[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a stamping and feeding device for stamping parts of electric vehicle frames, including a base plate 1; a positioning groove 11 is provided in the middle of the base plate 1; a placement platform 12 is fixedly connected to the end of the base plate 1; a stamping platform 13 is fixedly connected to the end of the placement platform 12; a stamping assembly 14 is fixedly connected to the end of the base plate 1; a connecting shell 15 is provided in the positioning groove 11; the base plate 1 and the connecting shell 15 are fixedly connected; a fixing cover 16 is fixedly connected to the end of the connecting shell 15; a first motor 17 is fixedly connected to the inner wall of the connecting shell 15; a gear rod 18 is rotatably connected to the output end of the first motor 17; a stabilizing plate 19 is fixedly connected to the inner wall of the connecting shell 15; a gear rod 18 is rotatably connected through the middle of the stabilizing plate 19; a drive cover 101 is rotatably connected to the end of the fixing cover 16; the drive cover 101... A drive gear 102 is fixedly connected to the end of the drive cover 101; the first motor 17 is meshed with the drive gear 102; a lifting sleeve 103 is fixedly connected to the end of the drive cover 101; a lifting ring 104 is slidably connected to the inner wall of the lifting sleeve 103; a lifting rod 105 is fixedly connected to the end of the lifting ring 104; the lifting sleeve 103 and the lifting rod 105 are slidably connected; a fixing recess 106 is fixedly connected to the end of the inner wall of the connecting shell 15; a second motor 107 is fixedly connected to the end of the fixing recess 106; a threaded rod 108 is rotatably connected to the output end of the second motor 107; the threaded rod 108 and the lifting ring 104 are rotatably slidably connected; multiple sets of limiting posts 109 are fixedly connected inside the lifting sleeve 103; the lifting ring 104 is fixedly connected to the surface of the limiting posts 109.During operation, the first motor 17 drives the gear rod 18 to rotate. The stabilizing plate 19 provides stability during gear rod 18 rotation, reducing vibration. Since the gear rod 18 is meshed with the drive gear 102, the gear rod 18 drives the drive gear 102 to rotate. The rotation of the drive gear 102 then drives the drive cover 101 and the lifting rod 105 fixed to it to rotate, causing the loading telescopic suction cup device connected to the lifting rod 105 to rotate. Simultaneously, the second motor 107 drives the threaded rod 108 to rotate, allowing the lifting ring 104 to slide inside the lifting sleeve 103, thus lifting the lifting rod 105. This allows the loading telescopic suction cup device connected to the lifting rod 105 to achieve the same lifting effect. At the same time, the limiting post 109 limits the lifting ring 104... This design serves as a limit switch and enhances the stability of the lifting ring 104 during lifting. The rotating lifting device allows for the rotation and lifting of the feeding telescopic suction cup connected to the lifting rod 105. Rotation facilitates the suction of sheet metal from outside the stamping device, while lifting allows for the retrieval of sheet metal at different heights, improving applicability. It also enhances the linkage effect when placing sheet metal on the stamping table, improving the overall linkage effect of the equipment. This design, through the rotation and lifting of the feeding telescopic suction cup, improves the applicability of the device. Furthermore, the mechanical linkage of the device allows for uniform setting of sheet metal retrieval and placement, improving the consistency of placement each time. This ensures consistent loading positions, reducing uneven stamping during stamping and minimizing labor costs and damage costs caused by differences in manual loading.

[0026] Furthermore, such as Figure 2 , Figure 3As shown, a telescopic plate 2 is fixedly connected to the end of the lifting rod 105; a positioning plate 21 is fixedly connected to the end of the telescopic plate 2; a third motor 22 is fixedly connected to the end of the positioning plate 21; a first rotating rod 23 is rotatably connected to the output end of the third motor 22; a first wheel 24 is fixedly connected to the middle of the first rotating rod 23; a first fixed rod 25 is rotatably connected to the end of the telescopic plate 2; a second wheel 26 is fixedly connected to the middle of the first fixed rod 25; the first wheel 24 and the second wheel 26 are both meshed with the first synchronous belt 27; A third set of wheels 28 is fixedly connected to the middle of the first fixed rod 25; a second fixed rod 29 is fixedly connected inside the telescopic plate 2; a fourth set of wheels 210 is rotatably connected to the surface of the second fixed rod 29; the third set of wheels 28 and the fourth set of wheels 210 are uniformly meshed with the second synchronous belt 211; a drive plug 212 is fixedly connected to the surface of the second synchronous belt 211; a connecting plate 213 is provided on the top of the drive plug 212; the drive plug 212 and the connecting plate 213 are fixedly connected; during operation, the third motor 22 is started to drive... The first rotating rod 23 rotates, driving the first set of wheels 24 to rotate. When the first set of wheels 24 rotates, the first synchronous belt 27 drives the second set of wheels 26 and the first fixed rod 25 to rotate. When the first fixed rod 25 rotates, the third set of wheels 28 rotates. When the third set of wheels 28 rotates, the second synchronous belt 211 drives the fourth set of wheels 210 to rotate. This allows the second synchronous belt 211 to drive the drive block 212 to slide, thereby driving the connecting plate 213 to slide. The movement of the second synchronous belt 211 drives the connecting plate 213 to slide, thereby driving the suction cup device to perform telescopic movement. This allows control over the movement range of the suction cup. By setting different extension lengths of the suction cup, it can be positioned at the center of boards of different shapes and sizes, improving the stability of the suction of the boards and increasing the flexibility of its movement when placing boards. This design, by adjusting the extension length of the suction cup device, allows it to be positioned at the center of different boards, improving the stability of the suction of the boards and increasing the flexibility of the device when placing boards.

[0027] Furthermore, such as Figure 3As shown, a fixed column 3 is fixedly connected inside the linkage plate 213; a fifth set of wheels 31 is rotatably connected to the surface of the fixed column 3; a suction cup 32 is fixedly connected to the end of the fifth set of wheels 31; a fourth motor 33 is fixedly connected to the end of the linkage plate 213; a second rotating rod 34 is rotatably connected to the output end of the fourth motor 33; a sixth set of wheels 35 is fixedly connected to the surface of the second rotating rod 34; the sixth set of wheels 35 and the fifth set of wheels 31 are meshed with the third synchronous belt 36; during operation, the fourth motor 33 is started to drive the second rotating rod 34 to rotate, which in turn drives the sixth set of wheels 35 to rotate, and when the sixth set of wheels 35 rotates, it drives the second set of wheels 26 to move forward. The movement of the suction cup 32 causes the fifth set of wheels 31 to rotate, which in turn causes the suction cup 32 to rotate. The rotation of the suction cup 32 can adjust the position of the plate being held, making it more suitable for stamping and resulting in a more even stamping force. At the same time, the distance between the fourth motor 33 and the fixed column 3 reduces the weight that would occur if the suction cup 32 were driven directly by the motor. This design uses a synchronous belt drive to distribute the gravity, improving the uniformity of the force on the equipment. In addition, the rotation of the suction cup adjusts the placement of the plate, improving the uniformity of the stamping.

[0028] Furthermore, such as Figure 4 As shown, a storage platform 4 is fixedly connected to the end of the base plate 1; a limiting frame 41 is fixedly connected to the side wall of the storage platform 4; a force-bearing frame 42 is fixedly connected to the end side wall of the limiting frame 41; a pressure alarm 43 is provided inside the force-bearing frame 42; the force-bearing frame 42 and the pressure alarm 43 are fixedly connected; during operation, when the board is removed, the pressure alarm 43 is set to a certain pressure level. When the weight of the board placed on the force-bearing frame 42 is lower than the set pressure level, the pressure alarm 43 will issue an alarm signal to remind the staff to fill the board in time, thus improving convenience. This design, through the set pressure device, can remind the staff of the number of boards. When there are few boards, a signal will be issued in time to remind the staff to fill the board, thus improving the convenience of using the equipment.

[0029] Furthermore, such as Figure 4 As shown, the limiting plate frame 41 has a placement groove 5 at its end; a magnetic block 51 is provided in the placement groove 5; the limiting plate frame 41 and the magnetic block 51 are fixedly connected; during operation, when the plate is moved out of the limiting plate frame 41 through the suction cup, the magnetic effect of the magnetic block 51 causes the like magnetic poles of the plate to repel each other, separating adjacent plates and bringing out the plates fixed by the suction cup, reducing the occurrence of double plates, thereby improving the accuracy of the equipment. This design utilizes the principle of like magnetic poles repelling each other to separate adjacent plates on the suction cup, reducing the occurrence of double plates and improving the accuracy of the equipment.

[0030] Furthermore, such as Figure 2 As shown, a guide rod 6 is fixedly connected to the end of the linkage plate 213; a guide block 61 is fixedly connected to the end of the stamping table 13. During operation, when a sheet is placed on the stamping table 13, the correctness of the sheet's placement can be determined by the positioning between the guide rod 6 and the guide block 61. If the guide rod 6 and the guide block 61 cannot be inserted in a corresponding manner, the operator can promptly detect and make adjustments. This design, by creating a positioning device for the placement position, enables timely detection and adjustment of sheet materials with misaligned positions, thereby improving the applicability of the equipment.

[0031] Furthermore, such as Figure 3 As shown, the positioning groove 11 has a stabilizing block 7 fixedly attached to its side wall in a circumferential array; the stabilizing block 7 is fixedly connected to the connecting shell 15; during operation, the stabilizing block 7 plays a role in fixing the connecting shell 15, reducing the shaking phenomenon of the connecting shell 15 caused by internal movement. This design improves the stability of the equipment during operation by enhancing the fixation of the connecting shell 15.

[0032] Working principle: During operation, the first motor 17 drives the gear rod 18 to rotate. As the gear rod 18 rotates, the stabilizing plate 19 provides stability, reducing vibration. Since the gear rod 18 is meshed with the drive gear 102, the gear rod 18 drives the drive gear 102 to rotate. The rotation of the drive gear 102 then drives the drive cover 101 and the lifting rod 105 fixed to it to rotate, causing the feeding telescopic suction cup device connected to the lifting rod 105 to rotate. Simultaneously, the second motor 107 drives the threaded rod 108 to rotate, allowing the lifting ring 104 to slide inside the lifting sleeve 103, thus stabilizing the lifting rod 105. The lifting rod 105 provides a lifting effect, allowing the feeding telescopic suction cup device connected to the lifting rod 105 to achieve the same lifting effect. Simultaneously, the limiting post 109 limits the lifting ring 104 and improves its stability during lifting. The rotating lifting device allows for the rotation and lifting of the feeding telescopic suction cup device connected to the lifting rod 105. Rotation facilitates the suction of sheet metal from outside the stamping device, while lifting allows for the handling of sheet metal of different heights, improving applicability. It also enhances the linkage effect when placing sheet metal on the stamping table, improving the overall linkage effect of the equipment. This design, through the rotation and lifting effect of the feeding telescopic suction cup device, improves the overall linkage effect of the equipment. The device's adaptability and mechanical linkage enable unified settings for the handling and placement of sheet metal, improving consistency in placement and ensuring consistent loading positions. This reduces uneven stamping during pressing and lowers labor costs and damage costs caused by manual loading discrepancies. During operation, the third motor 22 drives the first rotating rod 23 to rotate, which in turn drives the first set of wheels 24. The rotation of the first set of wheels 24, via the first synchronous belt 27, drives the second set of wheels 26 and the first fixed rod 25. The rotation of the first fixed rod 25, in turn, drives the third set of wheels 28. The rotation of the third set of wheels 28, via the second synchronous belt 211, drives the fourth set of wheels 21. The rotation of the second synchronous belt 211 causes the drive block 212 to slide, which in turn causes the connecting plate 213 to slide. The movement of the second synchronous belt 211 drives the connecting plate 213 to slide, which in turn causes the suction cup device to extend and retract. This allows control over the suction cup's range of motion. By adjusting the extension length of the suction cup, it can be positioned at the center of different shaped and sized boards, improving the stability of the board suction and enhancing its flexibility during board placement. This design, by adjusting the extension length of the suction cup device, allows it to be positioned at the center of different boards, improving the stability of the board suction and enhancing the flexibility of the device during board placement.During operation, the fourth motor 33 drives the second rotating rod 34 to rotate, which in turn drives the sixth set of wheels 35 to rotate. The rotation of the sixth set of wheels 35 drives the second set of wheels 26, which in turn drives the fifth set of wheels 31 to rotate. This, in turn, drives the suction cup 32 to rotate. The rotation of the suction cup 32 allows for the adjustment of the held sheet metal, ensuring a more suitable position for stamping and resulting in a more even stamping force. Simultaneously, the distance between the fourth motor 33 and the fixed column 3 reduces the impact of direct motor drive on the top of the suction cup 32. For heavier loads, this design uses a synchronous belt drive to distribute gravity, improving the uniformity of force application. Simultaneously, it adjusts the placement of the sheet metal by rotating the suction cup, enhancing the uniformity of stamping. During operation, the pressure alarm 43 is set to adjust the pressure level during sheet removal. When the weight of the sheet metal on the support frame 42 falls below the set pressure level, the alarm 43 sounds, reminding workers to replenish the sheet metal promptly, improving convenience. This design also uses a pressure device to monitor the number of sheet metal items; when the quantity is low, timely replenishment is necessary. The system sends a signal to remind workers to fill the sheet metal, improving the ease of use of the equipment. During operation, when the sheet metal is removed from the outlet of the limiting plate frame 41 by the suction cup, the magnetic effect of the magnetic block 51 causes the like magnetic poles of the sheet metal to repel each other, separating adjacent sheet metal pieces and bringing out the sheet metal fixed by the suction cup, reducing the occurrence of double materials and thus improving the accuracy of the equipment. This design utilizes the principle of like magnetic poles repelling each other to separate adjacent sheet metal pieces on the suction cup, reducing the occurrence of double materials and improving the accuracy of the equipment. During operation, when the sheet metal is placed on the stamping table 13, it can be... The positioning between guide rod 6 and guide block 61 is used to determine whether the plate is correctly placed. If guide rod 6 and guide block 61 cannot be inserted correctly, the operator can promptly identify and correct the issue. This design, by incorporating a positioning device, allows for timely detection and adjustment of misaligned plates, improving the equipment's applicability. During operation, stabilizing block 7 secures the connecting shell 15, reducing vibration caused by internal movement. This design enhances the stability of the equipment during operation by improving the fixation of the connecting shell 15.
