Continuous bending and forming device of ring

Abstract

The invention provides a continuous bending and forming device of a ring. The continuous bending and forming device comprises a feeding mechanism, and a shaping mechanism, an annealing mechanism, a cutting mechanism and a roll forming mechanism which are sequentially arranged in the feeding direction, wherein the feeding mechanism is used for conveying strip-shaped raw materials; the shaping mechanism is used for continuously processing sections of the continuously passing strip-shaped raw materials into objects with shapes and sizes required by finished products; the annealing mechanism is used for continuously annealing the strip-shaped raw materials to a proper state for roll forming processing; the cutting mechanism is used for cutting the strip-shaped raw materials according to required angles; the roll forming mechanism is used for performing roll forming on the strip-shaped raw materials to form the ring finished products; the roll forming mechanism is provided with an ejection mechanism; and the ejection mechanism is used for sending the end parts of the strip-shaped raw materials into a roll forming space of the roll forming mechanism. According to the continuous bending and forming device, the problem that other methods are low in processing precision, low in processing efficiency and high in material waste rate under general conditions is solved.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a processing equipment for ring parts, which is especially suitable for continuous bending forming processing of lock rings for blind rivets. Background technique [0002] The mechanical locking bulge type blind rivet is a high-end single-sided mounting fastener used in aerospace and other fields. An important part of the locking mechanism is the lock ring. During the riveting process, it will undergo plastic deformation and the riveting is completed. Finally, it can play an important role in locking the core rod and preventing it from loosening. Such as figure 1 The shape of the part shown is a thin-walled ring structure with a chute 15 . The current processing technology of this kind of parts is milling or wire cutting of round bars after several lathes. The material removal process of several lathes has caused a great waste of raw materials. During the processi...
