Abstract
The invention discloses a kind of Z-shaped part bending die, including top plate, punch-pin, upper bolster, rubber, punch-pin supporting plate, movable punch, die shoe；Top plate is movably connected on die shoe by push rod, and punch-pin is fixed on upper bolster, and the lower end of punch-pin passes through punch-pin supporting plate, and the lower end of punch-pin is corresponding with top plate right positions；Movable punch is movably connected on upper bolster by punch-pin supporting plate, and the lower end of movable punch is corresponding with top plate leftward position, and rubber is set between upper bolster and punch-pin supporting plate；Before stamping movable punch in the presence of rubber with punch-pin end face；During punching press, movable punch is with top plate by blank holding, and because the elastic force pressure that rubber is produced is more than the bullet top power below top plate produced by buffer, promoting top plate to move down makes blank left-end bent；After top plate contact die shoe, rubber compression, then punch-pin is moved down blank right-hand member bending forming relative to movable punch.
Description
Technical field
The present invention relates to a kind of Z-shaped part bending die.
Background technology
At present, existing simple Z-shaped part first order buckling is formable, but due to no material pressing device, blank during press-bending
Easily slide, be only applicable to less demanding part.
The content of the invention
Purpose：In order to overcome the deficiencies in the prior art, the present invention provides a kind of Z-shaped part bending die.
Technical scheme：In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of Z-shaped part bending die, it is characterised in that：Including top plate, punch-pin, upper bolster, rubber, punch-pin supporting plate, movable punch, under
Die holder；
Top plate is movably connected on die shoe by push rod, and punch-pin is fixed on upper bolster, and the lower end of punch-pin passes through punch-pin supporting plate,
And the lower end of punch-pin is corresponding with top plate right positions；
Movable punch is movably connected on upper bolster by punch-pin supporting plate, and the lower end of movable punch is relative with top plate leftward position
Should, rubber is set between upper bolster and punch-pin supporting plate；
Before stamping movable punch in the presence of rubber with punch-pin end face；During punching press, movable punch and top plate are by blank
Compress, because the elastic force pressure that rubber is produced is more than the bullet top power below top plate produced by buffer, promoting top plate to move down makes blank
Left-end bent；After top plate contact die shoe, rubber compression, then punch-pin moves down relative to movable punch and bends to blank right-hand member
Shape.
Preferably, described a kind of Z-shaped part bending die, it is characterised in that：Set between the die shoe and top plate
Briquetting of tossing about is put, the offsetting power for overcoming horizontal direction between upper and lower mould, while being oriented to for top plate, prevents its play.
Preferably, described a kind of Z-shaped part bending die, it is characterised in that：The briquetting of tossing about is solid by bolt
It is scheduled on die shoe.
Preferably, described a kind of Z-shaped part bending die, it is characterised in that：Between upper bolster and punch-pin supporting plate also
It is provided with lead.
Preferably, described a kind of Z-shaped part bending die, it is characterised in that：Pressure is provided with the punch-pin supporting plate
Block, when briquetting is collided with upper bolster, whole workpiece is corrected.
Preferably, described a kind of Z-shaped part bending die, it is characterised in that：Set between the bedplate and top plate
It is equipped with alignment pin.
Further, described a kind of Z-shaped part bending die, it is characterised in that：Offered on the bedplate for positioning
Sell through through hole, alignment pin is connected through bedplate and alignment pin top with top plate.
Beneficial effect：A kind of Z-shaped part bending die that the present invention is provided, has the Z-shaped part bending die of top plate and alignment pin, can have
Effect prevents the skew of blank.The effect of briquetting of tossing about is the offsetting power for overcoming horizontal direction between upper and lower mould, while being also top plate
It is oriented to, prevents its play.Before stamping movable punch in the presence of rubber with punch-pin end face.During punching press movable punch with
Blank holding because the elastic force pressure that rubber is produced is more than the bullet top power below top plate produced by buffer, is promoted top plate by top plate
Moving down makes blank left-end bent.After top plate contact die shoe, rubber compression, then punch-pin is moved down blank relative to movable punch
Right-hand member bending forming.When briquetting and upper bolster are collided, whole workpiece is corrected.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：Top plate 1, alignment pin 2, briquetting 3 of tossing about, punch-pin 4, lead 5, upper bolster 6, briquetting 7, rubber 8, punch-pin support
Plate 9, movable punch 10, die shoe 11.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of Z-shaped part bending die, including top plate 1, alignment pin 2, briquetting 3 of tossing about, punch-pin 4, lead 5,
Upper bolster 6, briquetting 7, rubber 8, punch-pin supporting plate 9, movable punch 10, die shoe 11.Top plate 1 is movably connected in lower mould by push rod
On seat 11, punch-pin 4 is fixed on upper bolster 6, and the lower end of punch-pin 4 passes through the lower end and the right side of top plate 1 of punch-pin supporting plate 9 and punch-pin 4
Position is corresponding；Movable punch 10 is movably connected on upper bolster 6 by punch-pin supporting plate 9, lower end and the top plate 1 of movable punch 10
Leftward position is corresponding, and rubber 8 is set between upper bolster 6 and punch-pin supporting plate 9,
Before stamping movable punch 10 in the presence of rubber 8 with the end face of punch-pin 4.During punching press, movable punch 10 and top plate 1
By blank holding, the bullet top power produced by the lower section buffer of top plate 1 is more than due to the elastic force pressure that rubber 8 is produced, is promoted under top plate
Shifting makes blank left-end bent；After top plate 1 contacts die shoe 11, rubber 8 is compressed, then punch-pin 4 is moved down relative to movable punch 10
By blank right-hand member bending forming.
There is the Z-shaped part bending die of top plate 1 and alignment pin 2, can effectively prevent the skew of blank.The effect of briquetting 3 of tossing about is
Overcome the offsetting power of horizontal direction between upper and lower mould, while being also oriented to for top plate 1, prevent its play.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
