Flexible quickly forming processing method for straight wall and turning device for supporting mould thereof

Abstract

The invention provides a flexible quickly forming processing method and a supporting device thereof and particularly provides a flexible quickly forming processing method for a straight wall and a turning device for a supporting mould thereof. The turning device for the supporting mould comprises an upper top plate and a lower top plate, wherein the upper top plate and the lower top plate are connected to each other through a bearing and a shaft and can be turned mutually. The turning device further comprises a cushion block between the upper top plate and the lower top plate. According to the processing method for the straight wall, two different cushion blocks are used and a straight wall structure can be processed through only twice conventional forming processing; a forming angle theta can be adjusted after the turning device is mounted between an X-Y operating platform and the supporting mould; and the forming angle theta is prevented from being 0 degree during a process of forming the straight wall structure, thereby extremely reducing a thinning phenomenon and preventing a metal plate from cracking.

Description

technical field [0001] The invention relates to a rapid prototyping processing method and a device thereof, in particular to a processing method of a straight wall structure in the numerical control flexible rapid prototyping of metal plates and a supporting model turning device thereof. Background technique [0002] The existing CNC flexible rapid prototyping processing method for sheet metal is to directly place the support model on the X-Y workbench of the CNC flexible rapid prototyping lathe, and the metal sheet as the processing raw material is kept on a plane parallel to the workbench by a clamping mechanism, and the forming head Along the Z direction of the supporting model, the local plastic processing is performed on the plate layer by layer to form a workpiece with the same shape as the supporting model. But prior art has following problem: [0003] First, the thickness reduction of the sheet is relatively large. Such as figure 1 As shown, if the initial thickne...

Problems solved by technology

[0004] Second, straight wall forming is more difficult, and one-time forming cannot be realized

In the case that there is a right angle part in the workpiece, it is difficult to form it. The minimum forming angle θ of aluminum is 15°, the minimum forming angle θ of SPC is 20°, and the minimum forming angle θ of SUS is 25°. It can be seen that The shape of the workpiece is significantly limited

For the straight wall structure, it must be realized through multi-pass forming, and one-time forming will inevitably lead to the cracking of the plate
