[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1, please refer to Figures 1 to 9 , a cutting and bending device for processing the iron core of an instrument transformer, including a processing table 1. A runner 103 is rotatably arranged at the central position of the processing table 1. Refer to Figure 2 It can be seen that since an embedded motor is installed inside the processing table 1 and a fixed connection is formed between the output end of the embedded motor and the runner 103, when the iron core strip 107 is wound around the bending assembly 2 later, the user can start the embedded motor, and then let the embedded motor drive the runner 103 to rotate in order to complete the bending and winding process of the iron core strip 107.

[0029] Refer toFigure 2 It can be seen that a first accommodation cavity 104 is provided inside the runner 103, and a bending assembly 2 for bending the iron core strip 107 is slidably arranged inside the first accommodation cavity 104. Therefore, when the runner 103 rotates, the bending assembly 2 slidably arranged inside the first accommodation cavity 104 will also rotate synchronously. By positioning the iron core strip 107 on the bending assembly 2 and using the subsequent rotation of the bending assembly 2, the bending and winding process of the iron core strip 107 can be achieved. As for the positioning operation of the iron core strip 107, it belongs to the prior art, and those skilled in the art can select it according to actual needs. A cutting assembly 102 for cutting the transformer iron core after bending is also provided on the processing table 1. When the bending of the iron core strip 107 is completed, the cutting of the iron core strip 107 can be achieved by controlling the cutting assembly 102, which is convenient for the subsequent processed workpiece to be separated from the bending assembly 2. A welding assembly 101 for welding the transformer iron core after bending is provided on the processing table 1. The welding assembly 101 is used to weld the cut iron core strip 107 to fix the bent and wound iron core strip 107 into a whole. The welding assembly 101 is the prior art, and those skilled in the art can select it according to actual needs.

[0030] The bending assembly 2 is composed of a positioning plate 201, a bending cross plate 202, a bending vertical plate 203 and a limiting plate 204. There are two groups of bending cross plates 202 and bending vertical plates 203, and the two groups of bending cross plates 202 and bending vertical plates 203 are symmetrically arranged on the positioning plate 201. The positioning plate 201 is composed of a positioning front plate 2011 and a positioning rear plate 2012. Each group of bending cross plates 202 and each group of bending vertical plates 203 are slidably arranged between the positioning front plate 2011 and the positioning rear plate 2012. A fixed connection is formed between the limiting plate 204 and the positioning rear plate 2012. According to Figure 2 It can be seen that since an embedded cylinder is also installed inside the first accommodation cavity 104, and a fixed connection is formed between the output end of the embedded cylinder and the extrusion push rod 105, when the user needs to perform demolding of the bent iron core strip 107, the user can start the embedded cylinder to drive the extrusion push rod 105 to move inside the first accommodation cavity 104.

[0031] At the same time, refer to Figure 2 and Figure 3It can be seen that a connecting sleeve 206 is also fixedly connected to the inner wall of the positioning front plate 2011. An extrusion push rod 105 is slidably arranged inside the connecting sleeve 206, and a second spring 219 for connection is also arranged between the extrusion push rod 105 and the connecting sleeve 206. A plurality of first chutes 217 are formed in the inner walls of the positioning front plate 2011 and the positioning rear plate 2012. Each group of bent cross plates 202 is composed of a first cross plate 2021 and a second cross plate 2022, and each group of bent vertical plates 203 is composed of a first vertical plate 2031 and a second vertical plate 2032. The first cross plate 2021, the second cross plate 2022, the first vertical plate 2031 and the second vertical plate 2032 are respectively slidably arranged inside the corresponding first chutes 217. A plurality of positioning plug plates 205 are also arranged between the positioning front plate 2011 and the positioning rear plate 2012. A plurality of second chutes 218 are formed in the inner walls of the positioning front plate 2011 and the positioning rear plate 2012. The plurality of positioning plug plates 205 are respectively slidably arranged inside the corresponding second chutes 218; A first insertion rod 210 and a second insertion rod 211 are installed on each positioning plug plate 205. One end of a connecting slide rod 207 is connected to the bottom surface of each positioning plug plate 205. A plurality of limit grooves 106 for changing the position of the connecting slide rod 207 are formed in the extrusion push rod 105. The other ends of the plurality of connecting slide rods 207 are respectively slidably arranged inside the corresponding limit grooves 106. The limit grooves 106 are divided into a first moving position 1061 and a second moving position 1062. One end of two movable connecting rods 208 is movably connected to the connecting slide rod 207. Moving chutes 209 are formed in the inner walls of the first cross plate 2021 and the second cross plate 2022. The other ends of the two movable connecting rods 208 are slidably arranged inside the corresponding moving chutes 209; Since the rod body of the extrusion push rod 105 penetrates through the limit plate 204 and the positioning rear plate 2012, and the front end of the extrusion push rod 105 is slidably arranged inside the connecting sleeve 206 arranged on the inner wall of the positioning front plate 2011, and the positioning front plate 2011 is fixedly connected to the connecting sleeve 206, and the other end of the connecting sleeve 206 is fixedly connected to the positioning rear plate 2012. At the same time, referring to Figure 8 It can be seen that a second spring 219 for connection is also arranged between the extrusion push rod 105 and the connecting sleeve 206. When the extrusion push rod 105 is pulled back and moved by the embedded cylinder, the extrusion push rod 105 will synchronously stretch the second spring 219; A limiting groove 106 is formed in the extrusion push rod 105, and the limiting groove 106 is composed of a first moving position 1061 and a second moving position 1062. The opening depth of the first moving position 1061 is greater than that of the second moving position 1062. When the extrusion push rod 105 moves, the connecting slide rod 207 arranged inside the second moving position 1062 will gradually slide into the first moving position 1061, thereby driving the connecting slide rod 207 to approach the center position of the extrusion push rod 105. A spherical ball is arranged at the end of the connecting slide rod 207. By using the arrangement of the spherical ball, it is ensured that the connecting slide rod 207 will not be separated from the limiting groove 106. Both ends of the connecting slide rod 207 are hinged with movable connecting rods 208, and the ends of the movable connecting rods 208 are slidably arranged inside the moving chute 209. A spherical ball is also arranged at the end of the movable connecting rod 208 to ensure that the movable connecting rod 208 will not be separated from the moving chute 209. At the same time, by using the positioning plug 205 arranged at the end of the connecting slide rod 207, the positioning plug 205 is slidably arranged in the second chute 218 formed on the positioning front plate 2011 and the positioning rear plate 2012. Through the arrangement of the second chute 218, it is ensured that the connecting slide rod 207 can only slide up and down; See Figure 5 And Figure 6 , when the connecting slide rod 207 moves in the direction of the extrusion push rod 105, the connecting slide rod 207 will first drive the positioning plug 205 to move downward, so that the positioning plug 205 gradually separates from the second cross plate 2022 and the first cross plate 2021, creating a contraction gap between the first cross plate 2021 and the second cross plate 2022, facilitating the subsequent contraction movement of the first cross plate 2021 and the second cross plate 2022. Through the arrangement of the moving chute 209, when the connecting slide rod 207 slides, it will drive the movable connecting rod 208 to slide inside the moving chute 209 first, avoiding the situation where the first cross plate 2021 and the second cross plate 2022 start to contract during the initial sliding of the connecting slide rod 207. When the positioning plug 205 is completely separated from the first cross plate 2021 and the second cross plate 2022, at this time, the movable connecting rod 208 slides to one end of the moving chute 209. As the connecting slide rod 207 continues to slide, at this time, the first cross plate 2021 and the second cross plate 2022 are driven to move downward by the movable connecting rod 208. Both the first cross plate 2021 and the second cross plate 2022 slide on the inclined groove first chute 217 through sliders. By using the inclined first chute 217, while the first cross plate 2021 and the second cross plate 2022 slide downward, the two gradually approach each other, and the movement modes of the first vertical plate 2031 and the second vertical plate 2032 are the same as those of the first cross plate 2021 and the second cross plate 2022, thereby realizing that the first cross plate 2021, the second cross plate 2022, the first vertical plate 2031, and the second vertical plate 2032 all approach and contract towards each other, and finally fit together as Figure 7As shown, by using the contraction movement of the first horizontal plate 2021, the second horizontal plate 2022, the first vertical plate 2031 and the second vertical plate 2032, the gap between the iron core strip 107 completed by bending and winding and the first horizontal plate 2021, the second horizontal plate 2022, the first vertical plate 2031 and the second vertical plate 2032 is increased, so as to facilitate the separation of the processed workpiece from the bending assembly 2.

[0032] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that the workpiece cannot be automatically separated only by increasing the gap between the bending horizontal plate 202 and the bending vertical plate 203 and the processed workpiece. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 9 , one end of the limiting plate 204 is fixedly connected with a third spring 108, and the third spring 108 is arranged inside the first accommodating cavity 104; When the bending horizontal plate 202 and the bending vertical plate 203 contract to the maximum position, at this time, when the extrusion push rod 105 continues to move, the connecting slide rod 207 moves to the end of the first moving position 1061. At this time, with the continuous movement of the extrusion push rod 105, it will drive the positioning front plate 2011 and the positioning rear plate 2012 arranged at the end of the connecting sleeve 206 to move together with the extrusion push rod 105. The positioning rear plate 2012 is fixedly connected with the limiting plate 204, so as to make the limiting plate 204 slide inside the first accommodating cavity 104 and compress the third spring 108, realizing the overall contraction movement of the bending assembly 2. By using the overall contraction movement of the bending assembly 2, the bent workpiece on the bending assembly 2 is made to contact the runner 103, so as to achieve the effect of automatically separating and falling off from the bending assembly 2. It should be noted that the rigidity of the third spring 108 is relatively large, and only when the bending horizontal plate 202 and the bending vertical plate 203 contract to the maximum position, can the third spring 108 generate deformation at this time.

[0033] Embodiment 3. The purpose of this embodiment is to facilitate the solution of the problem that it is difficult to ensure that the first horizontal plate 2021 and the second horizontal plate 2022 are always in the same horizontal plane when they contract and approach each other. This embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1 to 9 , second accommodating cavities 212 are respectively opened inside the second horizontal plate 2022 and the second vertical plate 2032. A sliding block 213 is arranged inside the second accommodating cavity 212. The sliding block 213 is slidably arranged on the inner wall of the second accommodating cavity 212, and a first spring 215 for resetting is further arranged between the sliding block 213 and the second accommodating cavity 212. A connecting insertion rod 214 is installed on the sliding block 213. Connecting slots 216 for the connecting insertion rod 214 to be inserted are respectively opened inside the first horizontal plate 2021 and the first vertical plate 2031. A fourth spring 109 is arranged inside the first sliding groove 217; A sliding block 213 is slidably arranged inside the second accommodating cavity 212, and a resisting inclined surface is arranged on one side of the sliding block 213 close to the second inserting rod 211. When the positioning insertion plate 205 follows the connecting sliding rod 207 and slides towards the extrusion push rod 105, at this time, the first inserting rod 210 and the second inserting rod 211 arranged on both sides of the positioning insertion plate 205 will move simultaneously with the connecting sliding rod 207, as shown in Figure 6 , as the second inserting rod 211 slides downward, at this time, the first spring 215 in a compressed state arranged on one side of the sliding block 213 will drive the sliding block 213 to slide leftward for reset. A connecting inserting rod 214 is fixedly arranged on the top of the sliding block 213, and further drives the connecting inserting rod 214 to slide synchronously inside the second cross plate 2022. When the connecting inserting rod 214 slides into the connecting slot 216, at this time, the positioning insertion plate 205 has not completely separated from the positioning front plate 2011 and the positioning rear plate 2012. When the first cross plate 2021 and the second cross plate 2022 are completely separated from the positioning insertion plate 205, at this time, the connecting inserting rod 214 inserts one-third into the connecting slot 216, making the first cross plate 2021 and the second cross plate 2022 form a relatively stable whole, ensuring the stability when the first cross plate 2021 and the second cross plate 2022 contract. When the first cross plate 2021 and the second cross plate 2022 are completely contracted and attached, at this time, the connecting inserting rod 214 completely inserts into the connecting slot 216. By using the settings of the first inserting rod 210 and the second inserting rod 211, when the first inserting rod 210 and the second inserting rod 211 are respectively inserted into the first cross plate 2021 and the second cross plate 2022, the first cross plate 2021 and the second cross plate 2022 are ensured to be stable by the first inserting rod 210 and the second inserting rod 211; It should be noted that a fourth spring 109 is arranged inside the first sliding groove 217, and the rigidity of the fourth spring 109 is relatively large. When the positioning insertion plate 205 is completely separated from the first cross plate 2021 and the second cross plate 2022, at this time, the sliding blocks fixed on the outer walls of the first cross plate 2021 and the second cross plate 2022 will slide inside the first sliding groove 217 and squeeze the fourth spring 109. The sliding modes of the first vertical plate 2031 and the second vertical plate 2032 are the same as those of the first cross plate 2021 and the second cross plate 2022.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to this process, method, article or device.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
