Abstract
A forging method for a mooring ring comprises the following steps of (1) feeding, (2) blank manufacturing of a mooring ring body, (3) middle bending of the mooring ring and (4) polishing and finishing. According to the forging method for the mooring ring, internal organization of a bow type mooring ring forge piece is compact and even, large loads and impacting can be borne, and ultra-high strength and super toughness can be achieved. In addition, the forging method for the mooring ring is simple and practical, and the production efficiency is high.
Description
Technical field
The present invention relates to a kind of production field of chain peculiar to vessel, relate in particular to a kind of forging method of mooring ring.
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 high strength, obdurability for the mooring ring berthing on boats and ships; When use, mooring ring two connects respectively harbour and hawser.Because mooring ring 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 mooring ring will be provided, and forges the forging with good mechanical property, meets the mooring ring product of size and dimension requirement.
The present invention is comprising the following steps of realizing like this:
A forging method for mooring ring, is characterized in that: comprise the following steps:
(1) blanking
Ensure lower materials and parts smooth surface, remove saw kerf corner angle;
(2) mooring ring body base
Raw material round steel is put into flame furnace to be heated; By heating round steel electricity consumption liquid hammer by round steel shaping shaping forming, get the rectangular of process, then sub-material is carried out respectively at two ends, claps flat pulling, carries out a bending, bending to 90 °, then sub-material, two ends punching, the hole dimension of mooring ring is less than compact dimensions, ensure machining allowance, stage casing part pulls out to forging demand size by special buckling die;
(3) mooring ring bent intermediate
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, and be trimmed to and require size.
Described 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.Interlayer, cracking, groove do not have when blank forging.What described blank forged opens forging temperature is 900-950 DEG C, and final forging temperature is for being not less than 830 DEG C.
Adopt forging method of the present invention, a kind of bow mooring ring 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.
Brief description of the drawings
Fig. 1 is the front view of mooring ring body in the present invention.
Fig. 2 is the side view of mooring ring body in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
As depicted in figs. 1 and 2, be the structural representation of mooring ring body of the present invention.
A kind of step of forging method of change is as follows:
(1) blanking
Ensure lower materials and parts smooth surface, remove saw kerf corner angle;
(2) mooring ring body base
Raw material round steel is put into flame furnace to be heated; By heating round steel electricity consumption liquid hammer by round steel shaping shaping forming, get the rectangular of process, then sub-material is carried out respectively at two ends, claps flat pulling, carries out a bending, bending to 90 °, then sub-material, two ends punching, the hole dimension of mooring ring is less than compact dimensions, ensure machining allowance, stage casing part pulls out to forging demand size by special buckling die;
(3) mooring ring bent intermediate
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, and be trimmed to and require size.
Described 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.Interlayer, cracking, groove do not have when blank forging.What described blank forged opens forging temperature is 900-950 DEG C, and final forging temperature is for being not less than 830 DEG C.
