Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting machines, and specifically relates to a follow-up limit type metal cutting machine. Background Technique

[0002] A metal laser cutting machine, as a high-tech device integrating laser technology, precision machinery technology, and numerical control technology, uses a high-energy laser beam to irradiate the surface of a metal workpiece. The energy released by the laser beam causes the metal to quickly melt and vaporize, and a high-speed air flow is used to blow away the molten material, thereby achieving high-precision and high-efficiency cutting.

[0003] For example, a Chinese patent with the publication number: CN219310372U, the patent name: A metal plate laser cutting device, and the publication date: July 7, 2023, includes an operating table board. The back of the top of the operating table board is fixedly installed with a back board, and the left side of the back of the back board is fixedly installed with a filter box. Through the setting of the driving sleeve, it can slide left and right on the top of the driving track, and when sliding, it will drive the laser cutting head to adjust its position. At the same time, by moving the driving sliding sleeve back and forth on the surface of the sliding rod, the laser cutting head can be driven to adjust its position. And when the laser cutting head is performing laser cutting, through the setting of the smoke suction board, the smoke generated during cutting can be directly sucked out. The suction force is provided by the suction fan body, and the sucked smoke can directly enter the filter box. Among the above-mentioned existing technologies, the following technical problems exist:

[0004] When the existing cutting machine performs laser cutting on metal, it is not convenient to clean the debris remaining during the laser cutting process. The working table surface of the cutting machine is usually flat. When the debris accumulates, it is easy to affect the flatness of the placement of metal parts during subsequent metal cutting. When the placement angle of the metal part is deviated, it will also greatly affect the precision of laser cutting subsequently.

[0005] Therefore, we propose a follow-up limit type metal cutting machine to facilitate solving the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a follow-up limit type metal cutting machine to solve the problems raised in the above background technique, that is, when the existing cutting machine on the current market performs laser cutting on metal, it is not convenient to clean the debris remaining during the laser cutting process. The working table surface of the cutting machine is usually flat. When the debris accumulates, it is easy to affect the flatness of the placement of metal parts during subsequent metal cutting. When the placement angle of the metal part is deviated, it will also greatly affect the precision of laser cutting subsequently.

[0007] To achieve the above object, the present invention provides the following technical solution: A follow-up limit type metal cutting machine, including a support bracket and a servo motor installed on the upper side of the support bracket. The output end of the servo motor is installed with an adjustment screw rod for controlling the movement of the support substrate, and a laser cutting head is installed on the side of the support substrate. The lower end of the support substrate penetrates through a positioning cross bar fixed on the support bracket. A clamping component for fixing the metal part is arranged on the side of the support bracket, and a lifting substrate is arranged between the two clamping components on both sides. A clamping vertical rod is connected to the lifting substrate through an auxiliary spring and penetrates through it, and multiple clamping vertical rods form a support platform for the metal parts to be cut in a dot matrix form.

[0008] Preferably, the middle of the support substrate is threadedly connected to the adjustment screw rod, and the lower end of the support substrate can slide on the positioning cross bar. By rotating the adjustment screw rod, the support substrate connected by threads can drive the laser cutting head to move horizontally, thereby automatically cutting the metal part by using the movement of the laser cutting head.

[0009] By adopting the above technical solution, by rotating the adjustment screw rod, the support substrate connected by threads can move on the positioning cross bar, thus preventing the support substrate from rotating synchronously with the adjustment screw rod.

[0010] Preferably, the clamping components are symmetrically arranged about the longitudinal central axis of the support bracket, and the clamping components include a power cylinder fixed on the side of the support bracket and a side clamping baffle installed at the telescopic end of the power cylinder. An elastic rubber pad is arranged at the end of the side clamping baffle for clamping the metal part to be cut.

[0011] By adopting the above technical solution, by opening the power cylinder, the side clamping baffle at the end can clamp the metal part, and at the same time, the elastic rubber pad on the side clamping baffle can play a role in clamping and buffering the metal part.

[0012] Preferably, the upper surface of the lifting substrate is set as an inclined surface, and a plurality of through clamping vertical rods are evenly distributed on the lifting substrate, and the upper end of the clamping vertical rod is set as an arc structure. Through each independent clamping vertical rod, it is convenient to support metal parts with different bottom shapes. Each clamping vertical rod can move and adjust according to the corresponding support position, thereby improving the support effect on special-shaped metal parts, and multiple clamping vertical rods form a dot matrix support platform, thereby preventing debris from accumulating on the clamping vertical rods with an arc-shaped top surface.

[0013] By adopting the above technical solution, through the setting of the lifting substrate, the debris staying on it can be guided, and at the same time, the arc-shaped structure at the upper end of the clamping cross bar can prevent the debris from staying.

[0014] Preferably, the clamping vertical rod forms an elastic telescopic structure through an auxiliary spring and a lifting substrate, and the vertices of each clamping vertical rod on the lifting substrate are located on the same plane.

[0015] By adopting the above technical solution, through the movement of each independent clamping vertical rod on the lifting substrate, it can move and adjust following metal parts with different ground shapes.

[0016] Preferably, an impact frame is arranged at the lower end of the clamping vertical rod, and a plugging rod is installed through the impact frame. The impact frame is connected to the plugging rod through a return spring, and driving magnets are inlaid in the middle of the upper end of the impact frame and the middle of the lower end of the clamping vertical rod. After the clamping vertical rod moves downward, the driving magnet on it can be close to the clamping magnet on the impact frame, and the impact frame can be moved upward by the magnetic force, and the lifting substrate can be impacted. By impacting the lifting substrate, it is convenient for the debris on the lifting substrate to slide down along the inclined plane.

[0017] By adopting the above technical solution, through the setting of the return spring, the impact frame that moves on the plugging rod can be reset and rebound.

[0018] Preferably, the opposite sides of the driving magnets on the impact frame and the clamping vertical rod have opposite magnetic polarities, and the impact frame and the plugging rod are in sliding connection.

[0019] By adopting the above technical solution, after the clamping vertical rod moves downward, the impact frame can be moved upward by using two driving magnets with opposite magnetic polarities, so as to impact the lifting substrate.

[0020] Preferably, a piston guide rod is fixed on the side of the side clamping baffle away from the center of the lifting substrate, and the piston guide rod penetrates through the support bracket and is inserted into the air storage column. The air storage column is connected to the storage block through a connecting pipe, and the storage block is fixed at the top of the lifting substrate, and an air outlet through hole is arranged on one side of the storage block facing the bottom of the lifting substrate.

[0021] By adopting the above technical solution, through the movement of the side clamping baffle, the piston guide rod on the side can be driven to move synchronously inside the air storage column.

[0022] Preferably, a sealing ring is circumferentially fixed at one end of the piston guide rod located inside the air storage column, and the piston guide rod can slide inside the air storage column, and the air storage column is internally connected to the inside of the storage block through a connecting pipe.

[0023] By adopting the above technical solution, through the sealing ring at the end of the piston guide rod, the sealing performance of the piston guide rod when moving inside the air storage column can be ensured, and the phenomenon of air leakage can be prevented.

[0024] Preferably, the inside of the storage block is arranged as a hollow structure, and a plurality of air outlet through holes are evenly distributed on the side of the storage block. After the side clamping baffle moves towards the center direction of the lifting substrate, the storage block and the air outlet through holes can be used to suck the external air flow. After the cutting is completed, the piston guide rod moves and resets inside the air storage column, so that the air flow inside the air storage column is sprayed out along the inclined surface of the lifting substrate through the connecting pipe, the storage block and the air outlet through holes, thereby facilitating the blowing off of the debris staying on the inclined surface of the lifting substrate and facilitating subsequent centralized collection.

[0025] By adopting the above technical solution, when the air flow enters the inside of the storage block, the air flow inside the storage block can be discharged outwards through the air outlet through holes on the side, so as to blow off the debris staying on the lifting substrate from top to bottom.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The follow-up limit type metal cutting machine can conveniently clean the debris accumulated during the laser cutting of metal parts, avoiding the influence of the accumulation of debris on the flatness of the subsequent placement of metal parts;

[0029] 3. An impact frame is provided. After the clamping vertical rod moves downward, the driving magnetic block on it and the clamping magnetic block on the impact can approach each other.

[0030] 4. An air outlet through hole is provided. After the side clamping baffle moves towards the center direction of the lifting substrate, the storage block and the air outlet through hole can be used to suck the external air flow.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1: Please refer to Figures 1 - 9, when the existing cutting machine performs laser cutting on metal, it is not convenient to clean the debris remaining during the laser cutting process. The working surface of the cutting machine is usually flat. When debris accumulates, it is likely to affect the flatness of the placement of metal parts during subsequent metal cutting. When there is a deviation in the placement angle of the metal parts, it will also greatly affect the accuracy of laser cutting in the future. To solve this technical problem, the following technical content is disclosed in this embodiment. A follow-up limit type metal cutting machine includes a support bracket 1 and a servo motor 2 installed on the side of the upper end of the support bracket 1. The output end of the servo motor 2 is equipped with an adjustment screw rod 3 for controlling the movement of the support substrate 4, and a laser cutting head 5 is installed on the side of the support substrate 4. A positioning cross bar 6 fixed to the support bracket 1 penetrates through the lower end of the support substrate 4. A clamping component for fixing the metal part is arranged on the side of the support bracket 1, and a lifting substrate 9 is arranged between the two clamping components. A through clamping vertical rod 10 is connected to the lifting substrate 9 through an auxiliary spring 11, and a plurality of clamping vertical rods 10 form a support platform for the dot matrix type metal parts to be cut. The middle part of the support substrate 4 is threadedly connected to the adjustment screw rod 3, and the lower end of the support substrate 4 can slide on the positioning cross bar 6. The clamping components are symmetrically arranged with respect to the longitudinal central axis of the support bracket 1, and the clamping components include a power cylinder 7 fixed to the side of the support bracket 1 and a side clamping baffle 8 installed at the telescopic end of the power cylinder 7. An elastic rubber pad is arranged at one end of the side clamping baffle 8 for clamping the metal part to be cut. The upper surface of the lifting substrate 9 is set as an inclined surface, and a plurality of through clamping vertical rods 10 are evenly distributed on the lifting substrate 9. The upper end of the clamping vertical rod 10 is set as an arc structure. The clamping vertical rod 10 and the lifting substrate 9 form an elastic telescopic structure through the auxiliary spring 11, and the vertices of each clamping vertical rod 10 on the lifting substrate 9 are located on the same plane.

[0043] When it is necessary to cut a metal part, place the metal part on the clamping vertical rod 10 on the lifting substrate 9. Since there are multiple clamping vertical rods 10 evenly distributed on the lifting substrate 9, each clamping vertical rod 10 can be moved and adjusted according to the shape of the bottom surface of the metal part. After the metal part is placed stably, turn on the power cylinder 7. After the power cylinder 7 is turned on, it can make the side clamping baffle 8 move towards the center direction of the lifting substrate 9. The movement of the side clamping baffle 8 can limit the metal part to be cut, so as to ensure the stability of the metal part during cutting. Place the debris collection container at the lowest end of the inclined surface of the lifting substrate 9, and then use the laser emitted by the laser cutting head 5 to cut the limited metal part. During the cutting process, the servo motor 2 can be turned on. After the servo motor 2 is turned on, it can make the adjusting screw rod 3 drive the supporting substrate 4 to move, so that the laser cutting head 5 moves synchronously with the movement of the supporting substrate 4, thereby improving the cutting effect of the metal part. During the cutting process, the remaining debris falls on the lifting substrate 9, and the inclined surface of the lifting substrate 9 can guide the debris to the debris collection container. The upper end of the clamping vertical rod 10 is set to be arc-shaped, and the arc surface setting can prevent debris from staying on it, thus preventing the subsequent placement flatness of the metal part from being affected by the accumulation of debris.

[0044] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. The following technical content is disclosed in this embodiment. An impact frame 12 is provided at the lower end of the clamping vertical rod 10, and a plugging rod 13 is installed through the impact frame 12. The impact frame 12 is connected to the plugging rod 13 through a return spring 14. A driving magnet 15 is embedded in the middle of the upper end of the impact frame 12 and the middle of the lower end of the clamping vertical rod 10. The opposite sides of the driving magnets 15 on the impact frame 12 and the clamping vertical rod 10 are magnetically opposite, and the impact frame 12 and the plugging rod 13 are slidably connected. A piston guide rod 16 is fixed to the side of the side clamping baffle 8 away from the center of the lifting substrate 9, and the piston guide rod 16 passes through the support bracket 1 and is inserted into the air storage column 17. The air storage column 17 is connected to the storage block 19 through a communication pipe 18, and the storage block 19 is fixed to the top of the lifting substrate 9. An air outlet through hole 20 is provided on one side of the storage block 19 facing the lowest end of the lifting substrate 9. A sealing ring is circumferentially fixed at one end of the piston guide rod 16 located inside the air storage column 17, and the piston guide rod 16 can slide inside the air storage column 17. The air storage column 17 is internally connected to the inside of the storage block 19 through the communication pipe 18. The inside of the storage block 19 is a hollow structure, and a plurality of air outlet through holes 20 are evenly distributed on the side of the storage block 19.

[0045] After the clamping vertical rod 10 moves downward under the pressure of the metal part, the movement of the clamping vertical rod 10 can make the driving magnets 15 at the lower end and the driving magnets 15 on the impact frame 12 approach each other. At this time, by the action of the magnetic attraction force between the two driving magnets 15, the impact frame 12 can move along the upper part of the insertion rod 13. By using the movement of the impact frame 12, the lifting substrate 9 can be impacted, thereby reducing the adhesion of debris on the lifting substrate 9 and facilitating the shaking off of the debris on the lifting substrate 9 along the inclined plane. Since the multiple clamping vertical rods 10 are independently arranged, each time the metal part is supported, one or more impact frames 12 below the clamping vertical rods 10 will impact the lifting substrate 9 under the action of magnetic force. At the same time, after the side clamping baffle 8 moves towards the center direction of the lifting substrate 9, the movement of the side clamping baffle 8 can make the piston guide rod 16 move synchronously. After the piston guide rod 16 moves inside the air storage column 17, it can extract the external air flow through the connecting pipe 18, the storage block 19 and the air outlet through hole 20. After the metal part is cut, when the side clamping baffle 8 returns to its original position, it can drive the piston guide rod 16 to return synchronously. After the piston guide rod 16 moves back, it can squeeze the air flow inside the air storage column 17 into the storage block 19 through the connecting pipe 18. The air flow inside the storage block 19 is sprayed downward along the inclined plane of the lifting substrate 9 from top to bottom through the air outlet through hole 20 on the side. By using the sprayed air flow, the debris staying on the inclined plane of the lifting substrate 9 can be blown downward into a unified collection container.

[0046] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
