An apparatus for crushing aluminum beverage cans, including; a containment structure with an integral crushing chamber, a pneumatic crushing cylinder with a hub type crushing head which ensures the can remains inside the crushing chamber during the crushing event, an ejection cylinder with an ejection ram, solenoid control valves, a safety interlock switch and a 3 position control switch, an air/gas supply and distribution system and an electrical control system. Two pneumatic cylinders; which are supplied air via two 3-way solenoid control valves, are used to perform the crushing and ejection work. Simultaneous two handed switch operation is required to energize either of the 3-way solenoid control valves to route air to the pneumatic cylinders. Two handed switch operation ensures that the operator's hands are free of the crushing chamber during operation.

A housing of a radial press has a casing section and an annular end-face support disc. An annular structure is movably guided in the housing along a press axis, and multiple press jaws arranged about the press axis are supported on the support disc so as to be movably guided in the radial direction. The annular structure acts on the press jaws by means of control surfaces which are inclined relative to the press axis and which lie against press jaw counter surfaces designed in the form of sliding surfaces. The end face of the ring structure facing the support disc is designed with axial protrusions. Each control surface protrudes into the radial inner surface of one such protrusion, and the support disc has recesses which are paired with the protrusions and into which the protrusions enter when the radial press is closed.

The press machine includes: a hydraulic cylinder configured to drive a slide; a plurality of hydraulic pumps/motors; a first port of each of which is connected to a first pressurizing chamber of the hydraulic cylinder; a plurality of servomotors axially connected to rotating shafts of the respective hydraulic pumps/motors respectively; a low-pressure accumulator to which second ports of the hydraulic pumps/motors are each connected; a high-pressure accumulator connected to a second pressurizing chamber of the hydraulic cylinder; and a slide position controller configured to control the servomotors so that a position of the slide matches a position corresponding to a slide position command signal based on the slide position command signal from a slide position commander and a slide position signal from a slide position detector.

An inner-circulating high speed hydraulic system, a hydraulic platform and a hydraulic platform assembly consisting of said systems, wherein the inner-circulating high speed hydraulic system comprises a hydraulic cylinder component and a pressure valve component, the hydraulic cylinder component including a high pressure cylinder, a hydraulic plunger, and a housing, wherein an axial hole and radial holes intersecting with the axial hole are disposed at the top/bottom of the high pressure cylinder and the high pressure cylinder is contained within the housing, wherein the inner-circulating oil chamber may communicate with the axial hole via the radial holes and further communicate with chambers at the top/bottom of the hydraulic plunger, wherein compressed air inlets are disposed on the housing and a lower end of the hydraulic plunger is connected to an actuating element; and a pressure valve component, comprising a pressure servo motor and a pressure plunger driven by the pressure servo motor to move up and down within the axial hole disposed at the top/bottom of the high pressure cylinder. Accurate control on dwell time for pressing at the up and down stop points of the platform, and highly precise adjustment to duration of the dwell time are enabled by the present invention. Thus, a stamping process with high quality is achieved.

A modular pressing device capable of generating stage downward forces is provided. The modular pressing device comprises a non-exchangeable pressing module and an exchangeable pressing module. The non-exchangeable pressing module includes a first downward force generating unit. The exchangeable pressing module includes a second downward force generating unit. The first downward force generating unit applies a first downward force to at least one of a testing seat and an electronic device through the exchangeable pressing module. The second downward force generating unit applies a second downward force to the electronic device. Thereby, the modular pressing device is capable to generate two different downward forces to reduce the downward surge force. In addition, as the exchangeable pressing module is worn, the exchangeable pressing module can be replaced quickly such that the maintenance cost can be effectively reduced and the stability of the apparatus can be enhanced.
