Problems solved by technology

[0003] According to the design requirements of classification societies and deep-sea drilling platforms, R5 grade mooring chain accessories should have a long service life. Corrosion will cause its pins to loosen and fall off, making the Kent shackle invalid and causing serious consequences. Therefore, how to improve the corrosion resistance and deformation resistance of the Kent shackle is a technical problem

Embodiment Construction

[0013] A forging method of Kent shackle, an accessory of R5 mooring chain, is characterized in that: it includes Kent shackle semi-finished forgings and crosspiece forgings; the processing steps of the Kent shackle semi-finished forgings are: blanking, according to the requirements of design drawings According to the specified diameter and length, blank the raw materials, and the blanking length tolerance is ±1mm; use a flaw detector for nondestructive testing; heat in a box-type reverberatory furnace, and there must be no overheating or overburning surface quality defects; use a 750KG air hammer , Upsetting the forgings and flattening them. There should be no interlayers and cracking defects in the forgings during upsetting; use a 750KG air hammer to elongate the forgings and make them upsetting. There should be no interlayers, cracks, grooves and reduced product performance during forging. other defects; use a 750KG air hammer to bend the forging, and operate with the center ...

Abstract

The invention provides a forging method for a kenter link which is an accessory of a R5 grade mooring chain comprising a kenter link semi-finished product forging, and a crosspiece forging. Blanking is carried out to raw materials according to established specification and size; forging temperature is controlled between 900-1100 DEG C; heading and flattening, drawing-down, big and small end ramming and bending are carried out to the forging by a 750KG air hammer, and a required dimension of a design drawing is guarantied; and a forging is placed in a forming die is subjected to steps of semi-finished product processing and the like by a belt drop hammer, such that purpose of satisfying classification society requirements of kenter link surface and internal organizations is reached, and product performance is effectively guarantied.

Description

technical field [0001] The invention relates to a forging method of a Kent shackle attached to an R5 mooring chain. Background technique [0002] R5 grade mooring chain accessories Kent shackles used on deep sea drilling platforms have the same technical characteristics as R5 mooring chains with high strength, toughness, corrosion resistance and fatigue resistance. According to forging requirements, its surface and internal structure should meet the relevant requirements of ABS, DNV and other classification societies. Considering its importance to the safety of marine operations, a specific forging method must be adopted to make the Kent shackles produced have good comprehensive performance. [0003] According to the design requirements of classification societies and deep-sea drilling platforms, R5 grade mooring chain accessories should have a long service life. Corrosion will cause the bolt to loosen and fall off, making the Kent shackle invalid and causing serious conse...
