Bionic coupling cast iron guide rail and manufacturing method thereof and regeneration method of waste machine tool guide rail

Abstract

The invention relates to a bionic cast iron guide rail and a manufacturing method of the bionic cast iron guide rail and a regeneration method of a waste machine tool guide rail. The cast iron guide rail is composed of a guide rail main body and a surface structure refining layer of the guide rail main body. Nanoscale martensite units are distributed on the surface structure refining layer. The manufacturing method of the cast iron guide rail and the regeneration method of the waste machine tool guide rail mainly comprise the following steps of obtaining the surface structure refining layer by using high-frequency electric pulses to process the guide rail, and manufacturing the nanoscale martensite units on the surface structure refining layer by the adoption of laser fusing method. The units and a guide rail parent together form a bionic coupling area which is soft and hard and resembles a living body structure, the units function as firm pile screws or reinforcing ribs which are additionally arranged on the surface layer of the guide rail, and parent materials surround the units and enable the unit to be connected into a whole so as to enable local peak values of the surface of the guide rail to be dispersed and stress of the guide rail to be even. The bionic cast iron guide rail has superior mechanic property and fatigue and abrasion resistant performance.

Description

technical field [0001] The invention belongs to the technical field of cast iron guide rails, and relates to a bionic coupling cast iron guide rail and a manufacturing method thereof, as well as a regeneration method for waste machine tool guide rails. Background technique [0002] In the machinery industry, machine tools are usually referred to as machine tools, which are the basic processing equipment in the machinery manufacturing industry. Its variety, performance, quality and technical level directly affect the performance, quality, production technology level and economics of other mechanical and electrical products. benefit. my country is the largest machine tool consumer market in the world. Currently, there are about 8 million machine tools. According to the internationally accepted reduction rate of 3%, about 250,000 old machine tools are eliminated every year, and the total metal weight exceeds 1.5 million tons. For an old machine tool, there are generally more t...

Problems solved by technology

The failure of machine tool guide rails is mostly due to fatigue wear failure. During the tens of thousands of reciprocating motions of the guide rail, under the pressure of the workpiece load, a certain arc will be generated and no longer maintain the level, so that the machining accuracy cannot be guaranteed; at the same time, during the use of the machine tool , Pitting corrosion will inevitably appear on the surface of the guide rail, which will also affect the machining accuracy of the machine tool and cause the machine tool to be scrapped
