Problems solved by technology

[0009] The automation degree of the traditional powder hydraulic molding machine is not high, the work efficiency is low, the energy consumption is large, the pressing procedure is too simple, the adjustment of the pressing process parameters is difficult, and the two-way pressing cannot be carried out. The density is inconsistent up and down, so it is difficult to adapt to high-demand products

Abstract

The invention relates to a full-automatic powder hydraulic forming machine which comprises a stander, a lower die, an upper die and a core die, and is characterized in that a die frame is arranged ona movable die frame rack and positioned between the upper and the lower dies; the movable die frame rack is driven to move up and down by a mold stripping oil cylinder; and an automatic material distribution mechanism is installed on the movable die frame rack and set to move up and down along with the movable die frame rack. The pressing technique adopts the way of pressurizing and exhausting fora plurality of times to lead powder to be gradually exhausted and compacted and simultaneously utilizes die frame floating technology to realize bidirectional pressurization of a green body in the processes of low pressure pressing, medium-pressure pressing and high pressure pressing, so that the frictional influence of the powder for the wall of the die frame can be reduced, the compactness at the upper and the lower parts of the green body can be consistent, and the quality of the green body is greatly improved.

Description

technical field [0001] The invention relates to the field of hydraulic forming machines, in particular to a fully automatic powder hydraulic forming machine and a pressing process thereof. Background technique [0002] Known, the powder hydraulic molding machine, its main structure includes: frame; lower mold, is arranged on the frame, and can be moved up and down by the cylinder of lower mold; The core mold is set in the lower mold and can be driven up and down by the core-pulling oil cylinder; the mold frame is fixedly arranged between the upper and lower molds; the automatic material distribution mechanism is installed on the frame and can perform material distribution to the mold cavity. [0003] The pressing process of traditional powder hydraulic molding machine is as follows: [0004] a. Automatic material distribution, so that the upper mold is in the upper position and the lower mold is in the lower position. Fill the powder into the mold cavity through the materia...
