[0003] At present, the 4-hole connection purlin support plate is punched or punched by CNC flat drilling machine or punching machine. The production of 4-hole connection purlin support plate requires multiple rotation and positioning of the drilling equipment or purlin support plate until the hole production requirements are met before punching. This single hole making is not only time-consuming and inefficient, but also unable to achieve mass production in a short time to ensure the progress of the project; and after multiple rotations of the drilling equipment or the positioning of the purlin support plate, the hole spacing will be inconsistent, thus affecting the hole quality of the mass-produced purlin support plate, affecting the installation quality and construction efficiency of the steel structure workshop. Summary of the invention
