Thermoforming Apparatus Having Deformation Sensor and Method

A thermoforming apparatus is provided having a pair of coacting platens, a load bearing structural member, a force applicator, and a deformation sensor. The pair of coacting platens and respective dies are configured to mate on opposed surfaces of a heated sheet of thermoformable material to form articles. The load bearing structural member is configured to carry the coacting platens and the dies in complementary closed relationship about the sheet during an article forming operation. The force applicator is carried by the structural member and configured to impart a forming load between the pair of opposed dies and platens and across the structural member during a forming operation. The deformation sensor is configured to span a first location and a second location on the structural member to detect deformation indicative of separation between the dies resulting from deformation. A method is also provided.

SERVO PRESS MACHINE AND SETTING METHOD FOR SERVO PRESS MACHINE
20190291375 · 2019-09-26 ·

A servo press machine includes a display unit that displays a strip-shaped region for setting a motion of a slide and an operation unit that receives an input operation. A range extending from an upper end of the strip-shaped region to a lower end thereof corresponds to a movement range of the slide in a linear movement, and the strip-shaped region is formed of a plurality of slide operation regions that are consecutive in a direction in which the strip-shaped region extends. Each of the slide operation regions can set a speed of the slide in response to the input operation received by the operation unit, and a boundary between adjacent two of slide operation regions can move along the direction in which the strip-shaped region extends in response to the input operation received by the operation unit.

Adjustable clamshell press
10421207 · 2019-09-24 · ·

A clamshell die cutting press (10) that can transition between an opening of three inches and 0.937 and anywhere in between without the requirement of filler plates. This is accomplished by attaching the connecting rod or arm (20) that extends between the fixed platen (14) and the movable platen (16) to the fixed platen through an eccentric bevel gear (26). The bevel gear (26) is driven by an electric motor (28) which allows the adjustment to be made with a push of a button, and by moving the bridge rocker plates (34 and 36) and bridge cam stands using linear slides and servo motors.
