Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, constant force pressure riveting device is for being pressed into stamping parts by rivet, and it includes upper mold portion, lower mold portion, peace
Being loaded on the portion that presses 2 in described upper bolster 1-1 and the buoyant portion 4 being installed in described lower mold portion, described upper mold portion includes
Die holder 1-1, described in press the constant pressure cylinder 2-1 that portion 2 includes being installed in described upper bolster 1-1, under described lower mold portion includes
Die holder 3-2, the lower bolster 3-1 being fixed on described die shoe 3-2, be arranged on described die shoe 3-2 and lower bolster 3-1 floating
Material assembly.
Described upper mold portion also include the limit for height post 1-2 being connected on described upper bolster 1-1 lower surface, be fixedly connected on described
Limit for height post 1-2 lower end and the first fixed plate 1-3 that the cylinder body of constant pressure cylinder 2-1 is pushed against on upper bolster 1-1, fixing connection
The second fixed plate 1-4 in described first fixed plate 1-3 lower end, the pressure being connected on the piston rod of described constant pressure cylinder 2-1
Riveting dowel steel 2-2, be connected to described in press dowel steel 2-2 lower end the drift 2-3 that presses, described in press dowel steel 2-2 and described
The drift 2-3 that presses runs through described first fixed plate 1-3 and described second fixed plate 1-4, described first fixed plate 1-3 and described
The middle part hollow out of two fixed plates 1-4 forms frame-type.The height of the constant pressure cylinder 2-1 height slightly larger than limit for height post 1-2, difference in height
At 1 ~ 2cm.
