Abstract

The invention discloses a boiler header pipe hole machining tool, relates to a pipe hole machining tool, and aims to solve the problems of time waste due to need of triple machining, need of frequent replacement of a cutter bar and a blade, incapability of guaranteeing the pipe hole size precision in manual operation and difficult guarantee of the pipe hole size requirements in pipe hole machining in traditional boiler head pipe hole machining. The boiler header pipe hole machining tool comprises a bolt, a guide sleeve, a blade, a cutter bar, blade ejecting screws and two guide sleeve fixed screws; the cutter bar includes a flat section, a conical section, a blade mounting section and a guide sleeve fixed section; the flat section, the conical section, the blade mounting section and the guide sleeve fixed section are fixedly connected in sequence; a plane and a blade mounting hole are machined on the blade mounting section; blade ejecting screw thread holes are formed from the plane to the blade mounting hole; the guide sleeve coats the guide sleeve fixed section; the blade is mounted in the blade mounting hole; and the blade ejecting screws are arranged in the blade ejecting screw thread holes. The boiler header pipe hole machining tool is used for header pipe hole machining.

Description

technical field [0001] The invention relates to a pipe hole processing tool, in particular to a boiler header pipe hole processing tool. Background technique [0002] In boiler manufacturing, the header is its main component. At present, most of the tube holes in the header manufacturing of 300MW, 600MW and other large-capacity boilers are made by first processing the A size with a drill, and then processing the B size separately with different white steel knives. , C size. This method needs to be processed three times, and the tool holder and blade need to be replaced frequently. It is a waste of time, and when using a white steel knife (aspect, long strip) to process the dimensions B and C, it is necessary to grind the dimensions of the B and C shapes according to the drawing size. Since the material of the white steel knife is relatively hard, it is time-consuming and laborious to grind , and manual operation cannot guarantee the dimensional deviation, it is difficult t...
