Abstract
The invention discloses a riveting process for riveting a nut on a lateral brattice. The riveting process specifically comprises the following steps: a riveting nut (2) is arranged on a positioning nail (5) of a lower mould (1); the lateral brattice (3) is prepunched at a position to be riveted and then is sleeved on the positioning nail (5) for pressing; when an upper mould (4) is contacted with the lateral brattice (3), a pair of cutting edges for blanking are formed by the inner wall of the upper mould (4) and the peripheral edge of the riveting nut (2); and after blanking, the upper mould (4) moves downwards to press the peripheral material of the riveting nut (2) into a peripheral groove of the riveting nut (2), therefore, the riveting nut (2) is riveted on the lateral brattice (3). Due to the adoption of the process, the invention solves the problems of huge investment in apparatuses, high shared cost and the like which are caused by the adoption of overseas riveting process, reduces the cost of apparatus investment and can ensure the accuracy of the riveting position.
Description
Technical field
The present invention relates to a kind of riveting process, especially relate to a kind of riveting process that is used for riveting nut on lateral brattice.
Background technology
At present, connecting process for gusset plate and other part, mostly adopt field riveting nut on the gusset plate earlier, connect with other part by nut again, particularly very wide in the application of auto parts machinery field, because the big part of amount is many, manual rivet can't be competent at, adopt the riveted joint mould to be used for field riveting nut on the gusset plate, improved efficient.Be to adopt autoloader that nut is delivered in the riveted joint mould for this riveted joint abroad, because of adopting the atresia riveted joint, there is requirement the position of riveted joint, adopts the manipulator location abroad and grasps workpiece, locatees the precision that guarantees to rivet the position with manipulator when riveted joint.Because of adopting automatic feeding and manipulator location and holding workpiece, the investment of whole this riveting equipment will be very huge, owing to the problem of output, cause the problem of the very high aspect of cost sharing.
Summary of the invention
The purpose of this invention is to provide the riveting process that is used for riveting nut on lateral brattice that a kind of technology is simple, the equipment needed thereby cost of investment is low.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises on the locating pin that at first riveting nut is placed into counterdie locatees; The gusset plate in the hole that can be inserted in locating pin of the position that will rivet punching out in advance, is located the gusset sleeve-board on locating pin, suppress then; When patrix is descending when touching the gusset plate, the periphery of patrix inwall and riveting nut forms a pair of cutting edge, and stamping-out is carried out in the position that the offside coaming plate will be riveted; After stamping-out finished, patrix continued descending, and the periphery material of riveting nut is pressed in the groove of riveting nut periphery, and after patrix compressed the riveting nut periphery, patrix was with up, and riveting nut is riveted on above the gusset plate; The gusset plate is taken off from locating pin.
The above-mentioned technology that the present invention adopts, it is huge to have solved the equipment investment aspect input that adopts external riveting process to bring, and the problem of the very high aspect of cost sharing reduces equipment investment cost, can guarantee to rivet the precision of position.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as the structural representation of riveted joint mould required for the present invention
The specific embodiment
As shown in drawings, the required riveted joint mould of technology of the present invention comprise can the knee-action stroke patrix 4 and counterdie 1, the lower edge of patrix 4 is the cutting edge at band oblique angle, counterdie 1 tightens locating pin 5 is installed.Specific embodiment of the present invention is: riveting nut 2 is placed on the locating pin 5 of counterdie 1, location as riveting nut 2, with gusset plate 3 in the hole that can be inserted in locating pin 5 of the position that will rivet punching out in advance, gusset plate 3 is enclosed within on the locating pin 5 as the location, suppress then, when patrix 4 is descending when touching gusset plate 3, the periphery of the inwall of patrix 4 and riveting nut 2 forms a pair of cutting edge, carry out stamping-out on the position that the offside coaming plate will be riveted, after stamping-out finishes, patrix 4 continues descending, the periphery material of riveting nut 2 is pressed in the groove of periphery of riveting nut 2, after last patrix 4 compressed riveting nut 2 peripheries, patrix 4 was with up, riveting nut 2 just has been riveted on above the gusset plate 3 then, at last gusset plate 3 is taken off from locating pin 5.The present invention is with the described scope of soverlay technique scheme; and the various modification of claim scope and equivalence variation; under the prerequisite that does not depart from technical solution of the present invention, any modification or improvement that those skilled in the art that the present invention did are realized easily all belong to the present invention's scope required for protection.
Claims (1)
1. riveting process that is used for riveting nut on lateral brattice is characterized in that:
