Description

Technical Field

[0001] The utility model relates to the technical field of deep-sea oil production equipment, in particular to a heat treatment device for forgings used in deep-sea oil production equipment. Background Art

[0002] With the deepening of human development and utilization of oil and gas resources, oil and gas exploration and development have shifted from land to ocean. Therefore, oil extraction operations must also be carried out in the vast ocean. When conducting oil and gas drilling construction at sea, the drilling rig weighing hundreds of tons must have enough support and placement space, and there must also be a place for drilling personnel to live. The offshore oil drilling platform has taken on this important task. Due to the changeable marine climate, the damage of offshore waves and submarine undercurrents, the stability and safety of offshore drilling equipment are more important. In order to better develop deep-sea oil resources, deep-sea oil and gas platforms came into being. The most indispensable part of oil extraction equipment for oil extraction is the drill bit part of the extraction equipment. The drill bit is a consumable, which is made of forgings that are heat treated and hammered, and then manufactured through a series of processes.

[0003] In the existing heat treatment device for forgings of deep-sea oil extraction equipment, since the drill bit of the oil extraction equipment is large in size and the surface texture will be softened after heating, during quenching, a clamp is usually required to clamp the forging out of the combustion furnace for quenching. During the process, there is a risk of forgings slipping and scalding the staff; in the existing heat treatment device for forgings of deep-sea oil extraction equipment, the direction of the forging needs to be continuously adjusted during the forging process to ensure uniform forging, which is more troublesome and affects the production efficiency of the drill bit. Therefore, in view of the above problems, a heat treatment device for forgings of deep-sea oil extraction equipment is proposed. Utility Model Content
