spring tube bender
spring tube bender is the main equipment for pipe bending processing, and NC technology is the core of pipe bending machine equipment. Improving the NC numerical control equipment control system is of great significance for improving the core competitiveness and market share of China's equipment manufacturing industry. The PAC embedded integrated controller integrating integrated industrial computer and motion control card makes full use of Windows rich software platform and serial port hardware design to develop a set of NC system with rich functions and good performance. The bending process of the pipe bending machine is generally composed of a dozen or so actions such as feeding, transferring, bending, main clamping action, auxiliary clamping action and mandrel action. Common servo actions include: bending (hydraulic pressure, servo), straight line (servo), rotation (servo), up and down (servo, minimum demand), left and right (servo), loading (servo) and unloading (servo).
1. Fanless design (chassis/CPU), no hard disk design (industrial CF card), impact/anti-vibration design (20G/50G/5～500Hz), wide temperature design (-10～50°C), janitor Robust industrial design with dog circuit design and isolated communication interfaces.
2. Open operating system, embedded Microsoft WindowsXP embedded operating system, the system has EnhancedWriteFilter (EWF) function, reducing the operating system damage rate, the optimized system can fully and effectively utilize system resources, so that the startup time <60s, can be completely Also serve as an application developed under Windows XP.
3. The system of NC120 provides remote maintenance software, which can remotely monitor and control the related equipment of the bender control system, including remote monitoring and control, remote screen shots and recording, file uploading and downloading, etc., effectively reducing the trouble of on-site service.
4. Embedded system design, sturdy and durable structure, small size and compact structure, support DIN rail mounting, wall mounting and rack mounting, suitable for industrial automation industry needs.
5. Based on the PC-based platform, the open structure facilitates the expansion of the system structure. Users can arbitrarily realize the increase or decrease of the system structure according to different product series, effectively saving the system's change cost.
6. Controlling the quality of the curved pipe is mainly to control the following three main aspects that require special attention: one is the roundness of the curved pipe, the second is the amount of thinning, and the third is the curvature of the inner surface.
7. The structure of the controlled system, one of which is the human-machine interface, also called HMI; the second is the programmable controller, also called PLC; the third is the servo motor; the fourth is the cylinder; the fifth is the cylinder, etc. . The man-machine interface is a large warehouse that can store hundreds of work skills data to achieve the purpose of interaction between people and machines. The PLC can achieve the function of four-axis positioning, and at the same time, it can achieve the function of controlling two sets of interpolation, which is the way to achieve extremely complicated work requirements.
8. The entire control system can be roughly divided into three parts, one is the mechanical part, the other is the hydraulic part, and the third is the electrical control part. If the pipe bending machine is regarded as a living person, then the electrical control part will be the head of the bending machine. The head will command the hydraulic and mechanical parts according to the pre-programmed procedures and the settings before the bending. Complete the work of bending. The hydraulic part can be regarded as its neural network and blood circulation system, which drives the mechanical part under the control of the electric control part; the mechanical part is the torso of the bender and two arms. To complete the specific bending action.
