Embodiment Construction

[0023] Refer to figure 1 , The present invention adopts a layered system structure, layering can realize isolation of each layer, and communication between layers is carried out through a standard interface. The first layer is the management. It is the management part of the system, which mainly realizes the interaction function between the user and the software, the setting and management of the menu and the interface; the second layer is the control layer. It is the control part of the system, which mainly realizes the stretching and bending process control. It consists of eight modules: equipment parameter calibration, process intelligence generation, NC programming, stretching and bending simulation, stretching and bending process control, stretching and bending diagnosis, stretching and bending data processing, and operation assistance. Composition; the third layer is the driver layer, which mainly realizes the communication function with the underlying hardware board. It co...

Abstract

The invention discloses a digital control method for a turntable type stretch bending machine. In order to overcome the shortcomings of the existing technology, such as incomplete function, complex control process, no visibility, and poor reliability, the present invention integrates the functions of process intelligence generation, NC programming, stretch bending process simulation, equipment initialization, process control, and fault diagnosis. Together, the automatic control of the bending process of the rotary stretch bending machine is realized. The invention adopts a modular structure design, which has good openness and portability; adopts an industrial computer (IPC) and a window system, and has a friendly user interface; its stretch bending process simulation and fault diagnosis functions ensure the visibility of the stretch bending process and safety; the method has a high degree of flexibility and automation, is easy to achieve high speed, and has high production efficiency.

Description

Technical field [0001] The invention relates to a digital control method for a rotary table bending machine. Background technique [0002] The well-known stretch-bending machine is used for manufacturing large-size, high-accuracy requirements of shape, and large relative bending radius of variable-curvature extrusion and plate-bending profile bending parts. Its control method is to realize the hybrid control of force, displacement and speed through hydraulic drive, and all control variables are required to be coordinated. [0003] At present, the numerical control method applied to the rotary table bending machine has the following disadvantages: [0004] Generally based on the DOS operating system, the operation interface is not friendly, the programming task is heavy, the workload is large, the debugging and maintenance are difficult, and the function expandability is poor. [0005] Generally constructed closed, dedicated software and hardware architecture, the development cost...
