Self guiding type mechanical powder product finishing machine

Abstract

The invention discloses a self guiding type mechanical powder product finishing machine. An upper slide block of the finishing machine does up and down reciprocating movement via a guide rail arranged on a machine frame through being driven by a crank shaft, an upper connecting plate is connected with the bottom of the upper slide block, an upper punching fixed plate is arranged under the upper connecting plate, a middle mold is arranged under the upper punching fixed plate and is connected with a work table of the machine frame, the middle part of the middle mold is provided with a hole, a core rod is arranged in the middle part of the upper connecting plate and passes through an upper punching inner hole arranged under the upper punching fixed plate, a guide post is arranged at the bottom of the upper connecting plate and passes through the upper punching fixed plate and the middle mold, an upper punching fixed plate reset spring is surrounded on the periphery of the guide post, a female mold cover with a hole formed in the middle part is fixedly connected with the middle part of the middle mold, the hole formed in the middle part of the female mold cover corresponds to the hole at the middle part of the middle mold, a female mold is arranged in the hole of the middle part of the female mold cover, a lower punching device is arranged in the hole of the middle mold and passes through the female mold, and a pressure regulation screw rod is arranged at the bottom of the middle mold and is used for regulating the height of the lower punching device. Compared with the existing structure, the structure of the invention is simpler, and the invention is particularly suitable for finishing ball type products.

Description

technical field [0001] The invention relates to powder metallurgy finishing equipment, which is a mechanical self-guiding powder product finishing machine. Background technique [0002] The finishing of powder metallurgy products refers to placing the product in the female mold, applying pressure to the product by punching up and down, then removing the pressure, and then coming out of the female mold to become a product that meets the design requirements. The structure of the widely used finishing machine is as follows: the power source is an electric motor, which drives the transmission wheel to rotate through the V-belt, and then drives the flywheel to rotate through the bridge wheel. The flywheel drives the eccentric crankshaft to rotate, and the crankshaft drives the upper slider to reciprocate up and down. The frame is installed on the middle template and the upper slider, the upper template is fixed on the upper slider, the upper punch is fixed on the upper punch fixi...
