In order to improve the production efficiency and quality of steel structures, as well as promote the intelligent development of the steel structure industry, CNC drilling machines are becoming more and more popular in the steel structure processing industry, and their applications are becoming more and more extensive.The following describes the main applications of CNC drilling machines in the production of steel structures：
| Plate drilling and processing | 1.Connection hole processing | In steel structures, many components need to be bolted together.For example, for the connecting part of the steel column and the steel beam, CNC drilling can accurately drill holes in the steel plate for installing bolts.It can be processed according to pre-set hole spacing, aperture size and arrangement.Generally, the accuracy requirements of these connecting holes are higher, because inaccurate hole positions may cause the bolts to fail to be installed smoothly, or when the steel structure is under load, the connection parts will be loose and other safety hazards.The positioning accuracy of CNC drilling machines can reach ±0.1mm or even higher, which can well meet the requirements of this high precision.
For some large steel structures, such as bridges and high-rise buildings, a large number of high-strength bolted connections are used.CNC drilling can drill high-quality bolt holes on thick steel plates (up to tens of millimeters in thickness) to ensure the reliability of the connection.For example, at the splicing of the steel beams of the bridge, the bolt holes drilled by CNC drilling can ensure that the steel beams are closely connected, so that the bridge structure can withstand various loads such as vehicles. |
| 2.Mounting hole machining | Steel structure components also need to install some ancillary equipment or components, such as the installation of lighting panels and ventilation equipment on the roof frame of the steel structure of the plant.CNC drilling can drill mounting holes in the relevant positions of the roof frame, and its processing speed is fast, which can improve the efficiency of the entire steel structure production.At the same time, since it can be programmed in advance according to the installation size of the equipment, the accuracy of the hole position drilled can ensure the accurate installation of these ancillary equipment and reduce the adjustment time of on-site construction. | |
| Drilling and processing of shaped steel | 1.H-steel processing | H-steel is a profile commonly used in steel structures.CNC drilling can drill holes on the flanks and webs of H-steel.For example, when making crane beams for industrial plants, holes need to be drilled into the web of H-shaped steel to install crane rails.Through precise positioning and control, CNC drilling can drill holes that meet the requirements on H-steels of different specifications (such as different heights, flange widths and web thicknesses).It can realize the equal-spacing or non-equal-spacing arrangement of multiple holes according to the design requirements, and can be processed on the surface of complex-shaped steel to ensure the quality and accuracy of the holes. |
| 2.Channel steel and angle steel processing | Channel steel and angle steel are also commonly used in steel structures to make various brackets, frames, etc.CNC drills can drill holes on their surfaces for connecting other components or installing equipment.For example, angle steel brackets on the exterior walls of buildings are used to fix billboards and other facilities. CNC drills can drill suitable holes in the angle steel so that the billboards can be bolted to the brackets.Moreover, for some connection parts with special angle requirements, CNC drilling can accurately drill holes on the bevel of channel steel and angle steel to meet the diverse connection needs of steel structures. | |
| Drilling of complex shape components | 1.Processing of curved and special-shaped | In some steel structures with artistic shapes, there will be many curved or special-shaped components.For example, in the dome structure of a stadium, some components may be curved steel plates or steel combinations.CNC drilling can accurately drill holes on the surface of these components through computer-assisted programming according to the shape characteristics of these components.It can adapt to changes in the curvature of the component, ensure that the holes drilled are perpendicular to the surface of the component or drilled at a specific angle, and provide convenience for subsequent assembly and connection.This kind of precise drilling on complex-shaped components is very critical to ensure the stability of the entire steel structure and the accuracy of modeling. |
| 2.Node board processing | The node plate is a key component in the connection of steel structures, and its shape and hole position distribution are often more complex.CNC drilling can accurately process each connecting hole according to the design drawings of the node board.For example, on the node board of the space grid structure, it needs to be connected to multiple rods. CNC drilling can drill holes in different directions and different spacing on the node board to ensure that each rod can be accurately connected to the node board by bolts or welding, so as to effectively transmit the internal force of the structure and ensure the safety and reliability of the entire grid structure. |
