The lower end of the formed punch is docked respectively in side, is equipped with a circle positioned at the upper surface of through-hole aperture outer ring mold insert and squeezes muscle, the extruding
The inner ring of muscle is an inner conical surface, and the outer ring of inner conical surface extends into external conical surface in one week.
Its further technical solution is:
The plate to be riveted is equipped with the circular hole being connected with the through-hole, and Circularhole diameter is equal to the outer diameter for squeezing muscle.
The extruding muscle and mold insert are integrally formed, and are squeezed muscle and are used superhard cold-punching mold steel.
The angle that the inner conical surface and horizontal plane are formed is 15 °, and the angle that the external conical surface is formed with horizontal plane is
122°。
The aperture of through-hole is 5.6cm in each mold insert, and squeezing the width of the inner conical surface of muscle in the horizontal direction is 0.75cm,
Squeezing the distance of top to the mold insert upper surface of muscle along the vertical direction is 0.2cm.
The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, easy to operate, squeezes muscle by being arranged in the through-hole outer ring of mold insert, squeezes
Compressive plane between rivet and mold insert is become cambered surface by plane by the inner conical surface and external conical surface of muscle, is acted in formed punch punching press
Under, the torsion and thrust of rivet are increased, some materials for squeezing muscle is squeezed into the circular hole of plate to be riveted, is enhanced
Cooperation between rivet and plate to be riveted improves the quality and service life of part.

Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, the stamping riveting mold of the present embodiment, including mutually matched lower mold assemblies and upper
Membrane module, upper die component include die shank 2, and lower surface is equipped with upper die holder 1, and 1 lower surface of upper die holder passes through the fixed peace of upper padding plate 3
Equipped with upper clamp plate 4, interval is equipped with multiple formed punches 5 in the middle part of upper clamp plate 4；Lower mold assemblies include lower die holder 9, under upper surface passes through
Backing plate 8 is equipped with the concave template 7 for placing plate 6 to be riveted, and the identical mold insert 10 of multiple structures is installed at interval in concave template 7, often
Perforative through-hole 11 is offered in a mold insert 10, is docked the lower end of formed punch 5 above 11 aperture of through-hole respectively, is located at 11 aperture of through-hole
The upper surface of outer ring mold insert 10 is equipped with a circle and squeezes muscle 12, and the inner ring for squeezing muscle 12 is an inner conical surface 121, inner conical surface 121
Outer ring extend into external conical surface 122 within one week.
