[0004] When existing rolling mill equipment is rolling plates, in order to cope with the processing requirements of plates with different cross-sectional widths, a limiting structure is usually used at the end of the rolling mill to achieve the overall limiting of the plates. However, in the actual rolling process, since the rolling line of the plates is long, it is necessary to design a limiting structure in the middle position of the rolling line to ensure that the plates always maintain an effective limiting state during the rolling process to cope with various forms of rolling requirements. Summary of the invention

[0034] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-2 An intelligent rolling mill for fireproof rolling door blade profile is shown, comprising a rolling mill body 1 for rolling a plate 001 with a plurality of rollers installed inside, a rotating rod 4 is rotatably connected to the inner side of one end of the rolling mill body 1, a surface of the rotating rod 4 is provided with symmetrically arranged screw areas 41, and the thread directions of the surfaces of the two screw areas 41 are arranged in mirror image, a movable block 5 is connected to the surface of the screw area 41 through a threaded sleeve, and the surfaces of the two movable blocks 5 facing away from each other are both installed with an extended slide rod 2 with an L-shaped cross section, a plurality of fixed rods 6 are fixedly installed on the surface of the extended slide rod 2, and the fixed rod 6 slides through the side wall of the rolling mill body 1, and the tail end of the fixed rod 6 is connected to an adaptive limit unit 3 located between the two rollers;

[0037] Figure 4 It is shown that the adaptive limit unit 3 includes an upper block 31 whose surface is fixedly connected to the tail end of the fixed rod 6, the surface of the upper block 31 is connected to a servo motor 32 through a mounting piece, the lower part of the upper block 31 is connected to a lower block 33 through an axis rod, and the output end of the servo motor 32 is connected to the axis rod, an adjustment groove is provided inside the lower block 33, and a clamping group is slidably connected inside the adjustment groove, the clamping group includes two limit clamps 34, and the sides of the two limit clamps 34 are connected to sliders, and two adjacent sliders are connected by a fine-tuning screw 37, an electromagnetic adjustment block 35 is installed on the bottom wall of the adjustment groove, and a magnetic suction sheet 36 is connected to the bottom end of the lower limit clamp 34.

[0038] Specifically, when rolling the fireproof rolling door blade, the plate 001 needs to be placed on the surface of the rotating rod 4, and then the driving motor is started to drive the movable blocks 5 on the surface of the screw area 41 to approach each other. Since the movable blocks 5 are symmetrically arranged and move at the same speed, even if the plate 001 is not placed in the center of the rotating rod 4 in the initial state, the plate 001 can be placed in the center of the rotating rod 4 under the pressure of the movable blocks 5 approaching each other, thereby realizing the automatic centering operation.

[0039] Figure 3It is shown that the movable block 5 and the surfaces of the lower and upper blocks 33 in the vertical state that are close to each other are on the same straight line, and the cross-sectional width value of the two limit clamps 34 is greater than the thickness value of the lower block 33. As the movable blocks 5 approach each other, the adaptive limit unit 3 also approaches synchronously and is in the same limit width state as the plate 001. In the subsequent rolling process, the side of the plate 001 can be effectively limited, and the installation of a limit ring on the surface of the roller can be avoided. Because the gap between the upper and lower rollers is small, if the limit ring wants to limit the plate 001 between the rollers, the gap between the rollers needs to be filled, which will cause friction between the roller and the surface of the limit ring when the roller rotates, which is easy to cause damage to the limit ring;

[0040] The gap between the two limit clamps 34 can be adjusted by the fine-tuning screw 37 to meet the rolling thickness requirement of the plate 001, and the electromagnetic force between the electromagnetic adjustment block 35 and the magnetic suction sheet 36 can be used to attract or repel each other, so as to adjust the position of the limit clamp 34 in the adjustment slot to adapt to clamping and limiting operations at different heights;

[0041] When the plate 001 is flat, the lower block 33 is in a vertical position, and the plate 001 passes horizontally between the limiting clamps 34 to achieve the limiting process (such as Figure 5 shown);

[0042] When the plate 001 has folded edges on both sides, the lower vertical block 33 is switched to a horizontal state under the action of the servo motor 32, and the horizontal position of the limit clamp 34 in the adjustment groove is adjusted according to the length of the folded edge, so that the limit clamp 34 after switching the state can smoothly realize the clamping limit of the folded edge (such as Figure 6 shown);

[0043] When the plate 001 is rolled asymmetrically on both sides, the servo motor 32 can be used to drive the lower block 33 to tilt at a certain angle and fit on a folded edge of one side of the plate 001, thereby achieving an effective restraining effect (such as Figure 7 as shown).

[0044] The fine-tuning screw rod 37 comprises a screw rod, the outer thread of the screw rod is sleeved with a sleeve rod with an inner thread.

[0045] Specifically, the screw rod and the sleeve rod are rotatably connected to the slider respectively, and the overall length of the screw rod and the sleeve rod can be adjusted by rotating the screw rod forward and backward, thereby achieving the adjustment purpose of the fine-tuning screw rod 37.

[0046] A driving motor is installed on the surface of the rolling mill body 1 , and an output end of the driving motor is connected to one end of the rotating rod 4 .

[0047] Specifically, by driving the rotating rod 4 to rotate by a driving motor, the mutual approach distance of the movable blocks 5 on the surface of the rotating rod 4 can be adjusted to adapt to the clamping and limiting operation of the plates 001 of different widths.

[0048] It also includes a rolling control system, which includes a processor installed on the rolling mill body 1, and the processor is connected to an execution input module, an adjustment drive module and a limit feedback module. The execution input module includes a display installed on the rolling mill body 1, which is used to input the cross-sectional width and rolling parameters of the plate 001 to be rolled. The adjustment drive module is connected to the drive motor and the electromagnetic adjustment block 35 signal, and is used to adjust the distance between the two movable blocks 5 and the horizontal position of the limit clamp 34 in the adjustment groove. The limit feedback module includes a photoelectric sensor installed on the surface of the lower block 33, which is used to feedback the state of the plate 001 when passing through the surface of the lower block 33.

[0049] The photoelectric sensors are distributed on both sides of the adjustment slot, and there are multiple photoelectric sensors.

[0050] Specifically, by executing the input module, the rolling requirements of the plate 001 can be input to the rolling mill body 1, so that the rolling mill body 1 can perform rolling processing of different shapes and sizes according to the requirements, and provide a corresponding reference basis for the opening and closing of the driving motor in accordance with the cross-sectional width of the plate 001;

[0051] Through the multiple photoelectric sensors installed on the two side surfaces of the lower upright block 33 in the limit feedback module, the plate 001 can be effectively monitored when passing through the limit clamp block 34 to determine whether the plate 001 is in a linear limit conveying state.

[0052] The second implementation method:

[0053] Fig. 9 The replacement structure of the fixed rod 6 is shown to be an electric extension rod 7, and the two electric extension rods 7 on the same horizontal line are electrically connected, and the surfaces of the two lower blocks 33 closest to the movable block 5 along the vertical axis are installed with pressure sensors, and the electric extension rods 7 and the servo motor 32 are all connected to the limit feedback module signal.

[0054] Different from the first embodiment, in this embodiment, when the plate 001 is clamped by the movable block 5 to the position of the first lower block 33, due to the lack of corresponding guide and limit devices, there will be a small error (such as Figure 8 As shown in the figure), subsequent continued conveying will make it difficult for the rolled end of the plate 001 to stably reach the limiting clamp block 34 in the lower vertical block 33 to receive the limiting constraint treatment.

[0055] Specifically, when the rolled end (plate 001 is a flat plate) is misaligned and causes the rolled end to reach the surface of the first lower block 33, one side of the rolled end will exert an extrusion effect on the surface of one of the lower blocks 33, and the surface of the other lower block 33 at the same horizontal position does not contact the rolled end of the plate 001 or the contact force is significantly smaller than the extrusion force on the surface of one of the lower blocks 33. At this time, it is necessary to start the electric extension rod 7 on the side where the lower block 33 on the side with stronger extrusion is located to retract it and then reset it to its original state. The rolled end with a small amount of misalignment can be reset (such as Fig.10 As shown), if the plate 001 is folded on both sides, the electric extension rod 7 on the side with greater force can be retracted first, and the other electric extension rod 7 can be extended, and the corresponding servo motor 32 can be used to drive the lower block 33 to rotate more than 90 degrees, so that the limit clamp 34 is in a tilted state, and then the servo motor 32 is restored to the state where the lower block 33 is rotated 90 degrees, the rolled end fold is clamped and limited, and the two electric extension rods 7 are subsequently restored to their original state (as shown in FIG. Fig.11 As shown), it plays a linear traction effect in the process of the rolling end transitioning from the position of the movable block 5 to the first adaptive limit unit 3;

[0056] The plate 001 is a rolled design with flat plates on both sides and a depression in the middle. At this time, the limit width value between the movable blocks 5 is greater than the limit width value between the lower upright blocks 33. At this time, it can be adjusted in conjunction with the electric extension rod 7.

[0057] The second implementation method:

[0058] Fig.13 The replacement structure of the slider is shown to be a magnetic frame 8, which includes a round rod, the surface of which is sleeved with a magnetic ring with a diameter greater than the height value of the slider, and the magnetic ring is slidably connected to the inside of the adjustment groove, and the tail end of the round rod is rotationally connected to the surface of the limit clamp 34, the inside of the limit clamp 34 is connected to an inclination sensor, and the sides of the two limit clamps 34 are fixedly connected with a constraint 9, and the constraint 9 is located inside the adjustment groove.

[0059] The constraint member 9 is an elastic tube with built-in electrorheological fluid, and the constraint member 9 is connected to the tilt sensor signal. The elastic tube is located above the magnetic ring, and the surface of the elastic tube is coated with a magnetic layer that repels the magnetic ring.

[0060] Different from the first embodiment, the present embodiment mainly aims to improve the phenomenon that the folding length is too long, resulting in the folding height in the vertical state overlapping with the lower upright block 33 in the horizontal state, thereby affecting the limiting effect.

[0061] Specifically, when the folding length is greater than the vertical gap between the surface of the plate 001 and the bottom surface of the lower upright block 33 in the horizontal state, the servo motor 32 is required to continue to tilt the lower upright block 33 upward. At this time, the limit clamping block 34 in the first embodiment is in an inclined state, and it is difficult to effectively limit and clamp the folding edge in the vertical state (such as Fig.12 shown);

[0062] In the present embodiment, a magnetic ring is used to replace the magnetic sheet 36. Since the surface of the limit clamp block 34 is rotatably connected to the tail end of the round rod, after the lower block 33 is tilted, the adjustment slot is synchronously in a tilted state, but the limit clamp block 34 can be restored to a vertical state under the action of its own gravity, and the limit clamp block 34 is detected to be restored to a vertical state through the inclination sensor (when the lower block 33 is in a vertical state, the inclination sensor detects that the limit clamp block 34 is in a horizontal state, and the electrorheological fluid is still energized). At this time, the electrorheological fluid in the elastic tube is energized and solidified, preventing the two limit clamp blocks 34 from continuing to move, so that even if the lower block 33 is tilted, the limit clamp block 34 can maintain a vertical state to perform the folding clamping operation (such as Fig.14 shown);

[0063] In addition, in order to avoid the situation where there is no liquid at the end of the elastic tube due to the falling of the internal liquid when the electrorheological fluid in the elastic tube is not energized, a repelling magnetic layer is designed to lift the elastic tube with built-in electrorheological fluid to ensure the uniformity of the electrorheological fluid distribution in the elastic tube.

[0064] In summary, the present application can effectively limit the plate 001 of different rolling forms during long-distance rolling by means of the adaptive limit unit 3, so that the rolled plate 001 can maintain a linear traction limit state during the rolling process, thereby ensuring the consistency of the rolling quality of the plate 001. The fixed rod 6 can also be replaced by the electric extension rod 7, and in conjunction with the pressure sensor, a linear traction effect can be achieved in the process of transitioning the rolled end from the position of the movable block 5 to the first adaptive limit unit 3, thereby ensuring stable clamping of the transition section. In addition, by replacing the magnetic suction plate 36 with a magnetic ring and the rotational connection design of the limit clamp 34 and the round rod, in conjunction with the design of the constraint part 9, when the folding length is greater than the vertical gap value between the surface of the plate 001 and the bottom surface of the lower vertical block 33 in the horizontal state, the lower vertical block 33 can continue to be lifted and the vertical clamping effect of the limit clamp 34 can be ensured.

[0065] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
