Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a production process for a T-shaped material with chamfered edges assembled in one piece. Background Art

[0002] The T-profile production line is a production line used for manufacturing T-profiles for ships. T-profiles in the field of shipbuilding are generally made of two steel plates, namely the face plate and the web, which are assembled and welded in a "T" shape perpendicular to each other.

[0003] The processes of conventional T-profile production lines mainly include chamfering, assembly, welding and correction. Figure 1 The layout of the traditional T-profile production line includes five areas: chamfering, assembly, buffering, welding, and correction. It is equipped with chamfering machines, assembly machines, welding machines, correction machines, and mechanized conveying such as rollers. That is, the T-profile production line is composed of special machines and conveyors to complete the T-profile production. It is required that the length of each work area must be longer than the length of the panel, and a margin of 1 to 2 meters is left. According to the order of processes, among them:

[0004] In the chamfering area 10-1, a plurality of panel centering devices are arranged at intervals along the conveying direction through the first conveying roller in the area to position and center the panel on the line, and then the chamfering machine 6 arranged at the output end of the conveying roller in the area rolls the free edge of the panel on the line into an R shape at a constant speed to chamfer the four corners. Of course, the corresponding speeds are different for panels of different thicknesses;

[0005] In the assembly area 10-2, the web turning and centering device 4 and the other panel centering device 5 are arranged alternately along the conveying direction of the first conveying roller in the area; the web 9 is electromagnetically attracted by the adsorption turning device on the web turning and centering device 4 and then rotated 90 degrees around the X axis to stand up, so that the bottom long side of the web is located correspondingly on the center line of the panel 8 conveyed from the chamfering area, and the web 9 is centered by the web turning and centering device 4, and then the adsorption turning device is powered off, and then the assembly machine 7 at the output end of the first conveying roller in the area performs assembly spot welding on the panel and the web; the conveying speed of the first conveying roller in this area is also constant;

[0006] In the buffer area 20, the assembled T-profiles are transported by the second conveyor roller 20-1 therein, and the temporarily unused assembled T-profiles can be laterally transported and stored in cooperation with the chain conveyor device 20-2 in the area, and multiple profiles can be stored;

[0007] One or more welding stations can be set in the welding area. It includes a general welding platform 30-1 and one or more multi-electrode gantry T-type automatic welding machines 30-2. The multi-electrode gantry T-type automatic welding machine is used to complete the T-profile welding operation on the welding platform;

[0008] The correction area includes a correction machine and two workstations located before and after the correction machine, namely the front correction workstation and the rear correction workstation. The front and rear workstations are respectively equipped with a third conveying roller 40-3 and a lifting roller 40-2 to cooperate with the correction machine 40-1 to correct the deformation of the T-shaped material after welding.

[0009] That is, the process flow adopted by the traditional T-profile manufacturing production line is mainly as follows:

[0010] (1) The panel is aligned on the line and transported to the chamfering machine;

[0011] (2) The four corners of the panel are chamfered by a chamfering machine to complete the chamfering function;

[0012] (3) The web is turned 90° and assembled through the support and panel;

[0013] (4) T-profile assembly and spot welding to complete the assembly function;

[0014] (5) T-profiles use double-head automatic welding to complete the welding function;

[0015] (6) Before the T-profile is transported to the straightening machine, the welding deformation is corrected to complete the correction function;

[0016] (7) Go offline.

[0017] Compared with other raw materials and products in the shipyard, the T-profiles used in ships have smaller width and height, but significantly larger length. Generally speaking, the maximum width and height are less than 1 meter, while the length can reach 20 meters. Therefore, the T-profile manufacturing production line with traditional layout usually occupies a larger area of ​​the shipyard, affecting the layout of more other production equipment and facilities in the shipyard. In general, the sum of the lengths of the chamfering area and the assembly area in the existing production line is 45 meters. Summary of the invention

The displacement driving cylinder 7-53 is used to drive the transverse displacement rod 7-52 to extend inward to push the web 9 and the panel 8 tightly. Since the positioning roller 7-54 and the pushing roller 7-51 are both rotatable around the Z-axis, they can position the panel and the web without affecting the transportation of the panel and the web.
