Controller for bending and forming wire rod

Abstract

The invention discloses a controller for bending and forming a wire rod, which integrates a programmable logic controller module, an input/output module, a motion control module, a human-computer interface module, an instant data exchange module and a three-dimensional analog module; and a universal flexible workpiece is processed by matching with a wire rod-bending forming machine. In the controller, wire rod-bending steps of feeding a wire, tilting and bending an angle of the workpiece are set on a conversational editing interface of the human-computer interface module; after the editing is completed, an actual control command is obtained through conversion and three-dimensional simulation and previewing are carried out according to a die geometrical relation; and after a formed resulted is confirmed to be correct and the process is ensured not to be interfered, the control command is actually output to a machine for processing. Software and hardware required by the controller are integrated into a single controller so as to improve the functionality of the controller, reduce wiring of a machine, lower maintenance costs and simplify an upgrading program of a control system.

Description

Technical field: [0001] The present invention relates to a wire bending forming controller applied to a bending wire forming machine, especially a wire bending that can plan and input processing programs through a man-machine interface module and can simultaneously perform 3D simulation and preview Forming controller. Background technique: [0002] There are various wire bending machines with different functions on the market, such as the Chinese patent announcement CN201231294 "Numerical Control Wire Bending Machine", which provides a wire bending machine with a rotatable head and is suitable for materials with different wire diameters. The advantages of high degree and high processing precision. [0003] The wire bending machine is equipped with a machine base, a whole wire mechanism, a wire feeding mechanism and an adjustable wire device. According to the required wire bending angle and wire cutting length requirements, the operator inputs the command program in advance...

Problems solved by technology

[0004] The "Shaping device of a wire bending machine" of US Patent 6101860 provides a multi-directional tool erection structure, which has a higher degree of freedom in the installation of tools and molds. Through the wire feeding and the whole line servo mechanism, more complex shapes can be formed. The result of flexible materials, but because of the increase in complexity and freedom, users also increase the difficulty of use

[0005] The above-mentioned flexible forming machine performs wire bending and forming. After editing the processing program, it is often through the actual operation of the machine and the results of wire forming to confirm whether it meets the processing requirements. For experienced operators in this industry, it may be For workpieces with a relatively simple appearance, the processing formula can be edited and predicted by referring to past experience and intuition, but if it is programmed by a novice, or for a complex polyline shape, it will take a lot of time to adjust the processing formula. In addition to the time cost, the material cost is also considerable

[0006] What's more serious, even mechanical interference will be caused during the process of processing and testing, resulting in equipment damage

Furthermore, the bending angle of the wire and the servo motor commands required by the mold are in a non-linear relationship. In addition to the elastic properties of flexible materials, the user must try a variety of mold rotation angles before forming the desired bending angle. This process is a time-consuming and material-consuming program editing method
