Forming die and forming method for blade with multiple powder structures inside and outside

Abstract

The forming die comprises a die body, an outer upper punch, an inner 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 outer upper punch, the inner upper punch, the outer lower punch, the inner lower punch and the installation die frame are arranged in the die cavity. The outer upper punch, the inner upper punch, the outer lower punch and the inner lower punch can move up and down so as to enter or be away from the die cavity, and the inner upper punch, the outer lower punch and the inner lower punch are matched to achieve forming of the blade inner base body with the multiple powder structures inside and outside. The inner base body, the outer upper punch, the die cavity, the outer lower punch and the inner lower punch are matched to achieve forming of the blade outer base body with the multiple powder structures inside and outside, the forming method adopts the forming die, and the forming die and the forming method have 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 with inserts with multi-powder structure inside and outside. 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, provide a mold...
