Electrical control system of steel plate edge milling machine

Abstract

The invention discloses an electrical control system of a steel plate edge milling machine, and the system comprises a PLC (programmable logic controller), a touch screen, an operating console, a movable trolley control system, a clamping trolley control system, a hydraulic control system, a lubrication control system, a milling head position and speed control system, a steel plate centering and width measuring system and a profiling mechanism automatic following system. The touch screen is connected with the PLC through a Profibus-DP bus. The steel plate centering and width measuring system comprises a southern centering terminal box, a northern centering terminal box, a southern width measuring bus displacement sensor, a northern width measuring bus displacement sensor, a south-west centering bus displacement sensor, a south-east centering bus displacement sensor, a north-west centering bus displacement sensor and a north-east centering bus displacement sensor, and the profiling mechanism automatic following system comprises a southern vertical profiling roller bus encoder, a northern vertical profiling roller bus encoder, a southern horizontal profiling roller bus encoder and a northern horizontal profiling roller bus encoder. The electrical control system of the steel plate edge milling machine has a reasonable design, advanced technology, high processing accuracy of control equipment, high processing quality, high production efficiency and low failure rate, the cost and energy can be saved, the use effects are good, and the promotion and application can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of automatic control of steel plate processing, in particular to an electrical control system of a steel plate edge milling machine. Background technique [0002] The height and precision of the down groove and the height and precision of the blunt edge after edge milling of the steel plate for the large-diameter longitudinal submerged arc welded pipe are very important to the welding quality of the steel pipe. If the height and accuracy of the down groove and the height and accuracy of the blunt edge after milling of the steel plate cannot meet the requirements of the welding process, other problems such as non-penetration and breakdown will occur in the welding quality during subsequent welding. The traditional processing method for the edge of the steel plate is to fix the steel plate, and manually operate the milling machine to move along the longitudinal edge of the steel plate to perform the milling op...
