Problems solved by technology

Traditional stone cutting machines generally use manual loading, and manually push the stone in and out to control the cutting depth of the saw blade of the cutting machine. In this way, the real-time torque of the spindle motor cannot be detected. If the feed speed is too fast, the saw blade is easily stuck. In the stone, once the saw blade is stuck in the stone, the spindle motor will stop working, and all power consumption will be converted into heat energy in the motor winding
It is easy to burn the motor and even cause the production accident of the power grid

Abstract

The invention discloses a method for frequency conversion control of a stone cutting motor. The method includes the steps: (1) a controller extracts current and voltage information of the cutting spindle motor in real time; (2) the controller calculates real-time active power of the spindle motor according to real-time current and voltage of the spindle motor and compares the active power with a nominal voltage of the spindle motor to process correspondingly, and the controller outputs signals to control operating states of the spindle motor or control a feeding motor to increase feed quantity. Using the control method enables stone cutting operations to be more intelligent and more energy saving. The invention further discloses a device for frequency conversion control of the stone cutting motor, and the device comprises a portal frame, the spindle motor, a saw blade, a power source, a controller, the feeding motor, a spindle motor detection device, a strong-current frequency conversion circuit device and a spindle frequency conversion device. The control device has the advantages of accuracy in cutting, high operation efficiency and low cost.

Description

technical field [0001] The present invention relates to a frequency conversion control method, more specifically, to a stone cutting motor frequency conversion control method; the present invention also relates to a stone cutting motor frequency conversion control device. Background technique [0002] With the rapid development of the construction industry, people's demand for stone is increasing, and the stone processing industry has shown a huge market prospect, and the most important aspects in stone processing are technology and equipment. Traditional stone cutting machines generally use manual loading, and manually push the stone in and out to control the cutting depth of the saw blade of the cutting machine. In this way, the real-time torque of the spindle motor cannot be detected. If the feed speed is too fast, the saw blade is easily stuck. In the stone, once the saw blade is stuck in the stone, the spindle motor will stop working, and all power consumption will be c...
