Detailed implementation mode
[0024] The following further details the present utility model through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present utility model cannot be limited thereby.
[0025] A four-head needle-punching marking device for rectangular steel pipes includes a controller. The innovation lies in that it further includes a needle-punching marking assembly, a bracket 6, a control handle 8, positioners 10 and 16. The needle-punching marking assembly is fixedly installed below the bracket, the control handle is fixedly installed on the top surface of the needle-punching marking machine, the positioners are symmetrically and fixedly installed at both ends of the needle-punching marking assembly, and the controller is connected to the needle-punching marking machine set for control.
[0026] The needle-punching marking assembly is divided into four groups, namely the first needle-punching marking machine set, the second needle-punching marking machine set, the third needle-punching marking machine set, and the fourth needle-punching marking machine set. The first needle-punching marking machine set, the second needle-punching marking machine set, the third needle-punching marking machine set, and the fourth needle-punching marking machine set have the same structure and are respectively composed of a first marking machine 1, a first air valve 2, a first electromagnet group 15, a second marking machine 3, a second air valve 14, a second electromagnet group 13, a third marking machine 4, a third air valve 5, a third electromagnet group 12, a fourth marking machine 7, a fourth air valve 11, and a fourth electromagnet group 9.
