An extrusion system including a press with a chassis, a slider mounted to be mobile vertically on the chassis and an actuating arrangement that moves the slider, a hollow container receiving a billet and having at one end an extrusion die and at the other end a piston mobile in translation horizontally in the container, and a movement transformation system arranged between the slider and the piston to transform the vertical movement in translation of the slider into horizontal movement in translation of the piston. With an arrangement of this kind, it is possible to use a press of higher power.

A press machine is provided. Two vertical hydraulic cylinders are arranged on an upper beam plate of a press machine body, and the two hydraulic cylinders correspond to workbenches at corresponding positions in a one-to-one correspondence, constituting left and right working units, and a common mechanical drive unit and a common hydraulic drive unit are set for the left and right working units. The mechanical driving unit is composed of a driving motor through an electromagnetic clutch, an electromagnetic brake and lead screw nut driving mechanism driven by a gear pair. According to the load profiles during the working process of hydraulic press machine, the mechanical driving unit or the hydraulic driving unit are selected to provide energy for the two working units. A control method for the press machine, a press machine execution system and a control method for the press machine execution system are further involved.

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 filter press is disclosed for separating solid components from liquid components of a slurry. The filter press includes side beams and a plurality of filter plates oriented at right angles to the longitudinal direction of the side beams. The filter plates are adapted to move along the side beams. A stationary end is arranged on one end of the side beams and a movable head is adapted to transport the filter plates along the side beams. The filter press includes a press system adapted to exert a closing pressure on the filter plates to press the filter plates against each other. The press system further includes at least one electrically driven actuator adapted to generate an axially directed force on the filter plates by the movable head. The disclosure also relates to a method for separating the solid components from the liquid components of a slurry.

A press frame assembly includes a base plate, a load cell, and an overload protection element; a first plate, a plurality of guideposts disposed on the base plate; a plurality of springs disposed on the plurality of guideposts, a displacement transducer arranged to monitor a linear displacement of the first plate, and a controller, in communication with the load cell and the displacement transducer. The first plate is disposed to translate on the plurality of guideposts, and wherein the springs are disposed to urge movement of the first plate in relation to the base plate. The load cell is arranged to monitor a load exerted upon the base plate. The controller generates a signal that is based upon the load exerted upon the base plate or the linear displacement of the first plate in relation to the base plate.

Implementations of motorcycle base valve presses may include: a press including a base coupled to a first end of a body, a head coupled to a second end of the body, a handle coupled to a side of the head, and a press ram coupled through the head. The motorcycle base valve press may also include an end cap coupled with a first end of the press ram; and a motorcycle fork receiver coupled to the base of the press, the motorcycle fork receiver configured to receive a damper assembly of a motorcycle fork. The end cap may be configured to contact the base valve through the press ram and allow the base valve to turn.

A manually operated press comprising an actuating member coupled to a shaft, wherein an actuation of the actuating member is converted into a stroke movement of a press ram coupled to the shaft, and hence also into a change in a relative position of the press ram. The press furthermore comprises a reset mechanism for resetting the actuating member, which reset mechanism counteracts the actuation of the actuating member and causes a return movement of the press ram opposite the stroke movement. The reset mechanism comprises a spiral spring.
