Description

Technical Field

[0001] This utility model relates to the technical field of insulating paper forming equipment, and in particular to an insulating paper forming tooling. Background Technology

[0002] In the motor manufacturing process, the stator is a core component. Insulating paper needs to be inserted into its slots to achieve electrical insulation between the windings and the iron core, ensuring the safety and stability of motor operation. Therefore, the insertion of stator insulating paper is one of the key processes in motor assembly.

[0003] In the early days, the insertion of stator insulation paper relied heavily on manual operation. Operators had to manually shape the insulation paper and then insert it into the stator slots one by one. This method was not only labor-intensive and inefficient, but also prone to errors in manual operation, which could lead to misalignment, wrinkling, or even damage of the insulation paper, directly affecting the insulation performance of the stator and the overall quality of the motor, making it difficult to meet the needs of large-scale motor production.

[0004] To address the drawbacks of manual operation, automated stator insulation paper forming and insertion equipment has gradually emerged in the industry. This equipment uses mechanical structures to replace manual labor in the forming and insertion of insulation paper. Although automated stator insulation paper forming and insertion equipment has improved production efficiency to some extent, there are still many technical issues that need to be optimized in the forming process. The forming fixtures of existing equipment are mostly customized structures. When it is necessary to adapt to stator insulation paper of different slot types and sizes, the adjustment or replacement process of the fixtures is complicated, involving the disassembly and recalibration of multiple parts. This is not only time-consuming and labor-intensive, but also prone to a decrease in fixture accuracy due to frequent disassembly and assembly. It is difficult to meet the flexible production needs of multiple models and small batches of motors. Furthermore, the guiding and bending structure design of the insulation paper in the forming channel is not reasonable enough, which can easily lead to problems such as insulation paper jamming, folding angle deviation, and edge wrinkles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An insulating paper forming fixture includes a forming component mounted on an insulating paper forming device. A fixing component is fixed on the forming device, and the forming component can be quickly and easily detached from the forming device. The forming component includes a forming plate, and the forming plate has a forming channel for the insulating paper to pass through and bend into shape.

Through the cooperation of the forming groove and the forming channel, the double edges of the insulating paper are bent in stages to ensure that the folded edge shape is regular.

[0011] Preferably, the molded part further includes a bending guide block, which is assembled on the molded plate at the end near where the insulating paper enters. The molded plate has a guide surface at the end where the insulating paper enters, and the bending guide block is located on the side of the molded plate near the guide surface. The guide surface and the bending guide block cooperate to guide the insulating paper to feed smoothly, avoid feeding jamming, and improve the continuity of molding.

[0012] Preferably, the bending guide block includes a mounting block, the mounting block is provided with a guide plate, the guide plate is provided with symmetrically arranged inclined surfaces for guiding the insulating paper into the groove, and the guide plate is provided with a moving groove corresponding to the forming groove on the forming block.

[0023] Example: Please see Figure 1-8 An insulating paper forming fixture includes a forming component 2 installed on an insulating paper forming equipment 1. A fixing component 3 is fixed on the forming equipment 1. The forming component 2 can be quickly and easily fixed on the forming equipment 1 by means of the fixing component 3. The forming component 2 includes a forming plate 21. The forming plate 21 has a forming channel 213 for the insulating paper to pass through and bend into shape.

[0024] The fastener 3 is used to securely and quickly detachably fix the molded part 2 to the molding equipment 1. It includes a fixing plate 31, a quick clamp 32, and a fixing support plate 22. The fixing support plate 22 is fixedly installed on the molding equipment 1, and there are two fixing support plates 22. The two fixing support plates 22 are respectively arranged at both ends of the molding plate 21 in the molded part 2, providing a stable support foundation for the molding plate 21.

[0025] The fixed plate 31 and the fixed support plate 22 are fixedly connected one-to-one. Each fixed plate 31 is equipped with a quick clamp 32. The clamping end of the quick clamp 32 is set towards the forming plate 21. When the forming plate 21 is placed on the two fixed support plates 22, the clamping end of the quick clamp 32 can be pressed against the end of the forming plate 21 by operating the quick clamp 32, thereby quickly squeezing and fixing the forming plate 21 to the fixed support plate 22. Conversely, the quick clamp 32 can be released to release the fixing of the forming plate 21, realizing the quick disassembly of the forming part 2 and greatly simplifying the tooling assembly and disassembly process.

[0026] The forming component 2 is the core component for forming the insulating paper 4. It includes a forming plate 21, a bending guide block 23, a first forming block 24, and a second forming block 25. These components work together to accurately form the insulating paper 4. The forming plate 21 is composed of a first plate 211 and a second plate 212. After being assembled, the first plate 211 and the second plate 212 form a forming channel 213 through which the formed insulating paper 4 passes. The extension direction of the forming channel 213 is consistent with the forming and conveying direction of the insulating paper 4. The first plate 211 is also provided with a moving hole 215, which is used to adapt to the paper insertion assembly on the forming equipment 1 to move the formed insulating paper. Both the first plate 211 and the second plate 212 are provided with mounting grooves, the position and size of which are adapted to the forming blocks. The structure of molding block 24 and molding block 25 is such that molding block 24 and molding block 25 are both embedded in the mounting groove and fixedly connected to molding plate 21 by fasteners or welding to ensure that molding block 24 and molding block 25 do not shift during the molding process. Molding block 24 and molding block 25 are arranged vertically and vertically to form a complete molding structure after they are joined. Molding block 24 has a molding groove 241, and molding channel 26 is formed between molding block 24 and molding block 25. Molding block 25 has a molding groove 251, and molding groove 251 is connected to molding channel 26. The groove shape of molding groove 241 and molding groove 251 is adapted to the shape of the required folding edge of insulating paper 4, so as to realize the step-by-step molding of different edges of insulating paper 4.

[0027] The bending guide block 23 is assembled on the molding plate 21 near the end where the insulating paper 4 enters. Correspondingly, the molding plate 21 has a guide surface 214 at the end where the insulating paper 4 enters, which is used to guide the insulating paper 4 smoothly into the molding plate 21 and avoid jamming when the insulating paper 4 enters. The bending guide block 23 is set near the guide surface 214 and includes a mounting block 231 and a guide plate 232. The guide plate 232 is fixedly set on the mounting block 231, and the mounting block 231 is fixedly connected to the molding plate 21 by fasteners.

[0028] The guide plate 232 has symmetrically arranged inclined surfaces 233. The inclination angle of the inclined surfaces 233 is adapted to the entry angle of the insulating paper 4, which is used to guide the edges 4a and 4b of the insulating paper 4 to accurately enter the corresponding forming structures. The guide plate 232 also has a moving groove 234. The position of the moving groove 234 corresponds to the forming groove 241 on the forming block 24, forming a guide channel for the edge 4a of the insulating paper 4 to enter the forming groove 241, ensuring that the edge 4a accurately enters the forming groove 241.

[0029] When using this fixture, the insulating paper 4 entering the lower end of the forming plate 21 has been pre-crimped by the creasing equipment and has undergone preliminary bending. Subsequently, it is precisely formed using this fixture. The pre-bent insulating paper 4 moves towards the forming plate 21, first contacting the guide surface 214 of the forming plate 21. Guided by the guide surface 214, it smoothly enters the forming plate 21 and gradually approaches the bending guide block 23. The insulating paper 4 continues to move to the bending guide block 23. Under the action of the symmetrically arranged inclined surfaces 233 of the guide plate 232, the first edge 4a and the second edge 4b ​​of the insulating paper 4 are guided to their corresponding positions. The first edge 4a enters the forming groove 241 of the forming block 24 through the moving groove 234 on the guide plate 232, while the second edge 4b ​​exits from the guide plate 232 corresponding to the moving groove 234. One side enters the forming channel 26 and then enters the forming groove 251 of the forming block 25. The edge 4a entering the forming groove 241 bends along the groove shape to form an inner fold, and the edge 4b ​​entering the forming groove 251 bends along the groove shape to form an outer fold. Finally, the fold 4a is located on the inner side and the fold 4b is located on the outer side, forming a compliant insulating paper 4. The shaped insulating paper 4 moves upward through the forming channel 213 and directly connects to the paper insertion device on the forming equipment 1. The paper insertion device drives the folded insulating paper 4 to move upward for the next paper insertion operation, realizing a seamless connection between the forming and insertion stages and avoiding deformation or positional displacement of the insulating paper 4 during the transfer process.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
