[0001] The utility model relates to the field of forming equipment, in particular to a high-strength automobile motor housing forming equipment. Background Art

[0002] The high-strength automobile motor housing is a key component in the electric drive system of new energy vehicles. It mainly plays an important role in protecting the motor, maintaining the internal temperature stability of the motor, and improving the overall performance of the motor. The forming equipment of the high-strength automobile motor housing usually includes a variety of machine tools and processing equipment, and these equipment cooperate with each other to complete the precise processing and forming of the motor housing. For example, the numerical control lathe is one of the commonly used equipment in the processing of the motor housing. It can precisely cut and process the housing material according to the preset program. For the high-strength automobile motor housing, the high precision and stability of the numerical control lathe are particularly important to ensure the dimensional accuracy and surface quality of the housing.

[0003] When the existing housing is formed and demolded, the mold may move along with the housing. This relative movement between the mold and the housing may cause unnecessary mechanical stress on the housing, resulting in deformation, cracks or even fractures of the housing. This will not only affect the appearance quality of the housing, but also seriously damage its structural integrity and service performance. At the same time, this movement may also mean that the mold itself may be damaged, such as wear, deformation or fracture, which will reduce the production efficiency.

[0004] Therefore, aiming at the problem that when the existing housing is formed and demolded, the mold may move along with the housing, this relative movement between the mold and the housing may cause deformation, cracks or even fractures of the housing, affecting the appearance quality of the housing, and at the same time, the mold itself may also be damaged, which will reduce the production efficiency, a high-strength automobile motor housing forming equipment can be designed, and a fixed limit structure is arranged outside the mold to prevent the mold from moving.

[0025] Please refer to Figure 3, in this embodiment, second columns 201 are installed at the lower end of the operation table 2 near the corners. After the shell is formed, according to the size of the lower template 307, through the adjustment of the positioning pin 204 and driven by the second motor 209, the threaded rod 208 rotates, causing the rectangular threaded sleeve 207 to drive the L-shaped telescopic sleeve 203 to move along the rectangular chute 202. A plurality of groups of positioning holes 206 are horizontally spaced above the rectangular telescopic plate 205. During the movement of the L-shaped telescopic sleeve 203, the rectangular telescopic plate 205 contracts along the L-shaped telescopic sleeve 203 until the inner wall of the L-shaped telescopic sleeve 203 fits the outside of the lower template 307. After confirmation, the positioning pin 204 passes through the L-shaped telescopic sleeve 203 and is fixedly connected to the rectangular telescopic plate 205 through the positioning hole 206, thereby limiting and fixing the lower template 307.

[0026] Please refer to Figures 4-5 , in this embodiment, the forming assembly includes a hydraulic column 301, a hydraulic cylinder 302, a clamping hole 303, a connecting block 304, a clamping column 305, an upper template 306, a lower template 307, a circular telescopic column 308, a circular telescopic sleeve 309, and a cylinder 310.

First, take out the required upper template 306 and lower template 307, then place the lower template 307 on the operation table 2 corresponding to the circular telescopic column 308, and then the clamping column 305 drives the connecting block 304 to be fixedly connected to the hydraulic column 301 through the clamping hole 303, thereby assembling the upper template 306 and the hydraulic column 301. The upper template 306 is installed at the lower end of the connecting block 304, the lower template 307 is provided below the upper template 306, the circular telescopic column 308 passes through the middle of the lower template 307, the circular telescopic column 308 passes through the operation table 2 and is movably connected thereto, the circular telescopic sleeve 309 is sleeved outside the circular telescopic column 308, the circular telescopic sleeve 309 passes through the bearing platform 1 and is fixedly connected thereto, and the cylinder 310 is installed at the lower end of the circular telescopic sleeve 309. Pour the materials required for making the shell into the lower template 307, and then driven by the hydraulic cylinder 302, the hydraulic column 301 drives the upper template 306 to press downward, causing the shell to be formed. When the shell is formed and cooled, driven by the cylinder 310, the circular telescopic column 308 pushes the formed shell upward along the circular telescopic sleeve 309.

[0027] When working, first take out the required upper template 306 and lower template 307. Then place the lower template 307 on the operating table 2, corresponding to the circular telescopic column 308. Then the clamping column 305 drives the connecting block 304 to be positioned and connected with the hydraulic column 301 through the clamping hole 303, thereby assembling the upper template 306 and the hydraulic column 301. Immediately afterwards, pour the materials required for making the shell into the lower template 307. Then, driven by the hydraulic cylinder 302, the hydraulic column 301 drives the upper template 306 to press downwards, causing the shell to be formed. After the shell is formed, driven by the first motor 103, the rotating shaft 106 drives the fan blade 107 to rotate along the rotating ring sleeve 105 to form wind, driving the air flow to pass through the installation holes and cool the shell;

[0028] During the cooling process, according to the size of the lower template 307, through the adjustment of the positioning pin 204, driven by the second motor 209, the threaded rod 208 rotates, causing the rectangular threaded sleeve 207 to drive the L-shaped telescopic sleeve 203 to move along the rectangular chute 202. During this process, the rectangular telescopic plate 205 contracts along the L-shaped telescopic sleeve 203 until the inner wall of the L-shaped telescopic sleeve 203 fits the outside of the lower template 307. After confirmation, the positioning pin 204 passes through the L-shaped telescopic sleeve 203 and is positioned and connected with the rectangular telescopic plate 205 through the positioning hole 206, thereby limiting and fixing the lower template 307. Then, driven by the cylinder 310, the circular telescopic column 308 pushes the formed shell upwards along the circular telescopic sleeve 309.

[0029] Through the above steps, first take out the required molds. After assembly, perform the shell forming operation on the operating table 2. When the shell is formed, the L-shaped telescopic sleeve 203 and the rectangular telescopic plate 205 on the operating table 2 cooperate with each other to contract, limiting and fixing the molds, preventing the molds from moving with the shell when the shell is demolded. This can effectively avoid this situation, protect the integrity and service life of the molds, and at the same time ensure that the shell receives uniform force during the forming process, thereby improving the dimensional accuracy and surface quality of the product. Also, the stable molds reduce the downtime for maintenance due to mold movement, thus improving the production efficiency of the entire production line, so as to solve the problem that in the existing shell forming and demolding, the mold may move with the shell, and this relative movement between the mold and the shell may cause the shell to deform, crack or even break, affecting the appearance quality of the shell, and at the same time the mold itself may also be damaged, which will reduce the production efficiency.
