Y-shaped wear-resistant glasses plate and manufacturing method

Abstract

The invention discloses a Y-shaped wear-resistant eyeglass sheet, which comprises an eyeglass sheet body and a hard alloy wear-resistant layer, wherein the hard alloy wear-resistant layer is on the working face of the eyeglass sheet body; hard alloy blocks are welded on the hard alloy wear-resistant layer; a fit clearance between each two adjacent hard alloy blocks is a Y-shaped clearance; and welding flux is filled in each Y-shaped clearance. The Y-shaped wear-resistant eyeglass sheet disclosed by the invention has the advantages that the overall wear-resisting property of the eyeglass sheet and the hardness of the working face are improved, and the phenomenon that a hard alloy layer is cracked due to the fact that the hard alloy layer is extruded due to the fact that body materials are different in expansion and shrinkage coefficient when integral hard alloy layer welding is performed is avoided, so that the service life of the Y-shaped wear-resistant eyeglass sheet is prolonged.

Description

technical field [0001] The invention relates to accessories for concrete conveying equipment, in particular to spectacle plates for concrete conveying pumps and a manufacturing method. Background technique [0002] The spectacle plate is used to protect the port of the S pipe and is a wear-resistant part. It is an important vulnerable part of the concrete pump. Its service life is related to the overall performance of the cement pump. During use, it The form of damage is mainly the interaction between the spectacle plate and the cutting ring. When the concrete stone is sheared, because the hard alloy wear-resistant layer does not disperse the impact force, the hard alloy ring collapses, especially the spectacle plate. The bridge of the nose will break and fall quickly, resulting in a short service life of the glasses plate. [0003] In the prior art, the hard alloy wear-resistant layer is formed by overall surfacing welding, but the wear-resistant wear-resistant layer of th...

[0002] The spectacle plate is used to protect the port of the S pipe and is a wear-resistant part. It is an important vulnerable part of the concrete pump. Its service life is related to the overall performance of the cement pump. During use, it The form of damage is mainly the interaction between the spectacle plate and the cutting ring. When the concrete stone is sheared, because the hard alloy wear-resistant layer does not disperse the impact force, the hard alloy ring collapses, especially the spectacle plate. The bridge of the nose will break and fall quickly, resulting in a short service life of the glasses plate

[0003] In the prior art, the hard alloy wear-resistant layer is formed by overall surfacing welding, but the wear-resistant wear-resistant layer of the surfacing welding layer is not ideal in terms of wear resistance and hardness compared with the cemented carbide block, especially when the concrete stone is sheared. , easy to cause cracking and low service life

Using the method of integral hard alloy ring, the integral hard alloy ring improves the wear resistance and impact resistance of the working surface of the spectacle plate. However, the thermal expansion and contraction coefficients of the hard alloy ring and the spectacle plate body are different during processing, resulting in hard The alloy ring cracks, and when the stone is sheared, there is no effective buffer to cause fracture
