Description

Technical Field

[0001] The present invention relates to the technical field of high-speed wire rolling mills, and in particular to an auxiliary equipment operation simulation system and method. Background Art

[0002] At present, most of the Φ6-Φ12 round wires produced domestically are rolled using high-speed wire rolling mills. After rolling, a vertical roller bed conveying mechanism is used as a new type of coiling method to perform PF wire coiling on the rolled wires.

[0003] The basic function of the vertical roller bed conveying mechanism is: conveying from the cooling roller to the collection drum, and falling onto the closed pallet through the nose cone. When the wire coil rotating mechanism rotates normally and is in the position of receiving the coil core frame, the pallet lifting mechanism lifts the core frame up, and after reaching the upper limit, it just supports the nose cone in the collection drum, and then gradually descends to place the wire coil on the coil core frame. After the wire coil is received, the lifting device descends to the lower limit, and the claws open accordingly. After the coil core frame conveying roller bed detects the presence of the coil core frame, it rotates to convey the coil core frame to the next roller bed. During the whole process, the equipment adopts interlocking control to convey the coil core frame to the rotating mechanism. When the coil core frame stops, it rotates 90° in the opposite direction and docks with the lower conveying roller bed. The coil core frame conveying roller bed behind the running direction and the conveying roller bed on the rotating mechanism are started at the same time to convey the coil core frame to the lower conveying roller bed. This repeated movement completes the conveying function.

[0004] However, the main control system of the high-speed wire rolling mill mentioned above does not have an operation simulation control system for the high-speed wire coiling area equipment. Each time the equipment is tested, the equipment interlocking control system must be disconnected and each unit must be started manually. Ground operators must confirm whether the equipment is operating normally. A lot of time is required to confirm the status of the equipment during the entire process. At the same time, manual confirmation of each unit may result in omissions and safety risks. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary equipment operation simulation system and method, which solves the problem that the main control system of the existing high-speed wire rolling mill does not have an operation simulation control system for the high-speed wire coiling area equipment. Each time the equipment is tested, the equipment interlocking control system must be disconnected and manually started one by one. Ground operators must confirm whether the equipment is operating normally. During the entire process, a lot of time is required to confirm the status of the equipment.

During operation, the operation of the corresponding elements of the vertical roller bed conveying mechanism 108 is monitored in real time by the external sensor 109, and the monitoring results are transmitted to the process monitoring device 104 via the PLC control device 103 for display, so that real-time monitoring of the simulation process can be achieved. By setting an operation simulation control system in the high-speed wire coiling area, the technical problems of omissions and safety risks caused by the fact that the high-speed wire PF line production equipment has no simulation operation function and needs to be manually confirmed by each device are solved.
