Abstract
The invention discloses a bar stock pressing mold, which comprises an upper mold, a lower mold and a female mold, and is characterized in that each of the upper mold and the lower mold comprises a fixing seat, a pressing rod and a pressing head; the pressing heads of the upper mold and the lower mold have the same diameter; the female mold comprises a fixing seat and a female mold body; a cylindrical mold hole is formed in the female mold body; and the distances between the wall of the female mold and the upper mold as well as the lower mold are 0.3 to 0.5 mm after the upper mold and the lower mold are sleeved in the female mold. The bar stock pressing mold can ensure the quality of a pressed product and is convenient in demoulding during pressing of the bar stock product, and cannot cause seizure. Due to the adoption of a hard alloy sleeve, the service life can be prolonged and the processing cost can reduced. The pressed product is attractive and is prevented from being broken in edges and corners.
Description
Technical field
The present invention relates to a kind of the graininess powder is pressed into the compacting tool set of bar, especially for the straw particle.
Background technology
The graininess powder is pressed into bar, need with the graininess powder in die through upper and lower mould pressurize simultaneously the compacting form.Gap between existing compacting tool set upper and lower mould and the die is less, upper and lower mould takes place in the pressing process easily kill the situation in die.If strengthen the gap between upper and lower mould and the die, because the compacting raw material is the uneven powder of particle, existing particle has the powder of comprising, and pulverous raw material can be embedded into again in the gap between upper and lower mould and the die and goes to make upper and lower mould to kill.Therefore, the gap between upper and lower mould and the die is provided with and need guarantees the well demoulding, the type quality of the product that can guarantee again to suppress.
Summary of the invention
The object of the invention is to the defective of prior art a kind of compacting tool set that is used for the graininess powder is pressed into bar to be provided, especially for the bar compacting tool set of straw particle.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
A kind of bar compacting tool set comprises upper die and lower die and die, it is characterized in that: said upper die and lower die comprise holder, depression bar and pressure head, and said patrix is identical with counterdie pressure head diameter; Said die comprises holder and die body, and said die body is provided with cylindrical nib; Said patrix and lower die-sleeve in die the back and the die wall between spacing be 0.3-0.5mm.This spacing can guarantee that the compacted products quality is simultaneously conveniently stripped, can not cause mould to kill.
It is further characterized in that: said cylindrical nib is arranged in the carbide alloy cover, and said carbide alloy cover is embedded in the said die body.Owing to adopted the nib of carbide alloy, make the life-span of die prolong greatly, outside simultaneously die body can adopt common steel, has practiced thrift material cost, has also reduced difficulty of processing.
A kind of bar compacting tool set according to claim 1 is characterized in that: said patrix and counterdie pressure head somewhat larger in diameter are in the depression bar diameter, and said pressure head head has the truncated cone-shaped pit that diameter is slightly less than the pressure head diameter.Adopt this kind structure to have only pressure head part contact with raw material with the die nib, the resistance when having reduced compacting, the product two ends that suppress that the truncated cone-shaped groove on the while pressure head is have chamfering, both attractive in appearance have can prevent the fragmentation of product corner.
Can either guarantee when the present invention suppresses the bar product that the compacted products quality is simultaneously conveniently stripped again, can not cause mould to kill.Adopt the carbide alloy cover can life-saving with cut down finished cost.The product of compacting had been both attractive in appearance to be had and can prevent that the product corner is broken.
Description of drawings
Fig. 1 is upper die and lower die of the present invention and die front elevational schematic;
Fig. 2 is upper die and lower die of the present invention and die schematic top plan view.
The specific embodiment
Like Fig. 1, a kind of bar compacting tool set shown in 2, comprise upper die and lower die and die, said upper die and lower die comprise holder 1, depression bar 2 and pressure head 3, said patrix is identical with counterdie pressure head diameter; Said die comprises die holder 4 and die body 5, and said die body 5 is provided with cylindrical nib; Said patrix and lower die-sleeve in die the back and the die wall between spacing be 0.3-0.5mm.Said cylindrical nib is arranged in the carbide alloy cover 6, and said carbide alloy cover 6 is embedded in the said die body 5.Said patrix and counterdie pressure head 3 somewhat larger in diameter are in depression bar 2 diameters, and said pressure head 3 heads have the truncated cone-shaped pit that diameter is slightly less than the pressure head diameter.
Lower die-sleeve is in die during work, and counterdie descends, and raw material flows into nib, and loose raw material fills up nib, and patrix presses down, and pushes up on the counterdie, and the raw material in the nib is collapsed into bar closely, lifts on the patrix, and counterdie upwards ejects, with the bar ejection device.
Claims (3)
