Preferably, described counterdie comprises base plate, be fixed on the supporting plate on the base plate, be positioned at the fixed head on the supporting plate, be provided with one group of groove of placing riveted joint on the fixed head, riveted joint can move in groove, and groove extends to supporting piece cover place, described recoil press spring one side pressure is on riveted joint, and the other end is pressed on the sidewall of supporting piece cover.
For making things convenient for the workpiece location, also be provided with the backup plate for the workpiece location on the described fixed head.
For making things convenient for recoil press spring to install, be provided with circular hole on the described riveted joint, an end of recoil press spring places in the circular hole.
For making things convenient for workpiece to fix, described patrix comprises punch shank plate, add-in card, upper mould fixed plate, and the three superposes successively and is bolted on together; Also comprise the die shank that is arranged on the punch shank plate and be fixed on the casting die piece that is used for fixation workpiece on the patrix.
Preferably, be provided with the flexible spring of adjusting casting die piece between described casting die piece and die shank.
Beneficial effect of the present invention: describedly tiltedly carve the horizontal movement that the vertical motion that will tiltedly carve changes into riveted joint, so that this mould can be riveted the workpiece optional position, described riveted joint riveted joint end is encircled into circle, makes things convenient for the riveting of a cylindrical sleeve bag on another cylindrical entity.Described groove makes things convenient for laying of riveted joint, effectively controls simultaneously the direction of motion of riveted joint, and simple in structure, design is convenient.Described circular hole makes things convenient for the installation of recoil press spring.The backup plate structure makes things convenient for the workpiece location, improves the riveted joint qualification rate.Described upper molding piece makes things convenient for workpiece to fix, and spring structure makes things convenient for picking and placeing of workpiece.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
