Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] The embodiment of the present invention discloses a production process of the base body of the coiled pipe drill pipe. The pipe body is made by cutting the steel plate and coiling the pipe, which has high processing efficiency and low loss, and welds both the inside and outside of the pipe to avoid the problem of open welding; In addition, the concentricity of the diamond thin-walled drill base is improved by rounding the tube body, and a bevel is opened...

Abstract

The invention discloses a production process of a coiled pipe drill rod matrix. The coiled pipe drill rod matrix is applied to a thin-wall drill. The production process comprises the steps of 1, processing a pipe body, specifically, the operations of a, lofting and blanking, b, pipe coiling, c, welding of the coiled pipe, d, rounding and e, beveling are carried out; 2, welding the pipe body and ajoint disc; 3, assembling a joint and the joint disc; and 4, turning a welding opening. Therefore, the production and processing efficiency of the coiled pipe drill rod matrix is improved, the loss isreduced, and the processing yield is improved and the service life is prolonged while the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of thin-wall drill manufacturing, in particular to a production process of a coiled pipe drill rod base body. Background technique [0002] Diamond thin-walled drills, also known as water drills and hollow drills, are widely used for drilling and sampling non-metallic hard and brittle materials such as reinforced concrete, concrete, cement, asphalt roads, glass, stone, hard masonry, etc. It is used for wall drilling in building construction, house renovation, pipeline laying and municipal construction, and can also be used for sampling by construction quality supervision units. It is one of the indispensable consumable tools for engineering construction. [0003] Usually, the diamond thin-walled drill bit is composed of a diamond drill bit and a drill pipe matrix. In the prior art, the machining of the drill pipe matrix is ​​generally to directly process the thick-walled pipe with a wall thickness of 9mm to ...
