Description

Technical Field

[0001] The utility model relates to the technical field of rod pressing devices, in particular to a rod pressing device for producing cubic boron nitride. Background Art

[0002] Cubic boron nitride is a kind of superhard material, and its hardness is second only to diamond. Cubic boron nitride is synthesized by using hexagonal boron nitride and catalyst under high temperature and high pressure. The grinding performance of cubic boron nitride abrasive tools is very excellent. It can not only process difficult-to-grind materials and improve productivity, but also effectively improve the grinding quality of workpieces. In the production of cubic boron nitride tools, cubic boron nitride rods need to be synthesized first.

[0003] For example, the Chinese utility model patent with patent publication number CN220095633U includes a support platform, a rod mold is installed on the support platform, a portal frame is arranged on the upper end of the support platform, a hydraulic telescopic mechanism is vertically arranged on the portal frame, a pressing die is connected to the lower end of the hydraulic telescopic mechanism, a bottom mold is coaxially arranged at the lower end of the rod mold, an iron mounting column is arranged at the lower end of the bottom mold, a limited through hole is horizontally opened on the iron mounting column, limited tubes are arranged on the support platforms on both sides of the iron mounting column, limited shafts are inserted between the limited tubes, and a limited shaft moving mechanism is arranged on the lower end surface.

[0004] Although this patent can use the lowering of the pressing die to eject the cubic boron nitride rods after the rod pressing is completed, which is easy to demold, this patent places the cubic boron nitride rods inside the receiving barrel after being ejected. Since the receiving barrel needs to rotate with it, its own volume cannot be designed to be large, and the receiving barrel will be quickly filled up during production. It is also inconvenient to collect the cubic boron nitride rods inside the receiving barrel, and it is necessary to stop the machine for processing. In view of this, we propose a rod pressing device for cubic boron nitride production. Utility Model Content

After the winding shaft rotates, it cooperates with the second correction wheel and the correction wheel to pull the cable to move.
