Detailed Description

As shown in fig. 1-3, a chamfered edge, hypotenuse furniture screw stamping die, including module one, module two and module three that correspond the technology step order, module one is again including last mould 1 and lower mould 2 that corresponds the punching press, module two is again including last mould two 3 and lower mould two 4 that correspond the punching press, module three is again including last mould three 5 and lower mould three 6, it is equipped with the chamfer groove 7 that corresponds the screw bottom on the punching press face to go up mould one 1, lower mould one 2 is equipped with the radius groove 8 that corresponds the screw top, and radius groove 8 and chamfer groove 7 correspond the outer fringe structure of screw portion 13 department from top to bottom respectively, the last small radius of the chamfer and connecting portion 14 department that becomes the top of processing. The upper die II 3 and the upper die III 5 are provided with die pressing grooves 9 for correcting and positioning on the punching surface, the lower die II 4 is provided with chamfered grooves 10 on the punching surface, the center of the bottom of each chamfered groove 10 is provided with a conical prefabricated head 11, and the prefabricated heads 11 are punched to form conical holes for facilitating subsequent processing. And the punching head 12 for processing the hexagon socket shape is arranged on the punching surface of the lower die III 6, so that the processing of the hexagon socket groove is completed.

The radial section of the chamfer groove 7 is in a shape of an inverted isosceles trapezoid, and the included angle of the side edge of the radial section of the chamfer groove 7 is 70 degrees.
