Tool manufacturing method special for radiant tube machining

Abstract

The invention discloses a tool manufacturing method special for radiant tube machining. The manufacturing method includes the step of manufacturing a positioning mechanism and the step of manufacturing a cutting knife mechanism. In the step of manufacturing the positioning mechanism, a V-shaped base is fixed to a bottom plate through a fastening bolt, a rotating pressing plate is arranged on the V-shaped base, one side of the rotating pressing plate is connected with the V-shaped base through a rotating pin, and the other side of the rotating pressing plate is connected with the V-shaped base through a bolt and a nut. In the step of manufacturing the cutting knife mechanism, a knife sleeve is manufactured, welding grooves which are symmetrical and matched with tool bits are formed in the start end of the knife sleeve, knife sleeve rotation prevention plates are fixedly arranged on the two side faces of the tail end of the knife sleeve respectively, the tool bits are fixedly arranged on the welding grooves of the knife sleeve, a cutting knife connecting piece is manufactured, one end of the connecting piece is a cone, the other end of the connecting piece is a cylinder, the large end of the cone is connected with one end of the cylinder, the other end of the cylinder is connected with the tail end of the knife sleeve through a fastening screw, and the cylinder is sleeved with a thread bushing and matched with the thread bushing in a threaded mode. A tool manufactured through the method is simple in structure, convenient to use, high in accuracy and capable of meeting the requirement for mass production, and the efficiency can be improved by more than 5 times.

Description

[0001] technical field [0002] The invention belongs to a manufacturing method of a hole processing device, and in particular relates to a manufacturing method of a special frock for radiant tube processing. [0003] Background technique [0004] The transverse holes on the wall of the metallurgical radiant tube are hard and sticky, and the hole size is large, making it difficult to process. When processing holes on a small horizontal boring machine, it needs to be drilled in one step and reamed in 3 to 4 steps before it can be completed. However, multiple tool changes and repeated cutting are required during the processing, and the processing time is as long as 50 minutes, resulting in low production efficiency. And the strength of the boring head of the horizontal boring machine is insufficient, and the effect is not good enough when used on the horizontal boring machine. [0005] Contents of the invention [0006] In order to overcome the above-mentioned problems e...
