Description

Technical Field

[0001] The invention relates to the technical field of profile processing equipment, in particular to a greenhouse shaped steel punching machine. Background Art

[0002] See also Figure 1 It is a schematic diagram of the cross-sectional structure of the "J" steel used to construct the greenhouse frame. It consists of the middle arc-shaped back plate 01, the side plates 02 on both sides of the arc-shaped back plate 01, and the arc-shaped wing plates 03 on the outside of the side plates. The "J" steel can be processed and formed by steel plates. It has abundant material sources and low manufacturing costs. It also has the advantages of high support strength and convenient design and installation of greenhouse frames. Therefore, the "J" steel is generally used to build greenhouse frames. In order to achieve combined installation, it is necessary to process symmetrical installation holes 04 on the two side plates 02 at the design position of the "J" steel. At present, the installation holes 04 on the "J" steel are mostly processed by manual drilling with an electric drill, which has high labor intensity, low work efficiency, inaccurate drilling angles and positions, and affects the later installation.
