Problems solved by technology

However, the existing semi-finished disc cutter is difficult to press and form. Because the semi-finished product has a large diameter and is too thin, when using pellets to press, the semi-finished product has a poor density, and the product is not easy to place on the plate. The metallographic appearance of the product cannot be guaranteed.
If powder is used for pressing, the fluidity of the powder is poor, which will easily lead to uneven pressing and charging, resulting in large deformation of the product after sintering
Therefore, for the production of disc knife in the prior art, its scrap rate is very high, and waste is very big

Abstract

The invention discloses an upstream auxiliary tool for round-flat slitter pressing. The upstream auxiliary tool for round-flat slitter pressing comprises a feeding opening; a screening net with 20 meshes is arranged on the feeding opening; the feeding opening communicates with a stirring cabin; a stirring device is arranged inside the stirring cabin; a vibrating screen is arranged below a discharging end of the stirring cabin; the vibrating screen is provided with three layers of screening nets; the mesh numbers of the three layers of the screening nets are 40 meshes, 60 meshes, and 80 meshes in sequence from top to bottom; and a material receiving device is arranged below the vibrating screen. According to the upstream auxiliary tool for round-flat slitter pressing provided by the invention, the purpose that the defective rate of the round-flat slitter is reduced is achieved.

Description

technical field [0001] The invention relates to the field of disc knife production, in particular to an upstream auxiliary tool for pressing the disc knife. Background technique [0002] Disc knives, also known as disc knives, are often used in grinding, cutting and other work in the mechanical field, and have a wide market. In the existing wafer cutter production process, pellets or powder are used to press into semi-finished wafers, and then sintered at high temperature to achieve consolidation and molding. However, the existing semi-finished products are difficult to press and form. Because the semi-finished products have a large diameter and are too thin, when using pellets to press, the semi-finished products have poor density, and the products are not easy to be placed on the plate, and the metallographic appearance of the products cannot be guaranteed. If powder is used for pressing, the fluidity of the powder is poor, which will easily lead to uneven pressing and ch...
