Problems solved by technology

[0002] Traditional alloy rods used to make drill pipes are usually solid cylindrical, and the alloy rods need to be continuously cooled during the process of making drill pipes to increase the hardness of the drill pipes. However, the solid structure Alloy rods can only be cold-treated on the outer surface in the process of making and processing drill pipes, resulting in insufficient hardness of the drill pipes, which greatly reduces the service life of the drill pipes
In addition, due to the smooth surface of the ordinary solid cylindrical alloy bar, the drill pipe made of it is not easy to discharge waste chips during the operation process, which affects the operation progress and greatly reduces the work efficiency.

Embodiment Construction

[0009] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0010] refer to figure 1 As shown, a drill rod of the present invention includes a rod body 1 with a ventilation hole 2 inside, and the ventilation hole 2 has a helical structure. The outer surface of the rod body 1 is provided with threads 3 , and the threads are configured as helical grooves 4 .

[0011] When the rod body 1 is processed into a drill pipe, since the inside of the rod body 1 is provided with a ventilation hole 2, and it is of a helical structure, this s...

Abstract

The invention relates to a drill pipe bar material. At least one heliciform vent hole is formed in the drill pipe bar material, and a thread structure is also arranged on the outer surface of the drill pipe bar material. The drill pipe bar material can be machined into a drill pipe, when drill pipes of this type are used for drilling, an internal cooling mode is adopted, chipping removal speed and cooling speed are accelerated, the service life of the drill pipes is prolonged greatly, meanwhile, due to the fact that the thread structure is also arranged on the outer surfaces of the drill pipes manufactured by the drill pipe bar material, the drill pipes can generate backward discharging effects on chippings when the drill pipes carry out smash movements on the chippings, chipping removal capacity is improved greatly, and working efficiency is improved.

Description

technical field [0001] The invention relates to a rod, in particular to a drill rod for making a drill rod. Background technique [0002] Traditional alloy rods used to make drill pipes are usually solid cylindrical, and the alloy rods need to be continuously cooled during the process of making drill pipes to increase the hardness of the drill pipes. However, the solid structure Alloy rods can only be cold-treated on their outer surfaces in the process of making and processing drill pipes, resulting in insufficient hardness of the drill pipes and greatly reducing the service life of the drill pipes. In addition, due to the smooth surface of the ordinary solid cylindrical alloy bar, the drill pipe made of it is not easy to discharge waste chips during the operation process, which affects the operation progress and greatly reduces the work efficiency. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the pre...
