For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.
[0021] Reference Figures 1 to 4 In the embodiment of the utility model, a large sheet metal stretch forming part correction device includes: an operating table 1, a fixed base plate seat 2 is fixedly connected to one end above the operating table 1, a supporting vertical plate 3 is fixedly connected to one side of the operating table 1, and a supporting vertical plate 2 4 is fixedly connected to the other side of the operating table 1, a motor 5 is fixedly connected to the outer end of the supporting vertical plate 3, a steering long shaft rod 6 is fixedly connected to the output end of the motor 5, and a transmission protrusion 7 is fixedly connected to the outer end of the steering long shaft rod 6. A reciprocating mechanism 8 is provided at one end above the fixed base plate seat 2, and a transmission base plate 9 is provided at the other end above the fixed base plate seat 2. A reset spring 10 is fixedly connected to one end of the back of the transmission base plate 9, and an inverted T-shaped slider 11 is fixedly connected to one end of the bottom of the transmission base plate 9. An arc long block 12 is fixedly connected to one end above the transmission base plate 9, and a fixed base 13 is fixedly connected to one end above the operating table 1.
[0022] Reference Figures 1 to 4The reciprocating mechanism 8 includes a power long box 14, one end of the outer side of the power long box 14 is fixedly connected to a motor 2 15, an output end of the motor 2 15 is fixedly connected to an output shaft 16, one end of the output shaft 16 is fixedly connected to a gear 17, the output shaft 16 is rotationally connected to the power long box 14, the power long box 14 is fixedly connected to the inverted T-shaped slider 11, and the other end of the power long box 14 is fixedly connected to the transmission base plate 9.
[0023] The above solution is adopted: the fixed connection between the power long box 14, the inverted T-shaped slider 11 and the transmission base plate 9 ensures that the reciprocating mechanism 8 has stable structural support when working, reducing errors and failures caused by vibration or external force interference.
[0024] Reference Figures 1 to 4 The inner side of the power long box 14 is rotatably connected with a rotating shaft 18, and one end of the outer side of the rotating shaft 18 is fixedly connected with a gear 2 19, and the gear 1 17 is meshed with the gear 2 19, and the gear 1 17 and the gear 2 19 are both arranged inside the power long box 14.
[0025] With the above solution, gear one 17 and gear two 19 are both located inside the power long box 14. This layout not only protects the gear transmission mechanism from interference and damage from the external environment, but also makes the entire transmission system more compact and efficient.
[0026] Reference Figures 1 to 4 A U-shaped rotating member 20 is fixedly connected to one end of the outer side of the rotating shaft 18 , and a hook 21 is fixedly connected to one end of the U-shaped rotating member 20 .
[0027] By adopting the above scheme: through the combination of the U-shaped rotating member 20 and the hook 21, the device can more flexibly adapt to sheet metal parts of different shapes and sizes. The U-shaped rotating member 20 allows the hook 21 to adjust the angle in multiple directions, thereby realizing multi-angle fixation and correction of the sheet metal parts.
[0028] Reference Figures 1 to 4 A support leg 22 is fixedly connected to one end of the bottom of the operating table 1 , and the support legs 22 are provided in multiple groups and are symmetrically arranged at the bottom of the operating table 1 .
[0029] The above solution is adopted: the design of symmetrically arranged multiple groups of support legs 22 provides stable support and balance for the entire large sheet metal stretch forming part correction device.
[0030] Reference Figures 1 to 4 The steering long shaft rod 6 is rotatably connected to the supporting vertical plate 1 3 , and the other end of the steering long shaft rod 6 passes through the supporting vertical plate 1 3 and is rotatably connected to the supporting vertical plate 2 4 .
[0031] The above solution is adopted: the rotation connection between the steering long shaft rod 6 and the support vertical plate 1 3 and the support vertical plate 2 4 ensures the stability of the transmission system during operation, and reduces the vibration and shaking of the transmission parts through reasonable support and fixation, thereby improving the correction accuracy and reliability.
[0032] Reference Figures 1 to 4 The other end of the return spring 10 is fixedly connected to the operating table 1, and the inverted T-shaped slider 11 is slidably connected to the fixed base plate seat 2.
[0033] Adopt the above scheme: Such a design ensures that the reset spring 10 can quickly return to its original state after being subjected to external force. When the correction device completes a correction action, the reset spring 10 will use its own elastic potential energy to push the relevant components back to the initial position, preparing for the next correction operation. This automatic reset function not only improves work efficiency, but also reduces the labor intensity of operators.
[0034] The working principle of the utility model is as follows: when in use, a large sheet metal stretch forming part is placed on a fixed bottom plate seat 2, ready for correction operation, the output shaft 16 and the gear 17 are driven to rotate by the motor 2 15, and the rotating shaft 18 is driven to rotate by the gear 2 19, so that the U-shaped rotating part 20 is rotated, and the angle of the hook 21 can be adjusted to hook or press the sheet metal part to achieve the fixation and positioning of the sheet metal part, and it can adapt to sheet metal parts of different shapes and sizes. The angle and position of the hook 21 can be adjusted to achieve the fixation and correction of various sheet metal parts, and then the steering long shaft rod 6 is driven to rotate by starting the motor 15, and the transmission protrusion 7 is driven to rotate. During the rotation process, when the convex part of the transmission protrusion 7 touches the arc surface long block 12 When the arc surface long block 12 is rotated, a thrust or impact force is applied to the transmission base plate 9, and then the inverted T-shaped slider 11 and the fixed base plate seat 2 are connected to make the inverted T-shaped slider 11 and the transmission base plate 9 perform a linear motion 1 above the fixed base plate seat 2. When the raised part of the transmission protrusion 7 temporarily does not contact the arc surface long block 12 during the rotation process, the return spring 10 pushes the transmission base plate 9 back, thereby realizing reciprocating linear motion. This method can perform highly accurate correction on large sheet metal stretch forming parts, ensuring that the size and shape of the formed parts meet the design requirements, improving the quality and reliability of the products, and making the operation process more efficient, greatly reducing the tediousness of manual operation, and improving the stability and accuracy of the operation.
