Abstract

The invention discloses a bicycle elbow device comprising a bottom plate, an elbow mold, a pneumatic cylinder, a first hydraulic cylinder, a second hydraulic cylinder and a bicycle head fixed seat, wherein the elbow mold is fixed on the bottom plate, the first hydraulic cylinder and the bicycle head fixed seat are fixed on the bottom plate at the right side of the elbow mold, the pneumatic cylinder and the hydraulic cylinder are fixed on the bottom plate at the left side of the elbow mold, a positioning block adaptive to the head of the elbow is arranged on the pneumatic cylinder, a compression block adaptive to the surface of the elbow is arranged on the first hydraulic cylinder, and a buckling device is arranged on the second hydraulic cylinder. The bicycle elbow device has the advantages of being capable of setting holding-up time according to performances of a straight pipe, and further keeping no bouncing of the bent elbow, and ensuring the product quality.

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, ...
