[0002] As a kind of architectural decorative component, petal columns are widely used in garden landscapes, city squares, railway platforms and other places. Traditional petal columns are mostly made of concrete or stone, with a single shape, heavy weight and high construction difficulty. With the development of modern construction technology, metal materials are gradually used in 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 located in an open environment with excellent ventilation conditions. However, in strong wind weather, the petal columns of railway platforms are easily affected by strong winds. In addition, strong train winds will be generated when trains pass quickly, which can easily cause strong airflow to impact the petal columns and generate large lateral forces on the column structure of the petal columns, which can easily increase the risk of deformation or even damage of the petal column structure. In the process of manufacturing the petal column, since the flower modeling plate on the outside of the petal column has a complex structure, many curved surfaces, and a complex contour shape, a punching machine is usually used to punch the heated steel plate into the shape of the flower modeling plate. However, there are still excess scraps in the contour of the flower modeling plate after stamping, and the contour of the flower modeling plate needs to be cut and corrected by a cutting machine, which is troublesome. In addition, the contour shape of the flower modeling plate is complex, which makes the subsequent cutting and correction operation difficult. In view of this, we propose a petal column, a manufacturing method and a construction process thereof. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention designs the flower-shaped plate as a plate-like structure with a three-dimensional curved surface, and the curved surface is a tangent transition of the curved surfaces in 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 curved surface transition in opposite bending directions can guide the airflow to disperse in different directions, reduce the influence of wind pressure on the structure, and thus improve the wind resistance. Furthermore, a hemispherical arc panel is integrally formed on the side wall of the flower-shaped plate, and an arc panel is integrally formed on the side wall of the vertical stiffening plate. A plurality of hemispherical arc panels and a plurality of arc panels are combined to form a spherical structure. The spherical structure can disperse strong winds in different directions, avoid the wind force from being concentrated on a certain local area, make the airflow flow smoothly and evenly on its surface, and not easily produce strong airflow impact, thereby significantly improving the wind resistance and stability of the petal column.

[0014] 2. The present invention designs air ducting holes and air ducting channels, and combines multiple hemispherical arc panels with multiple arc plates to form a spherical structure. When strong wind blows toward the surface of the spherical structure, a part of the airflow can be blown into the interior of the hemispherical arc panels through the air ducting holes, and the airflow is guided to the air ducting holes of the other multiple hemispherical arc panels through the air ducting channels for discharge, thereby 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 risk of deformation or even damage of the petal column structure when strong winds impact the petal column.

[0015] 3. The present invention arranges the first bevel cutting component and the second bevel cutting component on the two inclined surface structures of the lower die of the stamping equipment, and arranges the first straight cutting component and the second straight cutting component on the two vertical surface structures. Through the special shape design of the upper die and the lower die, the blank can be accurately stamped into a flower shaped plate, and then the first bevel cutting component, the second bevel cutting component, the first straight cutting component and the second straight cutting component work in conjunction, so the outer edge contour of the stamped flower shaped plate can be quickly and accurately punched and shaped, reducing the subsequent cutting and correction steps and simplifying the manufacturing process. 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 shaped plate is accurately formed, improve production efficiency, and solve the technical problem of the difficulty of correcting the contour of the stamped flower shaped plate.

[0016] 4. The present invention enables the first straight cutting component and the second straight cutting component to follow the punching action of the first bevel cutting component in linkage, and utilizes the transmission method of gear racks to achieve precise coordination between the components, reduce the use of separate driving devices, reduce equipment costs and energy consumption, and at the same time ensure the synchronization and accuracy of the punching action, thereby achieving all-round synchronous punching and shaping of the outer contour of the flower modeling plate, and significantly improving processing accuracy and efficiency.

[0017] 5. The present invention designs a waste baffle, a guide plate and a shaking assembly. 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 multiple eccentric wheels connected coaxially to rotate. The multiple eccentric wheels perform eccentric rotational motion, generating intermittent thrust on the bottom of the waste baffle, causing the waste baffle to swing. The waste baffle can shake off the waste that may remain on its surface to keep the surface of the waste baffle clean, and during the swinging process of the waste baffle, it drives the slapping rod to clap the top of the guide plate, causing the guide plate to vibrate, shaking off the waste that may remain on the surface of the guide plate to keep the surface of the guide plate clean. Through the cooperation of the shaking assembly with the waste baffle and the guide plate, the waste generated in the punching process and remaining on the surfaces of the waste baffle and the guide plate can be effectively shaken off, preventing waste accumulation from affecting subsequent punching work, while also reducing the workload of manual waste cleaning and improving production efficiency.
