Abstract

The invention relates to an intelligent sawing band sawing machine. On the basis of the variable-frequency driver of a saw disc, a driving torque detecting device, a saw blade tension detecting device and an electro-hydraulic servo feeding device are added to a common numerical control band sawing machine, wherein the driving torque detecting device consists of an output current interface of the variable-frequency driver of the saw disc and an AD (analog-digital) conversion unit; the saw blade tension detecting device consists of a pressure sensor of a saw blade tension hydraulic cylinder andan AD conversion unit; and the electro-hydraulic servo feeding device consists of a displacement sensor of the saw frame feeding hydraulic cylinder, a whole machine controller, a three-position four-way electro-hydraulic proportional valve and a driving amplification circuit board. Therefore, the sawing power born by a band saw blade in the whole sawing process is constant, and the sawing efficiency of the sewing machine and the service life of the band saw blade are improved.

Description

technical field [0001] The invention relates to a metal band sawing machine, in particular to an intelligent sawing band sawing machine. Background technique [0002] Traditional band sawing machines generally include a bed, a saw frame installed on the bed, a saw blade, a saw disc, a saw frame feed hydraulic cylinder, a saw blade tensioning mechanism, a main drive, a hydraulic system and an electrical control system, etc. The cylinder is connected to the saw frame and drives it to feed and cut. The saw blade tensioning mechanism is connected to the saw disc through the saw blade tensioning hydraulic cylinder to adjust the tightness of the saw blade. When the band sawing machine is working, the speed of the saw disc, the tension pressure of the saw blade tension hydraulic cylinder and the displacement of the saw frame driven by the saw frame feed hydraulic cylinder are the three most important factors affecting the sawing process and effect. Before the traditional band sawi...
