Abstract

The invention discloses a nut cap riveting die which comprises an upper die and a lower die, wherein the lower die comprises a positioning board arranged on a base plate; a rectangular groove is arranged in one surface, which is in contact with the base plate, of the positioning board,,and a through hole for placing a workpiece is arranged in a middle position of the rectangular groove of the positioning board; plunger chips are respectively arranged in the rectangular groove and positioned in two sides of the through hole; a plunger chip compressed spring is arranged between each plunger chip and the positioning board; inclined wedges matched with the plunger chips are arranged on the upper die, and the inclined wedges enable the plunger chips to extrude the workpiece through extruding the plunger chip via the tail ends for realizing riveting. The nut cap riveting die has a simple structure, realizes riveting of a nut cap by driving the plunger chips to horizontally move through vertical movement of the inclined wedges, is convenient for riveting, is safe and reliable, facilitates the positioning of the workpiece and the nut cap, and can be widely applied to the field of riveting of the end part of the workpiece.

Description

technical field [0001] The invention relates to a riveting die, in particular to a cap riveting die. Background technique [0002] Usually, in the circular riveting process, the riveting head is made into a 360° ring, which is set on the workpiece, and under the vertical pressure of the press, it moves back and forth in one direction to rivet. If some workpieces with complex structures such as: two large ends, small middle, and the riveting position is in the middle workpiece, when riveting, the riveting difficulty will be greatly improved. Especially for the riveting of cylinders, it is more difficult to move riveting in the vertical direction. Contents of the invention [0003] The purpose of the present invention is to provide a cap riveting die, which solves the problem that the existing riveting die moves riveting from top to bottom, the cap at the end of the workpiece is inconvenient to locate, and the riveting is difficult. [0004] The technical solution adopted ...
