Auxiliary rubbing and screening machine for compression production of round-flat slitters

Abstract

The invention discloses an auxiliary rubbing and screening machine for compression production of round-flat slitters. The auxiliary rubbing and screening machine comprises a support, a trough is fixed on the support and is rectangular, a plurality of round through holes with the diameter being 0.18 mm are evenly distributed in the surface of the trough, and the circle center distance between every two adjacent round through holes is 1 mm; a sliding push block matched with the trough is arranged in the trough, and the width of the sliding push block is consistent with the internal width of the trough; a driving device is fixed at one end of the trough, and the driving end of the driving device is connected with the sliding push block; and a conveyor belt is arranged below the trough, moves in the long axis direction of the trough and penetrates through the bottom of the support. By means of the auxiliary rubbing and screening machine for compression production of the round-flat slitters, the problems in the prior art can be solved, rubbing and screening of raw materials for compression of the round-flat slitters are achieved, the grain size of the raw materials is improved, and the purpose that the compressed round-flat slitters have the good metallographic phase is achieved.

Description

technical field [0001] The invention relates to the field of disc knife production, in particular to an auxiliary sieve cleaning machine used for pressing production of 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...

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
