[0027] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0028] Embodiment One

[0029] To solve the technical problem that the existing working roller gap zero position calibration scheme requires the use of a calibration block with high manufacturing precision or a cumbersome calculation process, and cannot be applied to a large industrial production environment, the present application provides a working roller gap zero position calibration method for a straightening and leveling machine as shown in Figure 1 The calibration method comprises the following steps:

[0030] S101, a steel wire is placed on the driving side and the operating side of the working surface of the straightening and leveling machine in close contact with the working surface, and the steel wire is straightened;

[0031] S102, adjust the stretch leveler, so that the first lower bending roller 3, the second lower bending roller 7 and the straightening roller 9 of the stretch leveler are tangent to the steel wire at the same time, and the obtained tangent point is taken as the working roller gap zero position.

[0032] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0033] First of all, the term "and / or" appearing in this paper is only to describe the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0034] The present embodiment provides a method for calibrating the working roller gap zero position of a stretch leveler, which is applied to the stretch leveler.

[0035] As shown in the accompanying Figure 2 The stretch leveler includes an entry side deflector roller 1, an exit side first deflector roller 8 and an exit side second deflector roller 10 arranged in sequence above the working surface of the stretch leveler. A first bending roller and a second bending roller are arranged between the entry side deflector roller 1 and the exit side first deflector roller 8, wherein the first bending roller includes a first upper bending roller 2 and a first lower bending roller 3 arranged symmetrically along the working surface; and the second bending roller includes a second upper bending roller 6 and a second lower bending roller 7 arranged symmetrically along the working surface. A straightening roller 9 is arranged below the working surface between the exit side first deflector roller 8 and the exit side second deflector roller 10. The side on which the staff stands in front of the stretch leveler is the operation side of the stretch leveler, and the side opposite to the staff is the transmission side of the stretch leveler. The exit side first deflector roller 8, the exit side second deflector roller 10 and the straightening roller 9 cooperate with each other to straighten the strip steel. The strip steel repeatedly bends under the action of front and rear tension, the center layer deviates and deforms, thereby obtaining a certain elongation, and finally achieving the purposes of breaking scales and improving the strip shape.

[0036] In order to calibrate the working roller gap zero position, first, step S101 is performed, that is, a steel wire is placed on the transmission side and the operation side of the working surface of the stretch leveler, and the steel wire is straightened.

[0037] Specifically, the first upper bending roller 2 and the second upper bending roller 6 are quickly opened; the operation side steel wire 4 is connected between the entry side deflector roller 1 and the exit side second deflector roller 10 of the stretch leveler on the operation side; and the transmission side steel wire 5 is connected between the entry side deflector roller 1 and the exit side second deflector roller 10 of the stretch leveler on the transmission side. The operation side steel wire 4 and the transmission side steel wire 5 are not connected.

[0038] The operation side steel wire 4 and the transmission side steel wire 5 are both 2m-3.5m, so that the length of the steel wire can penetrate through the whole rack of the straightening and leveling machine. In order to improve the accuracy of the calibration, the operation side steel wire 4 and the transmission side steel wire 5 used are straight. In the embodiment, the operation side steel wire 4 and the transmission side steel wire 5 used are both 2m, and it should be noted that the steel wire actually used can be any value in the range of 2m-3.5m, which is not limited herein.

[0039] In order to improve the accuracy of the calibration, a lead weight is hung below the operation side steel wire 4 and the transmission side steel wire 5 respectively, so as to improve the flatness of the operation side steel wire 4 and the transmission side steel wire 5 during the straightening process.

[0040] Then, the operation side steel wire 4 and the transmission side steel wire 5 are straightened on the operation side and the transmission side, so that the operation side steel wire 4 and the transmission side steel wire 5 are both in a horizontal state.

[0041] Then, step S102 is performed, and the straightening and leveling machine is adjusted, so that the first lower bending roller 3, the second lower bending roller 7 and the straightening roller 9 of the straightening and leveling machine are tangent to the steel wire at the same time, and the obtained tangent point is taken as the working roller gap zero position.

[0042] Specifically, first, the first lower bending roller 3, the second lower bending roller 7 and the straightening roller 9 are respectively operated to rise individually, and when the first lower bending roller 3 or the second lower bending roller 7 is tangent to the operation side steel wire 4 or the transmission side steel wire 5, the rising operation is stopped, the relative positions of the lower roller surfaces of the straightening and leveling machine on the operation side and the transmission side are observed, and the relative positions are measured by using a feeler gauge. When the horizontal deviation of the first lower bending roller 3 or the second lower bending roller 7 on the operation side and the transmission side is greater than 1.5mm, the coupling of the working roller is disconnected, and the horizontal deviation of the side with greater deviation is adjusted, so that the horizontal deviation of the first lower bending roller 3 on the operation side and the transmission side is not higher than 1.5mm, and the horizontal deviation of the second lower bending roller 7 on the operation side and the transmission side is not higher than 1.5mm. Thus, the horizontal deviation of the first lower bending roller 3 and the second lower bending roller 7 is controlled within the allowable range of the deviation threshold, so as to prevent the abnormal plate shape caused by the horizontal deviation after the straightening and leveling, and to improve the accuracy of the working roller gap zero position calibration of the straightening and leveling machine and the effectiveness of the plate shape control.

[0043] Then click the upper bending roll of the straightening and leveling machine to close, so that the first upper bending roll 2 and the second upper bending roll 6 are in the normal working position, and then click the work roll gap of the straightening and leveling machine to slightly open, so that the first and second lower bending rolls 7 and the straightening roll 9 are lowered to a state of just separating from the first lower bending roll 3, the second lower bending roll 7 and the straightening roll 9, at this time, the first lower bending roll 3 is compared again with the steel wire, so that the horizontal deviation of the first lower bending roll 3 on the operating side and the driving side is not higher than 1.5 mm, and the horizontal deviation of the second lower bending roll 7 on the operating side and the driving side is not higher than 1.5 mm. Thus, in the normal working state, the horizontal deviation of the first upper bending roll 2 and the second upper bending roll 6 is controlled within the deviation threshold allowable range.

[0044] After the adjustment of the horizontal degree of the work roll is completed, the upper bending roll of the straightening and leveling machine is quickly opened, and the first lower bending roll 3, the second lower bending roll 7 and the straightening roll 9 are respectively lifted again to the tangent point position of the steel wire. Since the work roll of the straightening and leveling machine is staggered arranged, the mechanical zero position is the position where the lower surface of the upper bending roll of the straightening and leveling machine is tangent to the upper surface of the lower bending roll of the straightening and leveling machine, at this time, the upper and lower bending rolls are just in the same horizontal plane without relative coincidence, so this position is the zero position of the staggered arranged work roll, that is, the mechanical zero position of the straightening and leveling machine. The tangent points are marked one by one on the mechanical scale of the straightening and leveling machine, so as to ensure the detection accuracy of the zero position of the work roll gap.

[0045] The calibration method provided in the application further includes that after the work roll gap calibration of the straightening and leveling machine is completed, a certain value of the bending roll insertion amount is set, after the first lower bending roll 3, the second lower bending roll 7 and the straightening roll 9 are moved to the corresponding zero positions, the data displayed by the total station instrument and the encoder are checked respectively, if the actual gap of the first lower bending roll 3, the second lower bending roll 7 and the straightening roll 9 and the set deviation is controlled within ±2.0 mm and below, it indicates that the production process requirements are met, and then the normal production is restored; if the actual gap of the first lower bending roll 3, the second lower bending roll 7 and the straightening roll 9 and the set deviation exceeds ±2.0 mm, it indicates that the production process requirements are not met, and the calibration is re-performed.

[0046] The work roll gap zero position calibration method provided in the embodiment is simple to operate and easy to control, without the need of using calibration blocks with high manufacturing precision or complicated calculation processes, so that the technical effect of calibrating the work roll gap zero position in a simple way is realized. After the mechanical zero position of the method is checked by the total station instrument and the like, the control precision is high, the work roll gap zero position calibration standard is met, and the normal production requirements can be met.

[0047] Through the above-mentioned mode, the high-standard plate shape control requirements and the scale breaking effect can be ensured, so as to realize the continuous development and expansion of high-value-added products, improve the market competitiveness of the products, and have good application value.
