A cutter for manufacture of springs comprises a cutter body, a cutting edge, an inclined edge, a transition arc, and a cutting edge groove, wherein the cutter body is in a cuboid shape, the cutting edge is located at the upper end of the cutter body, the inclined edge is located on the upper left portion of the cutter body, the cutting edge groove is arranged in the middle of the cutting edge, and the transition arc is a curve arc-shaped edge and is located between the inclined edge and the cutting edge.
Description
Technical field
The utility model relates to the spring tool of production, particularly a kind ofly makes the cutter that spring is used.
Background technology
Spring steel mainly is that good elasticity is arranged, and works under the dynamic loading environmental condition owing to it again, so to the material of making spring is topmost high yield strength should be arranged; When bearing heavy load, do not cause plastic deformation; The fatigue strength of Ying Yougao has long service life under the load repeated action; And enough toughness and plasticity arranged; in case suddenly brittle failure under impact force action, because the characteristic of spring, the cutter that is used for cutting off during like this to the manufacturing spring requires just higher; the cutter that uses now often can produce irregular section, the quality that the shadow spring is produced when the cutting spring.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of cutter that spring is used of making is provided, and it can produce neat section when the cutting spring.
The technical solution of the utility model is: a kind ofly make the cutter that spring is used, it comprises cutter hub, blade, hypotenuse, transition arcs, blade groove, cutter hub is rectangular shape, blade is positioned at the upper end of cutter hub, hypotenuse is positioned at the upper left quarter of cutter hub, there is a blade groove at the middle part of blade, and transition arcs is crooked arc-shaped side, and transition arcs is between hypotenuse and blade.
The utility model compared with prior art has following features: cutter hub is fixed on the spring generation machine, the spring that blade groove on the blade can stably cut generated, transition arcs between hypotenuse and blade forms a space, allow generated spring pass, it can produce neat section when the cutting spring.
Below in conjunction with the drawings and specific embodiments detailed construction of the present utility model is further described.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Accompanying drawing 3 is the top view of accompanying drawing 1.
The specific embodiment
As shown in drawings: a kind ofly make the cutter that spring is used, it comprises: cutter hub 1, blade 2, hypotenuse 3, transition arcs 4, blade groove 2-1, cutter hub 1 is rectangular shape, blade 2 is positioned at the upper end of cutter hub 1, hypotenuse 3 is positioned at the upper left quarter of cutter hub 1, there is a blade groove 2-1 at the middle part of blade 2, and transition arcs 4 is crooked arc-shaped side, and transition arcs 4 is between hypotenuse 3 and blade 2.
Operation principle of the present utility model and using method are: cutter hub 1 is fixed on the spring generation machine, the spring that blade groove 2-1 on the blade 2 can stably cut generated, transition arcs 4 between hypotenuse 3 and blade 2 forms a space, allows generated spring pass.
