Description

A kind of many carbide alloy automatic moulding moulds

Technical field

The utility model relates to carbide alloy and manufactures the mould in field, is specifically related to a kind of many carbide alloy automatic moulding moulds.

Background technology

A kind of alloy material that carbide alloy is made up by powder metallurgical technique of hard compounds and the binding metal of refractory metal.Carbide alloy has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, is widely used in cutter material.Because China carries out actively sane macro policy, whole fast of national economy, carbide alloy demand also grows at top speed.

The general single mode moulds that adopt of mould on tradition carbide alloy forcing press, are made up of a drift and single die and punch more, drift mostly be fixedly connected with support on.This mould not only production efficiency is low, and in the time that drift damages, changes quite trouble, will directly affect manufacturing schedule and indirectly cause certain economic loss.

Utility model content

A kind of automatic moulding mould that technical problem to be solved in the utility model is to provide a kind of deficiency and can enhances productivity.

For solving the problems of the technologies described above, the utility model provides a kind of many carbide alloy automatic moulding moulds, it comprises punch, some drifts and die, on described punch, be evenly equipped with some step grooves, described punch is provided with shoulder, described drift top is that hemispherical groove is welded on push rod, and described drift and described push rod are positioned in the step groove in described punch, is evenly equipped with some material cavities in described die.

Further, the described material cavity center of circle is positioned on same circle and matches with described drift size.

Further, the central axis of described step groove is positioned on same circle, is provided with screwed hole for fixing described punch between adjacent step groove, and described screwed hole central axis is positioned on same circle.

Further, described drift and described punch adopt matched in clearance.

Further, described die middle part withdrawing pattern degree is 10 °.

Further, described step groove one end groove depth is less than the height of shoulder of described punch, can make so described drift in the time of work, keep stablizing and not damaging the working strength of described punch.

Further, described drift for being flexibly connected, is convenient to dismounting with described punch, has reduced the replacing time, makes more convenient to operate.

The beneficial effects of the utility model are: the drift of the flexible connection that the utility model adopts and punch and the die matching with it, can realize many product synchronous production, become multiple products from original single product production and produce simultaneously, the scale error between product reduces the requirement that meets batch production; Operation and replacing drift are simple, and in the situation that ensureing product quality, have greatly improved production efficiency.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further set forth.

As shown in Figures 1 to 7, a kind of many carbide alloy automatic moulding moulds, it comprises punch 5, four drifts 1 and dies 3, on punch 5, be evenly equipped with four step grooves 6, punch 5 is provided with shoulder 8, drift 1 top is that hemispherical groove 2 is welded on the push rod 9 of drift 1, and hemispherical groove 2 shapes can reduce stressed punching press to be more prone to; Drift 1 is positioned in the step groove 6 in punch 5 with push rod 9, is evenly equipped with four material cavities 4 in die 3, and when use, punch 5 drives drift 1 undershoot and die 3 to interact and form product in material cavity 4.

As shown in figures 1 and 3, the center of circle of four material cavities 4 is positioned on same circle and with four drift 1 sizes and matches, and can make the scale error between product reduce, and meets the requirement of batch production.

The central axis of four of punch 5 step grooves 6 is positioned on same circle as shown in Figures 4 to 7, and between two adjacent step grooves 6, is provided with a screwed hole 8 and is positioned on same circle for 5, four screwed hole 8 central axis of solid punch.

Preferably, drift 1 adopts matched in clearance with punch 5, avoids causing drift 1 precision reduce or be out of shape because drift moves back and forth to produce to rub with punch 5.

As shown in Figure 2 and Figure 3, die 3 middle part withdrawing pattern degree are 10 °, can increase the working strength of convex-concave 3, the pressure being subject to can be decomposed to be unlikely to concentrate on simultaneously and can effectively improve die life.

As shown in Figure 4, Figure 5, step groove 6 bottom groove depth are less than shoulder 7 height of punch 5, can make like this drift 1 in the time of work, keep stablizing and not damaging the working strength of punch 5.

In addition, drift 1 for being flexibly connected, is convenient to dismounting with punch 5, has reduced the replacing time, makes more convenient to operate.

When assembling, drift 1 is positioned in punch 5 and with die 3 placement that matches, punch 5 is installed on to press upper end, die 3 is fixed under punch 5, after die trial, detect dimensional accuracy and then produce in batches.

More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; in the prerequisite that does not depart from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
