Abstract

The invention discloses a method for freely forging a casing elevator for petroleum drilling and production. The method includes firstly, discharging a forged piece; secondly, squarely forging a blank; thirdly, dividing a material; fourthly, feeding a lower mould; fifthly, rolling a groove; sixthly, forging ends of two sides; and seventhly, enabling hot-cutting oxygen to flow towards metals at the ends of the two sides. The method has the advantages that used tools are simple, the technological method is scientific and reasonable, the forged piece of the manufactured casing elevator is formed along the shape of a finished product, machining of an arch back can be omitted, and a complete streamline of the forged piece can be kept; the mechanical performance indexes of the casing elevator are superior to those of a part machined in a block mode; and according to the implemented method, at least 25 kilograms of metal can be saved by a casing elevator with the weight equal to or lower than 250 tons, at least 35 kilograms of metal can be saved by a casing elevator with the weight ranging from 350 tons to 500 tons, more than 30 tons of raw materials can be saved if 1000 casing elevators are manufactured annually, and production quality can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and relates to a free forging method using a casing elevator for an oil drill. Background technique [0002] The casing elevator is a key accessory in the lifting equipment of the drilling rig. All the lifting loads are borne by the casing elevator. The casing elevator must meet the requirements of API 8C, and the requirements for materials and mechanical properties are extremely strict. Casing elevator series include 75 tons, 150 tons, 250 tons, 350 tons, 500 tons, 750 tons, 1000 tons and other series of specifications. The shape of the casing elevator is as follows: figure 1 , The material used for casing elevators used in oil drilling is 20SiMn2MoVA, and the weight is generally 100kg to 2500kg. Casing elevators are generally produced in small batches. The forging process of casing elevators is generally divided into several methods: 1) directly forging into squares,...
