Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe outer diameter detection, in particular to an outer diameter detection device for seamless steel pipe manufacturing. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe. It is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and structural steel pipe for automobile, tractor and aviation. Seamless steel pipe is widely used in various chemical and heavy industrial machinery environments.

[0003] The use in various fields has certain requirements on the outer diameter size of seamless steel pipes. Therefore, the outer diameter size needs to be strictly controlled during the manufacturing process of seamless steel pipes. In the existing technology, the outer diameter of seamless steel pipes is mostly detected by vernier calipers during the manufacturing process.

[0004] However, seamless steel pipes have a certain length, and there are often differences in the outer diameters at different positions. In order to better reflect the outer diameter size of seamless steel pipes, it is necessary to detect the outer diameters at different positions. Using a vernier caliper for detection requires multiple tests, and the vernier caliper reading is relatively inconvenient, so the overall detection convenience needs to be improved.
