Abstract
The invention discloses a stamping hole flanging device, and relates to the technical field of stamping die manufacturing. The stamping hole flanging device comprises a plurality of hole flanging female dies and a plurality of hole flanging male dies, wherein the hole flanging female dies are arranged on an upper die, and the hole flanging male dies corresponding to the hole flanging female dies respectively are arranged on a lower die. A plurality of seesaws are arranged on the lower die, and each seesaw is hinged to the lower die through a center shaft. One end of each seesaw is provided with a driving rod which is provided with a pushing rod and a guiding rod connected with the pushing rod, and the other end of each seesaw is provided with a pressing rod. When the upper die and the lower die are in a die assembling state, the hole flanging male dies are connected with the hole flanging female dies in an abutting mode. The guiding rods penetrate through the hole flanging male dies and the hole flanging female dies. The lower die is provided with guiding sleeves which are used for supporting the driving rods and lifting the pressing rods respectively. Compared with the prior art, the stamping hole flanging device has the advantages that the edge-folding and stretching processes on one face of a sheet metal part and the hole flanging process on the other face of the sheet metal part can be carried out at the same time through one-time die assembling, and working efficiency is improved.
Description
Technical field
The present invention relates to diel manufacturing technology field, especially a kind of punching press hole flanging dress for automobile metal plate work
Put.
Background technology
At present, the downward pressure that forcing press is substantially directly produced by the pattern of machinery industry tradition hole flanging by board
It is delivered on the part treating hole flanging, and part hole flanging is realized on sheet metal component by mould action, this hole flanging is usually from zero
Part upper table faces down and turns over；If realizing from piece surface flanging upward hole, sheet metal component must necessarily be placed on the mould of floating, hole flanging
Punch is fixed on die shoe, and under the downward pressure effect of forcing press, sheet metal component moves downwardly together with mould floating part, turns over
Hole punch relative upward movement acting on finally realizes hole flanging operation on sheet metal component；And if sheet metal component upper surface need to be drawn
Prolong, flanging, etc. multiple operation operation, this sheet metal component lower surface also needs to carry out flanging upward hole operation simultaneously, and traditional Sheet Metal Forming Technology is just
And cannot need to carry out secondary die-filling by once die-filling realizing, mould also will be designed to two sets simultaneously, so, no
Only die cost improves, and production efficiency is greatly reduced.
Content of the invention
It is an object of the invention to provide a kind of punching press hole-flanging device, this punching press hole-flanging device is once die-filling can be completed simultaneously
The drawing of sheet metal component one side, flanging operation, the hole flanging operation of another side.
In order to solve the above problems, the technical solution used in the present invention is：This punching press hole-flanging device includes being located at mould
Multiple hole flanging dies and be located at multiple Burring Punchs corresponding with described hole flanging die respectively of lower mould, described lower mould sets
There are multiple seesaws, each described seesaw is all hinged with described lower mould by central shaft；It is provided with drive rod in one end of described seesaw,
Described drive rod has the guide rod being located at top and the push rod being connected with described guide rod；It is provided with pressure in the other end of described seesaw
Bar；When described upper mould and the state that described lower mould is in matched moulds, described Burring Punch is abutted against with described hole flanging die；Described push away
Bar sequentially passes through described Burring Punch and described hole flanging die.
In above-mentioned punching press hole-flanging device technical scheme, more specifically technical scheme can also be：The top of described depression bar sets
There is guide rod, described guide rod is coated with briquetting；It is equipped with seesaw described in plug-in mounting in the bottom of described depression bar and described drive rod
The plug-in opening of termination.
Further, described lower mould is respectively equipped with the fairlead supporting described drive rod and the lifting of described depression bar.
Further, the termination at described seesaw two ends is bulb.
Due to employing technique scheme, the present invention compared with prior art has the advantages that：1st, whole punching
Pressure aperture apparatus structure is simple, is changed into moving upwards by moving downward of pressure head by a seesaw with central shaft, driving is turned over
Hole punch moves upwards, realizes the operation of hole flanging from the bottom up；2nd, once die-filling just can complete the shaping of big shape covering, turn over
The operations such as hole, flanging, improve work efficiency.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
Punching press hole-flanging device as shown in Figure 1 includes being located at multiple hole flanging dies 7 of mould 10 and is located at dividing of lower mould 11
Not corresponding with hole flanging die 7 multiple Burring Punchs 6；The present embodiment is fixed equipped with two hole flanging dies 7 on upper mould 10,
Fix equipped with two Burring Punchs 6 corresponding with hole flanging die 7 respectively on lower mould 11；In lower mould 11 equipped with two seesaws 4,
Each seesaw 4 is all hinged on lower mould 11 by central shaft 5；It is provided with drive rod 12 in one end of seesaw 4, drive rod 12 has and sets
The push rod be connected in first guide rod on top and with the second guide rod；The other end of drive rod 12 is provided with inserting of plug-in mounting seesaw 4 termination
Dress hole, the termination of seesaw 4 one end is inserted into the plug-in mounting in the hole of drive rod 12；It is provided with depression bar 1 in the other end of seesaw 4, depression bar 1 has
There is the second guide rod being located at top, the second guide rod is coated with briquetting 9, the other end of depression bar 1 is provided with inserting of plug-in mounting seesaw 4 termination
Dress hole, the termination of the other end of seesaw 4 is inserted into the plug-in mounting in the hole of depression bar 1；The termination at the two ends of seesaw 4 is preferably bulb.Under
Mould 11 is set with the fairlead 13 supporting drive rod 12 lifting outside the push rod of drive rod 12, and fairlead 13 is contained in leading of lower mould 11
To in the hole；It is set with the fairlead 3 supporting depression bar 1 lifting outside depression bar 1, fairlead 3 is contained in the guiding in the hole of lower mould 11.This reality
Apply example when the state that upper mould 10 is in matched moulds with lower mould 11, two Burring Punchs 6 of lower mould 11 are turned over two of upper mould 10 respectively
Hole die 7 abuts against；The push rod of drive rod 12 sequentially passes through Burring Punch 6 and hole flanging die 7.
During punching press, the sheet metal component 8 that two pieces punching is had preformed hole is contained on lower mould 11, the Burring Punch 6 of lower mould 11 and upper mould
10 hole flanging die 7 is located above and below preformed hole respectively；Matched moulds, when press is moved downward by pressure head 2, pressure head 2 will
Active force acts on depression bar 1 by briquetting 9, and seesaw 4 rotarily drives drive rod 12 around central shaft 5 under the compressing of depression bar 1
Push rod moves upwards, and push rod moves upwards to preformed hole and shapes the sheet material hole flanging of preformed hole periphery；Once die-filling can be simultaneously complete
Become flanging, the stretching operation of sheet metal component 8 one side, the hole flanging operation of another side, improve work efficiency.
