The method can solve the problem of uneven deformation of the plate material in the common incremental forming process, thereby improving the forming performance of the plate material.

Description

Multidirectional hammering type progressive forming method and product obtained by same
Technical Field

Background
The plate incremental forming technology adopts the idea of 'layered manufacturing' of rapid prototyping manufacturing technology, is driven by a CAD model, can form a product without a die or only a male die, is very suitable for processing single-piece or small-batch thin shell products, and is a beneficial supplement to the traditional stamping forming. Has wide application prospect in the manufacturing industries of aviation, aerospace, household electrical appliances, medical appliances, automobiles and the like.
So-called progressive forming, in which the tool and the sheet are always in contact during the forming process, is also called continuous contact progressive forming. If the tool moves along the processing track and performs hammering action during the forming process, namely the tool is continuously lifted and dropped to periodically contact the sheet, the hammering type incremental forming is called. The relative continuous contact progressive forming is realized, and the hammering progressive forming has small friction and almost zero between the plates along the movement horizontal direction due to the periodic contact with the plates, so that the forming performance of the plates is further improved, the deformation force is reduced, the distortion of the finished piece along the processing direction can not occur, and the finished piece of the mesh plate can be formed.
The prototype of incremental sheet forming is that the craftsman uses a hammering method to deform the sheet to the shape to be formed. When the worker hammers the workpiece, the hammering direction can rotate freely, and the local deformation of the sheet is controlled by continuously adjusting the hammering direction and the hammering force in the hammering forming process, so that the local thickness of the workpiece can be controlled. In contrast, in the conventional hammering type incremental forming, since the hammering angle is fixed to 90 °, the hammering direction is not changed during forming, and the plate thickness cannot be freely adjusted.
