Automatic steel pipe chamfering machine

Abstract

A fully automatic steel pipe chamfering machine includes a base. A large carriage is installed on the base. Hook plates are installed on both ends of the base. The hook plates are hooked tightly on the base. A base box is installed on the large carriage through slide rails. The base The bedside box is installed on the box through fasteners. The bedside box has a combined structure and is divided into an upper box and a lower box. The lower box is connected to the base box. The upper box is installed on the lower box. The lower box is inside the box. A gear transmission mechanism is installed, and a main motor is installed on the base box located at the lower part of the bedside box. The output end of the main motor is connected to the gear transmission mechanism in the bedside box through a first coupling; a knife is installed on the outside of the bedside box. A cutting device is installed on the cutter head; a clamping device is installed at one end of the large carriage; a first-layer drag chain is also installed at one end of the large carriage, and a second drag chain is installed on the top of the first-layer drag chain through a splint. Layer drag chain. High level of automation, strong processing capability, safe and reliable.

Description

Technical field [0001] The invention relates to the technical field of steel pipe manufacturing, in particular to an automatic steel pipe chamfering machine applied to the manufacture of large-diameter straight seam and spiral submerged arc welded steel pipes. Background technique [0002] On the φ508-φ1422mm large-diameter straight seam, spiral submerged arc welded steel pipe production line, the chamfering machine is used to process the pipe end bevel and is one of the key equipment of the production line. For many years, the automation level and production efficiency of the chamfering machine are low. The end processing of the steel pipe depends on the manual control of the operator. The mold used for the steel pipe clamping needs to be replaced according to the specifications of the steel pipe. As the demand for large-diameter submerged arc welded pipes continues to increase, the range of steel pipe specifications is also expanding. At present, there are existing application...

AI Technical Summary

Problems solved by technology

At present, there are application requirements for steel pipes with a wall thickness of more than 50mm, but the processing capacity of the chamfering machine cannot meet the requirements at the same time. The main performance is that the cutting capacity of the chamfering machine is insufficient, and the structure and power of the chamfering machine need to be improved.

In terms of safety protection, when the chamfering machine cuts the pipe end, the iron filings are easy to fly out and hurt people. In general, the simple protection such as protective net cover or protective door can no longer meet the requirements of safety protection.
