Wiping and screening device for raw materials pressing disk cutters

Abstract

The invention discloses a wiping and screening device for raw materials pressing disk cutters. The wiping and screening device for the raw materials pressing the disk cutters comprises feeding ports which are each provided with a filter screen with the mesh number being 20; the feeding ports communicate with a stirring chamber which is internally provided with stirring devices; a rectangular groove is formed below the discharging end of the stirring chamber; a plurality of round through holes with the diameter being 0.18 mm are evenly distributed in the surface of the groove; the circle center distance between every two adjacent round through holes is 1 mm; a sliding material pushing block matched with the groove is arranged in the groove; the width of the sliding material pushing block is consistent with the inner width of the groove; a driving device is arranged at one end of the groove; the driving end of the driving device is connected with the sliding material pushing block; and a material receiving device is arranged below the groove. The wiping and screening device for the raw materials pressing the disk cutters aims at achieving the purposes that the raw materials for pressing the disk cutters are screened, and it is guaranteed that the pressed disk cutters have a good metallographic phase.

Description

technical field [0001] The invention relates to the field of disc knife production, in particular to a screening device for pressing raw materials with disc knives. 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 disc cutter is difficult to press and form. Because the disc cutter has a large diameter and is very thin, when pressing with pellets, the density of the semi-finished product is relatively poor, the product is not easy to be placed on the dish, and 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, re...

AI Technical Summary

Problems solved by technology

However, the existing disc cutter is difficult to press and form. Because the disc cutter has a large diameter and is very thin, when pressing with pellets, the density of the semi-finished product is poor, the product is not easy to place on the plate, and 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
