Description

Technical Field

[0001] The utility model relates to the field of drill rod processing and testing, in particular to a drill rod outer surface rolling tool for mining. Background Art

[0002] In the manufacturing and application of mining drill pipes, ensuring the operating efficiency, safety and durability of drill pipes has always been the focus of the industry. Especially in underground working environments, drill pipes need to be accurately guided, drill efficiently, and be able to withstand complex formation pressure and impact. For this reason, the chamfer design of the drill pipe surface is particularly important.

[0003] Chamfer design is not only related to the guidance of the drill pipe, so that it can move accurately along the predetermined path, but also directly affects the friction between the drill pipe and the hole wall. Appropriate chamfer design can significantly reduce friction and energy loss, thereby improving drilling efficiency. At the same time, a reasonable chamfer design can also enhance the structural strength of the drill pipe, so that it can maintain good working performance when subjected to complex external forces such as formation resistance, vibration and torsion. However, in order to ensure that the chamfer design can achieve the expected effect, the pressure of the chamfer on the surface of the drill pipe must be tested. This test step is of great significance for verifying the rationality of the chamfer design and ensuring the quality and performance of the drill pipe. By testing the chamfer pressure, it can be ensured that the chamfer design meets the guidance requirements, reduces friction loss, improves drilling efficiency, and verifies whether the structural strength of the drill pipe meets the design requirements.

[0004] Therefore, the utility model aims to provide a tool for rolling the outer surface of a mining drill rod, which provides strong support for optimizing the drill rod design, production process and quality control by accurately measuring the chamfering pressure. Utility Model Content
