[0026] The present invention will now describe a lantern frame bending and welding device.

[0027] like Figure 1 and Figure 3 As shown, this utility model provides a lantern frame bending and welding device, including a frame workbench 100 and a bending mechanism 200; the frame workbench 100 has a forming area 300 on its surface; the bending mechanism 200 is disposed on the forming area 300; wherein, the bending mechanism 200 includes an upper bending part 210 and a lower bending part 220; the upper bending part 210 is installed on one side of the forming area 300 and is used to perform bending processing on the upper frame 700; the lower bending part 220 is installed on one side of the forming area 300 and is used to perform bending processing on the lower frame 800.

[0028] The present invention provides a lantern frame bending and welding device. Compared with the prior art, the frame workbench 100 is provided with a bending mechanism 200, which includes an upper bending part 210 and a lower bending part 220. When it is necessary to bend the wire, two wires need to be supplied first. Then, the lower bending part 220 is responsible for bending the lower frame 800, and then the upper bending part 210 is responsible for bending the upper frame 700. The whole bending process is fast and convenient, saving manpower.

[0029] like Figure 4 and Figure 5 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the upper bending part 210 includes an upper top plate 211 and an upper bending plate 212. The upper top plate 211 is disposed on the forming area 300, and the upper bending plate 212 is movably disposed on both sides of the forming area 300.

[0030] Specifically, when it is necessary to bend the wire into the upper frame 700, after the wire is placed in the preset position, the upper bending plate 212 is moved. The upper bending plate 212 begins to contact the wire during the movement. During this process, the wire is always pressed against one side of the upper top plate 211, and as the upper bending plate 212 moves, the wire is eventually bent into the upper frame 700.

[0031] like Figure 4 and Figure 5 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the upper bending part 210 further includes a first V-shaped forming component. The first V-shaped forming component includes a first driver 213 and a first V-shaped block 214. The first driver 213 is disposed on the forming area 300 and located on one side of the upper top plate 211. The first V-shaped block 214 is disposed on the output end of the first driver 213, and the upper top plate 211 has a first groove 2111 that cooperates with the first V-shaped block 214.

[0032] It should be noted that the first actuator 213 is preferably a cylinder. During the bending process, the top of the upper frame 700 also needs to be shaped into a V-shape. In this process, the first actuator 213 is activated, and the output end of the first actuator 213 pushes the first V-shaped block 214. The first V-shaped block 214 contacts the top of the upper frame 700. As the first V-shaped block 214 continues to move, a part of the top of the upper frame 700 is pushed into the first groove 2111. At this point, the top of the upper frame 700 is shaped.

[0033] like Figure 4 and Figure 5As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the lower bending part 220 includes a lower top plate 221 and a lower bending plate 222. The lower top plate 221 is disposed on the forming area 300, and the lower bending plate 222 is movably disposed on both sides of the forming area 300.

[0034] Specifically, when it is necessary to bend the wire into the lower frame 800, after the wire is placed in the preset position, the wire is between the upper top plate 211 and the lower top plate 221. At this time, the lower bending plate 222 is moved. During the movement, the lower bending plate 222 begins to contact the wire. During this process, the wire is always pressed against one side of the lower top plate 221. As the lower bending plate 222 moves, the wire is eventually bent into the lower frame 800.

[0035] like Figure 4 and Figure 5 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the lower bending part 220 further includes a second V-shaped forming component. The second V-shaped forming component includes a second driver 223 and a second V-shaped block 224. The second driver 223 is disposed on one side of the lower top plate 221, and the second V-shaped block 224 is disposed on the output end of the second driver 223. The upper top plate 211 is provided with a second groove 2112 that cooperates with the second V-shaped block 224.

[0036] It should be noted that the second actuator 223 is preferably a cylinder. During the bending process, the top of the lower frame 800 also needs to be shaped into a V-shape. In this process, the second actuator 223 is activated, and the output end of the second actuator 223 pushes the second V-block 224. The second V-block 224 contacts the top of the lower frame 800. As the second V-block 224 continues to move, a part of the top of the lower frame 800 is pushed into the second groove 2112. At this point, the top of the upper frame 700 is shaped.

[0037] like Figure 4 and Figure 5 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, a third driver 225 is also provided on the forming area 300. The output end of the third driver 225 is connected to the lower top plate 221, and the second driver 223 is provided in the receiving area 2211 of the lower top plate 221.

[0038] Specifically, the third actuator 225 is preferably a cylinder. In order to facilitate the molding of the lower frame 800, both the lower top plate 221 and the second actuator 223 are movable. The second actuator 223 is installed in the receiving area 2211 of the lower top plate 221. When the output end of the third actuator 225 starts to move, it will push the lower top plate 221 to start moving, which will in turn drive the second actuator 223 to start moving.

[0039] like Figure 5 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, guide rails 310 are provided on both sides of the forming area 300, and upper bending plate 212 and lower bending plate 222 are provided on the guide rails 310. Both the upper bending plate 212 and the lower bending plate 222 are provided with toothed structures 400. The forming area 300 is provided with a fourth driver 320 and a fifth driver 330 on both sides. The output ends of the fourth driver 320 and the fifth driver 330 are provided with gears, which mesh with the toothed structures 400 respectively.

[0040] It should be further explained that the fourth driver 320 and the fifth driver 330 are preferably motors. When the upper bending plate 212 needs to be moved, the fourth driver 320 is started, and the output end of the fourth driver 320 starts to rotate, which will drive the toothed structure 400 that meshes with it to start moving, and finally drive the upper bending plate 212 to move along the guide rail 310. Similarly, the moving principle of the lower bending plate 222 is the same as that of the upper bending plate 212, so it will not be described again.

[0041] like Figure 3 and Figure 4 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the frame workbench 100 is provided with two upper arc grooves 110 and two lower arc grooves 120, and an annular body 600 is pre-placed at the ends of the two upper arc grooves 110 and the two lower arc grooves 120.

[0042] It should be noted that before bending the wire, annular bodies 600 need to be placed at the ends of the two upper arc grooves 110 and the two lower arc grooves 120. In this embodiment, the annular bodies 600 are nuts. Then, two wires are supplied, one of which passes through the two annular bodies 600 on the two upper arc grooves 110, and the other wire passes through the two annular bodies 600 on the two lower arc grooves 120. When the set distance is reached, the supply of the two wires is stopped, and then the bending of the two wires begins.

[0043] like Figure 1 , Figure 7 and Figure 8As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, the upper side of the frame workbench 100 is provided with a first limiting plate 130 and a second limiting plate 140. The first limiting plate 130 and the second limiting plate 140 are driven to rise and fall by the sixth driver 131 and the seventh driver 141, respectively. The first limiting plate 130 and the second limiting plate 140 are provided with a limiting notch 150 and a limiting groove 160. The limiting notch 150 is used to limit the pre-placed annular body 600 when the first limiting plate 130 and the second limiting plate 140 are in contact with the frame workbench 100. The limiting groove 160 is used to limit the wire when the first limiting plate 130 and the second limiting plate 140 are in contact with the frame workbench 100 and the wire is supplied.

[0044] Furthermore, the sixth actuator 131 and the seventh actuator 141 are preferably cylinders. Before supplying two iron wires, the sixth actuator 131 and the seventh actuator 141 are activated to attach the first limiting plate 130 and the second limiting plate 140 to the skeleton worktable 100. At this time, the four annular bodies 600 are exactly located within the limiting notch 150. Then, two iron wires are supplied, and the two iron wires move along the limiting groove 160 to prevent the iron wires from deviating from the direction during supply.

[0045] like Figure 3 and Figure 4 As shown, in a specific embodiment of the lantern frame bending and welding device provided by this utility model, spot welding components 500 are provided on one side of the two upper arc grooves 110 and the two lower arc grooves 120. Each spot welding component 500 is connected to an eighth driving mechanism 510 and is driven to move by the eighth driving mechanism 510.

[0046] Specifically, after the bending step is completed, welding begins. The eighth drive mechanism 510 is preferably a cylinder. At this time, the output ends of the four eighth drive mechanisms 510 begin to move, pushing the spot welding assembly 500 to move. When it moves to a specific distance, the spot welding assembly 500 welds the two ring-shaped bodies 600 on the upper frame 700 to the upper sides of the lower frame 800, and welds the two ring-shaped bodies 600 on the lower frame 800 to the lower sides of the upper frame 700. Finally, the lantern frame is formed.

[0047] The working principle of this utility model: First, four annular bodies 600 need to be pre-placed, positioned at the ends of the two upper arc grooves 110 and the two lower arc grooves 120 respectively. Then, the first limiting plate 130 and the second limiting plate 140 are pressed down, causing the four annular bodies 600 to enter the limiting notches 150. At this point, two wires are supplied, moving along the two limiting grooves 160 respectively. During the supply process, the two wires will pass through two annular bodies 600 respectively. After reaching the preset position, the supply stops, and the first limiting plate 130 and the second limiting plate 140 rise. Then, the lower frame 800 is bent and formed first, followed by the upper frame 700. During the bending and forming process, the ring-shaped body 600, which is fitted onto the two iron wires, moves along the upper arc groove 110 or the lower arc groove 120. After the bending and forming is completed, the ring-shaped body 600 disengages from the upper arc groove 110 and the lower arc groove 120. The specific forming process has been described in detail above and will not be repeated here. At this time, the output ends of the four eighth drive mechanisms 510 begin to move, pushing the spot welding assembly 500 to move. When it moves to a specific distance, the two ring-shaped bodies 600 fitted onto the upper frame 700 are welded to the upper sides of the lower frame 800, and the two ring-shaped bodies 600 fitted onto the lower frame 800 are welded to the lower sides of the upper frame 700. Finally, the lantern frame is formed.
