The at least one strain gauge is secured on the spring element and located between the first side and the second side, wherein when the force is exerted on the spring element when the rotary motor is driven to move along the first direction, the second side is moved relative to the first side, the spring element is deformed, and the at least one strain gauge changes shape, so that the force is measured and standardized under a specific range.

An electric cylinder system includes: a rod; a ball screw mechanism; a nut connected to the rod; a cylindrical body including a contact portion, the contact portion configured to be abutting the nut making the linear motion, the cylindrical body configured to support the ball screw mechanism in such a manner that the ball screw mechanism is displaceable in the axis direction of the ball screw; a strain detector fixed to the cylindrical body and configured to detect a value corresponding to a displacement of the ball screw mechanism; and a control section configured to make the ball screw mechanism be displaced by making the nut abut against the contact portion, and configured to detect an abnormality of the strain detector based on the value detected by the strain detector according to the displacement of the ball screw mechanism.

A press machine includes: a press control unit that controls ascending/descending motion of the slide; and an abnormality diagnostic unit configured to perform abnormality diagnosis of the press machine based on data from a sensor provided in the press machine and to output a result of the abnormality diagnosis. The abnormality diagnostic unit is configured to perform the abnormality diagnosis, based on the data acquired from the sensor while the slide moves at a predetermined speed between a bottom dead point and a top dead point in a press-no-load state.

System for measuring misalignment of a tool (2) in a press device (1), the tool (2) comprises at least a first part (3) and a second part (4), which are movable relative to another in a guided manner by means of guide means comprising at least a guide pillar (10) provided in the first part (3) which is led in a guide bush (12) provided in the second part (4), wherein the system comprises measuring means (20) provided to detect misalignment of the tool (2). According to the invention, the measuring means (20) are mounted directly at the guide means.

The invention relates to a method for monitoring a high-pressure roller press in the course of comminuting, compacting, or briquetting material. The roller press has two rotationally driven press rollers, between which a rolling gap is formed with a gap width that can be modified during operation. During operation, operational data of the roller press is ascertained by one or more measurement value sensors and is stored on a computer. The method is characterized in that the operational data is stored as raw data on an edge computer, as an analysis computer, which is stationed locally in the region of the roller press and is connected to the measurement value sensors, and the raw data is evaluated on the analysis computer using an analysis algorithm so that characteristic data of the roller press is generated and stored on the analysis computer, wherein the characteristic data is transmitted from the analysis computer to at least one terminal via a wireless network and is displayed on the terminal.

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.

A semiconductor device is located between a first die-set part and a second die-set part of a press, and the first and second die-set parts are moved relative to each other for punching and shaping the semiconductor device therebetween. At least one parameter is monitored with at least one sensor attached to the first die-set part and/or the second die-set part at different positions of the first die-set part when it is moving relative to the second die-set part. Variations of the at least one parameter at different relative positions of the first and second die-set parts are compared, and a failure is determined to have occurred when the present variation of the parameter is different from its expected variation during normal operation of the press when there is no failure.

A terminal crimping machine includes a termination tool having crimp tooling defining a crimping zone that receives the terminal and the wire. The crimp tooling is actuated during a crimp stroke to crimp the terminal to the wire. The terminal crimping machine includes a wire clamp holding the wire near the crimping zone. The wire clamp releases the wire prior to completion of the crimp to allow extrusion of the wire during the crimping process. Optionally, the wire clamp may release the wire prior to bottom dead center of the crimp stroke. The wire clamp may release the wire after the terminal partially retains the wire.
