Description

Technical Field

[0001] This application relates to the technical field of cutting equipment, and more particularly to a cold-rolled coil cutting device. Background Technology

[0002] Cold-rolled coils are widely used in automobile manufacturing, home appliance production and other fields due to their advantages such as high surface smoothness and good dimensional accuracy.

[0003] After cold-rolled steel coils are processed, they need to be cut to the target length. Currently, the cutting process is mainly completed by cutting equipment, commonly using a hydraulic cylinder to drive the cutter during continuous coil feeding. However, due to the high yield strength and elastic modulus of cold-rolled steel coils, the sudden impact of the cutter on the sheet metal at the moment of cutting can easily cause localized springback deformation in the cutting area. Furthermore, during cutting, the conveying device continuously feeds the cold-rolled steel coil, and when the cutting end of the coil collides with the cutter, it can cause a "bulge" to form on the surface of the coil due to mutual compression. These "bulges" not only directly affect the finished quality of the cold-rolled steel coil, but also necessitate the addition of leveling or repair processes at the "bulge" in subsequent processing, increasing the number of processing steps and impacting production efficiency and cost control.

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The following describes a cold-rolled coil cutting device according to an embodiment of this application, with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown in the figure, a cold-rolled coil cutting device according to an embodiment of this application may include a support assembly 1, a feeding mechanism 2, a swinging mechanism 3, and a cutting mechanism 4.

[0021] It should be noted that the support component 1 described in the above embodiment is placed at the discharge end of the cold-rolled coil processing device (not shown in the figure).

[0022] The feeding mechanism 2 and the swing mechanism 3 are respectively mounted on the support assembly 1, and the swing mechanism 3 is connected to the feeding mechanism 2 in a transmission manner. The swing mechanism 3 may include a driving gear 31, a driven gear 32, a lifting assembly 33, a linkage assembly 34, and a swing assembly 35.

[0023] It should be noted that the swing mechanism 3 described in the above embodiment is provided in two sets and is located on both sides of the feeding mechanism 2.

[0024] Furthermore, in the above embodiment, a sliding plate is installed on the side of the driven gear 32 facing the feeding mechanism 2, and the feeding mechanism 2 is provided with a sliding groove for the sliding plate to slide, thereby limiting the sliding path of the driven gear 32 during the sliding process.

[0025] The drive gear 31 and the driven gear 32 are both mounted on the feeding mechanism 2. The drive gear 31 is connected to the feeding mechanism 2 in a transmission manner. The lifting component 33 is mounted on the feeding mechanism 2, and the extended end of the lifting component 33 is connected to the driven gear 32. The swing component 35 is mounted on the support component 1, and the driven gear 32 is connected to the swing component 35 in a transmission manner through the linkage component 34.

[0026] It is understandable that after the drive gear 31 is driven by the feeding mechanism 2, the driven gear 32 meshes with the drive gear 31 through the lifting component 33, thereby driving the swing component 35 through the linkage component 34, and completing the movement of the cutting mechanism 4 during the driving process, thereby achieving the effect of dynamic cutting of cold rolled coil.

[0027] The swing assembly 35 may include a slider 351, a swing arm 352, and a mounting platform 353.

[0028] It should be noted that the swing component 35 described in the above embodiment is provided in two sets, and the two sets of swing components 35 are respectively provided on both sides of the feeding mechanism 2.

[0029] The slider 351 is mounted on the support assembly 1, the swing arm 352 is mounted on the slider 351, the mounting platform 353 is slidably mounted on the support assembly 1, and one end of the swing arm 352 is hinged to the mounting platform 353.

[0030] Understandably, after the slider 351 is driven by the linkage component 34, the swing arm 352 pushes the mounting table 353 and the cutting mechanism 4 forward, and realizes dynamic cutting of the cold-rolled coil during the movement.

[0031] Furthermore, such as Figure 3 and Figure 4 As shown, the lifting assembly 33 may include a cylinder 331, a connecting plate 332, and a connecting rod 333.

[0032] It should be noted that the connecting rod 333 described in the above embodiment is rotatable with the driven gear 32, thereby avoiding any impact on the rotation of the driven gear 32.

[0033] The cylinder 331 is mounted on the feeding mechanism 2, and the connecting plate 332 is mounted on the extended end of the cylinder 331. The connecting plate 332 is connected to the driven gear 32 through the connecting rod 333.

[0034] Understandably, driven by cylinder 331, the height of driven gear 32 is adjusted by connecting plate 332 and connecting rod 333, thereby achieving meshing between driven gear 32 and driving gear 31.

[0035] Specifically, such as Figure 3 and Figure 4As shown, the linkage assembly 34 may include a drive sprocket 341, a chain 342, a driven sprocket 343, and a transmission rod 344.

[0036] The driving sprocket 341 is mounted on the driven gear 32, the transmission rod 344 is connected to the swing arm 352, the driven sprocket 343 is mounted on the transmission rod 344, and the driving sprocket 341 and the driven sprocket 343 are connected by a chain 342.

[0037] Understandably, under the action of chain 342, the driving sprocket 341 and the driven sprocket 343 start to rotate, and when the driven sprocket 343 rotates, the swing arm 352 is swung through the transmission rod 344, thereby driving the cutting mechanism 4 forward.

[0038] It should be noted that a geared motor and gears can be installed on the feeding mechanism 2. After the cutting is completed, the cylinder 331 drives the driven gear 32 to descend and mesh with the gear, thereby driving the swing component 35 to reset under the action of the geared motor and gears, so as to realize the cutting of the next set of cold-rolled coils.

[0039] The cutting mechanism 4 is mounted on the mounting platform 353.

[0040] Understandably, the cutting mechanism 4 is used to cut the cold-rolled coil.

[0041] Furthermore, such as Figure 5 As shown, the cutting mechanism 4 may include a support frame 41, a cutting assembly 42, and an auxiliary plate 43.

[0042] The support frame 41 is mounted on the mounting platform 353, and the cutting assembly 42 and the auxiliary plate 43 are both mounted on the support frame 41.

[0043] Understandably, the installation of the cutting assembly 42 and the auxiliary plate 43 is completed under the action of the support frame 41, and the cold-rolled coil is supported under the action of the auxiliary plate 43. Then, the cold-rolled coil is cut by the cutting assembly 42.

[0044] Specifically, such as Figure 5 As shown, the cutting assembly 42 may include a hydraulic cylinder 421, a fixing plate 422, a retraction frame 423, an abutment plate 424, and a cutter 425.

[0045] It should be noted that the retractable frame 423 described in the above embodiment is provided in two sets, and the retractable frame 423 is composed of a slide and a spring.

[0046] Hydraulic cylinder 421 is mounted on support frame 41, fixed plate 422 is mounted on the extended end of hydraulic cylinder 421, retractable frame 423 is mounted on fixed plate 422, abutment plate 424 is slidably mounted on fixed plate 422, abutment plate 424 passes through fixed plate 422 and is slidably connected to retractable frame 423, and cutter 425 is mounted on the extended end of hydraulic cylinder 421.

[0047] Specifically, when the extended end of the hydraulic cylinder 421 descends, it drives the fixed plate 422 to descend as well. Then, the cold-rolled coil is abutted by the shrinking frame 423 and the abutting plate 424. As the extended end of the hydraulic cylinder 421 continues to descend, the shrinking frame 423 retracts to avoid affecting the cutting work of the cutter 425. Finally, the cutting work of the cold-rolled coil is completed under the action of the cutter 425.

[0048] The above-described embodiments enable stable cooperation between the cutting tool and the cold-rolled steel coil during the cutting process, effectively preventing deformation in the cutting area; at the same time, they prevent bulging of the cold-rolled steel coil due to collision and squeezing with the cutting tool during the conveying process.

[0049] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the support assembly 1 may include a support platform 11, a placement roller 12, and a take-up roller 13.

[0050] It should be noted that both the placement roller 12 and the take-up roller 13 described in the above embodiments are driven by motors.

[0051] The placement roller 12 and the take-up roller 13 are both mounted on the support platform 11, and the placement roller 12 and the take-up roller 13 are arranged opposite to each other.

[0052] It should be noted that the winding roll 13 described in the above embodiment is equipped with an elastic abutment roll (not shown in the figure), so as to realize the real-time abutment and fixation of the cold rolled roll after winding during the winding process, and avoid the loosening after cutting.

[0053] In one embodiment of this application, such as Figures 1-3 As shown, the feeding mechanism 2 may include a mounting frame 21 and a feeding assembly 22.

[0054] It should be noted that the mounting bracket 21 described in the above embodiments is provided in two sets.

[0055] The mounting frame 21 is mounted on the support platform 11, and the feeding assembly 22 is mounted on the mounting frame 21.

[0056] Understandably, the installation of the feeding assembly 22 is completed under the action of the mounting frame 21, and the auxiliary conveying of the cold-rolled coil is realized under the action of the feeding assembly 22.

[0057] Specifically, such as Figures 1-3 As shown, the feeding assembly 22 may include a drive motor 221, a first conveying roller 222, and a second conveying roller 223.

[0058] The drive motor 221 is mounted on the mounting frame 21, and the first conveying roller 222 and the second conveying roller 223 are both rotatably mounted on the mounting frame 21. The output end of the drive motor 221 passes through the mounting frame 21 and is connected to the first conveying roller 222 in a transmission connection.

[0059] Specifically, driven by the drive motor 221, the first conveying roller 222 is rotated. When the first conveying roller 222 conveys the cold-rolled coil, it simultaneously drives the second conveying roller 223 to rotate, thereby realizing the conveying of the cold-rolled coil.

[0060] Specifically, the cold-rolled coil cutting equipment provided in this application can be used to cut cold-rolled coils. In actual operation, the personnel first place the cold-rolled coil on the placement roller 12 of the support assembly 1, and the cold-rolled coil passes through the feeding mechanism 2. The drive motor 221 of the feeding mechanism 2 starts, driving the first conveying roller 222 and the second conveying roller 223 to rotate, thereby realizing the conveying of the cold-rolled coil. During the conveying process, the swing mechanism 3 begins to function.

[0061] The cylinder 331 of the lifting assembly 33 is activated, adjusting the height of the driven gear 32 via the connecting plate 332 and the connecting rod 333, causing the driven gear 32 to mesh with the driving gear 31. The driving gear 31 is driven to rotate by the feeding mechanism 2, which in turn drives the driven gear 32 to rotate. The driving sprocket 341 on the driven gear 32 rotates accordingly, driving the driven sprocket 343 to rotate via the chain 342. The driven sprocket 343 causes the swing arm 352 of the swing assembly 35 to swing via the transmission rod 344. The swing arm 352 pushes the mounting platform 353 to slide forward on the support assembly 1, and the cutting mechanism 4 on the mounting platform 353 also moves forward accordingly.

[0062] When the cutting mechanism 4 moves along with the cold-rolled coil, the cutting assembly 42 begins to operate. The extended end of the hydraulic cylinder 421 descends, causing the fixing plate 422 to descend as well. The abutment plate 424 first contacts the cold-rolled coil during the descent of the fixing plate 422. As the extended end of the hydraulic cylinder 421 continues to descend, the retraction frame 423 retracts to avoid affecting the cutting operation of the cutter 425. Finally, the cutter 425 descends to complete the cutting of the cold-rolled coil. After the cutting is completed, because the abutment plate 424 is in contact with the cold-rolled coil, the cold-rolled coil is prevented from sagging after cutting. At the same time, when the hydraulic cylinder 421 rises, the feeding mechanism 2 continuously conveys the cold-rolled coil.

[0063] After cutting, the cylinder 331 of the lifting assembly 33 drives the driven gear 32 to descend, engaging with the reduction motor and gear mounted on the feeding mechanism 2. Under the action of the reduction motor and gear, the swing assembly 35 resets, preparing for the cutting of the next set of cold-rolled coils. Throughout the cutting process, because the cutting mechanism 4 can move synchronously with the cold-rolled coil, deformation of the cutting area is effectively avoided, preventing bulging of the cold-rolled steel coil due to collision and squeezing with the cutter during transport, thus improving the cutting quality and production efficiency of the cold-rolled coil. At the same time, the dynamic cutting method reduces the brief pauses caused by the cutter contacting the cold-rolled coil during the cutting process, further improving the cutting effect. Throughout the operation, relevant personnel need to closely monitor the operating status of the equipment, promptly handle any abnormalities, and ensure the stable operation of the equipment and the smooth progress of the cutting work.

[0064] In summary, the cold-rolled coil cutting equipment of this application embodiment can achieve stable cooperation between the cutting tool and the cold-rolled steel coil during the cutting process, effectively avoiding deformation in the cutting area; at the same time, it prevents the cold-rolled steel coil from bulging due to collision and squeezing with the cutting tool during the conveying process.
