Description

Technical Field

[0001] This utility model specifically relates to a flange opening assembly and opening device. Background Technology

[0002] A flange drilling device is a specialized piece of equipment used to machine various connection holes on flanges. It is widely used in the early processing stages of flange manufacturing and pipe and equipment connection. Its core function is to machine holes at specific locations on the flange that meet the requirements of size, precision, and distribution, according to design requirements, to ensure a precise connection between the flange and the pipe or equipment.

[0003] Existing equipment often employs manual marking and positioning of holes, requiring manual support of the flange and adjustment of the drill bit position for drilling. This method not only relies on the operator's experience but also involves a tedious marking and adjustment process, resulting in uneven hole angle intervals and affecting subsequent installation accuracy. For large flanges, manual drilling requires repeated verification, leading to low efficiency and extreme labor intensity. Furthermore, traditional equipment is mostly a fixed structure, making it difficult to adapt to the drilling requirements of flanges of different specifications, lacking the ability to automatically adjust hole spacing or accommodate flanges of various diameters, necessitating frequent tooling changes.

[0004] Therefore, it is necessary to invent a flange opening assembly and opening device to solve the above problems. Utility Model Content
