Folding system for a cutting blade

Abstract

The present invention provides an unified folding system for processing in one work line all working processes needed in cutting and folding a cutting blade in a shape suitable to a sheet matter molding. A cutting blade supplied from a transferring unit of the cutting blade is cut in a length suitable to a sheet matter molding configuration in a cutting molding unit adjacent thereto, simultaneously the cutting tip used in cutting is transferred together with the cutting blade to a folding device side through a guide member set which is to be contacted with the cutting molding unit, the cutting blade transferred to the folding device is folded in a predetermined shape by a folding member which performs a going-straight movement and a rotating movement, and thereby, at this time, the cutting tip is detached outside by a tare. Accordingly, a working efficiency and a productivity in the cutting and folding of the cutting blade are improved and increased.

What is claimed is:  
     
         1 . A system for folding a cutting blade, which is used for sheet material molding, in a shape conforming to a desired sheet material molding configuration, the system comprising: 
 a transferring unit for transferring the cutting blade;    cutting means, situated between said transferring unit and a guide nozzle, for cutting the cutting blade, which is supplied from said transferring unit, in a length substantially corresponding to the sheet material molding configuration, wherein a cutting tip is preserved on the cutting blade;    a guide member of a hollow shape, interposed said cutting means and a folding means and configured to connect said cutting means and the folding means, said guide member having a passage for guiding the cutting blade through the cutting means to the folding means;    folding means, supported such that it may be revolved and moved in a straight line direction for applying a force against the cutting blade passing through the guide member, the folding means positioned adjacent said guide member, and for folding the cutting blade to a predetermined angle, the folding means including at least two folding members;    first driving means configured to engage said folding means, for revolving and driving the folding means against the cutting blade; and    second driving means configured to engage said folding means and move at least one of the folding members of said folding means to a position adjacent the cutting blade, prior to driving the first driving means;    wherein said folding means comprises a supporting frame comprised of at least two plate shaped members, the guide member positioned between the at least two plate shaped members; a fixing body having a predetermined length and a guide entrance operatively connected with said guide member, wherein ends of the fixing body are rotatably fixed to the supporting frame, the fixing body having a guide slot formed therein for insertably receiving a folding member; and a pair of rotary bodies, rotatably connected to the ends of the fixing body for revolving the folding members, said pair of rotary bodies having a pair of guide holes formed therein for insertably receiving the folding members.
