Forming die and forming method for blade with multi-powder structure in circumferential direction

Abstract

The forming die comprises a die body, a first upper punch, a second upper punch, an outer lower punch, an inner lower punch and an installation die frame, the die body is installed on the installation die frame and can move up and down, a die cavity is formed in the die body, and the first upper punch, the second upper punch, the outer lower punch, the inner lower punch and the installation die frame are arranged in the die cavity. The first upper punch, the second upper punch, the outer lower punch and the inner lower punch can move up and down to enter or leave the die cavity, and the first upper punch, the outer lower punch, the inner lower punch and the die cavity are matched to achieve forming of the first circumferential base body and the center base body which are provided with the multi-powder structure blades in the circumferential direction. The second upper punch, the outer lower punch, the inner lower punch, the die cavity, the first circumferential base body and the center base body are matched to achieve forming of the second circumferential base body with the multi-powder structure blade in the circumferential direction, and the forming method comprises the steps of first-time filling, first-time pressing, first-time demolding, second-time filling, second-time pressing, second-time demolding and the like. The method has the advantages of being good in forming quality, high in applicability, convenient to operate and the like.

Description

technical field [0001] The invention mainly relates to the field of forming of metal cutting tools, in particular to a forming mold and a forming method of inserts with multi-powder structure in the circumferential direction. Background technique [0002] In powder metallurgy technology, the powder forming process is the most important process in the production of CNC blades. Generally, a device consisting of a mold body and upper and lower punches is used for powder forming, but the structure of the product formed by this device is relatively simple, and it can only be used for cutting blades with a single substrate, and cannot achieve wear resistance and impact resistance at the same time. Resulting in insufficient blade performance. Therefore conventional molding devices and presses cannot realize its molding requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, to...
