[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution:

[0026] A high-efficiency cooling cemented carbide forming tool includes a mounting rod 1, a splined rod 2 fixedly connected to the lower end of the mounting rod 1, and a forming tool body 3 detachably connected to the outside of the splined rod 2; the mounting rod 1 has a pre-reserved groove 4 with an annular structure in the middle, and two symmetrically distributed guide rails 5 fixedly connected to the middle of the inner side of the pre-reserved groove 4; a guide tube 6 is provided inside the mounting rod 1, the upper end of the guide tube 6 is connected to the two guide rails 5, and the end of the guide tube 6 away from the guide rails 5 is connected to the lower end of the mounting rod 1.

[0027] The reserved slot 4 is rotatably connected to a rotating sleeve 7. The rotating sleeve 7 is fitted on the outside of the two guide rails 5 to form a rotating sealing structure. The top and bottom of the rotating sleeve 7 are provided with first mounting slots 8.

[0028] The inner top and bottom of the reserved groove 4 are provided with a second mounting groove 9, which corresponds to the first mounting groove 8 one by one. A ball bearing assembly is installed between the first mounting groove 8 and the second mounting groove 9.

[0029] The ball assembly includes balls 10 rotatably connected between a first mounting groove 8 and a second mounting groove 9. The balls 10 are equidistantly distributed between the first mounting groove 8 and the second mounting groove 9, and a retainer 11 is sleeved on the outer side of the balls 10.

[0030] A connector 15 is fixedly connected to one side of the rotating sleeve 7. The connector 15 is connected to the refrigerant supply equipment. A sealed space is formed inside the rotating sleeve 7 and is connected to the conduit 6. The end of the conduit 6 away from the rotating sleeve 7 is opposite to the cutting area of ​​the forming blade body 3.

[0031] When using this highly efficient cooled carbide forming tool, firstly, the forming tool body 3 is assembled on the outside of the spline rod 2 at the lower end of the mounting rod 1 via a detachable connection. After the initial assembly of the tool is completed, the mounting rod 1 is connected and fixed to the actuator of the corresponding machine tool to ensure that the tool as a whole has a stable mounting base during the machining process.

[0032] When the machine tool is started and the cutting tool is driven to perform cutting operations, the forming tool body 3 will move together with the mounting rod 1 according to the preset machining trajectory, contact the workpiece to be processed and complete the forming cutting. During this process, the cutting area of ​​the forming tool body 3 will generate a lot of heat due to friction, which needs to be cooled down through the cooling system.

[0033] When the cooling system is in operation, the connector 15 fixedly connected to one side of the rotating sleeve 7 is first connected to the external coolant supply equipment. The coolant enters the sealed space formed inside the rotating sleeve 7 through the connector 15. Since the rotating sleeve 7 is fitted on the outside of the two guide rails 5 in the middle of the inner side of the reserved groove 4 and forms a rotating sealing structure, the second mounting grooves 9 at the top and bottom of the inner side of the reserved groove 4 correspond one-to-one with the first mounting grooves 8 at the top and bottom of the rotating sleeve 7. In the ball assembly installed between the two, the balls 10 are evenly distributed under the constraint of the cage 11. When the mounting rod 1 rotates with the machine tool spindle, the rotating sleeve 7 can rotate stably around the guide rail 5 relative to the mounting rod 1, effectively preventing the external coolant supply pipeline from getting tangled or damaged due to the rotation of the mounting rod 1.

[0034] Subsequently, the coolant in the sealed space of the rotating sleeve 7 enters the conduit 6 inside the mounting rod 1 through the channel between the two guide rails 5, and flows downward along the extension path of the conduit 6. Since the end of the conduit 6 away from the rotating sleeve 7 is opposite to the cutting area of ​​the forming tool body 3, the coolant can be accurately delivered to the cutting part where the forming tool body 3 contacts the workpiece, promptly removing the heat generated during the cutting process, and at the same time providing a certain lubrication to the cutting area. Meanwhile, the balls 10 in the ball assembly can convert the sliding friction between the rotating sleeve 7 and the mounting rod 1 into rolling friction when the rotating sleeve 7 and the mounting rod 1 rotate relative to each other, reducing the relative motion resistance and ensuring smooth rotation of the rotating sleeve 7. At the same time, in conjunction with the rotary sealing structure, it effectively prevents the coolant from leaking from the gap between the rotating sleeve 7 and the guide rail 5 during flow and equipment operation, ensuring the stable operation of the cooling system.

[0035] Example 2: Based on Example 1, please refer to... Figure 2 The following structure was also disclosed:

[0036] A fixing hole 12 is provided in the middle of the bottom outer side of the spline rod 2, and a fixing bolt 13 is threaded inside the fixing hole 12; a mounting hole 14 is provided in the middle of the forming blade body 3, and the forming blade body 3 cooperates with the spline rod 2 through the mounting hole 14, and the fixing bolt 13 is installed inside the fixing hole 12 to fix the forming blade body 3.

[0037] When assembling the forming cutter body 3, the forming cutter body 3 is first installed with the spline rod 2 through the mounting hole 14 in the middle. Utilizing the structural characteristics of the spline connection, the forming cutter body 3 can be circumferentially positioned, preventing the forming cutter body 3 from rotating circumferentially relative to the spline rod 2 during subsequent cutting operations, thus providing a basic guarantee for machining accuracy. After the forming cutter body 3 is adjusted to the preset installation position on the spline rod 2, the fixing bolt 13 is screwed into one end of the fixing hole 12 in the middle of the bottom outer side of the spline rod 2. Through the threaded engagement between the fixing bolt 13 and the fixing hole 12, the end of the fixing bolt 13 can be pressed against the end face of the forming cutter body 3, thereby forming an axial limit for the forming cutter body 3.
