Technical Field
[0001] This application relates to the technical field of slitting machines, and in particular to a vertical slitting machine. Background Technology
[0002] A vertical slitting machine is a metal coil processing equipment that can longitudinally slit wide metal coils into narrow strips of a specific width, and then rewind the slit strips.
[0003] In related technologies, vertical slitting machines generally include a frame, an unwinding mechanism, conveyor rollers, a slitting mechanism, and a rewinding mechanism. The unwinding mechanism unwinds the metal coil. Multiple conveyor rollers are rotatably connected to the frame, and the metal coil passes over these rollers, which guide and transport the metal coil. The slitting mechanism includes a cutter shaft, cutters, and a slitting drive source. Specifically, the cutters are circular cutters. The cutter shaft is rotatably connected to the frame, and the circular cutters are fixedly connected to it. The slitting drive source drives the cutter shaft to rotate. The metal coil passes between adjacent circular cutters, which compress the coil, causing plastic deformation at the cutter location and tearing it apart. After slitting, the rewinding mechanism rewinds the slit metal coil.
[0004] For related technologies, when the metal coil has a certain thickness, the shear strength of the metal coil is high, requiring a large cutting force, which can easily cause elastic deformation of the frame and cutter shaft, resulting in uncontrolled tool clearance, increased burrs on the cross-section of the metal coil, and accelerated tool wear. Summary of the Invention

The extrusion mechanism includes a support frame, an extrusion drive assembly, a rotation drive source, an extrusion roller, and a pressure roller; the extrusion roller and the pressure roller are both mounted on the support frame, and the rotation drive source drives the extrusion roller and the pressure roller to rotate; one extrusion roller and one pressure roller form a set of extrusion assemblies, and multiple sets of extrusion assemblies are provided; the extrusion drive assembly is used to cause the extrusion roller and the pressure roller to extrude the coiled workpiece, so that an indentation is extruded in a predetermined area of the coiled workpiece, and the slitting mechanism slits the indentation area of the coiled workpiece.
[0007] By adopting the above technical solution, an extrusion mechanism is used to indent a predetermined area of the coil workpiece before slitting. This causes prestress concentration and localized plastic deformation in the predetermined area, reducing the shear strength of that area. This allows the subsequent slitting mechanism to complete the slitting with a smaller cutting force, effectively improving the problem of elastic deformation of the frame and cutter shaft caused by excessive cutting force, reducing the risk of tool clearance loss, and thus reducing burrs on the metal coil cross-section and extending tool life. This application is applicable to the slitting of metal coils with a certain thickness. Multiple extrusion components extrude the coil workpiece, causing certain metal fatigue in the predetermined area of the coil workpiece, which is beneficial for the subsequent slitting mechanism to slitting the coil workpiece.

Thus, the axial positions of the extrusion roller, the first pressing roller, the pressure grooved roller and the second pressing roller can be flexibly adjusted according to the width and indentation position requirements of the coil workpiece, adapting to the processing requirements of different specifications of coils, improving the versatility and adaptability of the equipment, and facilitating position compensation adjustment after the extrusion roller and the pressure grooved roller have a certain wear, which is beneficial to adjusting the axial force of the extrusion roller and the pressure grooved roller.
[0014] Optionally, the first axial adjustment assembly includes multiple adjusting cylinders and a locking element. The multiple adjusting cylinders are respectively located on both sides of the extrusion roller. The adjusting cylinders are threadedly connected to the extrusion roller shaft. The adjusting cylinders push the extrusion roller and the first pressing roller to move axially along the extrusion roller shaft. The locking element is used to lock the position of the adjusting cylinders on the extrusion roller shaft.
[0015] By adopting the above technical solution, the adjusting cylinder is threadedly connected to the extrusion roller shaft. By turning the adjusting cylinder, the position of the extrusion roller and the first pressing roller can be precisely adjusted. The adjustment method is simple and reliable, and the adjustment accuracy is high.

[0017] By adopting the above technical solution and setting a pressure sensor between the adjusting cylinder and the first pressing roller, the axial force of the extrusion roller can be monitored in real time. When the force of the extrusion roller changes due to wear, it can provide timely feedback and prompt the operator to adjust the position.

[0026] In summary, this application includes at least one of the following beneficial effects: 1.

[0029] The following combination Figures 1 to 6This application will be described in further detail.
[0030] This application provides a vertical slitting machine.
[0031] refer to Figure 1 and Figure 2 A vertical slitting machine includes a frame 1, an unwinding mechanism 2, a conveying roller 3, an extrusion mechanism 4, a slitting mechanism 6, and a winding mechanism 7. The unwinding mechanism 2 is located on one side of the frame 1 and is mounted on the ground. The unwinding mechanism 2 unwinds the roll material workpiece. In this application, the roll material workpiece is a metal roll such as aluminum foil or copper strip.
[0032] refer to Figure 1 Multiple conveyor rollers 3 are provided, and all conveyor rollers 3 are rotatably connected to the frame 1. The roll material is wound around the conveyor rollers 3, which guide and support the roll material to ensure that the roll material maintains appropriate tension and orientation during transmission.
[0033] refer to Figure 2 and Figure 3 The extrusion mechanism 4 includes a support frame 41, an extrusion drive assembly 42, a rotation drive source 43, an extrusion roller 44, and a pressure roller 45. The extrusion drive assembly 42 includes an extrusion drive source 421, a slider 422, and a pressure sensor 423. The support frame 41 is fixedly connected to the frame 1 by bolts, and the slider 422 is slidably connected to the support frame 41. The extrusion drive source 421 is an electric push rod. The body of the extrusion drive source 421 is fixedly connected to the support frame 41, and the telescopic end of the extrusion drive source 421 is fixedly connected to the pressure sensor 423. The pressure sensor 423 is fixedly connected to the slider 422.
[0034] refer to Figure 2 and Figure 3 The extrusion roller 44 is rotatably connected to the slider 422, and the pressure roller 45 is rotatably connected to the support frame 41. The axes of the extrusion roller 44 and the pressure roller 45 are parallel, forming an extrusion gap between them for the coiled material to pass through. Multiple rotation drive sources 43 are provided, each corresponding to one of the extrusion roller 44 and the pressure roller 45. The body of the rotation drive source 43 corresponding to the extrusion roller 44 is fixedly connected to the slider 422, and the body of the rotation drive source 43 corresponding to the pressure roller 45 is fixedly connected to the support frame 41. The output ends of the rotation drive sources 43 drive the extrusion roller 44 and the pressure roller 45 to rotate.
[0035] refer to Figure 2 and Figure 3The extrusion drive source 421 drives the slider 422 to slide vertically, thereby causing the extrusion roller 44 to move closer to or further away from the pressure roller 45, adjusting the extrusion pressure and the size of the extrusion gap between the extrusion roller 44 and the pressure roller 45. The pressure sensor 423 can detect the thrust applied to the slider 422 by the extrusion drive source 421 in real time, thus indirectly reflecting the magnitude of the extrusion pressure exerted on the coiled workpiece by the extrusion roller 44 and the pressure roller 45. By setting the pressure sensor 423, the extrusion pressure can be controlled to ensure that the extrusion pressure is always within the optimal range, thereby improving the stability and controllability of processing quality.
[0036] refer to Figure 3 and Figure 4 The extrusion roller 44 includes an extrusion roller shaft 441 and an extrusion wheel 442. The extrusion roller shaft 441 is rotatably connected to the slider 422. The rotation drive source 43 can drive the extrusion roller shaft 441 to rotate. The extrusion wheel 442 is slidably connected to the extrusion roller shaft 441 and rotates synchronously with the extrusion roller shaft 441. The extrusion wheel 442 can move axially along the extrusion roller shaft 441. The pressure roller 45 includes a pressure roller shaft 451 and a pressure grooved wheel 452. The pressure roller shaft 451 is rotatably connected to the support frame 41. The rotation drive source 43 can drive the pressure roller shaft 451 to rotate. The pressure grooved wheel 452 is slidably connected to the pressure roller shaft 451 and rotates synchronously with the pressure roller shaft 451. The pressure grooved wheel 452 can move axially along the pressure roller shaft 451.
[0037] refer to Figure 4 and Figure 5 The outer edge of the extrusion roller 442 is formed with a flange, and the outer edge of the pressure groove roller 452 is formed with an annular groove. The flange and the annular groove cooperate. When the coil workpiece passes between the extrusion roller 442 and the pressure groove roller 452, the flange presses into the surface of the coil workpiece, and the annular groove provides clearance space, thereby extruding an indentation in a predetermined area of the coil workpiece.
[0038] refer to Figure 4 and Figure 5Multiple first pressing rollers 443 are slidably connected to the extrusion roller shaft 441. The multiple first pressing rollers 443 are located on both sides of the extrusion roller 442. The first pressing rollers 443 rotate synchronously with the extrusion roller shaft 441 and can move axially along the extrusion roller shaft 441. Multiple second pressing rollers 453 are slidably connected to the pressure roller shaft 451. The multiple second pressing rollers 453 are located on both sides of the pressure groove roller 452. The second pressing rollers 453 rotate synchronously with the pressure roller shaft 451 and can move axially along the pressure roller shaft 451. The first pressing roller 443 corresponds to the second pressing roller 453. When the extrusion roller 44 and the pressure roller 45 extrude the coil workpiece, the first pressing roller 443 and the second pressing roller 453 clamp and press the two sides of the indentation on the coil workpiece. This can effectively improve the material stability on both sides of the indentation area, improve the problem of wrinkles or lateral displacement of the coil workpiece during the extrusion process, and ensure the accuracy of the indentation position and the uniformity of the indentation quality.
[0039] refer to Figure 4 and Figure 5 A first axial adjustment assembly 47 is provided on the extrusion roller shaft 441. The first axial adjustment assembly 47 is used to adjust the axial movement distance of the extrusion roller 442 and the first pressing roller 443 on the extrusion roller shaft 441. A second axial adjustment assembly 48 is provided on the pressure roller shaft 451. The second axial adjustment assembly 48 is used to adjust the axial movement distance of the pressure grooved roller 452 and the second pressing roller 453 on the pressure roller shaft 451. The first axial adjustment assembly 47 and the second axial adjustment assembly 48 have the same structure. This application will describe the first axial adjustment assembly 47 as an example.
[0040] refer to Figure 4 and Figure 5 The first axial adjustment assembly 47 includes multiple adjusting cylinders 471, a locking element 472, and a pressure sensor 473. The adjusting cylinders 471 are located on both sides of the extrusion roller 442 and are threadedly connected to the extrusion roller shaft 441. The pressure sensor 473 is fixedly connected to the adjusting cylinders 471 and abuts against the first pressing roller 443. When the positions of the extrusion roller 442 and the first pressing roller 443 need to be adjusted, the adjusting cylinders 471 are turned, causing them to move axially along the extrusion roller shaft 441, thereby pushing the extrusion roller 442 and the first pressing roller 443 to the target position along the axial direction of the extrusion roller shaft 441. The locking element 472 is a bolt, which passes through the adjusting cylinder 471 and is threadedly connected to it. After the positions of the extrusion roller 442 and the first pressing roller 443 are adjusted, the locking member 472 is turned so that the locking member 472 abuts against the extrusion roller shaft 441, and the locking member 472 locks the position of the adjusting cylinder 471 on the extrusion roller shaft 441.
[0041] refer to Figure 4and Figure 5 Since the first axial adjustment assembly 47 can adjust the positions of the extrusion roller 442 and the first pressing roller 443, and the second axial adjustment assembly 48 can adjust the positions of the pressure-receiving grooved roller 452 and the second pressing roller 453, it can adapt to the needs of coil workpieces of different widths and indentation positions. The pressure sensor 473 can detect the axial force on the extrusion roller 442 and the first pressing roller 443 in real time. When the extrusion roller 442 and the pressure-receiving grooved roller 452 wear down due to long-term use, the axial force state of the extrusion roller 442 and the pressure-receiving grooved roller 452 will change. The pressure sensor 473 can detect this change in time and provide feedback, prompting the operator to adjust the position of the extrusion roller 442 and the pressure-receiving grooved roller 452 or replace the worn parts, realizing online monitoring and preventive maintenance of wear status, improving the reliability and service life of equipment operation.
[0042] refer to Figure 3 and Figure 4 A pressing roller 44 and a pressure roller 45 form a pressing assembly. Multiple pressing assemblies are provided, with the pressing roller 44 and pressure roller 45 of adjacent pressing assemblies located on the same side of the coil workpiece. Specifically, for adjacent pressing assemblies, in one set, the pressing roller 44 is located above the coil workpiece, and the pressure roller 45 is located below the coil workpiece; in another set, the pressing roller 44 is located below the coil workpiece, and the pressure roller 45 is located above the coil workpiece. When the coil workpiece passes through multiple pressing assemblies, the multiple pressing assemblies alternately perform concave and convex processing on the same predetermined area of the coil workpiece. That is, the predetermined area of the coil workpiece alternately shows concave and convex marks. The alternating concave and convex processing causes repeated bending deformation in the predetermined area of the coil workpiece, leading to metal fatigue effect in the material of the predetermined area of the coil workpiece, reducing the shear strength and fracture toughness of the predetermined area of the coil workpiece. After being processed by multiple sets of extrusion components, the mechanical strength of the predetermined area of the coil workpiece decreases. The subsequent slitting mechanism 6 only needs to apply a small cutting force to cut off this area, which effectively improves the problems of difficulty in slitting thicker metal coils (metal coils greater than 0.5 mm) and equipment deformation and tool wear caused by excessive cutting force.
[0043] refer to Figure 2 and Figure 3 Multiple auxiliary tension rollers 46 are rotatably connected to the support frame 41. The auxiliary tension rollers 46 are located on both sides of the extrusion assembly. The coil workpiece passes through the auxiliary tension rollers 46, which can tension the coil workpiece, which is beneficial for the extrusion assembly to extrude indentations into the coil workpiece.
[0044] refer to Figure 1In this embodiment, multiple leveling rollers 5 are rotatably connected to the frame 1. After passing through the extrusion mechanism 4, the coiled material passes between the leveling rollers 5, which flatten the coiled material. After being processed by the extrusion mechanism 4, a predetermined area of the coiled material will have indentations or convexities. If it enters the slitting mechanism 6 directly without further processing, it may affect the stability of the slitting and the quality of the cross-section. By setting up the leveling rollers 5, the raised area around the indentations can be appropriately flattened, restoring the surface of the coiled material to a flat surface, which is beneficial for subsequent slitting.
[0045] refer to Figure 1 and Figure 6 The slitting mechanism 6 includes a cutter shaft 61, a circular cutter 62, and a slitting drive source 63. The cutter shaft 61 is rotatably connected to the frame 1, and the circular cutter 62 is fixedly connected to the cutter shaft 61. The slitting drive source 63 is specifically a motor, and its body is fixedly connected to the frame 1. The slitting drive source 63 drives the cutter shaft 61 to rotate. The coiled material workpiece, after being processed by the leveling roller 5, passes through the circular cutter 62. The circular cutter 62 cuts the indented area. Since the shear strength at the indentation area has been reduced, the circular cutter 62 can more easily cut the coiled material workpiece, forming a high-quality slitting surface with fewer burrs and less tool wear.
[0046] refer to Figure 1 The winding mechanism 7 is mounted on the frame 1 and is used to wind the slit narrow strip into coils. In this embodiment, two sets of conveying rollers 3, extrusion mechanism 4, leveling rollers 5, slitting mechanism 6, and winding mechanism 7 are provided. Unwinding mechanism 2 unwinds two coil workpieces. This application can process two coil workpieces simultaneously and finally wind them into two winding mechanisms 7 respectively, which can improve processing efficiency.
[0047] The implementation principle of a vertical slitting machine according to an embodiment of this application is as follows: First, the unwinding mechanism 2 unwinds the coiled workpiece, which is then guided and conveyed into the extrusion mechanism 4 by the conveying roller 3. The extrusion drive source 421 drives the slider 422 to slide, causing the extrusion roller 44 to approach the pressure roller 45. The pressure sensor 423 monitors the extrusion pressure in real time, ensuring that the extrusion pressure reaches a set value. The rotation drive source 43 drives the extrusion roller 44 and the pressure roller 45 to rotate, and the coiled workpiece passes between the extrusion roller 44 and the pressure roller 45. The flange of the extrusion roller 442 engages with the annular groove of the pressure roller 452, extruding an indentation in a predetermined area of the coiled workpiece. The first pressing roller 443 and the second pressing roller 453 clamp and press the two sides of the indentation to ensure the stability of the extrusion process. Multiple sets of extrusion components alternately perform concave and convex treatments on the same predetermined area of the coiled workpiece, causing metal fatigue in the predetermined area. After being extruded, the coiled material is flattened by the leveling roller 5 and then enters the slitting mechanism 6. The slitting mechanism 6 cuts the indented areas. Since the shear strength at the indentations has been reduced, the slitting process is smoother and the cross-sectional quality is better. Finally, the winding mechanism 7 winds up the narrow strip after slitting.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
