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, and the phase detection switch 5 of the jaw, the reel motor, and the take-up roller are controlled. 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 s...

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 of a strip jaw coiling unit. The system includes a reel, a coiling pressure roller and a slitting shear arranged in sequence along the horizontal direction, and an outlet turning roller is arranged on one side of the reel. The reel is equipped with jaws, and also includes a control system and a jaw phase detection switch. The jaw phase detection switch is fixed at the jaws. Both the valve and the slitting and shearing control solenoid valve are connected with the electric signal of the control system. The invention overcomes the defect that the traditional automatic tailing method can only control the position of the tape tail, so that the jaw coiling unit can ensure that both the tape head and the tape tail stop at the target position during automatic tailing, and reduces the unloading accident of the jaw coiling unit Occurs, thereby improving the quality of the finished roll core, production efficiency and unit automation.

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...
