High-frequency welded pipe shape adjusting and self-diagnosing device based on encoders

Abstract

The invention discloses a high-frequency welded pipe shape adjusting and self-diagnosing device based on encoders. A PC upper computer is used for setting instructions and all parameters, and a PLC processes signals into switch variable signals and transmits the switch variable signals to an output module; the output module controls the starting of a hydraulic motor by controlling an electromagnetic valve; each hydraulic motor is provided with one SICK digital encoder, and the SICK digital encoders collect position signals of the hydraulic motors; an encoder communication module processes thereceived signals of the SICK digital encoders; and then the signals are processed by the PLC and displayed on the PC upper computer. The numerical value of the on-site encoder can be read to achieve rapid and accurate shape adjustment, meanwhile, the specific position data of all encoders in the production process can be monitored in real time, the faults of the on-site encoders can be diagnosed at any time, and the self-diagnosis of an encoder system is realized.

Description

technical field [0001] The invention belongs to the field of steel pipe production, and in particular relates to a high-frequency welded pipe adjustment and diagnosis device. Background technique [0002] At present, for most high-frequency welded pipe manufacturing enterprises, there is no simple, safe, visual, intuitive and effective complete numerical method to quickly and accurately complete the adjustment of steel pipes, and can dynamically monitor the position of equipment during production with digital display status State, usually the manual static method is commonly used to adjust the type, relying on the steel ruler to measure, manually read the value, repeatedly compare the gap parameters required by the process, and constantly move the equipment parts to complete the adjustment work, which is not accurate enough, resulting in large errors and adjustment. The process is cumbersome and takes a long time, resulting in a waste of time. At the same time, it is impossi...

[0002] At present, for most high-frequency welded pipe manufacturing enterprises, there is no simple, safe, visual, intuitive and effective complete numerical method to quickly and accurately complete the adjustment of steel pipes, and can dynamically monitor the position of equipment during production with digital display status State, usually the manual static method is commonly used to adjust the type, relying on the steel ruler to measure, manually read the value, repeatedly compare the gap parameters required by the process, and constantly move the equipment parts to complete the adjustment work, which is not accurate enough, resulting in large errors and adjustment. The process is cumbersome and takes a long time, resulting in a waste of time. At the same time, it is impossible to observe the position and status of equipment components in real time during production, and it is impossible to correct deviations in time, to ensure the quality of steel pipe forming, and to meet the requirements of rapid and precise adjustment

The work consumes a lot of manpower, the labor intensity is high, and it cannot meet the production safety guarantee, so that the equipment runs with inaccurate molding problems during the start-up process, resulting in unstable molding and fluctuations after the production line is started, which increases the number of search problems. Difficulty and processing solve the process time, affect the production schedule, and cause production cost and time waste
