Description

Technical Field

[0001] The utility model relates to the field of cubic boron nitride production equipment, in particular to a binder adding device for PCBN material production. Background Art

[0002] PCBN material, also known as cubic boron nitride material, is a synthetic superhard material, often used to make knives. Knives made of cubic boron nitride material have high hardness, high wear resistance and high thermal stability. In the production of PCBN material, PCBN powder and binder are fully mixed and then synthesized in a high temperature and high pressure environment. Binders can be divided into metal binders and ceramic binders according to their components. The uniformity of mixing PCBN powder and binder affects the performance of PCBN material. In order to improve the uniformity of mixing, you can choose to use the method of slowly and evenly adding raw materials during mixing to achieve slow and even feeding of materials. The existing practice is often manual feeding, which not only has low precision but also occupies labor for a long time. Therefore, it is particularly necessary to develop a binder adding equipment for PCBN material production that can independently and evenly feed. Summary of the invention

[0010] Compared with the prior art, the beneficial effects are:

[0011] 1. The utility model utilizes a vibration motor to drive the vibration of a metal rod to loosen the adhesive and flow it into a discharge pipe, and utilizes a material trough on a discharge roller to sequentially transfer the adhesive to the bottom of the discharge roller, thereby realizing the gradual and uniform addition of the adhesive.

[0012] 2. The rotating pushing screw in the utility model pushes the adhesive in the tank body to gather toward the discharge pipe.
