A kind of rotary-cutting type bead cutter
Technical field
The utility model relates to metal sheet metal component process equipment, is specifically related to a kind of rotary-cutting type bead cutter.
Background technology
Because metal stretching spare need cut unnecessary rim charge and carry out shaping through the out-of-flatness of process back edge.Generally speaking, cut edge, utilize common punch press to accomplish the shear operation for metal stretching spare, need through side cut, the step of shaping, then according to the shape of this tensioning member, characteristics need to divide the process of side cut for several times on punch press; The problem that this side cut operation exists is: complex procedures, inefficiency, production cost height, in addition, because the common punch press of operation is worked repeatedly; And rely on manual operations, labour intensity is bigger, has slightly and does not note; Will lead to the accident of hindering hand, the accident that finger is cut off happens occasionally.
Utilization has the bead cutter of stretching shaving die then can avoid above problems, and the structure of stretching shaving die has often determined the performance of bead cutter, for example; China utility model patent Granted publication CN26663050Y; The utility model name is called: " stretching side cut compound die ", and Granted publication day is: on December 15th, 2004, this stretching side cut compound die comprises the die that is shaped on the shape chamber; Can with the blank holder of the pressing on die surface; Be positioned at blank holder, can go deep into the punch in shape chamber, its improvement is: said die band side cut cutting edge, and said punch and edger are fixed together; And when punch is positioned at die shape chamber extreme position, the cutting edge of edger be positioned at die side cut cutting edge to cutting complete position.Like this, during punch process, at first by die and blank holder sheet metal is compressed, then punch gos deep into die shape chamber gradually, with the sheet metal press forming.When punch moves near extreme position with respect to die, the cutting edge of edger and die side cut cutting edge will be pressed in the metal edge excision at blank holder place, thereby once accomplish the work of drawing and side cut; Adopt the bead cutter of said structure stretching side cut compound die can solve metal stretching spare cut edge inefficiency and the problem of poor stability in the operation to a certain extent; But; Because the stretching side cut composite die of this kind structure has only its die to have this processing stations of side cut cutting edge; Therefore; The operating efficiency of its side cut is lower, and simultaneously also because have only a side cut cutting edge processing stations, adopt said structure stretching side cut compound die bead cutter the workpiece that can process also receive bigger restriction.
