A kind of rivet pressing element
Technical field
The utility model relates to a kind of rivet pressing element.
Background technology
Rivet is a kind of in riveted joint, utilizes self deformation or interference to connect by the part of riveting parts.Could implement after the rivet connection need be exerted pressure, whether stress point suitably has a significant impact for the intensity of riveting.Existing riveted joint operation is usually by manually being undertaken by hammering, and operating efficiency is lower and riveting quality is unstable.
Summary of the invention
The utility model purpose is to address the above problem, and a kind of rivet pressing element is provided, and is specifically realized by following technical scheme.
A kind of rivet pressing element, this rivet pressing element comprises lead, upper die and lower die, pressure nail, stage clip and suppresses plate, described patrix is provided with the pilot hole that is slidingly connected with described lead, and this pilot hole middle part is provided with limited block, described lead one end is provided with the cap corresponding with described limited block, and the one end is fixed on described suppressing on the plate, and described compression spring sleeve is located on the described lead, these stage clip two ends respectively with limited block with suppress the plate Elastic Contact and be connected, described pressure is followed closely an end and is fixedlyed connected with patrix.
Described rivet pressing element, further design is: the described plate that suppresses also is provided with the pressure nail hole corresponding with described pressure nail.
Described rivet pressing element, further design is: the middle side part hollow out that described patrix is relative with suppressing plate.
Described rivet pressing element, further design is: described counterdie middle part is provided with and suppresses corresponding the presenting a theatrical performance as the last item on a programme of plate.
The utility model suppresses plate and carries out smooth extruding in the contraction phase of suppressing of spring to being subjected to the riveted plating face by being provided with, and makes the riveted plating face rivet under formation state, has improved riveting quality; By presenting a theatrical performance as the last item on a programme to the location of riveted plating face, make the riveted joint process need not extra location work.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further specified.
This rivet pressing element comprises lead 1, patrix 2, counterdie 3, presses nail 4, stage clip 5 and suppress plate 6.7 is workpiece, and 71 is rivet.Patrix 2 is provided with the pilot hole 21 that is slidingly connected with lead 1, and these pilot hole 21 middle parts are provided with limited block 22, lead 1 one ends are provided with the cap 11 corresponding with limited block 22, the one end is fixed on and suppresses on the plate 6, stage clip 5 is set on the lead 1, these spring 5 two ends respectively with limited block 22 with suppress plate 6 Elastic Contact and be connected, press the fixing company of nail 4 one ends and patrix.Suppress plate 6 and also be provided with the pressure nail hole 61 corresponding with pressing nail.The middle side part hollow out that patrix is relative with suppressing plate.Counterdie 3 middle parts be provided with suppress plate 6 corresponding present a theatrical performance as the last item on a programme 31.
The utility model suppresses plate and carries out smooth extruding in the contraction phase of suppressing of spring to being subjected to the riveted plating face by being provided with, and makes the riveted plating face rivet under formation state, has improved riveting quality; By presenting a theatrical performance as the last item on a programme to the location of riveted plating face, make the riveted joint process need not extra location work.
