Technical Field

[0001] This utility model relates to the field of disc shearing machine technology, and in particular to a lubrication device for disc shearing blade maintenance. Background Technology

[0002] A disc shearing machine uses two disc-shaped shears to cut the sheet metal. Based on the different relative positions (T) of the axes of the two shears and the different angles they make with the sheet metal, the machine is classified into straight disc shears, rotary disc shears, and oblique disc shears.

[0003] However, the blades of the disc shear are prone to wear, and the cutting accuracy and quality cannot be guaranteed. There are long-term problems such as burrs and poor cutting, and blade scratches on the strip surface. In addition, the disc shear blades wear out quickly, resulting in high consumption and high cost. Therefore, the blades need to be replaced frequently, which leads to frequent start-ups and shutdowns. Replacing the disc shear blades is labor-intensive, has high safety risks, and is prone to accidents. Utility Model Content
