The technical scheme of the utility model is as follows: the riveting punch assembly is fixed on an upper template through screw connection, a guide post and an upper pressing plate nitrogen spring are also installed on the upper template, an upper pressing plate descending limiter and an upper pressing plate ascending limiting screw are both fixedly locked on the upper template, a feeding device slideway is fixedly locked on a fixed plate of a moving slideway of a push-pull cylinder through screws, the feeding push-pull cylinder is fixedly arranged on a floating plate through bolts, the guide post of the floating plate, a limiting device of the floating plate, the nitrogen spring of the floating plate and the guide of an upper template and a lower template are all installed on a lower template base plate, the floating plate is installed on the lower template through the floating plate guide post, a material returning plate screw is used for limiting the stroke of the floating plate, a lower die fixed plate and a die base plate are connected together through screws, and then the lower template base plate and the die base plate are fixedly connected through screws.

The beneficial effects of the utility model are as follows: the novel die structure can completely replace the traditional press riveting process, has the characteristics of high production efficiency and simple operation, and is quick in production beat, small in occupied area and stable in quality. The investment is far smaller than that of a special press riveting machine.

Description of the drawings:

FIG. 1 is an overall schematic of the present utility model;

FIG. 2 is a top view of the present utility model;

FIG. 3 is a side view of the present utility model;

FIG. 4 is a front view of the present utility model;

FIG. 5 is a schematic cross-sectional view of a mold according to the present utility model

The specific embodiment is as follows:

The utility model is further described below with reference to the accompanying drawings:

As shown in the figure, 1 is an upper die plate of a press riveting die, 2 is a fixed plate of a moving slideway of a push-pull cylinder, 3 is a nitrogen spring of an upper press plate, 4 is a guide post of the upper press plate, 5 is a lower die plate of the press riveting die, 6 is a lifting rod of the upper die plate of the press riveting die, 7 is a fixed plate of the lower die plate of the press riveting die, 8 is a backing plate of the press riveting die, 9 is a press plate, 10 is a float plate, 11 is a slideway of a feeding device, 11-1 is a moving slideway of the push-pull cylinder, 11-2 is a push-pull cylinder of the feeding device, 12 is a lifting rod for lifting the lower die plate of the press riveting die, 13 is a guide post of the float plate, 14 is a limiting device of the float plate, 15 is a nitrogen spring of the float plate, 16 is a guide of the upper die plate and the lower die plate, 17 is a return plate screw of the float plate, 18 is a descending limiter of the upper press plate, 19 is an ascending limiter of the upper press plate, 20 is a punch head assembly, 20.1 is a punch head pressing A,20.2 is a rivet head, and 20.3 is rivet C.

As shown in fig. 1, the self-designed riveting punch assembly 20 and the symmetrical sides 4 are all connected to the upper die plate 1 by screws, the guide post 4 and the upper pressure plate nitrogen spring 3 are also arranged on the upper die plate 1 to respectively provide guiding and power sources for the pressure plate, and the upper pressure plate descending limiter 18 and the upper pressure plate ascending limiting screw 19 are both fixedly locked on the upper die plate 1 to respectively play roles of pressure plate ascending limiting and descending limiting. The feeding device slideway 11 is fixedly locked on the fixed plate 2 of the moving slideway of the push-pull cylinder through a screw, and finally the feeding push-pull cylinder 11-2 is fixedly arranged on the floating plate 10 through a bolt, so that all feeding devices are assembled. And then the guide post 13 of the floating plate, the limiting device 14 of the floating plate, the nitrogen spring 15 of the floating plate and the guide 16 of the upper and lower templates are all arranged on the lower die bottom plate 5, the floating plate 10 is arranged on the lower template through the floating plate guide post 13, and the material returning plate screw 17 is used for limiting the travel of the floating plate 10, so that the assembly of all the floating devices is completed. Finally, the lower die fixing plate 7 and the die backing plate 8 are connected together through screws, and then the lower die bottom plate 5 and the die backing plate 8 are fixed in a linked manner through screws, so that the effect of heightening the die is achieved. After the assembly is completed, the upper die plate lifting rod 6 of the riveting die and the lower die plate lifting rod 12 of the riveting die are respectively connected to the upper die plate 1 of the riveting die and the lower die plate 5 of the riveting die through bolts, so that the lifting effect is achieved, all the riveting tools are assembled, and the parts can be riveted by installing the riveting tools on a punching machine.

The specific working principle is as follows:

The working principle is that a punch is utilized to drive a die, a press riveting punch is locked and attached on an upper die plate in advance, a workpiece needing press riveting is placed on a feeding mechanism and is fed into the die, and when the punch is pressed down to reach a die closing point, the press riveting punch is pressed into the workpiece, so that the fixation of the embedded small piece is completed. After the punching machine is opened, the floating plate is jacked up, press riveting is completed, and the finished piece can be taken out.

The specific using method comprises the following steps:

And fixing the assembled press riveting tool on a proper punch, lifting the punch after fixing, putting the part to be press riveted into a pressing plate of the press riveting die, and fixing the part through a positioning device. The built-in block to be riveted is placed on a slideway of a push-pull cylinder, the push-pull cylinder is started, the built-in block is fed into a part by the push-pull cylinder, a punch descends, the punch ascends again after reaching a bottom dead center of a die, and the part can be taken out after the push-pull cylinder returns, so that the press riveting of a finished product is completed.
