Automatic Loading-Equipped Rigid Type Stranding Machine: Essential for Cable Making
1. Application
This machine is mainly used for the non-torsion stranding of large-cross-section and long-length steel-cored aluminum strands (ACSR) and aluminum alloy conductors. It can also be applied to the non-torsion stranding and compacting of copper conductors with round, special-shaped, and sector-shaped core.
2. Main component
2.1 Φ630 Pay-off stand
2.2 #type wire guiding stand
2.3 6B,12B strander
2.4 Wire assemble die & compacting device
2.5 Meter counter(Mechanical, Electronic)
2.6 Φ 1600 strong double capstan
2.7 Φ 1800 column type take-up with traversing
2.8 Electric control system

3. Features
3.1 The whole machine is driven by the independent motor, and each section of the cage and capstan are driven by a separate permanent magnet synchronous servo motor. The cage is driven to rotate through a dedicated gearbox, which simplifies the structure compared to traditional ground shaft linkage driven rigid type strander and makes equipment maintenance more convenient.
3.2 The control of the whole machine adopts Inovance series PLC, and various production process parameters are set through the touch screen. Each section of the cage and capstan are driven by a Jiangsu Zhima servo motor, and the motor driver is a frequency converter device. To ensure transmission accuracy, the transmission motor adopts a grating encoder feedback, and the whole machine adopts a bus communication method to ensure signal transmission accuracy. In actual production, users set the process parameters such as the pitch of each section of the cage and the speed of the production line on the touch screen according to the required cable specifications. When starting up, the speed of each transmission part is automatically calculated by PLC to ensure the synchronization of the whole machine and the accuracy of the twisted wire pitch, and to achieve stepless speed regulation of the whole machine. The electronic control system has advanced technology, convenient operation, and reliable operation.
3.3 The pulse principle is used to detect wire breakage, which can accurately determine the wire breakage signal of any bobbin in each section of the cage, ensuring detection accuracy. Through the display on the touch screen, the operator can quickly solve the problem and start the next start up.
3.4 The machine uses Inovance programmable controller and field bus to unified command and coordinate the working status of all parts of the machine, and uses a frequency converter to control the starting and operation of the AC motor. Inovance touch screen is used to set and display various process parameters. The electronic control system is technologically advanced, easy to operate and reliable in operation.
