Shearing machine basic parameters and production guidelines

Determine shear performance include: shearing machine shear, pressing force, shear angle and blade on trips.

1. shearing force determines

Total libiping of oblique edge shear blade shearing machine is small, it consists of three parts: basic shear; cut section under bending of sheet resistance and shear deformation of sheet bending resistance. Always close inverse relationship between shear stress and shear angle, which decreases with the increase of the shear angle.

2. determination of the blank-holder force

In the process of cutting, blades of sheet metal on a forward thrust of t. In order to prevent displacement of the sheet, blank-sheet must be made top and underside of the horizontal friction is greater than the generated on t. Cut beginning, the cutting depth of the blade on reach the moment of cutting thickness, sheet metal top and bottom friction produced is
