Petroleum casing collar automatic production line

Abstract

The invention discloses a petroleum casing collar automatic production line. The petroleum casing collar automatic production line comprises a long casing conveying device, a long casing cutting device, a marking device, a collar blank conveying device, a lifting device, a mechanical hand structure, a machining device and other multiple process devices; and the long casting cutting device, the marking device, the collar blank conveying device and the lifting device are connected through connection conveying plates. According to the petroleum casing collar automatic production line provided bythe invention, the mechanical devices cooperates with electrical control, the process that taking and conveying of a long casting, turning of the end surface and the outer circle of the long casting,cutting off of the long casing, marking of a collar blank, conveying of the collar blank between planes different in height, mechanical hand grabbing and machine tool machining are automatically and efficiently conducted is achieved, manpower is saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical engineering and relates to an automatic production line for oil casing couplings. Background technique [0002] With the continuous development of my country's petroleum industry, the demand for petroleum oil casing and related parts is increasing. The oil casing is mainly used to support the well wall during the drilling process and after the completion of the well, so as to ensure the normal operation of the entire oil and gas well after the drilling process and the completion of the well; the oil pipe mainly transports the oil and gas at the bottom of the well to the ground. The oil casing coupling is a necessary element used to connect two pipe strings in the oil casing. The oil casing coupling is a necessary workpiece used to connect two oil casings. The main production process of petroleum oil casing couplings is as follows. First, a long pipe needs to be transported to a cutting device (saw or ...

Problems solved by technology

In actual production, in one of the processing links, it may happen that a certain coupling has not completed the scheduled operation, and the next coupling has been transported, causing interference and affecting normal work

[0007] In the current oil and casing coupling processing process, in the process of transporting the preliminary processed coupling blank to the machine tool for boring and thread processing, workers generally need to manually transport the coupling blank to the processing position on the machine tool. The processed couplings are manually removed and transported to the collection by workers, which consumes a lot of manpower; there are also a small number of complex large-scale production lines that can be automatically transported and processed, but the equipment cost is relatively high
