Riveting side pushes away the shovel sword and promotes horizontal side and push away slider lateral shifting on the antifriction plate, horizontal side pushes away the slider and moves ahead at the side and pushes away the limiting plate lower extreme, horizontal side pushes away the slider extrusion horizontal side and pushes away spring and the shrink of lower mould rivet spring, horizontal side pushes away the slider and promotes lower mould rivet drift seat and shift up, it is ejecting with lower mould rivet drift, hold up and wait to dash to rivet the rivet and go upward, the rivet pushes up the material rocking arm outwards to open the compression and hold up the material rocking arm spring both sides, it is downthehole also to insert the rivet to rivet simultaneously towards guide nail, guarantee that the rivet embolias the hole of product material area perpendicularly, rivet drift and lower mould rivet drift extrude the rivet simultaneously down until going up the mould, let the weak link variant back seat in rivet middle part, thereby realize pressing the rivet on the product material area.

At the same time: when the pay-off spiller moves down along with second downshifting of public splint, the pay-off spiller moves down, the minor face effect of right trapezoid cutter body with on the vertical piece of trapezoidal in the pay-off frame, the pay-off frame is under the effect of pay-off frame extrusion force, three back down of elastic component, the pay-off frame moves back together, it receives the extrusion at rivet back to hang the material tooth this moment, hang the right angle trapezoidal string sword inclined plane of material tooth and compress downwards and slide backward, when the punch press arrives the closed condition of mould down, it also slides to the terminal rivet position below of vibration dish to hang the material tooth, the right angle trapezoidal string sword of hanging the material tooth is hung into rivet bottom hole, realize hanging the material, the punch press finishes down.

The punch press ascends, the first upper die device and the feeding die base gradually ascend to drive the feeding shovel blade and the riveting side pushing shovel blade, the upper die riveting assembly and the anti-withdrawing needle ascend, the riveting side pushing shovel blade, the transverse side pushing spring and the lower die rivet spring reset to generate power, the lower die side pushing slide block and the rivet upper jacking device retreat and return, the power generated by the resetting of the material supporting rocker arm springs at the two sides pushes the material supporting rocker arm to return, meanwhile, the feeding shovel blade also gradually moves upwards, the elastic part III of the feeding frame pushes the feeding frame and the hanging teeth and drives one rivet to reset and move forwards, the side surface of the rivet extrudes two rivets to lock the steel balls to retreat, the rivets slide out of the vibration disc track and are brought forwards into the track to be punched and riveted until the mould is opened, the rivets push the feeding frame and the hanging teeth to completely reset in the elastic part III of the feeding frame, thereby realizing a complete material supplementing action, and forming a complete in-mold automatic feeding and automatic riveting process.

The utility model provides an automatic punching and riveting mechanism and full-automatic punching and riveting equipment of rivet, this mechanism can realize full-automatic rivet material loading and automatic punching and riveting, and the rivet realizes full automated control from the material loading to punching and riveting process, can satisfy in the mould automatic even dash take the full automatization technology of riveting, has reduced the degree of dependence to the manual work, has reduced manufacturing cost, has promoted production efficiency, and the uniformity of punching and riveting the product is good, has improved the performance of product. The rivet can be automatically fed into a designated position by the feeding mechanism, one rivet is accurately transferred each time, the discharging speed is uniform, automatic feeding is realized, and accurate feeding can be realized; the full-automatic punching and riveting can be performed on the loaded rivet in the die through the punching and riveting mechanism, and the product after punching and riveting is good in stability and stable in riveting; through the matched arrangement of the riveting side-push shovel knife and the side-push transverse moving assembly and the matched arrangement of the side-push transverse moving assembly and the rivet jacking device, the upward movement and jacking of the rivet can be automatically controlled, the rivet is automatically inserted into a region to be riveted on a material belt, and through the matched arrangement of the rivet jacking device, the upper die riveting punching assembly and the material supporting assembly, the automatic punching riveting can be realized, the product positioning is accurate, and the punching riveting effect is good; through holding up the setting of material subassembly, can treating to dash to rivet the subassembly and carry out the centre gripping location, avoid dashing to rivet in-process rivet lateral shifting, dash to rivet the location more accurate, promoted the riveting effect of product. The utility model has the advantages of simple overall structure, can realize that full-automatic accurate pay-off, mould are towards riveting, easily industrialization.
