Abstract

The invention discloses a complex component three-dimensional free bending forming method based on a multi-legged parallel robot. The method is characterized in that an adopted bending die moving device comprises a fixed platform, end executors and multiple driving rods, wherein the multiple driving rods are arranged between the end executors and the fixed platform and used for controlling movement of the end executors in space; a bending die moving platform is directly driven by a six-degree-of-freedom parallel mechanism or is driven in a serial-parallel mixed driving mode. The advantages of large rigidity weight ratio, high bearing capacity, small error accumulation, good dynamic performance, compact structure, low overall manufacturing cost and the like of the parallel mechanism are given full play to. The forming precision of three-dimensional free bending is improved. The problem that large-size thick-walled pipe fittings are hard to form through three-dimensional free bending is solved.

Description

technical field The invention belongs to the technical field of advanced manufacturing of metal complex components, in particular to a three-dimensional free bending forming method of complex components based on a multi-legged parallel robot. Background technique Metal complex components with various cross-sectional shapes are widely used in many fields such as aerospace, nuclear power, automobiles, ships, petrochemicals, construction and other civil industries, and play an important role in reducing the production cost and weight of products. Large-size thick-walled tubes have high strength and good pressure and bending resistance. They are mainly used as petroleum geological drilling tubes, cracking tubes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural tubes for automobiles, tractors, and aviation. The three-dimensional free bending method of complex components can realize high-precision moldless forming of pipes, profiles, and wires under va...
