摘要： A heat press dual-zone temperature control system includes a first plate including an internal heating element and a first temperature sensor and a second plate including an internal heating element and a second temperature sensor. The first plate is arranged adjacent and parallel with the second plate. A controller is configured to provide temperature control, including controlling a temperature of the first plate to a first setpoint based on information from the first temperature sensor, and independently controlling a temperature of the second plate to a second setpoint based on information from the second temperature sensor. A user interface is communicatively coupled with the controller. The user interface includes a first zone configured to receive user input for the first plate and to display information about the first plate, and a second zone configured to receive user input for the second plate and to display information about the second plate.

The hydraulic press also comprises a pressure accumulator (4) as well as a hydraulic circuit with valves. Inside the working piston (7) moved by hydraulic pressure, a striking piston (7) moving along with the working piston (3) and quickly movable relative to the working piston (3) by means of hydraulic pressure, is provided. In addition, a separate impact body (10) is provided between the striking piston (7) and the object (14) pressed by the hydraulic press.

摘要： A device and method for operating a motor-actuated working device is provided. A certain working operation requires a rise in an applied force to a certain working force. The device enables a rise in the force to a general working force that exceeds the certain working force and an apparatus is provided for monitoring the device value. For the certain working operation, an evaluation is performed to detect the characteristic change and that the attainment of the characteristic change is used as a signal for ending the certain working operation after the certain working force has been attained but before the general working force has been attained.

摘要： A closed-circuit, self-contained hydraulic axis includes an electric motor, a hydraulic cylinder configured to be connected to a load and a main pump driven by the electric motor to pump hydraulic fluid through the circuit. Pressure connections of the pump are connected to the respective chambers of the cylinder such that the cylinder rod is configured to extend and retract depending on a direction of flow of the hydraulic fluid through the main pump. The hydraulic axis includes a main accumulator connected to the pump via first control valve, an energy storage accumulator connected to the pump via a second control valve, and a charge pump. The hydraulic axis is switchable between a first operating mode that is free of energy storage in the energy storage accumulator, and a second operating mode in which energy is stored in the energy storage accumulator.

摘要： An electro-hydrostatic actuator system for a press drive, having an upper piston with a press surface, which acts from a first direction, wherein the press surface of the upper piston is actuated by means of a piston rod in a hydraulic cylinder of the upper piston and traverses a first distance in a press run, and a first electro-hydrostatic actuator for driving the upper piston, comprising a first pump and a first motor generators which is controlled by a first controller. The system furthermore comprises at least one auxiliary piston with a press surface, which acts from a second direction opposite the first direction, wherein the press surface of the auxiliary piston is actuated by means of a piston rod in a hydraulic cylinder of the auxiliary piston and traverses a second distance in the press run, and a second electro-hydrostatic actuator for driving the at least one auxiliary piston, comprising a second pump and a second motor generator which is controlled by a second controller. The second motor generator is operated as a generator in the press run, thereby generating energy which is provided to the first motor generator or auxiliary piston, which are operated as motors, via the common DC bus.

摘要： An automatic can crusher apparatus for crushing cans for recycling includes a housing having a ram aperture extending through to a housing inside. A ram has a pneumatic cylinder body, a ram arm extending through the ram aperture, and a ram head coupled to the ram arm. The ram moves the ram head between a load position and a crush position adjacent a housing right side. A can positioner is coupled to a housing left side within the housing inside to secure a can adjacent the ram head in the load position. A feeder chute is coupled to the housing top side to receive a plurality of cans through a chute top end and dispense each can through a chute bottom end onto the can positioner when the ram head is in the load position.
