Description

Technical Field

[0001] This invention relates to the field of anchor chain accessory manufacturing technology, specifically to a corrosion-resistant swivel production method and its forming equipment. Background Technology

[0002] The swivel ring body of the anchor chain accessory is a part in the anchor chain accessory. After the swivel ring body of the anchor chain accessory is forged, it needs to be drilled to make holes in order to be used with the swivel ring bolt of the anchor chain accessory. At present, the drilling of the swivel ring bolt of the anchor chain accessory is done by manual clamping and processing. This processing method is time-consuming and labor-intensive, which is not conducive to the production of enterprises. Moreover, the drilled holes are prone to errors, which affect the subsequent actual use.

[0003] For example, the Chinese patent CN114700808B describes a machining process for anchor chain accessory swivel rings, including the following steps: Step 1: Place the anchor chain accessory swivel ring into a clamping fixture and fix it; Step 2: The template adjuster pushes the cutting tool to contact the anchor chain accessory swivel ring and the quick-release template; Step 3: The rotating component drives the anchor chain accessory swivel ring to rotate and contact the rotating cutting tool for cutting; Step 4: The translation component drives the rotating component and the quick-release template to move, and the quick-release template adjusts the cutting tool position. The adjusted cutting tool then processes the rotated anchor chain accessory swivel ring, achieving automated machining of the anchor chain accessory swivel ring. Through the above method, the machining process of this invention achieves automated machining of anchor chain accessory swivel rings, saving time and effort, benefiting enterprise production, and ensuring that the machined hole size meets the processing requirements, guaranteeing the quality of the anchor chain accessory swivel ring and facilitating subsequent practical use.

[0004] The aforementioned machining requires more raw materials and generates a large amount of debris. In addition, machining affects the overall processing efficiency. Furthermore, the existing anchor chain accessory swivel rings are formed from conventional metal rods, and the corrosion resistance of the formed anchor chain accessory swivel rings needs to be improved.
