Abstract
The invention provides a small hole blanking die. The small hole blanking die comprises an upper die base and a lower die base. The small hole blanking die is characterized in that a downward male die is arranged on the upper die base, a female die facing right the male die is arranged on the lower die base, a stock guide plate is arranged at the top of the male die, one end of the upper die base and one end of the lower die base are connected with a guide column, the outer wall of the guide column is sleeved with a guide sleeve, a stripper bolt is arranged inside the other end of the upper die base, a fixed plate and a stripper plate are sequentially arranged below the upper die base, the stripper bolt penetrates through the fixed plate and the stripper plate, and a punching needle and a lateral blade are arranged between the fixed plate and the stripper plate in a penetrating mode. The small hole blanking die is reasonable in structure, long in service life and high in blanking efficiency for workpieces with multiple rows of dense small holes and small hole diameters.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of blanking die for small hole.
Background technology
In production process, usually need workpiece is carried out to the work of aperture stamping-out, typically use the aperture punch die and carry out work, but common aperture punch die is difficult to implement stamping-out work to being provided with the less workpiece in the intensive aperture of many rows and aperture, even can stamping-out, but the infringement to mould is larger, make shorten the service life of mould.
Summary of the invention
Goal of the invention: purpose of the present invention just is to provide a kind of blanking die for small hole.
Technical scheme:For achieving the above object, the present invention has taked following technical scheme:
A kind of blanking die for small hole, comprise upper bolster, die shoe, it is characterized in that: described upper bolster is provided with downward punch, described die shoe is provided with the die that faces punch, described die top is provided with stock guide, one end of described upper bolster and die shoe is connected with guide pillar, described guide pillar outer wall is provided with guide pin bushing, described upper bolster other end inside is provided with unloading bolt, described upper bolster below is provided with fixed head successively, stripper, described unloading bolt runs through described fixed head, stripper, described fixed head, be equipped with red needle and side edge between stripper, described blanking die for small hole also comprises the discharging elastic force apparatus of vertical direction, described discharging elastic force apparatus comprises polyurethane rubber, pad, push rod, described polyurethane rubber is located on described upper bolster, described pad is located at described polyurethane rubber below, described push rod is located at described pad below, described push rod is arranged between described upper bolster and stripper.
Described side edge is between described push rod and guide pillar.
Be provided with ejector pin between described die shoe and die.
Distance between described fixed head and stripper is 3-8mm.
The length of described side edge is greater than the length of described red needle.
Beneficial effect:Adopt the present invention of technique scheme to have the following advantages:
The present invention is rational in infrastructure, and long service life is high to being provided with the less workpiece stamping-out efficiency in the intensive aperture of many rows and aperture; The present invention adopts built-in guide pillar, guide pin bushing, makes between die, stripper, upper bolster and carries out and the mould guiding, makes the stripper motion steadily, avoids damaging red needle, makes die life long; The discharging elastic force apparatus be provided with can reduce the length of punch and the length of red needle, therefore makes the service life of mould elongated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-guide pillar, 2-guide pin bushing, 3-side edge, 4-push rod, 5-pad, 6-polyurethane rubber, 7-upper bolster, 8-punch, 9-unloading bolt, 10-red needle, 11-fixed head, 12-stripper, 13-stock guide, 14-die, 15-ejector pin, 16-die shoe, 17-workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further set forth.
As shown in the figure: a kind of blanking die for small hole of the present invention, comprise upper bolster 7, die shoe 16, it is characterized in that: described upper bolster 7 is provided with downward punch 8, described die shoe 16 is provided with the die 14 that faces punch 8, described die 14 tops are provided with stock guide 13, described upper bolster 7 is connected with guide pillar 1 with an end of die shoe 16, described guide pillar 1 outer wall is provided with guide pin bushing 2, described upper bolster 7 other end inside are provided with unloading bolt 9, described upper bolster 7 belows are provided with fixed head 11 successively, stripper 12, described unloading bolt 9 runs through described fixed head 11, stripper 12, described fixed head 11, be equipped with red needle 10 and side edge 3 between stripper 12, the discharging elastic force apparatus that also comprises vertical direction, described discharging elastic force apparatus comprises polyurethane rubber 6, pad 5, push rod 4, described polyurethane rubber 6 is located on described upper bolster 7, described pad 5 is located at described polyurethane rubber 6 belows, described push rod 4 is located at described pad 5 belows, described push rod 4 is arranged between described upper bolster 7 and stripper 12, be provided with ejector pin 15 between described die shoe 16 and die 14, the length of described side edge 3 is greater than the length of described red needle 10.
The course of work of the present invention and principle are as follows:
The present invention should support the use with forcing press, during use, workpiece 17 after cutting out is positioned on die 14, workpiece 17 be positioned over red needle 10 under, along with pressing down of forcing press, punch 8 moves down, thereby drive fixed head 11, pressing down of stripper 12, be located at fixed head 11, red needle 10 between stripper 12 also presses down, can realize the punch work to workpiece 17 under the acting in conjunction of red needle 10 and die 14, after punching finishes, ejector pin 15 moves down die, polyurethane rubber 6, pad 5, 4 effects simultaneously of push rod make red needle separate with workpiece, unloading bolt can limit upper bolster 7, move distance on punch 8 and red needle 10 etc., the workpiece of hole punch 17 is taken off to the punch work that just can complete mould from mould, the workpiece 17 of hole punch can carry out next step operation.
It is only below a kind of specific embodiment of the present invention; should understand these embodiments only is not used in and limits the scope of the invention for the present invention is described; after having read the present invention; those skilled in the art all fall within claims of the present invention to the modification of the various equivalent form of values of the present invention and limit, and protection scope of the present invention should be as the criterion with claim of the present invention.
