Description

Technical Field

[0001] This application relates to the field of steel plate processing technology, and more specifically, to a flame cutting device for steel plate processing. Background Technology

[0002] In the field of steel plate processing, flame cutting equipment has become a widely used processing device due to its advantages such as high cutting efficiency and strong applicability. Flame cutting utilizes the high-temperature flame generated by the combustion of a mixture of fuel gas and oxygen to locally melt or vaporize the area of ​​the steel plate to be cut, and then uses a high-speed oxygen stream to blow away the molten metal, thereby achieving separation of the steel plate.

[0003] However, in the actual application of existing flame cutting equipment, the steel plate is not securely fixed on the cutting table. During the cutting process, the steel plate often shifts due to the release of thermal deformation stress or the impact of the cutting airflow. This shift causes frictional contact between the steel plate and the equipment guide rail or other mechanical parts, which in turn forms scratches on the surface of the steel plate, affecting the appearance quality of the product. Summary of the Invention

[0004] The purpose of this application is to provide a flame cutting device for steel plate processing, which can solve the technical problems mentioned in the background art.

[0005] This application provides a flame cutting device for steel plate processing, including a cutting table. A pair of guide rails are supported on the cutting table. A plurality of steel plate support seats are uniformly fixed between the two guide rails on the cutting table. A gantry frame is provided above the steel plate support seats. The gantry frame is slidably connected to the two guide rails. A flame cutter is provided on the gantry frame. An electromagnetic chuck is provided on the steel plate support seats.

[0006] Furthermore, a rubber pad is fixed to the top of the steel plate support, and a receiving groove is provided on the top of the steel plate support. The top opening of the receiving groove penetrates the rubber pad. The electromagnetic chuck is fixed in the receiving groove, and the distance between the top of the electromagnetic chuck and the top of the rubber pad is 3mm to 5mm.

[0007] Furthermore, the cutting table is provided with a drive assembly for driving the gantry frame to move on the guide rail. The drive assembly includes a drive motor, a transmission screw, and a connector. The drive motor is fixed on the cutting table, the transmission screw is rotatably mounted on the cutting table, and the connector is provided with a transmission threaded hole adapted to the transmission screw. The transmission screw is threadedly connected to the connector through the transmission threaded hole, and the connector is fixedly connected to the gantry frame.

[0008] Furthermore, the gantry frame is provided with a sliding groove perpendicular to the moving direction of the gantry frame, and a slider is slidably connected in the sliding groove. The slider is provided with a locking threaded hole, and a locking screw is threadedly connected to the locking threaded hole. One end of the locking screw is fixed with a handle, and the other end of the locking screw can abut against the gantry frame.

[0027] like Figure 1-3 As shown, this application provides a flame cutting device for steel plate processing, including a cutting table 1. A pair of guide rails 2 are mounted on the cutting table 1, and a plurality of steel plate support seats 3 are evenly fixed on the cutting table 1 between the two guide rails 2. A gantry frame 4 is provided above the steel plate support seats 3, and the gantry frame 4 is slidably connected to the two guide rails 2. A flame cutter 5 is provided on the gantry frame 4. An electromagnetic chuck 6 is provided on the steel plate support seats 3. In use, the steel plate to be cut is placed on the steel plate support seat 3 on the cutting table 1 by a chuck trolley. Then, the electromagnetic chuck 6 is energized to generate magnetism, attracting the bottom of the steel plate placed on the steel plate support seat 3, thus fixing the steel plate to the steel plate support seat 3, and pushing the slide rails. The gantry frame 4 and the flame cutter 5 move together. At the same time, the flame cutter 5 is connected to a gas (such as oxygen or acetylene), which is ignited to produce a high-temperature flame. This flame preheats the part of the steel plate to be cut. Once the ignition point is reached, a high-speed oxygen jet is sprayed to burn the steel plate and blow away the molten slag, thus completing the cut. After the cut is completed, the electromagnetic chuck 6 is de-energized and demagnetized, releasing its adsorption on the steel plate. The cut steel plate is then lifted off the cutting table 1 by a chuck crane. The electromagnetic chuck 6 is used to hold the steel plate in place, preventing it from shifting during the cutting process and rubbing against the equipment guide rail 2 or other mechanical parts. This effectively prevents scratches on the surface of the steel plate and ensures the appearance quality of the product.

[0028] like Figure 3As shown, a rubber pad 7 is fixed to the top of the steel plate support 3, and a receiving groove 31 is provided on the top of the steel plate support 3. The top opening of the receiving groove 31 penetrates the rubber pad 7. An electromagnetic chuck 6 is fixed in the receiving groove 31. The distance between the top of the electromagnetic chuck 6 and the top of the rubber pad 7 is 3mm to 5mm. The steel plate is placed on the rubber pad 7. The rubber pad 7 undergoes initial elastic deformation due to pressure, filling the small gap between the bottom surface of the steel plate and the support, thus initially positioning the steel plate. After the electromagnetic chuck 6 is energized, it generates a suction force. Under the action of magnetic force, the steel plate further presses down on the rubber pad 7, increasing the compression of the rubber pad 7. However, the steel plate and the... The electromagnetic chuck 6 always maintains a certain distance, utilizing the flexible support of the rubber pad 7 to avoid scratching the steel plate surface caused by direct rigid contact between the steel plate and the steel plate support 3. Specifically, the rubber pad 7 is made of high-temperature resistant rubber. When cutting the steel plate, the cutting seam is located between two adjacent steel plate support 3 as much as possible to avoid damage to the rubber pad 7 due to high temperature. The distance between the top of the electromagnetic chuck 6 and the top of the rubber pad 7 is 4mm. The electromagnetic chuck 6 does not directly contact the steel plate. The gap design between the top of the electromagnetic chuck 6 and the top of the rubber pad 7 ensures that the steel plate only contacts the rubber pad 7 during the magnetic attraction process, effectively protecting the surface quality of the steel plate.

[0029] like Figure 1 As shown, the cutting table 1 is equipped with a drive assembly 8 for driving the gantry 4 to move on the guide rail 2. The drive assembly 8 includes a drive motor 81, a transmission screw 82, and a connector 83. The drive motor 81 is fixed on the cutting table 1, the transmission screw 82 is rotatably mounted on the cutting table 1, and the connector 83 is provided with a transmission threaded hole adapted to the transmission screw 82. The transmission screw 82 is threadedly connected to the connector 83 through the transmission threaded hole. The connector 83 is fixedly connected to the gantry 4. When the drive motor 81 is powered on and started, the transmission screw 82 rotates, causing the connector 83 to move linearly along the axis of the transmission screw 82. The linear movement of the connector 83 directly drives the gantry 4 to reciprocate along the guide rail 2, thereby realizing the lateral feed movement of the flame cutter 5 on the cutting table 1 and realizing the cutting of the steel plate.

[0030] like Figure 1 and Figure 2As shown, the gantry 4 is provided with a slide groove 41 perpendicular to the moving direction of the gantry 4. A slider 9 is slidably connected in the slide groove 41. The slider 9 is provided with a locking threaded hole, and a locking screw 10 is threadedly connected to the locking threaded hole. One end of the locking screw 10 is fixed with a handle 11, and the other end of the locking screw 10 can abut against the gantry 4. The slider 9 is provided with a lifting adjustment component 12. The flame cutter 5 is connected to the slider 9 through the lifting adjustment component 12. By sliding the slider 9 in the slide groove 41, the flame cutter 5 can be moved longitudinally to meet the cutting needs of different positions on the same steel plate. The lifting adjustment component 12 can drive the flame cutter 5 to move up and down to adapt to the cutting needs of steel plates of different thicknesses. When the slider 9 moves to the required position, the slider 9 can be fixed by rotating the handle 11 to make the other end of the screw abut against the gantry 4. Rotating the handle 11 in the opposite direction will release the screw and make the slider 9 return to the sliding state.

[0031] like Figure 2 As shown, the lifting adjustment assembly 12 includes a lifting cylinder 121 and a mounting base 122. The lifting cylinder 121 is fixed on the slider 9, and the mounting base 122 is fixed on the telescopic end of the lifting cylinder 121. The flame cutter 5 is fixed on the mounting base 122. The lifting cylinder 121 drives the mounting base 122 to move up and down, and the mounting base 122 drives the flame cutter 5 to move up and down.

[0032] like Figure 1 As shown, a positioning baffle 14 is fixed on the cutting table 1. The positioning baffle 14 is flush with the moving direction of the gantry 4. The positioning baffle 14 provides a fixed physical reference and provides a reliable positioning point for the placement of the steel plate.

[0033] like Figure 1-3 As shown, the flame cutting device for steel plate processing in this application also includes a controller (not shown in the figure) and a pressure sensor 15. The pressure sensor 15 is located between the bottom of the rubber pad 7 and the top of the steel plate support 3. The pressure sensor 15 and the electromagnetic chuck 6 are electrically connected to the controller, which is electrically connected to a display screen (not shown in the figure). When the steel plate is placed on the rubber pad 7, the weight of the steel plate is transmitted to the pressure sensor 15 below through the rubber pad 7. The pressure sensor 15 transmits the signal to the controller. The controller receives the signal transmitted by the pressure sensor 15 and processes it. Then, it sends the processed data to the display screen for display at the corresponding position. Since the pressure sensor 15 corresponds one-to-one with the electromagnetic chuck 6, the operator can control the electromagnetic chuck 6 at the corresponding position to be energized by the controller according to the position displayed on the display screen, so that the electromagnetic chuck 6 at the specific position generates suction force to adsorb and fix the steel plate.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
