Problems solved by technology

[0002] The fender tube of a ship is a protective structure against external impact when the ship is berthing and impacted. It is usually a steel "U"-shaped groove with a length of 6m, a groove width of 180mm, a bottom arc of 60mm, and a thickness of 6mm. It is required that the groove width after forming shall not be greater than 185mm or less than 180mm, and the bottom arc shall be smooth and regular without indentation. The current conventional manufacturing method of fender tube is manufactured by ordinary oil pressure process, the production efficiency is low, and the overall quality cannot reach that of the ship.

Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with specific embodiments.

[0012] A method of pressing a fender tube by a numerical control bending machine in the present invention comprises the following steps:

[0013] 1) Divide the processing line to be pressed equally on the sheet material that needs to be processed into the fender tube, and the distance between the processing lines is 15-20mm; that is, draw the equally divided pressing processing line on the sheet material;

[0014] 2) Put the sheet on the CNC bending machine and press it according to the processing line. The CNC bending machine uses the largest bottom mold;

[0015] 3) Press from one side of the sheet first, and the pressing angle of the first four processing lines on this side is 175 o 、170 o , 160 o 、145 o , at an angle of 5 o Adjust within, then press 145 o The angle is suppressed to two-fifths of the processing area. If the angle does not match the actual model, ...

Abstract

The invention relates to a method for pressing a fender pipe through a numerical control bending machine. The method is characterized by comprising the following steps that firstly, pressing machining lines are equally arranged on a board required to be machined into the fender pipe, and the distance between the machining lines ranges from 15 mm to 20 mm; and secondly, the board is fed to the numerical control bending machine and is pressed according to the machining lines, and a largest bottom die is used on the numerical control bending machine. The method is high in production efficiency, and the quality meets the requirement.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for pressing a fender pipe by using a numerical control bending machine. Background technique [0002] The fender tube of a ship is a protective structure against external impact when the ship is berthing and impacted. It is usually a steel "U"-shaped groove with a length of 6m, a groove width of 180mm, a bottom arc of 60mm, and a thickness of 6mm. It is required that the groove width after forming shall not be greater than 185mm or less than 180mm, and the bottom arc shall be smooth and regular without indentation. The current conventional manufacturing method of fender tube is manufactured by ordinary oil pressure process, the production efficiency is low, and the overall quality cannot reach that of the ship. Quality requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for pressing ...
