Embodiment Construction

[0024] 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 setting of the working rolls is not limited to the quantity and arrangement in the accompanying drawings.

[0025] refer to figure 1 , 2 In the embodiment, two bendable work rolls 2 exert pressure on the workpiece from both inside and outside sides of the cylindrical workpiece 1; according to the shape of the required workpiece, the shape of the bendable roll 2 can be adjusted by the adjustment mechanism 3; the drive of the bendable roll 2. The cylindrical workpiece 1 can be rotated together, and the workpiece 1 can be deformed three-dimensionally.

[0026] Referring to the embodiment of Figures 3 and 4, two bendable work rolls 2 are arranged at 180 degrees; according to the shape of the required workpiece, the shape of the bendable roll 2 can be adjusted through the adjustment mechanism 3, and...

Abstract

The present invention relates to plastic forming apparatus, and is especially flexible forming apparatus with flexible roll for machining 3D workpiece. The flexible forming apparatus consists of work rolls, regulating mechanism, frame and work roll driving mechanism. Each of the adjustable flexible work rolls has several regulating mechanisms for curvature degree regulation. The adjustable flexible work rolls are arranged inside or outside the workpiece. The work rolls rotating while producing centrifugal or centripetal motion make the workpiece diameter decreased or increased. The frame is a double supported one or a cantilever one. The present invention can form 3D workpiece, and has high production efficiency and low production cost.

Description

technical field [0001] A flexible forming device for processing a three-dimensional workpiece by using a bendable roller is a device used for plastic forming of the workpiece and belongs to the field of mechanical processing. Background technique [0002] At present, the processing of cylindrical or rod-shaped three-dimensional workpieces is mainly through traditional processes such as spinning, roll forging, and cross wedge rolling, which not only cost high, but also take a long time. Therefore, it is necessary to provide a device to solve the processing of the workpiece and greatly improve the production efficiency and the like. Contents of the invention [0003] The object of the present invention is to change the traditional processing method of cylindrical or rod-shaped three-dimensional workpieces, and provide a flexible forming device for processing cylindrical or rod-shaped three-dimensional workpieces using bendable rollers. [0004] Above-mentioned purpose of th...
