Abstract
The invention discloses a punching nut riveting die which comprises an upper die rack (2), a lower die rack (9), an upper die fixing plate (3) and a lower die fixing plate (8), wherein a part positioning pin (7) is arranged on the lower die fixing plate (8); a nut positioning piece (1) with a hole is arranged on the upper die fixing plate (3); a permanent magnet (4) is arranged in the hole of the nut positioning piece (1); the lower die fixing plate (8) is provided with a concave die (5); and a concave die embedding piece (6) is embedded in the concave die (5). By adopting the structure, the invention utilizes the punching nut as the punch head to perform primary punching and riveting, thereby not only ensuring the riveting strength, but also enhancing the working efficiency.
Description
Technical field
The present invention relates to a kind of machine die structure, especially relate to a kind of punching nut riveting die.
Background technology
At present, for car range, the particularly sheet stamping member manufacturing of German car, because some stamping parts assembling nuts can not adopt solder technology, as the manufacturing of engine hood panel assembly, gear shifting handle assembly and the bogie bracket assembly part of car, the assembling nut of these stamping parts has to adopt riveting technology production.Traditional production technology is punching and riveted joint, the characteristics of this mode of production are punchings on stamping parts earlier, again nut being put into the hole rivets, promptly need two procedures, two lathes, two employees produce, and not only waste lathe, also reduced production efficiency, and the situation that riveting nut also can occur leaking when producing in enormous quantities.
Summary of the invention
The purpose of this invention is to provide a kind of can a punching press punching nut riveting die of riveted joint.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises top mold frame, following mould bases, upper mould fixed plate and counterdie fixed head, the counterdie fixed head is provided with the part alignment pin, described upper mould fixed plate is provided with nut retainer member with holes, is provided with permanent magnet in the hole of nut retainer member; The counterdie fixed head is provided with a die, is installed with a die mold insert in the die.
The said structure that the present invention adopts utilizes punching nut to work as a punching press of drift riveted joint, not only guarantees riveting intensity, and has improved operating efficiency.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
The specific embodiment
By accompanying drawing as can be known, this punching nut riveting die comprises top mold frame 2, following mould bases 9, and upper mould fixed plate 3 and counterdie fixed head 8, counterdie fixed head 8 are provided with part alignment pin 7, described upper mould fixed plate 3 is provided with nut retainer member with holes 1, is provided with permanent magnet 4 in the hole of nut retainer member 1; Counterdie fixed head 8 is provided with a die 5, is installed with a die mold insert 6 in the die 5.The material of punching nut is No. 45 steel, and cold-drawn is processed into behind the section bar segmentation again and is made nut, and the hardness of nut reaches the HRC26-28 degree.At first stamping parts is placed on the counterdie fixed head by part alignment pin location, permanent magnet is adsorbed on nut on the nut retainer member, vibration comes off and weighs mould wounded when preventing the nut punching press, utilize these hardness characteristics of nut self to make punch, and unique die mold insert pierces through the stamping parts surface and the stamping parts material is pressed in the lateral groove of punching nut, thereby nut and stamping parts plate are riveted tightly.Nut retainer member can play the effect of screening nut in the location.The die mold insert plays the effect of concavo-convex mould when nut is riveted, not only punching but also rivet, and the purpose of using mold insert is convenient for maintaining also.
