Abstract
Purpose. The purpose of this work is to study the patterns of wear and develop a technology for restoring the tail part of the cutter body of the road cutter. They conducted an analysis of the wear of the cutters and found that most of them are suitable for use, since the shape of the carbide tip has not changed much and can still be used for grinding asphalt-concrete mixture. Methodology/approach. The method of restoration of the caudal part of the body of the incisors was developed and proposed. The recovery route is as follows: 1. Cleaning the incisor. 2. Heating the tail part of the cutter with a propane-oxygen flame. 3. Plastic deformation of the cutter body in the die. 4. Air cooling. 5. Control measurement of size changes. The recommended heat treatment temperature for plastic deformation depends on the concentration of carbon and alloying elements of the steel, and lies in the temperature range from 800 to 1280°С, the heating time is 1.33 min. Before distribution, the body of the cutter was heated using a propane-oxygen flame. Deposition was carried out in a closed die with the help of a special Poisson. A cutter head was placed in the matrix, on which a guide with a punch was installed. The developed technology of restoration of the tail part of the incisor by handing. Findings. According to the proposed technology, the tail part of the cutter body is distributed from 0.04 mm to 0.73 mm per side. Research limitations/implications. In this way, the cutters of the road cutters are restored to almost the dimensions of a new part, which enables repeated use.
