Embodiment Construction

[0010] The invention provides a special wear-resistant material for screw nuts, which uses ordinary gray cast iron as the base material, and then adds some alloy elements, non-ferrous metals (including 10% copper, 10% Ductile iron element; 6% Cr chromium steel element; 2% Ni nickel element), and adjust the original pouring process, add the proportioning alloy to the cast iron after the cast iron is melted, and start pouring after it is fully melted.

Abstract

The invention relates to the field of forging material, in particular to a lead screw-nut wear-resistant special material. The invention provides the lead screw-nut wear-resistant special material which takes common grey cast iron as base material; then, before pouring, alloying elements and non-ferrous metal (including 10% of Cu element, 10% of ductile iron element, 6% of Cr steel element and 2% of Ni element) are added into the base material; and the original pouring technology is adjusted, the proportional alloy is added into cast iron after the cast iron is melted, and pouring is carried out after the cast iron is fully melted.

Description

[0001] technical field [0002] The invention relates to the field of forging materials, in particular to a special wear-resistant material for screw nuts. Background technique [0003] At present, in the field of mechanical processing equipment, the most commonly used reciprocating parts of screw nuts are mostly copper materials and cast steel materials. Due to the non-stop reciprocating movement of this moving part every day, the accuracy of the sliding surface begins to change for as short as half a year and as long as one year. Roughness also varies. The precision of the processed mechanical parts is seriously affected and cannot meet the high precision requirements. Parts with high machining accuracy must be replaced with screw nuts. This has brought great trouble and loss to customers in the machinery industry. How to solve the problem of screw nut wear is a technical problem that has not been solved in the machinery industry for many years. Contents of the i...
