Description
Technical Field
[0001] The utility model relates to the technical field of forging drilling, in particular to a drilling device for deep-sea oil production forging processing. Background Art
[0002] Deep-sea oil forgings refer to various forged parts used in the process of deep-sea oil extraction. These forgings usually need to withstand harsh working conditions such as high pressure, high temperature, corrosion, etc., so their performance and quality requirements are very high. Deep-sea oil forgings mainly include the following components: Drilling platform structural parts: such as the main structure, support frame, stairs, platform plates, etc. of the drilling platform, Christmas trees and accessories: including the Christmas tree body, valves, flanges, elbows and tees, etc., Oil pipes and casings: Pipelines used to transport oil and natural gas need to have high strength, corrosion resistance and sealing, Drill pipes and drill collars: Components used to transmit power and support the drill bit during drilling, which need to have high strength and wear resistance. When processing forgings, it is usually necessary to use a drilling device to drill holes in them to enhance their mechanical properties.
[0003] In the prior art, when drilling holes in deep-sea oil production forgings, the drilling device usually adopts a fixed drilling point design. When drilling holes in different positions is required, the position of the forging needs to be constantly adjusted, resulting in low drilling efficiency. In addition, since the drill bit is a consumable item, the drill bit needs to be replaced frequently. The existing drill bit is replaced by directly fixing the drill bit on the rotating shaft with bolts, and the bolts are usually located on one side of the rotating shaft. However, this operation may cause the center of the rotating shaft to be unstable, resulting in inaccurate drilling, and drilling may cause burrs or uneven areas on the surface of the forging. The existing drilling device cannot grind the forging. Therefore, in view of the above problems, a drilling device for deep-sea oil production forging processing is proposed. Utility Model Content
