An all-electric bending machine system with grating ruler to compensate bending depth

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...

Examples

Embodiment

[0019] like figure 1 As shown, start the servo, edit the step, power on or call another program, time=0 for each step; time_now=Tmax; Tmax can be set to 5min or other empirical time, start, read the parameters of the current step, and judge the time_now-time and Tmax The size of the value between the two, if time_now-time
