[0018] Example 1

[0019] like Figures 1-5 As shown in the figure, the shell stamping forming device proposed in this embodiment includes a frame 1, a turntable 2, an upper die base 7, an automatic rotation mechanism, a transmission mechanism, and multiple lower die bases 3.

[0020] The frame 1 is connected to a first mounting bracket 5 and a second mounting bracket 12; the turntable 2 is rotatably mounted on the frame 1, and the turntable 2 has multiple material feeding holes 201; the lower die base 3 is provided with at least three, so that the device has at least three workstations for feeding, stamping and unloading; L-shaped limiting parts 27 are provided around the lower die base 3.

[0021] Rotary seats 28 are provided on both sides of the lower mold base 3. The rotating seats 28 are fixed on the turntable 2. Mounting shafts 29 are connected to both ends of the lower mold base 3. The two mounting shafts 29 are rotatably mounted on the rotating seats 28 on both sides respectively. An elastic mechanism for driving the mounting shaft 29 to automatically reset is installed on one side of the rotating seat 28. The elastic mechanism includes a spring 31 and a mounting sleeve 30. The mounting sleeve 30 is mounted on the rotating seat 28. The spring 31 is mounted inside the mounting sleeve 30 and is connected to the mounting shaft 29. A limit block 8 is connected to the side of the lower mold base 3.

[0022] The automatic rotation mechanism includes a guide plate 9 and multiple sets of drive components. The guide plate 9 is connected to the outer wall of the frame 1. The guide plate 9 has an outward bending structure. Multiple lower mold bases 3, multiple material discharge holes 201, and multiple sets of drive components are all set one-to-one. The drive mechanism components include a first rack 24, a push rod 25, and a third gear 26. The third gear 26 is mounted on the corresponding side mounting shaft 29. The first rack 24 is slidably mounted on the turntable 2 and meshes with the third gear 26. The push rod 25 is connected to the first rack 24.

[0023] The upper mold base 7 is located above the turntable 2, and a hydraulic cylinder 6 for driving the upper mold base 7 to rise and fall is installed on the first mounting bracket 5.

[0024] The transmission mechanism converts the downward movement of the upper mold base 7 into the rotational movement of the turntable 2, while the turntable 2 remains stationary when the upper mold base 7 moves upward. The transmission mechanism includes a first gear 10, a second gear 11, a first bevel gear 13, a second bevel gear 15, a damping shaft 16, a ratchet 17, a rotating ring 18, a gear ring 19, a second rack 34, and a vertical rod 35. The first gear 10 is fixed at the bottom center of the turntable 2, and a second mounting bracket 12 is fixed at the bottom of the frame 1. The second gear 11 is rotatably mounted on the second mounting bracket 12 and meshes with the first gear 10. The first bevel gear 13 meshes with the second gear 15. The shaft of gear 11 is connected, the damping shaft 16 is rotatably mounted on the second mounting bracket 12, the second bevel gear 15 and ratchet 17 are respectively connected to the two ends of the damping shaft 16, the second bevel gear 15 is meshed with the first bevel gear 13, the rotating ring 18 is rotatably mounted on the second mounting bracket 12 and located outside the ratchet 17, the rotating ring 18 is provided with a mounting groove 181, the end of the wedge block 32 is slidably mounted in the mounting groove 181, the spring 33 is mounted in the mounting groove 181, the toothed ring 19 is mounted on the outer circumference of the rotating ring 18, and the second rack 34 is fixedly connected to the upper mold base 7 through the vertical rod 35.

[0025] Furthermore, this technical solution also includes a PLC controller, which is used for equipment control and data processing.

[0026] In this embodiment, the metal sheet is placed on the lower die base 3. Multiple L-shaped limiting members 27 are used to limit the metal sheet to be stamped, preventing it from shifting. The hydraulic cylinder 6 is activated, driving the upper die base 7 downwards. The upper die base 7 drives the second rack 34 to move. When the second rack 34 contacts the gear ring 19, the vertical motion of the second rack 34 is converted into the rotational motion of the gear ring 19. The gear ring 19 drives the rotating ring 18 to rotate, which in turn drives the wedge block 32 to rotate around its center. The wedge block 32 is engaged in the groove of the ratchet 17, which in turn drives the ratchet 17 to rotate. The damping shaft 16, the second bevel gear 15, and the first bevel gear 13... Under the transmission action of the second gear 11, the rotation of the ratchet 17 can be converted into the rotation of the first gear 10. The first gear 10 then drives the turntable 2 to rotate. When the second rack 34 moves below the gear ring 19 and separates from the gear ring 19, the turntable 2 stops rotating. The lower die base 3 carrying the metal sheet moves to the direct below the upper die base 7. At this time, the upper die base 7 is not in contact with the metal sheet. As the upper die base 7 continues to move downward, it closes with the lower die base 3 to complete the stamping of the metal sheet. It should be noted that when the second rack 34 is driven to move upward, the gear ring 19 will move in the opposite direction. At this time, the wedge block 32 will not drive the ratchet 17 to rotate during the rotation.

[0027] As the turntable 2 continues to rotate, when the push rod 25 contacts the bent part of the guide plate 9, the push rod 25 gradually moves closer to the center of the turntable 2 during rotation. The movement of the push rod 25 drives the first rack 24 to move, and the movement of the first rack 24 can drive the third gear 26 to rotate, thereby driving the mounting shaft 29 and the lower die base 3 to rotate. This realizes the automatic flipping of the lower die base 3, which is used to assist in the automatic unloading of the stamped workpiece. Furthermore, a belt conveyor can be installed in the unloading area to transport the product.

[0028] After the push rod 25 separates from the guide plate 9, the mounting shaft 29 is driven to rotate and reset under the elastic force of the spring 31. During this process, the mounting shaft 29 drives the lower mold base 3 to rotate. After the limit block 8 is pressed against the turntable 2, the lower mold base 3 stops rotating.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a shell stamping forming device is proposed. Compared with the first embodiment, in this embodiment, a connecting plate 23 is connected to the upper mold base 7, and a pin 22 is vertically connected to the connecting plate 23. The lower end of the pin 22 is a conical structure. A disc 4 is fixed in the middle of the turntable 2. The disc 4 has multiple positioning holes 401 that correspond one-to-one with multiple material feeding holes 201. When the second rack 34 separates from the toothed ring 19, the pin 22 is located above the positioning hole 401 on the corresponding side. If there is a slight angular deviation between the pin 22 and the positioning hole 401 due to the transmission action of the transmission component, the automatic correction work of the upper mold base 7 and the lower mold base 3 can be completed when the bottom tip of the pin 22 is fully inserted into the inside of the positioning hole 401. At this time, the upper mold base 7 is not in contact with the metal sheet.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
