Disclosed herein are an electric press and a method for calibrating the electric press, which can implement a rapid calibration operation. An electric press (10) includes a ram location information storage unit (63) and a load control unit (64). The ram location information storage unit (63) stores ram location information, corresponding to actual load values and representing locations to which a ram is moved, in advance. The load control unit (64) applies an actual load, corresponding to at least one location which belongs to the locations represented by the ram location information and to which the ram is moved, to a compression target by moving the ram to the location. Accordingly, the load value output by the detection unit is calibrated based on the actual load value applied to the compression target.

Disclosed herein is a press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors configured to provide a first output signal indicative of deformation of the first sensing part. The method can be configured for determining if an error criterion based on the first output signal from the first displacement sensor has been met, and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.

A sintering press for sintering electronic components on a substrate includes at least one reaction element extending along an element axis parallel to a pressing axis of the sintering press between a first element end and a second element end, the first element end forming a support plane for a respective substrate, at least one load cell operatively connected to the second element end, and an element plate slidably supporting the at least one reaction element and equipped with a heating circuit. The reaction element has a heating portion passing through the element plate and transmitting by conduction heat of the element plate to the substrate. The reaction element has a cooling portion ending with the second element end and shaped to dissipate the heat transmitted from the element plate to the heating portion.

The invention relates to a crimping pliers force sensor. The crimping pliers force sensor comprises a transfer body which is contacted by a die half and a supporting body. At least one piezoelectric film is arranged between the transfer body and the supporting body. The transfer body and the supporting body comprise protrusions and recesses. By the protrusions and recesses the transfer body is floatingly accommodated in the supporting body with the provision of a guidance in a transversal plane.

A pressing tool for pressing workpieces is described. The pressing tool comprises a hydraulic pump for conveying a hydraulic fluid, an electric motor for driving the hydraulic pump, a working cylinder which is hydraulically connected to an outlet of the hydraulic pump, a pressure-relief valve which is hydraulically connected to the outlet of the hydraulic pump and which opens at a certain predefined pressure P.sub.v of the hydraulic fluid, an electronic control for controlling the electric motor and a sensor 60 which monitors the state of the pressure-relief valve and emits a signal which describes the state of the pressure-relief valve to the electronic control. Furthermore, a method of operating such a pressing tool is described.

Press-fitting work is evaluated by appropriately determining a load when sliding occurs. A load-drop determination unit determines whether or not a load value detected by a load detecting unit exceeds a load-drop determination value decided based on a moving average value and a dispersion average value stored in a storage unit. A data substitution unit substitutes the load value which is determined to exceed the load-drop determination value in the load-drop determination unit with a predetermined value.

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.

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 hand-operated screw press for users to press cannabis flower or isolated trichome heads without an air compressor, hydraulic unit or solvents used in the process. A digital load cell is provided, as is a full color LCD touch screen display for showing and recording force in real time. A mechanism for detecting the end point of a process is also provided. A recipe representative of heat plate temperature, time of operation, pressure ramping, capacity of the screw press, type of raw material, or mass of raw material can be created and stored for use on any suitable rosin press machine.

A die clearance monitoring system includes a light source, a light detector, and a controller. The light source is disposed along a front side of a die set of a crimping device and emits light towards the die set. The die set includes a first crimp die and a second crimp die that engage and crimp an object along a crimp stroke. The light detector is disposed along a rear side of the die set. The light detector receives the emitted light from the light source that traverses across the die set through a gap defined between the first and second crimp dies and generates light absorption data based on the emitted light that is received. The controller is communicatively connected to the light detector. The controller processes the light absorption data to determine a relative spacing between the first crimp die and the second crimp die.
