[0003] Existing handheld flame cutting equipment, such as Figure 5 shown, moves the cutting by holding the cutting nozzle part, but during cutting, since it is manually moved, the cutting line is prone to bending, affecting the cutting quality. Therefore, a medium and heavy plate flame cutting device and method are proposed to facilitate linear flame cutting. Summary of the Invention

[0004] The purpose of the present invention is to provide a medium and heavy plate flame cutting device and method thereof to solve the problem in the above background technique that existing handheld flame cutting equipment moves the cutting by holding the cutting nozzle part, but during cutting, since it is manually moved, the cutting line is prone to bending, affecting the cutting quality.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A medium-thick plate flame cutting device includes a first chute, a second chute and a handheld flame cutting machine. A first slider is slidably connected in the first chute. The top surface of the first slider is fixedly connected with a mounting seat. A second slider is fixedly connected to the mounting seat corresponding to the second chute. The second slider corresponds to and is adapted to the second chute. The mounting seat slides along the first chute through the first slider and slides along the second chute through the second slider. An adjusting plate is provided outside the mounting seat. A positioning groove is formed in the adjusting plate. The positioning groove is adapted to the cutting flame head of the handheld flame cutting machine. An adjusting mechanism is provided between the adjusting plate and the mounting seat. Clamping plates are fixedly connected to the mutually remote ends of the first chute and the second chute. A medium-thick plate is provided between the clamping plates. Anti-slip pads are fixedly connected to the bottoms of the clamping plates. The clamping plates clamp the two sides of the medium-thick plate through the anti-slip pads.

[0006] As a further scheme of the present invention: A third chute is fixedly connected to the side of the first chute close to the second chute. A slide rail adapted to it is slidably connected in the third chute. The slide rail is fixedly connected to the second chute.

[0007] As a further scheme of the present invention: A hand-tightening bolt is threadedly connected to the bottom surface of the third chute. The hand-tightening bolt is inserted into the third chute and abuts against the outer wall of the slide rail. A threaded hole for threaded connection of the hand-tightening bolt is provided at the bottom surface of the end of the third chute.

[0008] As a further scheme of the present invention: Guide sleeves and guide rods are respectively fixedly connected to the opposite sides of the clamping plates. One end of the guide rod is inserted into the guide sleeve and is slidably connected to the guide sleeve.

[0009] As a further scheme of the present invention: The adjusting mechanism includes end plates, vertical rods and threaded turning handles.

[0010] As a further scheme of the present invention: The end plates are symmetrically fixedly connected to the upper and lower parts of the side of the mounting seat. The vertical rods are symmetrically fixedly connected between the two end plates. The threaded turning handle rotatably penetrates and connects the middle parts of the two end plates. The threaded turning handle threadedly penetrates the adjusting plate. A threaded hole for threaded connection of the threaded turning handle is formed in the adjusting plate. The vertical rod slidably penetrates the adjusting plate. A round hole for the vertical rod to penetrate and slide is formed in the adjusting plate.

[0011] A medium-thick plate flame cutting method has the following method steps: S1: First, slide the first chute and the second chute through the cooperation of the third chute and the slide rail, so that the clamping plates move away from each other; S2: Further, clamp the two sides of the medium-thick plate by the clamping plates through the anti-slip pads, and then rotate the hand-tightening bolt to fix the third chute and the slide rail to each other; S3: Further, place the flame cutting head of the handheld flame cutting machine in the positioning groove; S4: Further rotate the threaded handle to drive the adjusting plate to slide up and down along the vertical rod, thereby controlling the placement height of the flame cutting head of the handheld flame cutting machine. S5: Start the handheld flame cutting machine and move the flame cutting head. The mounting seat moves along the first sliding groove through the first slider until the second slider slides into the second sliding groove, and the mounting seat continues to move along the second sliding groove through the second slider, thereby forming a linear cutting effect.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the first sliding groove and the second sliding groove to cooperate with the first slider and the second slider to guide the movement of the mounting seat, and cooperates with the positioning groove on the adjusting plate to guide the movement of the cutting flame head of the handheld flame cutting machine, facilitating the formation of a linear moving cutting effect.

[0013] 2. The first sliding groove and the second sliding groove of the present invention can perform telescopic movement through the cooperation of the third sliding groove and the slide rail, and cooperate with the sliding of the guide sleeve and the guide rod, so as to stably adjust the distance between the clamping plates. After the distance is adjusted, it is fixed by hand-tightening bolts, so that the clamping plates can clamp medium-thick plates of different widths through the anti-slip pads, adapting to the processing of medium-thick plates of different widths.

[0014] 3. By rotating the threaded handle, the present invention can effectively drive the adjusting plate to slide up and down along the vertical rod, thereby conveniently controlling the distance between the cutting flame head of the handheld flame cutting machine and the medium-thick plate, facilitating cutting processing.
