Abstract
The invention discloses a rolling forming tool and a device for gradual forming, and a method. The rolling forming tool for the gradual forming solves the problems that machining frictional resistancebetween a forming tool and boards is large, and the application scope of the device is limited due to a relatively large inclination angle in the prior art, and has the beneficial effects that the operation is convenient, and the boards are effectively lubricated in the machining process. According to the scheme, the rolling forming tool for the gradual forming comprises a ball seat with the setting length, and a forming ball; the ball seat is hollowly arranged; the interior of the ball seat is used for storing lubricating oil temporarily; a part of the forming ball can be nested at the end of the ball seat; a gap can be formed between the forming ball and the ball seat; the forming ball is driven by the ball seat to form a to-be-machined workpiece; and the lubricating oil lubricates theto-be-machined workpiece through the gap between the forming ball and the ball seat.
Description
technical field [0001] The invention relates to the technical field of progressive forming, in particular to a rolling forming tool, device and method for progressive forming. Background technique [0002] The progressive forming process of sheet metal is to decompose the complex three-dimensional model according to a series of contour lines, and the computer-controlled forming tools are processed layer by layer on the two-dimensional plane. In principle, this method can process workpieces of arbitrary complexity and does not require molds. It has great advantages for manufacturing small batches and personalized new products. Compared with the stamping process, the incremental forming process is a local plastic deformation, which makes full use of the deformation ability of the plate, so it can form complex shapes that cannot be formed by the traditional stamping process, and has a wide range of application potentials in various fields. Friction is ubiquitous in production...
