Abstract

The invention relates to a band sawing machine constant power sawing control method and an intelligent band sawing machine thereof; the intelligent band sawing machine comprises a control system, a saw frame system, a feeding system and a clamp mechanism; a rotary encoder is arranged on a rotary shaft of a driven saw wheel, and rotary speed of the driven saw wheel is detected in real time; a power sensor detects a frequency converter feedback current, and the current value is sent to a lower computer through the rotary encoder; the lower computer collects the rotary speed and torque data of a main motor, uses a feeding flow valve control motor to adjust the opening of the feeding flow valve, thus changing lifting speed of an oil cylinder piston rod; the lower computer can adjust the pressure of an electric-hydraulic proportional overflow valve through sensor feedbacks, thus controlling tensile force of a tensioning oil cylinder. The power of the driving main motor is fully used, sawing condition influences on the saw blade life and different material feeding force limit conditions are considered, thus realizing intelligent sawing of the band sawing machine, and effectively prolonging fatigue life of the saw blade.

Description

technical field [0001] The invention relates to the technical field of band sawing machines, in particular to a control method for constant power sawing of a band sawing machine and an intelligent band sawing machine in consideration of the fatigue life of a saw blade and maximization of motor power utilization. Background technique [0002] Modern manufacturing industry is developing towards high efficiency, high precision and economy. As the starting point of metal cutting, sawing has become an important part of the process of parts processing. There is a big gap between domestic band sawing machine products and foreign advanced band sawing machine products, especially the problems of low intelligence and low sawing efficiency. As the first process of parts processing, the effect and efficiency of sawing often affect the efficiency of the entire production line. Improving the sawing efficiency of band sawing machines can prevent sawing from becoming the bottleneck of the...
