Description

Technical Field

[0001] The utility model relates to the technical field of silicon steel sheet longitudinal shearing, in particular to a silicon steel sheet longitudinal shearing blank pressing device. Background Art

[0002] Silicon steel sheet is a special magnetic material, mainly used for manufacturing core components of power equipment such as motors, transformers and generators. It is composed of high-silicon iron and a small amount of elements such as carbon, silicon, and manganese. The silicon steel sheet longitudinal shearing machine is a special equipment for processing silicon steel sheets. Its function is to longitudinally cut silicon steel sheets to meet specific size or shape requirements. It can provide key materials for manufacturing efficient and energy-saving electrical equipment and plays a crucial role in optimizing the performance of equipment such as motors and transformers.

[0003] After retrieval, a silicon steel sheet longitudinal shearing blank pressing device with the publication number of CN218555764U includes a distance-adjusting support and a pressing member. The pressing points on the same pressing member include elastic pressing points and rigid pressing points. Corresponding pressing structures are provided for both the elastic pressing points and the rigid pressing points. When the pressing member moves downward to press the silicon steel strip material, the elastic pressing action of the elastic pressing points occurs first, and the rigid pressing action of the rigid pressing points occurs later. This solution realizes the prior elastic buffer downward pressure and then rigid downward pressure on the silicon steel strip material through the elastic pressing structure and the rigid pressing structure of the pressing member, and solves the problems of indentation and deformation caused by the direct rigid downward pressure of the silicon steel strip material by the plate body. However, when the above technical solution is actually used, there are still the following deficiencies:

[0004] This prior art enables the silicon steel sheet to be pressed before shearing through the setting of the pressing member, thereby maintaining the straightness of the silicon steel sheet during shearing. However, in this solution, the pressure distribution applied by the multiple pressing points on the pressing member in the width direction of the silicon steel sheet is uneven. Due to the small contact area, some areas may bear higher pressure, while other areas bear lower pressure. This uneven pressure distribution may cause local deformation of the silicon steel sheet during the pressing process, affecting its accuracy and processing quality. Secondly, during the transmission of the silicon steel sheet, due to the contact between the pressing points and it, a large frictional force will be generated between the two. This frictional force may not only cause wear on the surface of the silicon steel sheet, but also affect its surface smoothness and flatness. Especially for silicon steel sheets with high-precision requirements, surface wear will directly affect its electromagnetic characteristics and overall performance, thereby reducing its service efficiency and life in electrical equipment such as motors and transformers.

[0005] Therefore, it is necessary to design a silicon steel sheet longitudinal shearing blank pressing device to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to solve the deficiencies existing in the prior art, and a longitudinal shearing and material pressing device for silicon steel sheets is proposed.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

An airbag two is fixed between the upper surface of the sliding plate and the inner top surface of the control box. An airbag one is jointly fixed between the lower surface of the sliding plate and the inner bottom surface of the control box. A connecting pipe is communicated with the airbag one, and the connecting pipe is communicated with the inside of the airbag two. A plurality of connecting rods are fixed to the lower surface of the sliding plate.

[0011] As a preferred technical solution of the present utility model, fluids are provided inside the airbag one, airbag two and airbag three, and the fluids are electrorheological fluids.

[0012] As a preferred technical solution of the present utility model, the rollers located on the same connecting frame are arranged at equal intervals.

[0014] The present utility model has the following beneficial effects:

[0015] 1. Maintain the straightness and flatness of the silicon steel sheet: By using the linkage of the cylinder, roller, and control box, the silicon steel sheet is effectively pressed. The length of the roller matches the width of the silicon steel sheet to ensure that the applied force is evenly distributed on the surface of the silicon steel sheet, thereby preventing deformation of the silicon steel sheet during processing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1-3, A longitudinal shearing and pressing device for silicon steel sheets, comprising two mounting brackets 1 fixedly installed on a longitudinal shearing machine for silicon steel sheets, and the two mounting brackets 1 are symmetrically arranged up and down. A connecting frame 2 is provided inside the mounting bracket 1. At the bottom end position inside the connecting frame 2, a number of rollers 3 are rotatably connected. The length of the rollers 3 is the same as the width of the longitudinal shearing machine for silicon steel sheets. In this way, silicon steel sheets adapted to the size of the longitudinal shearing machine can all be adapted to the rollers 3, that is, along the width direction of the silicon steel sheet, the force exerted by the rollers 3 on the silicon steel sheet is evenly dispersed, which can prevent the silicon steel sheet from deforming due to uneven force. At the same time, due to the pressing effect of the rollers 3 on the silicon steel sheet, a rubber sleeve is fixedly sleeved on the rollers 3. When the rollers 3 are in contact with the silicon steel sheet, the rubber sleeve can play a buffering role and prevent the surface of the silicon steel sheet from being worn. The rollers 3 located on the same connecting frame 2 are arranged at equal intervals. Setting a plurality of rollers 3 on the connecting frame 2 can increase the pressing area of the device on the silicon steel sheet, thereby improving the pressing effect. A cylinder 4 is fixed on the mounting bracket 1, and a control box 6 is provided inside the mounting bracket 1. The end of the output shaft of the cylinder 4 is fixed to the control box 6. A buffer assembly is provided inside the control box 6. The buffer assembly includes a slide plate 7 slidably connected inside the control box 6. A second airbag 9 is fixed between the upper surface of the slide plate 7 and the inner top surface of the control box 6. A first airbag 8 is jointly fixed between the lower surface of the slide plate 7 and the inner bottom surface of the control box 6. A connecting pipe 11 is communicated with the first airbag 8, and the connecting pipe 11 is communicated with the inside of the second airbag 9. A number of connecting rods 5 are fixed to the lower surface of the slide plate 7. One end of the connecting rod 5 away from the slide plate 7 extends to the outside of the control box 6, and the connecting rod 5 is fixed to the connecting frame 2. Under the action of the first airbag 8 and the second airbag 9, when the cylinder 4 controls the control box 6 to gradually move, the rollers 3 will first contact the silicon steel sheet and gradually apply pressure. Such a design plays a buffering role and prevents the rollers 3 from directly pressing the silicon steel sheet to cause deformation of the silicon steel sheet and thus affect its processing quality.

[0026] Refer to Figure 4 and Figure 5 , A guiding component is provided on the mounting bracket 1 located above the longitudinal shearing machine for silicon steel sheets. The guiding component includes fixing brackets 12 fixedly connected to both sides of the mounting bracket 1. The two fixing brackets 12 are symmetrical along the width direction of the silicon steel sheet. A fixing rod 13 is slidably connected inside the fixing bracket 1. One end of the fixing rod 13 extends to the outside of the fixing bracket 1, and a guiding wheel 14 is rotatably connected to the fixing rod 13. An airbag three 16 is jointly fixed between the fixing rod 13 and the fixing bracket 1. A spring 15 is further provided between the fixing rod 13 and the inner side of the fixing bracket 1. Under the elastic force of the spring 15 and the airbag three 16, the guiding wheel 14 will abut against the two edges of the silicon steel sheet, thereby realizing the guiding function.

[0027] Refer to Figure 3 and Figure 5, a fluid 10 is provided inside each of the first airbag 8, the second airbag 9 and the third airbag 16. The fluid 10 is an electrorheological fluid. Specifically, the electrorheological fluid is a suspension liquid that is in a liquid state under normal conditions and will instantaneously change from a liquid state to a solid state when subjected to an electric field. Its working principle and specific composition are not the innovative parts of the present utility model and will not be elaborated here. Under the action of the electrorheological fluid, the position of the guide wheel 14 and the drum 3 can be fixed, thereby improving the stability of the overall structure of the device. In addition, the first airbag 8, the second airbag 9 and the third airbag 16 are all made of rubber, which can isolate the interference of the external electric field and ensure the normal operation of the device.

[0028] The specific working principle of the present utility model is as follows:

[0029] The silicon steel sheet passes through between the two mounting brackets 1. Before shearing the silicon steel sheet, two cylinders 4 are started simultaneously. The output shafts of the cylinders 4 extend to drive the two control boxes 6 to move relatively. The movement of the control boxes 6 drives the connecting rods 5 and the connecting frames 2 to move towards each other, so that the drums 3 on the two connecting frames 2 can move towards each other, and the drums 3 at the upper and lower positions can respectively contact the upper and lower surfaces of the silicon steel sheet. As the control boxes 6 continue to move, at this time, the slide plate 7 and the connecting rod 5 slide relative to the control boxes 6, and the air in the second airbag 9 is squeezed and enters the first airbag 8 through the connecting pipe 11. In this way, under the elastic force of the first airbag 8 and the second airbag 9, the connecting frames 2 and the drums 3 always abut against the silicon steel sheet, thereby realizing the pressing effect on the silicon steel sheet, ensuring the straightness of the silicon steel sheet. Since the length of the drum 3 is the same as the length of the shearing machine of the silicon steel sheet, the length of the drum 3 will be greater than or equal to the width of the silicon steel sheet. Therefore, the force exerted by the drum 3 on the silicon steel sheet can be evenly distributed on the surface of the silicon steel sheet to prevent the silicon steel sheet from deforming. And as the silicon steel sheet is transmitted, the drum 3 will rotate while being pressed, which can reduce the friction between the drum 3 and the silicon steel sheet and ensure the smoothness and flatness of the surface of the silicon steel sheet;

[0030] Furthermore, before pressing the silicon steel sheet, the silicon steel sheet is passed through between the two guide wheels 14. Under the elastic force of the spring 15 and the third airbag 16, the guide wheels 14 will always abut against the two edges of the silicon steel sheet in the length direction, and the guide wheels 14 will rotate during the transmission of the silicon steel sheet. This can ensure that the position of the silicon steel sheet will not be skewed during the unfolding and transmission process, so that the width of the sheared silicon steel sheet remains consistent and the processing quality of the silicon steel sheet is improved;

[0031] Furthermore, a fluid 10 is provided inside the first airbag 8, the second airbag 9, and the third airbag 16, and the fluid 10 is an electrorheological fluid. When the rollers 3 at the upper and lower positions clamp the silicon steel sheet at the upper and lower positions, and the guide wheels 14 abut against both sides of the silicon steel sheet, an electric current is applied to the electrorheological fluid. Under the action of the electric field, the state of the electrorheological fluid changes from a liquid state to a solid state, so that the positions of the rollers 3 and the guide wheels 14 can be fixed, the effect of pressing and guiding the silicon steel sheet by the device is improved, the stability of the overall structure of the device is ensured, and for silicon steel sheets with different thicknesses and widths, the device can press and guide them, which improves the practicability and flexibility of the device.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes an equivalent substitution or change, and should be covered by the protection scope of the present invention.
