[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Next, the present invention is described in detail with reference to schematic diagrams.

[0038] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0039] The present invention provides a semi-automatic welding device for metal door panel processing, which can perform intermittent welding operations between the two sides of the gusset plate and the metal door panel without disassembling the clamp, does not require frequent disassembly and assembly of the clamp, and improves the welding efficiency. Example

[0040] Figure 1-3 The diagram shows the structure of the first embodiment of the semi-automatic welding equipment for metal door panel processing of the present invention. Figure 1-Figure 3 In this embodiment, a semi-automatic welding device for metal door panel processing includes a frame 100, a driving assembly 200, a lifting plate 300, a rotary welding assembly 400, a dust collection assembly 500, a filtering assembly 600 and a conveying assembly 700.

[0041] An operating table 110 is installed at the bottom of the frame 100, and a metal door panel and a gusset plate are located on the top of the operating table 110, and the gusset plate is placed on the top of the metal door panel.

[0042] The driving assembly 200 is installed on a side wall of the frame 100 .

[0043] The lifting plate 300 is located inside the frame 100 and is connected to the driving assembly 200. It is driven up and down by the driving assembly 200. The lifting plate 300 is connected to the driving assembly 200. When the driving assembly 200 is started, the driving assembly 200 drives the lifting plate 300 to move up and down.

[0044] When the lifting plate 300 moves upward, the pressing plate 410 is driven to rotate the second fixed plate 180 degrees. When the driving assembly 200 drives the lifting plate 300 to move downward, the lifting plate 300 drives the pressing plate 410 and the slider 420 to move downward. The pressing plate 410 presses the buckle plate against the metal door panel, and the welding head 420a faces the weld position on one side of the buckle plate for welding. When the driving assembly 200 drives the lifting plate 300 to move upward, the pressing plate 410 separates from the buckle plate and drives the pressing plate 410 and the slider 420 to rotate 180 degrees. At this time, as the lifting plate 300 drives the pressing plate 410 to move downward again to press the buckle plate, the welding head 420a is opposite to the weld on the other side of the buckle plate.

[0045] The dust collection component 500 is connected to the slider 420. When the slider 420 moves, it drives the dust collection component 500 to absorb the smoke at the welding site. When the slider 420 and the welding head 420a move for welding, the slider 420 drives the dust collection component 500 to absorb and discharge the gas generated at the welding site.

[0046] The filter assembly 600 is mounted on the side wall of the pressure plate 410 and connected to the dust collection assembly 500 to filter and discharge the smoke and dust guided by the dust collection assembly 500.

[0047] The conveying assembly 700 is installed on the top of the operating platform 110 and is connected to the lifting plate 300. Each time the lifting plate 300 moves upward, it drives the frame 100 to move along the metal door panel.

[0048] Combine Figure 1-Figure 3In this embodiment, a semi-automatic welding device for processing metal door panels is used. When in use, the metal door panel and the gusset plate are placed on the top of the operating table 110, and the driving component 200 is started to drive the lifting plate 300 and the pressing plate 410 to move downward. The pressing plate 410 presses the gusset plate downward against the metal door panel. At the same time, the welding head 420a is opposite to the weld on one side of the gusset plate, and the slider 420 drives the welding head 420a to move to weld the weld on one side of the gusset plate. When the slider 420 moves, it drives the dust collection component 500 to absorb the gas generated at the welding point and transport it to the filter component 600 for filtration and discharge. When welding is completed, the driving component 200 drives the lifting plate 300 to move upward, and the lifting plate 300 drives the slider 420 and the welding head 420a to rotate the second fixed plate 180°, and at the same time drives the conveying component 700 to push the frame 100 to move along the metal door panel. As the driving component 200 drives the lifting plate 300 to move downward again, the pressing plate 410 presses the gusset plate onto the metal door panel. At this time, the welding head 420a is connected to the weld on the other side of the gusset plate, and intermittent welding operations can be performed on both sides of the gusset plate without removing the fixture, thereby improving the welding efficiency between the gusset plate and the metal door panel.
