Problems solved by technology

Curved surfaces with different shapes require different molds, so the processing cycle is long, requiring a lot of manpower and material resources, and the degree of automation is low, which cannot meet the needs of small batch modern production
At the same time, the manual forming method has poor processing quality, high labor intensity and low production efficiency

Embodiment Construction

[0023] The specific content and working process of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings, but the arrangement of the working rolls is not limited to the arrangement in the accompanying drawings.

[0024] Referring to the embodiment of Fig. 1, according to the required three-dimensional shape of the plate, the adjustment rod 7 of the adjustment mechanism 2 is adjusted by manual control or numerical control system to make the open bearing 6 pull or press the flexible work roll to make it bend and deform; at one end of the flexible work roll Or both ends can be provided with expanders, so that it can freely expand and contract during shape adjustment, and can be fixed after shape adjustment to prevent relative displacement in the axial and circumferential directions. At the same time, in order to make the deformation of the flexible work rolls easier, the lower frame of the equipment can move al...

Abstract

The present invention relates to a equipment for flexible formation, in particular, it relates to a three-dimensional curved surface forming equipment capable of using flexible roll. Said equipment consists of working roll, machine frame, working roll regulation mechanism and workpiece holding and rotating mechanism. Said equipment has at least two working rolls, at least one of them can be bent and can be regulated. Besides, said invention also provides the working principle of said three-dimensional curved surface flexible forming equipment and its concrete operation method.

Description

technical field [0001] The invention relates to equipment for plastic forming, in particular to a three-dimensional curved surface flexible forming device, which belongs to the field of mechanical engineering. Background technique [0002] The current plate rolling device can only form workpieces whose generatrix is ​​straight, such as cylinders, cones, etc.; while the forming of three-dimensional curved parts is mainly realized through mold processing or manual methods. Curved surfaces with different shapes require different molds, so the processing cycle is long, requiring a lot of manpower and material resources, and the degree of automation is low, which cannot meet the needs of small batch modern production. At the same time, the manual forming method has poor processing quality, high labor intensity and low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a three-dimensional curved surface flexible forming d...
