Abstract

The invention discloses an all-electric bending machine system in the technical field of all-electric bending machines with a grating ruler compensating the bending depth, including S1: servo increases two parameters per step, Δ and time; Depth H, correction depth C, bending width L, bending force F, changeable), time=0, power on or call another program, each step time=0; time_now=Tmax; Tmax can be set to 5min or other experience Time, S3: start, read the parameters of the current step, the grating scale compensates the bending depth of the all-electric bending machine system, by increasing the Δ compensation value, when the bending machine performs continuous bending, the compensation value is continuously updated to Eliminate the accumulated error during bending, ensure that the bending accuracy is high under continuous operation, and the bending is in place at one time, saving compensation time and improving processing efficiency.

Description

technical field [0001] The invention relates to the technical field of all-electric bending machines, in particular to an all-electric bending machine system for compensating bending depth with a grating ruler. Background technique [0002] The all-electric (servo) bending machine is two high-power servo motors installed on both sides of the machine. The pulley drives the screw to rotate, so that the slider moves up and down synchronously, so as to bend the workpiece and process the product. Due to the large pressure required for folding the plate, the frame is deformed or the belt is stretched and deformed, resulting in the position of the Y-axis servo encoder reaching the given bending position, but the actual slider position has not been reached. Due to the amount of deformation, there are many influencing factors , it is difficult to calculate theoretically, that is, it is difficult to predict, so it cannot be in place at one time [0003] There are two existing solutio...

Problems solved by technology

Due to the great pressure required when folding the plate, the frame is deformed or the belt is stretched and deformed, causing the position of the Y-axis servo encoder to reach the given bending position, but the actual slider position does not reach it. Due to the amount of deformation, there are many influencing factors. , it is difficult to calculate theoretically, that is, it is difficult to predict, so it cannot be done at one time

[0003] There are two existing schemes, the two-stage bending method and the compensation bending method. When the two-stage bending method is close to the target and switches to another stage, the speed drops very low (if it does not drop very low, it will decelerate and stop when it is in place, and it will overshoot. ), the efficiency decreases

If the grating ruler breaks during bending, the slider will keep pressing down, causing a safety risk. The compensation bending method first judges that the servo positioning is completed, and then compares the position to compensate. There will be a sense of pause, and the time will be longer. Efficiency Therefore, we propose an all-electric bending machine system that compensates the bending depth with a grating ruler
