Technical Field
The utility model relates to a trolley for moving a die on a punch press, in particular to a pressure supply system for hydraulic clamping force of a die clamping device in the trolley of the punch press.
Background
Large presses are typically equipped with a trolley for more efficient and convenient mold replacement. The trolley needs to fix the die through a die clamp, and the clamping of the die by the die clamp generally needs to provide a hydraulic clamping force of about 25MPa for a hydraulic cylinder, so that hydraulic oil can be pumped to the hydraulic cylinder through a pneumatic pump or an electric pump to provide the hydraulic clamping force. However, because the space for installing the pump station in the trolley is very limited, the height is generally below 300mm, the traditional electric pump station cannot meet the requirement of the installation space, and the integrated motor oil tank pump station is very expensive, therefore, the pneumatic pump station is more used in the existing trolley. The pneumatic pump needs to adopt compressed air as a power source when working, and the pneumatic pump needs to be connected with an external air source through an air pipe, but because the trolley needs to move when working, the equipped air pipe is longer, and in order to prevent the air pipe in the trolley from being disordered and even damaged in the moving process, the pneumatic pump can only contain the air pipe through a drag chain, but the cost of the drag chain is higher.
