Description

The punching press progressive die that has riveting set

Technical field

The utility model relates to the field of stamping Die Design, relates in particular to a kind of punching press progressive die that has riveting set.

Background technology

On the traditional handicraft; Riveted joint is adopted in the connection of a plurality of metal parts usually, presses, revolves modes such as riveting, all need make the riveted joint special tooling; This process exists that operation is many, complex process, production efficiency is low, manufacturing cost is high problem; Also, therefore influenced the uniformity of quality of item and size, also can cause the generation of operating personnel's personal injury accident simultaneously because die produces irregular deflection and distortion to piece surface.Current, reduce the requirement of manufacturing cost, force whole the integrated requirement that becomes a part as much as possible of a plurality of part combinations more and more urgent, in this case, need to change the technology of riveted joint separately.

Summary of the invention

Deficiency in view of the prior art existence; It is simple in structure that the utility model purpose is to provide; The riveting set that can in common punching press progressive die, install additional; Installed the punching press progressive die of riveting set additional with a pair, the riveted joint process that makes part is accomplished with the appearance and size moulding of part in punch process simultaneously.

For achieving the above object; The utility model adopts following technical scheme: a kind of punching press progressive die that has riveting set; Comprise the punch that is fixedly connected sequentially with upper bolster fixedly backing plate, punch retainer, discharging backing plate, stripper; The die backing plate, the concave template that are fixedly connected sequentially with die shoe; It is characterized in that: also comprise drive link, riveted joint mold insert, lever locating piece, drive link, distance screws, packing ring, spring, wedge, punch, limited post, lever, spring, be provided with a groove in described punch retainer, discharging backing plate, the stripper, described punch inserts in the groove; Be set with packing ring, spring, distance screws through being arranged in the upper bolster are fixed, and described wedge is fixed on the side of punch retainer through soket head cap screw; The described lever locating piece that studs with lever is fixed in the groove of die shoe below setting; Described concave template, die backing plate, die shoe respectively are provided with groove on lever two ends correspondence position; Limited post and the drive link that links together through soket head cap screw is housed in the one end groove; The riveted joint mold insert that links together through soket head cap screw is housed in the other end groove and is with on the drive link of spring, described lever two ends are set to sphere, and the center is provided with hemispherical projections.

The advantage and the good effect of the utility model are: only need to install riveting set additional at the punching press progressive die; Punching press profile and riveted joint completion simultaneously be can realize, when adopting the die production of this new structure, a mold, the logical punch press of a Daepori only need be utilized; An operative employee can accomplish; Greatly reduce the input of mould, equipment and human resources, guaranteed part quality simultaneously, ensured operating personnel's personal safety.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in the figure; The punching press progressive die that has riveting set; Comprise the punch that is fixedly connected sequentially with upper bolster 1 fixedly backing plate 2, punch retainer 3, discharging backing plate 4, stripper 5; The die backing plate 7, the concave template 6 that are fixedly connected sequentially with die shoe 8; Also comprise drive link 63, riveted joint mold insert 64, lever locating piece 65, drive link 66, distance screws 67, packing ring 68, spring 69, wedge 70, punch 73, limited post 74, lever 76, spring 78, be provided with a groove in punch retainer 3, discharging backing plate 4, the stripper 5, punch 73 inserts in the groove; Through be arranged in the upper bolster 1 to be set with packing ring 68, spring 69, distance screws 67 fixing, wedge 70 is fixed on the side of punch retainer 3 through soket head cap screw; The lever locating piece 65 that studs with lever 76 is fixed in the groove of die shoe 8 belows setting; Concave template 6, die backing plate 7, die shoe 8 respectively are provided with groove on lever 76 two ends correspondence positions; The limited post 74 and drive link 66 that link together through soket head cap screw are housed in the one end groove; The riveted joint mold insert that links together through soket head cap screw 64 is housed in the one end groove and is with on the drive link 63 of spring 78, lever 76 two ends are set to sphere, and the center is provided with hemispherical projections 761; The hemispherical projections 761 of corresponding lever 76, lever locating piece 65 is provided with hemispherical groove.The upper end of punch 73 is the inclined-plane, and the front end of the wedge 70 that is mated also is designed to the inclined-plane, and adjustment wedge 70 can be adjusted the length that punch 73 leans out punch retainer 3.

The course of work is following: before the work, upper bolster 1 is fastened on the slider of punch, and die shoe 8 is fastened on the following table of punch press.

Start punch press; Upper bolster 1 is along with slider of punch moves down; Promote stripper 5 and at first contact, strip is contacted with concave template, further move down the first-class high sleeve spring compression of back mould with strip; The space is reduced gradually; Punch 73 also leant out stripper 4 gradually and pressed to drive link 66 this moment, and slider of punch continues to move down, thereby the end that punch 73 is pushed down drive link 66 and together pushed away lever 76 moves downward in lever locating piece 65 other end of lever 76 is moved upward.The end that lever 76 upwarps is pushing away drive link 63 and is moving upward; Promoting riveted joint mold insert 64 makes punching parts crooked gradually; Riveting portion is upwards gone on the top; Thereby make punching parts 77 riveted joint flange move closer to and get in the riveted holes on it, at this moment, the spring 78 that is enclosed within on the drive link 63 is gradually reduced.When slider of punch continues to be moved down into bottom dead centre; Punch 73 is being pressed drive link 66 pushing away lever 76 1 ends and in lever locating piece 65, is being moved downward and stop; Lever 76 other ends withstand drive link 63 and are pushing away crooked riveted joint mold insert 64 and move upward and also stop; This moment, punching parts 77 riveted joint flange got in the riveted holes fully, were riveted on together.

Afterwards, slider of punch drives upper bolster 1 to begin to move up, and under the recoil of spring effect on the sleeve such as height such as grade 18, separates gradually between stripper backing plate 4 and the punch retainer 3; Punch 73 also bounces back simultaneously gradually; Spring 78 beginning resiliences drive drive link 63 and move downward with riveted joint mold insert 64, and an end of pressing lever 76 to upwarp moves downward; Make moving upward of lever 76 other ends, drive link 66 is moved upward.Upper bolster 1 continues to move up, and the recovering clearance between discharging backing plate 4 and the punch retainer 3 is to original state, at this moment; Punch 73 is fully retracted in the stripper 5; Spring 78 springs back to original state, drive link 63 stop motions, and lever 76, drive link 66 all return to original state.Upper bolster 1 continues to move up, and the guide pin on the mould holds up strip, and strip and concave template were opened in 6 minutes, on when moving on to top dead-centre, stripper 5 breaks away from strip, such riveting work is accomplished.
