Description

Technical Field

[0001] The utility model relates to the technical field of steel rod production, in particular to an oil-cooling rotary die with automatic circulation of lubricating powder. Background Art

[0002] As the market for PC steel bars continues to expand, the varieties and specifications of PC steel bars are becoming more and more abundant. In the processing of PC steel bars, it is necessary to perform rotary notching on the steel bars, that is, to carve multiple spiral grooves on the surface of the steel bars through drawing and dies. Generally, rotary notching is completed by rotary dies.

[0003] For example, Chinese patent CN207615383U discloses a high-pressure active powder loading rotary die box used for steel rod production, which includes a box body, a powder loading area in the box body, and lubricating powder in the powder loading area. The powder loading mechanism includes a base connected to the first partition plate, and the base has a connecting through hole; a conveying screw is arranged in the powder loading area and is rotatably connected to the box body, and one end of the conveying screw extends out of the box body, and the other end is a threaded portion, which is rotatably inserted from one end of the connecting through hole, and at least two threads of one end of the threaded portion are located outside the connecting through hole; a die sleeve is connected to the other end of the connecting through hole, and a powder loading cavity is provided which is connected to the other end of the threaded portion. This high-pressure active powder loading rotary die box changes the passive powder feeding into the active powder feeding. Through the rotation of the conveying screw, the threaded portion brings the lubricating powder in the powder loading area into the powder loading cavity through the connecting through hole. After the lubricating powder is squeezed by the threaded portion, it is attached to the steel rod at high pressure, which greatly improves the lubrication effect.

[0004] Although the above structure can apply lubricating powder to the steel rod, the reuse of the lubricating powder requires the design of a separate circulation structure, and self-circulation is not possible. At the same time, the rotary mold does not involve a cooling structure, and the bearings and notched molds of the rotary mold cannot obtain good heat dissipation, which will aggravate wear.

[0005] Based on this, the utility model designs an oil-cooling rotary die with automatic circulation of lubricating powder to solve the above problems. Utility Model Content
