Abstract
A forging method for a C-shaped shackle comprises the following steps: 1), blanking; 2), heading and flattening; 3), cutting; 4), primary forming; 5), flashing removing; 6) secondary forming; 7), edge removing and polishing. According to the invention, the product of the C-shaped pyriform shackle having a favorable mechanical property and meeting the requirements of dimension and shape is forged. The forging method provided by the invention is suitable for the production of marine mooring chains.
Description
Technical field
The present invention relates to a kind of production technology of marine mooring chain, relate in particular to the forging method of a kind of C type shackle.
Background technology
The technical characterictic that has high strength, obdurability for the mooring cable annex C type shackle on the deep sea drilling platform.During use, mooring cable is enclosed within the shackle two ends, then the shackle cover plate is closed up, the latch of packing into.Because what C type shackle shape was different from standard detachably unloads buckle product, therefore needs a kind of new forging method of design.
Summary of the invention
Purpose of the present invention is exactly the forging method that the shackle of a kind of C type will be provided, and forges the forging with good mechanical property, and the C type that satisfies the size and dimension requirement unloads buckle product.
The present invention is achieved in that the forging method of a kind of C type shackle, it is characterized in that: may further comprise the steps:
1) blanking
Guarantee lower materials and parts smooth surface, remove the saw kerf corner angle;
2) pier is slightly clapped flat
The raw material round steel is put into flame furnace to be heated; The round steel of heating is thick with the round steel pier with pneumatic hammer, and the blank after again pier is thick is clapped flat to corresponding size, and interlayer, cracking defect do not have when pier is thick;
3) cutting
Cut into required shape and size with clapping flat blank, need the control cutting quantity, guarantee to forge surplus; 4) one-shot forming
Blank heating to 900 ~ 1200 ℃ after the cutting is used the shaping mould forging forming, and the final forging temperature of blocking is not less than 830 ℃;
5) deflashing
Blank overlap after the moulding is removed with autogenous cutting, and the chip burr can knock out with hand hammer;
6) post forming
Shaping mould is checked the shaping mould die cavity should have bright and clean surface before the moulding, answer other defective of flawless groove and reduction properties of product; Then the shaping blank with deflashing is heated to 900 ~ 1200 ℃; The preformed blank of heating is put into further forging forming of shaping mould, and final forging temperature is not less than 830 ℃;
7) trimming polishing
Blank after the moulding is made overlap remove with autogenous cutting, with the abrasive machine polishing, obtain smooth finish surface after overlap is removed.
The present invention forges the forging with good mechanical property, and the C type that satisfies the size and dimension requirement unloads buckle product.
The specific embodiment
The forging method of a kind of C type shackle is characterized in that: may further comprise the steps: 1) blanking: guarantee lower materials and parts smooth surface, remove the saw kerf corner angle; 2) pier is slightly clapped flat: the raw material round steel is put into flame furnace heat; The round steel of heating is thick with the round steel pier with pneumatic hammer, and the blank after again pier is thick is clapped flat to corresponding size, and interlayer, cracking defect do not have when pier is thick; 3) cutting: will clap flat blank and cut into required shape and size, and need the control cutting quantity, and guarantee to forge surplus; 4) one-shot forming: the blank heating to 900 after will cutting ~ 1200 ℃ use shaping mould forging forming, the final forging temperature of blocking to be not less than 830 ℃; 5) deflashing: the blank overlap after the moulding is removed with autogenous cutting, and the chip burr can knock out with hand hammer; 6) post forming: shaping mould is checked the shaping mould die cavity should have bright and clean surface before the moulding, answer other defective of flawless groove and reduction properties of product; Then the shaping blank with deflashing is heated to 900 ~ 1200 ℃; The preformed blank of heating is put into further forging forming of shaping mould, and final forging temperature is not less than 830 ℃; 7) trimming polishing: the blank after the moulding is made overlap remove with autogenous cutting, with the abrasive machine polishing, obtain smooth finish surface after overlap is removed.By such method, forge smoothly the C type that meets the shape and size requirement and unloaded buckle product, mechanical performance reaches standard after the heat treatment, has the technical characterictic of high strength, obdurability.
