Description

Technical Field

[0001] The invention relates to the technical field of transformer core processing, in particular to a cutting and bending device for transformer core processing. Background Art

[0002] The transformer core is a crucial component of the transformer, primarily used to increase the magnetic flux in the transformer's air magnetic circuit. It typically consists of a main core, a secondary core (primarily used to improve accuracy and stability, typically only used in current transformers), clamps, and fixings.

[0003] When manufacturing a transformer core, the corresponding bending parts are generally rotated to bend and wind the core bars to obtain the corresponding transformer core. After the bending parts in the prior art complete the bending and winding of the core bars, they usually use a telescopic method to complete the blanking effect of the transformer core. Since the general shape of the bending parts is a rectangular iron block, if the core bars are bent and wound too tightly by such bending parts, it is very likely that the wound transformer core will be difficult to separate from the bending parts.

[0004] Therefore, the existing demand is not met, and we have proposed a cutting and bending equipment for transformer core processing. Summary of the Invention

[0005] The present invention provides a cutting and bending device for processing transformer cores. By resetting the bending horizontal plate and the bending vertical plate in advance to release the support for the completed transformer core, it can, to a certain extent, prevent the bending horizontal plate and the bending vertical plate from supporting the completed transformer core too tightly, so that the completed transformer core is difficult to detach from the bending assembly, thereby affecting the unloading of the completed transformer core, thereby solving the problems mentioned in the above background technology.

[0014] As an optional solution of the cutting and bending equipment for processing transformer cores described in the present invention, a second accommodating cavity is opened inside the second horizontal plate and the second vertical plate, and a sliding block is provided inside the second accommodating cavity.

When the positioning plug plate is completely separated from the bending horizontal plate and the bending vertical plate, the first horizontal plate, the second horizontal plate, the first vertical plate and the second vertical plate are driven to close and contract, allowing them to contract while still maintaining an integral whole, thereby increasing the gap between the processed workpiece on the bending assembly, thereby facilitating the separation of the workpiece and the bending assembly.

[0020] 2. The cutting and bending equipment for processing the transformer core uses sliding blocks and connecting rods respectively arranged inside the bending horizontal plate and the bending vertical plate. When the positioning plate is separated from the bending horizontal plate and the bending vertical plate, the connecting rod will be inserted into the connecting slot to ensure the stability of the bending horizontal plate and the bending vertical plate during the contraction process. At the same time, the first rod, the second rod and the positioning plate are used to ensure stable support for the bending horizontal plate and the bending vertical plate after they are fully expanded, thereby avoiding deformation of the bending assembly during the bending of the core bar.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1 to 9 A cutting and bending device for processing transformer cores, comprising a processing table 1, a rotating wheel 103 is provided at the center of the processing table 1, Figure 2It 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 rotating wheel 103, when the subsequent core bar 107 is wound on the bending component 2, the user can start the embedded motor, and then let the embedded motor drive the rotating wheel 103 to rotate, so as to complete the bending and winding process of the core bar 107.

[0035] See Figure 2 It can be seen that a first accommodating cavity 104 is provided inside the rotating wheel 103, and a bending assembly 2 for bending the core bar 107 is slidably provided inside the first accommodating cavity 104. Therefore, when the rotating wheel 103 rotates, the bending assembly 2 slidably provided inside the first accommodating cavity 104 will also rotate synchronously. By positioning the core bar 107 on the bending assembly 2, the subsequent rotation of the bending assembly 2 is utilized to achieve the bending and winding processing of the core bar 107. As for the positioning operation of the core bar 107, it belongs to the existing technology, and those skilled in the art can select it according to actual needs. The processing table 1 is also provided with a The cutting assembly 102 for cutting the transformer core after bending is completed. When the core bar 107 is bent, the core bar 107 can be cut by controlling the cutting assembly 102, so that the workpiece completed in subsequent processing is separated from the bending assembly 2. A welding assembly 101 for welding the transformer core after bending is provided on the processing table 1. The welding assembly 101 is used to weld the cut core bar 107, so that the bent and wound core bar 107 is fixed into a whole. The welding assembly 101 is an existing technology, and those skilled in the art can select it according to actual needs.

[0036] The bending assembly 2 is composed of a positioning plate 201, a bending transverse plate 202, a bending vertical plate 203 and a limiting plate 204. The bending transverse plate 202 and the bending vertical plate 203 are each provided with two groups, and the two groups of bending transverse 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 transverse 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. The limiting plate 204 is fixedly connected to the positioning rear plate 2012. Figure 2 It can be seen that since an embedded cylinder is also installed inside the first accommodating 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 bend and demold the core bar 107, the user can start the embedded cylinder to drive the extrusion push rod 105 to move inside the first accommodating cavity 104.

[0037] Also, see Figure 2 and Figure 3It can be seen that the inner wall of the positioning front plate 2011 is fixedly connected to a connecting sleeve 206, an extrusion push rod 105 is slidably provided inside the connecting sleeve 206, and a second spring 219 for connection is provided between the extrusion push rod 105 and the connecting sleeve 206. The inner walls of the positioning front plate 2011 and the positioning rear plate 2012 are provided with a plurality of first sliding grooves 217. Each group of bent horizontal plates 202 is composed of a first horizontal plate 2021 and a second horizontal plate 2022, and each group of bent vertical plates 203 is composed of a first vertical plate 203. 1 and the second vertical plate 2032, the first horizontal plate 2021, the second horizontal plate 2022, the first vertical plate 2031 and the second vertical plate 2032 are respectively slidably arranged in the corresponding first sliding grooves 217, a plurality of positioning plugs 205 are further arranged between the positioning front plate 2011 and the positioning rear plate 2012, and a plurality of second sliding grooves 218 are further opened on the inner walls of the positioning front plate 2011 and the positioning rear plate 2012, and the plurality of positioning plugs 205 are respectively slidably arranged in the corresponding second sliding grooves 218;

[0038] A first plug rod 210 and a second plug rod 211 are installed on each positioning plug plate 205, and one end of a connecting slide rod 207 is connected to the bottom surface of each positioning plug plate 205. A plurality of limiting grooves 106 for changing the position of the connecting slide rod 207 are also provided on the extrusion push rod 105. The other ends of the connecting slide rods 207 are respectively slidably set inside the corresponding limiting grooves 106. The limiting 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 also movably connected to the connecting slide rod 207. A movable slide groove 209 is provided on the inner wall of the first horizontal plate 2021 and the second horizontal plate 2022. The other ends of the two movable connecting rods 208 are slidably set inside the corresponding movable slide groove 209;

[0039] Since the rod of the extrusion push rod 105 passes through the limiting 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 provided on the inner wall of the positioning front plate 2011, and the positioning front plate 2011 and the connecting sleeve 206 are fixedly connected, and the other end of the connecting sleeve 206 is fixedly connected to the positioning rear plate 2012, refer to Figure 8 It can be seen that a second spring 219 is provided between the extrusion push rod 105 and the connecting sleeve 206 for connection. When the extrusion push rod 105 is pulled back by the embedded cylinder, the extrusion push rod 105 will synchronously stretch the second spring 219.

[0040] A limiting groove 106 is provided on the extrusion push rod 105, and the limiting groove 106 consists of a first moving position 1061 and a second moving position 1062. The opening depth of the first moving position 1061 is greater than the opening depth of the second moving position 1062. When the extrusion push rod 105 moves, the connecting slide 207 set inside the second moving position 1062 will gradually slide into the inside of the first moving position 1061, thereby driving the connecting slide 207 to approach the center position of the extrusion push rod 105. A ball is provided at the end of the connecting slide 207. The setting of the ball is used to ensure that the connecting slide 207 will not come into contact with the limiting groove 1061. The positioning slots 106 are separated, and the two ends of the connecting slide 207 are hingedly provided with movable links 208, and the ends of the movable links 208 are slidably arranged inside the movable slide slots 209, and the ends of the movable links 208 are also provided with balls to ensure that the movable links 208 and the movable slide slots 209 will not separate. At the same time, the positioning plug plate 205 provided at the end of the connecting slide 207 is used, and the positioning plug plate 205 is slidably set in the second slide slots 218 opened on the positioning front plate 2011 and the positioning rear plate 2012. The setting of the second slide slots 218 ensures that the connecting slide 207 can only slide up and down;

[0041] See Figure 5 and Figure 6 When the connecting slide bar 207 moves toward the extrusion push rod 105, the connecting slide bar 207 will first drive the positioning plug plate 205 to move downward, allowing the positioning plug plate 205 to gradually separate from the second cross plate 2022 and the first cross plate 2021, so that there is a contraction gap between the first cross plate 2021 and the second cross plate 2022, which is convenient for the subsequent contraction movement of the first cross plate 2021 and the second cross plate 2022. By setting the movable slide groove 209, when the connecting slide bar 207 slides, it will drive the movable link 208 to slide inside the movable slide groove 209 first, avoiding the situation that the first cross plate 2021 and the second cross plate 2022 shrink in the early sliding stage of the connecting slide bar 207. When the positioning plug plate 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 movable sliding groove 209, and as the connecting slide rod 207 continues to slide, the first horizontal plate 2021 and the second horizontal plate 2022 are driven downward by the movable connecting rod 208, and the first horizontal plate 2021 and the second horizontal plate 2022 are both slid on the first sliding groove 217 of the inclined groove through the slider, and the first sliding groove 217 is used to make the first horizontal plate 2021 and the second horizontal plate 2022 slide downward, and the two gradually approach each other, and the movement mode of the first vertical plate 2031 and the second vertical plate 2032 is the same as the movement mode of the first horizontal plate 2021 and the second horizontal plate 2022, thereby achieving the first horizontal plate 2021, the second horizontal plate 2022, the first vertical plate 2031 and the second vertical plate 2032 all approach each other, shrink and close to each other, and finally fit together as shown in FIG. Figure 7As shown, 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 is utilized to increase the gap between the iron core bar 107 that has been bent and wound and the first horizontal plate 2021, the second horizontal plate 2022, the first vertical plate 2031 and the second vertical plate 2032, thereby facilitating the separation of the processed workpiece from the bending assembly 2.

[0042] Example 2: This example is intended to solve the problem that the workpiece cannot be automatically separated by only increasing the gap between the bent horizontal plate 202 and the bent vertical plate 203 and the finished workpiece. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1 to 9 , one end of the limiting plate 204 is fixedly connected to the third spring 108, and the third spring 108 is arranged inside the first accommodating cavity 104;

[0043] When the cam 202 and the cam 203 are in the closed position, the cam 203 is in the closed position, and the cam 203 is in the closed position, so that the cam 203 is in the closed position and the cam 203 is in the closed position.

[0044] Embodiment 3: This embodiment aims to solve the problem that it is difficult to ensure that the first horizontal plate 221 and the second horizontal plate 22 are always on the same horizontal plane when they are retracted and moved closer. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 9 The second transverse plate 2022 and the second vertical plate 2032 are each provided with a second accommodating cavity 212, a sliding block 213 is provided inside the second accommodating cavity 212, and 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 provided between the sliding block 213 and the second accommodating cavity 212, a connecting rod 214 is installed on the sliding block 213, and a connecting slot 216 for plugging the connecting rod 214 is provided inside the first transverse plate 2021 and the first vertical plate 2031, and a fourth spring 109 is provided inside the first sliding groove 217;

[0045] The sliding block 213 is slidably arranged inside the second accommodating cavity 212, and a resisting inclined surface is provided on the side of the sliding block 213 close to the second insertion rod 211. When the positioning plug plate 205 follows the connecting slide rod 207 to slide toward the extrusion push rod 105, the first insertion rod 210 and the second insertion rod 211 provided on both sides of the positioning plug plate 205 will simultaneously follow the connecting slide rod 207 to move. Figure 6 When the second plug rod 211 slides downward, the first spring 215 in the compressed state provided on one side of the sliding block 213 drives the sliding block 213 to slide back to the left. The top of the sliding block 213 is fixedly provided with a connecting plug rod 214, which in turn drives the connecting plug rod 214 to slide synchronously inside the second horizontal plate 2022. When the connecting plug rod 214 slides into the connecting slot 216, the positioning plug plate 205 has not yet been completely separated from the positioning front plate 2011 and the positioning rear plate 2012. When the first horizontal plate 2021 and the second horizontal plate 2022 are completely separated from the positioning plug plate 205, the connecting plug rod 214 is inserted into the connecting slot 216 three-quarters. One, the first cross plate 2021 and the second cross plate 2022 form a relatively stable whole, ensuring the stability of the first cross plate 2021 and the second cross plate 2022 when they are contracted. When the first cross plate 2021 and the second cross plate 2022 are completely contracted and fit together, the connecting rod 214 is completely inserted into the connecting slot 216. By utilizing the arrangement of the first rod 210 and the second rod 211, when the first rod 210 and the second rod 211 are respectively inserted into the first cross plate 2021 and the second cross plate 2022, the first rod 210 and the second rod 211 are utilized to ensure the stability of the first cross plate 2021 and the second cross plate 2022.

[0046] It should be noted that a fourth spring 109 is provided inside the first slide groove 217. The fourth spring 109 has a large rigidity. When the positioning plug plate 205 is completely separated from the first horizontal plate 2021 and the second horizontal plate 2022, the slider fixed on the outer wall of the first horizontal plate 2021 and the second horizontal plate 2022 will slide inside the first slide groove 217 and squeeze the fourth spring 109. The sliding mode of the first vertical plate 2031 and the second vertical plate 2032 is the same as the sliding mode of the first horizontal plate 2021 and the second horizontal plate 2022.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only 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 terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0048] The above is only a preferred embodiment of the present invention.
