Embodiment Construction

[0017] A temperature rise control method for a servo motor of a CNC brick tower punching machine, comprising the following steps:

[0018] The first step is to set three sets of motor parameters and process parameters on the NC;

[0019] In the second step, when the machine tool is running, the servo motor uses the first set of motor parameters and process parameters, and the PLC reads the motor temperature in real time; when the motor temperature read by the PLC does not exceed the set monitoring and warning temperature, the servo motor continues to use the first set Group motor parameters and process parameters;

[0020] In the third step, when the machine tool is running, the servo motor uses the first set of motor parameters and process parameters, and the PLC reads the motor temperature in real time; when the motor temperature read by the PLC exceeds the set monitoring and warning temperature, the PLC triggers the second NC asynchronous sub The program calls the second s...

Abstract

The invention relates to a numerical control turrent punch press servo motor temperature rise control method. The numerical control turrent punch press servo motor temperature rise control method comprises the following steps that three sets of motor parameters and technological parameters are set on an NC; when a machine tool runs, a servo motor uses the first set of motor parameters and technological parameters, and a PLC reads motor temperatures in real time; when the motor temperature read by the PLC is not higher than a set monitoring early-warning temperature, the servo motor continuously uses the first set of motor parameters and technological parameters; and when the motor temperature exceeds a monitoring early-warning temperature, the PLC triggers an NC asynchronous subprogram, the NC chooses the motor parameters and technological parameters according to the current temperature, and when the motor temperature is lowered to be below the monitoring early-warning temperature, theNC chooses the first set of motor parameters and technological parameters for use again. With the numerical control turrent punch press servo motor temperature rise control method, because regulationcan be carried out in real time, the motor is effectively protected, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to a method for controlling the temperature rise of a servo motor of a numerically controlled brick tower punching machine. Background technique [0002] As we all know, the turret punch press belongs to the punching machine in the field of sheet metal processing. It is a special high-speed sheet metal forming processing machine. Its function is to use the servo motor to drive the transmission mechanism to carry out high-speed and accurate feeding. Realization of functions such as rolling bars. In order to achieve high-speed feeding and cost control, the servo motor is usually used with overload, even in the case of extreme feeding, it is even used with an overload of about 2.5 times. High, bring great harm such as: [0003] (1) The motor temperature is too high to burn out the motor or encoder; [0004] (2) Reduce the service life of the motor; [0005] (3) The motor of the machine tool will alarm and stop when the temperatur...
