Background technology

In prior art, during thick-plate parts, generally adopt line cutting processing part in processing, work more time-consuming and efficient is lower, cost is high again, can only carry out single operation production, can't satisfy production in enormous quantities.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of high efficiency, time saving and energy saving, low cost of manufacture are provided, can satisfy the slab blanking die of production in enormous quantities.

According to technical scheme provided by the invention, described slab blanking die is made up of mold and bed die and jockey outer guiding post.Described mold comprise fixed head mold insert, stripper mold insert, drift, inner guiding post, upper bolster, on fixedly backing plate, upper mounted plate, stripper backing plate and stripper; Described bed die comprises interior guide pin bushing, outer guiding post, concave template, lower bolster, die shoe, limited block, interior guide pin bushing, reference column, push rod and alignment pin;

The upper bolster of described mold, on fixedly backing plate and upper mounted plate are fixed by screw, upper mounted plate, stripper backing plate and stripper are fixed by the discharging screw, going up fixedly, backing plate is connected by screw with upper mounted plate, nitrogen spring is fixed on the upper bolster by screw, stripper backing plate and stripper are fixed by screw, the fixed head mold insert is locked on the fixed head by screw, drift directly is fixed in the fixed head mold insert, the stripper mold insert is screwed on stripper, and inner guiding post directly is fixed on the upper mounted plate;

The die shoe of described bed die, lower bolster and concave template are fixed by screw, and locate mutually with alignment pin, the die mold insert is fixed on the concave template by screw, limited block is fixed on the concave template by screw, reference column directly is set on the concave template, interior guide pin bushing and interior guide pin bushing directly are set in concave template and the stripper, and the back side of push rod is withstood fixing by spring and plug screw, and part is fixed in the middle of die mold insert and the limited post;

Described outer guiding post directly is set in the upper bolster and by screw and is locked in the die shoe.

Compact conformation of the present invention, rationally; The course of work is very easy, safe in utilization, can increase substantially the security of production efficiency and production, is particularly suitable for the thick stamping parts of sheet material.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present invention.

The specific embodiment

The invention will be further described below in conjunction with concrete drawings and Examples.

As shown in the figure: the slab blanking die, constitute by mold A, bed die B and outer guiding post 14, described mold A comprise fixed head mold insert 6, stripper mold insert 8, drift 10, inner guiding post 12, upper bolster 15, on fixedly backing plate 16, upper mounted plate 17, stripper backing plate 18, stripper 19; Described bed die B comprises interior guide pin bushing 13, outer guiding post 14, concave template 20, lower bolster 21, die shoe 22, limited block 23, interior guide pin bushing 25, reference column 28, push rod 29, alignment pin 32, part 34;

The upper bolster 15 of described mold A, upward fixedly backing plate 16 and upper mounted plate 17 are fixing by screw 11, upper mounted plate 17, stripper backing plate 18 and stripper 19 are fixing by discharging screw 3, going up fixedly, backing plate 16 is connected by screw 5 with upper mounted plate 17, nitrogen spring 1 is fixed on the upper bolster 15 by screw 2, stripper backing plate 18 and stripper 19 are fixing by screw 4, fixed head mold insert 6 is locked on the fixed head 17 by screw 7, drift 10 directly is fixed in the fixed head mold insert 6, stripper mold insert 8 usefulness screws 9 are fixed on the stripper 19, and inner guiding post 12 directly is fixed on the upper mounted plate 17;

The die shoe 22 of described bed die B, lower bolster 21 and concave template 20 are fixing by screw 33, and locate mutually with alignment pin 32, die mold insert 26 is fixed on the concave template 20 by screw 27, limited block 23 is fixed on the concave template 20 by screw 24, reference column 28 directly is set on the concave template 20, interior guide pin bushing 25 and interior guide pin bushing 13 directly are set in concave template 20 and the stripper 19, the back side of push rod 29 is withstood fixing by spring 30 and plug screw 31, play the discharging effect, part 34 is fixed in the middle of die mold insert 26 and the limited post 28;

Described outer guiding post 14 directly is set in the upper bolster 15 and by screw and is locked in the die shoe 22.

The operation principle of mould of the present invention and the course of work

The present invention is by hydraulic press production, reduce the blade clearance, when mould is closed, drift exposes stripper cuts off part, simultaneously because part is thicker, so corresponding stripping force is also bigger, to carry out binder with the nitrogen cylinder, entire work process is very free and relaxed, and is time saving and energy saving, and ram efficiency is also high.

During mould manufactured parts of the present invention, it is descending that hydraulic press drives patrix, and after holding pad was pushed down part 34, mould continued descending, and along with mold stroke reduces, drift 10 exposes part 34 gradually, thereby part 34 is cut off.In punching course, four nitrogen springs 1 provide stable and very big pressure-plate-force, and the mould blade clearance is greatly about about monolateral 0.05MM, thereby the part that has guaranteed punching press is the euphotic belt that has greater than 70%, has satisfied client's instructions for use.
