Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a stamping tooling for the capacitor housing, including support feet 1, the upper surface of the support feet 1 is fixedly connected with a bottom support plate 2, the upper surface of the bottom support plate 2 is fixedly connected with a motor cabinet 3 and a load-bearing column 5, the upper surface of the motor cabinet 3 is fixedly connected with a control cabinet 4, the upper surface of the load-bearing column 5 is fixedly connected with an upper fixing block 6, one side surface of the load-bearing column 5 is fixedly connected with a middle connecting block 7 and a lower positioning device 8, one side surface of the upper fixing block 6 is fixedly connected with a cylinder 9, one side surface of the cylinder 9 is fixedly connected with an auxiliary cylinder 10 and a pushing column 11, the lower surface of the pushing column 11 is fixedly connected with a stamping head 12, one side surface of the load-bearing column 5 is provided with a die changing mechanism 13, one side surface of the die changing mechanism 13 is provided with a module fixing mechanism 14, and the upper surface of the bottom support plate 2 is fixedly connected with a cylinder control console 15;

[0022] The mold replacement mechanism 13 includes a rotating motor 1301, a fixed disk 1302, a driven disk 1303, a driving rotating block 1304, a rotating shaft 1305, engaging teeth 1306, an engaging spring 1307, a limiting block 1308, a limiting groove plate 1309, an engaging bolt groove plate 1310 and a replacement rotating block 1311. The inner surface of the motor cabinet 3 is fixedly connected with the rotating motor 1301. One side surface of the rotating motor 1301 is rotatably connected with the fixed disk 1302. One side surface of the fixed disk 1302 is attached to the driven disk 1303 and fixedly connected with the limiting block 1308 and the limiting groove plate 1309. One side surface of the driven disk 1303 is rotatably connected with the driving rotating block 1304. One side surface of the driving rotating block 1304 is fixedly connected with the rotating shaft 1305. One side surface of the rotating shaft 1305 is rotatably connected with the engaging teeth 1306. One side surface of the engaging teeth 1306 is fixedly connected with the engaging spring 1307. One side surface of the limiting groove plate 1309 is slidably connected with the engaging bolt groove plate 1310. One side surface of the driven disk 1303 is fixedly connected with the replacement rotating block 1311. Through the settings of the rotating motor 1301, the fixed disk 1302, the driven disk 1303, the driving rotating block 1304, the rotating shaft 1305, the engaging teeth 1306, the engaging spring 1307, the limiting block 1308, the limiting groove plate 1309, the engaging bolt groove plate 1310 and the replacement rotating block 1311, during use, the engaging bolt groove plate 1310 is pulled out. At this time, the relative limitation between the fixed disk 1302 and the driven disk 1303 is cancelled. Subsequently, the rotating motor 1301 is started, and the rotating motor drives the driving rotating block 1304 to rotate. Due to the mutual fixation of the engaging teeth 1306, the engaging spring 1307 and the driven disk 1303, the gear on the driven disk 1303 only allows the engaging teeth 1306 to move in one direction, and the angle of each rotation is fixed, always keeping the top surface of the replacement rotating block 1311 horizontal. After rotating to the appropriate mold 1406, the engaging bolt groove plate 1310 is inserted into the limiting groove plate 1309 to complete the fixation of the fixed disk 1302 and the driven disk 1303. In this way, during subsequent mold replacement, there is no need to fix the bolts of the mold 1406 individually. Only the engaging bolt groove plate 1310 needs to be pulled out and the rotating motor 1301 needs to be started to select the appropriate mold 1406, which reduces the waste of time and improves the production rate.

[0023] Furthermore, there are two sets of symmetrically arranged support feet 1, bottom support plates 2 and load-bearing columns 5. One set of the fixed disk 1302 and the driven disk 1303 is arranged on each of the opposite sides of the two sets of load-bearing columns 5. Through the settings of the support feet 1, the bottom support plates 2 and the load-bearing columns 5, during use, it can provide more stable and balanced support for the entire tooling, disperse the pressure and weight generated during the operation of the tooling, and avoid equipment tilting, deformation or even damage caused by uneven unilateral force, thereby extending the service life of the equipment.

[0024] Further, there are six groups of the rotating shaft 1305, engaging teeth 1306 and engaging springs 1307 symmetrically arranged with respect to the central axis of the fixed disk 1302. The engaging teeth 1306 are engaged and connected to the driven disk 1303 through the engaging springs 1307. Through the arrangement of the rotating shaft 1305, engaging teeth 1306 and engaging springs 1307, during use, with six groups of the rotating shaft 1305, engaging teeth 1306 and engaging springs 1307 symmetrically arranged with respect to the central axis of the fixed disk 1302, the forces on the fixed disk 1302 and the driven disk 1303 in the circumferential direction can be made more uniform. During the rotation process, the multiple sets of symmetric structures can effectively avoid problems such as shaking and offset caused by uneven forces, ensuring stable transmission between the two disks, and thus ensuring the smooth progress of the mold replacement process.

[0025] Further, there are two groups of limit blocks 1308 arranged on one side surface of the fixed disk 1302. The fixed disk 1302 and the driven disk 1303 are fixedly connected through the engaging bolt groove plate 1310. Through the arrangement of the fixed disk 1302, the driven disk 1303 and the engaging bolt groove plate 1310, during use, the fixed disk 1302 and the driven disk 1303 are fixedly connected through the engaging bolt groove plate 1310, and the operation is simple and fast. Compared with traditional methods such as bolt connection, there is no need to tighten or loosen multiple bolts one by one. Only by inserting or removing the engaging bolt groove plate 1310 can the fixation or release of the two disks be achieved, shortening the mold replacement time and improving the production efficiency.

[0026] Further, the module fixing mechanism 14 includes a fixing groove 1401, a module fixing post 1402, a connecting bolt hole 1403, a threaded bolt 1404, a clamping rotating piece 1405 and a mold 1406. A fixing groove 1401 is formed on one side surface of the mold replacing mechanism 13. The inner surface of the fixing groove 1401 is slidably connected with a module fixing post 1402. A connecting bolt hole 1403 is formed on one side surface of the module fixing post 1402. A threaded bolt 1404 is slidably connected with the side surface of the connecting bolt hole 1403. A clamping rotating piece 1405 is fixedly connected to the lower surface of the threaded bolt 1404. A mold 1406 is fixedly connected to the upper surface of the module fixing post 1402. Through the settings of the fixing groove 1401, the module fixing post 1402, the connecting bolt hole 1403, the threaded bolt 1404, the clamping rotating piece 1405 and the mold 1406, when replacing the mold, first slide the module fixing post 1402 with the mold 1406 along the fixing groove 1401 to a proper position. Then, insert the threaded bolt 1404 into the connecting bolt hole 1403 and rotate the threaded bolt 1404 to make the lower clamping rotating piece 1405 clamped, so as to firmly fix the module fixing post 1402 on the mold replacing mechanism 13 and complete the installation of the mold 1406. When disassembling, operate in the reverse direction, loosen the threaded bolt 1404 to make the clamping rotating piece 1405 loose, and slide the module fixing post 1402 out along the fixing groove 1401. The sliding of the module fixing post 1402 is realized by using the fixing groove 1401, and in cooperation with the clamping method of the threaded bolt 1404 and the clamping rotating piece 1405, compared with the traditional complex installation method, the operation is simple, the mold can be replaced quickly, and time is saved.

[0027] Further, two groups of connecting bolt holes 1403 are symmetrically arranged with respect to the central axis of the module fixing post 1402. The threaded bolt 1404 and the clamping rotating piece 1405 are rotatably connected to the inner surface of each group of module fixing posts 1402. Through the settings of the module fixing post 1402, the connecting bolt hole 1403, the threaded bolt 1404 and the clamping rotating piece 1405, during use, the two groups of symmetrically arranged connecting bolt holes 1403 can make the connection between the module fixing post 1402 and the mold replacing mechanism 13 more stable. Fixed by two connection points, the force received by the mold during the working process can be evenly dispersed, avoiding problems such as insecure fixation or deformation of the module fixing post 1402 caused by single-point force, ensuring that the mold maintains a stable position during the stamping process, and improving the stamping quality.

[0028] Furthermore, the module fixing post 1402 is engaged with the connection bolt hole 1403 through the settings of the threaded bolt 1404 and the engaging rotating piece 1405. The mold 1406 is fixedly connected in the fixing groove 1401 through the module fixing post 1402. Through the settings of the module fixing post 1402, the connection bolt hole 1403, the threaded bolt 1404 and the engaging rotating piece 1405, during use, the module fixing post 1402 cooperates with the fixing groove 1401, and is engaged with the connection bolt hole 1403 through the threaded bolt 1404 and the engaging rotating piece 1405, enabling accurate initial positioning when installing the mold 1406. The dimensional and positional accuracies of the fixing groove 1401 and the connection bolt hole 1403 can ensure that the module fixing post 1402 and the mold 1406 are installed in the correct positions, ensuring that the relative positional relationship between the mold and other related components meets the design requirements, which is beneficial to improving the product consistency and quality stability.

[0029] Working principle: For this stamping tooling for the capacitor housing, through the setting of the mold replacement mechanism 13, when in use, the engaging bolt slot plate 1310 is pulled out. At this time, the relative limit between the fixed wheel disc 1302 and the driven wheel disc 1303 is cancelled. Subsequently, the rotation motor 1301 is started, and the rotation motor drives the active rotating block 1304 to rotate. Due to the mutual fixation of the engaging teeth 1306, the engaging spring 1307 and the driven wheel disc 1303, the gear on the driven wheel disc 1303 only allows the engaging teeth 1306 to move in one direction, and the rotation angle each time is fixed, always keeping the top of the replacement rotating block 1311 horizontal. After rotating to the appropriate mold 1406, the engaging bolt slot plate 1310 is inserted into the limit slot plate 1309 to complete the fixation of the fixed wheel disc 1302 and the driven wheel disc 1303. In this way, in subsequent mold replacements, there is no need to individually bolt-fix the mold 1406. Just pull out the engaging bolt slot plate 1310 and start the rotation motor 1301 to select the appropriate mold 1406, which reduces time waste and improves productivity. Through the setting of the module fixing mechanism 14, when replacing the mold, first slide the module fixing post 1402 with the mold 1406 along the fixing groove 1401 to the appropriate position. Then, insert the threaded bolt 1404 into the connection bolt hole 1403 and rotate the threaded bolt 1404 to make the lower engaging rotating piece 1405 tighten, thereby firmly fixing the module fixing post 1402 on the mold replacement mechanism 13 to complete the installation of the mold 1406; during disassembly, operate in the reverse direction, loosen the threaded bolt 1404 to make the engaging rotating piece 1405 loose, and slide the module fixing post 1402 out along the fixing groove 1401. By using the fixing groove 1401 to achieve the sliding of the module fixing post 1402 and cooperating with the tightening method of the threaded bolt 1404 and the engaging rotating piece 1405, compared with the traditional complex installation method, the operation is simple and the mold replacement can be quickly completed, saving time.
