Problems solved by technology

[0004] However, the existing automatic closing method only controls the position of the tape tail, and cannot take into account the position of the jaw (lead) at the same time, so it cannot meet the closing requirements of the jaw coiling unit

Embodiment 1

[0047] This embodiment provides an automatic finishing system for a strip jaw coiling unit, which includes a reel, a coiling pressure roller, and a slitting shear 1 arranged in sequence along the horizontal direction. The jaw is equipped with a control system and a phase detection switch 5 of the jaw. The phase detection switch 5 of the jaw is fixed at the jaw. The phase detection switch 5 of the jaw, the drum motor, and the take-up roller Both the solenoid valve and the slitting shear 1 motor are connected with the electrical signal of the control system;

[0048]The control system includes an operation module, a parameter input module, a signal input module and a signal output module, and the operation module is used for inputting each parameter value according to the parameter input module and the jaw phase β detected by the jaw phase detection switch 5 1 Calculate the automatic closing angle α and the ideal cutting position β 2 , and then through the signal output module ...

Embodiment 2

[0052] On the basis of Embodiment 1, this embodiment provides an automatic finishing system for strip jaw coiling units, the jaw phase detection switch 5 is a reflective photoelectric switch, and the reflective photoelectric switch includes a photoelectric switch and A reflection plate, the photoelectric switch is installed on the coiler body, and the reflection plate is installed at the jaw.

[0053] In this embodiment, the jaw phase detection switch 5 is a photoelectric switch for detecting the jaw phase β 1 , Take the strip coiling direction as positive.

Embodiment 3

[0055] On the basis of Embodiment 1, this embodiment provides an automatic finishing system for the strip nip coiling unit. The parameters input through the parameter input module include the distance between the cutting edge of the slitting shear 1 and the center of the exit turning roller. distance L 1 , the radius r of the exit turning roller, the distance B between the center of the exit turning roller and the center of the reel of the coiler, the phase γ of the coil unloading push plate 6 of the coiler, and the phase angle of the tape tail after the automatic tailing is completed α 3 .

[0056] For each coiling unit, after the on-site layout and assembly are completed, there are many parameters that are fixed values. Input these parameters in advance, and calculate the automatic closing angle α and the ideal cutting position β through the calculation module 2 .

Abstract

The invention provides an automatic finishing system and method for a strip jaw coiling unit. The system comprises a coiling block, a coiling compression roller and a slitting shear, which are sequentially arranged along the horizontal direction; an outlet turning roller is arranged at one side of the coiling block; a jaw is arranged on the coiling block; the automatic finishing system further comprises a control system and a jaw phase detection switch; the jaw phase detection switch is fixedly arranged at the jaw; and the jaw phase detection switch, a coiling block motor, a coiling compression roller control electromagnetic valve and a slitting shear control electromagnetic valve all are connected with the control system via an electric signal. According to the system and the method, the defect that only the position of the strip tail can be controlled in a traditional automatic finishing method is overcome, it can be guaranteed that the strip head and the strip tail are stopped at the target positions during automatic finishing of the jaw coiling unit, and coil stripping accidents of the jaw coiling unit are reduced, so that the coil core quality of a finished coil, the production efficiency and the automation degree of the unit are improved.

Description

technical field [0001] The invention belongs to the technical field of finishing processing of metal strips, and in particular relates to an automatic finishing system and method of a strip jaw coiling unit. Background technique [0002] In the metallurgical industry, the strip rolled by the cold rolling mill must be finished and processed in order to obtain high-quality qualified products. The finishing unit mainly carries out recoiling, trimming, slitting and other processes. The typical production process of the strip finishing unit is as follows: strip threading → coiling assistance → coiling → finishing → coil unloading. Common roll aid methods include roll aid roll aid and jaw roll aid. [0003] For the unit that uses jaws to assist coiling, the lead head is easy to scratch the jaws when unloading the coil directly, resulting in loose inner ring of the material coil, tower-shaped defects, and even coil unloading failure, which seriously affects product quality and pr...
