Description

Technical Field

[0001] This utility model relates to tool holder cooling, specifically a tool holder cooling device. Background Technology

[0002] The original shearing blades on the equipment would heat up after rapid cutting, and the heat would gradually transfer to the blade holder, eventually causing the temperature of both the blade and the blade holder to rise. The metal blades would heat up and expand, narrowing the gap between them. This narrowing gap would exacerbate the heating, making the blades more prone to damage and resulting in high mechanical stress.

[0003] The moving blade holder reciprocates at high speed in the horizontal direction, and the moving blade and the fixed blade perform a shearing action. A small gap of 0.05-0.08mm is maintained between the fixed and moving blades during installation to prevent friction or collision between them. During operation, the equipment generates heat. The thermal expansion and contraction properties of metal cause the fixed blade holder, fixed blade, moving blade holder, and moving blade to expand. Therefore, the gap between the fixed and moving blades gradually decreases, potentially leading to friction or collision and damage to the blades and the equipment.

[0004] The current method involves creating a U-shaped flow channel, where two long holes are connected at one end to allow cooling water to circulate, but this reduces the strength of the tool holder. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a tool holder cooling device. This utility model only requires one hole to achieve cooling without affecting the strength of the tool holder. It is easy to install and has low cost.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a tool holder cooling device, comprising a fixed tool holder and a movable tool holder, both the fixed tool holder and the movable tool holder being provided with elongated blind holes, a self-circulating cooling component being provided within the elongated blind holes, the self-circulating cooling component comprising a short outer tube and a long inner tube, the short outer tube being installed at the opening of the elongated blind hole, the long inner tube being placed inside the short outer tube, the gap between the short outer tube and the long inner tube being used for water inlet cooling, and the long inner tube being used for reflux.

[0007] The inner end of the long inner tube extends into the depth of the long blind hole, and the inner end of the long inner tube is provided with a suction port.

[0008] The short outer tube has an opening in its end wall and a support ring is fixed thereon. The outer end of the long inner tube passes through the support ring and extends to the outside.

[0009] One part of the short outer tube is placed inside the long blind hole, and the other part is placed outside the long blind hole, with a connecting tube provided on the peripheral wall of the part placed outside.

[0010] A connecting pipe is fixed to the outer periphery of the short outer tube. The connecting pipe is a hollow T-shaped tube, and a portion of the connecting pipe is threaded into the long blind hole.

[0011] The short outer tube is equipped with an auxiliary support for supporting the long inner tube.

[0012] The auxiliary support includes an outer ring, an inner ring, and a connecting rod. The outer ring is threaded to the inner end of the short outer tube. The inner ring is coaxial with the outer ring. One end of the connecting rod is fixedly connected to the outer ring, and the other end is fixedly connected to the inner ring. The long inner tube passes through the inner ring.

[0013] In summary, this utility model achieves the following technical effects: This invention adds a heat dissipation device to the tool holder, keeping the tool holder at a relatively low temperature. The blade and the tool holder are in contact, and the heat generated by the blade is offset through heat transfer between them, so that the temperature of the blade does not become too high.

[0014] This invention reduces the temperature of the machine's operating parts, minimizes mechanical damage, and provides support for increasing the cutting speed.

[0015] This invention adds circulation pipes at the fixed tool holder and the moving tool holder locations. These pipes are connected to cooling water, which continuously circulates and removes heat, thus controlling the temperature of the fixed and moving tool holders. The large contact area between the blades and the tool holder, along with heat conduction between the metals, prevents the fixed and moving blades from overheating. The stable temperature ensures that the pre-set blade gap remains constant, preventing friction or collision between the blades even during prolonged high-speed operation.

[0023] Example: Figure 1 A tool holder cooling device includes a fixed tool holder 1 and a movable tool holder 2. Both the fixed tool holder 1 and the movable tool holder 2 are provided with long blind holes. A self-circulating cooling component 3 is provided in the long blind holes. The self-circulating cooling component 3 includes a short outer tube 32 and a long inner tube 33. The short outer tube 32 is installed at the opening of the long blind hole, and the long inner tube 33 is placed inside the short outer tube 32. The gap between the short outer tube 32 and the long inner tube 33 is used for water inlet cooling, and the long inner tube 33 is used for reflux.

[0024] This invention features a self-circulating water cooling device that can remove heat from the moving and stationary tool holders. Because it is self-circulating, only a long blind hole is needed, which avoids compromising the stability of the tool holder and makes installation convenient.

[0025] Figure 2 This is a schematic diagram of the fixed tool holder. The self-circulating installation method of the moving tool holder 2 is the same as that of the fixed tool holder. This embodiment takes the fixed tool holder as an example. Figure 3 yes Figure 2 The enlarged schematic diagram of part A in this embodiment shows that the long blind hole is labeled 101, indicating the long blind hole of the fixed tool holder.

[0026] A portion of the short outer tube 32 is placed inside the long blind hole, and another portion is placed outside the long blind hole, with a connector tube 321 provided on the peripheral wall of the portion placed outside.

[0027] Specifically, a connecting pipe 31 is fixed to the outer periphery of the short outer tube 32. The connecting pipe 31 is a hollow T-shaped tube, and a portion of the connecting pipe 31 is threaded into the long blind hole.

[0028] This invention features a shorter outer tube structure, which serves as a water inlet pipe, allowing cooling water to be introduced into a long blind hole. The outer tube is secured using a connecting pipe 31, and multiple sealing rings 4 are used to achieve a sealing effect.

[0029] The end wall of the short outer tube 32 is perforated and a support ring 322 is fixed thereon. The outer end of the long inner tube 33 passes through the support ring 322 and extends to the outside.

[0030] The support ring in this invention can enhance the supporting effect.

[0031] The short outer tube 32 is provided with an auxiliary support member 34 for supporting the long inner tube 33.

[0032] Figure 4This is a cross-sectional schematic diagram of the auxiliary support component 34, which includes an outer ring 341, an inner ring 343, and a connecting rod 342. The outer ring 341 is threaded to the inner end of the short outer tube 32. The inner ring 343 is coaxial with the outer ring 341. One end of the connecting rod 342 is fixedly connected to the outer ring 341, and the other end is fixedly connected to the inner ring 343. The long inner tube 33 passes through the inner ring 343.

[0033] The gap 344 formed by this utility model allows water to enter and guide cooling water into the long blind hole. The threaded connection between the outer ring and the outer tube facilitates installation.

[0034] Figure 5 yes Figure 2 The enlarged schematic diagram of part B shows that the inner end of the long inner tube 33 extends to the depth of the long blind hole, and the inner end of the long inner tube 33 is provided with a suction port 331.

[0035] This invention utilizes an outer pipe to introduce cooling water. Once the cooling water flows deep into the long blind hole, it carries away the heat from the tool holder, thus cooling the tool holder. After the water becomes hot, it is drawn back into the inner pipe through the return suction port and flows out, achieving self-circulating cooling.

[0036] Both the inner and outer pipes are equipped with water pipes that connect to the water pump and water tank.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
