Combined cutter for increasing local cutting edge flat angles

The utility model discloses a combined tool for increasing a flat angle of a local cutting edge, belongs to the technical field of die machining, and aims to solve the technical problems that the service life of a tool edge is shortened and the machining efficiency and precision are not high due to the shape characteristics of a product when the combined tool in the prior art is used for cutting the shape of a part with a special shape or a larger angle. The combined tool comprises a lower blade and an upper blade capable of doing reciprocating motion in the vertical direction, the upper bladeis provided with an arc-shaped cutting edge with the two ends bent downwards, a first special-shaped groove is formed in the side face of the arc-shaped cutting edge, and a second special-shaped groove opposite to the first special-shaped groove is formed in the side face of the cutting edge of the lower blade. 本实用新型公开了模具加工技术领域的一种增加局部刃口平角的组合刀具，旨在解决现有技术中组合刀具在对形状特异或角度较大的零部件切外形时，刀口由于产品形状特点导致缩短使用寿命以及加工效率和精度不高的技术问题。所述组合刀具包括下刀
