Description

Technical Field:

[0001] The present invention relates to the field of structure manufacturing, and particularly to a manufacturing method for a twisted T-shaped profile panel. Background Art:

[0002] Currently, when panels of the same structure are butt-jointed, if the two butt-jointed panels are not in the same plane, it will cause the butt joint seam to be uneven and the butt edges to be misaligned in a scissor-like pattern. During the traditional shipbuilding process, for panels with such a butt-joint form, no treatment is carried out in the previous process, and the scissor-like pattern is flattened and adjusted smoothly during on-site installation so that the two edges can be butted smoothly.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0031] These and other features of the present application will become apparent from the following description of the preferred forms of the embodiments given as non-limiting examples with reference to the accompanying drawings.

[0032] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art can surely implement many other equivalent forms of the present application, which have the features as described in the claims and thus are all within the protection scope defined thereby.

[0033] When combined with the accompanying drawings, the above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description.

[0034] Hereinafter, specific embodiments of the present application will be described with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present application and can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to clarify the true intention based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis and representative basis for the claims to teach those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0035] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.

[0036] In some special ship types, there are the following problems:

[0037] 1. The scissor angle is too large, and the maximum angle even reaches 30°.

[0038] 2. The panel thickness is relatively thick, with the thickness > 25 mm.

[0039] When using traditional processing methods, it is difficult to take reliable and effective methods on-site to adjust a particularly thick flat iron panel by a large angle to achieve smooth alignment. There are problems such as being unable to press, not being able to press smoothly, and damaging the base material during heating.

[0041] In one embodiment, as Figures 1 to 6 shown, the present invention provides a method for manufacturing a twisted T-shaped profile panel, and the method for manufacturing the twisted T-shaped profile panel includes:

[0042] Construct a first connecting plate with a first width and a second connecting plate with a second width in space, wherein the edges to be connected of the first connecting plate and the second connecting plate are arranged opposite to each other;

[0043] Arrange multiple spline curves on the first edge with the first width and the second edge with the second width;

[0044] Generate a cross-sectional line with multiple spline curves arranged thereon;

[0045] Manufacture a sample box according to the cross-sectional line to manufacture the twisted T-shaped profile panel.

[0046] In this embodiment, a specific implementation manner of the method for manufacturing a twisted T-shaped profile panel is provided. In the AM manufacturing software, the first width and the second width of the first connecting plate and the second connecting plate are equivalent to two lines in space. After connecting the corresponding ends, as Figure 1 shown, and multiple parallel spline curves are arranged at intervals on the first width and the second width. In addition, in the length direction, multiple cross-sectional lines are arranged at a certain interval, and the formation of multiple cross-sectional lines helps to solve the technical problem in the prior art of lacking a method for manufacturing a connecting plate at a spatial position on a ship.

[0047] In one embodiment, the manufacturing of the sample box according to the cross-sectional line to manufacture the twisted T-shaped profile panel includes:

[0048] Manufacture partitions with different upper edge lines for each cross-sectional line, wherein the heights of the partitions correspond to different cross-sectional lines;

[0049] Arrange the partitions at real distance intervals;

[0050] Manufacture the twisted T-shaped profile panel according to the positions of the partitions.

[0051] In this embodiment, a specific implementation manner of manufacturing the sample box according to the cross-sectional line to manufacture the twisted T-shaped profile panel is provided.

[0052] In one embodiment, there are three partitions, including a front partition, a middle partition, and a rear partition.

[0053] In this embodiment, a specific implementation manner of establishing the three front partitions, the middle partition, and the rear partition for surface fitting is provided.

[0054] In one embodiment, before the step of generating cross-sectional lines of multiple spline curves, the method further includes:

[0055] Modeling according to the plate thickness of the twisted T-shaped profile panel.

[0056] In one embodiment, the partition material is made of a wooden board.

[0058] Installing the manufactured multiple partitions on the bottom plate to form a three-dimensional sample box.

[0059] In one embodiment, after the step of installing the manufactured multiple partitions on the bottom plate to form a three-dimensional sample box, the method further includes:

[0060] Processing the panel using a cold pressing or line heating and plate bending processing technique to manufacture the twisted T-shaped profile panel.

[0061] In one embodiment, the three-dimensional sample box is the same as the actual size.

[0062] Beneficial effects:

[0063] This method reduces the installation man-hours of the twisted panel, effectively avoids the difficult on-site adjustment in the traditional manufacturing method, and at the same time improves the aesthetics after the panel is installed.

[0064] Through the sample box, the panel is pre-processed according to the contour of the sample box. The processing process is easy, the precision control is convenient, and the panel line is smooth.

[0065] Moving the process forward avoids the subsequent on-site adjustment, saves time and effort, and avoids damage to the base material.

[0066] Overall, the efficiency is improved, the quality is enhanced, and the cost is reduced.

[0067] The man-hours for processing the panel with the sample box to make its line pre-twisted is 1 / 5 of the man-hours for on-site hot work adjustment to make it smooth.

[0068] The line of the finished product processed by the sample box is of higher quality than the line adjusted by on-site hot work. According to conventional statistics, in about 20% of the cases, the on-site operation quality is poor and the plate needs to be replaced. Therefore, this method avoids the replacement caused by plate replacement and base material damage, saving 20% of materials and man-hours.

[0069] After applying this method, the construction location results are significantly more aesthetically pleasing, and the construction difficulty is significantly reduced. Therefore, the shipowner and the ship surveyor praised this construction method, and the on-site construction team was very satisfied with this method. Overall, the on-site construction efficiency was improved, the construction quality was enhanced, and the construction competitiveness of Guangzhou Shipyard International was elevated.
