Embodiment Construction
[0024] Below in conjunction with embodiment the preparation method of the present invention is further described:
[0025] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; either directly or indirectly through an intermediary. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.
[0026] See Figure 1 to Figure 3 , is a schematic block diagram of the technical process of the embodiment of the vibration aging method in the production process of the longitudinal welded pipe of the present invention. In the production of the existing longitudinal welded pipe, the raw material preparation is usually uncoiling and shearing, and the purpose...

The invention relates to the technical field of welded pipe production, in particular to a vibration aging method and an aging movable frame in a production process of a straight seam welded pipe, theoperation steps are as follows: 1) Before being stored in a warehouse, the straight seam welded pipe is suspended below the aging movable frame by an suspension member, and a vibration exciter is placed at a fixing position of the straight seam welded pipe; 2) The aging movable frame moves in the direction of the welded pipe warehouse under the driven of power, and continuously vibrates during the moving process, and the lasting time of the excitation is 20-30 minutes; 3) When the straight seam welded pipe reaches the welded pipe warehouse, the excitation stops; and 4) The straight seam welded pipe is placed on a welded pipe rack of the welded pipe warehouse in turn, and the vibration exciter and the suspension member are removed; and then the operation is ended. Compared with the priorart, the beneficial effects of the invention are: 1) the aging treatment during the transfer process of the welded pipe to the welded pipe warehouse can be completed automatically, and the vibration aging requirements and production scheduling of the straight seam welded pipe can be met; 2) the production efficiency and quality of straight seam welded pipe are improved, and the energy consumptionand the number of operators are saved.
Description
technical field [0001] The invention relates to the technical field of welded pipe production, in particular to a vibration aging method and an aging moving frame in the production process of straight seam welded pipes. Background technique [0002] Longitudinal welded pipes, steel pipes made of hot-rolled or cold-rolled steel plates or steel strip coils welded on welding equipment are called straight seam welded pipes. Welded pipes mainly have the following applications: 1) General welded pipes are used for the transportation of general lower pressure fluids such as water, gas, air, oil and heating steam. 2) Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings, installation of machinery and equipment. 3) Straight seam electric welded pipe (YB242-63) is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. It is usually divided into ...
