Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and more specifically, to a petal column, a manufacturing method thereof, and a construction process thereof. Background Art

[0002] As a building decoration component, petal columns are widely used in places such as garden landscapes, city squares, and railway platforms. Traditional petal columns are mostly made of concrete or stone, with a single shape, large weight, and high construction difficulty. With the development of modern building technology, metal materials are gradually applied to the manufacture of petal columns, which not only reduces the weight but also improves the diversity and aesthetics of the shape.

[0003] Railway platforms are usually in an open environment with excellent ventilation conditions. However, in strong wind weather, the petal columns on railway platforms are easily affected by strong winds, and moreover, strong train winds are generated when trains pass quickly, both of which are likely to cause strong airflows to impact the petal columns, generating a large lateral force on the column structure of the petal columns, and easily increasing the risk of structural deformation or even damage to the petal columns;

[0004] During the manufacturing process of petal columns, due to the complex structure of the flower-shaped plates on the outer side of the petal columns, with many curved surfaces and a complex contour shape of the flower-shaped plates, when manufacturing the flower-shaped plates, a stamping machine is usually used to stamp a heated steel plate into the shape of the flower-shaped plates. However, there are still redundant scraps at the contour of the flower-shaped plates after stamping, and the contour of the flower-shaped plates needs to be cut and corrected by a cutting machine, which is rather troublesome, and the complex contour shape of the flower-shaped plates leads to a greater operation difficulty in the subsequent cutting and correction. In view of this, we propose a petal column, a manufacturing method thereof, and a construction process thereof. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the flower-shaped plate is designed as a plate structure with a three-dimensional curved surface, and the curved surfaces with opposite bending directions are tangent and transitioned, so that the airflow flows more smoothly on the surface of the flower-shaped structure, reducing the direct impact of the airflow. The curved surface transition with opposite bending directions can guide the airflow to disperse in different directions, reducing the influence of the wind pressure on the structure, thereby improving the wind resistance performance. Further, hemispherical arc-shaped plates are integrally formed on the side wall of the flower-shaped plate, and arc-shaped plates are integrally formed on the side wall of the vertical stiffening plate. The combination of a plurality of hemispherical arc-shaped plates and a plurality of arc-shaped plates forms a spherical structure. Through the spherical structure, strong winds can be dispersed in different directions, avoiding the concentrated action of the wind force on a certain local area, making the airflow flow smoothly and evenly on its surface, and not easily generating strong airflow impacts, significantly improving the wind resistance performance and stability of the petal column.

[0016] 2. In the present invention, by designing air guiding holes and air guiding channels, after a spherical structure is formed by combining a plurality of hemispherical arc-shaped plates and a plurality of arc-shaped plates, when strong winds blow towards the surface of the spherical structure, a part of the airflow can blow into the interior of the hemispherical arc-shaped plate through the air guiding holes, and the airflow is guided to the air guiding holes of other hemispherical arc-shaped plates through the air guiding channels for discharge, forming a drainage and evacuation effect on the airflow in strong wind weather, reducing the impact of the airflow on the petal column, and further solving the problem that when strong winds impact the petal column, it is easy to increase the risk of structural deformation or even damage of the petal column.

[0017] 3. The present invention arranges a first oblique cutting component and a second oblique cutting component on two inclined plane structures of the lower die of a stamping device respectively, and arranges a first straight cutting component and a second straight cutting component on two vertical plane structures respectively. Through the special shape design of the upper die and the lower die, the blank can be accurately stamped into a flower-shaped plate. Then, through the linkage operation of the first oblique cutting component, the second oblique cutting component, the first straight cutting component and the second straight cutting component, the outer contour of the flower-shaped plate after stamping can be quickly and accurately cut and shaped, reducing the subsequent cutting and correction steps, simplifying the manufacturing process. The oblique cutting component and the straight cutting component in the stamping device can work in linkage to ensure the accurate shaping of the contour of the flower-shaped plate, improving the production efficiency and solving the technical problem of the large difficulty in contour correction of the stamped flower-shaped plate.

[0018] 4. The present invention enables the first straight cutting component and the second straight cutting component to follow the cutting action of the first oblique cutting component in linkage. By using the transmission mode of a gear and a rack, the precise cooperation between components is realized, reducing the use of separate driving devices, lowering the equipment cost and energy consumption. At the same time, the synchronism and accuracy of the cutting action are ensured, realizing the all-round synchronous cutting and shaping of the outer contour of the flower-shaped plate, significantly improving the processing precision and efficiency.

[0019] 5. The present invention designs a waste material baffle, a guide plate and a shaking component. When the first punch moves, the toothed plate on the side wall of the first punch meshes with the fifth gear, driving the fifth gear to rotate. The fifth gear drives the sixth gear to rotate, and the sixth gear drives a plurality of eccentric wheels connected coaxially to rotate. The plurality of eccentric wheels perform eccentric rotational motion, generating an intermittent thrust on the bottom of the waste material baffle, causing the waste material baffle to swing. The waste material baffle can shake the waste material that may remain on its surface, keeping the surface of the waste material baffle clean. Moreover, during the swinging process of the waste material baffle, it drives the percussion rod to strike the top of the guide plate, causing the guide plate to vibrate and shaking the waste material that may remain on the surface of the guide plate, keeping the surface of the guide plate clean. Through the cooperation of the shaking component with the waste material baffle and the guide plate, the waste material generated during the cutting process and remaining on the surfaces of the waste material baffle and the guide plate can be effectively shaken off, preventing the accumulation of waste material from affecting the subsequent cutting work, and at the same time reducing the workload of manual waste material cleaning and improving the production efficiency.

[0046] Example 1, as Figures 1 to 4 shown, a petal column involved in the present invention includes a plurality of flower-shaped plates 1, a plurality of vertical stiffening plates 2 and a reducing circular tube 3. The plurality of vertical stiffening plates 2 are arranged in a circular array on the circumferential outer wall of the reducing circular tube 3, and each two vertical stiffening plates 2 are connected by a flower-shaped plate 1.

[0047] In the embodiment of the present invention, the plurality of flower-shaped plates 1 are arranged in a circular array. The flower-shaped plate 1 is a plate-shaped structure with a three-dimensional curved surface, and the curved surfaces are tangent and transition with opposite bending directions. This design can effectively disperse external stresses (such as wind force, gravity, etc.), avoid stress concentration, and thus improve the stability and anti-deformation ability of the overall structure. The plurality of flower-shaped plates 1 are combined to form a flower-shaped structure. When the plurality of flower-shaped plates 1 are combined to form a flower-shaped structure, the plates are tightly connected through the curved surface transition and support each other, further enhancing the stability and load-bearing capacity of the overall structure. Moreover, this flower-shaped structure imitates the shape of flowers in nature, has high artistic and ornamental value, can be harmoniously integrated with the surrounding environment, and enhances the overall aesthetic feeling of the building.

[0048] Furthermore, the variable-diameter circular tube 3 is used to provide stable support for the flower-shaped plate 1 and the vertical stiffening plate 2; a hemispherical arc panel 101 is integrally formed on the side wall of the flower-shaped plate 1; an arc-shaped plate 201 is integrally formed on the side wall of the vertical stiffening plate 2, and the radian of the side wall of the arc-shaped plate 201 is the same as that of the side wall of the hemispherical arc panel 101. A spherical structure is formed by combining multiple hemispherical arc panels 101 and multiple arc-shaped plates 201; when there is strong wind weather, the spherical structure can make the airflow flow smoothly and evenly on its surface, and it is not easy to generate strong airflow impact; in the present invention, the flower-shaped plate 1 is designed as a plate-like structure with a three-dimensional curved surface, and the curved surfaces are tangent and transition with opposite bending directions, so that the airflow flows more smoothly on the surface of the flower-shaped structure, reducing the direct impact of the airflow. The transition of the curved surfaces with opposite bending directions can guide the airflow to disperse in different directions, reducing the influence of wind pressure on the structure, thereby improving the wind resistance performance. Further, a hemispherical arc panel 101 is integrally formed on the side wall of the flower-shaped plate 1, and an arc-shaped plate 201 is integrally formed on the side wall of the vertical stiffening plate 2. A spherical structure is formed by combining multiple hemispherical arc panels 101 and multiple arc-shaped plates 201. The spherical structure can disperse the strong wind in different directions, preventing the wind force from concentrating on a certain local area, making the airflow flow smoothly and evenly on its surface, and not easy to generate strong airflow impact, significantly improving the wind resistance performance and stability of the petal column.

[0049] Still further, a plurality of air guiding holes 102 are formed on the side wall of the hemispherical arc panel 101, and an air guiding channel is formed between the vertical stiffening plate 2 and the arc-shaped plate 201; in the present invention, by designing the air guiding holes 102 and the air guiding channel, after a spherical structure is formed by combining multiple hemispherical arc panels 101 and multiple arc-shaped plates 201, when the strong wind blows towards the surface of the spherical structure, a part of the airflow can blow into the interior of the hemispherical arc panel 101 through the air guiding holes 102, and the airflow is guided to the air guiding holes 102 of the other multiple hemispherical arc panels 101 through the air guiding channel for discharge, forming a drainage and evacuation effect on the airflow in strong wind weather, reducing the impact of the airflow on the petal column, and further solving the problem that when the strong wind impacts the petal column, it is easy to increase the risk of deformation or even damage to the petal column structure.

[0055] Example 3, as Figures 5 to 18 shown, the present invention relates to a stamping device, including a stamping device 4. The stamping device 4 includes an upper mold 5, a lower mold 6 and a hydraulic system. Among them, the hydraulic system is the prior art in the stamping device 4.

Since the bottom of the upper mold 5 is set to have the same shape as the inner side wall of the flower-shaped plate 1, and the top of the lower mold 6 is set to have the same shape as the outer side wall of the flower-shaped plate 1, when the upper mold 5 and the lower mold 6 are closed, the metal plate blank is stamped to be initially formed into the flower-shaped plate 1.

[0056] Furthermore, the first bevel cutting component 71 and the second bevel cutting component 72 are mutually symmetrical structural components, and the first bevel cutting component 71 and the second bevel cutting component 72 can punch out the excess plate material of the stamped flower modeling plate 1 along the inclined surface structure direction of the lower mold 6, and the first straight cutting component 73 and the second straight cutting component 74 can follow the punching action of the first bevel cutting component 71 to perform vertical upward punching on the vertical surface structure, so as to achieve the effect of punching and shaping the outer edge contour of the stamped flower modeling plate 1; the present invention arranges the first bevel cutting component 71 and the second bevel cutting component 72 on the two inclined surface structures of the lower mold 6, and arranges the first straight cutting component 73 and the second straight cutting component 74 on the two vertical surface structures, and through the special shape design of the upper mold 5 and the lower mold 6, the blank can be accurately stamped into the flower modeling plate 1, and then the first bevel cutting component 71, the second bevel cutting component 72, the first straight cutting component 73 and the second straight cutting component 74 work in conjunction, so that the stamped flower modeling plate 1 can be quickly and accurately The outer edge contour is punched and shaped, which reduces the steps of subsequent cutting and correction, simplifies the manufacturing process, and the bevel cutting component and the straight cutting component in the stamping equipment can work in conjunction to ensure that the contour of the flower shaping plate 1 is accurately formed, improves production efficiency, and solves the technical problem of the difficulty of correcting the contour of the stamped flower shaping plate 1.

The output end of the hydraulic cylinder 706 penetrates through the top of the fixing frame 701 and is connected to a first punching knife 707. The first punching knife 707 is movably arranged between the function frame 704 and the lower die 6. A plurality of movable grooves 708 are formed in the side wall of the first punching knife 707, and the convex blocks 705 are arranged in the movable grooves 708. A limiting plate 709 is connected to the side wall of the first punching knife 707. The limiting plate 709 is of a concave plate-like structure. When the first punching knife 707 punches upward along the inclined surface, the top of the limiting plate 709 contacts the bottom of the convex block 705 to limit the bevel cutting stroke of the first punching knife 707.

When the first punching knife 707 punches upward along the inclined surface, the top of the limiting plate 709 contacts the bottom of the convex block 705 to limit the bevel cutting stroke of the first punching knife 707 and ensure the accuracy of punching. At the same time, the first rack 711 and the second rack 712 on the side wall of the first punching knife 707 move along with the movement of the first punching knife 707.
