Retrofit systems for converting a manual press to an automated press. The retrofit systems include a first shaft, a second shaft, a first spacer, and a second spacer. The first shaft is mounted to a first vertical member and is coupled to a first cross member and to a second cross member. The second shaft is mounted to a second vertical member and is coupled to the first cross member and to the second cross member. The first spacer is supported by the first shaft and is disposed between the first vertical member and the first cross member. The second spacer is supported by the second shaft and is disposed between the second vertical member and the first cross member. The first spacer and the second spacer are selected to increase the space between the first cross member and the second cross member to accommodate an automatically actuated press.

A pressing machine is described for plastically deforming a tubular workpiece, in particular a fitting. The pressing machine has a motor, and pressing jaws which are driven by the motor and can apply a force to the workpiece during operation. The pressing machine also has a power transmission unit coupled to the motor and the pressing jaws for transmitting power from the motor to the pressing jaws. The pressing machine also has at least one sensor unit for measuring at least one pressing parameter P and a controller which receives the currently measured value of the pressing parameter P from the sensor unit and determines therewith the pitch or slope of a press parameter curve K of the press parameter P. The controller terminates a pressing operation before reaching a maximum possible pressing force Pmax when the pitch or slope of the press parameter curve K of the press parameter P satisfies a shutdown criterion. Also described is a corresponding method for operating a pressing machine.

Disclosed is a piston-cylinder assembly of a hydraulic press, which includes a basic cylinder and a first and second piston. A ring cylinder is formed above the basic cylinder as a continuation of the cylinder structure. The first piston is located inside the basic cylinder in the bottom part of the basic cylinder and the second piston is located above the first piston in the top part of the cylinder structure. The piston-cylinder assembly has a first hydraulic fluid space below the first piston and a second hydraulic fluid space below the second piston and the piston-cylinder assembly includes a unified hydraulic fluid channel in flow connection to the first hydraulic fluid space in order to provide a pressure effect in the first piston and to the second hydraulic fluid space in order to provide a pressure effect in the second piston.

A hydraulic extrusion press includes at least one ram, the ram being driven by hydraulic oil from a main line and a hydraulic control pressure being used to control the extrusion press. To minimize non-productive periods, the control pressure is also supplied to the main line. The main line and the pressure control system are connected with one another on the pressure side.

A safety power assist for a manual press is provided. In another aspect, a press includes a tool, a manual actuator, a switch and an automatically powered actuator. A further aspect of the present press employs a spring which must be compressed beyond a predetermined pinching force before a switch is activated, where switch activation causes an automatically powered actuator to advance a workpiece-contacting punch or tool.

A can compression equipment is provided and belong to the field of recycling of renewable resources and environmental protection. The can compression equipment includes: a frame; a pressing block arranged at an end of an interior of the frame, an accommodating space being defined between the pressing block and a bottom of the frame and configured for accommodating the can to-be-compressed; and, a driving device connected to the pressing block and configured for driving the pressing block to move forward or backward along a lengthwise direction of the frame to change a size of the accommodating space. Instead of using manpower to compress the can, the can compression equipment can save time and manpower, and further effectively reduce a volume of the can as small as possible.
