Abstract

The invention discloses a high-wear-resistant highway milling machine tool bit. The overall tool bit is composed of a tool handle and a tool body, an arc-shaped mounting groove is formed in the surface of the bottom end of the tool handle, and the tool body is mounted at the top of the tool handle. The invention further discloses a manufacturing process of the high-wear-resistant road milling machine tool bit, an alloy tool nose and a wear-resistant circular ring are made of hard alloy, and the tool handle, the tool body, a base plate, a heat dissipation flow guide groove and a mounting circular ring are of an integrated structure and are made of iron. According to the high-wear-resistant highway milling machine tool bit, the wear-resistant circular ring made of hard alloy material is welded to the blade body part, the wear progress of the tool body and the alloy tool nose portion of the tool bit is consistent due to the fact that the wear-resistant circular ring is worn before the tool body wears, the phenomenon that only the tool nose is wear-resisting but the service life of the tool body is short, the service life of the tool bit is greatly prolonged, the service life of the tool bit is prolonged from 8 hours to more than 16 hours, frequent replacement of the tool bit is avoided, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of milling machines, in particular to a high wear-resistant road milling machine cutter head and a manufacturing process thereof. Background technique [0002] Road milling machine is one of the main types of asphalt pavement maintenance construction machinery and one of the main equipment for asphalt concrete pavement maintenance construction. It can be used to remove defects such as pavement wrapping, oil waves, reticulation, ruts, etc. It can also be used to excavate road pits and grooves, as well as roughening of cement pavement and milling of surface layer dislocation. [0003] The milling rotor is the main working part of the milling machine. It is composed of the milling rotor shaft, the tool holder and the cutter head, etc. It directly contacts the road surface and works through its high-speed rotating milling cutter to achieve the purpose of milling. Among them, the cutter head directly collides wi...
