Description

Technical Field

[0001] This application relates to the field of lamination trimming dies, and in particular to a structure for a motor stator lamination trimming die. Background Technology

[0002] Motor stator lamination trimming dies are specialized tooling for the precision machining of motor stator laminations. They belong to the category of stamping dies and their core function is to trim and shape the stator lamination blanks that have been initially formed by stamping, so that their inner and outer circle dimensions, tooth groove accuracy, flatness and other indicators meet the assembly requirements of the motor stator core. They are widely used in the field of motor manufacturing.

[0003] Regarding the aforementioned technologies, the inventors believe that current motor stator lamination trimming dies, after stamping and pressing out the contour, involve a cutting mechanism to cut the raw material steel scrap. However, a problem exists in the actual cutting process: specifically, the raw material steel scrap is not simultaneously cut off after stamping, requiring an additional cutting mechanism. This undoubtedly increases the complexity of the stamping and cutting process, resulting in low cutting efficiency. Therefore, the inventors urgently need to design a motor stator lamination trimming die structure to improve the synchronization of scrap cutting. Summary of the Invention

[0004] To improve the synchronization of waste material cutting, this application provides a motor stator lamination trimming die structure.

[0005] The technical solution for the motor stator lamination trimming die structure provided in this application is as follows: A stator lamination trimming die structure includes a stamping platform, a cutting mechanism, and a traction mechanism. The traction mechanism is located between the stamping platform and the cutting mechanism. The cutting mechanism includes a first fixing plate, one side of which is fixedly connected to a second fixing plate by bolts. The installation lengths of the first and second fixing plates are adjustable. The front end of the second fixing plate has a through hole, and an adjusting rod is movably connected to the through hole by bolts. A cutting blade is fixedly connected below the adjusting rod for adjusting the longitudinal position of the cutting blade. During the stamping process, the cutting mechanism moves longitudinally synchronously with the stamping platform, realizing the simultaneous production of finished laminations and the cutting of waste materials.

[0006] By adopting the above technical solution, the traction mechanism, stamping platform and cutting mechanism are integrated into a continuous and efficient stator lamination production and waste disposal structure, which directly optimizes the processing flow of motor stator laminations, effectively avoids the problem of separate lamination forming and waste cutting in the traditional motor stator production process, and greatly improves the efficiency of the production process.

[0007] Optionally, the first fixing plate and the second fixing plate are bolted together through straight slot holes.

[0008] By adopting the above technical solution, the first fixing plate and the second fixing plate are fixedly connected by bolts through a straight groove. The use of the straight groove lays the foundation for adjusting the relative position of the first fixing plate and the second fixing plate, effectively improving the accuracy of the adjustment and making the cutting mechanism suitable for more application scenarios.

[0009] Optionally, the surface of the adjusting rod is machined with multiple equidistant threaded holes for positioning the adjusting rod as it moves up and down.

[0010] By adopting the above technical solution, multiple positioning points are provided for the longitudinal adjustment of the cutting blade, and a more stable positioning guarantee is provided, which effectively improves the consistency and accuracy of waste material cutting, is applicable to the cutting of different waste materials, and increases the application scenarios of the cutting blade.

[0011] Optionally, the stamping platform is movably connected to the stamping base via a guide rod. The fixing plate is fixedly connected with bolts after engaging with a groove on the top of the stamping platform.

[0012] By adopting the above technical solution, the stamping platform and the stamping base are movably connected by the guide rod, which provides guidance for the longitudinal movement of the stamping platform. The guide rod also provides precise guidance for the smooth longitudinal movement of the stamping platform, effectively improving the accuracy of the stamping process.

[0013] Optionally, the traction mechanism includes a base, a first roller rotatably connected to the inner wall of the base, a second roller movably connected to the inner side of the base, and bearing seats sleeved at both ends of the second roller, with the bearing seats slidably connected to the base.

[0014] By adopting the above technical solution, roller one and roller two are installed and connected on the inner wall of the base, and bearing seats are sleeved at both ends of roller two to adjust the longitudinal movement of roller two, providing a flexible traction device for the stamping machine, which can realize the precise and stable conveying of stamping raw materials.

[0015] Optionally, a support plate is fixedly connected to the top of the base, and an adjusting screw is threadedly connected to the support plate. The end of the adjusting screw is rotatably connected to the bearing seat through a thrust bearing. A motor is provided on one side of the traction mechanism, and one side of the first roller is connected to the output end of the motor through a belt and a pulley.

[0016] By adopting the above technical solution, the end of the adjusting screw is rotatably connected to the bearing seat through the thrust bearing, providing a quick and convenient way to adjust the distance between the second roller and the first roller. The operator only needs to rotate the adjusting screw to drive the bearing seat to move the second roller smoothly, so that the distance between the two rollers can be adjusted to suit raw materials of different thicknesses.

[0017] Optionally, both roller one and roller two are rubber rollers, and roller one and roller two have the same length.

[0018] By adopting the above technical solution, both roller one and roller two are set as rubber rollers, which increases the friction between the roller and the raw material, thereby ensuring that the raw material can be pulled smoothly and reliably during the traction process, greatly reducing the situation where the raw material and the roller slide relative to each other, thus affecting the efficiency of stamping.

[0019] Optionally, the cutting blade is a detachable structure, and the cutting blade is fixedly connected to the adjusting rod by bolts or pressure plates, so as to quickly replace the cutting blade according to different stator lamination specifications.

[0020] Optionally, a positioning scale mark is provided between the first fixing plate and the second fixing plate of the cutting mechanism to indicate the installation length adjustment position of the cutting mechanism, so as to improve the accuracy and repeatability of the cutting position adjustment.

[0021] Optionally, the bottom of the base of the traction mechanism is provided with a vibration damping pad or a buffer pad, which is used to mitigate the impact of the traction mechanism by adopting the above-mentioned technical solution.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This application, through a cutting mechanism, forms a continuous and efficient integrated structure for stator lamination production and waste disposal, ensuring that the stamping and waste cutting steps are carried out simultaneously. This effectively avoids the problem of separate steps for lamination forming and waste cutting in the traditional motor stator production process, significantly improving the efficiency of waste cutting and reducing the complexity of installation.

[0023] This application utilizes a traction mechanism to continuously transport the stamped waste material to the cutting mechanism below for cutting, effectively supporting the continuity of motor stator lamination production and improving lamination efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a stator lamination trimming die structure for an electric motor. (Refer to...) Figure 1-4 The stator lamination trimming die structure includes a stamping platform 2, a cutting mechanism 3, and a traction mechanism 5. The traction mechanism 5 is located between the stamping platform 2 and the cutting mechanism 3. The cutting mechanism 3 includes a first fixing plate 301, one side of which is fixedly connected to a second fixing plate 302 by bolts. The installation lengths of the first fixing plate 301 and the second fixing plate 302 are adjustable. A through hole is machined at the front end of the second fixing plate 302, and an adjusting rod 303 is movably connected to the through hole by bolts. A cutting blade 304 is fixedly connected below the adjusting rod 303 for adjusting the longitudinal position of the cutting blade 304. During the stamping process, the cutting mechanism 3 moves longitudinally synchronously with the stamping platform 2, realizing the simultaneous production of finished stamped parts and the cutting of waste materials. This forms a continuous and efficient integrated structure for stator stamping production and waste material processing between the traction mechanism 5, the stamping base 1, and the stamping platform 2. This directly optimizes the processing flow of motor stator stamping, effectively avoiding the problem of separate steps in the traditional motor stator production process of stamping and waste material cutting. This significantly improves the efficiency of the production process and also avoids stamping positioning deviations caused by separate operations, further ensuring the quality of the finished stamped parts.

[0031] Reference Figure 1 The surfaces of fixing plate 301 and fixing plate 302 are machined with straight grooves, and fixing plate 301 and fixing plate 302 are bolted together through the straight grooves. The use of straight grooves lays the foundation for adjusting the relative position of fixing plate 301 and fixing plate 302, effectively improving the accuracy of adjustment and making the cutting mechanism 3 suitable for more application scenarios. At the same time, the structural stability after bolt connection ensures the stability and safety of the processing process and extends the service life of the mold.

[0032] Reference Figure 1The surface of the adjusting rod 303 is machined with multiple equidistant threaded holes for positioning the up and down movement of the adjusting rod 303. This provides multiple positioning points for the longitudinal adjustment of the cutting blade 304 and provides a more stable positioning guarantee, effectively improving the consistency and accuracy of waste material cutting. It is suitable for cutting different waste materials and increases the application scenarios of the cutting blade 304. At the same time, the threaded connection has the characteristics of simple structure, which facilitates the later maintenance or replacement of the adjusting rod 303 and the cutting blade 304, reducing equipment maintenance costs.

[0033] Reference Figure 1 , Figure 3 The stamping platform 2 is movably connected to the stamping base 1 fixing plate 301 via guide rod 6. The plate is engaged with the groove on the top of the stamping platform 2 and then fixed with bolts. The guide rod 6 enables the movable connection between the stamping platform 2 and the stamping base 1, providing guidance for the longitudinal movement of the stamping platform 2. The guide rod 6 provides precise guidance for the smooth longitudinal movement of the stamping platform 2, effectively improving the accuracy of the stamping process. At the same time, the connection method of fixing plate 301 engaging with the groove on the top of the stamping platform 2 and being fixed with bolts not only takes into account the convenience of installation and the stability of the connection, but also facilitates disassembly and replacement in the future.

[0034] Reference Figure 2 The traction mechanism 5 includes a base 504, with a first roller 501 rotatably connected to the inner wall of the base 504 and a second roller 502 movably connected to the inner side of the base 504. Bearing seats are sleeved at both ends of the second roller 502, and the bearing seats are slidably connected to the base 504. The first roller 501 and the second roller 502 are installed and connected to the inner wall of the base 504, and the bearing seats at both ends of the second roller 502 can adjust the longitudinal movement of the second roller 502, providing a flexible traction device for the stamping machine. It can achieve precise and stable delivery of stamping raw materials, and at the same time, it can be more portable and labor-saving, reducing the labor intensity of operators during the stamping process and alleviating the burden on operators.

[0035] Reference Figure 1 , Figure 2 , Figure 4A support plate 503 is fixedly connected to the top of the base 504. An adjusting screw is threaded onto the support plate 503. The end of the adjusting screw is rotatably connected to the bearing seat through a thrust bearing. A motor 4 is installed on one side of the traction mechanism 5. One side of the roller 501 is connected to the output end of the motor 4 via a belt 7 and a pulley. The end of the adjusting screw is rotatably connected to the bearing seat through a thrust bearing, providing a quick and convenient way to adjust the distance between the roller 502 and the roller 501. The operator only needs to rotate the adjusting screw to drive the bearing seat to move the roller 502 smoothly, realizing the adjustment of the distance between the two rollers to suit raw materials of different thicknesses. At the same time, the roller 501 is connected to the output end of the motor 4 via the belt 7 and the pulley, providing a stable and continuous power source for the rotation of the roller 501, thereby achieving uniform transportation of raw materials.

[0036] Reference Figure 2 Both roller 1 (501) and roller 2 (502) are rubber rollers, and their lengths are equal. The fact that both roller 1 (501) and roller 2 (502) are made of rubber increases the friction between the rollers and the raw materials, thereby ensuring that the raw materials can be pulled smoothly and reliably during the traction process. This greatly reduces the possibility of relative slippage between the raw materials and the rollers, which would affect the efficiency of stamping. At the same time, the fact that roller 1 (501) and roller 2 (502) are the same length avoids the problem of raw materials running off-center during transportation due to different roller lengths, effectively improving the stability of transportation.

[0037] The implementation principle of the motor stator lamination trimming die structure in this application embodiment is as follows: First, the raw material is passed through the gap between roller 1 501 and roller 2 502 and pulled back and forth to ensure that it can pass through the gap flexibly and smoothly. During the pulling process, roller 1 501 and roller 2 502 rotate relative to each other. Then, the fixing plate 2 302 and the adjusting rod 303 are adjusted to a suitable position. After the raw material is placed and fixed, the stamping device is opened and the stamping platform 2 moves up and down through the guide rod 6 to complete the stamping process. Then, the stamped waste material is driven by the rotation of the motor 4 to drive the belt 7 to rotate, thereby causing roller 1 501 to rotate and pull the waste material to the bottom of the cutting mechanism 3. The cutting blade 304 cuts the waste material at the same time.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
