Description

Technical Field

[0001] The invention relates to the technical field of aluminum material production equipment, and in particular to a segmented continuous rolling device for aluminum strips. Background Art

[0002] In the production process of aluminum strip, the strength and hardness of the strip need to be changed through the rolling process, and the distance between the upper and lower rollers is adjusted to make the strip obtain the required thickness. At present, the rollers used in the rolling device are usually of an integral full-length structure. When the width of the strip is large, the axial length of the roller is also correspondingly longer. However, as the length of the roller increases, the roller is not only easy to deform completely, resulting in differences in the strength of the rolling force applied to the strip by various axial parts of the roller, but also difficult to ensure the horizontality of the roller, resulting in inconsistent rolling thickness of the strip with the same width, and the rolling quality of the strip cannot be guaranteed. Summary of the invention

In addition, the overall weight of the single first rolling roller and the second rolling roller is reduced, and a uniform force component is provided to cooperate with them. The first rolling roller and the second rolling roller are subjected to force at multiple points, which can reduce the bending risk of the first rolling roller and the second rolling roller as a whole and ensure the rolling quality.

The unwinding mechanism 01 is provided with the aluminum coil to be rolled and the aluminum strip is released. The aluminum strip to be rolled is rolled to the required thickness by several groups of rolling rollers 2 in the rolling mechanism 02 and then wound by the winding mechanism 03. Among them, the unwinding mechanism 01 and the rolling mechanism 02 both include a frame body, an axis perpendicular to the feeding direction, and a motor for driving the axis to rotate, which are the same as the prior art.

The control console 08 controls the various mechanism components in the device to perform automatic work and linkage through automatic control technology such as PLC.

The rolling gap between the two first rolling rollers 5 and the rolling gap between the two second rolling rollers 6 in each rolling roller group 2 are the same.

[0044] like Figure 1 and Figure 2 As shown, the first rolling roller 5 is provided with a plurality of first rolling sections 7 coaxial therewith in an array along its length direction, and the second rolling roller 6 is provided with a plurality of second rolling sections 8 coaxial therewith in an array along its length direction.

The first rolling section 7 and the second rolling section 8 are arranged at intervals, and their rolling surfaces do not overlap and completely cover the width direction of the aluminum strip.

[0045] like Figure 1 and Figure 2As shown, the rolling gaps of the multiple rolling roller groups 2 are reduced in sequence along the feeding direction, and the aluminum strip is rolled to the required thickness in batches. The first rolling section 7 and the second rolling section 8 in each rolling roller group 2 perform two segmented rolling in the width direction of the aluminum strip, thereby achieving segmented rolling of the length and width of the aluminum strip, ensuring the rolling accuracy of the aluminum strip and reducing the damage to the rolling roller group 2. Among them, the rolling stand 1 is provided with a plurality of conveying rollers arranged along its width direction along its length direction, and two conveying rollers are arranged in parallel at the same position. The aluminum strip passes through the upper and lower conveying rollers and is conveyed forward. In order to keep the drawings clear, only the conveying rollers at the two ends of the rolling stand 1 are shown in the drawings, and the rest of the positions are omitted.

[0046] like Figure 1 and Figure 2 As shown, in order to ensure the horizontality and uniform force of the first rolling roller 5 and the second rolling roller 6, a uniform force component 04 is respectively provided at the first roller group 3 and the second roller group 4, and the uniform force component 04 cooperates with the corresponding first rolling roller 5 and the second rolling roller 6. The overall weight of the first rolling roller 5 and the second rolling roller 6 is reduced, and with the cooperation of the uniform force component 04, the first rolling roller 5 and the second rolling roller 6 are subjected to force at multiple points, which can reduce the bending risk of the first rolling roller 5 and the second rolling roller 6 as a whole and ensure the rolling quality.

[0047] Specifically, Figure 2 and Figure 3 As shown, each group of uniform force components 04 includes a uniform force frame 9 arranged up and down and corresponding to the corresponding first rolling roller 5 and second rolling roller 6 respectively. The uniform force frame 9 is arranged along the width direction of the rolling frame 1, and a plurality of vertically arranged uniform force rods 10 are arranged in an array along the length direction of the uniform force frame 9. The plurality of uniform force rods 10 are vertically slidably installed on the corresponding uniform force frame 9. A uniform force ring 11 is arranged at one end of the uniform force rod 10 close to the corresponding first rolling roller 5 and second rolling roller 6. The uniform force ring 11 is arranged at intervals from the corresponding first rolling section 7 and second rolling section 8 and its outer diameter is smaller than the outer diameter of the corresponding first rolling section 7 and second rolling section 8. The uniform force ring 11 is sleeved on the corresponding first rolling roller 5 and second rolling roller 6 and is arranged coaxially therewith.

[0049] like Figure 3 and Figure 4 As shown, in order to ensure the supporting effect of the force-uniforming ring 11 on the corresponding first rolling roller 5 and second rolling roller 6, a plurality of rolling grooves 12 are arranged in a circumferential array on the inner wall of the force-uniforming ring 11, and a rolling seat 13 that slides radially along the force-uniforming ring 11 is installed in each rolling groove 12. A contact spring 14 arranged along the sliding direction is connected between the rolling seat 13 and the rolling groove 12, and a plurality of contact springs 14 are arranged in a circumferential array around the force-uniforming ring 11. A ball 15 is rollingly installed on each rolling seat 13, and a plurality of ball 15 are arranged in a circumferential array around the inner wall of the force-uniforming ring 11 and rollingly cooperate with the outer wall of the corresponding first rolling roller 5 and second rolling roller 6. The inner wall of the force-uniforming ring 11 rolls with the corresponding first rolling roller 5 and second rolling roller 6 through a plurality of ball 15, so that the force-uniforming ring 11 supports the corresponding first rolling roller 5 and second rolling roller 6, while avoiding interference between the rotation of the force-uniforming ring 11 and the first rolling roller 5 and second rolling roller 6.

[0050] like Figure 3 and Figure 4 As shown, in order to further ensure the horizontality of the first rolling roller 5 and the second rolling roller 6 and the rolling quality in the width direction of the aluminum strip, a plurality of positioning pieces 16 located on one side of the force equalizing ring 11 are arranged in an array on the side walls of the first rolling roller 5 and the second rolling roller 6 along their length direction. The positioning pieces 16 are arranged along the radial direction of the corresponding first rolling roller 5 and the second rolling roller 6, and the ends thereof away from the corresponding first rolling roller 5 and the second rolling roller 6 are located inside the outer diameter of the corresponding first rolling section 7 and the second rolling section 8. The end of each force equalizing rod 10 away from the force equalizing ring 11 is connected to a leveling cylinder 17 for driving it to slide vertically. The force equalizing frame 9 is provided with a plurality of distance meters 18 corresponding to the positioning pieces 16 along its length direction. The distance meters 18 are connected to the leveling cylinder 17 close to them for communication feedback control.

[0051] like Figure 3 and Figure 4 As shown, the rangefinder 18 measures the distance between itself and the corresponding positioning piece 16, and controls the corresponding leveling cylinder 17 through communication feedback based on the measurement result to drive the corresponding uniform force rod 10 to drive the corresponding first rolling roller 5 and second rolling roller 6 to vertically rise and fall through the uniform force ring 11, thereby achieving horizontal adjustment of the entire first rolling roller 5 and the second rolling roller 6, and ensuring the levelness of both ends of the first rolling section 7 and the second rolling section 8, thereby ensuring the rolling quality of the aluminum strip.

[0052] like Figure 1 and Figure 2As shown, a plurality of anti-deviation components 05 are provided on the rolling stand 1 along the feeding direction, and the plurality of anti-deviation components 05 and the plurality of rolling roller groups 2 and the plurality of first roller groups 3 and second roller groups 4 are arranged at intervals, and the plurality of rolling roller groups 2 are located between the anti-deviation components 05 at both ends of the rolling stand 1.

[0053] Specifically, Figure 2 and Figure 5 As shown, each group of anti-deflection components 05 includes anti-deflection plates 19 located on both sides of the rolling frame 1 and arranged along the length direction of the rolling frame 1. Each group of two anti-deflection plates 19 is installed on the rolling frame 1 in a limited sliding manner along the width direction of the rolling frame 1. A support plate 20 is provided on the side where the two anti-deflection plates 19 are close to each other and is arranged along the length direction and is horizontally perpendicular to the anti-deflection plates 19. A limit plate 21 is provided above the support plate 20 and is parallel to the support plate 20 and is vertically slidably installed on the anti-deflection plate 19.

Among them, in order to realize the synchronous sliding of the anti-deflection plates 19 on both sides, an anti-deflection screw rod 191 arranged along its width direction is installed on the rolling frame 1 for positioning and rotation. The anti-deflection plates 19 with limited sliding at both ends of the anti-deflection screw rod 191 are spirally connected to the anti-deflection screw and their thread rotation directions are opposite. One end of the anti-deflection screw rod 191 is connected to an anti-deflection motor 192 for driving it to position and rotate.

[0054] like Figure 2 and Figure 5 As shown, according to the width of the aluminum strip to be rolled, the two anti-deflection plates 19 in each anti-deflection assembly 05 are driven to slide along the width direction of the rolling stand 1, and the distance between the two anti-deflection plates 19 is adjusted so that the two anti-deflection plates 19 limit the aluminum strip to be rolled from both sides to prevent the aluminum strip from deflecting during transportation. The support plate 20 supports the aluminum strip from the lower surface on both sides, and the limit plate 21 limits the aluminum strip from the upper surface on both sides to reduce the upward movement of the aluminum strip during transportation. The limit plate 21 is vertically slidably installed on the anti-deflection plate 19, and the distance between the limit plate 21 and the support plate 20 can be adjusted according to the thickness of the aluminum strip.

The axes of the plurality of vertical wheels 22 are vertically arranged and are installed on the anti-deflection plate 19 to be positioned and rotated around their axes. A plurality of horizontal wheels 23 arranged in an array are embedded in the upper end surface of the support plate 20 and the lower end surface of the limiting plate 21 along their length direction. The axes of the plurality of horizontal wheels 23 are arranged along the width direction of the rolling stand 1 and are installed on the corresponding support plate 20 and limiting plate 21 to be positioned and rotated around their axes. The plurality of vertical wheels 22 and horizontal wheels 23 on the same side are arranged at intervals. The plurality of vertical wheels 22 and the plurality of horizontal wheels 23 limit the support and convey the aluminum strip from the sides and the upper and lower surfaces on both sides of the aluminum strip, reduce the wear of the aluminum strip during the conveying process, and thus reduce the rolling loss of the aluminum strip.

[0056] like Figure 1 and Figure 6 As shown, in order to adjust the rolling gap, lifting seats 24 are provided at both ends of the first rolling roller 5 and the second rolling roller 6, and both ends of the first rolling roller 5 and the second rolling roller 6 are positioned and rotatably installed on the corresponding lifting seats 24.

[0057] like Figure 2 and Figure 3As shown, in order to realize the vertical drive adjustment of the lifting seat 24, a driving assembly 06 for driving the lifting seat 24 to slide vertically is provided between the first roller group 3 and the second roller group 4 in each group of rolling roller groups 2. Specifically, the driving assembly 06 includes a driving rod 25 provided between the first roller group 3 and the second roller group 4 in each group of rolling roller groups 2 and located on both sides of the rolling frame 1. The driving rod 25 is provided along the length direction of the rolling frame 1 and has vertically provided linkage racks 26 at both ends. The driving rod 25 is vertically slidably installed on the rolling frame 1 and is connected to a driving lifting cylinder 251 for driving it to slide vertically. A linkage gear 27 meshing with the corresponding linkage rack 26 and having an axis arranged along the width direction of the rolling frame 1 is positioned and rotatably installed on the rolling frame 1. The axis of the linkage gear 27 is located on the symmetric plane of the two lifting seats 24 located at the same end and corresponding to each other in the first roller group 3 and the second roller group 4. Two lifting seats 24 located at the same end and corresponding to each other are respectively provided with vertical driving racks 28 arranged opposite to each other. Each group of two driving racks 28 is respectively located at both sides of the corresponding linkage gear 27 and meshes with the linkage gear 27 .

The recovery box 33 has a filtering function, and its specific filtering structure can be selected from the prior art such as a filter screen, which is not shown in the figure.

[0060] like Figure 1 and Figure 6 As shown, the spray liquid in the spray box 32 is sprayed onto the corresponding first rolling section 7 and the second rolling section 8 through four spray pipes 31 and a plurality of spray arc plates 30 connected to the spray pipes 31 in a one-to-one correspondence, providing lubrication and cooling for rolling. The excess spray liquid is recovered into the recovery box 33 and filtered, and then flows back into the spray box 32 through the return pipe 331 for use, so as to avoid the spray liquid splashing and affecting the rolling environment, and the spray liquid can be recycled and reused. In this way, the spray arc plate 30 is used to spray the corresponding first rolling section 7 and the second rolling section 8, without the need for repeated spraying twice to cover the width direction of the aluminum strip, and the spray liquid is sprayed and used immediately, which ensures its use effect and reduces its use cost, avoiding waste.

[0061] Among them, Figure 6As shown, the inner wall of each spray arc plate 30 is provided with a cleaning arc sheet 34 that cooperates with it and fits with the outer wall of the corresponding first rolling section 7 and the second rolling section 8.

[0062] Working principle and use method of the present invention:

[0063] The unwinding mechanism 01 is equipped with an aluminum coil to be rolled and releases the aluminum strip. After the aluminum strip to be rolled is rolled to the required thickness by several groups of rolling rollers 2 in the rolling mechanism 02, it is rolled by the winding mechanism 03. The rolling gaps of the multiple groups of rolling rollers 2 are reduced in sequence along the feeding direction, and the aluminum strip is rolled to the required thickness in batches in the length direction. The first rolling section 7 of the first roller group 3 and the rolling section of the second roller group 4 in each group of rolling rollers 2 roll the aluminum strip in batches in the width direction, thereby achieving segmented rolling of the length and width of the aluminum strip. During the rolling process, the spray assembly 07 adds spray liquid to the first rolling section 7 and the second rolling section 8 to provide lubrication and cooling for rolling.

[0064] The overall weight of the single first rolling roller 5 and the second rolling roller 6 is reduced, and a uniform force component 04 is provided to cooperate with them. The first rolling roller 5 and the second rolling roller 6 are subjected to force at multiple points, which can reduce the bending risk of the first rolling roller 5 and the second rolling roller 6 as a whole, and ensure the rolling quality. The anti-deviation component 05 can prevent the aluminum strip from deviating during the rolling and conveying process, and the anti-deviation component 05 and the rolling roller group 2 are arranged at intervals, which can prevent part of the surface of the aluminum strip from being repeatedly rolled or missed by the first rolling part 7 and the second rolling part 8, thereby ensuring the comprehensive rolling of the aluminum strip, the rolling quality and the rolling efficiency, and reducing the rolling loss of the aluminum strip.
