Abstract
The invention relates to an electrohydraulic pressing device (1) that can be operated using one hand. The device comprises a working head (30), an electric motor (4), a pump (20), a hydraulic reservoir (33), and a gear mechanism (19) extending between the electric motor (4) and the pump (20). A holding area (5) around which a hand is placed is provided and an actuating switch (39) is assigned to this area. The aim of the invention is to improve a pressing device of this type with regard to the handling thereof. To this end, the invention provides that the holding area (5) is formed around the electric motor (4), and the actuating switch (39) is situated between the electric motor (4) and the working head.
Claims10
Electrohydraulic pressing device comprising:
- a working head, an electric motor, a pump, a hydraulic tank and a gear mechanism between the electric motor and the pump, a gripping region being provided around which a hand can be placed and with which an actuating switch is associated, and having a working piston for the actuation of a pressing tool, wherein when the device is actuated, the working piston can be made to move in first instance into a holding position and then can be made to move into the pressing position.
Method for operating an electrohydraulic pressing device comprising the steps of:
- providing an electrohydraulic pressing device comprising;
- a working head, an electric motor, a pump, a hydraulic tank and a gear mechanism between the electric motor and the pump, a gripping region being provided around which a hand can be placed and with which an actuating switch is associated, and a working piston for the actuation of the pressing device;
- moving the working piston into a holding position, wherein the force acting on the workpiece in said holding position is substantially less than the maximum pressing force;
- holding the working piston in the holding position;
- moving the working piston to a pressing position.
