Automatic clamping and feeding device for powdered metallurgical parts

Abstract

The invention discloses an automatic clamping and feeding device for powdered metallurgical parts, which comprises a rack and a workbench, wherein the workbench is provided with a female die assembly, the female die assembly comprises a female die plate, an upper female die, a clamping mechanism, a transverse driving device and a longitudinal driving device, the clamping mechanism is used for feeding, the transverse driving device is used for driving the clamping mechanism to realize an open-close motion, and the longitudinal driving device is used for driving the clamping device to realize a feeding motion; the clamping mechanism comprises a left clamping fixed plate and a right clamping fixed plate which are respectively symmetrically arranged on both sides of the upper female die and perpendicular to the workbench, and a gap is formed among the lower surfaces of the left and right clamping fixed plates and the workbench; and a plurality of left clamping blocks are uniformly arranged on the inner side of the left clamping fixed plate at a certain interval, and a plurality of right clamping blocks which are matched with the left clamping blocks and used for clamping powdered metallurgical parts are correspondingly arranged on the inner side of the right clamping fixed plate. The device is wider in applicable part size and higher in working efficiency.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to an automatic clamping and feeding device for powder metallurgy parts. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composites and various types of products. Due to the high precision requirements of powder metallurgy parts, after sintering, a press is needed to shape the shape of the parts. In order to avoid injury to the worker's hand when the powder metallurgy parts are shaped in the prior art and to prevent the press from being punched, the powder metallurgy parts are generally clamped by manipulators. However, the dimensions of the fingers of the manipulator are usually fixed, and it can only hold parts of a single size during its use. If the powder metallurgy parts have multiple sizes,...

AI Technical Summary

Problems solved by technology

However, the dimensions of the fingers of the manipulator are usually fixed, and it can only hold parts of a single size during its use. If the powder metallurgy parts have multiple sizes, it is necessary to replace multiple different manipulators for clamping. The replacement operation is cumbersome and the work efficiency is low
