Abstract

The utility model discloses a formula of dropping hammer powder pressurizing device, including drop hammer, drift, cushion and be used for the die of powder filler, an organic whole is provided with the locating convex block on the cushion, the die case is on the locating convex block, characteristics are that the die comprises double division left die and right die, the die overcoat is equipped with the overcoat, during the drift stretched into the die, the powder was filled between locating convex block and drift, the advantage is because the die comprises double division left die and right die, when the powder compacting shaping after, takes away the overcoat, with left die and right die separate for double alright take out the pressed compact, this drawing of patterns that not only makes things convenient for the pressed compact makes the pressed compact not receive the dnockout press in addition when the drawing of patterns to the suppression quality of pressed compact has been guaranteed.

Description

A kind of drop hammer type powder pressing device
Technical field
The utility model relates to the powder pressing device of field of powder metallurgy, particularly relates to a kind of drop hammer type powder pressing device.
Background technology
Powder metallurgy is the main method producing the work materials such as high performance structures material, cermet, special type function material, in order to the sintered article obtained, must accomplish the even density distribution of powder in compressing process, the compressing of current powder has electromagnetism compacting, compacting etc. of dropping hammer.Wherein drop hammer in pressure setting, drop hammer and to separate with drift, knock drift by the freely falling body dropped hammer and by the powder pressing forming in die.But because die is as a whole, when after powder pressing forming, during the demoulding, need to be ejected by the pressed compact in die by miscellaneous equipment, this not only makes the demoulding inconvenience of pressed compact, and pressed compact also easily affects its Forming Quality by after knockout press.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pressed compact and is convenient in demoulding and the drop hammer type powder pressing device that can ensure to suppress quality.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of drop hammer type powder pressing device, comprise drop hammer, drift, cushion block and the die for powder filler, described cushion block has been wholely set locating convex block, described die case is on described locating convex block, described die forms by half-open left die and right die, overcoat is arranged with outside described die, described drift stretches in described die, and powder is filled between described locating convex block and described drift.
Described drift is fixedly installed force-transmitting block.
Described force-transmitting block is fixedly connected with by screw with described drift, and due to drift being provided with force-transmitting block, and both are detachable, thus greatly can reduce the volume of drift, when drift wearing and tearing need to change, reduces cost.
The upper end of described die is provided with locating hole, and described force-transmitting block stretches in described locating hole, achieves the location to force-transmitting block, prevents force-transmitting block from shaking in pressing process and affecting compacting quality.
Compared with prior art, the utility model has the advantages that because die forms by half-open left die and right die, when after powder pressing forming, take away overcoat, left die and right die are separated in half and just pressed compact can be taken out, this not only facilitates the demoulding of pressed compact, and makes pressed compact when the demoulding not by knockout press, thus ensure that the compacting quality of pressed compact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in the figure, a kind of drop hammer type powder pressing device, comprise drop hammer 1, drift 2, cushion block 3 and the die for powder filler 4, die forms by half-open left die 5 and right die 6, cushion block 3 is wholely set locating convex block 31, die case is on locating convex block 31, overcoat 7 is arranged with outside die, drift 2 stretches in die, powder 4 is filled between locating convex block 31 and drift 2, drift 2 is fixedly connected with force-transmitting block 8 by screw, and the upper end of die is provided with locating hole 9, and force-transmitting block 8 stretches in locating hole 9.
