Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting machine for producing multi-layer metal-pressed stainless steel pots. Background Technology

[0002] This laser cutting machine for multi-layer composite stainless steel pot production is specially designed for cutting multi-layer composite plates made of composite stainless steel and aluminum heat-conducting layers. Utilizing a high-rigidity annealed bed and a high-precision servo CNC system, it outputs micron-level positioning accuracy. A fiber laser delivers a high-density laser beam, and high-purity nitrogen assists in cutting. It can quickly and non-contactly cut round blanks, irregularly shaped edging plates, and composite substrates for the pot bottom. The cutting kerf is narrow, and the heat-affected zone is minimal, effectively preventing delamination, oxidation, and edge deformation of the multi-layer composite metal. The cut is smooth and burr-free, requiring no additional grinding. It is compatible with batch cutting of multi-layer composite metal coils and flat sheets of varying thicknesses and supports one-click switching of multiple pot body contour programs. This significantly improves the consistency and efficiency of blank processing before pressing, and stably ensures the processing accuracy of subsequent metal hot pressing and stretching forming processes. It is the core precision cutting equipment for automated production lines of multi-layer composite stainless steel pots.

[0003] However, existing laser cutting machines only contact the sheet metal at the grid position, leaving the rest of the worktable suspended. Without planar constraints during thermal stress release, deformation develops freely. During continuous cutting of the entire sheet, as heat accumulates, the sheet metal exhibits localized arching and edge warping, exceeding the stable range of capacitance height. This results in incomplete cuts and increased slag buildup. Furthermore, during laser cutting, molten metal is blown to the lower surface of the sheet metal by the auxiliary airflow, where it cools and solidifies, forming slag nodules. The blank then needs to undergo subsequent cold forming processes such as stretching, spinning, and edge rolling. The slag on the bottom surface is a hard protrusion that directly disrupts the uniformity of stress during the forming process.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing laser cutting machine used for producing multi-layer metal-pressed stainless steel pots. Summary of the Invention

[0008] Preferably, the pressing assembly includes a lifting frame disposed within a movable seat, a movable plate symmetrically fixed at the bottom end of the lifting frame, a plurality of sliders slidably connected at equal distances within the movable plate, a guide rod fixed on one side of each slider, a guide plate slidably connected to the guide rod, a connecting rod fixed at the bottom end of each slider, a movable rod slidably connected within the connecting rod, and the bottom end of the movable rod rotatably connected to a roller.

[0009] Preferably, an electric push rod is fixed at the top of the lifting frame, the bottom of the lifting frame is fixedly connected to the first sliding rod, and the movable seat has a cavity that cooperates with the movement of the lifting frame.

[0010] Preferably, the lifting frame is slidably connected to the base, the moving plate is slidably limited to the inner wall of the base, and the moving plate has a cavity that cooperates with the movement of the slider.

[0011] Preferably, the guide plate has a Z-shaped inclined groove and a straight groove that move with the guide rod, the connecting rod has a cavity that moves with the moving rod, and a compression spring is fixed between the top end of the moving rod and the bottom end of the inner wall of the cavity.

[0012] Preferably, the slag scraping assembly includes a lifting component disposed within a rotating column. A fixed column is fixed to the bottom end of the lifting component. A threaded rod is rotatably connected within the fixed column. A turntable is fixed to the bottom end of the threaded rod. Multiple limiting components are slidably connected at equal angles within the turntable. The bottom ends of the limiting components are fixedly connected to a support base. A slide rail is slidably connected to the support base. A limiting rod is slidably connected to the lifting component. The limiting rod is fixedly connected to a fixed frame.

[0013] Preferably, the limiting rod is fitted with a buffer spring, one end of which is fixedly connected to the fixed frame, and the other end of which is fixedly connected to the lifting component.

[0014] Preferably, the fixed column has a movable threaded groove for the threaded rod, and the turntable has a movable guide groove for the limiting component.

[0015] Preferably, the turntable is rotatably connected to the slide rail, the slide rail is fixedly connected to the inner wall of the rotating column, and the slide rail has a cavity that moves to cooperate with the support seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention uses a roller and a moving rod for rotational connection. The moving rod is nested inside the connecting rod, and a compression spring is set between the two cavities to form a floating elastic holding. When the cutting head descends to calibrate the height, the roller contacts the top surface of the plate before the nozzle. As the moving seat continues to descend, the spring is compressed and stores energy, automatically forming a stable elastic preload. During the cutting process, the roller rolls along both sides of the cut, forming a rigid constraint with the support seat below. The elastic preload can tightly press the interlayer interface of the cutting area, offsetting the internal expansion force generated by the vaporization of the aluminum layer at the moment of perforation, avoiding interlayer bulging, delamination, and aluminum slag seepage. The rolling holding throughout the process can offset the warping deformation of the plate caused by the thermal stress of cutting.

[0018] 2. This invention uses a fixed column with an internal threaded groove at the bottom of the second sliding rod to form a helical transmission pair by meshing with the threaded rod. The bottom of the threaded rod is connected to a turntable with a helical guide groove. The turntable drives the support seat to slide along the radial slide rail through the limiting component. When the top roller adjusts the distance, the bottom support seat adjusts its position radially in sync, always aligning directly below the cut, achieving precise alignment of the upper and lower pressing and support. The support position expands precisely outward with the pot diameter, which can effectively support the narrow excess material outside the cut, reduce the risk of the cutting head collision caused by the excess material arching due to heat, reduce the probability of abnormal equipment shutdown, and improve the stability of continuous production. In addition, the motor drives the rotating column to rotate circumferentially, and the support seat rotates synchronously. The hard cutting edge at the top and the bottom cut of the pot blank produce relative circumferential motion, completely scraping away the slag before it has completely cooled and hardened.

[0019] 3. This invention utilizes a symmetrical groove design to allow all sliders to spread out or retract synchronously at equal intervals along the circumference. This, in turn, drives the sets of elastic holding rollers below to synchronously adjust their holding distance. The equidistant distribution of multiple rollers can form a uniform holding force along the entire circumference of the circular cut, avoiding insufficient local force caused by single or double roller holding. After cutting, the bottom of the waste area loses its support and is suspended in mid-air. The compressed spring releases its elastic potential energy to push the moving rod downward, applying a thrust from top to bottom to break the micro-connection point, thus achieving automatic detachment of the waste. The spring thrust from top to bottom replaces the traditional manual bending and breaking method, avoiding interlayer tearing, burr flanging, and edge deformation caused by bending and shearing forces. It fully preserves the interlayer bonding strength at the cut, significantly reducing the risk of cracking in subsequent stretching and curling processes. Attached Figure Description

[0022] Please see Figures 1 to 9This invention provides a technical solution: a laser cutting machine for producing multi-layer metal-pressed stainless steel pots, comprising a main body 1, a movable seat 2 at the top of the main body 1, a cutting head 3 at the bottom of the movable seat 2, bases 4 fixed on both sides of the cutting head 3, a pressing component inside the base 4, a roller 6 at the bottom of the pressing component, and the pressing component presses the pot blank to prevent warping and deformation of the cut edge of the pot blank, a first sliding rod 7 fixed at one end of the pressing component, the first sliding rod 7 being slidably connected to a first oil tank 8, a rotating column 9 at the worktable of the main body 1, a motor fixed at one end of the rotating column 9, a fixed frame 14 fixed inside the rotating column 9, a slag scraping component inside the rotating column 9, and multiple support seats 13 fixed at equal angles outside the slag scraping component, and the slag scraping component drives the support seats 13 to move to remove slag nodules on the lower surface of the cut pot blank, a second sliding rod 11 fixed at one end of the slag scraping component, the second sliding rod 11 being slidably connected to a second oil tank 10.

[0023] In practice, during cutting, the moving seat 2 descends, causing the roller 6 to elastically press the plate, effectively preventing warping and delamination of the pot blank during cutting. The pressing component can drive the first sliding rod 7 to slide in the first oil tank 8, and through hydraulic transmission, the second sliding rod 11 in the second oil tank 10 is linked, driving the slag scraping component to drive the support seat 13 to adaptively adjust its position according to the size of the pot blank and support it directly in front of the cutting seam, ensuring stable cutting. After cutting, the pressing component releases its spring energy to push off the waste material, and then the motor drives the rotating column 9 to rotate the support seat 13. The slag scraping component quickly removes the slag nodules on the lower surface of the pot blank. The entire process relies on mechanical linkage to achieve integrated operation of pressing, adaptive support, automatic material dropping, and slag scraping.

[0024] As a further embodiment of the present invention, the bottom end of the first oil tank 8 is fixedly connected to the inner wall of the cavity opened in the movable seat 2, the second oil tank 10 is fixedly connected to the inner wall of the cavity opened in the rotating column 9, and the first oil tank 8 and the second oil tank 10 are fixedly connected by a hose.

[0025] In practice, when the moving seat 2 presses down and drives the pressing component to adjust the distance between the rollers 6 and the pressing height, it will drive the first sliding rod 7 to slide within the first oil tank 8, squeezing the internal oil into the second oil tank 10 through the hose, and pushing the second sliding rod 11 to operate in conjunction, thereby driving the slag scraping component and the support seat 13 to adjust their positions synchronously and adaptively, so as to automatically match the support position according to the size of the pot blank, and complete the stable cutting with the elastic pressing of the rollers 6. After the cutting is completed, the waste material will be automatically dropped and the slag on the bottom surface of the pot blank will be scraped off in conjunction.

[0026] As a further embodiment of the present invention, the pressing assembly includes a lifting frame 501 disposed in the movable seat 2. A movable plate 502 is symmetrically fixed at the bottom end of the lifting frame 501. A plurality of sliders 503 are slidably connected at equal distances in the movable plate 502. A guide rod 504 is fixed on one side of the slider 503. A guide plate 505 is slidably connected to the guide rod 504. A connecting rod 506 is fixed at the bottom end of the slider 503. A movable rod 508 is slidably connected in the connecting rod 506. The bottom end of the movable rod 508 is rotatably connected to the roller 6.

[0027] In practice, the pressing assembly moves vertically through the lifting frame 501 inside the moving seat 2, which drives the symmetrically fixed moving plate 502 at the bottom to move synchronously. This causes multiple sliders 503, which are evenly distributed inside the moving plate 502, to slide. The sliders 503 slide precisely along the guide plate 505 with the help of the guide rods 504 fixed on the side, converting the vertical movement into radial horizontal displacement. This allows multiple groups of sliders 503 to spread out or retract at equal intervals. The connecting rod 506 at the bottom of the slider 503 adjusts its distance synchronously, which drives the internally slidingly connected moving rod 508 and the roller 6 rotatably connected at the bottom to adjust their distance synchronously. This adapts to the cutting of stainless steel pot blanks of different diameters. Combined with the spring elastic structure, it achieves uniform elastic pressing of the plate, effectively suppressing the thermal deformation and interlayer peeling of the plate during the cutting process, and ensuring the cutting accuracy and integrity of the plate.

[0028] As a further embodiment of the present invention, an electric push rod is fixed at the top of the lifting frame 501, the bottom of the lifting frame 501 is fixedly connected to the first sliding rod 7, and the movable seat 2 has a cavity that cooperates with the movement of the lifting frame 501.

[0029] In practice, the electric push rod drives the lifting frame 501 to move vertically within the cavity reserved in the movable seat 2. On the one hand, the lifting frame 501 drives the lower pressing component to synchronously adjust the spacing of the rollers 6 to adapt to different specifications of pot blanks and elastically press the plate. On the other hand, it drives the first sliding rod 7 connected to the bottom to move synchronously, pushing the oil inside the first oil tank 8 to be transported to the second oil tank 10 through the hose. The hydraulic linkage drives the support seat 13 to synchronously and adaptively adjust its position. The upper and lower mechanisms work together to suppress the thermal warping of the plate, prevent the delamination between the layers of the multi-layer composite board, and ensure the quality of the cut section.

[0030] As a further embodiment of the present invention, the lifting frame 501 is slidably connected to the base 4, the moving plate 502 is slidably connected to the inner wall of the base 4, and the moving plate 502 has a cavity that cooperates with the slider 503.

[0031] In practice, the lifting frame 501 is slidably assembled with the base 4. When the lifting frame 501 moves vertically, it drives the movable plate 502 connected to it to slide along the inner wall of the base 4. The movable plate 502 has a cavity inside which the slider 503 can move. The slider 503 can cooperate with the guide plate 505 in the cavity to achieve radial synchronous extension and contraction, thereby synchronously adjusting the spacing of each set of rollers 6, so as to achieve uniform elastic pressing on multi-layer composite plates of different sizes, effectively suppressing cutting thermal deformation and interlayer peeling.

[0032] As a further embodiment of the present invention, the guide plate 505 is provided with a Z-shaped inclined groove and a straight groove that move in conjunction with the guide rod 504, the connecting rod 506 is provided with a cavity that moves in conjunction with the moving rod 508, and a compression spring 507 is fixed between the top end of the moving rod 508 and the bottom end of the inner wall of the cavity.

[0033] In specific implementation, the guide plate 505 has a Z-shaped inclined groove and a straight groove for the guide rod 504 to slide. When the guide rod 504 moves with the slider 503, it slides along the groove, converting the vertical movement of the lifting frame 501 into the radial synchronous displacement of the slider 503, and synchronously adjusting the spacing of the rollers 6 to adapt to different pot blanks. The connecting rod 506 has a cavity inside to accommodate the sliding of the moving rod 508. A compression spring 507 is installed between the bottom of the cavity and the top of the moving rod 508. When the cutting head 3 moves down, the rollers 6 press against the plate, causing the moving rod 508 to slide up and the compression spring 507 to generate a constant elastic pre-pressure, which evenly presses the composite plate, offsets the cutting thermal stress, and prevents interlayer delamination and plate warping deformation.

[0034] As a further embodiment of the present invention, the slag scraping assembly includes a lifting member 121 disposed in a rotating column 9. A fixing column 122 is fixed to the bottom end of the lifting member 121. A threaded rod 123 is rotatably connected inside the fixing column 122. A turntable 124 is fixed to the bottom end of the threaded rod 123. A plurality of limiting members 125 are slidably connected at equal angles inside the turntable 124. The bottom end of the limiting member 125 is fixedly connected to a support base 13. A slide rail 126 is slidably connected to the support base 13. A limiting rod 127 is slidably connected to the lifting member 121. The limiting rod 127 is fixedly connected to a fixing frame 14.

[0035] In practice, hydraulic transmission drives the lifting component 121 to slide vertically along the limiting rod 127 connected to the fixed frame 14. The fixed column 122 at the bottom of the lifting component 121 moves with it and drives the internally fitted threaded rod 123 to rotate. The threaded rod 123 drives the bottom turntable 124 to rotate synchronously. The turntable 124 drives each support seat 13 to slide radially synchronously along the slide rail 126 by relying on the internally equally angled limiting components 125. This enables the support seat 13 to adaptively adjust its position according to the diameter of the pot blank and accurately lift the bottom of the plate cut. After the cutting is completed, the rotating column 9 rotates as a whole, and the support seat 13 rotates synchronously to scrape off the slag and nodules on the bottom surface of the pot blank, stabilize the quality of the multi-layer composite plate cut section and reduce the subsequent grinding process.

[0036] As a further embodiment of the present invention, a buffer spring 128 is provided on the outer sleeve of the limiting rod 127. One end of the buffer spring 128 is fixedly connected to the fixed frame 14, and the other end of the buffer spring 128 is fixedly connected to the lifting member 121.

[0037] In practice, when the lifting component 121 slides up and down along the limiting rod 127 fixed to the fixed frame 14, the buffer spring 128 sleeved on the outside of the limiting rod 127 will be compressed or stretched synchronously with the displacement of the lifting component 121. The elastic buffer of the buffer spring 128 absorbs the rigid impact generated by the movement of the lifting component 121, reducing the impact damage to the multi-layer composite board during the adjustment of the support seat 13. At the same time, the vibration caused by the buffer pressure linkage transmission makes the radial adjustment action of the support seat 13 more stable, ensuring the stability of the bottom support of the board and avoiding defects such as indentation and local warping of the board.

[0038] As a further embodiment of the present invention, the fixed column 122 is provided with a movable threaded groove for the threaded rod 123, and the turntable 124 is provided with a movable guide groove for the limiting member 125.

[0039] In practice, when the lifting component 121 drives the fixed column 122 to move vertically, the threaded groove inside the fixed column 122 engages with the threaded rod 123, converting the linear displacement into the rotational motion of the threaded rod 123. The threaded rod 123 synchronously drives the turntable 124 to rotate. The turntable 124 drives the limiting component 125 to slide through its own guide groove, thereby driving the support seat 13 to synchronously adjust the spacing radially. This enables the support seat 13 and the upper roller 6 to synchronously adapt to pot blanks of different diameters, forming a stable support below the cut of the plate, reducing the problems of bottom slag and excessive taper of the cut caused by the plate hanging in the air.

[0040] As a further embodiment of the present invention, the turntable 124 is rotatably connected to the slide rail 126, the slide rail 126 is fixedly connected to the inner wall of the rotating column 9, and the slide rail 126 has a cavity that moves in conjunction with the support seat 13.

[0041] In practice, when the turntable 124 rotates, the limiting component 125 drives each support seat 13 to slide radially synchronously along the cavity of the slide rail 126, completing the adaptive adjustment of the position of the support seat 13, so that the support seat 13 is always aligned with the bottom of the pot blank cut to provide rigid support, reducing the bottom slag and cut taper defects caused by the plate being suspended. After the cutting is completed, the rotating column 9 drives the slide rail 126 and the support seat 13 to rotate as a whole, so that the cutting edge of the support seat 13 can be used to scrape off the molten slag and nodules on the bottom surface of the pot blank.

[0042] Working principle: When using this multi-layer metal pressing integrated stainless steel pot laser cutting machine, the non-appearance area of ​​the top surface of the composite plate is first held by a vacuum suction cup, and the whole plate is steadily lifted to the worktable at the top of the main body 1 of the equipment. The plate coordinates are calibrated by the mechanical edge positioning component or vision positioning system, so that the composite plate is accurately placed on the top surface of the support 13. Then, according to the total thickness of the composite plate and the material of each layer, the cutting process parameters are matched, and the corresponding laser power, cutting speed and pulse piercing frequency are set. At the same time, the height follow-up system of the moving seat 2 is calibrated to prepare for the subsequent cutting. When the moving seat 2 descends along the Z-axis to calibrate the cutting height, the cutting head 3 fixed on the moving seat 2 and the base 4 move towards the top surface of the composite plate synchronously. As the moving seat 2 continues to descend, the roller 6 at the bottom of the base 4 contacts the top surface of the composite plate first. As the moving seat 2 continues to descend, the moving rod 508, which is rotatably connected to the roller 6, slides upward along the inner cavity of the connecting rod 506, compressing the compression spring 507 between the connecting rod 506 and the moving rod 508 to store energy, ultimately forming a stable elastic preload. When the cutting head 3 cuts along the outline of the circular pot blank, the roller 6 always... Rolling and pressing along both sides of the cut, in conjunction with the reverse support of the lower support seat 13, forms a clamping constraint state between the upper and lower parts, maintaining the planar stability of the composite board cutting area throughout the process. The roller 6 is made of high-temperature resistant ceramic material and is a pure rolling contact, which will not scratch the food-grade smooth surface of the top stainless steel. The elasticity of the compression spring 507 can absorb the small vibrations during the cutting process, improve the flatness of the cut, reduce the burrs on the cross-section, and the rolling and pressing throughout the process can offset the warping of the board caused by the thermal stress of cutting, ensure the relative position of the laser focus is stable, and thus maintain the perpendicularity and dimensional accuracy of the cut. When changing to different diameter blanks for production, the electric push rod is activated, which drives the lifting frame 501 to move. This, in turn, causes the movable plate 502, which is fixed to the lifting frame 501, to slide on one side of the base 4. As the movable plate 502 moves, it simultaneously drives the slider 503, which is slidably connected to it, to move. When the slider 503 moves, it causes the guide rod 504, which is fixed on one side of it, to slide within the Z-shaped inclined groove and the straight groove opened in the guide plate 505. Under the constraint of vertical displacement, this is converted into radial horizontal displacement of the slider 503, enabling multiple groups of sliders 503 to simultaneously spread out and retract at equal distances. When the slider 503 moves horizontally while lifting, it simultaneously drives the bottom fixed... The connecting rod 506 moves to adjust the spacing between multiple rollers 6. After the multiple rollers 6 are spread out at equal intervals, they can form a uniform holding force along the circumference of the circular cut, avoiding insufficient local force caused by single-roller holding. This comprehensively suppresses the circumferential thermal deformation and interlayer peeling of the circular blank, ensuring the stability of the roundness tolerance of the pot blank. At the same time, the compression spring 507 between the connecting rod 506 and the moving rod 508 is further compressed, ensuring that the rollers 6 always press the composite plate with a constant pressure under different sizes. The spring compression changes synchronously with the spacing adjustment, ensuring that the holding force under different pot diameters is always in the optimal range. It will not lose the anti-warping effect due to too little pressure, nor will it cause plastic indentation of the plate due to too much pressure. When the lifting frame 501 moves, it synchronously drives the first sliding rod 7 fixed at its bottom end to slide within the first oil tank 8, causing the oil in the first oil tank 8 to be transported to the second oil tank 10 through the hose. This causes the second sliding rod 11, which is limited to sliding within the second oil tank 10, to move. The movement of the second sliding rod 11 drives the lifting component 121, which is fixed to it, to move synchronously. When the lifting component 121 moves, it slides outside the limiting rod 127, causing the buffer spring 128 set between the lifting component 121 and the fixed frame 14 to be compressed. The movement of the second sliding rod 11 also drives the fixed column 122 fixed at its bottom end to move synchronously. Since the fixed column 122 has a mating thread, The movable threaded groove of the rod 123 allows the fixed column 122 to move and drive the threaded rod 123 to rotate, which in turn drives the turntable 124 fixed at the bottom of the threaded rod 123 to rotate synchronously. The turntable 124 is provided with a guide groove that moves in conjunction with the limiting member 125, so that the rotation of the turntable 124 drives the support seat 13 fixed with the limiting member 125 to slide in the slide rail 126. Ultimately, the position of the support seat 13 is synchronously and adaptively adjusted with the diameter of the pot blank, always aligned with the bottom of the cut, ensuring that there is always rigid support below the cut, avoiding the focus shift, bottom slag and increased cut taper caused by the plate hanging and sagging, and stabilizing the cutting section quality of the multi-layer composite plate. After the cutting process is completed, the waste material on the outside of the cut loses the support of the support seat 13 and is suspended in the air. At the same time, the compression spring 507 releases its elastic potential energy, causing the moving rod 508 to extend downwards and apply a downward pushing force to the suspended waste material. This directly breaks the micro-connection adhesion points between the waste material and the pot blank, achieving automatic detachment and separation of the waste material. The automatic detachment of the waste material eliminates the need for manual removal of each piece, reducing manual operation steps. The micro-connection is separated from top to bottom by the spring pushing force, replacing the traditional method of manual bending and breaking, and avoiding interlayer tearing caused by bending and shearing forces. Cracks, burrs, and edge deformation are removed while preserving the original strength of the cut, reducing the risk of cracking in subsequent stretching processes. After the waste is removed, the drive motor is started to rotate the rotating column 9, which in turn drives the support base 13 to rotate synchronously in the circumferential direction. Through the relative movement between the hard cutting edge at the top of the support base 13 and the cut on the lower surface of the pot blank, the incompletely solidified slag and lumps at the cut are completely scraped off. The slag is scraped off in time before it has completely cooled and hardened, resulting in high scraping efficiency and thorough effect. At the same time, the flat bottom cut can eliminate stress concentration points and reduce the risk of cracking in subsequent forming.
