Referring to fig. 1 and 2, prior to riveting, the operator first places the spring plate on the die holder 2 and places the tips of the contact rivets on the apertures in the spring plate. Then the die shank 5 is pressed downwards, the pressing plate 4 firstly presses the spring 9, the die shank 5 continues to be pressed downwards, the pressing spring 9 is pressed to deform, the punch 7 slides downwards in the through hole 8, and the contact rivet and the spring piece are pressed into a whole, so that riveting is realized. After riveting, the die shank 5 rises, and the pressure spring 9 drives the pressure plate 4 to rise.

Referring to fig. 2, the punch 7 includes a punch core 15 and a sleeve 16 coaxially disposed, and the punch core 15 is slidably disposed through the sleeve 16. Due to the split arrangement of the punching core 15 and the sleeve 16, when the punching core 15 is damaged, an operator only needs to replace the punching core 15, the sleeve 16 does not need to be replaced, and materials are saved.

Referring to fig. 2, a limiting head 24 is welded at one end of the punch core 15, which is far away from the bottom plate 1, the diameter of the limiting head 24 is larger than the inner diameter of the sleeve 16, and the limiting head 24 is used for limiting the punch core 15, so that the possibility that the punch core 15 falls from the through hole 8 when the die shank 5 rises is reduced. The inner diameter of the sleeve 16 is equal to the outer diameter of the punching core 15, so that the punching core 15 is restrained, and the possibility that the two ends of the punching core 15 are stressed to be bent and deformed when the punching core 15 rivets the contact rivet is reduced.

Referring to fig. 2, the through hole 8 is in a step shape, the through hole 8 is in a large-end-up shape, the sleeve 16 is slidably connected in the hole body with the larger inner diameter of the through hole 8, and the punching core 15 and the hole body with the smaller inner diameter of the through hole 8 are in a clearance arrangement. The clearance setting makes more convenient when dashing in the core 15 inserts in through-hole 8, has alleviateed the possibility that dashes core 15 and through-hole 8 lateral wall and bump and lead to damaging.

Referring to fig. 2, one end of the hold-down spring 9 away from the hold-down plate 4 is welded to the upper press block 11. Go up briquetting 11 and pressure strip 4 same one side and be equipped with vertical stopper 12, the one end bolt of stopper 12 is on pressure strip 4, and the other end is opened has waist type groove 13, and the length direction of waist type groove 13 is on a parallel with the length direction of drift 7, goes up one side of briquetting 11 and is equipped with spacing axle sleeve 14, and spacing axle sleeve 14 is located waist type groove 13 and rather than sliding connection, and spacing axle sleeve 14 bolt is on last briquetting 11.

Referring to fig. 1, when the punch 7 rivets the contact rivet and the spring plate completely, the limiting shaft sleeve 14 is just attached to the side wall of the bottom end of the kidney-shaped groove 13, so that the punch 7 is limited, the possibility of damage caused by excessive downward pressing of the punch 7 is reduced, and the possibility of crushing the contact rivet and the spring plate by the punch 7 is also reduced.

Referring to fig. 1 and 2, two guide pillars 21 penetrate through the bottom plate 1, the two guide pillars 21 are symmetrically arranged about the riveting hole 3, the guide pillars 21 are vertically arranged, the guide pillars 21 are in threaded connection with the bottom plate 1, a guide hole 22 is formed in the pressing plate 4, and the guide pillars 21 penetrate through the guide hole 22 in a sliding manner. The cooperation of guide post and guiding hole 22 plays the guide effect to the up-and-down motion of die shank 5, simultaneously, has improved the axiality of punching core 15 and riveting hole 3.

Referring to fig. 1 and 2, a linear bearing 23 is arranged in the guide hole 22, the linear bearing 23 is bolted on the clamping plate, and the linear bearing 23 is slidably sleeved on the guide post 21. The linear bearing 23 is provided to make the sliding fit between the guide post 21 and the guide hole 22 smoother.

The implementation principle of the embodiment is as follows: before riveting, an operator first places a spring plate on the die holder 2 and places contact rivets on small holes in the spring plate. Then, the die shank 5 is pressed down, the pressing plate 4 first contacts the contact spring piece, and the contact rivet enters the hole body with the smaller inner diameter of the through hole 8. The die shank 5 continuously presses downwards, the pressing spring 9 is pressed to deform to generate elastic force to push the pressing plate 4 to press the spring piece, the punch 7 slides in the upper pressing block 11, and when the limiting head 24 abuts against the die shank 5, the die shank 5 pushes the punch core 15 to rivet downwards, so that riveting between the contact rivet and the spring piece is realized. Through the pre-compaction of pressure strip 4 to the spring leaf, then drift 7 carries out the riveting to spring leaf and contact rivet again, when having reduced drift 7 riveting contact rivet, the possibility that other positions of spring leaf take place to warp has reduced the riveting and has produced the possibility that influences to the technical indicator of spring leaf. When the punch 7 slides in the upper pressing block 11, the limiting sleeve 16 slides up and down in the kidney-shaped groove 13, and when the spring piece and the contact rivet are completely riveted, the outer side wall of the limiting shaft sleeve 14 is just attached to the bottom end of the side wall of the kidney-shaped groove 13, so that the possibility of damage caused by excessive riveting of the punch 7 is reduced. After the riveting is finished, the die handle 5 rises, the compression spring 9 recovers, the compression plate 4 releases the spring piece, and the punch 7 drives the limiting shaft sleeve 14 to slide downwards to the bottom end of the waist-shaped groove 13. The operator can take out the spring piece and the contact rivet which are riveted together.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
