METHOD AND DEVICE FOR MEASUREMENT OF TORQUE OF RECEIVING SHAFT OF HOT STAMPING PRESS FOR MEASUREMENT OF ITS FORCE Russian patent published in 2024 - IPC G01L1/06 

FIELD: measurement.

SUBSTANCE: invention relates to forging equipment, namely to devices for measuring press forces. In the developed invention, the frequency optoelectronic sensors of the rotating receiving shaft of the press are fixed at the edges of its base section, at that, the developed design of frequency sensors allows to eliminate their angular displacements relative to the receiving shaft and longitudinal linear displacements. Opposite optoelectronic pairs of frequency sensors, on the rotating receiving shaft there are measuring tapes "zebra". During the rotation of the receiving shaft, the tape is continuously irradiated with infrared radiation from the sensors and reflected light infrared pulses are received, which are then converted into a sequence of electrical pulses and transmitted to inputs of two low-frequency filters, after which the obtained signals are transmitted to inputs of a digital phase meter with a microprocessor system. According to the method, a time method of measuring phase shift is used, twisting angles, maximum deformations and torques of the rotating take-up shaft of the press are measured at different modes of its operation in the process of stamping.

EFFECT: possibility of determining the current torque of the rotating receiving shaft of a hot-stamping press (THSP), stability of measurement of the press force, protection of the THSP during stamping forged pieces from process overloads and simplifying the design.
