Rotation feed rate and cutting torch feed rate of automatic fiber cutting machine manufacturers
Because the full-automatic fiber cutting manufacturers of the whole Taiwan group cut the formed steel pipe, there is no defect such as cracks caused by the first cutting and then crimping; the cutting torch is fed uniformly under the control of the CNC system, and the rail error is greatly reduced. It provides conditions for improving the welding quality and efficiency of the joints of the two pipes. So far, the relationship between the rotation feed rate of the automatic fiber cutting steel pipe and the cutting torch, the rotation speed of the steel pipe and the feed rate of the cutting torch has been established for the group of cutting steel pipes. In this way, under the control of the CNC system, the rotation of the steel pipe and the feed of the cutting torch are linked to realize the cutting of the automatic fiber cutting of the steel tube group, and the cutting of the non-cylindrical tube group of the automatic fiber cutting. The group of cutting round tubes is fully automatic optical fiber cutting. The cutting torch feeds along the X direction. Once the distance between the cutting torch and the tube wall is adjusted, it is fixed until the cutting is completed. The structure of the large-diameter steel pipe group automatic light-cutting numerical control cutting machine is composed of a numerical control device, a steel pipe rotating feed and support, a cutting torch feed actuator and a corresponding control circuit. The axis of the feed screw and the axis of the supporting steel pipe are in the same horizontal plane. In order to meet the needs of cutting the steel pipe and adapt to the change of the diameter of the steel pipe, a tensioning and closing wheel is set under the steel pipe. The distance between the two ends of the steel pipe mounted on the dovetail groove can be adjusted to adapt to the change of the length of the steel pipe. The steel pipe adopts synchronous telescopic clamping device.
When the steel pipe of the whole Taiwan group is fully automatic fiber cutting manufacturer, the steel pipe is obliquely crossed. The oblique angle of the cutting torch relative to the axis of the steel pipe needs to be adjusted. For this purpose, an angle index plate is provided to indicate the inclination angle of the cutting torch. Performance parameters Cutting steel pipe diameter: 0.8~1.5m cutting steel pipe length: 12m steel pipe rotation feed motor type: large inertia DC servo motor large inertia DC motor power: 22kW, design a digital controller, digital controller control The algorithm adopts continuous system discretization design and discrete domain design methods. The digital phase shift signal outputted by the digital controller in the microcomputer is sent to the trigger control link. The thyristor trigger adopts a digital trigger type, which eliminates D/A conversion. Phase shift and pulse distribution are based on the synchronization signal, and the software controls the CPU and the interface circuit to complete the transmission of pulses to the power amplifier circuit. Through the interface circuit 5, relevant data and fault display and alarms can be performed in real time. The speed control system controlled by the microcomputer, the speed control system controlled by the microcomputer, the cutting torch feed control realizes that the feed of the cutting torch along the X and Z axis is driven by a stepping motor. The ring distributor of the stepping motor drive power selects the software distribution mode. The hardware ring distributor has a better response speed, and has the characteristics of intuitiveness and convenient maintenance. The software loop can simplify the hardware structure and has flexible adaptability. However, limited by the computing speed of the microcomputer, it is sometimes difficult to meet the requirements of high-speed real-time control. Since the response speed required by the cutting torch feed is not high, software loop analysis is adopted. Drive circuit Tianzheng laboratory is one of the domestic low-voltage electrical industry laboratories in line with international standards. On January 26, the Tianzheng Group laboratory was reviewed by the China Laboratory Accreditation Committee in accordance with the internationally accepted ISO/IEC rules and became a domestic low-voltage electric hair dryer. Industries, including international ABB, Siemens, Schneider, etc., among domestic enterprises in my country, are in line with international standards. The laboratory established by Tianzheng invested more than 10 million yuan in 1999. After more than two years of continuous improvement, all aspects of the work have been scaled and standardized. The cost-effectiveness considered when selecting the CNC system for 10 groups of all automatic fiber cutting manufacturers.
