Abstract
The present invention relates to a stamping tool preventing indentation. The stamping tool is capable of preventing a product from being indented by foreign substances put on the product because a pad (160) is fixed to a pad fixing plate (130) and the pad fixing plate is always lifted by elastic force of a spring (150) so that the product is stamped while the pad is inserted inside a die (174); and reducing defective products caused by a user picking up the products falling before a top dead center because the stamped product is lifted up to the top dead center while being inserted in the pad by a gap between a punch and the pad.
Description
Technical field
The present invention relates to the cross cutting modeling device of impression can be prevented, more particularly to the liner that product will be drawn out to outside attached
In liner fixed plate and above seal retainer is pushed away with spring so that liner is located on the inside of mold plate, so as in die cutting product,
Interval is left between drift and liner, prevents the foreign body on product from impression is left on product in cross cutting, and,
Go for cross cutting modeling device { the die cutting of the prevented impression of little product or long and narrow product
molding apparatus for preventing a productfromgettingimprinted}。
Background technology
Punching machine mold is which is available with the machinery that metal material is main material manufacture using the lathe of referred to as punch press
The plasticity and ductility of material cuts the product for producing same specification in a large number.
Segregation apparatuss are attached in upper die after separation is die cut (diecutting), molding in punch press machinery
The device of machining object, and separation pin (also known as plunger or bar is separated) is collided with declutcher control lever and is risen with the rising of upper die,
So as to separate the device of accompanying machining object.
Sectional views of Fig. 1 a for the segregation apparatuss of the punching machine mold of prior art, and Fig. 1 b are to represent rushing in prior art
When the segregation apparatuss of bed mould complete separating action, there is the bad process of impression because there is foreign body between liner and product and show
It is intended to.
The segregation apparatuss of the punching machine mold of prior art, after molding die cutting product, are clipped in liner 20 to separate
Product, when upper die reaches top dead centre, impact release liner 10 with separation bar 11a, and above-mentioned release liner 10 is impacted
Liner promotes 13 so that the impact for putting on liner distribution 13 is transferred to liner 20, so as to be separated from liner 20 using the impulse force
The product of molding.
But, as illustrated, the liner of prior art as above, because liner 20 is solid by liner fixing screws 21
On pin plate 14, therefore, when liner 20 size become it is big when, the weight of liner 20 made by reason ferrous metal and be located at low
In the position of mold 18, so as to as shown in Figure 1 b, when molding is die cut, when drift 30 is skipped to using the elastic force of drift spring 31
During portion cutting products P, because drift 30 and liner 20 descend die pressing product P and foreign body 20a simultaneously, so foreign body is left on shaped article
Impression, cause the bad of product.
In addition, the cross cutting operation for repeating will make the periphery wear of liner, so that the product ratio of cross cutting shape in mold 18
Into shape of product it is little, therefore, complete cross cutting after upper die rise when, the product of cross cutting is not pressed from both sides in the mould and is dropped
To ground.
In addition, in the case where the size of product is big, the shape of liner also becomes big, therefore, because of the weight of liner itself, lining
Pad moved down and pushes away product before top dead centre is reached, so that product falls to ground.
Now, operator cannot catch product with palm and pick up product on the ground using finger, now, easily make
The sheet metal fold of product, so as to reduce the value of product.
To solve the above problems, applicant of the present invention is it is proposed that Korean Patent Room patent 10-2013-0018696
Number " the cross cutting modeling device of impression can be prevented ".But, " can prevent the cross cutting modeling device of impression " of prior art adopts
The structure of liner is held by screw and spring, needs to guarantee to have the space that can arrange screw, ejector pin etc. and can keep away on liner
Exempt from the space interfered between part, the product wider, larger so as to be applied to product, and be difficult to suitable for relatively small horizontal stroke
To and longitudinal size less than below 50mm shapes product.
The content of the invention
It is an object of the invention to overcome the deficiency of prior art and a kind of cross cutting modeling device for preventing impression is provided,
Which leaves interval in die cutting product, between drift and liner, exists so as to prevent from being clipped in the foreign body bed between press and liner
Impression is left on product.
Another object of the present invention is to, there is provided a kind of cross cutting modeling device for preventing impression, liner is fixed on by which
Above-mentioned liner is made to be located at the inner side of mold plate in liner fixed plate and by the spring possessed in above-mentioned liner fixed plate, with punching
Interval is left between head and liner, so as to when cross cutting is to lower dead center, even if there is foreign body foreign body can be also prevented in product on product
On leave impression.
It is a further object of the present invention to provide a kind of cross cutting modeling device for preventing impression, which is without the need on liner
Possess the space of ejector pin and screw, can according to the overall alignment adjustment of shape of product, so as to design freedom, and
And, than the structure for preventing impression of prior art, it is applicable in the manufacture of long and narrow product.
To reach above-mentioned purpose, the cross cutting modeling device of the prevented impression of the present invention, including：Upper die 100, its bag

230 support and by the driving force of hydraulic pressure or motor upwards punching press to be designed shape by product die cuttings such as Copper Foils；Control
Portion (not shown), controls offer to top including to be die cut the products such as Copper Foil by designed shape using above-mentioned drift 220
Multiple control knobs of the driving force of the hydraulic pressure or motor of mould and lower mould.
The cross cutting modeling device of the prevented impression of the present invention is by products such as designed shape punch process Copper Foils
Device, will attach to upper mass 110 and by upper support board 172, pin plate 172, mold plate using the driving force of hydraulic pressure or motor
The upper die of 173 grade compositions is moved to lower dead center, with 220 punching press of drift of lower mould, the products such as Copper Foil is cut into
Designed shape.
Specifically, as shown in Figures 4 and 5, upper die passes through the powered lift of hydraulic pressure or motor, puts product first
It is placed in and possesses after the drift 220 of lower mould 200, declines upper die and complete cross cutting.Now, using positioned at liner
The elastic force of the spring 150 of 140 bottom of fixed plate rises liner fixed plate 140, so as to be fixed on the liner of liner fixed plate 140
160 maintain to rise the state of about 3mm from the bottom surface of mold 174.
In the state of upper die 100 and lower mould 200 are contacted, by 220 die cutting product of drift after, make top
Mould 100 rises, and now, product will be risen with the state for being clipped in liner 160.
When the upper die 100 for rising reaches top dead centre, separation bar 120a and lightning strip 120b collisions, then it is fixed on above-mentioned
The separating plate 120 of separation bar 120a declines and drives liner fixed plate to decline, so that above-mentioned liner 160 projects to mold 174
Outside, the product of cross cutting drops and is removed.
Above-described embodiment only to illustrate rather than restriction, it will be understood by those within the art that, can be with
The present invention is modified, is deformed or equivalent, without departing from the spirit and scope of the present invention, which all should be covered at this
In the middle of bright right.
