Description

Technical Field

[0001] The utility model relates to the technical field of superhard material processing, and particularly relates to a device for shaping cubic boron nitride. Background Technique

[0002] Cubic boron nitride is a new material with high hardness and good wear resistance, and has a wide range of applications in the mechanical processing industry, mainly for the grinding of special steel cutting tools. To ensure the stability of cubic boron nitride during use, it is necessary to shape it to make its particle size more uniform. The existing shaping processes mainly use ball milling equipment such as roller ball mills and vertical wet grinding and stirring ball mills. However, during the processing, due to the high hardness of cubic boron nitride, the impact effect of the roller ball mill is limited by gravity acceleration, resulting in poor crushing effect and slow crushing efficiency. At the same time, due to the above limitations, the crystal form of the crushed cubic boron nitride is relatively single, and it is difficult to process crystal forms with low bulk density and high self-sharpening. For the vertical wet grinding and stirring ball mill, due to the influence of the buoyancy of water, the crushing effect of finer-grained cubic boron nitride is not good, and due to the vertical structure, the crushing force in different depths of the crushing area is different, resulting in poor product consistency.

[0003] The patent with the publication number "CN206152899U" discloses a "cubic boron nitride shaping device", which is the applicant's prior application, including a stirring tank, stirring blades and steel balls. The stirring blades are arranged at the bottom of the stirring tank and are driven by a motor. A large number of steel balls are placed at the bottom of the stirring tank and cover the stirring blades. The stirring blades can rotate horizontally under the drive of the motor, and a single blade can also rotate itself. However, in the solution of this patent, only the materials in one tank can be shaped and stirred at a time, and the stirring method is relatively single, resulting in low shaping efficiency.

[0004] Therefore, this application proposes a device for shaping cubic boron nitride. Summary of the Invention

[0005] The purpose of the utility model is to provide a device for shaping cubic boron nitride, which can shape the materials in multiple tanks at a time, and at the same time diversify the stirring method during the shaping process, greatly improving the shaping efficiency.

Detailed Embodiments

[0021] The present utility model will be further described below with reference to the drawings. Embodiment

[0022] As Figure 1And Figure 2 As shown, a device for cubic boron nitride shaping in this embodiment includes two relatively arranged frames 1. Between the two frames 1, there are two tank body rotating shafts 3. On each tank body rotating shaft 3, there are two tanks 4 for accommodating materials. Inside the tank 4, there is also a stirring part for shaping the materials. On the frame 1, there is a frame rotating shaft 2. During the shaping process, the stirring part drives the materials to do regular circular motion to crush and shape the materials. At the same time, the frame rotating shaft 2 can also drive the frame 1, the tank body rotating shaft 3, and the tank 4 to rotate 360°. The materials do free-fall impact motion inside the tank 4 to crush and shape the materials again, thereby effectively improving the crushing efficiency.

[0023] In some embodiments, multiple tank body rotating shafts 3 such as 3, 4, 5, 6, etc. can also be arranged between the two frames 1. On each tank body rotating shaft 3, multiple tanks 4 such as 3, 4, 5, 6, etc. can be arranged to further increase the quantity of materials shaped at one time and improve the shaping efficiency.

[0024] The tank 4 includes a closed outer shell 41. Inside the tank 4, there is a partition plate 44. The partition plate 44 divides the inside of the tank into a control part and a material part. On the side wall of the outer shell 41, there is a material inlet / outlet 5 for accessing materials. The material inlet / outlet 5 is located on the side of the material part. Through the material inlet / outlet 5, it is convenient to add the materials to be shaped into the tank 4 or take out the shaped materials. Through the setting of the partition plate 44, when the tank 4 rotates with the tank body rotating shaft 3, the materials will not enter the control part and affect the normal operation of the equipment.

[0025] Inside the control part, there is a motor 42. The output shaft of the motor 42 is connected to a stirring rotating shaft 43. The stirring rotating shaft 43 extends into the material part and is connected to the stirring part. On the partition plate 44, there is a bearing for the stirring rotating shaft 43 to pass through. The motor 42 drives the stirring rotating shaft 43 to rotate, and then drives the stirring part to rotate to crush and shape the materials in the material part.

[0026] The stirring part includes a turntable 45 connected to the stirring rotating shaft 43. On the turntable 45, there are two stirring rods 46 for stirring the materials. The turntable 45 rotates to drive the stirring rods 46 to rotate to shape the materials.

[0027] On the surface of the stirring rod 46, there are protrusions 47, which can further improve the efficiency of crushing and shaping.

[0028] Inside the material part, steel balls for stirring the materials are also placed. While improving the crushing efficiency, it can make the rotary crushing process more balanced and improve the consistency of the products.

[0029] When the utility model is in use, first assemble the frame 1 and the frame rotating shaft 2, and then install the tank body 4 on the tank body rotating shaft 3. Open the feeding port 5 to add materials into the tank body 4, and then the stirring part and the frame rotating shaft 2 start to rotate to shape and crush the materials in the tank body 4. After shaping, open the feeding port 5, take out the materials inside and re-add new materials, so as to realize the shaping of the materials.
