Abstract
The invention discloses a vehicle door plate punching hole flanging method and relates to the technical field of a punching manufacture process. A punching hole flanging device is used, and the method comprises the operation steps that a plurality of blank plates are placed on a lower mold, reserved holes of the blank plates correspond to a hole flanging male mold, and the mold matching is carried outs; a press machine is started, a press head acts on the top of the upper mold so that the upper mold carries out flanging and drawing formation on one sides of the blank plates; the press head acts on a press block, the press block drives a driving rod to upwards move through a press rod and a seesaw, a push rod of the driving rod sequentially passes through the hole flanging male mold, the reserved holes of the blank plates and a hole flanging female mold to carry out upward punching hole flanging on the reserved holes of the blank plates; and the mold splitting is carried out, a vehicle door plate is unloaded, and the punching hole flanging of the vehicle door plate is completed. Compared with the prior art, the vehicle door plate punching hole flanging method has the advantage that the flanging and drawing operation at one side of the vehicle door plate and the punching hole flanging operation at the other side of the vehicle door plate can be simultaneously completed through one-step mold feeding.
Description
Technical field
The present invention relates to stamped technology field, especially a kind of process be shaped for the cladding element punching to automobile.
Background technology
Automobile panel has that size is large, relative thickness is little, the discrepancy in elevation is larger, usually will could be stamping through repeatedly drawing; Especially a kind of door panel of BS3 vehicle is established a plurality of hole flangings that make progress on door panel.At present, the hole flanging method of this door panel is, 1, use mould to be drawn door panel; 2, at the preformed hole that completes punching hole flanging on the door panel of drawing operation, 3, use unsteady mould hole flanging on preformed hole to complete; There are the following problems in process of production for this pressure method: need two molds and carry out secondary dress mould, die cost improves, and production efficiency is low.
Summary of the invention
A kind of method that the purpose of this invention is to provide door panel punching press hole flanging, the method for this door panel punching press hole flanging is used a kind of pressure aperture apparatus, once fills mould and can complete the drawing of door panel one side, flanging operation, the hole flanging operation of another side simultaneously.
In order to address the above 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 a plurality of hole flanging dies of being located at patrix and a plurality of Burring Punchs corresponding with described hole flanging die respectively that are located at counterdie, described counterdie is provided with a plurality of seesaws, and each described seesaw is all hinged by central shaft and described counterdie; An end at described seesaw is provided with drive rod, and described drive rod has the guide rod that is located at top and the push rod be connected with described guide rod; The other end at described seesaw is provided with depression bar; When described patrix and described counterdie are the state of matched moulds, described Burring Punch and described hole flanging die connect; Described push rod installed described Burring Punch and described hole flanging die successively;
Its operating procedure comprises:
A, clamping: the described blanket of polylith is placed on described counterdie, makes 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, makes 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 by described depression bar and described seesaw and moves upward, the push rod of described drive rod successively through the described preformed hole of described Burring Punch, described blanket and described hole flanging die to the described preformed hole of the described blanket punching press hole flanging that makes progress;
D, parting, unload the punching press hole flanging that door panel completes door panel.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect: 1, once fill mould and just can complete the drawing of door panel one side, flanging operation simultaneously, the hole flanging operation of another side, improved operating efficiency; 2, by a seesaw with central shaft, moving downward of pressure head become to the driving Burring Punch that moves upward and move upward and coordinate the preformed hole position extruding to sheet metal component with the hole flanging die, realize the operation of hole flanging from the bottom up, simple, quick.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Punching press hole-flanging device as shown in Figure 1 comprises a plurality of hole flanging dies 7 that are located at patrix 10 and is located at a plurality of Burring Punchs 6 corresponding with hole flanging die 7 respectively of counterdie 11; The present embodiment fixedly is equipped with two hole flanging dies 7 on patrix 10, and two Burring Punchs 6 corresponding with hole flanging die 7 respectively fixedly are housed on counterdie 11; At counterdie 11, two seesaws 4 are housed, each seesaw 4 all is hinged on counterdie 11 by central shaft 5; An end at seesaw 4 is provided with drive rod 12, and drive rod 12 has the guide rod that is 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 terminations, and the termination of seesaw 4 one ends is inserted in the plug-in opening of drive rod 12; The other end at seesaw 4 is provided with depression bar 1, and depression bar 1 has the guide rod that is located at top, is coated with briquetting 9 on guide rod, and the other end of depression bar 1 is provided with the plug-in opening of plug-in mounting seesaw 4 terminations, 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 liftings outside the push rod of drive rod 12, and fairlead 13 is contained in the pilot hole of counterdie 11; Be set with the fairlead 3 that supports depression bar 1 lifting outside depression bar 1, fairlead 3 is contained in the pilot hole of counterdie 11.When the present embodiment is the state of matched moulds when patrix 10 and counterdie 11, two Burring Punchs 6 of counterdie 11 connect 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.
