Description

Technical Field

[0001] The utility model relates to the technical field of stamping equipment, in particular to a stamping forming device for a micro motor housing. Background Art

[0002] According to Chinese patent CN219924234U, a shell stamping forming device is disclosed, including a stamping table, a stamping plate and a stamping head. The stamping plate is movably installed on the top of the stamping table, and the stamping head is arranged at the bottom of the stamping plate. Fixed columns are fixedly installed on both sides of the stamping table, and movable columns are arranged inside the two fixed columns. One end of the two movable columns is provided with a shelf plate, and the top of the two shelf plates is provided with a plurality of fixed strips, and one end of the adjacent plurality of fixed strips is provided with a contact plate. By arranging fixed columns, rotating rods, shelf plates, contact plates, hydraulic cylinders and arc frames, a circular workpiece is placed on the surface of the two contact plates, and the distance between the two movable columns can be adjusted according to the diameter of the circular workpiece, so that the circular workpiece can be kept moving on the same straight line, and one side of the circular workpiece stops moving after contacting the arc frame, so that the circular workpiece can be moved to the center position of the stamping table, thereby improving the stamping quality of the stamping forming device.

[0003] The utility model can adjust the distance between the two moving columns according to the diameter of the circular workpiece, and can keep the circular workpiece moving on the same straight line. After one side of the circular workpiece contacts the arc frame, the movement stops, so that the circular workpiece can be moved to the center position of the stamping table, thereby improving the stamping quality of the stamping forming device.

[0004] However, the above technical solution still has the problem that when the stamping operation of the micromotor shell is performed, the shell and the shell cover need to be stamped separately and then assembled after completion. Because the shell needs to be heated during stamping, the raw material needs to be softened before stamping and then cooled to be better shaped. This makes the production speed of the shell slower than the production speed of the shell cover, which leads to an extension of the production cycle for the production of the shell during unified production. In order to solve this problem, the production line for the completed shell cover will be added to the production of the shell by replacing the mold. The traditional mechanical mold replacement requires a lot of time for disassembly and calibration, which is time-consuming and labor-intensive, takes up a lot of production time, and reduces the production speed.

[0005] To this end, the utility model provides a micro-motor housing stamping and forming device. Utility Model Content

Because the housing needs to be heated during stamping, the raw material needs to be softened before stamping and then cooled to be better shaped, which makes the production speed of the housing slower than that of the housing cover, which results in an extension of the production cycle for the production of the housing during unified production. In order to solve this problem, the production line for completing the housing cover will speed up the production of the housing by replacing the mold, while the traditional mechanical mold replacement requires a lot of time for disassembly and calibration, which is time-consuming and labor-intensive, takes up a lot of production time, and reduces the production speed.

The bottom of the clamping rod 21 is rotatably connected with a clamping column 24. The fixing column 23 extends to the inside of the clamping column 24 and rotates.

[0031] The blocking unit 3 is installed on the surface of the clamping rod 21 and is used to limit the clamping unit 2. A clamping block 22 is threadedly connected to the top end of the clamping rod 21. The clamping rod 21 is sleeved with a fixing column 23. The clamping rod 21 is connected to a clamping column 24. A groove 311 is provided on the surface of the clamping column 24. The clamping rod 21 is connected to a connecting shaft 312. This solves the problem that during the stamping operation of the micromotor housing, the housing and the housing cover need to be stamped separately and then assembled after completion. The production speed of the housing is slower than that of the housing cover. The production line for the completed housing cover needs to be added to the production of the housing by replacing the mold to shorten the total production time. The traditional mechanical mold replacement requires a lot of time for disassembly and calibration, which is time-consuming and labor-intensive, takes up a lot of production time, and reduces the production speed.

[0032] In this embodiment, the barrier unit 3 includes:

[0033] The locking assembly 31 is installed at the bottom of the clamping column 24 and is used to lock with the clamping rod 21. The locking assembly 31 includes a groove 311 formed on the surface of the clamping column 24. The bottom end of the clamping rod 21 is fixedly connected with a connecting shaft 312, and the connecting shaft 312 slides inside the groove 311.

[0034] The sliding assembly 32 is mounted on the surface of the clamping rod 21 and is used for the load-bearing installation of the locking assembly 31;

[0035] The limiting assembly 33 is installed on the surface of the clamping rod 21 and is used to improve the stability of the threaded connection between the clamping rod 21 and the clamping block 22 .

[0036] In this embodiment, the sliding assembly 32 includes a sleeve 321 sleeved on the surface of the fixing column 23 , a through slot 322 is formed at the bottom of the clamping column 24 , and the connecting shaft 312 slides inside the through slot 322 .

[0037] In this embodiment, the limiting assembly 33 includes a limiting rod 331 fixedly connected to the surface of the clamping rod 21 , and the limiting rod 331 passes through the surface of the clamping rod 21 and extends. A limiting groove 332 is defined at the bottom end of the fixing column 23 .

[0038] In this embodiment, a support plate 4 is fixedly connected to the inner cavity of the stamping box 1 . A plurality of connection holes 5 are formed on the surface of the support plate 4 . The support plate 4 is fixedly connected to the fixing column 23 through the connection holes 5 .

[0039] In this embodiment, four connecting rods 6 are fixedly connected to the bottom end of the clamping column 24, and the bottom of the four connecting rods 6 is fixedly connected to the die-casting model 7. Through the limit rod 331 on the surface of the clamping rod 21, and the limit rod 331 penetrates the surface of the clamping rod 21 and extends, a limit groove 332 is provided at the bottom end of the fixed column 23, which solves the problem that two unfixed parts connected by threads may slip when rotating, resulting in the inability to disassemble and assemble the mold when replacing the mold, causing time-consuming and labor-intensive problems. It achieves the phenomenon that the parts will not slip when they are threadedly connected, so that the disassembly and assembly can be faster, thereby improving the replacement speed. At the same time, the contents not described in detail in this specification belong to the existing technology known to technical personnel in this field.

[0040] During operation, the punching box 1 is opened, and then the clamping block 22 is rotated. The clamping block 22 causes the clamping rod 21 to slide downward through the thread. The sliding of the clamping rod 21 drives the connecting shaft 312 to slide. When the connecting shaft 312 slides to leave the groove 311, the clamping column 24 is rotated to align the connecting shaft 312 with the through groove 322. Then, the clamping column 24 is slid downward to separate from the clamping rod 21 to complete the disassembly.

[0041] During installation, the clamping column 24 carrying the corresponding mold is aligned with its through groove 322 by the connecting shaft 312, and then the clamping column 24 is slid upward along the clamping shaft. When the connecting shaft 312 slides through the through groove 322 and leaves the bottom end of the clamping column 24, the clamping column 24 is rotated so that the connecting shaft 312 is aligned with the groove 311, and then the clamping block 22 is rotated. The rotation of the clamping block 22 causes the clamping shaft to slide upward through the thread under the limit of the limit shaft. The sliding of the clamping shaft drives the connecting shaft 312 to slide, and then the stamping box 1 is closed to complete the installation.
