Description

Technical Field

[0001] This utility model relates to the technical field of tree-shaped petal columns for airport terminals, specifically a pre-bending fixing frame for petal cone plates. Background Technology

[0002] The terminal building project has 26 pairs of tree-shaped petal columns, of which 9 pairs are 10-limb type and 17 pairs are 6-limb type. The column body (i.e., the trunk) of the tree-shaped column is composed of four-leaf rhomboid cones, i.e., petal cone plates, with concrete poured inside to serve as steel columns.

[0003] The tree-shaped column body is made of high-grade material in the rear half, which is characterized by high bending difficulty and high precision requirements. In order to ensure the bending accuracy of the petal cone plate, the bending process of the petal cone plate is divided into pre-bending and bending. In the pre-bending process, the two long sides of the cone plate need to be bent in sequence. When pre-bending one side of the cone plate, the volume and weight of the cone plate are relatively large. Therefore, the cone plate is not easy to move during the pre-bending process, which causes the bending position to deviate and cannot guarantee the bending accuracy of the cone plate, resulting in low practicality.

[0004] Therefore, this utility model provides a petal cone plate pre-bending fixing bracket. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a petal-shaped cone plate pre-bending fixing bracket to solve the problems mentioned in the background art. This invention uses a handwheel, a first sliding rod, a first screw, and a limiting plate to limit the left end of the cone plate. Simultaneously, an automatic adjustment mechanism, including a servo motor, a second screw, and a second sliding rod, can move the limiting plate, causing it to press against the left end of the cone plate. This facilitates the movement of the cone plate and prevents deviation during the pre-bending process, thus ensuring the accuracy of the petal-shaped cone plate and making it highly practical.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a petal cone plate pre-bending fixing frame, including a lower tire membrane, a bending die is provided at the top of the lower tire membrane through a limiting mechanism, a rotating roller is equidistantly rotatably provided at the top of the other end of the lower tire membrane, a limiting plate is movably provided on one side of the lower tire membrane through an automatic adjustment mechanism, the limiting plate is L-shaped, a first sliding rod is fixedly provided on one side of the bottom end of the limiting plate, the automatic adjustment mechanism includes a second sliding rod, one end of the first sliding rod is limited and slidably disposed inside the second sliding rod, and the top of the limiting plate is disposed on the upper side of the lower tire membrane.

[0007] Furthermore, the lower membrane is U-shaped, and the limiting mechanism includes a placement groove and a limiting rod, with the placement groove located inside the top of the lower membrane.

[0008] Furthermore, the bending die is placed inside the placement groove, and a limiting rod is inserted into one side of the placement groove. One end of the limiting rod is fixedly inserted into the inside of the bending die by a magnet provided inside the bending die.

[0009] Furthermore, both the second slide rod and the first slide rod are square in shape, and the second slide rod is slidably disposed inside one end of the lower fetal membrane.

[0010] Furthermore, the automatic adjustment mechanism also includes a servo motor and a second screw, with the servo motor fixedly disposed inside the other end of the lower tire membrane.

[0011] Furthermore, one end of the second screw is fixed to the output shaft of the servo motor, and the other end of the second screw is screwed into the interior of the other end of the second slide rod.

[0012] Furthermore, a first screw is rotatably mounted inside one end of the second slide rod, and the first screw is screwed into the inside of the first slide rod and the limiting plate. A handwheel is fixedly mounted on the outer end of the first screw.

[0013] Furthermore, a conical plate is placed on top of the bending die and the rotating roller, and the top of the limiting plate is positioned above the conical plate.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a petal-shaped cone plate pre-bending fixing frame. Through a handwheel, a first sliding rod, a first screw, and a limiting plate, the left end of the cone plate can be limited. Simultaneously, an automatic adjustment mechanism, including a servo motor, a second screw, and a second sliding rod, can move the limiting plate, causing it to press against the left end of the cone plate. This facilitates the movement of the cone plate and prevents deviation during pre-bending, thus ensuring the accuracy of the petal-shaped cone plate. The rotating roller reduces friction between the cone plate and the lower membrane, making the cone plate easier to move. Both the first and second sliding rods are square in shape, allowing for mutual limiting and facilitating lateral adjustment of the limiting plate, resulting in high practicality.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a petal cone plate pre-bending fixing frame, including a lower membrane 1. The top end of the lower membrane 1 is provided with a bending mold 2 through a limiting mechanism. The top of the other end of the lower membrane 1 is equidistantly provided with rotating rollers 4. One side of the lower membrane 1 is provided with a limiting plate 5 through an automatic adjustment mechanism 8. The limiting plate 5 is L-shaped. A first sliding rod 6 is fixedly provided on one side of the bottom end of the limiting plate 5. The automatic adjustment mechanism 8 includes a second sliding rod 7. One end of the first sliding rod 6 is limited and slidably disposed inside the second sliding rod 7. The top end of the limiting plate 5 is disposed on the upper side of the lower membrane 1. By adjusting the limiting plate 5, the limiting plate 5 can be brought into contact with and limited to the left end of the cone plate 9. This facilitates the movement of the limiting plate 5 through the automatic adjustment mechanism 8, while simultaneously squeezing the cone plate 9. This allows for precise pre-bending of the cone plate 9, making it highly practical.

[0021] In this embodiment, the lower membrane 1 is U-shaped. The limiting mechanism includes a placement groove and a limiting rod 3. The placement groove is located inside the top of the lower membrane 1. The bending mold 2 is placed inside the placement groove. The limiting rod 3 is inserted into one side of the placement groove. One end of the limiting rod 3 is fixedly inserted into the inside of the bending mold 2 by a magnet provided inside the bending mold 2. The limiting rod 3 can limit the bending mold 2 and can also be disassembled and replaced.

[0022] In this embodiment, both the second slide rod 7 and the first slide rod 6 are square in shape. The second slide rod 7 is slidably disposed inside one end of the lower membrane 1. The automatic adjustment mechanism 8 also includes a servo motor 10 and a second screw 11. The servo motor 10 is fixedly disposed inside the other end of the lower membrane 1. One end of the second screw 11 is fixed to the output shaft of the servo motor 10. One end of the second screw 11 is screwed into the other end of the second slide rod 7. A first screw 12 is rotatably mounted inside one end of the second slide rod 7. The first screw 12 is screwed into the first slide rod 6 and the limiting plate 5. A handwheel 13 is fixedly disposed at the outer end of the first screw 12. The servo motor 10 and the second screw 11 can drive the second slide rod 7 to slide to the right. The second slide rod 7, through the screwing action of the first screw 12 and the first slide rod 6, facilitates the lateral adjustment of the limiting plate 5. The second slide rod 7 and the first slide rod 6 can limit each other, which facilitates the subsequent compression of the cone plate 9.

[0023] In this embodiment, a conical plate 9 is placed on the top of the bending die 2 and the rotating roller 4, and the top of the limiting plate 5 is positioned above the conical plate 9. The rotating roller 4 can reduce the friction between the conical plate 9 and the lower tire film 1, making it easier for the conical plate 9 to move.

[0024] When using this petal-shaped cone plate pre-bending fixing frame, the unbent cone plate 9 is placed on top of the lower mold 1 and the rotating roller 4, and the right end of the cone plate 9 abuts against the bending position of the bending die 2. Rotating the handwheel 13 and the first screw 12, the limiting plate 5 can be adjusted through the screwing action between the first screw 12 and the first sliding rod 6, so that the limiting plate 5 abuts against the left end of the cone plate 9 and limits its movement. This fixing frame is installed below the bending machine, with the bending head of the bending machine facing the bending die 2, and adjusting the cone plate 9... One end is squeezed and bent, while the servo motor 10 is started. The servo motor 10 drives the first slide rod 6 and the first screw 12 through the screwing action between the second screw 11 and the second slide rod 7, and drives the limiting plate 5 to squeeze the cone plate 9 to the right, which facilitates the movement of the cone plate 9 and prevents the cone plate 9 from deviating during the pre-bending process, thereby ensuring the accuracy of the petal cone plate. The rotating roller 4 can reduce the friction between the cone plate 9 and the lower membrane 1, making the cone plate 9 easier to move and highly practical.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
