Abstract
A method for forging a bow shackle includes the following steps: (1) conducting feeding; (2) manufacturing a blank of a body of the bow shackle; (3) bending the body of the bow shackle; (4) conducting polishing and finishing. By means of the method, the internal tissue of a bow shackle forge piece is compact and uniform, and the bow shackle forge piece can bear large loads and impact and has ultra-high strength and ultra-high tenacity. In addition, the method is simple, practical and high in production efficiency. By means of the method, the forge piece which has a good mechanical property is forged, and the bow shackle product meeting the requirements for the size and the shape is forged.
Description
Technical field
The present invention relates to a kind of production field of mooring cable, relate in particular to a kind of forging method of bow shackle.
Background technology
Forging is that one utilizes metal forming machinery to exert pressure to metal stock, makes it produce plastic deformation to obtain the processing method with certain mechanical performance, definite shape and size forging, one of two large parts of forging and stamping (forging and punching press).Can eliminate the defects such as cast condition that metal produces in smelting process is loose by forging, optimize heterogeneous microstructure, simultaneously owing to having preserved complete metal streamline, the mechanical performance of forging is generally better than the foundry goods of same material.The strength member that in associated mechanical, load is high, condition of work is severe, except sheet material, section bar or the weldment of the better simply available rolling of shape, adopts forging more.
There is the technical characterictic of superhigh intensity, superpower toughness for the mooring annex bow shackle on mooring platform, so, when use, each one section of chain link or the eye plate of connecting in bow shackle two, because bow shackle shape is more complicated, therefore need to forge by certain technical process.
Summary of the invention
Object of the present invention is exactly the forging method that a kind of bow shackle will be provided, and forges the forging with good mechanical property, meets the bow shackle product of size and dimension requirement.
The present invention is achieved in that its step is as follows:
(1) blanking
Ensure lower materials and parts smooth surface, remove saw kerf corner angle;
(2) bow shackle body base
Raw material round steel is put into flame furnace to be heated; By the round steel electricity consumption liquid hammer of heating, by round steel shaping shaping forming, two ends are by special bow shackle bulb mould spin, and clap flat punching, and stage casing part pulls out to forging demand size by special buckling die;
(3) bow shackle body bending
The blank that base is completed, is positioned on special bending saddle support and carries out bending, ensures that hammer knocks in blank center when bending, after bending, Special core mold is placed in to shackle home record position, and tup raps shaping;
(4) polishing finishing
To the finishing of polishing of the forging after moulding, scale removal.
Round steel is put into flame furnace heating, and the temperature in flame furnace is controlled at 800-1000 DEG C, insulation 2-3 hour.What described blank forged opens forging temperature is 900-950 DEG C, and final forging temperature is 750-800 DEG C.
Interlayer, cracking, groove do not have when blank forging.
Adopt forging method of the present invention, a kind of bow shackle forging dense internal organization, even, can bear larger load and impact, has superhigh intensity, superpower toughness.In addition, forging method of the present invention is simple and practical, and production efficiency is high.The present invention forges the forging with good mechanical property, meets the bow shackle product of size and dimension requirement.

(3) bow shackle body bending
The blank that base is completed, is positioned on special bending saddle support and carries out bending, ensures that hammer knocks in blank center when bending, after bending, Special core mold is placed in to shackle home record position, and tup raps shaping; Interlayer, cracking, groove do not have when blank forging.Round steel is put into flame furnace heating, and the temperature in flame furnace is controlled at 800-1000 DEG C, insulation 2-3 hour.What described blank forged opens forging temperature is 900-950 DEG C, and final forging temperature is 750-800 DEG C.
(4) polishing finishing
To the finishing of polishing of the forging after moulding, scale removal.
