Calibration method for rotor-free vulcameter torque calibrator

Abstract

The invention provides a calibration method for a rotor-free vulcameter torque calibrator. The method comprises the following steps of fixing the torque calibrator on a calibration device, additionally hanging a weight on a lever of the calibration device to enable the torque calibrator to be twisted to a nominal angle and reading a torque indicating value T on the torque calibrator, and calculating a torque standard value T' according to a weight hung on the lever and calibrating the torque indicating value T based on the torque standard value T'. The invention also discloses a device used bythe calibration method, and the device enables the calibration precision to be obviously improved and the service life to be obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of measurement and measurement, in particular to a calibration method of a torque calibrator, and more particularly to a calibration method of a rotorless vulcanizer torque calibrator and a device used therein. Background technique [0002] During the rubber vulcanization process, under the conditions of temperature, pressure and time, the rubber macromolecules are cross-linked to form a three-dimensional network structure, so that the plasticity of the rubber material disappears, the elasticity increases, and the modulus increases. With the increase of the modulus, the rubber The strain generated by the material under stress decreases, and the stress required to generate the strain increases, so as to obtain the crosslinking performance of the rubber material. The rubber vulcanizer is to continuously measure all changes in the crosslinking performance of the rubber material during the rubber vulcanization pr...

Problems solved by technology

However, when the reference film is used for calibration, the price of the standard reference film is relatively high, and the reference film itself also has the problem of easy aging, which makes the calibration accuracy worse

When a conventional calibration device is used, the connection between the device and the torque calibrator is usually very complicated, and additional fixing devices are required, such as screw fixing so that screw holes need to be set on the torque, and the transfer calibration device and the torque calibrator are both A specific design is required to use the fixture, which is complex and expensive, or there is a gap in the connection between the alignment device and the torque scaler, which can cause calibration errors during rotational calibration
