Description

Technical Field

[0001] The utility model relates to the technical field of motor stator sector piece processing, and more specifically to a generator stator sector piece stamping and fixing device. Background Art

[0002] Generator stator segments are a crucial component of the generator stator, supporting and securing the stator coils while also dissipating heat and interacting with the rotor's magnetic field. Typically located on the periphery of the generator stator, they surround the stator core, forming a fan-like structure. The segments support the stator coils, securing them to the stator and maintaining their position and shape. Stamping generator stator segments is a common step in the manufacturing process. Stamping allows silicon steel sheets or other materials to be precisely machined into the desired segment shape, ensuring they meet design requirements and guaranteeing the generator's performance and efficiency. Stamping is a highly efficient processing method that can rapidly mass-produce large numbers of segments of the same shape, improving production efficiency and reducing costs.

[0003] For example, the utility model with announcement number CN214768267U discloses a stamping die for generator stator sector sheets, including a stamping table, the corners of the upper end face of the stamping table are connected to support rods, the top of the support rods is connected to a support plate, the upper end face of the support plate is installed with a cylinder, the output end of the cylinder is connected to a lifting plate, the bottom end face of the lifting plate is fixedly connected to an upper die, the middle part of the upper end face of the stamping table is fixedly connected to a lower die, and the bottom end face of the upper die is connected to several die punches. During stamping, the die punch is used to punch the material, and the ejecting block will move to the inside of the knife groove at the bottom end of the die punch. After the punching is completed, the ejecting block will move downward under the action of the first spring, thereby ejecting the waste material to prevent the waste material from being stuck on the die punch.

[0004] Regarding the above scheme: The inventor believes that the above reference document drives the lifting plate and the upper mold downward through the operation of the cylinder, so that the upper mold can cooperate with the lower mold to realize the stamping and production of the material, and when the upper mold moves downward, it can drive the wire rope for transmission, and the guide cone is driven to rotate through the third spring, rack, gear and rotating rod, thereby realizing the removal of debris. However, when the material is stamped and produced, the material is only placed on the upper side of the lower mold, and is not limited or fixed. This may cause a certain offset of the material when being stamped, resulting in errors in the stamping position. At the same time, the material that falls to the inside of the stamping table is not convenient for the staff to take out, and it is easy for debris to remain on the inside of the stamping table, which is inconvenient to clean the inside of the stamping table.

[0024] 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 embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figure 1-5 The upper mold 32 is fixedly connected to the upper mold 33, and the upper mold 33 is fixedly connected to the lower mold 33.

[0027] In addition, a hollow groove 37 is provided on the upper side of the lower mold 33, and the upper mold 32 can be connected to the first spring 35 through the installation groove 34, and the first spring 35 can install the top block 36. The setting of the first spring 35 and the top block 36 enables the upper mold 32 to exert a certain squeezing effect on the stamped waste when moving downward to stamp the material, thereby realizing the ejection of the waste, and the opening of the hollow groove 37 enables the ejected crushed material to fall smoothly to the inner side of the stamping table 1. A fixing mechanism is provided on the upper side of the stamping table 1, and a material guiding mechanism and a material discharging mechanism are provided on the inner side of the stamping table 1. The fixing mechanism can limit the material to be stamped, thereby reducing the possibility of the material being offset when being stamped, and the setting of the material guiding mechanism and the material discharging mechanism enables the stamped crushed and waste materials to slide smoothly from the inner side of the stamping table 1, thereby facilitating the subsequent processing of the crushed materials by the staff.

[0028] Specifically, the fixing mechanism includes a mounting plate 41 fixedly connected to the upper side of the punching table 1, two mounting plates 41 are provided, a bidirectional screw 42 is rotatably connected between the two mounting plates 41, a limiting rod 43 is fixedly connected between the two mounting plates 41, the outer sides of the bidirectional screw 42 are threadedly connected to the first clamping plate 441 and the second clamping plate 442, the first clamping plate 441 and the second clamping plate 442 are both slidably connected to the outer sides of the limiting rod 43, the punching table 1 can play a role in installing and fixing the two mounting plates 41, and the mounting plate 41 can connect the bidirectional screw 42 and the limiting rod 43, and the threads on both sides of the bidirectional screw 42 are opposite;

[0029] In addition, the bidirectional screw 42 and the limiting rod 43 can connect the first clamping plate 441 and the second clamping plate 442, and the limiting rod 43 can limit the first clamping plate 441 and the second clamping plate 442. This makes it possible for the bidirectional screw 42 to smoothly drive the first clamping plate 441 and the second clamping plate 442 to move in opposite directions when the bidirectional screw 42 rotates. When the first clamping plate 441 and the second clamping plate 442 move to a certain distance, they can smoothly limit and fix the material, thereby reducing the possibility of the material being offset during stamping.

[0030] In addition, a connecting block 45 is fixedly connected to one side of one of the mounting plates 41, and a first servo motor 46 is fixedly connected to the upper side of the connecting block 45. The output shaft of the first servo motor 46 passes through one of the mounting plates 41, and the output shaft of the first servo motor 46 is fixedly connected to the bidirectional screw 42 through a coupling. One of the mounting plates 41 can install and fix the first servo motor 46 through the connecting block 45. When the first servo motor 46 is in operation, it can smoothly drive the bidirectional screw 42 to rotate, so that the rotation of the bidirectional screw 42 can be smooth and convenient enough.

[0031] Specifically, the material guiding mechanism includes a pad block 61 and a second spring 68 fixedly connected to the inner side of the punching table 1. The upper side of the pad block 61 is fixedly connected to the second servo motor 62. The output shaft of the second servo motor 62 is fixedly connected to the cam 63 through a coupling. The upper side of the second spring 68 is fixedly connected to the guide plate 66. The lower side of the guide plate 66 is fixedly connected to the fixed ring block 67. The punching table 1 can install and connect the second servo motor 62 through the pad block 61. The cam 63 connected to the output shaft of the second servo motor 62 enables the second servo motor 62 to smoothly drive the cam 63 to rotate during operation, and the second spring 68 can smoothly connect the guide plate 66.

[0032] In addition, the second spring 68 can reset the guide plate 66 through its own elasticity. The setting of the fixed ring block 67 enables the cam 63 to smoothly push the guide plate 66 through the fixed ring block 67 when the cam 63 is rotated by the operation of the second servo motor 62. The fixed ring block 67 is set on the outside of the cam 63. The inner side of the punching table 1 is fixedly connected to the fixed plate 64. One side of the guide plate 66 is fixedly connected to the movable plate 65. The movable plate 65 is slidably connected to one side of the fixed plate 64. The guide plate 66 can be connected to the movable plate 65.

[0033] In addition, the fixed plate 64 can limit the guide plate 66 through the movable plate 65, so that when the cam 63 pushes the fixed ring block 67, it can smoothly drive the guide plate 66 to move upward and reset it through the elasticity of the second spring 68, thereby realizing the up and down reciprocating motion of the guide plate 66, and the crushed materials that fall to the upper side of the guide plate 66 through the hollow groove 37 can slide down from the upper side of the guide plate 66 through the up and down movement of the guide plate 66.

[0034] Specifically, the discharging mechanism includes a fixed block 71 fixedly connected to the inner side of the punching table 1, and a discharging plate 72 is fixedly connected to the upper side of the fixed block 71. The discharging plate 72 is arranged on the lower side of the guide plate 66. A discharging port 73 is opened on one side of the punching table 1, and the discharging plate 72 is arranged on the inner side of the discharging port 73. A collecting box 74 is provided on the outer side of the punching table 1, and the collecting box 74 is arranged on the lower side of the discharging plate 72. The punching table 1 can connect the discharging plate 72 through the fixed block 71, and the crushed materials sliding down from the upper side of the guide plate 66 will fall to the upper side of the discharging plate 72, and slide out from the inner side of the punching table 1 through the discharging port 73, thereby falling to the inner side of the collecting box 74, so that the collecting box 74 can smoothly collect the crushed materials, which is convenient for the staff to handle the crushed materials and waste materials later.

[0035] Specifically, a limiting groove 91 is provided on the upper side of the stamping table 1, and the lower sides of the first clamping plate 441 and the second clamping plate 442 are fixedly connected to the limiting block 92, and the limiting block 92 is slidably connected to the inner side of the limiting groove 91. The first clamping plate 441 and the second clamping plate 442 can install and fix the limiting block 92, and when the first clamping plate 441 and the second clamping plate 442 move, they will drive the limiting block 92 to slide smoothly on the inner side of the limiting groove 91, so that the stamping table 1 can further limit the movement of the first clamping plate 441 and the second clamping plate 442 through the connection relationship between the limiting groove 91 and the limiting block 92, thereby increasing the stability of the first clamping plate 441 and the second clamping plate 442 during movement.

[0036] Specifically, a first rubber block 51 is fixedly connected to one side of the first clamping plate 441, and a second rubber block 52 is fixedly connected to one side of the second clamping plate 442. The arrangement of the first rubber block 51 and the second rubber block 52 can not only fill the gap between the first clamping plate 441 and the second clamping plate 442 and the material, but also increase the friction between the first clamping plate 441 and the second clamping plate 442 and the material, thereby improving the stability of the first clamping plate 441 and the second clamping plate 442 when limiting the material.

[0037] Specifically, a telescopic rod 8 is fixedly connected to the inner side of the stamping table 1, and the upper end of the telescopic rod 8 is fixedly connected to the lower end of the guide plate 66. The telescopic rod 8 is arranged on the inner side of the second spring 68. The telescopic rod 8 can limit the movement of the guide plate 66 through its own expansion and contraction, so that the guide plate 66 is not prone to deviation or shaking when it moves up and down through the rotation of the cam 63 and the elastic reset of the second spring 68, thereby increasing the stability of the guide plate 66 during use.

[0038] The working principle and usage process of the present invention: When the device is in use, the staff can place the material to be processed on the upper side of the lower mold 33, and then start the first servo motor 46. The first servo motor 46 will smoothly drive the bidirectional screw 42 to rotate during operation. When the bidirectional screw 42 rotates, it can drive the first clamping plate 441 and the second clamping plate 442 to move in opposite directions. After the first clamping plate 441 and the second clamping plate 442 move a certain distance, they can smoothly clamp and limit the material, reducing the possibility of the material being offset during stamping. After that, the staff can start the cylinder 31, and drive the upper mold 32 to move downward through the cylinder 31, so that the upper mold 32 and the lower mold 33 can smoothly stamp and process the material.

[0039] When the waste falls to the upper side of the guide plate 66 through the hollow groove 37, the staff can start the second servo motor 62. The second servo motor 62 will drive the cam 63 to rotate. When the cam 63 rotates, it will push the guide plate 66 upward through the fixed ring block 67, and then the weight of the guide plate 66 and the elasticity of the second spring 68 will drive the guide plate 66 to reset. The up and down reciprocating motion of the guide plate 66 realizes the vibration of the waste, so that the waste can slide to the upper side of the discharge plate 72, and then fall to the inner side of the collection box 74 through the discharge plate 72, thereby realizing the collection of the waste.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
