Abstract: The invention relates to a control and regulating device for a drive arrangement of a displaceable press beam of a bending press in particular a press brake, comprising a protective housing having an access orifice for a foot of an operator, and comprising a pedal-type actuating element disposed in the protective housing At least one detection means connected so as to communicate with a control and monitoring system of the bending press is assigned to the actuating element and is provided in the form of a motion profile detection means.

Abstract: Systems and methods to generate weather alerts are provided. A particular system includes one or more sensors to detect weather data. The system also includes a weather band radio receiver to receive weather alert messages. The system also includes a processor to perform an analysis of the weather data, to determine based on the analysis whether the weather data indicates a dangerous storm condition, and to initiate a first alert when the analysis indicates the dangerous storm condition and a weather alert message has been received. The first alert is not initiated when the weather alert message is received and the analysis does not indicate the dangerous storm condition.

Abstract: Roll grooving apparatus for rolling a circumferential groove in a pipe comprises a first support rotatably supporting a first grooving roll, a second support rotatably supporting a second grooving roll and being displaceable relative to the first support for displacing the second grooving roll toward and away from said first grooving roll, a stabilizer on the first support for stabilizing a pipe to be roll grooved, and first and second guards pivotally mounted on the second support for displacement therewith. The first guard engages the stabilizer, the second guard engages a pipe being roll grooved during a roll grooving operation and each guard is spring biased to engage the corresponding one of the stabilizer and a pipe being roll grooved. A member on the first support engages and displaces the second guard away from a pipe which has been roll grooved when the second support is displaced to move the second grooving roll away from the first grooving rolls.

Abstract: A pressing tool for coupling elements includes a forked receiver, a clamping claw which is interchangeably held in the receiver by a connecting pin, and a drive motor for the activation of the clamping claw. The connecting pin can be inserted through holes bored in the forked receiver and the clamping claw crosswise relative to the lengthwise direction of the housing of the pressing tool. A monitoring element is provided, which checks to ensure that the connecting pin is fully inserted. The monitoring element is connected to the power source of the drive motor by means of a switching element.

Abstract: A gear train locking mechanism for preventing the reciprocating slide of a mechanical power press from inadvertently moving during maintenance procedures and the like is disclosed. The gear train locking mechanism preferably includes an idler gear which is enmeshed with a drive gear of the power press and a movable arm assembly positioned for selectively engaging the idler gear to prevent its rotation. The engagement of the arm assembly and the idler gear effectively locks the gear train of the power press thereby preventing the slide of the power press from moving once the locking mechanism is activated.

Abstract: The present invention relates to a press machine that has a vertically movable ram for supporting upper or lower bending tools, said ram being integrally provided with an operation member, and a position determining member having an adjustable position located at a suitable point on said press machine such that when the operation member on the ram contacts the position determining member, the vertical movement of the ram is stopped. The press machine further includes a screw mechanism that is screw-coupled to the position determining member and is movable in an axial direction, a pulse motor drive unit which turns the threaded bolt, and a manual pulse generator for operating the pulse motor from a remote location.

Abstract: A power press is comprised of a frame, a stationary bed, a ram reciprocally movable toward and away from the bed and a safety guard for preventing movement of the ram toward the ram when the tooling for the press must be repaired or changed. The guard includes a first chain attached to the frame of the press and a second chain attached to the ram and attachable to the first chain to restrict movement of the ram toward the bed. The chains are connectable together at a plurality of locations to enable the combined, attached length of the chains to be adjusted. The adjustability permits the guard to be easily used with a press having a range of shut heights. A normally open power circuit controls the reciprocal movement of the ram. A key for closing the circuit by engagement with a receptacle in the circuit is attached to the first chain. The key is engageable with the receptacle when the chains are unattached and is not engageable with the receptacle when the chains are attached.

Abstract: A guard is disclosed for guarding the nip between a pair of rolls in a power roll mill to prevent the mill operator's fingers from being crushed between the rolls. The guard comprises an upstanding plate pivotally mounted transversely between the opposite side frame members of the rolling mill in front of the pair of rolls being guarded. The top of the guard is flat and is located adjacent and below the normal path for the infeed of a sheet of material being formed between the rolls in order that an operator's fingers which support the underside of the sheet will engage the guard and be prevented from entering the roll nip. The guard plate is depressibly supported at its opposite ends by a pair of upright tubular rocker arms which are pivoted at their base and are biased to a central neutral position. At least one microswitch is provided adjacent one of the rocker arms which is in electric circuit with an electric motor which drives the power rolls to turn the motor on and off.
