Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being introduced further and illustrating, but being not limited to this.
As shown in Figure 1 to Figure 3, a kind of wire stretching traction of the utility model fixture, comprises chuck body 1, wedge 2, replaceable cushion block 4, driving lever 5, handle 6; Chuck body 1 is provided with the die cavity 11 for through wire rod 3 and end face being interior inclined-plane, and end is provided with the towing pad 12 connecting traction piece; Die cavity 11 bottom surface is provided with groove 13; In the outer inclined-plane of wedge 2 and die cavity 11, inclined-plane is slidably matched; In die cavity 11, inclined-plane is identical with the angle β of inclined-plane in wedge 2 and bottom surface with the angle of bottom surface, and angle β=9 ~ 16 °; The bottom surface of wedge 2 is provided with matsurface (the present embodiment is the matsurface 21 with curl), and matsurface compresses wire rod 3, and when stretching wire rod 3 or top pressure wedge 2, wedge 2 and chuck body 1 are by the formation inclined-plane self-locking of inside and outside inclined-plane.
Replaceable cushion block 4 is provided with arcwall face 41, lug boss 42; Arcwall face 41 coordinates with wire rod 3, its radius of curvature 0 ~ 0.5mm larger than the radius of wire rod 3; Lug boss 42 coordinates with groove 13, replaceable cushion block 4 can not be moved in die cavity 11 horizontal direction, and be fixed on chuck body 1 by screw 43.
