Abstract

A group riveting device for clinch nuts comprises a die handle, an upper die holder, an upper die, a female die, an ejection rod, a small guide pillar, a lower die, a low die holder and a stripping screw, wherein the die handle, the upper die holder and the upper die form an upper press die, the ejection rod sleeved with a spring outside is arranged on the female die, and the smaller guide pillar is fixed below the female die and connected with the lower die; the lower die and the lower die holder form a lower press die, the lower die is provided with the stripping screw sleeved with a spring outside, and the upper end of the stripping screw is connected with the female die. The group riveting device for clinch nuts has the advantages of reasonable design and convenience in operation, solves the problem about forming when a plurality of clinch nuts are riveted together and is applicable to batch production of assembly lines. Besides, consumption of energy resources and labor cost can be reduced, a great quantity of imported riveting tools can be substituted, the problems that riveters often need maintenance and riveter heads are easy to damage and the like in conventional riveting method are solved, riveting efficiency and quality are improved greatly, and clinch nuts can be widely applied.

Description

A kind of riveting nut group riveting set
Technical field
The present invention relates to a kind of industrial fastener riveting set, concrete is a kind of riveting nut group riveting set.
Background branch art
Current, domestic industry processing enterprise generally all is to adopt single staking forming technique when riveting nut is riveted.Its shortcoming is singlely to process, and not only production efficiency is low, and clincher tool costliness (needing import mostly), and the stake rapid wear is easily broken; Substantially can not satisfy the requirement that riveted joint is in batches produced.At present, also occur both at home and abroad using mould that riveting nut is implemented group press related data or the report of technology, also do not have standard queries.
Summary of the invention
At the problem of above-mentioned existence, the purpose of this invention is to provide a kind of riveting nut group riveting set.
Technical scheme of the present invention is: a kind of riveting nut group riveting set, comprise die shank, upper bolster, patrix, die, ejector beam, little guide pillar, counterdie, die shoe, material returned screw, and it is characterized in that: die shank, upper bolster and patrix are formed top die; Die is provided with the ejector beam that the outside is with spring, little guide pillar is fixedly arranged under the die, and little guide pillar is connected with counterdie; Counterdie and die shoe connect to form dip mold, and counterdie is provided with the material returned screw that the outside is with spring, and material returned screw upper end links to each other with die.
Described die is provided with some shaped holes, and counterdie is provided with resigning hole, and resigning hole is corresponding with the shaped hole on the die.
Described ejector beam quantity is more than 3.
Described little guide pillar quantity is 2.
Described material returned screw number is more than 2.
Described die can move back and forth under little guide pillar guiding with moving up and down of top die.
Advantage of the present invention: this device is reasonable in design, and is easy and simple to handle; Solve a plurality of riveting nuts and rivet the shaping problem simultaneously, be fit to streamline production in batches; Not only can reduce the energy and cost of labor consumption, and can substitute the import clincher tool in a large number, solve problems such as riveting gun maintenance, rifle head rapid wear in traditional clinching method; Improved riveted joint efficient, riveting quality greatly, riveting nut is used widely.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Now by reference to the accompanying drawings, the present invention is further specified.
As shown in Figure 1, die shank 1, upper bolster 2 and patrix 3 are formed top die; Die 4 is provided with the ejector beam 5 that the outside is with spring, and die fixedly has little guide pillar 6 for 4 times, and little guide pillar 6 is connected with counterdie 7, and die 4 can move back and forth under little guide pillar 6 guiding with moving up and down of top die; Counterdie 7 connects to form dip mold with die shoe 8, and counterdie 7 is provided with the material returned screw 9 that the outside is with spring, and material returned screw 9 upper ends link to each other with die 4.
Wherein, die 4 is provided with some shaped holes, and counterdie 7 is provided with resigning hole, and resigning hole is corresponding with the shaped hole on the die 4.
Described ejector beam 5 quantity are more than 3, and described little guide pillar 6 quantity are 2, and material returned screw 9 quantity are more than 2.
This device can be connected with hydraulic pressure, punching press, pneumatic compression devices, and equipment tonnage is by treating that riveter spare size, shape determine; For preventing from riveting riveting, can regulate by the stopping means on hydraulic pressure, punching press, the pneumatic compression devices.
During work, with riveting nut 101 pass treat riveter spare 102 treat to be positioned over behind the rivet hole in the shaped hole on the die 4, start power-equipment, top die is descending, riveting nut 101 touches the resigning hole on the counterdie 7, the riveting nut distortion, power-equipment touches limited block then, and the riveted joint distortion puts in place, top die is up, ejector beam 5 and material returned screw 9 resilience under spring action treat that riveter spare 102 and die 4 reset simultaneously, finish riveted joint.
