Abstract
The invention discloses a negative pressure adsorption type rolling forming tool, device and method for incremental forming, solving the problems of friction resistance between a forming tool and plate processing and limited application range of a large tilt angle realization device in the prior art. The negative pressure adsorption type rolling forming tool, device and method has the beneficial effects of convenience in operation and effective lubrication for a plate in the processing process. According to the scheme, the negative pressure adsorption type rolling forming tool comprises a ballseat with a set length and forming balls, wherein the ball seat is hollow, and the inner part of the ball seat is used for storing lubricating oil temporarily; part of the forming balls can be nestedto the end part of the ball seat, and gaps are formed between the forming balls and the ball seat; the forming balls are driven by the ball seat to form a workpiece to be processed; and the lubricating oil lubricates the workpiece to be processed through the gaps between the forming balls and the ball seat.
Description
Technical field [0001] The present invention relates to the technical field of progressive forming, in particular to a negative pressure suction type rolling forming tool, device and method for progressive forming. Background technique [0002] The sheet metal progressive forming process is to decompose the complex three-dimensional model according to a series of contour lines, and the computer-controlled forming tool is processed layer by layer on the two-dimensional plane. In principle, incremental forming can process arbitrarily complex workpieces and does not require molds. It has huge advantages for manufacturing small batches and personalized new products. Compared with the stamping process, the progressive forming process is a local plastic deformation, which makes full use of the deformability of the sheet material, so it can form complex shapes that cannot be formed by the traditional stamping process, and has a wide range of application potential in various fields.
