Based on the embodiments of the present invention, other embodiments used by those skilled in the art without any creative effort belong to the protection scope of the present invention.
Example 1:
as shown in fig. 2, a riveting tool includes cope match-plate pattern 6 and lower bolster 1, includes: an upper punch assembly comprising a first upper punch 8 and a second upper punch 10 mounted on said upper die plate 6; the upper stripper plate 15 is provided with two first through holes, and the first upper punch 8 and the second upper punch 10 are respectively and correspondingly arranged in the two first through holes; the upper spring 11 is used for connecting the upper stripper plate 15 to the upper template 6; the first upper punch 8 and the second upper punch 10 are both positioned in the first through hole of the upper stripper plate 15 before riveting.
A lower punch assembly comprising a first lower punch 19 and a second lower punch 20 mounted on the lower die plate 1; the first lower punch 19 is matched with the first upper punch 8, and the second lower punch 20 is matched with the second upper punch 10 to realize the riveting of the workpiece 12; the first lower punch 19 and the second lower punch 20 are both located in the second through hole of the lower stripper plate 5 before riveting.
The lower stripper plate 5 is provided with two second through holes, and the first lower punch 19 and the second lower punch 20 are respectively and correspondingly arranged in the two second through holes; and the lower spring 16 is used for connecting the lower stripper plate 5 to the lower template 1. And a positioning column for positioning the workpiece 12 to be riveted is arranged on the lower stripper plate 5.
When the invention is applied, a workpiece 12 to be riveted is placed on the lower stripper plate 5 through the positioning column, wherein it should be noted that the rivet 9 below the workpiece 12 is pre-matched with the riveting hole on the workpiece 12 and then placed in the second through hole, and the rivet 9 above the workpiece 12 is directly placed in the riveting hole on the workpiece 12.
At this moment, the upper die plate 6 moves downwards under the driving of the punch press slider, firstly, the upper stripper plate 15 contacts with a product of a workpiece 12 to be riveted, the upper die plate 6 continues to move downwards, the upper stripper plate 15 presses the product of the workpiece 12 to be riveted to move downwards together, the upper spring 11 and the lower spring 16 are both shortened after being pressed, the upper stripper plate 15 and the lower stripper plate 5 respectively axially retreat, and the first upper punch 8 and the second upper punch 10 in the upper stripper plate 15 and the lower stripper plate 5 are respectively matched with the first lower punch 19 and the second lower punch 20 and simultaneously press two ends of a rivet 9 on the workpiece 12 to rivet the rivet 9 tightly. When the punch stroke moves to the top dead center, the upper stripper plate 15 and the lower stripper plate 5 are reset under the action of the upper spring 11 and the lower spring 16, and the riveted workpiece 12 is ejected, as shown in fig. 3. And taking the workpiece, remounting the workpiece, and repeating the steps.
It should be noted that the structure provided by the present embodiment can also rivet a product with two rivets 9 on the same side of the workpiece 12.
In the present embodiment, the length of the first upper punch 8 is shorter than the length of the second upper punch 10, and the length of the first lower punch 19 is longer than the length of the second lower punch 20; or the length of the first upper punch 8 is longer than the length of the second upper punch 10, and the length of the first lower punch 19 is shorter than the length of the second lower punch 20. In this configuration, the rivet 9 is placed on both sides of the workpiece 12, and the first lower punch 19 and the second lower punch 20 need to reserve a space in which the rivet 9 on the lower side of the workpiece 12 can be placed in the second through hole in which the shorter punch is placed before the riveting.
And in order to improve the riveting quality, the diameters of the first upper punch 8, the first lower punch 19, the second upper punch 10 and the second lower punch 20 are equal to the diameter of the rivet 9, and the diameters of the first through hole and the second through hole are 1-2mm larger than the diameter of the rivet 9. Thus, even if the rivet 9 placed in the second through-hole falls from below the workpiece 12, the rivet 9 is automatically anchored into the workpiece 12 by the upper and lower punches at the time of riveting.
In the present embodiment, the sum of the lengths of the first upper punch 8 and the first lower punch 19 is equal to the sum of the lengths of the second upper punch 10 and the second lower punch 20. This configuration is adopted when the two rivets 9 are the same length.
