Description

Technical Field

[0001] This application relates to the technical field of flattening devices, and particularly to a silicon steel sheet flattening device. Background Art

[0002] Silicon steel sheets are a type of material widely used in the power industry and the electronics industry. Especially in the manufacturing of transformers and motors, the quality of silicon steel sheets directly affects the performance and energy consumption of the equipment. During the production and processing, silicon steel sheets may become uneven due to mechanical stress, thermal stress, and internal material defects. These unevennesses will affect subsequent coating, shearing, and laminating processes, thereby affecting the performance of the final product. Therefore, symmetrically arranged pressure rollers are usually used to flatten the silicon steel sheets. However, when the silicon steel sheets are flattened, they are prone to position deviation or warping due to the extrusion of the pressure rollers. Summary of the Utility Model

[0003] The problem to be solved by this application is that when the existing silicon steel sheets are flattened by symmetrically arranged pressure rollers, they are prone to position deviation or warping due to the extrusion of the pressure rollers.

[0004] To solve the above technical problems, this application provides a silicon steel sheet flattening device, which includes a frame for basic support. In the middle position of the upper part of the frame along the length direction, a roller pressing assembly for flattening the silicon steel sheets by roller pressing is arranged. On both sides of the roller pressing assembly, there are symmetrically arranged deviation rectifying assemblies for preventing deviation and limiting the position of the incoming and outgoing silicon steel sheets by rolling, and anti-warping assemblies for preventing warping and limiting the position of the incoming and outgoing silicon steel sheets by rolling.

[0005] Since the flattening device of this application is designed with a roller pressing assembly, a deviation rectifying assembly, and an anti-warping assembly, it can not only achieve the roller pressing and flattening operation of the silicon steel sheets through the roller pressing assembly, but also achieve the anti-deviation and anti-warping operations of the silicon steel sheets during roller pressing through the deviation rectifying assembly and the anti-warping assembly, solving the problem that when the existing silicon steel sheets are flattened by symmetrically arranged pressure rollers, they are prone to position deviation or warping due to the extrusion of the pressure rollers.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment

[0015] The present application relates to a silicon steel sheet flattening device. As Figure 1-7 shown, the flattening device includes a frame 4 for basic support. In the middle position of the upper part of the frame 4 in the length direction, a rolling component 1 for flattening the silicon steel sheet by rolling is arranged. In order to prevent the silicon steel sheet from shifting during rolling, therefore, deviation rectifying components 3 for anti-offset limiting operation of the incoming and outgoing silicon steel sheets by rolling are symmetrically arranged on both sides of the rolling component 1. In order to prevent the silicon steel sheet from warping during rolling, therefore, anti-warping components 2 for anti-warping limiting of the incoming and outgoing silicon steel sheets by rolling are symmetrically arranged on both sides of the rolling component 1.

[0016] The rolling component includes a roller frame 6, a motor 8 and a pressing roller. The roller frame 6 is fixedly arranged on the upper part of the frame 4 for suspended support. Two groups of pressing rollers for applying pressure to the upper and lower surfaces of the silicon steel sheet are symmetrically arranged on the upper part of the roller frame 6. The pressing rollers are divided into power rollers 7 and follow-up rollers 5 according to different motion forms. Thus, a certain pressure contact is formed between the power rollers 7 and the follow-up rollers 5 and the silicon steel sheet. Then, the rotation of the power roller 7 drives the silicon steel sheet to advance, and while the silicon steel sheet advances, it synchronously drives the follow-up roller 5 to rotate. A motor 8 for driving the rotation of the power roller 7 is also arranged on the upper part of the frame 4.

[0017] The deviation rectifying assembly 3 includes a wheel frame 13, a screw rod 16, a sleeve block 14, a guide rod 15, a support plate 11, and a roller 12. The wheel frame 13 is fixedly arranged on the upper part of the machine frame 4 for suspension and support. A support plate 11 perpendicular to the wheel frame 13 is arranged on the upper part of the wheel frame 13. A roller 12 for abutting against the side edge of the silicon steel sheet is arranged on the upper part of the support plate 11 to play a role in rectifying the deviation during movement. In order to adapt to silicon steel sheets of various width dimensions, a sleeve block 14 connected thereto is arranged below the support plate 11. A guide rod 15 slidably connected to the sleeve block 14 is arranged on the upper part of the wheel frame 13. A screw rod 16 threadedly connected to the sleeve block 14 is also arranged on the upper part of the wheel frame 13. By rotating the screw rod 16, the sleeve blocks 14 are driven to move in the same or opposite directions. The screw rod 16 is composed of a screw rod 16 with a right-handed thread and a screw rod 16 with a left-handed thread spliced together. Immediately, the sleeve block 14 will drive the support plate 11 to reciprocally slide along the guide rod 15, thereby changing the distance between the rollers 12 for abutting against the side edge of the silicon steel sheet, and then it can adapt to silicon steel sheets of various width dimensions.

[0018] The anti-warping assembly 2 includes a hanging plate 9 and a hanging roller 10. The hanging roller 10 is horizontally arranged at one end of the roller frame 6 for abutting against the silicon steel sheet. In order to adapt to silicon steel sheets of various thickness dimensions, both ends of the hanging roller 10 are connected to the roller frame 6 through rotatable hanging plates 9. Under normal conditions, the hanging roller 10 abuts against the silicon steel sheet by virtue of its own gravity and can generate sufficient pressure to prevent the silicon steel sheet from warping. Moreover, the hanging roller 10 can also rotate as the silicon steel sheet moves, greatly reducing the frictional force between the hanging roller 10 and the silicon steel sheet.

[0019] During use, according to the width of the silicon steel sheet, the screw rod 16 is rotated to drive the sleeve block 14 to adjust the distance in the same or opposite directions, so that the support plate 11 on the upper part of the sleeve block 14 can drive each roller 12 to adapt to the width of the silicon steel sheet. Immediately, the silicon steel sheet can pass through the position where the hanging roller 10 is located, and the anti-warping operation of the silicon steel sheet is realized under the gravity of the hanging roller 10. Then, the power roller 7 driven by the motor 8 drives the silicon steel sheet to perform a rolling operation between the power roller 7 and the follower roller 5, so that the silicon steel sheet can become flat after rolling. Thus, with the design of the roller 12, the silicon steel sheet will not shift in position during the rolling process, and the design of the hanging roller 10 makes the silicon steel sheet not warp during the rolling process.
