter plate is installed on the inner ring wall of the support ring.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: a wood cutting blade with a cooling mechanism, including a blade body 1. The blade body 1 has an internal mounting groove 16. A fixing pipe 3 is fixedly connected to the left side of the inner wall of the mounting groove 16, and an mounting pipe 4 is threadedly connected to the right side of the inner wall of the mounting groove 16. An input pipe 2 is inserted into the middle of the mounting pipe 4. A support ring 7 is installed at the left end of the mounting pipe 4. A filter plate 14 is installed on the inner ring wall of the support ring 7. The left end of the input pipe 2 is in contact with the filter plate 14, thereby filtering impurities in the coolant and reducing the risk of blockage in the delivery channel. The left side of the support ring 7 is in contact with the right end of the fixing pipe 3, and the outer ring wall of the support ring 7 is in contact with the mounting groove 16, thereby increasing the sealing between the fixing pipe 3 and the mounting pipe 4 using the support ring 7 and reducing the risk of coolant leakage.

[0027] In use, first pull the input pipe 2 to the right to remove it separately. At the same time, screw the outer right side of the mounting pipe 4 to the right side of the inner wall of the mounting groove 16 and gradually detach it. This makes it easier to pull the mounting pipe 4 to the right for replacement. After that, reset the mounting pipe 4 and the input pipe 2 to complete the assembly. At the same time, the filter plate 14 is used to reduce the amount of impurities in the coolant that are guided into the input channel through the fixed pipe 3, preventing blockage and improving the performance of the cutter head body 1.

[0028] Example 2: Based on Example 1, in order to facilitate the disassembly of the input tube 2 and the separate replacement of the mounting tube 4, a connector 5 is installed at the right end of the mounting tube 4, and a mounting bolt 6 is installed on the outer right side of the input tube 2. The mounting bolt 6 is threaded onto the outer right side of the connector 5, so that the mounting bolt 6 can be unscrewed to remove the input tube 2 separately. The left side of the connector 5 fits against the right side of the cutter head body 1, thereby increasing the installation seal between the mounting tube 4 and the cutter head body 1.

[0029] In use, first rotate the mounting bolt 6 to disengage it from the right outer side of the connector 5, making it easier to pull the input tube 2 to the right for individual removal. Simultaneously, rotate the connector 5 to screw the right outer side of the mounting tube 4 onto the right side of the inner wall of the mounting groove 16, and gradually disengage it, making it easier to pull the mounting tube 4 out to the right for replacement. After completion, reset the mounting tube 4 and bring the left side of the connector 5 into contact with the right side of the cutter head body 1. At the same time, reset the input tube 2 and screw the mounting bolt 6 onto the right outer side of the connector 5 to complete the assembly. This modular design allows for the individual replacement of a single part, reducing replacement costs.

[0030] Example 3: Based on Example 2, to facilitate subsequent maintenance of the filter plate 14, a insertion groove 15 is provided at the left end of the mounting pipe 4, and fastening grooves 13 are provided on both the upper and lower sides of the left side of the support ring 7. Positioning rods 12 are installed on both the front and rear sides of the left side of the support ring 7. A rubber insert ring 10 is installed on the right side of the support ring 7. An inner rubber protrusion ring 9 is installed on the inner ring wall of the rubber insert ring 10, and an outer rubber protrusion ring 11 is installed on the outer ring wall. Two positioning grooves 8 are provided at the right end of the fixing pipe 3. The positioning rods 12 are inserted into the inner wall of the positioning grooves 8, thereby facilitating the positioning and installation of the support ring 7. The rubber insert ring 10 is inserted into the inner wall of the insertion groove 15, the outer rubber protrusion ring 11 is installed on the outer ring wall of the insertion groove 15, and the inner rubber protrusion ring 9 is installed on the inner ring wall of the insertion groove 15. By utilizing the cooperation between the outer rubber protrusion ring 11 and the inner rubber protrusion ring 9, the friction between the rubber insert ring 10 and the insertion groove 15 is increased, thereby increasing the firmness of the installation between the support ring 7 and the mounting pipe 4 and facilitating subsequent maintenance and use.

[0031] When maintenance of filter plate 14 is required, first remove the inlet pipe 2 and the mounting pipe 4 from the mounting groove 16. At this time, the two positioning rods 12 on the left side of the support ring 7 will disengage from the positioning groove 8. After the support ring 7 disengages from the inner wall of the mounting groove 16, it will engage the upper and lower locking grooves 13 and pull the support ring 7 to the left, thereby causing the rubber insert ring 10 to disengage from the insertion groove 15, and simultaneously causing the outer rubber protrusion ring 11 and the inner rubber protrusion ring 9 to disengage from the insertion groove 15. Then, the filter plate 14 can be maintained. After maintenance, reset it and... The movable rubber insert ring 10 is inserted into the inner wall of the insertion groove 15, while the outer rubber protrusion ring 11 and the inner rubber protrusion ring 9 are pushed into the inner wall of the insertion groove 15 and deformed by compression, so as to increase the friction between the rubber insert ring 10 and the insertion groove 15, thereby improving the stability of the installation between the support ring 7 and the left end of the mounting tube 4 and facilitating subsequent maintenance and use. Then the mounting tube 4 and the input tube 2 can be reset respectively, and the positioning rod 12 is driven to insert into the inner wall of the positioning groove 8, thereby improving the use effect of the cutter head body 1.

[0032] The working process of this utility model is as follows:

[0033] In use, first rotate the mounting bolt 6 to disengage it from the right outer side of the connector 5, making it easier to pull the input pipe 2 to the right for individual removal. At the same time, rotate the connector 5 to screw the right outer side of the mounting pipe 4 to the right side of the inner wall of the mounting groove 16, and gradually disengage it, making it easier to pull the mounting pipe 4 to the right for replacement. After completion, reset the mounting pipe 4 and bring the left side of the connector 5 into contact with the right side of the cutter head body 1. At the same time, reset the input pipe 2 and screw the mounting bolt 6 to the right outer side of the connector 5 to complete the assembly. The modular design allows for individual replacement of parts, reducing replacement costs. The filter plate 14 reduces impurities in the coolant from being guided into the input channel through the fixed pipe 3, preventing blockage and improving the performance of the cutter head body 1.

[0034] When maintenance of filter plate 14 is required, first remove the inlet pipe 2 and the mounting pipe 4 from the mounting groove 16. At this time, the two positioning rods 12 on the left side of the support ring 7 will disengage from the positioning groove 8. After the support ring 7 disengages from the inner wall of the mounting groove 16, it will engage the upper and lower locking grooves 13 and pull the support ring 7 to the left, thereby causing the rubber insert ring 10 to disengage from the insertion groove 15, and simultaneously causing the outer rubber protrusion ring 11 and the inner rubber protrusion ring 9 to disengage from the insertion groove 15. Then, the filter plate 14 can be maintained. After maintenance, reset it and... The movable rubber insert ring 10 is inserted into the inner wall of the insertion groove 15, while the outer rubber protrusion ring 11 and the inner rubber protrusion ring 9 are pushed into the inner wall of the insertion groove 15 and deformed by compression, so as to increase the friction between the rubber insert ring 10 and the insertion groove 15, thereby improving the stability of the installation between the support ring 7 and the left end of the mounting tube 4 and facilitating subsequent maintenance and use. Then the mounting tube 4 and the input tube 2 can be reset respectively, and the positioning rod 12 is driven to insert into the inner wall of the positioning groove 8, thereby improving the use effect of the cutter head body 1.
