Elbow forming equipment for automobile skylight guide rail

Abstract

The invention relates to the technical field of automobile accessory manufacturing, and provides elbow forming equipment for an automobile skylight guide rail. A base, a profiling die mounted on the base, a rotating frame rotationally erected on the base, a pressing die mounted on the rotating frame, and a die core mounted on the pressing die are included. The profiling die, the die core and the pressing die define a die cavity for an elbow of the automobile skylight guide rail to be inserted, and the die core is used for being inserted into and filling a cavity of the elbow. The profiling dieis provided with a curved surface wall, the central axis of the curved surface wall is coaxial with a rotating shaft of the rotating frame, the rotating frame can drive the pressing die and the die core to rotate, and the pressing die and the die core are used for clamping the elbow to rotate with the rotating shaft as the circle center and along the curved surface wall. According to the elbow forming equipment for the automobile skylight guide rail, bending forming of the elbow is achieved through the spinning forming principle, the die core is inserted into and fills the cavity of the elbow, the elbow forming efficiency is high, the consistency of the formed elbow is high, meanwhile, the structure is simple, and the cost is low.

Description

technical field [0001] The application belongs to the technical field of auto parts manufacturing, and more specifically relates to an elbow forming equipment for an auto sunroof guide rail. Background technique [0002] Car sunroof rails are generally formed with elbows for application requirements. At present, the elbow forming for the car sunroof guide rail is generally formed by stamping or by a special bending machine. Since the guide rail of the automobile sunroof is made of aluminum alloy and has a cavity, when the elbow is formed by stamping, rubber strips need to be inserted into the cavity of the elbow, which requires many forming processes and low efficiency; Elbow deformation is large, there are defects such as outer edge cracks, inner circle wrinkles, cavity deformation and surface damage, which eventually lead to unsmooth elbow forming. However, if the special bending machine is used for processing, the bending machine not only has high cost and large initial...
