Description

Technical Field

[0001] This utility model relates to the technical field of aluminum coil production equipment, and in particular to a slitting device for cold-rolled aluminum coil production. Background Technology

[0002] In modern industry, cold-rolled aluminum coils are widely used in aerospace, automotive manufacturing, electronics, and many other sectors. As these industries increasingly demand higher precision and quality from aluminum coils, the importance of the slitting process is becoming increasingly apparent. Slitting is a crucial step in cutting large aluminum coils into multiple smaller coils according to specific specifications, directly affecting the dimensional accuracy, surface quality, and production efficiency of the finished aluminum coils.

[0003] Existing slitting equipment has poor adaptability. Traditional guiding devices cannot be flexibly adjusted to adapt to aluminum coils of different widths, and the rigid contact method is prone to bending and deformation of the aluminum coil edges, which limits the application scenarios of the equipment. During the conveying process, the coil is prone to scratches and other defects on the surface due to dragging and friction with the conveyor belt, which reduces the product qualification rate.

[0004] Therefore, those skilled in the art urgently need to develop a slitting device for cold-rolled aluminum coil production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slitting device for cold-rolled aluminum coil production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slitting device for cold-rolled aluminum coil production, comprising a frame, a support leg at the bottom of the frame, a conveying component on the frame, and a guide component, a pressing component, and a cutting component arranged sequentially above the conveying component along its movement direction.

[0007] The guiding assembly includes a guide box connected to the left and right sides of the frame. Each guide box has multiple horizontally arranged support rods on the side near the conveying assembly. Each support rod has a guide wheel rotatably mounted on the side near the conveying assembly via a bearing. The rotation axis of the guide wheel is perpendicular to the running direction of the conveying assembly. The other side of each support rod extends to the guide box and is connected to the adjusting assembly.

[0008] The pressing assembly includes a pressing base plate, and the bottom of both ends of the pressing base plate are provided with a first hydraulic rod connected to the frame. A pressing plate is provided at the lower middle position of the pressing base plate.

[0009] The cutting assembly includes a cutting base plate, with second hydraulic rods connected to the frame at both ends of the bottom of the cutting base plate. A cutting base is located at the lower center of the cutting base plate, and a cutting blade groove is formed at the bottom of the cutting base. A cutting blade is rotatably mounted in the cutting blade groove via a cutting shaft. A second drive motor for driving the cutting shaft to rotate is located on the side of the cutting base.

[0010] Preferably, the conveying assembly includes a driven shaft and a driving shaft rotatably disposed on the front and rear sides of the frame, a conveyor belt is provided between the driven shaft and the driving shaft, the conveyor belt is composed of multiple parallel strip structures, and a first drive motor for driving the driving shaft to rotate is connected to the frame.

[0011] Preferably, the number of gaps between the strip structures is consistent with the number of cutting blade grooves and they correspond to each other vertically, and the cutting shafts in each cutting blade groove are connected to each other.

[0012] Preferably, the adjustment component includes a support plate vertically disposed inside the guide box, and both ends of the support plate are provided with sliding grooves fixed inside the guide box, and the sliding grooves are slidably connected to the support plate.

[0013] Preferably, the support plate has a vertically placed adjustment plate on the side away from the support rod, and multiple sets of springs are provided between the adjustment plate and the support plate.

[0014] Preferably, both the front and rear ends of the guide box are equipped with horizontally placed lead screws that rotate rotatably. The lead screws are threadedly connected to the adjusting plate, and one end of the lead screw extends out of the guide box and is connected to the rocker arm.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The first drive motor drives the active shaft, which in turn drives the driven shaft via the conveyor belt, thus achieving smooth operation of the conveyor belt and effectively preventing surface scratches caused by dragging during the conveying process of aluminum coils; at the same time, the gap design between the strip structures of the conveyor belt provides clearance space for the cutting operation, ensuring a smooth slitting process.

[0017] 2. The second hydraulic rod drives the cutting seat plate and the cutting base to descend, so that the cutting blade contacts the aluminum coil. This allows multiple aluminum coils to be cut at the same time, greatly improving the cutting efficiency, meeting the needs of mass production, and achieving precise and efficient cutting operations.

[0018] 3. By controlling the rotation of the lead screw with a rocker arm, the distance between the adjusting plate and the support plate can be flexibly adjusted. In conjunction with multiple sets of springs, the support plate is pushed, which drives the support rod and guide wheels to move, so as to achieve precise adjustment of the distance between the guide wheels on both sides, which can adapt to the slitting of aluminum coils of different widths. The flexible buffer provided by the springs ensures that the guide wheels and the aluminum coils make flexible contact, avoids bending of the aluminum coils, and ensures the quality of the products after slitting.

[0019] 4. Feeding rollers and receiving rollers are installed at the feeding and discharging ends of the frame to realize automated feeding and receiving of aluminum coils; the first hydraulic rod controls the pressure plate to drive the pressure plate to descend, pressing the aluminum coil during the slitting process to prevent it from fluctuating up and down, ensuring the stability and reliability of the slitting process and improving processing accuracy.

[0028] Please see Figures 1-4 This utility model provides an embodiment: a slitting device for cold-rolled aluminum coil production, including a frame 1, a support leg 11 at the bottom of the frame 1, a conveying component on the frame 1, and a guide component 6, a pressing component 7 and a cutting component 8 arranged sequentially above the conveying component along its movement direction.

[0029] The guide assembly 6 includes guide boxes 61 connected to the left and right sides of the frame 1. Each guide box 61 has multiple horizontally arranged support rods 63 on the side near the conveying assembly. Each support rod 63 has a guide wheel 64 rotatably mounted on the side near the conveying assembly via a bearing. The rotation axis of the guide wheel 64 is perpendicular to the running direction of the conveying assembly. The other side of each support rod 63 extends to the guide box 61 and is connected to the adjustment assembly.

[0030] The pressing assembly 7 includes a pressing seat plate 71. Both ends of the pressing seat plate 71 are provided with first hydraulic rods 73 connected to the frame 1. A pressing plate 72 is provided at the lower middle position of the pressing seat plate 71.

[0031] The cutting assembly 8 includes a cutting base plate 81. Both ends of the cutting base plate 81 are provided with second hydraulic rods 82 connected to the frame 1. A cutting base 83 is provided at the lower middle position of the cutting base plate 81. A cutting blade groove is provided at the bottom of the cutting base 83. A cutting blade 86 is rotatably mounted in the cutting blade groove via a cutting shaft 85. A second drive motor 84 is provided on the side of the cutting base 83 to drive the cutting shaft 85 to rotate.

[0032] Furthermore, the conveying assembly includes a driven shaft 3 and a driving shaft 2 rotatably disposed on the front and rear sides of the frame 1. A conveyor belt 4 is provided between the driven shaft 3 and the driving shaft 2. The conveyor belt 4 is composed of multiple parallel strip-shaped structures. A first drive motor 5 for driving the driving shaft 2 to rotate is connected to the frame 1. The first drive motor 5 drives the driving shaft 2 to rotate, and the driving shaft 2 drives the driven shaft 3 to rotate via the conveyor belt 4, thereby realizing the rotation of the conveyor belt 4.

[0033] Furthermore, the number of gaps between the strip structures is consistent with the number of cutting blade grooves and they correspond to each other vertically. The cutting shafts 85 in each cutting blade groove are connected to each other. The cutting base plate 81 and the cutting base 83 are driven to descend by the second hydraulic rod 82. The cutting blade 86 contacts the aluminum coil, which can meet the requirements of multi-coil slitting. The gaps between the four strip structures of the conveyor belt are used to avoid misalignment.

[0034] Furthermore, the adjustment assembly includes a support plate 62 vertically disposed inside the guide box 61. Both ends of the support plate 62 are provided with horizontally fixed sliding grooves 69 inside the guide box 61. The sliding grooves 69 are slidably connected to the support plate 62. A vertically placed adjustment plate 66 is provided on the side of the support plate 62 away from the support rod 63. Multiple sets of springs 67 are provided between the adjustment plate 66 and the support plate 62. Both the front and rear ends inside the guide box 61 are rotatably provided with horizontally placed lead screws 65. The lead screws 65 are threadedly connected to the adjustment plate 66. One end of the lead screw 65 extends out of the guide box 61 and is connected to the rocker arm 68.

[0035] The rocker arm 68 drives the lead screw 65 to rotate, thereby controlling the left and right movement of the adjusting plate 66, which adjusts the distance between the adjusting plate 66 and the support plate 62. Then, the support plate 62 is pushed by multiple sets of springs 67, which in turn drives the guide wheel 64 to move, thereby adjusting the distance between the two guide wheels 64 to meet the slitting requirements of aluminum coils of different widths. At the same time, the multiple sets of springs 67 can provide flexible contact between the guide wheel 64 and the aluminum coil, avoiding bending of the aluminum coil.

[0036] The working principle of this utility model is as follows: Before use, the feeding end and the receiving end of the frame 1 are first set with feeding rollers and receiving rollers. The aluminum coil is first placed on the feeding roller. After passing through the guide component 6, the pressing component 7 and the cutting component 8 in sequence, the aluminum coil is wound onto the corresponding receiving roller. The aluminum coil is fed and unloaded by driving the receiving roller. The feeding roller and the receiving roller are existing technologies, so they will not be described in detail.

[0037] When the aluminum coil passes through the guide assembly 6, its position is controlled by the guide wheels 64 on both sides, and the distance between the guide wheels 64 on both sides is adjusted by the rocker arm 68; then it passes through the pressing assembly 7, and the pressing seat plate 71 is controlled by the first hydraulic rod 73 to drive the pressing plate 72 to descend, so as to avoid up and down fluctuations during the cutting process; then the cutting blade 86 is controlled by the second drive motor 84 to cut the aluminum coil.

[0038] During the cutting process, the first drive motor 5 drives the drive shaft 2 to rotate, and the drive shaft 2 drives the driven shaft 3 to rotate through the conveyor belt 4, thereby realizing the rotation of the conveyor belt 4 and preventing the aluminum coil from being dragged on the conveyor belt 4, causing surface scratches.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
