An example lavatory waste compartment includes a waste bin having a waste compartment for trash, a waste flap providing an opening into the waste compartment for insertion of the trash, and a manually operated trash compactor coupled to a ceiling. The manually operated trash compactor includes an expansion component connected to a compacting head, and a retraction component coupled to the expansion component to hold or retract the expansion component to a stowed position. An increase in temperature above a threshold temperature causes the retraction component to release the expansion component resulting in deployment of the compacting head into the waste bin. An actuation device is provided to deploy the expansion component from the stowed position, and when deployed, the expansion component blocks opening of the waste flap, and the retraction component causes the expansion component to retract to the stowed position via release of the actuation device.

The present invention discloses a device and method for installing and adjusting a sliding block of a multipoint crank press. The device comprises a crank, a connecting rod with an end provided with a U-shaped notch, a sliding block and an eccentric pin shaft micro-adjustment mechanism. The eccentric pin shaft micro-adjustment mechanism is installed at the joint between the connecting rod and the sliding block. The crank, the connecting rod and the sliding block of the multipoint press are normally machined and installed through a classical process, so that the sliding block of the multipoint press runs to a bottom dead center. A gap among mechanisms is eliminated through the loading by a hydraulic loader. The position of one set of crank, connecting rod and sliding block mechanism is taken as a reference, and then the eccentric positions and directions of the eccentric pin shafts at other adjustment positions are finely adjusted, thus realizing high-precision assembly and operation of the multipoint press.

A slide motion control apparatus for a mechanical press comprising: a slide which is disposed so as to be relatively vertically movable with respect to a driven body to which a drive force is transmitted through a con rod of the mechanical press; a relative position commander that outputs a relative position command indicating a relative position of the slide with respect to the driven body; a relative position detector that detects a relative position of the slide with respect to the driven body, and outputs a relative position detecting signal indicating the detected relative position; a servomotor; a drive mechanism that relatively moves the slide with respect to the driven body by a drive force of the servomotor; and a controller that controls the servomotor based on a relative position command signal output from the relative position commander, and the relative position detecting signal output from the relative position detector.

The invention relates to a method for compensating deviations in a deforming operation between two beams of a press, comprising of arranging one or more compensating element at a suitably chosen location in the press, detecting the deviations and moving the compensating element(s) relative to the beams by (electro) mechanical means during the deforming operation such that the detected deviations are compensated. The compensating elements can be moved here to an over-compensating position prior to the deforming operation and pressed out of their over-compensating position during the operation by the load on the beam, wherein each compensating element exerts an adjustable resistance force on surrounding parts of the press. It is conversely possible for the compensating elements each to be pressed stepwise to a position compensating the detected deviations during the deforming operation. It is possible to use (piezoelectric) actuators to exert the resistance force and/or to move the compensating elements. The invention further relates to a device with which this compensation method can be performed.

The present application describes a system to compensate deformations in press bending machines, in particular press bending machines used for plate conformation or bending, which comprises a group of uprights (1) for supporting the upper apron (7) of the press bending machine, wherein each upright (1) comprises two beams (2,3) placed on the upper and lower ends of a pillar (4) being coupled thereof by means of fastening means (5) and a compensation actuator (6) placed between the beams (2,3) and coupled to the beam (3) at one end thereof. The presented technology allows to increase the distance between the aprons of the press bending machine and the upright scye (1) so that said press bending machine allow the plate deformation in various shapes and dimensions.

There is provided a press brake that improves bending accuracy of a partial bending method. The press brake includes: a conveying mechanism that intermittently conveys a workpiece; a die; a punch; a crowning mechanism; a bending amount measuring device; and a control device. The control device presses an end portion of the workpiece in a conveying direction by the punch and conveys the workpiece by the conveying mechanism until the pressed portion enters into a measurement range of the bending amount measuring device. The control device drives the crowning mechanism so as to correct a crowning amount in accordance with a difference between a middle bending amount and an end bending amount measured by the bending amount measuring device.

Provided is a drive device for an electric servo press machine, the drive device including: left and right drive shafts rotationally driven by left and right electric servo motors; main pinion gears provided to the left and right drive shafts; main gears meshed with the main pinion gears; connecting rods connected to the main gears; and a slide supported thereby. Further, idle gears can be provided between the main gears.

The present invention relates to a press part (1,20,30,40) for supporting a mould part for encapsulating electronic components mounted on a carrier comprising a press block (2, 42), which press block comprises a contact surface (3), a side (4) facing away from the contact surface and at least one side wall (5) connecting the contact surface (3) and the side (4) facing away from the contact surface (3), wherein the press block (2, 42) comprises at least two opposed elements (6a, 6b, 21a, 21b, 31a, 31b, 31c, 31d, 44) protruding from the side wall (5), and wherein the side wall (5) transposes via only a recess (7) into each of the protruding elements (6a, 6b, 21a 21b, 31a 31b, 31c 31d 44). The present invention further relates to a press comprising the press part of the present invention.

A press ram for a fine blanking press comprises a ram plate section configured to carry a fine blanking tool and at least two guide sections positioned on opposing sides of the ram plate section. The ram plate section comprises an upper surface, a lower surface, and two opposing side surfaces. The at least two guide sections of the ram plate section are configured to guide movement of the press ram relative to a press frame during a fine blanking process. The at least two guide sections extend in a vertical direction to a level that is higher than the upper side of the ram plate section.
