Abstract

The invention discloses a double-pulse characteristics-based metal band saw sawing device and a double-pulse characteristics-based metal band saw sawing method. The conventional metal band saw has the technical defects of lower sawing efficiency and greater noises. The double-pulse characteristics-based metal band saw sawing device comprises a first eddy current sensor, a second eddy current sensor, a first mounting bracket, a second mounting bracket, a preamplifier, a conversion plate, a data acquisition card, a first high-frequency response proportional valve, a second high-frequency response proportional valve, a transverse tensioning hydraulic cylinder, a longitudinal vibration hydraulic cylinder, an industrial personal computer and an electromagnetic relief valve. The device is simple in hardware structure, high in reliability, convenient to maintain and upgrade, is conveniently assembled with a sawing machine and meets field environment requirements; a detection device has high response frequency, large information storage amount, high precision and high adaptive capacity.

Description

technical field [0001] The invention relates to a metal band saw sawing method and device, in particular to a metal band saw sawing device and method based on double-pulse characteristics. Background technique [0002] The metal band saw blade is the core component of the band saw machine. When the band saw blade cuts the workpiece, it will cause forced vibration due to various reasons, thereby reducing the surface quality and processing efficiency of the workpiece, and there will be a lot of noise. The electro-hydraulic servo system is a feedback control system composed of an electric signal processing device and a hydraulic power mechanism. It has many advantages, the most prominent of which are fast response, high output power and high control accuracy. Therefore, the development of a metal band saw sawing method and device based on double pulse characteristics is of great significance for the study of high precision, high efficiency and low noise for metal band sawing m...
