Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to a U-shaped tube multi-angle punching integrated machine. Background Art

[0002] In daily life, U-shaped tubes are often used as support members for products such as tables and chairs. The fixation between the U-shaped tube and other parts of the product is mostly achieved through screws. Therefore, the U-shaped tube needs to be drilled during the production process for installing screws. The U-shaped tube consists of a horizontal tube and two vertical tubes located on both sides of the horizontal tube, and drilling operations need to be performed on all three parts. Most traditional drilling devices have a single drill bit, and when drilling multiple holes, separate drilling operations for each part need to be carried out sequentially. A hydraulic punching machine for U-shaped tubes disclosed in a Chinese patent with the publication number "CN108067541A" can punch the two vertical tubes of the U-shaped tube simultaneously compared with the traditional operation of drilling holes one by one, but it cannot perform the punching operation on the horizontal tube. As the horizontal tube is the connection and fixation part in contact with the product such as the tabletop, it needs to be drilled and fixed to the tabletop through screws, and workers need an additional drilling machine for processing the horizontal tube. Therefore, the punching machine in the above patent is still not perfect. Summary of the Invention
