They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0044] like Figures 1-7 As shown, in this embodiment, the motor housing forming device includes an upper die 1, a lower die 2, a punching and bending mechanism 3, a fixed guide pin 4, a cutting mechanism 5, and a core-pulling forming mechanism 6. The punching and bending mechanism 3 is located between the upper die 1 and the lower die 2. The punching and bending mechanism 3 includes a rolling guide post 31, a first insert 32, and a second insert 33. The rolling guide post 31 is rotatably mounted on the upper die 1 and rotatably engages with the lower die 2. The first insert 32 is mounted on the upper die 1, and the second insert 33 is mounted on the lower die 2. The first insert 32 is pressed against the second insert 33. The fixed guide pin 4 has an irregular shape, and there are multiple fixed guide pins 4, which are respectively mounted on the upper die 1 and the lower die 2. The cutting mechanism 5 is located between the upper die 1 and the lower die 2 and is used to separate the housing. The core-pulling forming mechanism 6 is located between the upper die 1 and the lower die 2, and is positioned between the punching and bending mechanism 3 and the cutting mechanism 5. The core-pulling forming mechanism 6 is used for core-pulling forming of the housing. Specifically, the upper die 1 consists of an unloading plate 7, an unloading pad, a punch plate, an upper pad, an upper die 1 base, and an upper cover plate. The lower die 2 consists of a base plate, equal-height pads, a lower die 2 base, a lower pad, and a concave plate. The upper die 1 and lower die 2 are guided by rolling guide pillars 31. Compared with traditional sliding guide pillars, the rolling guide pillars 31 have higher guiding accuracy, improved die precision, and simpler and more convenient die installation, maintenance, and machine type switching. Compared with traditional movable guide pillars, the fixed guide pins 4 have a larger contact surface with the material strip and a greater effective elastic sensing effect, resulting in higher guiding accuracy. Each stamping can play a guiding and positioning role, allowing for free switching between multiple machine types and specifications of parts to produce different length specifications. If the fixed guide pin 4 and the guide strip are not at the set step distance during the feeding process, the compression of the fixed guide pin 4 is transmitted to the sensor 8, and the working equipment stops running. It is necessary to manually adjust the feeding step distance to restore normal operation. The upper die 1 then completes the stamping work downwards. The fixed guide pin 4 sequentially performs positioning punching, positioning bending, and rolling forming on the motor housing. The core-pulling forming mechanism 6 is used to pull and shape the core of the motor housing. The parts in the cavity can be freely and quickly switched to produce products of different specifications and lengths. The cutting mechanism 5 is used to separate the motor housing and the forming device.
[0045] The working principle of the motor housing forming device is as follows: The device is installed on the equipment, the feeder loads the material of the specified specification and adjusts the step distance, and feeds the material to the device. Under the action of the punching and bending mechanism 3, the guide hole and the die hole are punched. The fixed guide pin 4 sequentially positions the long end face of the motor housing, punches the side opening, positions the bending, and positions the rolling. Then, the core-pulling forming mechanism 6 pulls the core of the motor housing and shapes it. The parts in the cavity can be freely and quickly switched to produce machine products of different specifications and lengths. The cutting mechanism 5 is used to separate the motor housing and the forming device.
[0046] Furthermore, continue to refer to Figures 1-7 The motor housing forming device also includes a stripper plate 7, which is disposed on the upper die 1. The punching and bending mechanism 3 also includes a shaped floating pin 34, which is disposed on the lower die 2. The shaped floating pin 34 can press against the stripper plate 7. Specifically, there are multiple shaped floating pins 34, which are spaced apart along the length of the lower die 2. Under the action of the punch, the outer rolling guide post 31 guides the upper die 1 to work downward. The rolling guide post 31 guides the cavity of the upper die 1 to work downward. The feeder feeds the material according to the set size. The stripper plate 7 contacts the shaped floating pin 34. The fixed guide pin 4 and the shaped floating pin 34 support the material strip downward. The stripper plate 7 contacts the concave die and presses the material strip. During the upward compression process, the stripper plate 7... The first insert 32 presses down and the second insert 33 to perform a stamping action until the stripper plate contacts the punch fixing plate. The stroke is completed when the stripper plate contacts the punch fixing plate. Under the action of the punch press, the upper die 1 starts to work upward. The stripper plate 7 works downward under the elastic force of the upper die 1. When the stripper plate 7 completes its action, it separates from the die plate and moves upward at the same time as the upper die 1. The irregular floating pin 34 and the material support belt return to their original positions. Under the action of the punch press, this action is repeated to complete continuous stamping to form the punch guide hole and the punch hole.
[0047] Furthermore, continue to refer to Figures 1-7The core-pulling forming mechanism 6 includes a cylinder 61, a first elastic element 62, a forming die 63, and a forming core 64. The forming die 63 is disposed between the upper die 1 and the lower die 2. The first elastic element 62 is disposed on the lower die 2. The cylinder 61 is elastically connected to the first elastic element 62. The forming core 64 is disposed at the output end of the cylinder 61. Under the driving action of the cylinder 61, the forming core 64 can pull the outer shell inside the forming die 63 to form the core. Specifically, the core-pulling forming mechanism 6 also includes a second elastic element 65, a third elastic element 66, and an extension pressure plate 67. The second elastic element 65 is disposed on the lower mold 2 and connected to the forming die 63. The third elastic element 66 is disposed on the upper mold 1. One end of the extension pressure plate 67 is disposed on the upper mold 1, and the other end of the extension pressure plate 67 is disposed between the output end of the cylinder 61 and the third elastic element 66. The first elastic element 62, the second elastic element 65, and the third elastic element 66 are all nitrogen springs, which makes the roundness, symmetry, and parallelism of the outer shell more stable. The working principle of the core-pulling forming mechanism 6 is as follows: Under the action of the punch press, the upper die 1 works downward, the feeder feeds the material according to the set size, the upper die 1 continues to move downward, the cylinder 61 on the movable plate of the core fixing seat pushes the forming core 64 parallel to the limit movable plate, the upper die 1 continues to move downward to the upper forming die, and contacts the material strip to start forming. The upper die 1 continues to move downward, under the uniform force of the equal height adjustment block on the nitrogen spring, the extension pressure plate 67 pushes against the movable plate of the core fixing seat, the forming core 64 and the cylinder 614 are under force and move downward steadily until the upper forming die and the lower forming die contact and merge, the upper die 1 moves downward, the stripper plate 7 moves upward, the upper die 1 is compressed downward to the bottom dead point of the die, until the motor housing is completely fixed and formed, the above actions are repeated under the action of the punch press to complete the continuous punching.
[0048] Preferably, there are multiple rolling guide pillars 31, which are arranged in an array between the upper mold 1 and the lower mold 2.
[0049] Furthermore, continue to refer to Figures 1-7 The cutting mechanism 5 includes a cutting punch 51, a stripper insert 52, a wedge 53, and a slider 54. The cutting punch 51 is disposed on the upper die 1, the stripper insert 52 is sleeved on the cutting punch 51, the slider 54 is disposed on the lower die 2, and the two ends of the wedge 53 are respectively disposed between the cutting punch 51 and the slider 54. Specifically, the cutting punch 51, the stripper insert 52, the wedge 53, and the slider 54 are machines that can freely switch between various specifications and models of parts to produce different lengths, and machines that can freely and quickly switch between producing parts of different lengths within the cavity.
[0050] Furthermore, continue to refer to Figures 1-7The motor housing forming device also includes a sensor 8, which is located on the lower die 2. The sensor 8 is used to detect the elastic force of the fixed guide pin 4 on the material strip. Specifically, the sensor 8 is used for automatic detection and shutdown of feeding deviation. When the compression of the fixed guide pin 4 is transmitted to the sensor 8, the working equipment stops running. It is necessary to manually adjust the feeding pitch to restore normal operation, and the upper die 1 completes the stamping work downward.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
