Described knife line is V-knife line.
Described V-knife line is made up of first edge of a knife and second edge of a knife, and described first edge of a knife and second edge of a knife it Between angle be 30-60 °.
Used as preferred technical scheme, the angle between the first described edge of a knife and second edge of a knife is 45 °.
The width in described knife line gap is 1-3mm.
Described knife line is U-shaped knife line.
Detent is offered on described die shoe.The detent is adapted with the shape and size of conducting foam, Conducting foam is placed in detent, is accurately positioned with to conducting foam.
The utility model in practical application, conducting foam is placed in the detent on die shoe, upper bolster to Lower motion, opening tooth trace cutting die is die cut to conducting foam, and multiple tooth traces being separated from each other are cut out in the side of conducting foam.
Compared with prior art, the utility model has the characteristics that:
1) because multiple tooth traces of the conducting foam side after cross cutting are separated from each other, conducting foam is made to be not only easy to bending, Meanwhile, the conductive fabric between adjacent tooth trace is still wrapped in foam, thus is not in the segregation phenomenon of conductive fabric and foam, it is ensured that The electric conductivity and stability in use of conducting foam;
2) detent on die shoe can be accurately positioned to conducting foam, improve the precision of cross cutting, and protect The homogeneity of product after each cross cutting is demonstrate,proved.
