Preferably, the rivet head unit has an inclination of 4 ° ± 0.5 ° to the vertical.
Preferably, a torsion buffer opening is formed in the outer side of the joint of the supporting and positioning shaft and the pressing plate.
The riveting device has the advantages that two riveting head units are arranged at the lower end of the riveting head main body, so that two riveting operations can be realized at one time, the pressing plates are arranged at the front ends of the two supporting and positioning shafts, the pressing springs are arranged between the upper surfaces of the pressing plates and the supporting and positioning shafts, the front ends of the supporting and positioning shafts are in sliding connection with the pressing plates, and the riveting pressing heads penetrate through the pressing plates, so that the pressing plates can synchronously press the surfaces of riveting pieces during riveting, a pressing force is provided, the stability of the riveting pieces can be ensured when riveting impact is applied to riveting force, the riveting pieces cannot be pushed by riveting force to generate transverse or other unexpected twisting, and the quality of the riveting pieces is ensured.
And because the inclination angle of the riveting head unit and the vertical line is 4 degrees +/-0.5 degrees, the angle is suitable for most riveting bulges, when the riveting bulges are riveted and pressed, the pressure of the riveting head can be maximally applied, the full utilization of riveting power is ensured, and the riveting quality and efficiency can be ensured.
The compression spring can conveniently replace springs with different pressing forces so as to meet the pressing requirements of different riveting pieces. Meanwhile, the twisting buffer port is arranged on the outer side of the joint of the supporting and positioning shaft and the pressing plate, so that the small displacement of the supporting and positioning shaft can be caused by the twisting force generated when the riveting joint unit is riveted and pressed, at the moment, the small deformation can be generated due to the existence of the twisting buffer port, the small displacement can be eliminated, the impact generated by the next small displacement can not be transmitted to the pressing plate, the stability of the pressing force of the pressing plate is ensured, the pressing quality is ensured, and the riveting quality is further ensured.

Detailed Description
The present invention will be further described with reference to the following examples.
Fig. 1-4 show an embodiment of a riveting head 1 of the present invention, and as can be seen in fig. 1, the riveting head 1 includes a riveting head main body 10601, a riveting head unit 10602 is disposed at a lower end of the riveting head main body 10601, a riveting pressure head 10603 is disposed at a front end of the riveting head unit 10602, support positioning shafts 10606 are disposed at two sides of the lower end of the riveting head main body 10601, pressure plates 10605 are disposed at front ends of the two support positioning shafts 10606, a pressure spring 10604 is disposed between an upper surface of each pressure plate 10605 and each support positioning shaft 10606, a front end of each support positioning shaft 10606 is slidably connected to the pressure plate 10605, and the riveting pressure head 10603 penetrates through the pressure plate 10605; the number of the rivet joint units 10602 provided at the lower end of the rivet joint body 10601 is two.
Because the lower end of the rivet joint main body 10601 is provided with two rivet joint units 10602, two riveting operations can be realized at one time, and because the front ends of the two supporting and positioning shafts 10606 are provided with the pressing plates 10605, the pressing springs 10604 are arranged between the upper surfaces of the pressing plates 10605 and the supporting and positioning shafts 10606, the front ends of the supporting and positioning shafts 10606 are in sliding connection with the pressing plates 10605, and the riveting press head 10603 penetrates through the pressing plates 10605, the pressing plates 10605 can synchronously press the surfaces of the riveting pieces during riveting to provide pressing force, the riveting force can also ensure the stability of the riveting pieces during riveting impact, the riveting force can not push the riveting pieces to generate transverse or other unexpected twisting, and the quality of the riveting pieces is ensured.
