In the actual processing process, the strip output is prone to distortion, resulting in poor forming effect.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-6 As shown, a production system for automatically adjusting the thickness error of cast and rolled copper and aluminum strips comprises a support 1 in a vertical frame structure, on which an upper pressure conveying roller 3 and a lower pressure conveying roller 4 parallel to each other are arranged, the upper pressure conveying roller 3 is located directly above the lower pressure conveying roller 4, and a flat channel for the strip to pass through is reserved between the upper pressure conveying roller 3 and the lower pressure conveying roller 4; a lifting device for adjusting the relative distance between the upper pressure conveying roller 3 and the lower pressure conveying roller 4 is arranged between the upper pressure conveying roller 3 and the lower pressure conveying roller 4, the lifting device provides a corresponding pressing force to ensure the compression and deformation effect of the strip, the lifting device is connected to the signal output end of the AGC control system, a conveying device 5 located on one side of the upper pressure conveying roller 3 and the lower pressure conveying roller 4 is arranged on the support 1, the conveying surface of the conveying device 5 is parallel to the upper pressure conveying roller 3, and the conveying direction of the conveying device 5 is perpendicular to the upper pressure conveying roller 3, and an AGC thickness gauge 2 is arranged on the support 1 directly above the conveying device 5, and the AGC thickness gauge 2 is connected to the AGC control system. The AGC thickness gauge 2 monitors the thickness change of the strip in real time and sends the detection signal to the AGC control system, which performs negative feedback adjustment on the lifting device to ensure the uniformity of the strip thickness.

[0030] Specifically, similar to the existing guide structure, in this embodiment, the bracket 1 is provided with a slide groove 6 at both ends of the corresponding upper pressure conveying roller 3 and the lower pressure conveying roller 4, the length direction of the slide groove 6 is perpendicular to the conveying surface of the conveying device 5, and an upper sliding seat 7 and a lower sliding seat 8 are slidably provided in the slide groove 6, and the two ends of the upper pressure conveying roller 3 are respectively connected to an upper sliding seat 7, and the two ends of the lower pressure conveying roller 4 are respectively connected to a lower sliding seat 8, and one of the upper sliding seats 7 is provided with a first servo motor 9, and one of the lower sliding seats 8 is provided with a second servo motor 10, and the output shaft of the first servo motor 9 is connected to the upper pressure conveying roller 3, and the output shaft of the second servo motor 10 is connected to the lower pressure conveying roller 4, and the upper sliding seat 7 and the lower sliding seat 8 are both connected to the execution end of the lifting device. The first servo motor 9 and the second servo motor 10 are output synchronously, so that the upper pressure conveying roller 3 and the lower pressure conveying roller 4 rotate to apply a transmission torque to the strip, and the transmission rate is usually consistent with the output end of the strip, and the transmission rate can also be adjusted according to actual needs, and the extrusion deformation of the strip is controlled in coordination with the lifting device.

[0031] In order to provide sufficient extrusion torque, the present embodiment preferably uses hydraulic lifting, and its lifting device includes an upper hydraulic cylinder 11 and a lower hydraulic cylinder 12. The piston rod of the upper hydraulic cylinder 11 vertically penetrates downward into the slide 6 and is fixedly connected to the upper sliding seat 7, and the lower hydraulic cylinder 12 vertically penetrates upward into the slide 6 and is fixedly connected to the lower sliding seat 8. The upper hydraulic cylinder 11 and the lower hydraulic cylinder 12 are both connected to the AGC control system. In addition to meeting the strip extrusion requirements by adjusting the hydraulic torque, the hydraulic cylinder 11 and the lower hydraulic cylinder 12 can also drive the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4 to adjust the vertical height, so that the height of the channel between them can also be further adjusted to adapt to different strip output ports.

[0032] Furthermore, the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4 are built with a temperature adjustment system, which is controlled by adjusting the water pressure flow of the roller core cooling water; the temperature adjustment system includes a flow control solenoid valve 13, a delivery pipe 14, and a coolant channel 15. A coolant channel 15 is coaxially provided on each of the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4. The two ends of the upper pressure conveyor roller 3 are each connected to a delivery pipe 14 through a dynamic seal, and the two ends of the lower pressure conveyor roller 4 are each connected to a delivery pipe 14 through a dynamic seal. A flow control solenoid valve 13 is provided on one of the delivery pipes 14 connected to the upper pressure conveyor roller 3, and a flow control solenoid valve 13 is also provided on one of the delivery pipes 14 connected to the lower pressure conveyor roller 4. The flow control solenoid valve 13 is connected to the AGC control system. The flow control solenoid valve 13 adjusts the amount of liquid entering the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4, and the delivery pipe 14 is externally connected to a heating or heat dissipation structure, thereby adjusting the surface temperature of the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4.

[0033] Furthermore, the AGC thickness gauge 2 is an X-ray thickness gauge. When the X-rays penetrate the strip, the rays are reflected, scattered or absorbed by the strip, and the intensity of the rays decays accordingly. By detecting the positive correlation between the attenuation and the surface density of the strip, the change of the material can be judged, and its thickness usually fluctuates linearly.

[0034] In addition, since the strip needs to be wound and stored, a curling guide assembly connected to the conveying device 5 is installed on the bracket 1 to further guide the transmission direction of the strip, guiding it from a horizontal state to a curled state, wherein the curling guide assembly is equipped with a winding storage assembly for further storage, and the curling guide assembly and the winding storage assembly are synchronously movable and adjusted to ensure that they change with the winding amount of the strip.

[0035] Meanwhile, unlike conventional fixed guide channels, the curling guide assembly in this embodiment includes support plates 51 vertically and symmetrically mounted on both sides of the bracket 1, and a plurality of arc-shaped guide grooves 52 are provided on the support plates 51, the inner arc of the guide grooves 52 is opposite to the winding storage assembly, guide blocks 53 are slidably mounted in the guide grooves 52, guide rods 54 are connected between the guide blocks 53, guide plates 55 are rotatably mounted on the guide rods 54, limiting grooves are respectively provided on both sides of the guide plates 55, and limiting buckles 56 are provided at the ends of the guide plates 55, the guide plates 55 on the guide rods 54 overlap with the guide plates 55 on another adjacent guide rods 54, and the limiting grooves of the guide plates 55 are slidably connected with the limiting buckles 56. Each guide block 53 slides relative to the guide groove 52 and adjusts the position of the guide rod 54 and the orientation of the guide plate 55, and a plurality of guide plates 55 are connected one by one under the limiting action of the limiting grooves and the limiting buckles 56 to form a guide surface, which includes a plurality of independent planes or arc surfaces. When the strip is transferred to the guide surface, it is gradually transferred upward in an arc shape and is wound and stored as the winding and storage assembly is driven.

[0036] It can be seen that the winding storage assembly adopts active winding storage and is equipped with a guiding structure, specifically including a storage groove 61 arranged on the support plate 51, a storage block 62 is slidably installed in the storage groove 61, a storage roller 64 is rotatably installed between the storage blocks 62 through a storage motor 63, a rotating disk 65 is fixedly connected on both sides of the storage roller 64, the storage block 62 is connected to a fixed disk 66 opposite to the rotating disk 65, a storage frame opening 67 that can slide in the circumferential direction is installed at the edge of the fixed disk 66, a speed change gear set that meshes with the storage motor 63 is installed between the fixed disk 66 and the rotating disk 65, and the speed change gear set meshes with the storage frame opening 67 through an adjusting gear rack set. As the position of each guide plate 55 in the curling guide assembly changes, the center position of the storage roller 64 is also adjusted. This position adjustment is mainly used to adapt to the change in the winding thickness of the strip on the storage roller 64. As the winding amount of the strip increases, the storage roller 64 also descends to reduce the distance from the curling guide assembly, and the bending curvature of the strip on the curling guide assembly also decreases.

[0037] Obviously, in order to ensure the synchronous movement of the curling guide assembly and the winding storage assembly, the guide block 53 is fixedly connected with an arc-shaped synchronous rack 71, and a synchronous gear 72 meshing with the synchronous rack 71 is installed on the support plate 51. The synchronous gear 72 is connected to the synchronous motor 74 through a transmission gear set, and the synchronous gear 72 group is meshed with a synchronous screw 76 installed on one side of the storage groove 61 through a reversing gear set 75. The synchronous screw 76 is connected to the storage block 62. The curling guide assembly and the winding storage assembly keep synchronous movement to avoid excessive bending of the strip and deformation that affects the storage effect.

[0038] A production method of a production system for automatically adjusting the thickness error of cast-rolled copper and aluminum strips, comprising the following steps:

[0039] S1: The side of the support 1 facing away from the conveying device 5 is docked at the output port of the step of casting and rolling the copper and aluminum into strips, so that the produced strips can be conveyed to the conveying device from between the upper pressure conveying roller 3 and the lower pressure conveying roller 4;

[0040] S2: The distance between the upper pressure conveying roller 3 and the lower pressure conveying roller 4 is adjusted according to the difference between the actual thickness value measured by the AGC thickness gauge 2 and the preset thickness value through the AGC control system. If the thickness value measured by the AGC thickness gauge 2 is greater than the preset thickness value, the AGC control system enables the lifting mechanism to reduce the distance between the upper pressure conveying roller 3 and the lower pressure conveying roller 4. At the same time, the temperature regulating system is controlled by the AGC control system to increase the temperature of the upper pressure conveying roller 3 and the lower pressure conveying roller 4. If the thickness value measured by the AGC thickness gauge 2 is less than the preset thickness value, the AGC control system enables the lifting mechanism to increase the distance between the upper pressure conveying roller 3 and the lower pressure conveying roller 4. At the same time, the temperature regulating system is controlled by the AGC control system to reduce the temperature of the upper pressure conveying roller 3 and the lower pressure conveying roller 4.

[0041] S3: The curling guide assembly guides the strip to bend, and the guide plate 55 moves synchronously to adjust the relative distance, and the bending curvature of the strip is adjusted accordingly. The storage roller 64 in the winding and storage assembly rotates to store the strip, and at the same time, the storage roller 64 slides along the storage groove 61 and adjusts the relative position synchronously with the guide plate 55.

[0042] In summary, the principle of this embodiment is that the AGC control system controls the distance between the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4 according to the feedback information of the AGC thickness gauge, and adjusts the thickness of the strip formed after the copper and aluminum are cast and rolled by controlling the distance between the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4. The first servo motor 9 and the second servo motor 10 are respectively used to drive the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4 to rotate, and the flow rate of the coolant passing through the interior of the upper pressure conveyor roller 3 and the interior of the lower pressure conveyor roller 4 is controlled by the flow control solenoid valve to realize heat exchange, thereby adjusting the temperature of the upper pressure conveyor roller 3 and the lower pressure conveyor roller 4.
