Abstract

The utility model relates to an automobile panel punch forming die, which is characterized in that ejector rods are arranged in all ejector rod installation holes in the worktable of a punching machine, avoidance holes which are matched with the ejector rods are arranged in the lower die plate of the die, a lower die is a hollow male die, the shape of the convex surface is matched with the molding surface of a workpiece, and the lower die is fixedly arranged on the lower die plate through lower die installation seats which are arranged around the lower die. The automobile panel punch forming die has the advantages that the die is simple to operate, the safety and the reliability are high, the damages caused by incorrect placement of the ejector rod to the die can be avoided, the product manufacturing cost is reduced and the production efficiency is improved.

Description

A kind of vehicle cladding element punching mould

Technical field

The utility model relates to a kind of stamping die of automotive covering part, is particularly useful for utilizing the drawing and moulding processing of the whole push rods of press machine, belongs to the metal stamping technical field.

Background technology

At automobile manufacturing enterprise; Processing to body outer skin generally is with the sheet metal drawing and moulding through press machine; Its processing step is: after the die sinking, push rod cooperates the jack-up blank holder with secondary extension bar on the blank holder, after metal blank is placed on the blank holder; Patrix is descending jointly slab perimeter is clamped with blank holder after; Continue descendingly down in guiding mechanism guiding, that the metal blank that is arranged in die cavity matees is protruding, the die shape is carried out plasticity extension modification, obtains the workpiece that conforms to designing requirement thus.

Along with the adjustment of continuing to optimize of automobile industry, enterprise proposes increasingly high requirement to cost of goods manufactured and production efficiency.In the vehicle cladding element punching process, the convenience of push rod Mould operation, reliability all directly affect the height of production efficiency.And at present cladding element stamping process is to confirm that according to product moulding cae analysis result the arrangement form of push rod on lathe, jack-up are highly and the size of pressure is provided; Owing to gather in platen upper ejector pin hole; Be prone to cause push rod placement location mistake; Thereby cause in process of production, the phenomenon that push rod is scrapped the mould top takes place.

The utility model content

The purpose of the utility model is the drawback to prior art, provide a kind of simple to operate, safe and reliable, can avoid placing the wrong vehicle cladding element punching mould that causes mould to damage because of push rod.

The said problem of the utility model realizes with following technical proposals:

A kind of vehicle cladding element punching mould; Its special feature is: it all is provided with push rod in all push rod installing holes of press machine workbench; On the lower mould plate, be provided with the hole of dodging with the push rod coupling; Counterdie is the punch of hollow, and convex shape and workpiece die mould face coupling are fixed on the lower bolster through the counterdie mount pad that is arranged in its peripheral position.

Above-mentioned vehicle cladding element punching mould, its special feature also is: saidly dodge the hole and the push rod gap is not less than 10mm, dodge hole circle segmental arc diameter D >=d (push rod 4 diameters)+20mm.

Above-mentioned vehicle cladding element punching mould, its special feature also is: saidly dodge distance L 1 >=40mm between the hole.

Above-mentioned vehicle cladding element punching mould, its special feature also is: said hole and the lower bolster edge minimum range L2 >=30mm of dodging.

Above-mentioned vehicle cladding element punching mould, its special feature also is: said push rod ejection height H >=30mm.

The utility model all jogger hole places on press machine all arrange push rod, and the generation of not only having avoided the push rod position to place error situation has realized mould assembling zero error rate; And in the mould assembling process, need not arrange that sketch map installs push rod according to push rod, improved the mould efficiency of assembling greatly; In addition, after the lathe push rod was arranged and accomplished, push rod did not need to adjust just again and can directly use in the process of postorder.The utility model is simple to operate, safe and reliable, can avoid placing the wrong mould that causes because of push rod damages, thereby has reduced cost of goods manufactured, has improved production efficiency.

Each label is among the figure: 1, lower bolster, 1-1, dodge the hole, and 2, counterdie, 2-1, counterdie mount pad, 3, platen, 4, push rod, 5, blank holder, 6, the secondary extension bar.

The specific embodiment

With the punch forming of automobile engine hood panel a specific embodiment as the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4; The utility model and traditional mould difference are: it all is provided with push rod 4 in all push rod installing holes of press machine workbench 3; On lower mould plate 1, be provided with push rod coupling dodge hole 1-1; Counterdie 2 is the punch of hollow, and convex shape and workpiece die mould face coupling are fixed on the lower bolster 1 through the counterdie mount pad 2-1 that is arranged in its peripheral position.

Referring to Fig. 2, Fig. 4, Fig. 5, the special feature of the utility model also is: saidly dodge hole 1-1 and push rod 4 gaps are not less than 10mm, dodge hole circle segmental arc diameter D >=d (push rod 4 diameters)+20mm, to guarantee that push rod ejects smoothly in the process; Saidly dodge distance L 1 >=40mm between the 1-1 of hole, said hole 1-1 and the lower bolster 1 edge minimum range L2 >=30mm of dodging is to guarantee lower bolster intensity.

Referring to Fig. 2, Fig. 4, Fig. 6, the special feature of the utility model also is: said push rod 4 ejection height H >=30mm, and to guarantee the coupling of push rod 4 and blank holder secondary extension bar.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the CAD mentality of designing of the utility model is: one, platen 3 is called in the working environment, then upper ejector pin 4 is all arranged in jogger hole positions all on the platen 3.Two, according to the moulding needs of product with push rod 3 jack-up certain height H, and then jack-up 30mm, (H is a working depth, and H+30mm is for interfering height).Three, there is the position of interference to offer all and push rod 4 on the lower bolster 1 and dodges hole 1-1.

Referring to Fig. 3, Fig. 6; The course of work and the operation principle of the utility model are: at first upper ejector pin 4 is all arranged in jogger hole positions all on the platen 3; Lathe drives push rod 4 and (dodges hole 1-1 owing to lower bolster 1 is provided with in the push rod position according to designing requirement jack-up certain height H then; Push rod 4 can eject smoothly), with blank holder 5 jack-up, blank holder cooperates with patrix the clamping of workpiece periphery push rod 4 through the secondary extension bar 6 on the blank holder.

The punch forming processing that also is applicable to coverings such as door skin, roof skin of the utility model, its mentality of designing and operation principle repeat no more with last identical.
