Shearing machine |
摘要 |
A shearing machine is so arranged that the ram, when vertically moved, is resiliently guided by spring guides and is driven in such a manner as to be kept urged into contact with the guides. The shearing machine is provided with hold-down clamps which can firmly hold the work-sheet being sheared without damaging the work-sheet. A hydraulic pump for the the hold-down clamps is provided with a large diameter piston which will supply a large amount of flow under low pressure and damp the surge and a small diameter piston which will supply a small amount of flow under high pressure. The shearing machine is also provided with hold-up supports which will hold up the work-sheet being sheared to prevent the work-sheet from bending and curling. The shearing machine also has with a back gauge which can be used to set the widths or lengths into which the work-sheet is to be sheared but can be moved out of the way.
