Abstract

The invention discloses an ultrasonic-assisted vibration multi-point mold support rotary forming device and belongs to the technical field of metal profile bending forming technology. The device is mainly composed of a work table, a profile, a profile clamp, a pressure roller hydraulic transmission and force application device, a pressure roller, a guard plate, a core mold, a hinge device, a sleeve, a core mold hydraulic transmission device, a spring, an amplitude-change pole, a transducer, an ultrasonic wave generation device, an elastic pad, a mold-free multi-point mold, a spring damper anda mold base. The forming shape of the mold-free multi-point mold can be adjusted according to practical machining requirements, and the frequency and amplitude of the ultrasonic wave generator can beadjusted according to the materials and machining size of the practically-machined profile so as to achieve the purpose of assisted forming. A bending forming device and the ultrasonic-assisted vibration multi-point support mold technology are combined together, a traditional profile bending forming device is improved, the profile forming stability is improved, the forming range is expanded, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of bending forming of metal profiles, and in particular relates to ultrasonic-assisted plastic forming and moldless multi-point forming methods. Background technique [0002] With the development of automobile lightweight technology, high-strength steel for automobile anti-collision beams has been widely promoted and applied. Automobile manufacturers require that the strength and hardness of the anti-collision beams produced reach a certain level, and at the same time, they also require to minimize the defects of the anti-collision beam profiles to improve the stability of the formed parts. This has brought severe challenges to anti-collision beam manufacturers, and also brought great challenges to metal profile bending processing devices and processing methods. [0003] The traditional bending forming device is to further bend the formed profiles, such as rectangular profiles, circular profiles, etc., to d...
