Abstract

The invention provides an edge distance punching die which comprises an upper die base, a lower die base, a male die and a female die. The edge distance punching die is characterized in that the male die is arranged on the lower die base, the female die is arranged on the upper die base, a striking rod is penetratingly arranged in the middles of the female die and the upper die base, a discharging plate is arranged at the top of the male die, and a discharging bolt is arranged between the discharging plate and the lower die base. The edge distance punching die is simple in structure, reasonable in arrangement and convenient to use; due to the flip-over type structure, the female die is not easy to damage, service life of the die is prolonged, punching of workpieces in which small holes are too close to edges can be completed efficiently, production efficiency is greatly improved, and production cost is saved.

Description

A kind of back gauge punching die

Technical field

The present invention relates to a kind of mould, be specifically related to a kind of back gauge punching die.

Background technology

In production process, usually need workpiece to carry out punching, generally adopt punching die.But, the pitch-row of filling if required from the edge of workpiece especially close to, back gauge spy in hole is little, so general punching die cannot meet Production requirement.

Summary of the invention

goal of the invention: object of the present invention is just to provide a kind of back gauge punching die.

technical scheme:for achieving the above object, the present invention has taked following technical scheme:

A kind of back gauge punching die, comprise upper bolster, die shoe, punch, die, it is characterized in that: described punch is located on described die shoe, described die is located at described upper bolster, in the middle of described die and upper bolster, be equipped with knockout rod, described punch top is provided with stripper, between described stripper and die shoe, is provided with unloading bolt.Die of the present invention is upper, punch under, be flip-over type perforating press; the thickness of die can change as required like this, thereby has protected die, during use; workpiece is placed on stripper, adjusts position, along with upper bolster moves down; die, punch and stripper three jointly to workpiece effect hole is gone out; after punching, upper bolster is up, and workpiece is pushed out under the effect of stripper; waste material is pushed out from knockout rod, thereby has completed the back gauge punching of workpiece.

Described punch both sides are provided with punch protective sleeve and punch retainer from inside to outside successively, away from the punch retainer of described unloading bolt one side, are provided with spring, and described spring connects described punch retainer and stripper.

Described die shoe is provided with backing plate, and described backing plate connects bottom and the described die shoe top of described punch, punch protective sleeve and punch retainer.

Described die both sides are provided with die block.

Described upper bolster is provided with die shank, and described die shank is positioned at the both sides of described knockout rod.

One end of described upper bolster, die shoe is connected with guide pillar, and described guide column sleeve has guide pin bushing.

Described stripper bottom is trapezoidal notch.

Described punch retainer, punch protective sleeve, backing plate, curtain calls are done all as stripper, dig out part, and bottom is trapezoidal notch.

beneficial effect:adopt the present invention of technique scheme to have the following advantages:

The present invention is simple in structure, arranges rationally, easy to use, the structure of flip-over type, makes die not fragile, and the service life of mould is elongated, can complete efficiently the punching of some small pitchs workpiece close to very from back gauge, improve greatly production efficiency, save production cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the cutaway view of the bottom of the stripper in the present invention;

In figure: 1-unloading bolt, 2-punch retainer, 3-punch protective sleeve, 4-punch, 5-die block, 6-knockout rod, 7-die shank, 8-upper bolster, 9-guide pin bushing, 10-die, 11-stripper, 12-spring, 13-guide pillar, 14-backing plate, 15-die shoe.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further set forth.

As shown in Figure 1-2: a kind of back gauge punching die of the present invention, comprise upper bolster 8, die shoe 15, punch 4, die 10, it is characterized in that: described punch 4 is located on described die shoe 15, described die 10 is located at described upper bolster 8, described die 10 and the middle knockout rod 6 that is equipped with of upper bolster 8, described punch 4 tops are provided with stripper 11, between described stripper 11 and die shoe 15, be provided with unloading bolt 1, described punch 4 both sides are provided with punch protective sleeve 3 and punch retainer 2 from inside to outside successively, punch retainer 2 away from described unloading bolt 1 one sides is provided with spring 12, described spring 12 connects described punch retainer 2 and stripper 11, described die shoe 15 is provided with backing plate 14, described backing plate 14 connects described punch 4, the bottom of punch protective sleeve 3 and punch retainer 2 and described die shoe 1 top, described stripper 11 bottoms are trapezoidal notch.

The course of work of the present invention and principle are as follows:

The present invention and forcing press support the use, during use, back gauge punching die is installed with forcing press on, workpiece is placed on stripper 11, be adjusted to correct position, forcing press moves down, die 10 moves down thereupon, then die 10, punch 4 and stripper 11 threes carry out punching to workpiece jointly, after punching finishes, on forcing press, move, die 10 separates with workpiece, workpiece discharging under the effect of stripper 11 is removed, production waste is by knockout rod 6 ejection dies, so just completed the back gauge punching of workpiece, flip-over type mould of the present invention can complete the punching of some small pitchs workpiece close to very from back gauge efficiently, improved greatly production efficiency, saved production cost.

Below be only a kind of specific embodiment of the present invention; should understand these embodiments is only 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.
