Description
Technical field
The utility model relates to diel manufacturing technology field, especially a kind of mould for automobile metal plate work piercing and flanging.
Background technology
The pattern of tradition piercing and flanging is that the downward pressure that forcing press produces is realized part hole flanging by mould action on sheet metal component, and this piercing and flanging generally turns over downwards from part upper surface.Have the symmetrical sheet metal component of a kind of two pieces as shown in Figure 1, the hole of flange to be punched be positioned at the bottom surface of part and the flange in hole upwards; Use a kind of extruding tool to carry out piercing and flanging to this sheet metal component at present.This extruding tool comprises the lower mold holder being provided with punch and the top mold frame being provided with die.In use there are the following problems for this extruding tool: because punch is located at the below of die, when completing the piercing and flanging of sheet metal component, the demoulding is more difficult, sheet metal component can bind on die up with forcing press, workman is needed to beat with gavel or move could realize the demoulding with hand, not only time-consuming, also there is potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of part extruding tool of the easy demoulding, to solve the problem of the difficult demoulding of existing extruding tool.
The technical scheme that the utility model technical solution problem adopts is: this part extruding tool comprises the top mold frame of the lower mold holder that the is provided with multiple punch die corresponding with being provided with multiple and described punch, described die is provided with the stamping die central through hole of described punch, described die is provided with material returned pushing block in stamping die central through hole, and described material returned pushing block is contained in bottom described lower mold holder by stage clip; Described lower mold holder is equipped with the stripper driven by lift cylinder; When described punch and described die are matched moulds state, described punch stretches into the stamping die central through hole of described die and described material returned pushing block abuts against.
In above-mentioned part extruding tool technical scheme, technical scheme can also be more specifically: on described stripper, push rod is housed, and described push rod is connected with die pad through described lower mold holder, and described die pad is connected with described lift cylinder.
Further: on described stripper, to be provided with the pilot hole installing described punch, the height of described punch is higher than the height of described stripper.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect: 1, owing to being provided with stamping die central through hole at die and by stage clip, material returned pushing block being housed in its stamping die central through hole, the stripper driven by lift cylinder lower mold holder is equipped with, when completing the piercing and flanging of sheet metal component, when top mold frame is up, material returned pushing block in die stamping die central through hole produces a downward thrust under the effect of stage clip, is evaded sheet metal component from die downwards by the hole of flange; Sheet metal component is upwards evaded from punch by stripper under lift cylinder drives, thus realizes the fast demoulding of sheet metal component; 2, time saving and energy saving, eliminate safe hidden trouble.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Be illustrated in figure 1 the symmetrical sheet metal component 13 of two pieces and sheet metal component 14, all have the hole of a flange to be punched in the bottom surface of two pieces sheet metal component.
Part extruding tool as shown in Figure 2, Figure 3 and Figure 4 comprises the lower mold holder that is provided with two punch 5 and is provided with the top mold frame 1 of two dies 3 corresponding with punch 5, and top mold frame 1 is socket-connected by guide pin bushing and lower mold holder; Two punch 5 are contained on lower mold holder by bolt, and feet 7, two pieces of feets 7 that lower mold holder has lower bolster 6 and is contained in lower bolster bottom surface are contained in the two ends of lower bolster bottom surface respectively; The lower bolster 6 of lower mold holder is equipped with the stripper 9 driven by lift cylinder 12; Stripper 9 has the pilot hole that two install punch 5, the height of punch 5 is higher than the height of stripper 9, stripper 9 is equipped with push rod 10 by screw thread, and push rod 10 is threaded with die pad 8 through the lower bolster 6 of lower mold holder, and die pad 8 is connected with the piston rod of lift cylinder 12; Because the height of punch 5 is higher than the height of stripper 9, when sheet metal component upwards pushes away by stripper 9 under lift cylinder 12 drives, stripper 9 is by up under the guiding that is installed on punch 5 in pilot hole; Top mold frame 1 is positioned at above lower mold holder, die 3 is contained in top mold frame 1 by connecting plate, and die 3 has the stamping die central through hole of punch 5, at the stamping die central through hole of die 3 built with material returned pushing block 4, material returned pushing block 4 is connected with one end of stage clip 2, and the other end of stage clip 2 is contained in bottom lower mold holder 1; When punch 5 is matched moulds state with die 3, the end face of stamping die central through hole and material returned pushing block 4 lower end that punch 5 stretches into die 3 abuts against.
During work, the top mold frame 1 of part extruding tool is contained on the workbench of forcing press, two pieces sheet metal component 10 and sheet metal component 11 are contained on the stripper 8 of lower mold holder, starting pressure machine top mold frame 1 is driven die 3 is descending carries out piercing and flanging to two pieces sheet metal component 10 and sheet metal component 11; After completing piercing and flanging, starting pressure machine makes top mold frame 1 drive die 3 up, and now, the material returned pushing block 4 in die 3 stamping die central through hole produces a downward thrust under the effect of stage clip 2, evades from die 3 by the hole of flange downwards by sheet metal component; Sheet metal component is upwards evaded from punch 5 by stripper 9 under lift cylinder 12 drives, thus realizes the fast demoulding of sheet metal component, time saving and energy saving and eliminate safe hidden trouble.
