Gear tooth type powder metallurgy part surface extrusion machining die

Abstract

The invention discloses a gear tooth type powder metallurgy part surface extrusion machining die which comprises a cross beam, stand columns, a rack, supporting legs, an adjustable pipe, an adjustable bolt, an upper die, a die extrusion hydraulic rod, a lower die, a part body and a control panel, wherein the stand columns are connected to the left side and the right side of the lower portion of the cross beam through bolts; the longitudinal lower ends of the stand columns are in bolted connection with the middle parts of the left and right sides of the upper part of the rack; and supporting legs are connected to the four corners of the bottom of the rack through bolts. By arranging the movable clamping seat, the movable pipe, the supporting screw rod, the movable nut, the buffer spring, the movable clamping seat and the through hole, a part body is arranged between the movable clamping seat and the movable clamping seat, and then the movable nut is adjusted to move on the outer wall of the supporting screw rod, so that the movable clamping seat moves until the part body is clamped, and stable machining operation can be conducted, and the buffering stability is guaranteed through the buffering springs.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a die for extrusion processing of the surface of gear tooth powder metallurgy parts. Background technique [0002] With the development of the automobile industry, densified powder metallurgy teeth and sprockets are more and more widely used in engines due to their high strength and high load characteristics. [0003] In the current extrusion die design, the dimensions of the die cavity are gradually reduced to the target size along the same angle. When the part passes through the die cavity under the action of the upper die, the plastic deformation of the part at each moment Both are the same as △d, so a surface extrusion die for gear tooth powder metallurgy parts is needed in production and processing. [0004] However, the existing extrusion dies still have the problems of not having the function of flushing debris, being unable to fixedly clamp parts of...
