Shear-line multi-axis numerical control system based on P500 controller

Abstract

A shear-line multi-axis numerical control system based on a P500 controller has a P500 controller, which serves as a hardware carrier of the shear-line multi-axis numerical control system and communicates respectively with a remote input/output module and at least three servo driving units in a high speed through EtherCAT on-site buses. The servo driving units corresponding drive servo motors. The remote input/output module is in communication connection with a digital quantity/analog quantity device and at least three hydraulic execution units to complete data acquisition and accurately positioning of numerical control shafts of a shear line during a production process. The shear-line multi-axis numerical control system comprises a man-machine interface module, a PLC logic processing module, an embedded high-precision real-time system module, a digital shaft motion control module, a synchronous sub-module and a simulated shaft motion control module. The shear-line multi-axis numerical control system has high performance-price ratio, flexible functions and excellent data interaction performance. Precise positioning and process synchronization of a plurality of numerical control shafts on a shear line are realized, and centralized control is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical automation control, in particular to a shear line multi-axis numerical control system based on a P500 controller, which is used in numerical control control occasions with a high degree of automation. Background technique [0002] At present, most of the electrical control systems used for steel plate shearing lines in the domestic market use imported shearing machine numerical control systems, which are combined with programmable logic controllers PLC and human-machine interface terminal operators HMI to form a control framework. Among them, imported shearing machine numerical control systems Most of the systems use the DAC350, 360 produced by the Netherlands DELEM company or the DNC61G CUT produced by the Swiss CYBELEC company and other special CNC systems for shearing machines. The above-mentioned control architecture is not only costly, but also the data bus communication between the numeri...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of high cost, inconvenient operation, and poor data interaction of the current cutting line numerical control system. It is used to control two digital axes on a single shearing machine at most, and it cannot control multiple axes at the same time to realize parallel shearing. For the problem of the action of auxiliary mechanisms such as front feeding, side feeding and rear feeding on the tangent line, a multi-axis CNC system based on the P500 controller is provided for this purpose
