Description

Technical Field

[0001] The present application relates to the technical field of slitting machines, and in particular to a feeding and pressing device for slitting and cutting silicon steel coils. Background Art

[0002] Strip cutting is a crucial step in the processing of silicon steel coils, and the infeed clamping device is a key piece of equipment for ensuring cutting quality and efficiency. Existing infeed clamping devices for strip cutting of silicon steel coils primarily consist of a fixed pressure plate, a movable pressure plate, mounting brackets, and a drive mechanism. Two mounting brackets are symmetrically fixed to the lower end of the fixed pressure plate, while the drive mechanism is mounted on the fixed bracket and drives the movable pressure plate to move relative to the fixed pressure plate, thereby compressing and releasing the silicon steel coil.

[0003] To reduce wear between the silicon steel coil and the pressure plate, both the fixed and movable pressure plates are fixedly connected with anti-wear pads on the ends that come into contact with the silicon steel coil. This design extends the service life of the pressure plate to a certain extent while also protecting the surface quality of the silicon steel coil.

[0004] However, in practice, due to the integrated connection between the anti-wear pad and the pressure plate, when the anti-wear pad becomes excessively worn after a period of use, replacing it becomes quite cumbersome and difficult. This not only increases maintenance costs but can also affect production efficiency and product quality due to untimely replacement.

[0005] Therefore, the present application provides a material feeding and pressing device for cutting silicon steel coils into strips to solve the above problems. Utility Model Content

[0006] The present application provides a feeding and pressing device for slitting silicon steel coils, which aims to solve the problem proposed in the background technology that the existing anti-wear pad and the pressure plate adopt an integrated connection method. When the anti-wear pad is excessively worn after a period of use, its replacement process becomes quite cumbersome and difficult.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a feeding and clamping device for slitting silicon steel coils, comprising a fixed pressing plate, a mounting bracket symmetrically fixedly arranged on the fixed pressing plate, a movable pressing plate arranged on an end of the fixed pressing plate away from the mounting bracket, anti-wear pads respectively arranged on opposite ends of the fixed pressing plate and the movable pressing plate, and a driving structure symmetrically arranged at both ends of the fixed pressing plate and connected to the mounting bracket for driving the movable pressing plate to move closer to or away from the fixed pressing plate;

[0008] To install or replace the wear pads on the fixed and movable pressure plates, each is equipped with a fixing structure for securing the wear pads. The fixing structure includes two symmetrically arranged clamping plates, a first bolt inserted between the clamping plates and the fixed pressure plate, and a nut threaded onto the first bolt. The ends of the wear pad are located between the clamping plates and the fixed pressure plate. To replace the wear pad, first use a wrench to unscrew the nut, then pull out the first bolt, allowing the wear pad to be easily removed. To install a new wear pad, first insert the first bolt through one of the clamping plates, then thread one end of the wear pad onto the first bolt. Next, insert the first bolt through the pre-recorded hole in the fixed or movable pressure plate, then thread the other end of the wear pad onto the first bolt. Then, insert the other clamping plate onto the first bolt, and finally, use a wrench to tighten the nut onto the first bolt until it is secure. The wear pad is now securely fixed to the fixed or movable pressure plate. The wear pad is easy to install and remove, making it convenient to replace.

[0009] Preferably, in order to improve the bite force of the splint on the anti-wear pad: a tooth groove is provided on the side of the splint close to the fixed pressure plate. By providing the tooth groove, the bite force of the splint on the anti-wear pad is significantly improved, ensuring the stability and reliability of the anti-wear pad during the pressing process.

[0010] Preferably, the clamping plate, the fixed pressure plate, the movable pressure plate, and the anti-wear pad are each provided with corresponding first through-holes for inserting the first bolt. By providing corresponding first through-holes in each component and connecting them with the first bolt, the connection stability between the components is significantly improved, ensuring the overall stability and reliability of the clamping device.

[0011] Preferably, to facilitate the connection between the mounting bracket and the fixed pressure plate, the mounting bracket is fixedly mounted on the end of the fixed pressure plate away from the movable pressure plate by a second bolt. The second bolt connection makes the removal and reinstallation of the mounting bracket easier and faster, thereby reducing maintenance costs.

[0012] Preferably, to facilitate installation of the mounting bracket, a second through hole is provided on the mounting bracket. The provision of the second through hole makes insertion of the second bolt simpler and faster. By pre-providing the second through hole, accurate insertion and fixation of the second bolt can be ensured, thereby improving installation accuracy and reliability.

[0013] Preferably, the drive structure includes a guide frame fixedly mounted on the mounting bracket, a lifting block slidably disposed within the guide frame and fixedly connected to the movable pressure plate, and a cylinder fixedly mounted on the guide frame at one end away from the mounting bracket, with the output end of the cylinder extending through the guide frame and fixedly connected to the lifting block. The coordinated design of the guide frame and lifting block ensures smooth movement of the movable pressure plate during lifting, reduces vibration and noise, and improves the stability and reliability of the equipment.

[0014] Preferably, to facilitate the connection between the movable pressure plate and the lifting block, the lifting block is fixedly connected to the movable pressure plate via a third bolt. By adopting the third bolt connection, the connection between the lifting block and the movable pressure plate is more stable and reliable, and the third bolt connection method makes it easier and faster to remove and reinstall the lifting block and the movable pressure plate.

[0015] This application utilizes bolts and nuts to secure the anti-wear pad, making it easy and quick to install and remove, significantly improving replacement efficiency and reducing maintenance costs. Timely replacement of the anti-wear pad prevents damage to the pressure plate due to excessive wear, thereby extending the service life of the entire clamping device. Good contact and timely replacement of the anti-wear pad ensure stability and precision during the cutting process of the silicon steel coil, improving product quality.

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] This embodiment provides a material feeding and pressing device for cutting silicon steel coil into strips, such as Figure 1-3 As shown, the pressing device includes a fixed pressing plate 1, a mounting bracket 2 symmetrically fixed on the fixed pressing plate 1, a movable pressing plate 3 provided on one end of the fixed pressing plate 1 away from the mounting bracket 2, anti-wear pads 4 respectively provided on opposite ends of the fixed pressing plate 1 and the movable pressing plate 3, and a driving structure 5 symmetrically provided at both ends of the fixed pressing plate 1 and connected to the mounting bracket 2 for driving the movable pressing plate 3 to move closer to or away from the fixed pressing plate 1;

[0023] To install or remove the wear pads 4 on the fixed and movable pressure plates 1 and 3, a fixing structure 6 is provided on each plate. The fixing structure 6 comprises clamping plates 61 symmetrically arranged on either side of the fixed pressure plate 1, a first bolt 62 inserted into the clamping plates 61 and the fixed pressure plate 1, and a nut 63 threaded onto the first bolt 62. The ends of the wear pad 4 are located between the clamping plates 61 and the fixed pressure plate 1. The use of bolts and nuts 63 for fixing the wear pads 4 makes installation and removal of the wear pads 4 simple and quick, significantly improving replacement efficiency and reducing maintenance costs. Timely replacement of the wear pads 4 prevents damage to the pressure plates due to excessive wear, thereby extending the service life of the entire clamping device. Good contact and timely replacement of the wear pads 4 ensure stability and precision during the cutting process of the silicon steel coil, improving product quality. To replace the wear pads 4, first use a wrench to loosen the nuts 63, then remove the first bolt 62. The wear pads 4 can then be easily removed. When installing a new anti-wear pad 4, first insert the first bolt 62 through one of the clamping plates 61. Then, thread one end of the anti-wear pad 4 onto the first bolt 62. Next, thread the first bolt 62 through the reserved hole in the fixed pressure plate 1 or the movable pressure plate 3. Finally, thread the other end of the anti-wear pad 4 onto the first bolt 62. Then, fit the other clamping plate 61 onto the first bolt 62. Finally, use a wrench to tighten the nut 63 onto the first bolt 62 until it is securely fastened. In this way, the anti-wear pad 4 is securely fixed to the fixed pressure plate 1 or the movable pressure plate 3. The anti-wear pad 4 is easy to assemble and disassemble, making it convenient for replacement.

[0024] Furthermore, to enhance the grip of the clamping plate 61 on the anti-wear pad 4, a tooth groove 611 is provided on the side of the clamping plate 61 adjacent to the fixed pressure plate 1. This significantly enhances the grip of the clamping plate 61 on the anti-wear pad 4, ensuring the stability and reliability of the anti-wear pad 4 during the compression process. The tooth groove 611 increases the friction between the clamping plate 61 and the anti-wear pad 4, effectively preventing the anti-wear pad 4 from slipping or falling off during the compression process.

[0025] Specifically, the clamping plate 61, the fixed plate 1, the movable plate 3, and the anti-wear pad 4 all have corresponding first through-holes 7 for inserting the first bolt 62. By providing corresponding first through-holes 7 on each component and connecting them using the first bolts 62, the connection stability between the components is significantly improved, ensuring the overall stability and reliability of the clamping device. The provision of the first through-holes 7 makes inserting the first bolt 62 easier and faster, reducing installation difficulty and cost. When installing the anti-wear pad 4, first place the clamping plate 61 in the corresponding position of the fixed plate 1 or the movable plate 3, ensuring that the first through-hole 7 on the clamping plate 61 is aligned with the first through-hole 7 on the fixed plate 1 or the movable plate 3. Then, insert the first bolt 62 through the clamping plate 61 and the first through-holes 7 on the fixed plate 1 or the movable plate 3, and slide one end of the anti-wear pad 4 over the first bolt 62. Next, insert the first bolt 62 further through the first through-hole 7 on the anti-wear pad 4, and slide the other clamping plate 61 over the first bolt 62, so that it is opposite the first clamping plate 61. Finally, use a wrench to tighten the nut 63 onto the first bolt 62 until it is secure. This secures the wear pad 4 to the fixed platen 1 or movable platen 3. To replace the wear pad 4, simply follow the reverse process. First, use a wrench to loosen the nut 63, then remove the first bolt 62. The wear pad 4 and clamping plate 61 can now be easily removed. Then, reinstall the new wear pad 4 and clamping plate 61 according to the above installation steps.

[0026] Specifically, to facilitate the connection between the mounting bracket 2 and the fixed platen 1, the mounting bracket 2 is secured to the end of the fixed platen 1 away from the movable platen 3 using a second bolt. This second bolt connection provides a more stable and reliable connection between the mounting bracket 2 and the fixed platen 1, capable of withstanding greater workloads. This second bolt connection simplifies and speeds up the removal and reinstallation of the mounting bracket 2, reducing maintenance costs. This connection method can adapt to different working environments and requirements, facilitating adjustment and optimization of the clamping device.

[0027] More specifically, to facilitate installation of the mounting bracket 2, a second through hole 21 is provided on the mounting bracket 2. The provision of the second through hole 21 makes insertion of the second bolt easier and faster. By pre-providing the second through hole 21, accurate insertion and fixation of the second bolt can be ensured, thereby improving installation accuracy and reliability.

[0028] Specifically, the drive mechanism 5 includes a guide frame 51 fixedly mounted on the mounting bracket 2, a lifting block 52 slidably disposed within the guide frame 51 and fixedly connected to the movable pressure plate 3, and a cylinder 53 fixedly mounted on the end of the guide frame 51 away from the mounting bracket 2. The output end of the cylinder 53 extends through the guide frame 51 and is fixedly connected to the lifting block 52. The coordinated design of the guide frame 51 and the lifting block 52 ensures the smooth movement of the movable pressure plate 3 during the lifting process, reduces vibration and noise, and improves the stability and reliability of the equipment. When the silicon steel coil needs to be compressed, the cylinder 53 starts to operate, its output end extends and pushes the lifting block 52 to slide downward within the guide frame 51. The sliding of the lifting block 52 drives the movable pressure plate 3, to which it is fixed, to descend together until the gap between the movable pressure plate 3 and the fixed pressure plate 1 is small enough to clamp the silicon steel coil. At this time, the output end of the cylinder 53 remains extended, providing continuous compressive force to the movable pressure plate 3. When the silicon steel coil needs to be released, the output end of the cylinder 53 begins to retract, and the lifting block 52 slides upward within the guide frame 51, driving the movable pressure plate 3 upward with it. As the gap between the movable pressure plate 3 and the fixed pressure plate 1 gradually increases, the silicon steel coil is released. By controlling the extension and retraction of the cylinder 53, the lifting and lowering movement of the movable pressure plate 3 can be precisely controlled, thus meeting the compression and release requirements during the silicon steel coil slitting process.

[0029] More specifically, to facilitate the connection between the movable pressure plate 3 and the lifting block 52, the lifting block 52 is fixedly connected to the movable pressure plate 3 via a third bolt. This third bolt connection provides a more stable and reliable connection between the lifting block 52 and the movable pressure plate 3, and also makes disassembly and reassembly of the lifting block 52 and the movable pressure plate 3 much simpler and faster.

[0030] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
