[0004] The punching machine is also called cutting equipment or CNC stamping equipment. During the processing of coils, it is generally necessary to process some functional units (such as through holes) at equal intervals in the length direction of the coil. These functional units are generally processed by die-cutting equipment.

As a result, the tension of the coil is easily uneven during the continuous loading process, resulting in the coil twisting or wrinkling, causing problems such as high scrap rate and high production cost.

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Specific embodiment, combined with Figures 1 to 4 The figure further illustrates the technical solution of the present invention, which includes a loading frame for adjusting the tension of a coil, comprising a loading mechanism 10 for clamping the coil for loading, and a tension adjustment mechanism 20 for adjusting the tension of the coil during loading. The tension adjustment mechanism 20 includes a floating roller 21 for stretching the coil to smoothly unfold it, and an adjusting roller 22 that can be moved up and down to adjust the tension of the coil. By adjusting the adjusting roller 22 up and down, the loading frame can flexibly adjust the tension of the coil, ensuring that the coil remains balanced throughout the loading process, ensuring uniform tension of the coil, and preventing twisting or wrinkling of the coil, thereby reducing scrap rates and lowering production costs.

[0033] Furthermore, as a preferred embodiment of the present invention but not a limitation, the tension adjustment mechanism 20 also includes an installation component 23 for installing the floating roller 21 and the adjusting roller 22, and one installation component 23 is provided at each end of the floating roller 21 and the adjusting roller 22, and a control component 24 for controlling the movement of the adjusting roller 22 is provided on the installation component 23.

[0034] In this embodiment, the staff can adjust the position of the adjusting roller through the control component according to different coil specifications or production requirements, so as to ensure the tension balance of the coil, thereby ensuring the quality of the product, and the operation is simple and convenient; the design of the installation component can make the floating roller and the adjusting roller more compactly arranged, saving space.

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the control component 24 includes a screw 241 and an adjusting member 242 connected to the screw 241 and controlled by the screw 241 for driving the adjusting roller 22 to move. A fixing member 243 is provided between the screw 241 and the adjusting member 242 so that the adjustment position of the adjusting roller 22 can be fixed.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation, a groove 2421 for fixedly connecting to the screw 241 is provided in the middle of the top of the adjusting member 242, and a through hole 2422 is opened in the middle of the adjusting member 242. The size of the through hole 2422 matches the adjusting roller 22, so that the adjusting roller 22 can be fastened and installed on the adjusting member 242 through the through hole 2422.

[0037] In this embodiment, the position of the adjusting roller is precisely adjusted by driving the adjusting member through a screw, which has high positioning accuracy, so that the tension of the coil can be precisely adjusted to ensure the balance of the coil tension. At the same time, the screw drive can provide stable thrust and pull, which helps to maintain the adjusted position of the adjusting roller; the design of the fixing member can ensure that the adjusting roller is locked in the adjusted position to avoid deviation or loosening during the operation of the equipment, thereby maintaining long-term stability and ensuring product quality.

[0038] Furthermore, as a preferred embodiment of this solution but not a limitation, the mounting assembly 23 includes a first guide rail 231 for movement of the adjusting member 242. The first guide rail 231 is provided on each of the left and right sides of the adjusting member 242. A fastener 232 for fixing the dancer roller 21 is provided on the outer side of the first guide rail 231 near the coil feeding side. A connecting bar 233 is connected to the top of the two first guide rails 231. The connecting bar 233 and the two first guide rails 231 constitute a moving space for the adjusting member 242. A threaded hole 234 is provided in the middle of the connecting bar 233.

[0039] The screw rod 241 is used to adjust the position of the adjusting member 242 up and down through the threaded hole 234 .

[0040] In this embodiment, the design of the first guide rail can ensure that the adjusting member can move along a predetermined straight path, avoiding offset and deviation when the adjusting member moves, thereby improving the adjustment accuracy of the tension of the roll. In addition, the first guide rail can significantly reduce the friction between the transmission components, making the movement and adjustment of the adjusting member smoother; the moving space formed by the first guide rail and the connecting strip reduces the vibration and shaking caused by the movement of the adjusting member, so that the adjusting member can move and adjust more stably, which is conducive to ensuring the adjustment of the tension of the roll.

[0041] Furthermore, as a preferred embodiment of the present invention but not limiting, the feeding mechanism 10 includes a clamping arm 101 provided at the left and right ends for clamping the coiled material drum, and a first driving device 102 for driving the clamping arms 101 at both ends to lift and feed the material when the clamping arms 101 at the left and right ends clamp the coiled material drum. The front portion of the clamping arms 101 at both ends is provided with a conical head assembly 103 for clamping into the axial center hole of the coiled material drum. The first driving device 102 is a hydraulic device or a driving motor. In this embodiment, the first driving device 102 is a hydraulic device.

[0042] The conical head assembly 103 includes a first conical head assembly 1031 and a second conical head assembly 1032. The radius of the first conical head assembly 1031 is smaller than the radius of the second conical head assembly 1032. The surfaces of the first conical head assembly 1031 and the second conical head assembly 1032 are both provided with a plurality of protrusions 1033 for enhancing friction with the inner wall of the axial hole of the coiled material drum. The density of the protrusions 1033 on the surface of the first conical head assembly 1031 is smaller than the density of the protrusions 1033 on the surface of the second conical head assembly 1032.

[0043] In addition, one first driving device 102 is provided at each end of the clamping arms 101 .

[0044] In this embodiment, the protrusions on the surface of the conical head assembly increase the friction with the inner wall of the axial hole of the coil drum, preventing the coil drum from slipping or loosening during rotation, thereby ensuring the stability and reliability of the coil drum when loading materials; the radius of the first conical head assembly is small and the density of protrusions on the surface is low, which helps to reduce damage to the inner wall of the coil drum and avoid damage to thinner or fragile coils.

[0045] Furthermore, as a preferred embodiment of the present invention but not limiting, the feeding mechanism 10 further includes a second guide rail 104 for horizontally moving the clamping arm 101 and a second driving device 105 for driving the clamping arms 101 at both ends to move horizontally. The second driving device 105 is a hydraulic device or a driving motor. In this embodiment, the second driving device 105 is a hydraulic device.

[0046] Among them, the second driving device 105 can control the horizontal movement of the clamping arms 101 at both ends according to the specifications of the coiled material drum, so as to adaptively adjust the distance between the two conical head assemblies 103. In addition, the horizontal movement of the clamping arms 101 at both ends can also be controlled synchronously. In short, the specific operation should be based on the actual specifications of the coiled material drum to control the horizontal movement of the clamping arms 101.

[0047] In this embodiment, the second driving device drives the clamping arm to move toward the middle to clamp the coiled material tube. The entire process is automated, which reduces the labor intensity of the operator and improves work efficiency.

[0048] The working principle of this embodiment is as follows:

[0049] The present invention proposes a loading rack for adjusting the tension and relaxation of a coiled material. The tension and relaxation of the coiled material is adjusted by adjusting the position of an adjusting roller 22 up and down. The specific principle is as follows:

[0050] The coil is placed in front of the loading mechanism 10 by a forklift or manually, and the second driving device 105 of the loading mechanism 10 controls the clamping arms 101 at the left and right ends to move toward the middle. When the conical head assembly 103 of the clamping arm 101 is engaged with the axial center hole of the coil to clamp the coil, the first driving device 102 controls the clamping arms 101 at the left and right ends to lift up and load the material. The coil is smoothly unrolled by the floating roller 21. If the tension of the coil is relatively loose, the adjusting member 242 can be driven by the adjusting screw 241 to lift the adjusting roller 22 upward, so that a certain height difference is formed between the adjusting roller 22 and the floating roller 21, thereby increasing the tension of the coil to meet the tension requirement. Similarly, when the tension of the coil is relatively tight, the adjusting roller 22 can be adjusted downward to reduce the tension of the coil.

[0051] In addition, the position of the adjusting roller 22 can also be adjusted according to actual tension requirements.

[0052] In this embodiment, a punching machine is also provided, which includes a loading frame that can adjust the tension of the coil as described above, the loading frame is connected to a tensioning mechanism 30 for tensioning the coil, and the tensioning mechanism 30 is connected to a conveying mechanism 40 on the discharge side for conveying the coil to the punching mechanism for punching.

Furthermore, due to differences in industry nomenclature, the present invention is not limited to the above nomenclature, nor is it limited to English nomenclature.
