Background technology
Automobile panel has that size is large, relative thickness is little, the discrepancy in elevation is comparatively large, usually will through repeatedly drawing could be stamping; Especially a door panel for BS3 vehicle, door panel is established multiple hole flanging upwards.At present, the hole flanging method of this door panel is, 1, use mould drawing is carried out to door panel; 2, the preformed hole of punching hole flanging in the door panel completing drawing operation, 3, use the mould hole flanging on preformed hole floated namely to complete; There are the following problems in process of production for this pressure method: need two molds and to carry out secondary die-filling, and die cost improves, and production efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of method of door panel punching press hole flanging, the method for this door panel punching press hole flanging uses a kind of pressure aperture apparatus, once die-filling drawing, the flanging operation that simultaneously can complete door panel one side, the hole flanging operation of another side.
In order to solve the problem, the technical solution used in the present invention is: the method for this door panel punching press hole flanging, punching preformed hole on the blanket of door panel; Use a kind of punching press hole-flanging device, this punching press hole-flanging device comprises the multiple hole flanging die being located at patrix and the multiple Burring Punchs corresponding with described hole flanging die being respectively located at counterdie, described counterdie is provided with multiple seesaw, each described seesaw all by central shaft and described counterdie hinged; Be 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 be connected with described guide rod; Depression bar is provided with at the other end of described seesaw; When described patrix and described counterdie are the state of matched moulds, described Burring Punch and described hole flanging die abut against; Described push rod installed described Burring Punch and described hole flanging die successively;
Its operating procedure comprises:
A, clamping: be placed on described counterdie by blanket described in polylith, make the described preformed hole of described blanket corresponding with described Burring Punch, matched moulds;
B, starting pressure machine, act on described patrix top by pressure head, make patrix carry out flanging, draw forming to the one side of described blanket;
C, pressure head is acted on described briquetting, described briquetting drives described drive rod to move upward by described depression bar and described seesaw, and the push rod of described drive rod carries out upwards punching press hole flanging through the described preformed hole of described Burring Punch, described blanket and the described preformed hole of described hole flanging die to described blanket successively;
D, parting, unload the punching press hole flanging that namely door panel completes door panel.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, once die-filling drawing, the flanging operation that just simultaneously can complete door panel one side, and the hole flanging operation of another side, improves operating efficiency; 2, by the seesaw of a band central shaft pressure head moved downward that becoming moves upward drives Burring Punch to move upward and coordinates with hole flanging die and extrude the preformed hole position of sheet metal component, realize the operation of hole flanging from the bottom up, simply, fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Punching press hole-flanging device as shown in Figure 1 comprises the multiple hole flanging dies 7 being located at patrix 10 and the multiple Burring Punchs 6 corresponding with hole flanging die 7 being respectively located at counterdie 11; The present embodiment is fixedly equipped with two hole flanging dies 7 on patrix 10, and counterdie 11 is fixedly equipped with two corresponding with hole flanging die 7 respectively Burring Punchs 6; At counterdie 11, two seesaws 4 are housed, each seesaw 4 is all hinged on counterdie 11 by central shaft 5; Be provided with drive rod 12 in one end of seesaw 4, drive rod 12 has the guide rod being located at top and the push rod be connected with guide rod; The other end of drive rod 12 is provided with the plug-in opening of plug-in mounting seesaw 4 termination, and the termination of seesaw 4 one end is inserted in the plug-in opening of drive rod 12; Be provided with depression bar 1 at the other end of seesaw 4, depression bar 1 has the guide rod being located at top, guide rod is coated with briquetting 9, and the other end of depression bar 1 is provided with the plug-in opening of plug-in mounting seesaw 4 termination, and the termination of the other end of seesaw 4 is inserted in the plug-in opening of depression bar 1; The termination at the two ends of seesaw 4 is preferably bulb.Counterdie 11 is set with the fairlead 13 of support drive bar 12 lifting outside the push rod of drive rod 12, and fairlead 13 is contained in the pilot hole of counterdie 11; Outside depression bar 1, be set with the fairlead 3 supporting depression bar 1 and be elevated, fairlead 3 is contained in the pilot hole of counterdie 11.The present embodiment is when patrix 10 is the state of matched moulds with counterdie 11, and two Burring Punchs 6 of counterdie 11 abut against with two hole flanging dies 7 of patrix 10 respectively; The push rod of drive rod 12 installed Burring Punch 6 and hole flanging die 7 successively.
