Embodiment Construction

[0031] The weight lifting mechanism consists of a lifting member frame 2 with a through hole and a sensor sleeve 24 embedded in the through hole, four spring sleeves 11 and spring sleeve fasteners 13 arranged symmetrically, symmetrical and parallel to the axis of the moving direction. Arranged hydraulic piston cylinder 15; their connection relationship is as follows: the spring sleeve 11 is fixed on the lifting frame frame 2 through the spring sleeve fastener 13, and the piston rod of the hydraulic piston cylinder 15 and the two sides of the lifting piece frame 2 are arranged symmetrically. The ends are fixed by threads; the lifter frame 2 is welded by two front and rear parallel rectangular steel plates and ribs, and the middle space can accommodate the lug 19 of the hammer handle lock release mechanism. The sensor sleeve 24 is custom made to the specifications and dimensions of the pivot pin sensor 12 .

[0032] The hammer handle lock release mechanism is composed of a lock ...

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...
