Sheet material mold-free multi-point forming device based on viscous medium transfer force and method

Abstract

The invention relates to a sheet multipoint molding device and relative method, based on adhesive medium force transmission. Wherein, the lower die cavity is formed by concave mould and the bottom plate of concave mould; the bottom of concave mould has the discharge hole of adhesive medium, which is connected to the cylinder via the channel inside the bottom plate; the fixing compress device is formed by the upper mould, motor, mounting element, convex mounting plate and the punch head connected to the flexible sheath; the flanging ring, convex mould fixing plate, flexible sheath and the punch head form the upper die chamber; the sheet compress device is formed by the upper edge of concave mould and the flanging ring. The invention uses adhesive medium with uniform force transmission, to reduce the producing period, the producing cost, avoid the surface crack caused by rigid mould, while the thickness is uniform.

Description

technical field [0001] The invention belongs to sheet material forming technology, in particular to a soft mold or moldless flexible forming method for sheet material, in particular to a device and method for sheet material non-die multi-point forming based on viscous medium force transmission. Background technique [0002] Sheet metal forming technology is widely used in national economic sectors such as automobiles, electrical appliances, ships, aerospace, weapons, etc. With the rapid development of computer technology and the change of the earth's environment, the traditional manufacturing technology is challenged, how to process products that meet market demand at low cost, quickly and with high quality determines the success or failure in the international economic competition. For this reason, in the field of plate processing, the flexible processing technology that adapts to market changes and the intelligent processing technology that controls the stamping process in...

Problems solved by technology

It uses a hard mold to transmit force, it is difficult to exert the maximum forming limit of the material, there are problems that cracks are easily generated on the surface, and the surface quality of the workpiece cannot be guaranteed

Chinese patent 00115996.8 "Numerical Control Dieless Forming Machine for Plates" discloses a device consisting of a frame-type body, a working platform, a plate clamping support mechanism, and a double screw drive transmission system. It is a milling or cutting forming technology. It cannot deform the plate

The use of elastic pads can suppress the occurrence of defects to a certain extent, but it cannot be eliminated
