Die assemblies for forming a firearm projectile and methods of utilizing the die assemblies are disclosed herein. The die assemblies include a forming die, a first punch, and a second punch. The forming die defines a first side, a second side that is opposed to the first side, and a die cavity that extends between the first side and the second side. The first punch is configured to seal against the forming die from the first side. The second punch is configured to be received within the die cavity from the second side. When the first punch seals against the forming die and the second punch is received within the die cavity, the first punch, the second punch, and the forming die collectively define a forming surface shaped to define an external contour of the firearm projectile.

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 pneumatic chamber 20 is configured to include a first pneumatic chamber 21 pressurizing a first piston 11 and a second pneumatic chamber 22 pressurizing a second piston 12. The first pneumatic chamber 21 communicates with the second pneumatic chamber 22. The hydraulic pressure generating unit 55 is internally provided with a hydraulic chamber 30, and the hydraulic chamber 30 is configured to have a first hydraulic chamber 31 pressurized by the first pneumatic chamber 21 via the first piston 11 and a second hydraulic chamber 32 pressurized by the second pneumatic chamber 22 via the second piston 12. The hydraulic pressure generating unit 55 is movable in a thrust direction in a cylinder 2, and the second hydraulic chamber 32 has a function of fixing the moving hydraulic pressure generating unit 55 in the cylinder 2 by causing a thin portion 15 to be elastically deformed in a radial direction due to hydraulic pressure. The first hydraulic chamber 31 outputs hydraulic pressure of the first hydraulic chamber 31, which is increased by the fixing, to an output rod 7.

A fluid forming apparatus includes a main frame having at least two tensile frame struts extending along a clamping axis and adapted to carry a tensile force along the clamping axis. An upper pressure plate and a lower pressure plate are arranged inside a frame space, and a tool space is disposed between the upper and the lower pressure plate, the tool space being adapted to take up a fluid forming tool mold. A first closure pressing unit is arranged inside the frame space such that by a pressure force exerted by the closure pressing unit, a pressure closing force along the clamping axis is exerted onto the upper and lower pressure plates, wherein the upper pressure plate, the lower pressure plate, the tool space and the first closure pressing unit are arranged in a functional serial arrangement along the clamping axis.

A standalone waste compacting device includes an enclosure having a removable bin; a cover section on the enclosure incorporating at least one solar power unit, at least one storage battery and control unit, at least one inwardly pivoting user access flap having a dual locking control mechanism, at least one recessed foot pedal mechanism for opening the access flap, a detachable independent compaction unit comprising a scissor linkage and lever linkage system, and at least one service access means.

A pressure pin of a press, in particular a forming press, for transferring a force to a tool component of the press includes a pin body, a sensor element arranged in the pin body for measuring a force which can be transferred via the pressure pin, and an actuator unit arranged in the pin body which has a functional body made of an adaptive material. The adaptive material is designed such that the rheological properties thereof and/or the length thereof and/or the volume thereof can be selectively modified as a function of an electrical and/or magnetic field.

A trash compacting apparatus including a container, an air pump, two or more inflatable air bladders, an air distributor, a load plate, a load sensor, a pressure sensor, a controller unit, and an interface unit is disclosed herein. The apparatus may operate as a standard trash container and may further include a lid. The apparatus may be operated by the user or by a programmable controller unit to inflate the air bladders, thereby compressing trash contained within the apparatus and reducing the total volume of the trash.
