The punching machine can perform thin-sheet processing, stamping, molding, embossing and other operations that force metal into the die. It generally includes a power mechanism, a tug assembly, a lower die assembly, a punching assembly, and matching brackets, fixing mechanisms, etc.

[0003] There are a lot of supporting frames in various construction projects. I-beams are widely used in the erection of supporting frames due to their high strength and non-deformation. Multiple I-beams need to be connected with fixings. Therefore, an I-beam web punching machine is needed to drill holes in the I-beam web. The lower die assembly of some existing I-beam web punching machines only plays a supporting and fixing role in the drilling process of I-beam materials. For arc-shaped I-beams that need continuous drilling, the drilling distance can only be manually calculated and the I-beam can be moved. The moving process is time-consuming and labor-intensive, and there are large errors. Therefore, in view of the above problems, a lower die assembly of an I-beam web punching machine is proposed.
