Numerical control bender control system

Abstract

The invention provides a numerical control bender control system which has the advantages of stable performance, excellent man-machine interaction, high control precision, easy maintenance and little error of processed workpieces. The numerical control bender control system comprises a bending mechanical component, a servo hydraulic charging system and a servo motor, and is characterized by also comprising a touch screen and a programmable logical controller (PLC), wherein the touch screen is used for acquiring related bending parameter information input by a user and calculating effective data which can be used by the PLC directly, and parameters related to calculation in the acquired effective data includes target angle, upper die angle, lower die opening, lower die angle, back gauge position, material thickness and material width; and the parameters are used for calculating the back gauge position after conversion of pressure, depth feeding and correction, and the calculated back gauge position is sent to the PCL to control the operation of the bending mechanical component; according to the acquired data information, a relevant bending radius relation curve is fitted by a BP neural network, and the bending radius as a intermediate variable is used for calculating the effective data which can be used by the PLC directly.

Description

(1) Technical field [0001] The invention is applied in the technical field of industrial control and automation, and is specifically a control system of a numerical control bending machine. (2) Background technology [0002] Sheet metal bending forming has been widely used in sheet metal processing because of its good versatility, simple process and wide application range. A large number of sheet metal bending parts. CNC machine tools are mechatronic products that integrate electronic information technology and traditional machine tool technology, and are especially suitable for processing workpieces with complex shapes. Sheet metal bending is one of the most complicated processes in workpiece processing. On ordinary bending machines, it takes a long time to adjust to produce good workpieces. CNC bending machines can automatically calculate the mechanical position according to the angle, reducing the operation Difficulty, greatly shorten the adjustment time, improve the qu...

AI Technical Summary

Problems solved by technology

[0004] Although the CNC bending industry has developed greatly in recent years, there are still many deficiencies and defects, mainly as follows: the position calculation is not accurate enough, and the control accuracy is not enough

At present, there are some CNC bending machines at home and abroad, which have the function of angle programming. Due to the fact that the error is very large, some even have an error as high as several degrees, so that only rough machining of the workpiece can be performed.
