DETAILED DESCRIPTION

[0022] The embodiment of the present application provides a wind turbine tower aluminum alloy door panel forming and welding device, and its main technical solution is that the aluminum alloy pipe 14 can be bent by providing a clamping assembly and a bending assembly, so that the aluminum alloy pipe 14 is bent into the shape of an aluminum alloy door panel, and then the aluminum alloy pipe 14 and the door panel base frame 16 are welded by a laser welding gun, thereby realizing the forming and welding of the aluminum alloy door panel. The utility model can realize the rapid bending and welding of the aluminum alloy pipe 14 through the above structure, and has the advantages of high efficiency and reduced cost compared with the traditional separate operation production process.

[0023] Example: Refer to Figure 1 - Figure 6 As shown, a wind power tower aluminum alloy door panel forming welding device of this embodiment includes a laser welding gun, an outer support frame 1, an inner support frame 2 is arranged at the middle of the bottom end of the outer support frame 1, and a storage rack 8 is arranged at the middle of the bottom end of the inner support frame 2;

[0024] And, a template 3 is provided at the bottom of the right end of the inner support frame 2, a clamping assembly is provided at the middle of the right end of the template 3, the clamping assembly includes a connecting rod 4, a mounting block 5 is provided at the bottom of the right end of the connecting rod 4, the mounting block 5 is vertically connected to the connecting rod 4, a clamping plate 7 is provided at the middle of the left end of the mounting block 5, and the clamping plate 7 and the mounting block 5 are connected by two sets of fixing bolts 6;

[0025] The bending assembly includes a fixing clamp 11, which can be clamped on the aluminum alloy pipe 14 to be bent and clamped and fixed by fixing screws. A pulley 12 is provided on one side of the fixing clamp 11, and the pulley 12 is slidably connected with a wire rope 13. The head end of the wire rope 13 is connected with a winding auger 9, and the end of the wire rope 13 is connected with a fixing ring 10. The wire rope 13 is wound by the winding auger 9. When the wire rope 13 is wound, the fixing clamp 11 is pulled, so that the aluminum alloy pipe 14 is deformed and bent under force.

[0026] The bending assembly also includes two sets of auxiliary frames 15, which are respectively placed on both sides of the inner support frame 2. In the process of bending the aluminum alloy pipe 14, the two ends of the aluminum alloy pipe 14 are firstly clamped on the top of the auxiliary frames 15 respectively. The auxiliary frames 15 can support the aluminum alloy pipe 14, improve the stability of the bending of the aluminum alloy pipe 14, and avoid the lack of force points at both ends of the aluminum alloy pipe 14. During the bending process, it sags due to gravity, thereby affecting the balance of the bending process.

[0027] In some examples, the winding auger 9 is fixedly installed in the middle of the left end of the outer support frame 1, and the fixing ring 10 is fixedly installed on the two end surfaces of the inner support frame 2. The winding auger 9 winds and tightens the wire rope 13, and the fixing ring 10 fixes and supports the end of the wire rope 13.

[0028] In some examples, the outer support frame 1 and the inner support frame 2 are fixedly connected by welding multiple groups of connecting columns to improve the stability of the connection between the outer support frame 1 and the inner support frame 2.

[0029] In some examples, a universal wheel 81 is provided at the bottom of the right end of the rack 8 to facilitate the staff to move and adjust the position of the rack 8.

[0030] The working principle of the utility model is:

[0031] When the aluminum alloy door panel needs to be welded and formed, the door panel base frame 16 is first placed on the upper surface of the rack 8, and then the rack 8 is moved, and the door panel base frame 16 is moved to the bottom of the inner support frame 2 and aligned with the template 3;

[0032] At this time, the aluminum alloy pipe 14 is placed into the clamping assembly, and the center position of the aluminum alloy pipe 14 is adjusted, and then the clamping plate 7 is pushed by twisting the two sets of fixing bolts 6, so that the clamping plate 7 and the template 3 clamp and fix the center surface of the aluminum alloy pipe 14 at both ends;

[0033] Next, the fixing clamps 11 are installed. The two sets of fixing clamps 11 are respectively installed at the middle positions of the two ends of the aluminum alloy pipe 14, and are clamped and fixed by fixing screws. At the same time, the two ends of the aluminum alloy pipe 14 are respectively clamped on the tops of the two sets of auxiliary frames 15;

[0034] After the above process is completed, the winding auger 9 is started to reel the wire rope 13, and the wire rope 13 slides to evenly pull the fixing clamp 11, so that the aluminum alloy pipe 14 is bent into an arc shape according to the shape of the template 3, and with the assistance of the staff, the aluminum alloy pipe 14 is finally bent into the shape of the door panel bottom frame 16;

[0035] Finally, the aluminum alloy pipe 14 is placed on the door panel chassis 16, and the two are welded and fixed by a laser welding gun to form a completed aluminum alloy door panel. Figure 6 shown.
