Abstract

The invention discloses a progressive forming processing platform with a displacement compensating function and a control method. The progressive forming processing platform is a multi-freedom parallel mechanism which consists of slide rails, a slide table, a shoulder-shaped tenon, motion chain large arms, shoulder fork frames, fork frame tensons, arm fork frames, motion chain small arms, a disc fork frame, a telescopic pole, a movable flat plate, and the like; a gear shaft, a lifting tool holder, a tool bit handle sleeve, a spring chuck, a pressure sensor, and the like define a tool bit module which integrates forming force and displacement compensation; and a hydraulic cylinder, an upper pressure plate, a lower pressure plate and related accessories define a movable clamp. The progressive forming processing platform solves the problem that feeding motion track precision of a forming tool bit controlled by a conventional numerical-control series motion mechanism is insufficient. The progressive forming processing platform is simple in structure, is small in size, is convenient in mounting, is suitable for progressive forming processing of high-precision parts and single small-batch boards, and can meet various individual needs.

Description

technical field [0001] The patent of the invention belongs to the field of sheet metal processing, and relates to a multi-degree-of-freedom parallel motion mechanism and a displacement compensation tool head, in particular to a progressive forming processing platform and control method for sheet metal with high precision and complex shapes. Background technique [0002] Sheet metal forming has been widely used in the manufacturing industry in recent years. As a new type of sheet metal forming technology, incremental forming technology is a dieless rapid prototyping technology. The height direction is discretized into a series of two-dimensional shapes, and the feeding of the forming tool head along the vertical direction and along the horizontal direction is controlled by the numerical control system to realize the plastic forming of the sheet metal layer by layer. However, the inventors found that the current incremental forming processing platform relies on a series kinema...
