Detailed Description

As shown in fig. 1, the leaf spring clips are U-shaped with bolt holes 16 (some clips are not) on both sides of the U-shape and rivet holes 17 (some clips are not) on the bottom of the U-shape.

As shown in fig. 2, two clip bolt holes 15 are formed in the semi-finished product of the blanking and punching of the steel plate spring clip, and are symmetrical with the center of the whole length; the two ends are circular arcs and are symmetrical with the center of the whole length.

The working principle is as follows: as shown in fig. 3, the upper die is fixed on the slide block of the punching machine, the lower die is fixed on the worktable of the punching machine, and the guide post 10 and the guide sleeve 11 are fixed between the upper die and the lower die.

The upper die comprises a die handle 1, an upper die plate 2, an upper die base plate 3, an upper die fixing plate 4, an upper die cutter 5 and an upper die punch 6.

The lower die consists of a lower die stripper plate 7, a lower die plate 8 and a lower die bottom plate 9.

As shown in fig. 3, a die shank 1 and an upper die plate 2 are welded together and fixed on a press slide, an upper die fixing plate 4 is fixed on the upper die plate 2 by bolts, and an upper die backing plate 3 is arranged in the middle and used for adjusting the height of the upper die fixing plate 4; the upper die fixing plate 4 is fixed with an upper die cutter 5 and an upper die punch 6 by fastening screws. As shown in figure 6, the upper die cutter 5 is X-shaped and is symmetrical by a central line, as shown in figure 7, the two upper die punches 6 are symmetrical by the central line of the cutter, and the guide effect of the guide pillar 10 and the guide sleeve 11 is added, so that the linear motion of the upper die (movable die) and the normal centering of the lower die (fixed die) are ensured, and the distance from the bolt hole to the top end of the semi-finished product after the clamp is discharged is ensured to be the same.

As shown in fig. 8, the lower die base plate 9 is fixed with the lower die plate 8 by bolts, the lower die stripper plate 7 is fixed with the lower die plate 8 by bolts, and the lower die stripper plate 7 is provided with grooves 14 for passing flat steel. And fixing a positioning sliding plate 12 on the lower die bottom plate 9 by using bolts, fixing a positioning plate 13 on the positioning sliding plate 12 by using bolts as shown in figure 4, and adjusting the positioning plate according to the required blanking length of the flat steel to determine the blanking length as shown in figure 5.

The using method comprises the following steps: as shown in fig. 3, the positioning plate 13 is adjusted and locked according to the required blanking length of the flat steel, the flat steel passes through the lower die stripper plate 7 and pushes against the positioning plate 13, and then the flat steel at the downward shearing end of the upper die (movable die) of the punch machine simultaneously punches the clip bolt hole (when the clip hole is not needed, the punch is removed). During blanking, the front end of a next blanking semi-finished product and the rear end of a previous blanking semi-finished product are subjected to punching and shearing at one time, and continuous punching and shearing operation is performed.

The die is suitable for processing the blanking of the U-shaped clamp of the steel plate spring.
