Description

Technical Field

[0001] The utility model relates to a cutting roller, in particular to a main cutting roller with a water cooling structure. Background Art

[0002] In the photovoltaic industry, diamond wire multi-wire cutting machines are used, and the main cutting rollers of diamond wire multi-wire cutting are installed in pairs on the multi-wire cutting machine for cutting and processing silicon wafers.

[0003] Currently, the structure of the main roller on the market is that the end caps at both ends are welded to the cylinder body. The cylinder body is made of all metal, with a large weight. When the rotation speed is high during use and the use time increases, the cylinder body is prone to deformation, and the concentric accuracy of the conical surface and the outer circle will be weakened, thus affecting the service life of the main roller. The large weight makes the disassembly and installation time-consuming and laborious, increasing the production cost and greatly reducing the practicability of the device. When the cutting roller operates for a long time, the metal wheel body generates heat, resulting in a decrease in accuracy and a shortening of the service life. Summary of the Utility Model

[0004] The utility model provides a main cutting roller with a water cooling structure to overcome the defects that when the cutting roller operates for a long time, the metal wheel body generates heat, resulting in a decrease in accuracy and a shortening of the service life in the prior art.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a main cutting roller with a water cooling structure, which includes a cooling roller. Axle heads are respectively and cooperatively installed at both ends of the cooling roller. The cooling roller is assembled in a tube. Both ends of the tube are respectively cooperated with end caps. A spiral inner cavity for water cooling is arranged on the cooling roller.

[0007] Furthermore, the connection parts between both sides of the tube and the end caps are strengthened by groove welding.

[0008] Furthermore, the cooling roller and the tube are assembled by interference fit.

[0009] Furthermore, both ends of the tube and the end caps are in interference fit.

[0010] The beneficial effects achieved by the utility model are as follows: The cooling roller is provided with a spiral groove water path, which can stabilize the temperature of the workpiece, thereby prolonging its service life, facilitating disassembly and installation, having high repeat positioning accuracy, strong consistency, light weight, good mechanical properties, being applicable to high rotation speeds, greatly improving production efficiency, and reducing manufacturing costs.
