Description

Technical Field

[0001] This invention relates to the field of plasma flame cutting technology, and in particular to a plasma flame cutting machine and process based on mechanical parking equipment. Background Technology

[0002] Plasma flame cutting machines play a crucial foundational processing role in the manufacturing of mechanical parking equipment. Their core function is to efficiently and precisely cut large quantities of metal sheets for the main structure of the parking equipment. Mechanical parking equipment consists of complex components such as steel frames, vehicle carriers, and lifting channels, all of which require precise cutting from solid steel plates. Plasma cutting technology, with its high energy density and rapid cutting capabilities, can easily handle common materials such as carbon steel and stainless steel, and is particularly adept at cutting medium-thick plates, offering processing efficiency far exceeding traditional flame cutting. It can quickly cut various shapes of connecting plates, reinforcing ribs, brackets, and other key components according to design drawings, ensuring clean cuts and a small heat-affected zone, providing high-quality blanks for subsequent welding and assembly processes. Therefore, plasma cutting machines are core equipment for ensuring manufacturing precision, improving production efficiency, and reducing costs in parking equipment manufacturing.

[0003] Traditional plasma flame cutting machines are widely used in the manufacturing industry, but due to limitations in their structure and working principle, they often suffer from some unavoidable problems. Traditional plasma flame cutting machines have significant limitations in handling diverse material cutting needs. The core issue lies in poor nozzle compatibility: metals of different thicknesses and materials require nozzles of corresponding diameters. Frequent replacements not only disrupt the workflow and significantly reduce processing efficiency but also increase operating costs due to increased spare parts inventory, resulting in poor economic efficiency. Furthermore, the rigid design of the water curtain confinement system means that the cooling and focusing of the plasma flame rely on a fixed water curtain structure, making it impossible to dynamically adjust water flow parameters according to material characteristics. This makes it difficult to balance cutting accuracy and heat-affected zone control, resulting in poor flexibility. This fixed approach also leads to complex maintenance and time-consuming adjustments, further weakening overall processing efficiency and failing to meet the modern industrial demands for efficient, flexible, and low-cost cutting. Summary of the Invention

[0004] In view of the problems of poor nozzle compatibility and inconvenient water curtain constraint in existing technologies, a plasma flame cutting machine based on mechanical parking equipment is proposed.

[0005] Its purpose is to enable the plasma flame cutter to adjust the nozzle diameter and the water curtain coverage area.

[0006] The technical solution of the present invention is a plasma flame cutting machine based on mechanical parking equipment, including a cutting machine body, a plasma nozzle disposed on the top of the cutting machine body, and an adjustment mechanism disposed at the bottom of the plasma nozzle; The adjustment mechanism includes a sleeve disposed at the bottom of the plasma nozzle, several ring arrays of limiting blocks disposed on the inner wall of the bottom of the sleeve, several ring arrays of active plates disposed at intervals between different limiting blocks on the sleeve, a driven plate disposed on the top of the limiting blocks, a drive groove symmetrically opened on the outer wall of the top of the driven plate, a drive block symmetrically disposed on the top of the active plate, a rotating block disposed at the bottom of the sleeve, several ring arrays of sliding grooves opened on the top of the rotating block, a sliding shaft disposed on the outer wall of the top of the active plate, and a spray unit disposed in the middle of the sleeve. The rotating block drives the sliding shaft to move through the sliding groove, and the sliding shaft drives the active plate to move synchronously. The active plate squeezes the driving groove through the driving block, so that the driven plate moves together with the active plate.

[0007] Furthermore, a limiting groove is provided on the top of the limiting block, and a limiting strip is provided on the driven plate near the center of the two driving grooves, with the limiting strip slidably connected to the limiting groove.

[0008] Furthermore, the driven plate is provided with an inclined top plate at its top, and the bottom of the inclined top plate is fixedly connected to the limiting strip.

[0009] Furthermore, the top of the active plate is provided with a straight top plate, the top of which is fixedly connected to two drive blocks, and the top of the sliding shaft is fixedly connected to the bottom of the straight top plate.

[0010] Furthermore, a positioning ring is provided on the inner wall of the rotating block, and a positioning groove is provided at the bottom of the inner wall of the sleeve.

[0011] Furthermore, the spraying unit includes a fixed rod symmetrically arranged in the middle of the sleeve, a housing commonly arranged at the bottom of the fixed rod, a water pipe arranged at the top of the housing, a knob arranged in the middle of the housing, an annular groove opened at the bottom of the knob, a lifting ring arranged in the housing near the bottom of the knob, several pull rods arranged in annular array at the top of the lifting ring, the top of the pull rods being slidably connected to the annular groove, several connecting rods arranged in annular array at the bottom of the lifting ring, several rotating arms arranged in annular array at the bottom of the housing near the bottom of the lifting ring, the middle of the rotating arms being rotatably connected to the pull rods, and a rubber ring arranged at the bottom of the outer wall of the housing, the outer wall of the rubber ring being fixedly connected to the bottom of the rotating arm.

[0012] Furthermore, an inner shell is provided on the inner side of the outer shell, and the inner shell has a tapered shape that expands outward from the bottom.

[0013] Furthermore, the outer wall of the housing near the knob is provided with threads, the inner wall of the knob is threadedly connected to the housing, and the outer wall of the housing near the lifting ring is provided with a number of short pins in a circular array, and the inner wall of the lifting ring is adapted to slide connection with the outer wall of the housing where the short pins are provided.

[0014] Another objective of this invention is to provide a plasma flame cutting process based on mechanical parking equipment manufacturing, the purpose of which is to cut the raw materials to be processed by means of a cutting machine.

[0015] To achieve the above objectives, the present invention provides the following technical solution: a plasma flame cutting process based on the manufacturing of mechanical parking equipment, comprising the following steps: First, adjust the flame nozzle according to the workpiece thickness, rotate the rotating block, and the slide groove drives each sliding shaft to move radially, causing all active plates to converge or diffuse synchronously, and link the driven plate through the drive block, thereby continuously changing the size of the nozzle formed by the active plate and the driven plate to adapt to fine or coarse cutting requirements. Then, adjust the cooling water curtain synchronously by rotating the knob to move it up and down. When the knob moves down, the lever and lifting ring drive the rotating arm to retract the rubber ring and focus the water curtain. When the knob moves up, the rubber ring expands outward and the water curtain diffuses, thus achieving a precise match between concentrated and covered cooling range. Finally, after the operation is completed, turn off the plasma flame and water source, and reset the rotating block and knobs to their initial positions for the next use.

[0016] Furthermore, when adjusting the cooling water curtain, the cooling range should be matched according to the thickness and thermal conductivity characteristics of the material being cut. Diffusion cooling should be used when cutting thick plates or high thermal conductivity materials, while centralized cooling should be used when cutting thin plates or low thermal conductivity materials.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a rinsing mechanism, the nozzle diameter can be adjusted. This design allows the equipment to match the cutting requirements of different materials without interrupting the operation to change the nozzle. The operator can directly adjust the parameters to adapt to changes in plate thickness and material, thereby simplifying the workflow. This function reduces spare parts consumption and maintenance costs, improves the economic efficiency of the equipment, and ensures the continuity of the production process.

[0018] 2. By setting up a switching unit, the water curtain coverage area can be adjusted. This unit can adapt to the shape changes of the plasma flame under different working conditions, providing suitable cooling and constraint effects for the cutting area. The variability of the water curtain shape enhances the equipment's ability to cope with complex working conditions, increases the overall application flexibility, and ensures the stability of cutting quality.

[0019] 3. By setting up a cleaning unit to constrain the water flow, the rubber ring guides the water flow along a predetermined path to form a water curtain with variable coverage. This water flow guidance method ensures precise control of the water curtain shape, enabling it to meet different cutting needs, providing a stable protective barrier for the plasma flame, and optimizing the cutting environment.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-16 This invention provides a plasma flame cutting machine based on a mechanical parking device, comprising a cutting machine body 1, a plasma nozzle 2 fixedly connected to the top of the cutting machine body 1, and an adjustment mechanism 3 installed at the bottom of the plasma nozzle 2. The adjustment mechanism 3 includes a sleeve 31 fixedly connected to the bottom of the plasma nozzle 2, several ring arrays of limiting blocks 32 fixedly connected to the inner wall of the bottom of the sleeve 31, several ring arrays of active plates 33 slidably connected to the sleeve 31 at intervals between different limiting blocks 32, and a driven plate 3 slidably connected to the top of the limiting blocks 32. 4. A drive groove 35 symmetrically opened on the top outer wall of the driven plate 34, a drive block 36 symmetrically fixedly connected to the top of the active plate 33, a rotating block 37 rotatably connected to the bottom of the sleeve 31, a plurality of annular arrays of sliding grooves 38 opened on the top of the rotating block 37, a sliding shaft 39 fixedly connected to the top outer wall of the active plate 33, and an injection unit assembled in the middle of the sleeve 31; the rotating block 37 drives the sliding shaft 39 to move through the sliding groove 38, the sliding shaft 39 drives the active plate 33 to move synchronously, and the active plate 33 squeezes the drive groove 35 through the drive block 36, so that the driven plate 34 moves together with the active plate 33.

[0024] Specifically, when it is necessary to increase the jet diameter of the plasma flame, the rotating block 37 is rotated. Simultaneously, the rotating block 37 compresses the sliding shaft 39 via the sliding groove 38. The sliding shaft 39 is displaced by this compression, and in doing so, it drives the active plate 33 to move as well. The active plate 33 is constrained by two adjacent limiting blocks 32, and therefore can only move linearly. Driven by the sliding shaft 39, the active plate 33 moves away from the axis of the sleeve 31, and in doing so, it drives the driven plate 34 to move along with it via the driving block 36 and the driving groove 35. The driven plate 34 is... Constrained by the limiting block 32, it can only move along the limiting groove of the limiting block 32. Several active plates 33 and several driven plates 34 surround the axis of the sleeve 31 to form a nozzle. The plasma inside the sleeve 31 is ejected through the nozzle. When the active plates 33 and driven plates 34 move away from the axis of the sleeve 31, the diameter of the nozzle increases. When it is necessary to reduce the ejection diameter of the plasma flame, the rotating block 37 is rotated in the opposite direction. At this time, the active plates 33 and driven plates 34 move closer to the axis of the sleeve 31, and the diameter of the nozzle decreases.

[0025] Reference Figures 6-8 A limit groove is provided on the top of the limit block 32, and a limit strip is provided on the driven plate 34 near the center of the two drive grooves 35. The limit strip is slidably connected to the limit groove.

[0026] Specifically, the limiting block 32 is connected to the limiting strip of the driven plate 34 through the limiting groove, thereby constraining the motion degree of freedom of the driven plate 34 so that it can only move along the limiting groove.

[0027] Reference Figure 8 The driven plate 34 is provided with an inclined top plate at the top, and the bottom of the inclined top plate is fixedly connected to the limiting strip.

[0028] Specifically, the inclined top plate of the driven plate 34 and the straight top plate of the active plate 33 cooperate with each other to block the plasma ejected downward from the inside of the sleeve 31.

[0029] Reference Figures 8-11 The top of the active plate 33 is provided with a straight top plate, the top of which is fixedly connected to two drive blocks 36, and the top of the sliding shaft 39 is fixedly connected to the bottom of the straight top plate.

[0030] Specifically, two adjacent active plates 33 are connected to the same driven plate 34 through corresponding drive blocks 36. When the two adjacent driven plates 34 move synchronously, the force will act on the corresponding driven plate 34, thereby causing the driven plate 34 to move.

[0031] Reference Figure 11 and Figure 12 The inner wall of the rotating block 37 is provided with a positioning ring, and the bottom of the inner wall of the sleeve 31 is provided with a positioning groove.

[0032] Specifically, the rotating block 37, under the cooperation of the positioning ring and the positioning groove, is constrained by the sleeve, so that it can only rotate in its original position, and the rotating block 37 constrains the active plate 33, preventing it from moving downward.

[0033] Example 2, refer to Figures 1-16 This is the second embodiment of the present invention, which differs from the first embodiment in that: the spraying unit includes a fixing rod 310 symmetrically fixedly connected to the middle of the sleeve 31, a housing 311 fixedly connected to the bottom end of the fixing rod 310, a water pipe 312 fixedly connected to the top of the housing 311, a knob 313 threadedly connected to the middle of the housing 311, an annular groove 314 formed at the bottom of the knob 313, a lifting ring 315 slidably connected to the housing 311 near the bottom of the knob 313, and several annular... A pull rod 316 is fixedly connected to the top of the lifting ring 315. The top end of the pull rod 316 is slidably connected to the ring groove 314. Several ring arrays are rotatably connected to the connecting rod 317 at the bottom of the lifting ring 315. Several ring arrays are rotatably connected to the rotating arm 318 near the bottom of the lifting ring 315 on the outer shell 311. The middle part of the rotating arm 318 is rotatably connected to the pull rod 316. A rubber ring 319 is fixedly connected to the bottom of the outer wall of the outer shell 311. The outer wall of the rubber ring 319 is fixedly connected to the bottom end of the rotating arm 318.

[0034] Specifically, after connecting the water pipe 312 to the water source, the water flow will enter the interior of the outer casing 311 through the water pipe 312 and spray out in a ring shape from the bottom of the outer casing 311, forming a water curtain. When the water flow passes through the inner shell of the outer casing 311, it is guided by its conical inclined wall. As the water flow falls, it moves away from the axis of the outer casing 311 and then impacts the inner wall of the rubber ring 319. Guided by the rubber ring 319, it forms the final spray direction. When it is necessary to adjust the cone of the water curtain to increase the coverage area, the knob 313 is turned upward. As the knob 313 moves upward, the lifting ring 315 moves upward through the pull rod 316. As the lifting ring 315 moves upward, the connecting rod 317 moves upward. As the connecting rod 317 moves upward, the rotating arm 318 is pulled. Because the top of the rotating arm 318 is constrained by the outer shell 311, after being pulled by the connecting rod 317, the rotating arm 318 will rotate with its bottom end facing the direction of force, centered on the connection point with the outer shell 311. When the bottom ends of several rotating arms 318 are simultaneously pulled upward by the corresponding connecting rod 317, the rubber ring 319 will expand outward. After the rubber ring 319 expands, the water flow will spray along the direction of the inner wall contour of the rubber ring 319, increasing the coverage area of ​​the water curtain. When it is necessary to reduce the coverage area of ​​the water curtain, the lifting ring 315 is moved downward by the knob 313, so that the connecting rod 317 can rotate the arm 318 to push the rubber ring 319 inward. When the bottom opening of the rubber ring 319 is smaller than the top opening, the water curtain sprays in the direction closer to the axis of the outer shell 311, thus reducing the coverage area.

[0035] Reference Figure 13 An inner shell is provided on the inner side of the outer shell 311, and the inner shell is tapered with the bottom end expanding outward.

[0036] Specifically, as the water flows from the inside of the outer casing 311 to the outside, its direction is guided in turn by the inner casing and the rubber ring 319.

[0037] Reference Figure 13 and Figure 14 The outer wall of the housing 311 near the knob 313 is provided with threads, and the inner wall of the knob 313 is threadedly connected to the housing 311. The outer wall of the housing 311 near the lifting ring 315 is provided with a number of short pins in a circular array, and the inner wall of the lifting ring 315 is adapted to slide connection with the outer wall of the housing 311 where the short pins are provided.

[0038] Specifically, as the knob 313 rotates, it will move along the axis of the outer casing 311 under the action of the thread. The lifting ring 315 is constrained by the short pin and can only move up and down along the axis of the outer casing 311. The rest of the structure is the same as that of Embodiment 1.

[0039] Based on embodiments 1-2, the working principle of this invention is as follows: When it is necessary to adjust the plasma flame jet diameter, rotating the rotating block 37 causes the active plate 33 and the sliding shaft 39 to be displaced by the sliding groove 38. Simultaneously, the active plate 33 moves, driving the two connected driven plates 34 to move together. When the active plate 33 drives the driven plates 34 to move away from the axis of the sleeve 31, the nozzle diameter formed by the active plate 33 and the driven plates 34 increases. When the active plate 33 drives the driven plates 34 to move closer to the axis of the sleeve 31, the nozzle diameter formed by the active plate 33 and the driven plates 34 decreases. When adjusting the taper of the water curtain, the knob 313 is rotated to move the lifting ring 315 up and down via the pull rod 316. When the lifting ring 315 moves up, the rubber ring 319 expands outward through the connecting rod 317 and the rotating arm 318. At this time, when the water source is turned on, the water flow will be guided by the inner shell and impact the inner wall of the rubber ring 319. Then, guided by the inner wall of the rubber ring 319, it will be sprayed out. The greater the outward expansion of the rubber ring 319, the larger the coverage area of ​​the water curtain. Conversely, when the lifting ring 315 moves down, the rotating arm 318 controls the rubber ring 319 to retract inward. At this time, when the water flow is sprayed under the guidance of the inner wall of the rubber ring 319, its coverage area is reduced.

[0040] Example 3, referring to Figures 1-16 The third embodiment of the present invention provides a plasma flame cutting process based on the manufacturing of mechanical parking equipment, comprising the following steps: S1. First, adjust the flame nozzle according to the workpiece thickness. Rotate the rotating block 37, and the sliding groove 38 drives each sliding shaft 39 to move radially, causing all active plates 33 to converge or diffuse synchronously. The driven plate 34 is linked through the driving block 36, thereby continuously changing the size of the nozzle formed by the active plate 33 and the driven plate 34 to adapt to fine or coarse cutting requirements. By adjusting the nozzle diameter of the plasma flame, different cutting requirements can be adapted.

[0041] S2, then, synchronously adjust the cooling water curtain by rotating the knob 313 to move it up and down. When the knob 313 moves down, the lever 316 and the lifting ring 315 drive the rotating arm 318 to retract the rubber ring 319 and focus the water curtain. When the knob 313 moves up, the rubber ring 319 expands outward and the water curtain diffuses. This achieves a precise match between the cooling range and the coverage. By adjusting the coverage of the water curtain, the plasma flame is constrained, and the heat-affected zone during cutting is controlled.

[0042] S3. Finally, after the operation is completed, turn off the plasma flame and water source, and reset the rotating block 37 and knob 313 to their initial state for the next use. If the raw material cutting requirements are the same as the previous one, the reset is not necessary.

[0043] S4. When adjusting the cooling water curtain, the cooling range should be matched according to the thickness and thermal conductivity characteristics of the material being cut. Diffusion cooling should be used when cutting thick plates or high thermal conductivity materials, while centralized cooling should be used when cutting thin plates or low thermal conductivity materials. The water curtain adjustment function increases the practicality and flexibility of the equipment.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

When the knob (313) moves down, the lever (316) and the lifting ring (315) drive the rotating arm (318) to make the rubber ring (319) retract and the water curtain focus. When the knob (313) moves up, the rubber ring (319) expands outward and the water curtain diffuses, thereby achieving a precise match from concentrated to covered cooling range. Finally, after the operation is completed, turn off the plasma flame and water source, and reset the rotating block (37) and knob (313) to their initial state for the next use.

9. The plasma flame cutting process based on the manufacturing of mechanical parking equipment according to claim 8, characterized in that, When adjusting the cooling water curtain, the cooling range should be matched according to the thickness and thermal conductivity characteristics of the material being cut. Diffusion cooling should be used when cutting thick plates or high thermal conductivity materials, while centralized cooling should be used when cutting thin plates or low thermal conductivity materials.
