Straightening mechanism and shape correcting method for cold-drawn oil cylinder pipe

The invention discloses a straightening mechanism and a shape righting method for a cold-drawn oil cylinder pipe, and belongs to the technical field of oil cylinder pipe machining shape righting. The straightening mechanism for the cold-drawn oil cylinder pipe comprises a sliding adjusting structure, and the top of the sliding adjusting structure is slidably connected with a sliding supporting structure; an oil cylinder pipe pushing mechanism used for feeding of oil cylinder pipes to be machined is installed at the rear end of the top of the sliding supporting structure, and a core rod feeding mechanism used for pushing of shape righting core rods is installed at the front end of the top of the sliding supporting structure. And a roll shaft shape correcting structure is arranged on one side of the sliding adjusting structure. By designing the oil cylinder pipe propelling mechanism, the core rod feeding mechanism, the shape righting core rod and the roll shaft shape righting structure, rapid shape righting of
