Description

Technical Field

[0001] This utility model relates to the field of grinding mechanisms for steel wire shot cutting, and more specifically, to a grinding mechanism for steel wire shot cutting. Background Technology

[0002] Steel wire shot is pellets cut from steel wire. Depending on the type of steel wire used, it is divided into stainless steel steel wire shot, ordinary high-carbon steel wire shot, and low-carbon steel wire shot. The pellets can be unpassivated (cylindrical) or passivated (round).

[0003] In the process of steel wire shot cutting, the steel wire is cut into small segments and then ground in a grinding device to round off the protruding corners to finally form a sphere. The existing grinding device produces a lot of debris and powder that falls together with the shot during the grinding process, which requires screening later, causing great inconvenience to the grinding process.

[0004] In the prior art, such as the authorized announcement number CN215940559U, this utility model belongs to the field of steel wire shot processing technology, and in particular, a steel wire shot grinding device. It addresses the problem that during grinding, the shot and residual powder fall together, causing inconvenience in subsequent processing and easy clogging during feeding. The proposed solution includes a steel wire shot grinding box, which also includes a feeding hopper. The feeding hopper is fixed to the top side wall of the steel wire shot grinding box and is connected to the inside of the box. Two symmetrically distributed drive shafts are rotatably connected to the inner side wall of the grinding box. Grinding rollers are tightly fitted onto the outer surface of both drive shafts. A spur gear a is provided at the same end of both drive shafts, and the two spur gears a mesh with each other. In this utility model, the intermittent operation of the rotating shaft c drives the tilting plate to rotate synchronously, intermittently tilting the steel wire shot. Combined with the partition plate, the steel wire shot is concentrated and falls to the grinding rollers, preventing clogging of the feeding hopper and avoiding affecting subsequent processing steps.

[0005] In the aforementioned patent, a motor is used in conjunction with a transmission belt to rotate the grinding roller, and the bottom screening mechanism uses an independent motor for extrusion and vibration screening. This results in high driving costs, multiple driving devices, inconvenient installation and transmission of the driving motor, and inconvenient discharge of the steel shot remaining on the surface.
