Preferably, described sheath comprises body and is located at three claws of described body lower end, and described red needle is positioned at described body, and the lower end of described red needle is through the center of three described claws, and three described claws are positioned on same circumference and uniformly-spaced and arrange.
Preferably, in three described claws, the angle between every two adjacent claws is 60 °.
Preferably, the length of described body is 33-37mm, and the length of described claw is 5-9mm.
Preferably, described patrix also comprises die shank, and described die shank is fixed on the top of described cope match-plate pattern.
Preferably, guide pillar is also installed on described fixed head and stripper, described die is provided with the locating hole with described guide pillar corresponding matching.
Preferably, on described the first upper padding plate, be also provided with and re-pack.
Compared with prior art, the punch structure of spring shim of the present utility model, by sheath is set, utilizes sheath to protect red needle and can make red needle be not easy bending and broken needle, has strengthened durability; Draw shaven head by setting, utilize the centre bore that draws bare headed alignment springs pad, improved the aperture in drilled hole and the accuracy of pitch-row on spring shim, reduced the scrappage of product, reduced cost.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
