A gap G is reserved between the lower part of the male die fixing component and the upper surface of the discharging fixing plate.
The elastic assembly comprises a spring 9 and a positioning pin 10, the positioning pin extends into the second accommodating groove from the upper part of the upper die base for the convenience of assembly, the spring is sleeved on the positioning pin in the second accommodating groove, and an embedding groove 11 for embedding the lower end of the spring is formed in the upper surface of the ejection block so as to restrain the lower end of the spring and ensure the compression stability of the spring. An assembly groove 12 is formed in the upper surface of the upper die base above the second accommodating groove, a cover plate 13 is installed in the assembly groove, and the cover plate forms a sealing cover for the elastic assembly so as to be protected.
The male die fixing component comprises a fixing plate 14, a male die fixing plate 15 and a male die pressing plate 16.
The fixed plate is fixedly connected to the lower surface of the upper die base, and an accommodating space 17 for accommodating the male die fixed plate is formed in the fixed plate; after the fixed plate is assembled on the upper die base, the downward stroke of the ejection block is limited, and the placing space in the fixed plate is smaller than that of the ejection block, so that the ejection block is blocked by the fixed plate when moving downwards; the male die fixing plate is fixedly connected with the lower surface of the ejection block through a screw.
The male die pressing plate is fixedly connected with the lower surface of the male die fixing plate through screws, the upper end surface of the male die is propped against the lower surface of the ejection block, and the upper end part of the male die is limited by the male die fixing plate between the male die pressing plates; the upper end of the male die is step-shaped, a through hole 18 matched with the upper end of the male die is formed in the male die fixing plate and the male die pressing plate, and the through hole in the male die pressing plate is smaller than the through hole in the male die fixing plate, so that the upper end of the male die can be limited between the male die fixing plate and the male die pressing plate.

In order to prolong the service life and facilitate maintenance, a cushion block 19 with strong hardness is fixedly arranged on the upper surface of the discharging fixing plate, and the gap is reserved between the upper surface of the cushion block and the lower surface of the male pressure plate.
The design of the elastic overlapped riveting point height control structure mainly can realize the height control of the overlapped riveting point by controlling the height of the overlapped riveting convex die higher than the stripper plate, and mainly improves the following steps:
1) the height of the overlapped riveting point is always constant: due to the adoption of an elastic control structure, the height of the stacked riveting male die out of the stripper plate, namely the height of the stacked riveting point, is completely determined by the clearance arrangement on the die; when the mould closure height changes, fold and rivet the terrace die and can automatic withdrawal, avoid because the closed height adjustment of punch press and cause fold the height variation of riveting point. The working principle is as follows: the stripper plate, the stripper fixing plate and the cushion block move upwards under the action of the punch press, and the gap G value changes; when the cushion block contacts the male die pressing plate in the upward movement process, namely the G value is zero, the male die fixing plate and the ejection block are pushed to move upwards; at the moment, the height H of the male die is higher than that of the stripper plate, namely the height of the rivet stacking point also reaches the highest value, and the height does not change along with the downward movement of the punch. When the punch goes upward, the spring assembly can push the ejection block to reset the riveting male die and the male die fixing plate. The height "H" of the punch above the stripper plate is determined by the gap "G", and when the value of "G" is zero, the height "H" of the punch above the stripper plate will not change.
2) The precision requirement on the stamping equipment is low: the bottom dead center precision of the punch can be displaced due to the change of the punching speed, and the situation that the overlapped riveting point is punched can occur in serious cases, so that the female die is blocked and the die is damaged. Due to the adoption of the maximum value of the height of the overlapped riveting point limited by the depth control structure of the elastic overlapped riveting point, after the maximum value is reached, the depth of the overlapped riveting point cannot be changed due to the displacement of the bottom dead center of the punch; thereby effectively avoiding the situation of tension fluctuation caused by the speed change of the punch; the influence of the equipment precision on the height of the overlapped riveting point is eliminated.
3) The quality and stability of the product are high: the constant riveting point height improves the stability of the product tension, reduces the rejection rate of the product, and is particularly suitable for the debugging and material changing processes.
