Abstract

The invention discloses a manufacturing process and structure of a pipe manufactured integrated horn sleeve front fork vertical pipe. The process comprises the following steps of A, performing blanking; B, performing heading; C, performing pipe drawing; D, performing two-end trimming for the first time; E, performing pipe expanding for the first time; F, performing pipe expanding for the second time; G, performing one-end trimming; H, performing conical forming; I, performing two-end trimming for the second time; J, performing horn mouth edge-trimming and trimming; and K, performing welding. The manufacturing process has the beneficial effects that the problem of false welding between a sleeve and the bottom of the vertical tube is solved, and the potential safety hazard that falling off is prone to occurrence during riding is avoided.

Description

technical field [0001] The invention relates to the technical field of bicycle front fork tubes, and more specifically, the invention relates to a manufacturing process and structure of a front fork riser tube with integrated control horn sleeve. Background technique [0002] People are very familiar with bicycles, and every process in the field of bicycle manufacturing is very delicate, because the quality of each component directly affects the use effect of consumers, and there will be safety hazards in the use of bad products , And lead to some series of dangerous accidents. [0003] Especially the front fork riser part and the handle part of the bicycle are the most important. The sleeve pipe of the existing self-propelled front fork riser and the bottom of the standpipe are prone to false welding, which causes people to fall off easily when riding a bicycle. The potential safety hazards, such as the sudden rupture of some parts of the bicycle front fork riser, will lea...
