Abstract

The invention discloses a press for high-speed pressing of powder metallurgy on the basis of mechanical spring energy storage. The press comprises a press body frame, a heavy hammer lifting mechanism, a heavy hammer impact mechanism, a hammer handle locking and releasing mechanism, a mechanical spring, a suspension part thereof, a spring sleeve, a fastener thereof, an upper die punching and supporting table and a power mechanism, wherein the heavy hammer lifting mechanism sliding along a straight line, the hammer handle locking and releasing mechanism, the heavy hammer impact mechanism and the upper die punching and supporting table are successively connected on a guide rod in series; in the direction vertical to the guide rod, two ends of a shaft pin type sensor pass through and are clamped into the through holes of a suspension part frame; and the middle part passes through to be clamped in a hanger through hole. The high-speed press for powder metallurgy of the invention is suitable for producing powder metallurgy high-speed pressing parts with smaller volume, has small volume, small weight, simple structure, convenient assembly and reliable performance, overcomes the problems of complex structure and high manufacturing cost of the existing hydraulic high-speed pressing equipment, and is easy to popularize and apply in the powder metallurgy industry.

Description

technical field [0001] The invention relates to a powder metallurgy high-speed pressing equipment, in particular to a powder metallurgy high-speed pressing press based on mechanical spring energy storage. Background technique [0002] Powder metallurgy high-speed compaction technology (high velocity compaction, referred to as HVC) is a Swedish metallurgical powder manufacturer A new process and new technology of powder metallurgy jointly researched and developed by AB and equipment manufacturer Hydropulsor AB in 2001. Specifically, the powerful shock wave energy generated by the high-speed impact of the heavy hammer will densify the metal powder transferred to the mold through the die within 0.02s, and the additional shock waves at intervals of 0.3s can continuously increase the density, so that The material performance is more excellent. Compared with the traditional powder pressing technology (such as warm pressing and isostatic pressing), this process is especially suit...
