Abstract
The invention discloses a part punching and flanging method and relates to the stamping technical field. The part punching and flanging method is implemented through a part punching and flanging die and comprises the following operation steps of step A, placing the part punching and flanging die on a workbench of a press machine and arranging an upper die frame on a pressing rod of the press machine through bolts; step B, placing a sheet metal part on a material returning plate of a lower die frame; step C, starting the press machine to enable the upper die frame to drive a cavity die to descend to punch and flange the sheet metal part; step D, starting the press machine to enable the upper die frame to drive the cavity die to ascend and detaching the sheet metal part. Compared with the prior art, the problem that the existing punching and flanging die is difficult to be stripped can be solved.
Description
Technical field
The present invention relates to stamping technology field, especially a kind of method 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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of part piercing and flanging, to solve the problem of the difficult demoulding of existing extruding tool.
The technical scheme that technical solution problem of the present invention adopts is: a kind of method of part piercing and flanging, use a kind of part extruding tool, 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;
Comprise following operating procedure:
A, described part extruding tool is placed on the workbench of forcing press;
B, sheet metal component is placed on the described stripper of described lower mold holder;
C, starting pressure machine, make described top mold frame drive described die descending to described sheet metal component piercing and flanging;
D, make described top mold frame drive described die up, unload the described sheet metal component of piercing and flanging.
Owing to have employed technique scheme, the present invention 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 invention will be further described:
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.
A kind of method of part piercing and flanging, it is characterized in that: use a kind of part extruding tool as shown in Figure 2, Figure 3 and Figure 4, this part extruding tool 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;
Comprise following operating procedure:
A, part extruding tool is placed on the workbench of forcing press;
B, sheet metal component 13 and sheet metal component 14 are placed on the stripper 8 of lower mold holder 6;
C, starting pressure machine, make top mold frame 1 drive die 3 descending to two pieces sheet metal component piercing and flanging;
D, make top mold frame 1 drive die 3 up, unload sheet metal component 13 and the sheet metal component 14 of piercing and flanging respectively.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.
