Description

Technical Field

[0001] This invention relates to a special equipment for steel strip production, and more particularly to a special equipment for CNC steel strip mirror polishing. Background Technology

[0002] Steel belts are a high-quality material for conveyor belts. Their strength yet flexibility allows them to be used in various industrial production processes. Their smooth surface allows them to come into contact with a wide variety of materials, making them highly effective for different processing operations and resulting in a wide range of applications. Steel belts are resistant to both high and low temperatures, suitable for environments ranging from -50°C to 250°C. They can transport high-temperature items that rubber and resin conveyor belts cannot handle, and can also perform heating operations for baking, roasting, steaming, and boiling food. Furthermore, they can be cleaned using high-temperature steam. They can also be used in cold storage, as steel belts will not deform even at low temperatures, making them suitable for continuous freezing operations of food in cold storage.

[0003] Steel strips can develop roughness, scratches, and other defects during use, so they generally need repair every 3-6 months. The main equipment for repair is grinding and polishing the steel strip. Currently, most polishing equipment on the market uses wood polishing machines instead. Wood polishing machines use abrasive belts, consume a lot of power (around 100kW normally), have high abrasive belt consumption, generate high noise during polishing, and produce pollution from the use of coolant. Summary of the Invention

[0004] To address the aforementioned issues, this invention discloses a special CNC steel strip mirror polishing equipment. Depending on the processing objective, it can employ different mesh sizes of abrasive belts (or grinding wheels) for grinding and mirror polishing, featuring low power consumption, environmental friendliness, high production efficiency, simple operation, and environmental friendliness.

[0005] A CNC steel strip mirror polishing equipment includes an integral machine base, an annular steel strip drive wheel, a steel strip tensioning wheel, an annular steel strip drive mechanism, and a CNC steel strip guide; a steel strip grinding head, a grinding head floating mechanism, a grinding head lifting mechanism, a steel strip support roller mechanism, a steel strip support roller lifting mechanism, a pneumatic system, and a CNC electrical controller; the annular steel strip drive mechanism and the grinding head lifting mechanism are both fixed on the integral machine base; one end of the annular steel strip drive mechanism is connected to the annular steel strip drive wheel, and the other end is connected to the steel strip tensioning wheel; both ends of the steel strip are connected to the annular steel strip drive wheel and the steel strip tensioning wheel, respectively; a steel strip support roller mechanism is provided below the steel strip and in close contact with it; the bottom of the steel strip support roller mechanism is connected to the steel strip support roller lifting mechanism; wherein the steel strip grinding head is fixed on the grinding head floating mechanism.

[0006] Furthermore, the grinding head floating mechanism is mounted on the workpiece clamping mechanism.

[0007] Furthermore, the workpiece clamping mechanism is mounted on the workpiece rotating mechanism.

[0008] Furthermore, a feeding mechanism is provided along the width direction of the workpiece; the end of the feeding mechanism is connected to a workpiece clamping mechanism.

Place both ends of the steel belt onto the annular steel belt drive wheel and the steel belt tensioning wheel respectively, and tension the steel belt with the tensioning wheel; adjust the steel belt support roller lifting mechanism so that the steel belt support roller mechanism is close to the bottom of the steel belt.

[0012] 2. The annular steel belt drive mechanism drives the steel belt to rotate, which in turn rotates the grinding wheel, grinding head, and grinding head floating mechanism. The workpiece rotation mechanism then polishes the longitudinal joints of the inner and outer surfaces of the steel belt.

[0013] 3. The feeding mechanism along the width of the workpiece works, the grinding wheel and grinding head and the grinding head floating mechanism work, and the inner and outer sides of the steel belt are polished laterally.
