Please continue to consult Fig. 7, Fig. 8 and Fig. 9 a and Fig. 9 b, as shown in the figure, in adding man-hour, cutter 2 is positioned on the clamping device 28, continue and import by the mother metal 291 of feeder 29 with conductance type pinhead, be to be pressed into mother metal 291 from the forward and backward side of mother metal 291, form lead angle 292, lead angle 293, so that make cutting knife locate to cut off from mother metal 291 lead angles (292,293) in mother metal 291 by two relative cutters 2 in position.
Please continue to consult Figure 10 a and Figure 10 b, as shown in the figure, be second preferred embodiment of the present invention, set acting surface also can be made into circular arc to be applied on the rounded mother metal of section 391 on its forming section of cutter of the present invention, in view of the above, the acting surface of cutter of the present invention can be at the section configuration of mother metal and is done design.
Therefore,, and the present invention and prior art are done one relatively, can learn that the present invention has advantage and effect what follows by above-mentioned explanation:
(1) four set to the concave on this cutter 2 first forming section 21, second forming section 22, the 3rd forming section 23 and the 4th forming section 24, when this cutter 2 is pressed into mother metal 291, first flanging 251, second flanging 252, the 3rd flanging 253, Fourth Fold 254, flanging 261, flanging 262, flanging 271 and flanging 272 that it intersects, the unnecessary parts in the oppressed back of mother metal 291 are prolonged to the first channel 25a and second channel 25b be difficult for archives (292,293) in producing salient point, and then make the shortcoming of this conductance type pinhead unlikely generation such as prior art product when assembling.
(2) in adding man-hour, be to be pressed into mother metal 291 from the forward and backward side of mother metal 291 by two relative cutters 2 in position, and form lead angle 292, lead angle 293 in mother metal 291, first composition surface 26 of this cutter 2, whence and second composition surface 27 can make the relative cutter 2 in two positions after being pressed into mother metal 291, has butt joint driving fit effect, in detail, the lead angle of mother metal 291 (292,293) promptly is formed in the forming section (21,22,23,24) of cutter 2, thereby has preferable molding effect; And two relative cutters 2 in position also are difficult for because of locational deviation, and make mother metal 291 produce flexural deformation when cutter 2 is pressed into.
(3) in adding man-hour, owing to the unnecessary part in mother metal 291 oppressed backs is extended to the first channel 25a and second channel 25b, and average distribution, make the effect of this mother metal 291 because of the material extrusion modling, cause mother metal 291 length to increase, reduce material cost then.
(4) on mother metal 291, form lead angle (292,293), only need use two cutters 2 that the position is relative, and only need time processing to achieve the goal, if use four cutters 2 that the position is relative, 291 processing also can achieve the goal to mother metal in the mode of twice processing, and more can prolong the service life of cutter 2 simultaneously.
The above only is preferable feasible embodiment of the present invention, and the variation that above-mentioned method, shape, structure, the device of all the present invention of utilization done all should be contained in the interest field of the present invention.
