Description
Technical field
The invention belongs to shackle technical fields, more particularly to a kind of solid forging method of large-scale shackle.
Background technique
Shackle is one kind of rigging, can be divided into peculiar to vessel and land with two kinds by field of employment, presently preferred shackle is generally all
The history for the ordinary carbon steel of changing over alloy steel, national standard shackle include it is general rise reuse shackle, shackle peculiar to vessel and
Common shack, heavier-weight, volume is larger, is generally not mounted to the position infrequently dismantled.
Existing shackle leads to heavier-weight since the gravity of receiving is higher, and volume is bigger than normal, however not to shape requirement
Height, small-sized shackle generally use swaging technique, and for large-scale shackle, forging difficulty is larger at present, difficult forming, to reduce
The production efficiency of large-scale shackle is unable to satisfy the using effect of user.
Summary of the invention
The purpose of the present invention is to provide a kind of solid forging methods of large-scale shackle, by not influencing to hold in finished form
Under conditions of carrying power, shackle body is set as the shape being made of one group of flat part, one group of ring part and arc interconnecting piece spy
Sign, using forging pole, both ends are flattened, both ends mill out plane, remaining position vehicle circle when production, the process of last bending is solved
Existing large size shackle is not easy to the problem that molding causes production efficiency lower.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of solid forging method of large-scale shackle, comprising the following steps:
SS01 blanking: according to require to raw material chemically examine, analysis and blanking；

Enclose, can not burning, forging equipment is 2 tons of Single arm, by forging process for fuel at pole shape, and both ends is flattened；
SS03 Vehicle Processing: milling out plane for round steel both ends, remaining position vehicle circle, and carries out tentatively lossless using ultrasonic wave
Detection；
SS04 bending and molding: bending part reason is carried out after workpiece is placed in a heating furnace heating after non-destructive testing is qualified, is made
Workpiece meets regulation technique shape；
SS05 surface treatment: polishing finishing is carried out to finished product, stress sensitive area is removed, is trimmed to predetermined size and polishes；
SS06 finished product detection: each finished product is all made of ultrasonic wave and carries out non-destructive testing, and detect finished surface it is whether bright and clean,
The low intensive local defects of drop such as impulse- free robustness, flawless and folding burning, and finished product both ends carry out Magnetic testing, and select sample
Carry out deformation test and fatigue test；
SS07 storage: spraying oil liquid antirust on finished product, and wraps up sealing after sponges cover and be placed on frame body and be put into warehouse.
Further, ultrasonic cutting machine blanking is used in the SS01, guarantees the uniform quality of blank, and guarantee blanking
Part surface is smooth, no saw kerf and corner angle.
Further, with Single arm, by the round steel blank of heating, jumping-up is pulled out repeatedly in the SS02, makes even tissue, and
So that product forging ratio > 3.
Further, the finished product in the SS06 includes one group of flat part, one group of ring part and an arc interconnecting piece, described
The cross section of arc interconnecting piece is half circle structure, and two flat parts are in flat distribution of shapes, the two ring part positions
It is upper opposite.
Further, 5 samples are extracted in the deformation test in the SS06, and each sample must be able to bear DNV ship
The verifying power of defined in inspection specification.
Further, 5 samples are extracted in the fatigue test in the SS06, the maximum value of each ringing power is
0.75 times that power is verified in DNV ship inspection specification, minimum verifies power in the range of 0-3KN, and acting frequency unloads between 6-26HZ
Button remains to carry after must bearing 10000 circulations in such a situa-tion.
The invention has the following advantages: the present invention is by will unload under conditions of finished form does not influence bearing capacity
Button ontology is set as the shape feature being made of one group of flat part, one group of ring part and an arc interconnecting piece, using forging circle when production
Stick, both ends flatten, both ends mill out plane, remaining position vehicle circle, and the process of last bending is convenient for convenient for the molding of shackle body
Production, improve production efficiency, and reduce production cost, while to finished product both ends carry out Magnetic testing, finally to sample into
Row deformation test and fatigue test improve test effect, while spraying oil liquid antirust in storage, ensure that shackle body
Product quality.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
