Abstract

The invention discloses a multi-step continuous bending device for an arc-shaped member, which comprises a base on which a circular die assembly is slid along the Y direction, and the base is located at the center of the circular die assembly. Both sides are respectively provided with a half-ring shaping assembly along the X direction, and the side of the half-ring shaping assembly close to the circular die assembly is provided with a starting positioning block along the X direction, and the half-ring shaping assembly and the starting positioning block There is a channel for components to pass through along the X direction; the other side of the circular die assembly is slidingly provided with a three-quarter ring die assembly along the X direction; the present invention has the advantages of simple component bending process Convenience, adaptability to the forming of components of different specifications, simple structure of the bending module, and the beneficial effects of being compatible with the forming of multiple shapes of components.

Description

technical field [0001] The invention belongs to the technical field of component forming, in particular to a multi-step continuous bending device for arc-shaped components. Background technique [0002] With the continuous mature application of plastic processing technology, bars, pipes, square steel and profiles of various cross-sectional shapes (such as T, L, ∏, □) are widely used in production and processing. The shapes of parts are also different, but the most basic There are two cases of straight lines and arcs. Through the combination of different numbers of straight lines and arcs, various arc components can be formed. These components are in great demand in daily life and industrial production. The most common arc components are shown in figure 1 Among them, the half ring, the whole ring, the ring and the cane are the most typical representatives. [0003] These components are generally formed by bending, and each component requires one or more sets of special dies,...
