Description

Technical Field

[0001] The utility model belongs to the technical field of cubic boron nitride synthesis, and particularly relates to a cubic boron nitride synthesis device. Background Art

[0002] Cubic boron nitride (CBN) is a new synthetic material first discovered in the 1950s. Its extremely high hardness and wear resistance have led to its widespread use in the machining industry. Its hardness is even comparable to that of diamond, making it often used as an abrasive and cutting tool. CBN's atomic structure is similar to that of carbon atoms in diamond, resulting in its high density. These properties make CBN a highly unique material with potential applications beyond machining. For example, due to its excellent thermal conductivity and lubricity, CBN is also used in the electronics and energy industries. The conventional process for synthesizing CBN involves mixing CBN and a catalyst in appropriate proportions, pressing the mixture into a rod-like shape, loading it into a graphite heating tube, placing heating plates at both ends, then inserting it into a pyrophyllite synthesis chamber, securing conductive plugs at both ends, and subjecting it to high-temperature, high-pressure growth conditions on a six-sided press. Currently available cubic boron nitride synthesis devices cannot rotate cubic boron nitride during the synthesis process. Therefore, a synthesis device that can rotate cubic boron nitride during the synthesis process is needed to improve the growth conditions of cubic boron nitride and achieve better growth quality. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a cubic boron nitride synthesis device, which solves the problems in the above-mentioned background technology.

[0004] The purpose of the present utility model is achieved as follows: a cubic boron nitride synthesis device, comprising a synthesis chamber, wherein a first transverse plate and a second transverse plate are fixedly installed inside the synthesis chamber, a heat insulation layer is installed on the inner wall of the synthesis chamber and above the first transverse plate, a first heating layer is installed inside the heat insulation layer, a top cover is detachably fixed on the top of the synthesis chamber, and a second heating layer is installed on the inner wall of the top cover; a bearing assembly is installed above the first transverse plate, and a driving assembly connected to the bearing assembly is installed above the second transverse plate; a side opening is opened on the side wall of the synthesis chamber, and a side door is provided on the side opening. When in use, the side door of the synthesis chamber is opened, and the cubic boron nitride is placed above the bearing assembly through the side opening. During the growth process of the cubic boron nitride, the bearing assembly is used to drive the cubic boron nitride to rotate, so that the cubic boron nitride grows in the process of slow rotation, greatly improving its growth quality.

[0005] Furthermore, the support assembly includes a support plate positioned above the first transverse plate. A vertical shaft is fixedly connected to the center of the support plate's lower surface. The vertical shaft extends through the first transverse plate and extends below the first transverse plate, rotating in conjunction with the first transverse plate. A stabilizing assembly is positioned above the first transverse plate and connected to the support plate. During operation, the drive assembly rotates the vertical shaft, which in turn rotates the support plate, which in turn rotates the cubic boron nitride (CBN) placed above the support plate. The stabilizing assembly ensures a more stable and smooth rotation of the CBN driven by the support plate.

[0006] Furthermore, the stabilizing assembly includes an annular groove formed on the upper surface of the first transverse plate, and a first vertical pin and a second vertical pin are fixedly connected to the lower surface of the carrier plate. The first vertical pin and the second vertical pin are symmetrically arranged with each other, and the lower ends of the first vertical pin and the second vertical pin are slidably connected within the annular groove. During use, when the carrier plate rotates, the first and second vertical pins move synchronously. Due to the provision of the annular groove, the movement trajectories of the first and second vertical pins are restricted, thereby limiting the movement of the carrier plate in the opposite direction through the first and second vertical pins.

[0007] Furthermore, the drive assembly includes a motor fixedly mounted on the upper surface of the second horizontal plate, with the motor's output shaft extending upward and connected to a reduction gearbox. The reduction gearbox's output shaft is connected to the lower end of the vertical shaft. During use, the motor drives the reduction gearbox and the vertical shaft to rotate, thereby driving the carrier plate and the cubic boron nitride to rotate.

[0008] Furthermore, the synthesis chamber is in the shape of a hexagonal prism, and a foot pad is provided at the lower end of the synthesis chamber; the top view of the support plate is circular, and the first vertical pin, the second vertical pin and the support plate are integrally formed; the motor is electrically connected to an electronic control device, and the electronic control device is electrically connected to the first heating layer, and the electronic control device is electrically connected to the second heating layer.

[0009] The beneficial effects of the present invention are as follows: through the setting of the stabilizing component, the process of the support plate driving the cubic boron nitride to rotate is more stable and smooth. When in use, the side door of the synthesis chamber is opened, and the cubic boron nitride is placed on top of the support component through the side port. During the growth of the cubic boron nitride, the support component is used to drive the cubic boron nitride to rotate, so that the cubic boron nitride grows in the process of slow rotation, which greatly improves its growth quality. The driving component drives the vertical axis to rotate, and the vertical axis drives the support plate to rotate, thereby driving the cubic boron nitride placed on the support plate to rotate. When the support plate rotates, it drives the first vertical pin and the second vertical pin to move synchronously. Due to the setting of the annular groove, the movement trajectory of the first vertical pin and the second vertical pin is restricted, so the movement of the support plate is then restricted in the reverse direction by the first vertical pin and the second vertical pin.
