Description

Technical Field

[0001] This utility model relates to the field of steel plate cutting technology, specifically to an integrated steel plate cutting device. Background Technology

[0002] Steel plates are flat, rectangular steel products made by pouring molten steel, cooling, and pressing it. They can be directly rolled or cut from wide steel strips. Steel plates are classified by thickness: thin steel plates <4 mm (thinnest 0.2 mm), medium-thick steel plates 4-60 mm, and extra-thick steel plates 60-115 mm. Steel plates are also classified by rolling process: hot-rolled and cold-rolled.

[0003] Manual cutting relies on the operator's experience and skills, making it difficult to guarantee cutting accuracy. Problems such as uneven cutting lines and inconsistent cut widths are common. Moreover, it is labor-intensive and has low production efficiency, making it unable to meet the needs of large-scale production. While simple mechanical cutting improves production efficiency to some extent, it lacks flexibility and precision and is often powerless when cutting steel plates with complex shapes. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing an integrated steel plate cutting device.

[0005] The specific technical solution is as follows: An integrated steel plate cutting device includes a placement plate, a driving mechanism is provided on the top of the placement plate, a mounting base is provided on the right side of the driving mechanism, a gun is provided at the bottom of the mounting base, and an electric push rod is fixedly installed on the top of the mounting base. The output end of the electric push rod passes through the mounting base and is fixedly connected to the top of the gun. The drive mechanism includes an arched mounting frame disposed on the outside of the placement plate. An electrical control box is fixedly installed on the top of the front side of the arched mounting frame. A ribbon cable is electrically connected to the rear side of the electrical control box. The end of the ribbon cable is fixedly connected to the top of the mounting base. Guide wheels are fixedly installed on both sides of the bottom of the arched mounting frame.

[0006] As a preferred embodiment of this utility model, the front and rear sides of the placement plate are provided with first limiting grooves, and a first driving block is slidably connected inside the first limiting groove. One side of the first driving block is fixedly connected to the inner side of the arched mounting bracket.

[0007] As a preferred embodiment of this utility model, two first servo motors are fixedly installed on the right side of the placement plate. The output shaft of the first servo motor is fixedly installed with a first ball screw. The first ball screw passes through the interior of the first limiting groove and is connected to the first drive block by ball bearings.

[0008] As a preferred embodiment of this utility model, the top of the arched mounting bracket is provided with a second limiting groove, and a second driving block is slidably connected inside the second limiting groove. The right side of the second driving block is fixedly connected to the left side of the mounting base.

[0009] As a preferred embodiment of this utility model, a second servo motor is fixedly installed on the front side of the arched mounting bracket, and a second ball screw is fixedly installed on the output shaft of the second servo motor. The second ball screw passes through the interior of the second limiting groove and is connected to the second drive block by ball bearings.

[0010] As a preferred embodiment of this utility model, a conduit is provided on the rear side of the mounting base, and the end of the conduit is connected to the top of the gun.

[0011] As a preferred embodiment of this utility model, a threaded connection end is embedded on the front side of the electrical control box, a wire is fixedly installed on the right side of the electrical control box, the rear side of the threaded connection end extends into the interior of the electrical control box and connects to the connecting pipe inside the ribbon cable, and the conduit communicates with the connecting pipe inside the ribbon cable.

[0012] This utility model has the following beneficial effects: 1. "Left and right + forward and backward" coordinated movement breaks through the limitations of traditional cutting. The device drives the arched mounting frame to move left and right along the first limiting groove via a "first servo motor + first ball screw" and drives the mounting base to move back and forth along the second limiting groove via a "second servo motor + second ball screw". The two work together to enable the gun to move along any trajectory in a two-dimensional plane. Compared with traditional manual cutting or single-direction cutting equipment, this device can accurately cut complex workpieces, greatly improve the yield, and reduce steel plate waste caused by insufficient precision.

[0013] Compared to gear and belt drives, ball screw drives have the advantages of "no backlash and low wear". They can maintain high precision even after long-term use, avoiding the precision decline caused by wear in traditional drives, and are suitable for scenarios with high precision requirements.

[0014] 2. The limiting structure ensures stable movement and prevents cutting deviation. The sliding engagement of the first limiting groove with the first driving block and the second limiting groove with the second driving block provides precise guidance for the movement of the arched mounting frame and mounting base, preventing the gun from deviating due to vibration during steel plate cutting. At the same time, the guide wheels at the bottom of the arched mounting frame provide auxiliary support, reducing frictional resistance during movement and ensuring a smooth movement process. This further ensures that the cutting trajectory is consistent with the preset path, making it especially suitable for long-distance cutting and avoiding the problem of "the more you cut, the more off-center" in traditional cutting.

[0015] 3. High-temperature plasma for rapid cutting of steel plates of various materials and thicknesses. The compressed air delivered through the conduit interacts with the electric current to generate high-temperature plasma, which can instantly melt steel plates. The cutting speed is faster than traditional oxyacetylene cutting, and a single person can complete the cutting of large-sized steel plates, significantly shortening the processing cycle.

[0016] The electric push rod drives the gun to rise and fall, reducing burrs on the cut caused by plasma dispersion; when cutting thick steel plates, the gun height is raised to ensure plasma penetration, avoiding the problem of "uneven cutting of thin steel plates and incomplete cutting of thick steel plates" caused by traditional fixed-height guns, making it suitable for processing steel plates of various thicknesses in building steel structures, machinery manufacturing and other scenarios.

[0017] 4. Low energy consumption and environmentally friendly, reducing processing costs. Compared to laser cutting, plasma cutting consumes less energy and does not require expensive laser generators, reducing equipment procurement costs by more than 50%. Compared to oxyacetylene cutting, it does not consume flammable and explosive gases such as acetylene and oxygen, requiring only compressed air and electricity. It also avoids safety hazards and environmental pollution caused by gas leaks, conforming to the concept of green processing. Attached Figure Description

[0024] Example The integrated steel plate cutting device provided in this embodiment, such as Figures 1-4 As shown, the device includes a placement plate 1, a drive mechanism 3 on the top of the placement plate 1, a mounting base 2 on the right side of the drive mechanism 3, a gun 9 at the bottom of the mounting base 2, and an electric push rod 4 fixedly mounted on the top of the mounting base 2. The output end of the electric push rod 4 passes through the mounting base 2 and is fixedly connected to the top of the gun 9. The placement plate 1 is used to install the drive mechanism 3 and place the steel plate to be cut, so that it can be cut by the drive mechanism 3. The drive mechanism 3 is used to cut the steel plate placed on the top of the placement plate 1, and can be moved and adjusted according to the cutting needs, so as to cut the steel plate into different shapes. The drive mechanism 3 includes an arched mounting bracket 301 located on the outside of the placement plate 1. An electrical control box 8 is fixedly mounted on the top of the front side of the arched mounting bracket 301. A ribbon cable 5 is electrically connected to the rear side of the electrical control box 8. The end of the ribbon cable 5 is fixedly connected to the top of the mounting base 2. Guide wheels 303 are fixedly mounted on both sides of the bottom of the arched mounting bracket 301. The electrical control box 8 is used to control the drive mechanism 3, thereby driving the drive mechanism 3 to move the gun 9 to cut the steel plate. The guide wheels 303 are used to support the arched mounting bracket 301 and move the arched mounting bracket 301 to cut the steel plate into different shapes. The electrical control box 8 integrates a controller, including but not limited to model LK3U-14, for digital control of the whole system and information exchange with the outside world. Since this control method is existing technology, it is not described in detail in the specification of this solution.

[0025] The front and rear sides of the placement plate 1 are provided with first limiting grooves 302. A first driving block 304 is slidably connected inside the first limiting groove 302. One side of the first driving block 304 is fixedly connected to the inner side of the arched mounting frame 301. The first limiting groove 302 and the first driving block 304 are provided to limit the arched mounting frame 301.

[0026] Two first servo motors 306 are fixedly installed on the right side of the placement plate 1. The output shaft of the first servo motor 306 is fixedly installed with a first ball screw 305. The first ball screw 305 passes through the interior of the first limiting groove 302 and is connected to the first drive block 304 by ball bearings. The cooperation between the first servo motor 306, the first ball screw 305 and the first drive block 304 enables the arched mounting frame 301 to move left and right, thereby driving the gun 9 to move and cut the steel plate.

[0027] The top of the arched mounting bracket 301 is provided with a second limiting groove 307. A second driving block 309 is slidably connected inside the second limiting groove 307. The right side of the second driving block 309 is fixedly connected to the left side of the mounting base 2. The second limiting groove 307 and the second servo motor 308 are used to install the mounting base 2. The mounting base 2 is used to install the electric push rod 4, thereby driving the gun 9 to rise and fall, so as to cut steel plates of different thicknesses.

[0028] A second servo motor 308 is fixedly installed on the front side of the arched mounting bracket 301. A second ball screw 310 is fixedly installed on the output shaft of the second servo motor 308. The second ball screw 310 passes through the interior of the second limiting groove 307 and is connected to the second drive block 309 by ball bearings. The second servo motor 308, the second ball screw 310 and the second drive block 309 are configured to drive the mounting base 2 to move the gun 9 back and forth to cut the steel plate.

[0029] A conduit 10 is provided on the rear side of the mounting base 2. The end of the conduit 10 is connected to the top of the gun 9. The conduit 10 is provided to blow out air and generate an electric arc with the current to form plasma to cut the steel plate.

[0030] The front side of the electrical control box 8 is fitted with a threaded connection end 6, and the right side of the electrical control box 8 is fixedly installed with a wire 7. The rear side of the threaded connection end 6 extends into the interior of the electrical control box 8 and connects with the connecting pipe inside the ribbon cable 5. The conduit 10 is connected to the connecting pipe inside the ribbon cable 5. The threaded connection end 6 is set to connect with an external gas supply source. The wire 7 is set to make an electrical connection to the steel plate to be cut to realize the current loop. The connecting pipe integrated inside the ribbon cable 5 is used to guide and transport the gas.

[0031] Working principle: 1. External Connections and Parameter Presets The operator first completes the connection between the equipment and external resources: connect the threaded connection end 6 on the front of the electrical control box 8 to an external compressed air source such as an air compressor to ensure that compressed air can be stably delivered to the conduit 10; connect one end of the wire 7 on the right side of the electrical control box 8 to the steel plate to be cut, and connect the other end to the power module inside the electrical control box to form a current loop of "electrical control box-wire-steel plate".

[0032] Preset cutting parameters through the operation interface of the electrical control box 8: set the plasma cutting current and compressed air flow according to the material and thickness of the steel plate, and import the cutting trajectory drawing to complete the parameter configuration before cutting.

[0033] 2. Placement and positioning of steel plates Place the steel plate to be cut stably on top of the placement plate 1, and fix the steel plate with the positioning clamps on the edge of the placement plate to prevent the steel plate from shifting during the cutting process; adjust the position of the steel plate according to the preset cutting trajectory so that the cutting starting point is aligned with the initial position of the gun 9 to complete the steel plate positioning.

[0034] 3. Adjustment of left and right movement of the arched mounting bracket The control box 8 issues a "move left or right" command, which drives the two first servo motors 306 on the right side of the placement plate 1 to start. The output shaft of the first servo motor 306 drives the first ball screw 305 to rotate. The first ball screw forms a helical transmission with the first drive block 304 through the balls, which converts the rotational motion of the motor into the linear motion of the first drive block. The first drive block 304 slides along the first limiting groove 302 of the placement plate 1, which drives the arched mounting bracket 301 fixed thereto to move left and right synchronously, thereby enabling the gun 9 on the arched mounting bracket to move in the left and right direction.

[0035] The guide wheels 303 at the bottom of the arched mounting bracket 301 roll synchronously with the mounting bracket, assisting in supporting the weight of the mounting bracket and ensuring that the mounting bracket moves smoothly, avoiding deviation caused by uneven weight distribution.

[0036] 4. Adjustment of the forward and backward movement of the mounting base When the gun 9 needs to move in the front-back direction, the control box 8 drives the second servo motor 308 on the front side of the arched mounting bracket 301 to start; the output shaft of the second servo motor drives the second ball screw 310 to rotate, and the second ball screw transmits power to the second drive block 309 through the balls, so that the second drive block slides along the second limiting groove 307 on the top of the arched mounting bracket; the second drive block 309 drives the mounting base 2 fixed thereto to move back and forth synchronously, and the gun 9 moves along the mounting base in the front-back direction.

[0037] The coordinated action of the first and second servo motors enables the gun 9 to move along a preset trajectory in a two-dimensional plane. For example, when cutting a circular trajectory, the control box controls the two servo motors to drive alternately according to the circular motion law, ensuring that the gun trajectory is completely consistent with the preset drawing.

[0038] 5. Compressed air delivery and electric arc generation The electrical control box 8 synchronously starts the cutting program: external compressed air enters the electrical control box through the threaded connection end 6, and is then delivered to the inside of the gun 9 through the conduit 10 at the bottom of the cable 5; at the same time, the electrical control box outputs high-voltage current to the gun, and the current is released through the gun electrode to form an electric arc with the steel plate to be cut; the compressed air is ionized into high-temperature plasma under the high temperature of the electric arc, and the plasma has extremely high thermal energy and kinetic energy, which is ejected at high speed from the gun nozzle.

[0039] 6. Steel plate cutting and trajectory following The high-speed plasma instantly melts the metal at the cutting point of the steel plate, while compressed air blows the molten metal slag away from the cut, forming a smooth cutting surface. During this process, the electrical control box controls the first and second servo motors in real time to drive the gun to move along the preset trajectory. The moving speed matches the plasma cutting speed until the cutting trajectory of the entire steel plate is completed.

[0040] During the cutting process, the electrical control box monitors the cutting parameters in real time. If any abnormality occurs, an alarm is immediately issued and the cutting is paused to avoid problems such as "incomplete cut" or "excessive burrs on the cut surface" and to ensure the cutting quality.

[0041] 7. Cutting completed and equipment stopped Once the cutting torch completes the preset cutting trajectory, the control box automatically stops the plasma cutting and simultaneously controls the first and second servo motors to drive the torch back to its initial position; the electric push rod 4 retracts, raising the torch to a safe height to complete one cutting operation.

[0042] 8. Steel plate removal and equipment maintenance The operator turns off the equipment power, disconnects the external air source from the wires, and removes the cut steel plate; checks the nozzle of the cutting torch for wear, cleans the molten metal slag on the placement plate 1, and prepares for the next cutting operation; if continuous cutting is required, simply repeat the "steel plate placement-positioning-start cutting" process without reconfiguring the parameters.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
