Description

technical field

[0001] The invention relates to a bicycle pipe bending device. Background technique

[0002] The existing bicycle pipe bends are all made by placing the straight pipe on a punching machine and punching it into a pipe bend. However, because the punching machine presses down and lifts up quickly, it cannot maintain the pressure, resulting in a large rebound of the pipe after bending. The quality of the pipe produced is poor and unstable. Contents of the invention

[0003] The object of the present invention is to provide a bicycle pipe bending device, which can effectively solve the problem that the existing pipe bending process cannot maintain pressure, resulting in easy rebound and poor quality of the bent pipe.

[0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical proposals: a bicycle pipe bending device, comprising a base plate, a pipe pipe bending mold, a pneumatic cylinder, ...
