Abstract

The invention discloses a pipe opening device and a hole opening method. The pipe opening device comprises a bottom plate, a positioning boss and a punching rod, wherein the bottom plate, the positioning boss and the punching rod are mounted on a machine tool workbench, a groove is formed in the bottom plate, the bottom of the positioning boss is matched with the groove to be installed on the bottom plate, and a first through hole is formed in the middle of the positioning boss; a positioning adjusting plate is fixed to the front side of the positioning boss through a bolt A, a second throughhole is formed in the positioning adjusting plate, and an adjusting bolt is also in threaded connection with the positioning adjusting plate; and the pipe opening device comprises a positioning pad, the positioning pad is arranged on the front side of the positioning adjusting plate, a third through hole is formed in the positioning pad, the punching rod penetrates through the first through hole,the second through hole and the third through hole, a punching groove is further formed in the positioning pad, and the punching groove is in communication with the third through hole. The pipe opening device has the advantages that the pipe is accurate in positioning and high in stability, and the positioning adjusting plate can be adjusted to be suitable for pipes with different lengths.

Description

technical field [0001] The invention relates to the field of drilling devices, in particular to a pipe drilling device and a drilling method. Background technique [0002] A steel pipe is a steel product with openings at both ends and a hollow section, and the ratio of its length to the perimeter of the section is large. When the ratio of the length to the perimeter of the section is small, it can be called a pipe section or a tubular fitting, which belongs to the category of pipe fittings. Among them, stainless steel pipes are A hollow, elongated round steel material that is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. Modern production is inseparable from steel pipes, and steel pipes often need to be drilled during installation or connection. Steel pipe drilling is one of the common processes in steel pipe processing. [0003] The perforating device of the...
