Referring to fig. 2, 3 and 4, a riveting assembly of the utility model is shown, comprising an backer 10, a support seat 20 and a punch 30;
a first step surface 21 and a second step surface 22 are formed on one side wall of the support seat 20;
the first step surface 21 is provided with a mounting groove 211, the mounting groove 211 longitudinally penetrates through the first step surface 21, and the backer 10 is mounted in the mounting groove 211;
the backrest 10 comprises a mounting end 11 and a stress end 12, the end surface of the mounting end 11 is flush with the top end of the first step surface 21, and the stress end 12 axially extends from the bottom end of the first step surface 21 and is opposite to the second step surface 22;
the second step surface 22 is provided with a mounting hole 221, the punch 30 is mounted in the mounting hole 221, and the punch 30 is arranged opposite to the stress end 12;
the backer 10 is formed in an i-shape.
In the embodiment of the utility model, the working principle of the backer 10 can be simplified into a cantilever beam, and the maximum deformation deflection at the riveting point can be calculated by the following formula:
wherein, ω ismaxThe maximum deformation deflection at the riveting point of the backer 10 is shown as F, the stamping force of the punch 30 during riveting is shown as l, the length of the backer 10 is shown as E, the elastic modulus of the backer 10 is shown as E, the section inertia distance of the backer 10 is shown as I, and the section inertia distance I is positively correlated with the sectional area of the backer 10.
It can be derived from the above formula that in order to reduce the maximum deformation deflection at the riveting point, the improvement can be made by both increasing the sectional area of the backer 10 and changing the material of the backer 10. In the embodiment of the utility model, the shape of the backer 10 is changed from the T shape adopted in the prior art into the I shape, so that the sectional area of the backer 10 is increased, and therefore, under the condition that the length and the punching force of the backer 10 are not changed, the deformation deflection at the riveting point can be reduced, the rigidity of the backer 10 is improved, the backer 10 is not easy to break, the service life of the backer 10 is prolonged, and the process cost is reduced.
Referring to fig. 2 and 3, preferably, the backer 10 is fixed to the support base 20 by a sling.

Referring to fig. 6 and 7, the force bearing point of the force bearing end 12 is preferably concavely formed into a receiving groove 14. Understandably, when the stress point is a plane, the resistance of the material flowing to the periphery is large in the riveting process, and further a large riveting force is generated, and the process parameter range is possibly exceeded, so that the backer 10 and the supporting seat 20 are damaged, therefore, the stress point is arranged into the accommodating groove 14 with the groove structure, an accommodating cavity and a space are provided for the flowing of the material, the riveting force is reduced, the service lives of the backer 10 and the supporting seat 20 are prolonged, meanwhile, the lock catch is easier to form, and the riveting quality is improved.
Referring to fig. 6 and 7, the mounting end 11 is preferably provided with a positioning groove 15. Understandably, since the backer 10 is formed in an i-shape, there may occur an improper installation caused by an inverse installation during installation, thereby requiring error correction, wasting process time, and possibly even causing damage to riveting equipment. After the positioning groove 15 is formed in the mounting end 11, positioning and mounting can be performed quickly and accurately during mounting, the situation of wrong mounting is not prone to occurring, the process time is saved, and possible equipment damage is avoided.
Preferably, the material of the backer 10 is alloy steel 56 HRC. Understandably, the effect of increasing rigidity and reducing deformation disturbance degree can be achieved by improving the material of the backer 10, and the elastic modulus of the alloy steel adopted in the embodiment of the utility model is 230GPa, which is higher than that of the alloy steel with the elastic modulus of 206GPa adopted in the prior art, so that the effect of increasing rigidity and reducing deformation disturbance degree can be achieved; in addition, the surface treatment of the backer 10 can further improve the surface hardness and strength of the backer 10, achieve better technical effects, and make the backer less prone to fracture. This is a common technical means in the art and will not be described in detail.
Preferably, the supporting base 20 is an integral part. Understandably, the support seat 20 manufactured by integral molding has higher strength than the assembly piece, and thus, is beneficial to prolonging the service life of the support seat 20.
Referring to fig. 8, the riveting apparatus provided by the present invention is shown, including the riveting assembly in the above embodiment, and further including an operating machine 20, where the riveting assembly is installed on the operating machine 20. Because the riveting component in the embodiment is adopted by the riveting equipment, at least all the beneficial effects brought by the technical scheme of the embodiment are achieved, and the detailed description is omitted.
