A processing method of square anchor lip and square anchor lip

Abstract

The invention discloses a processing method of a square anchor lip and the square anchor lip, belonging to the technical field of shipbuilding. The processing method of the square anchor lip includes the following steps: S1, processing the first bevel on the edge of the stainless steel plate, and evenly opening a plurality of plug welding holes on the stainless steel plate; S2, pasting the stainless steel plate on the lower end of the square anchor lip ; S3, from the center of the stainless steel plate to the outward symmetrical welding of the plug holes in order to form a plug welding seam; S4, welding the joint between the first groove and the square anchor lip to form a groove weld. The square anchor lip is made by the above-mentioned processing method of the square anchor lip. The processing method of the square anchor lip of the present invention has simple processing technology, reliable connection and low manufacturing cost. The square anchor lip of the invention has simple structure, good strength, hardness and corrosion resistance, prolongs the service life of the square anchor lip and improves the aesthetics.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a processing method of a square anchor lip and a square anchor lip. Background technique [0002] The upper and lower openings of the anchor chain drum are generally provided with anchor lips to reduce the wear of the anchor chain and the upper and lower openings. In the existing design, on special ships such as ro-ro passenger ships and semi-submersible ships, square concave anchor lips made of C-Mn steel castings are basically used to reduce the water and air resistance caused by the anchor, and the anchor claw. Water splash caused by hitting water. However, when the anchor is retracting the anchor chain, the anchor will violently rub or collide with the square concave anchor lip, causing damage to the paint on the surface of the anchor lip casting steel, and even causing scratches and indentations on the surface of the anchor lip casting steel. Because the ship works in...

Problems solved by technology

However, when the anchor retracts the anchor chain, the anchor will rub or collide violently with the square concave anchor lip, causing damage to the paint on the surface of the anchor lip casting, and even scratches and indentations on the surface of the anchor lip casting

Since the ship works in a complex marine environment all the year round, the surface of the anchor lip casting with damaged paint or surface damage is easily affected by the environment and severely corroded, which shortens the service life of the anchor lip and affects the aesthetics of the ship's bow, and increases Anchor lip repair and maintenance times
