Description

Technical Field

[0001] This utility model relates to the field of forging press technology, specifically a metal powder forging press with protection on both sides. Background Technology

[0002] Metal powder forging press is a device that puts metal powder (or preform) into a mold and densifies it under extremely high unidirectional pressure to form a high-performance part that is close to the final shape.

[0003] Existing metal powder forging presses have an open processing area on all sides. If it has a structure with two lifting plates, the lower lifting plate needs to be controlled by a hydraulic cylinder. However, the hydraulic cylinders controlling the lower lifting plate are located on both sides of the equipment. Since the processing area is not shielded, tiny metal powder particles may come into contact with the piston rods of the hydraulic cylinders on both sides, which reduces the service life of the hydraulic cylinders and poses certain safety hazards.
