Abstract

The invention provides a novel heavy cutter ring and a production process thereof, and relates to the field of machining. The novel heavy cutter ring comprises a protective ring, splicing plates, fixing columns, fixing rings and reinforcing rings, wherein the protective ring is made of a wear-resistant material; mounting grooves which are distributed at equal intervals around the central axis of the protective ring are formed in the outer wall of the protective ring; triangular abutting blocks are fixedly connected to the positions, close to the mounting grooves, of the outer wall of the protective ring; the radian of the outer wall of one end of each splicing plate is matched with the inner wall of the protective ring; one end of each splicing plate is fixedly connected with the inner wall of the protective ring; the multiple splicing plates which are annularly distributed form the middle part of the cutter ring; the section of each splicing plate is similar to an isosceles trapezoid; a first fixing groove is formed in the outer wall of the other end of the protective ring; and the outer wall of the other end of each splicing plate is fixedly connected with the outer wall of the corresponding fixing ring. According to the novel heavy cutter ring and the production process thereof, the maintenance cost is reduced, and the maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a novel heavy-duty cutter ring and its production process. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield tunneling machine is to construct the "shield" (referring to the supporting segment) of the tunnel while the tunnel boring machine is excavating, which is different from the open construction method. [0003] Due to the large cutter ring used for the shield machine, it has high requirements for manufacturing molds and manufacturing processes, and the integrated cutter ring is easy to cause wear during long-term use, and it is difficult to adjust the cutter head. It is troublesome to overhaul and replace the cutter ring, and the maintenance cost is relatively high, so a new type of heavy duty cutter ring is needed. Contents of the invention [0004] (1) Solved techni...
