Nail making combined die for hobnail core of blind rivet

Abstract

The invention discloses a nail making combined die for a hobnail core of a blind rivet. The nail making combined die comprises a main die, a punch and a shearing mechanism, wherein the main die comprises a movable die, a static die and a main die drive, die cavities are formed in the movable die and the static die correspondingly, and the main die drive is connected with the movable die and drivesthe movable die and the static die to be opened and closed; the punch is arranged on one side of the main die and provided with a nail head forming cavity used for forming the head of the nail core;and the shearing mechanism is arranged between the main die and the punch and comprises a upper knife, a lower knife and a shearing drive, and the shearing drive dirves the upper knife and the lower knife to cut off the nail core from a steel wire and form a flat head nail tip. The nail making combined die for the hobnail core of the blind rivet can produce flat head nail cores, is in no contact with hands, no burr, no waste production, energy-saving and environment-friendly, improves the quality and output of rivets, reduces die loss, and is low in noise in the machining process and good in environmental protection effect.

Description

technical field [0001] The invention belongs to the production technology of rivets, in particular to a combined nail-making mold for flat-head nail cores of blind rivets. Background technique [0002] Blind rivets are widely used in automobiles, motor vehicles, electrical cabinets and other fields. At present, the nail points of all blind rivet mandrels are mostly four-pointed or two-edged. Such nail points are likely to cause safety accidents, and flashes and burrs on the nail points are easy to fall off and affect the normal operation of electrical appliances. Contents of the invention [0003] The object of the present invention is to provide a kind of blind rivet flat-head nail mandrel making combination mold, which is used for producing the flat-head nail mandrel of blind rivets, and can improve the automation degree of rivet processing and the quality of rivets, to solve the problem of the prior art. The above-mentioned problems existing in core rivets. [0004] F...

AI Technical Summary

Problems solved by technology

At present, the nail tip of all blind rivet cores is mostly four-pointed or two-edged. This kind of nail tip is likely to cause safety accidents, and the flash and burrs on the nail tip are easy to fall off and affect the normal operation of electrical appliances.
