Abstract
A forging method for R5 level mooring cable annex Kenter shackle, comprises Kenter shackle semi-finished product forging, crosspiece forging; By formulate specification to raw material blanking; Forging temperature controls at 900-1100 DEG C; Use 750KG pneumatic hammer, by flat for the bat of forging jumping-up, pulling, upsetting concentric reducer, bend, and ensure design drawing requirement size; Forging is placed in shaping mould with belt drop hammer steps such as carrying out semi-finished product processing poly-, reaches and meet the object of classification society to the related request of Kenter shackle surface and interior tissue.Effectively ensure that the performance of product.
Description
Technical field
The present invention relates to a kind of forging method of R5 level mooring cable annex Kenter shackle.
Background technology
R5 level mooring cable annex Kenter shackle on deep sea drilling platform is the same with R5 mooring cable has the technical characteristic of high strength, obdurability, corrosion-resistant, antifatigue.According to forging requirement, its surface and interior tissue all should meet the related request of the classification societies such as ABS, DNV.Consider its importance to ocean operation safety, therefore must adopt specific forging method, make the Kenter shackle produced have good combination property.
According to the designing requirement of classification society and deep sea drilling platform, R5 level mooring cable annex should have longer service life, in use procedure over a long time, mooring cable Kenter shackle is owing to bearing tensile load for a long time, and long-term seawater corrosion, its latch can be caused to loosen and come off, Kenter shackle was lost efficacy, cause serious consequence, so the ability of the corrosion resistance and resistance to deformation that how to improve Kenter shackle is a technical barrier.
Summary of the invention
Object of the present invention is exactly the forging method that will provide a kind of R5 level mooring cable annex Kenter shackle, and it can meet classification society to Kenter shackle surface and the related request of interior tissue.The object of the present invention is achieved like this, and a kind of forging method of R5 level mooring cable annex Kenter shackle, is characterized in that: comprise Kenter shackle semi-finished product forging, crosspiece forging; Described Kenter shackle semi-finished product forging process step is: blanking, and require diameter, the length dimension of defined according to design drawing, carry out blanking to raw material, blanking length tolerance is ± 1mm; Non-Destructive Testing is carried out with defectoscope; Heat in reflective box type stove, overheated, burning surface quality defect can not be had; Use 750KG pneumatic hammer, clap flat by forging jumping-up, forging does not have when jumping-up interlayer, cracking defect; Use 750KG pneumatic hammer, by forging pulling, upsetting concentric reducer, the other defect of the interlayer that do not have during forging, cracking, groove and reduction properties of product; Use 750KG pneumatic hammer, forging bent, time bending with the center line of forging for reference operation, and ensure design drawing requirement size; To be placed in shaping mould by forging with belt drop hammer and to carry out semi-finished product processing, guarantee that forging has a smooth finish surface adapted with its manufacture method, answer flawless groove and reduce the other defect of properties of product, before shaping, reply shaping mould checks; Semi-finished product forging is placed on slow cooling in lime or cinder, and after cooling, semi-finished product forging manufacture overlap can be carved with chisel and remove, or is removed with autogenous cutting, application wheel machine polishing after overlap removal, and obtains the smooth finish surface of corresponding manufacturing method; Non-Destructive Testing is carried out with defectoscope; Forging temperature controls at 900-1100 DEG C.Described crosspiece forging process step is: blanking, according to the diameter of specifying, length specification size blanking, blanking length tolerance is ± 1mm, guarantees that raw material must not have folding, that interlayer affects properties of product defect, the material of difference different size, rank, the trade mark, discharge is neat; Non-Destructive Testing is carried out with defectoscope; Heat in reflective box type stove, overheated, burning surface quality defect can not be had; Use 750KG pneumatic hammer, forging is broken into type, the other defect of the interlayer that do not have during forging, cracking, groove and reduction properties of product; Non-Destructive Testing is carried out with defectoscope; Forging temperature controls at 900-1100 DEG C.The present invention can forge the Kenter shackle with superperformance.Reach the related request of classification society to R5 level mooring cable attachment surface and interior tissue.Owing to containing more Mo element and a small amount of V in R5 material, the trace elements such as Nb, Ti, these elements can significantly improve the elevated temperature strength of material, therefore forge difficulty and obviously increase, and the present invention is by improving forging temperature, increase the method for forging surplus, effectively ensure that the performance of product.Fig. 1 is blanking operation schematic diagram of the present invention;
