the production process for the anchor windlass gypsy

 

 

Design phase: During the design phase of the anchor windlass gypsy, its dimensions, structure, materials, and other technical parameters need to be determined. The designer needs to determine the specifications and requirements of the anchor windlass gypsy based on factors such as the ship type, anchor size, and ship usage environment.

 

Forging: The anchor windlass gypsy is usually made through forging, which is a process of heating metal and shaping it using large presses. Through hammering and pressing, the metal billet gradually forms the rough shape of the anchor windlass gypsy.

 

Precision machining: After the forging process, precision machining is required to achieve the required accuracy and surface finish. This typically involves processes such as turning, milling, drilling, and grinding.

 

Heat treatment: The anchor windlass gypsy needs to undergo heat treatment to change its structure and mechanical properties. Common heat treatment methods include annealing, normalizing, quenching, and tempering.

 

Surface treatment: Surface treatment can improve the corrosion resistance and wear resistance of the anchor windlass gypsy. Methods such as electroplating, spraying, or chemical treatment are commonly used.

 

Quality inspection: Multiple quality control checks are required during the production process, including raw material quality inspection, process control, and finished product inspection, to ensure that the anchor windlass gypsy meets specifications and standards.

 

Packaging and transportation: After production is complete, the anchor windlass gypsy needs to be packaged and labeled according to customer requirements and transported for delivery.

 

 

Material

Our wildcat is manufactured from medium-strength carbon steel castings, which provide a surface hardness of approximately 150HB.

This level of hardness ensures that the wildcat is strong enough to withstand the high stresses and loads involved in anchoring, while also providing good resistance to wear and abrasion. Choosing a high-quality wildcat made from the right materials is crucial for ensuring the reliability and safety of the anchoring system.

A chain groove is a circumferential groove located at the centerline of the chain on the wildcat, designed to provide clearance for links passing perpendicular to the shaft centerline.

Chain pockets are recesses between the flanges and whelps on the wildcat, where links with flat sides parallel to the shaft centerline are placed.

A detachable link is a “C” shaped link used to join anchor chain lengths and appendages into a continuous length aboard the ship. It is closed by a pair of closing pieces and a taper pin.

Flanges are circumferential rims located on the outside of the whelps, chain pockets, and chain groove.

Link grip refers to the inside dimension of a chain link, which represents the effective length of a chain link in an assembled chain. It is generally four times the nominal size of a stud link anchor chain.

Whelps are protrusions on the inside of the flanges of the wildcat that resemble gear teeth. They are shaped and sized to follow the path of the chain as it enters and leaves the wildcat. The faces of the protrusions are separated by the chain groove, which allows links with the flat side perpendicular to the shaft centerline to pass, while blocking links with the flat side parallel to the shaft centerline.

A wildcat is a rotating component designed to receive assembled chain links and connecting links around its circumference. It is specially contoured and of suitable strength to impart motion to the chain when rotated.

Chain warping Test Methods

Measure the size of the anchor gyspy with the corresponding measuring tool

Check and check the grade and material certificate of the material used for the cable lifter

testing regulations

The inspection of the anchor gypsy is divided into type inspection and factory inspection.

Type inspection

a) First products of various modes:

b) Production and type identification of old products:

c) After formal production, due to major changes in structure, materials and processes, it is enough to affect performance:

d) Resume production after 4 years of production stoppage:

e) The factory inspection result is quite different from the previous type inspection result:

f) National quality supervision agencies have requirements.
