Specific embodiments

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0023] Referring to Figures 1-3 , a simple transducer for breaking the edges of multiple welding plates, including a rotary transducer 1 and a control box 2 installed on a base 3. A rotary table 5 is installed at the top of the rotary transducer 1, and a zero reset component is installed on the rotary table 5. A workbench 11 is installed at the top of the rotary table 5 through multiple connecting columns 7. A material inlet 9 is provided in the middle of the workbench 11, a material box 10 is placed in the material inlet 9, and a plurality of radially adjustable arc-shaped limiting plates 8 are installed on the circumferential inner wall of the material inlet 9. An inclined cutting torch 15 with adjustable position is installed above the workbench 1. The tip of the cutting torch 15 corresponds to the material inlet 9, and the cutting torch 15 is connected with a mixed oxygen pipe, a high-pressure oxygen pipe and a natural gas pipe.

[0024] Furthermore, the zero reset component includes a zero reset sensor 4 installed at the bottom of the rotary table 5 and a foot switch installed at the bottom of the rotary transducer 1. The foot switch is electrically connected to the zero reset sensor 4 and the control box 2. When the workbench 11 is in any position, step on the foot switch once, and the zero reset sensor 4 monitors that the workbench 11 rotates to the zero point to achieve reset.

[0025] Further, an angle counter and an incremental rotary angle device are installed on the rotary transducer 1, which can set the rotation angle. The rotation angle can be set arbitrarily from 0° to 360°. When rotating, the angle increases degree by degree. When the set angle is reached, the rotation of the rotary transducer 1 stops. For example, if 53° is set and the foot switch is stepped on, the workbench 11 rotates to 53°, the rotary transducer 1 stops, the incremental rotary angle device displays 0°, and at the same time an electrical signal is sent out. The electrical control starts timing upon receiving the signal. At the same time, the cutting gas is shut off, and only the preheating oxygen and natural gas remain to preheat the workpiece. When the preheating time is up, the workbench 11 rotates again, and at the same time the valve of the high-pressure oxygen pipe is opened to cut the second workpiece. The incremental rotary angle device starts to record the rotation angle from 0° again, rotates to 53° and then stops. At the same time, the incremental rotary angle device displays 0°. In this way, the upper plate of the workbench 11 is cut, and the foot switch is stepped on to rotate to zero. Press the RST key on the incremental rotary angle device, and the angle of the incremental rotary angle device is 0° again.

[0026] Further, valves are installed in the mixed oxygen pipe, high-pressure oxygen pipe and natural gas pipe, and the valves are electrically connected to the control box 2.

[0027] Further, a vertical guide rod 12 is fixedly installed on one side of the base 3. A horizontal guide rod 13 is installed on the vertical guide rod 12. Sliding sleeves 14 are sleeved on both the horizontal guide rod 13 and the vertical guide rod 12. The sliding sleeve 14 on the vertical guide rod 12 is fixedly connected to the end of the horizontal guide rod 13. A locking bolt is threadedly connected to the sliding sleeve 14. The bottom plate of the sliding sleeve 14 on the horizontal guide rod 13 is fixedly installed with a connecting frame 16. The connecting frame 16 and the cutting torch 15 are rotationally connected through a damping rotating shaft, which can adjust the vertical and horizontal positions of the cutting torch 15 and can also adjust the angle.

[0028] Further, a positioning head 6 is fixedly installed at the bottom of the material box 10. A positioning groove adapted to the positioning head 6 is provided at the center of the rotating table 5, which is convenient for positioning. The gas-cut iron slag can fall into the material box 10 through the material opening 9 for centralized collection, improving the working environment quality.

[0029] Further, a plurality of mounting frames 19 are fixedly installed on the circumferential side wall of the workbench 11. A screw rod 20 is rotatably connected to the mounting frame 19. A slide plate 18 is threadedly connected to the screw rod 20. A connecting rod 17 is fixedly connected to the side wall of the slide plate 18. The connecting rod 17 extends radially into the material opening 9 and is fixedly connected to the corresponding arc-shaped limiting plate 8. A turning handle 21 is installed at the end of the screw rod 20. A scale is installed at the bottom of the mounting frame 19. According to different types of welded parts on the shaft, only need to rotate the turning handle 21 to drive the screw rod 20 to rotate, and then drive the connecting rod 17 to move through the slide plate 18, thereby adjusting the radial position of the arc-shaped limiting plate 8. Its function is to abut the arc opening of the welded part against the side wall of the arc-shaped limiting plate 8 when placing the welded part, for initial position positioning, which is convenient for quick placement.

[0030] When the workbench 11 is at any position, step on the foot switch, the workbench returns to the zero point (starting position), press the angle counter reset button, and the angle counter is reset to zero.

[0031] Press the start button on the control box 2, the valves of the mixed oxygen pipe and the natural gas pipe are opened, the operator ignites the preheating, and presses the high oxygen button on the control box 2 after preheating, the valve of the high-pressure oxygen pipe is opened, and the workbench 11 rotates at the same time, and gas cutting begins.

[0032] The workbench 11 rotates the required degree and reaches the starting point of the next gas-cutting plate and stops. At the same time, the valve of the high-pressure oxygen tube is disconnected, and only the valves of the mixed oxygen tube and the natural gas tube are not turned off. After preheating the second plate for 5 seconds (this time is adjustable), the valve of the high-pressure oxygen tube is opened again, and the workbench 11 rotates again at the same time to break the second plate, and rotates the same degree again to reach the next workpiece, and so on. The cycle continues until the last gas-cutting plate is finished and the workbench 11 stops rotating.

[0033] The workbench 11 does not need to clamp the weldment. Since the gas cutting area of the weldment is an arc, the operator can easily put the processed weldment on the workbench 11 at a suitable position by using the principle of arc symmetry. According to the different types of weldments on the shaft, the operator only needs to turn the handle 21 to drive the screw 20 to rotate, and then drive the connecting rod 17 to move through the slide 18, so as to adjust the radial position of the arc limit plate 8. Its function is to make the arc of the weldment touch the side wall of the arc limit plate 8 when placing the weldment, so as to locate the initial position and facilitate rapid placement. Because it is an iron piece, it is very heavy, the gas cutting speed is not fast, and the weldment will not slide when the positioner rotates.

[0034] After a plurality of arc plates are broken through one rotation, the gas cutting slag can fall into the material box 10 through the material opening 9 and be collected centrally, thereby improving the quality of the working environment.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
