The specific embodiment

Like Fig. 1, the side view of the utility model embodiment; Patrix 100 parts have a upper padding plate 103, and the concora crush mould 101 of rectangular cross section has been fixed in the below of upper padding plate 103, and these concora crush mould 101 four sides are vertical plane, a moving skewback 130 are respectively arranged near on it.Moving skewback 130 is exerted pressure through the back-moving spring 140 that is fixed on upper padding plate 103, to such an extent as to abut against the plane all around of concora crush mould 101.Lower end at moving skewback 130 also has ramp 131.

On counterdie 200, have lower bolster 203, fixed concora crush pad 201 on this lower bolster 203, and decide skewback 230 around the concora crush pad 201.Wherein, product 300 is placed at concora crush pad 201 tops, and concora crush mould 101 is pressed on the position of concora crush pad 201, and the position that also is contact product 300 is a circumferentia form, because the riveted joint limit of product is inside flanging, and is distributed in outer edge.
