Description

Technical Field

[0001] The utility model relates to the technical field of wheelchair pipe fittings processing, in particular to an integrated punching device for wheelchair straight pipe fittings. Background Art

[0002] During the manufacturing process of a wheelchair, the wheelchair frame is generally constructed of metal pipes, including straight pipe fittings. Before constructing the wheelchair frame, it is necessary to perform hole punching on the straight pipe according to the processing requirements. However, there are currently two problems when punching straight pipes:

[0003] Since the straight pipe fittings are tubular hollow structures, there is no support on both sides of the hole when punching, so it is easy to cause bending around the hole during punching, resulting in irregular hole positions and inconvenience for subsequent installation;

[0004] like Figure 5 As shown, when punching from top to bottom, the metal sheet remaining on the inner wall of the upper hole enters the inner cavity of the straight tube, while the metal sheet remaining on the lower hole wall bends downward, and the remaining metal sheet is exposed, which poses a risk of scratches, requiring subsequent grinding processing, and cannot be fully processed in one go.
