Preferably, the upper die is also provided with a pressing side cutter, and when the upper die and the lower die are assembled, the side edge of the pressing side cutter abuts against the movable clamping block, so that the pressing side cutter and the static clamping block press the ball head rivet and the sheet metal part.
More preferably, the lower die is also provided with a positioning block for assisting the positioning and pressing of the pressing side knife.
More preferably, the upper part of one side of the movable clamping block facing the pressing side knife is processed into a positive slope, and the bottom of one side of the pressing side knife, which is correspondingly abutted with the movable clamping block, is processed into a negative slope.
Preferably, the tail end of the push rod is further connected with a baffle, and a return spring is further arranged between the baffle and the lower die.
More preferably, a positioning seat is further fixedly arranged on the side edge of the lower die, a clamping cam is rotatably arranged on the positioning seat, a cam surface of the clamping cam abuts against the baffle, and a handle is further arranged outwards on the clamping cam.
When the riveting die disclosed by the invention specifically works, the movable clamping block is pushed to open by the push rod, then the ball head rivet and the sheet metal part are placed, then the push rod is reset, so that the movable clamping block presses the ball head rivet, the upper die moves downwards, the pressing side knife can prop against the movable clamping block to tightly press the ball head rivet and the like, and meanwhile, the riveting punch downwards completes the riveting action.
Compared with the prior art, the invention has the following advantages:
(1) The movable clamping blocks and the static clamping blocks are adopted to movably compress and fix the ball head rivet and the like, so that the contact area between the ball head rivet and the clamping block assembly can be increased, and the ball head of the ball head rivet is not easy to deform and stable in size when being punched.
(2) The whole die is simple to operate and convenient to take materials.
(3) The riveting strength is greatly improved, and the ejection force and the torsion are both improved and stable.
