Discharge mechanism of powder metallurgy press

Abstract

The invention discloses a discharge mechanism of a powder metallurgy press. The powder metallurgy press comprises a material hole main body, an upper pressing head, a lower pressing head and a return plate; the return plate is provided with a plurality of die cavities penetrating the upper and lower surfaces; the discharge mechanism of the powder metallurgy press comprises a forward push piece, a discharge box and a plurality of elastic elements, wherein the discharge box is arranged on the return plate in a sliding mode, and the front end of the discharge box is provided with an open accommodating groove; one end of each elastic element presses against the discharge box, and the other end of each elastic element presses against the return plate; and the forward push piece is arranged on one side of the material hole main body, can push a workpiece into the accommodating groove together with movement of the material hole main body, and continuously pushes the workpiece so that the discharge box leaves the die cavities. The discharge mechanism of the powder metallurgy press has the advantages that the discharged workpieces can be regularly sequenced, the sequenced workpieces are conveniently grabbed by a manipulator, and the grabbing efficiency of the manipulator is improved.

Description

technical field [0001] The invention relates to powder metallurgy equipment, in particular to a discharge mechanism for a powder metallurgy press capable of lining up discharged workpieces in an orderly manner to facilitate grabbing by a manipulator and increasing the grabbing frequency of the manipulator. Background technique [0002] In the powder metallurgy process, the alloy powder is compacted into a solid state in the mold cavity of a large-tonnage press, and then it needs to be taken out and placed on a sintering plate for sintering to form a finished product. The traditional process is that the workpiece that has been compacted into a solid body is lifted up under the mold of the press to reach the same height as the bottom of the cavity, and then it is pushed forward by the elastic rubber on the front side of the cavity or taken away by the CNC manipulator. . However, due to the close fit between the compacted workpiece and the lower pressure head, the peripheral p...

Problems solved by technology

However, the improved method also brings some disadvantages, that is, after the workpiece is pushed by the elastic rubber on the front side of the cavity, the original neat and orderly posture in the mold cavity is changed into a messy and disorderly posture. It is difficult for the manipulator to accurately grab the material, which has a great impact on the unloading, and there is no solution to eliminate the above impact
