Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, following embodiment is hereby enumerated, and coordinate
Detailed description are as follows for attached drawing：
Refer to Fig. 1 to 3, a kind of tool of processing sheet foursquare arc, including cylindric tool body 1, the tool
It is arc-shaped column piercing tip 8 that 1 lower end periphery surface of ontology, which is equipped with cross section, and the piercing tip 8 includes upper installation
Portion and lower blade, the lower blade protrude from the lower face of the tool body 1.The radian and inner circle radius of the lower blade with
Thin plate foursquare arc process matches, and the radian a of the lower blade can be slightly larger than the radian of processing sheet fillet.
Further, 1 lower end of the tool body can be equipped with shoulder 2, the top surface of the piercing tip 8 and the shoulder 2
End face connects.Shoulder 2 bears reaction force when piercing tip 8 is punched.
Further, the radian of the upper mounting portion of the piercing tip can be more than the radian of the lower blade.
Further, it is blind can be equipped with the upper, middle and lower segment ladder that diameter is sequentially increased for 1 bottom centre of the tool body
The epimere in hole, the blind hole can be threaded hole, can be equipped with spring 5 in the stage casing of the blind hole, can be set in the hypomere of the blind hole
There is spring bearer plate 3；The spring and the spring bearer plate 3 can be socketed on the first screw 4；First screw 4 screws in institute
It states in threaded hole.
Further, the lower face center of the spring bearer plate 3 can be recessed into the first groove, first screw 4 upwards
Nut be located in first groove；First groove can be matched with the positioning pin on workpiece positioning tool.
Further, it may also include the blade fixation clip 6 engaged with 8 outer round surface of the piercing tip, the punching
Cutting edge 8 and the blade fixation clip 6 can be affixed by the second screw 7 and 1 lower end periphery surface of the tool body.
Further, second screw 7 can be multiple, can be uniformly distributed along the circumferential direction of the piercing tip 8.
