Multifunctional cutting blade

Technical Field

The utility model belongs to the technical field of cutting tools, and relates to a multifunctional cutting blade for synchronously realizing ring cutting and chamfering of a large nodular cast iron pipe.

Background

In the production process of the nodular cast iron pipe, after the forming and annealing processes in the early stage are finished, the first finishing process is ring cutting, and the purpose of the process is to enable the sockets of the nodular cast iron pipe to be regular and enable the fixed length of the pipe body to be standardized. The next second procedure is chamfering, and the outer edge of the section of the end part of the pipe body at the ring cutting part is chamfered, so that the operation and the process execution are facilitated when the nodular cast iron pipe enters the subsequent procedures, and the later-stage installation of the finished nodular cast iron pipe is facilitated. Because the two stations are used in the actual operation process, the transportation process between the two working procedures is complicated and occupies a large amount of time during production in a streamline workshop, and the two stations are an important bottleneck link of the comprehensive operation rate. Therefore, it is necessary to design a cutting tool capable of cutting and chamfering simultaneously.
