Abstract

A kind of porcupine die of drift able to quickly change.Its principal character is: described drift is fixed in monoblock type fixed head, and adopt the mode of ladder punching to reduce blanking pressure, drift divides two kinds of forms, long drift 18, short drift 14; Described monoblock type fixed head is arranged in the seam of cope match-plate pattern by screw after installing drift, and monoblock type fixed head can ensure punching precision; Described backing plate is connected by screw on the cover board, unloads when changing drift with cover plate; Described cover plate is arranged in the groove of cope match-plate pattern by screw, and in cover plate, holes drilled through makes need not to pull down unloading bolt during replacing drift and can complete, and on the cover board surperficial auger shell pit is to dismantle; The groove that described cope match-plate pattern is opened in centre, changes drift by this groove after dismounting cover plate and backing plate; Described unloading bolt head is embedded in cover plate through hole, and the end of thread connects stripper; Described stripper is installed by unloading bolt, bores drift passing hole in stripper.

Description

A kind of porcupine die of drift able to quickly change

Technical field

The utility model relates to a kind of cold stamping porcupine die.

Background technology

Sheet metal component is processed multiple circular hole and has a lot of method, wherein adopt cold punching die disposable punching all well most effective, precision is best.Shortcoming is that stamping press increases, and mould structure is complicated, and assembling and later maintenance difficulty, especially on stamping parts, circular hole quantity is many, the situation that pitch of holes is little.Traditional mounting structure is that drift is fixed on monoblock type fixed head, again monoblock type fixed head is arranged on cope match-plate pattern, when drift changed by needs, monoblock type fixed head, stripper, unloading bolt etc. all must be unloaded, just can complete replacing drift, and Renewal process is very loaded down with trivial details.

Utility model content

The purpose of this utility model is for the problems referred to above, by improving the mounting structure of porcupine die drift, makes can change a certain damage drift easily when not dismantling the parts such as monoblock type fixed head, stripper when in the later stage.

The technical scheme that the utility model adopts is: a kind of porcupine die of drift able to quickly change, comprises 32 drifts, monoblock type fixed head, backing plate, cover plate, cope match-plate pattern, unloading bolt, stripper.Described drift is fixed in monoblock type fixed head, and adopt the mode of ladder punching to reduce blanking pressure, drift divides two kinds of forms, long drift 18, short drift 14; Described monoblock type fixed head is arranged in the seam of cope match-plate pattern by screw after installing drift, and monoblock type fixed head can ensure punching precision; Described backing plate is connected by screw on the cover board, unloads when changing drift with cover plate; Described cover plate is arranged in the groove of cope match-plate pattern by screw, and in cover plate, holes drilled through makes need not to pull down unloading bolt during replacing drift and can complete, and on the cover board surperficial auger shell pit is to dismantle; The groove that described cope match-plate pattern is opened in centre, changes drift by this groove after dismounting cover plate and backing plate; Described unloading bolt head is embedded in cover plate through hole, and the end of thread connects stripper; Described stripper is installed by unloading bolt, bores drift passing hole in stripper.

The mould structure tool that the utility model provides has the following advantages:

1, can crane gear do not used, when not dismantling monoblock type fixed head, stripper, unloading bolt, change drift quickly and easily.

2, disposablely complete porose punching, ensure that efficiency and precision.

Accompanying drawing explanation

Fig. 1 is the part drawing that the utility model relates to; Fig. 2 is patrix sectional view of the present utility model;

In figure: 1. cope match-plate pattern, 2. monoblock type fixed head, 3. backing plate, 4. cover plate, 5. unloading bolt, 6. long drift, 7. stripper, 8. short drift.

Detailed description of the invention

Below in conjunction with embodiment accompanying drawing, the utility model is described further.

As shown in Figure 1, all circular holes in porcupine die described in the utility model disposable punching part drawing.

As shown in Figure 2, during porcupine die brand-new described in the utility model, first backing plate 3 and cover plate 4 are arranged on cope match-plate pattern 1.Then long drift 6 and short drift 8 are loaded monoblock type fixed head 2, then be fixed on together in the seam of cope match-plate pattern 1 lower surface.Polyurethane spring, stripper 7 and unloading bolt 5 are finally installed.When damage because of drift need to change time, unload lower bolster 3 and cover plate 4 and just can take out drift and complete replacing.
