Abstract

The invention discloses a multi-step continuous bending device of arc-shaped components. The multi-step continuous bending device comprises a base. A round die pressing assembly is slidingly arrangedon the base in the Y direction, semi-ring setting assemblies are arranged on the portions, on the two sides of the round die pressing assembly, of the base in the X direction correspondingly, startingend positioning blocks are arranged on the sides, close to the round die pressing assembly, of the semi-ring positioning assemblies in the X direction, and a passageway allowing the components to penetrate is formed between the semi-ring setting assemblies and the starting end positioning blocks in the X direction. A three-fourth-ring die pressing assembly is slidingly arranged on the other sideof the round die pressing assembly in the X direction. The multi-step continuous bending device has the beneficial effects that the component bending procedures are simple and convenient to implement,the device is suitable for forming the components of different specifications, and the bending modules are simple in structure and compatible with multi-shape forming of the 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,...
