Project Background
Sichen Machinery has determined the control system design for the production line from the forming process, quality assurance process, and workshop overall network aspects based on the production process of spiral welded pipes.
By combining these three parts, the digital automation of the entire spiral welded pipe production line has been realized, realizing the functions of optimized control, automatic tracking, data management, and network monitoring of the production process.
Project Introduction
Based on the problems existing in the traditional spiral welded pipe production process for twenty years, a software and hardware integrated automatic optimization cutting system for steel pipes has been designed. Two PLCs respectively collect the encoder pulses placed at different workstations, exchange production data and control the production process in real time through wireless Ethernet, and realize automatic optimization cutting of spiral welded pipes. The automation design of key links in the spiral welded pipe production line has been realized.
1) Adjust the roller adjustment amount △H to correct the pipe circumference deviation △L;
2) Adjust the rear bridge drive oil cylinder adjustment amount △Y to correct the weld gap deviation △G;
3) Compensate the auxiliary roller compensation adjustment amount △HG caused by the swing of the rear bridge to change the pipe circumference. After this set of pipe circumference and weld gap automatic control device is installed on the unit, the pipe circumference deviation can be controlled within ±2mm; the weld gap deviation can be controlled within ±0.3mm. The automated control of the forming process can significantly improve product quality and avoid steel pipe quality problems caused by insufficient operator experience and operational errors.
Project Value
Due to the thick thickness of the steel plate, it is difficult to form it in one time, and there are many variables in the hot extrusion process. Si Chen Machinery has developed special equipment that meets the extrusion process of different products and achieves automatic pressing and forming multiple times.
This equipment includes product conveying roller conveyors, medium-frequency local and overall heating, press equipment, and a cooling circulation system.
Improve Production Efficiency
The fully automatic spiral forming machine can effectively avoid errors and insufficient experience in manual operation that lead to unstable steel pipe quality, as well as restrictions on the production of high-grade steel pipes.
Stable Production, Increased Productivity
Digital intervention comprehensively monitors various data in the forming process, can timely adjust various problems that occur in the forming process, stabilizes the forming process, plays a decisive role in the manufacturing of high-grade spiral steel pipes, and realizes the optimized control, automatic tracking, and data management of the forming process. functions.
