Description

Technical Field

[0001] The present invention belongs to the technical field related to metal plate cutting, and more specifically, relates to a plate cutting device for metal manufacturing. Background Art

[0002] As electronic equipment continues to upgrade towards miniaturization and high performance, the demand for various precision components in the field of mechanical manufacturing is becoming increasingly strong, which makes mechanical manufacturing companies face higher standards in terms of production efficiency and product quality control. As a basic material widely used in mechanical manufacturing, the accuracy and efficiency of the cutting process of sheet metal are directly related to the performance of the end product and production cost control. Taking the automobile manufacturing, engineering machinery and other industries as examples, the production of a large number of mechanical parts with complex structures and precise dimensions requires that sheet metal cutting must achieve high precision and high stability in order to adapt to subsequent precision processing and assembly processes. However, the existing sheet metal cutting technology for mechanical manufacturing has obvious shortcomings: When cutting plates, if the support structure of the cutting actuator is not stable enough, or if there are design flaws in the fixing method, the vibration generated during the cutting process will be transmitted to the plate, causing displacement. For thin plates, the inherent rigidity is insufficient, and even a small vibration or displacement can easily cause the plate to deform, resulting in problems such as warping and burrs on the cut surface. For irregularly shaped plates, due to the uneven distribution of the center of gravity, conventional support and fixing methods are difficult to ensure stability during cutting. The interference of vibration and displacement is more likely to induce problems such as deviation in cutting surface accuracy and edge defects. Such cutting defects will not only interfere with the subsequent splicing and assembly processes of the plate, resulting in loose connections and poor matching accuracy of components, but will also cause flaws in the appearance and performance of the end product, weakening the overall quality and market competitiveness of the product.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a plate cutting device for metal manufacturing, which is provided with a guide rail positioning group. The positioning guide rails use high-precision straightness and flatness to build a physical positioning reference. The rectangular groove and positioning limit rod in the middle of the rail serve as a sliding track for the deburring unit on the one hand, and on the other hand, with the help of mechanical limit constraints, effectively prevent the metal plate from warping and deformation during the positioning and processing stages, further improving the stability and accuracy of positioning; the negative pressure positioner uses an air pressure-driven suction cup in a non-contact adsorption mode, relying on a rectangular air cavity, a piston push rod, a bellows and other structures to achieve flexible fixation of the metal plate.

[0017] The present invention provides a plate cutting device for metal manufacturing, which is provided with a deburring unit. The deburring unit forms a sliding connection structure with the wedge-shaped guide rail of the positioning guide rail and the central positioning groove of the positioning limit rod through a sliding connection seat, which can realize real-time displacement adjustment along the edge of the metal plate. This design can accurately capture the position changes of the metal plate. Even if the metal plate produces a slight displacement during the cutting process, the position calibration can be completed quickly to ensure that the component and the edge of the metal plate remain in a tight fit, thereby providing a precise reference for the deburring process and effectively avoiding the problem of poor deburring effect caused by positioning deviation. In addition, the component and the cutting work head adopt a linkage design, which can perform deburring operations simultaneously with the cutting operation. The transmission roller group, side transmission teeth and center transmission teeth in the transmission roller group constitute a transmission system. This system can convert the moving kinetic energy of the metal plate into driving force, driving the cleaning brush assembly to rotate or move linearly, and can promptly remove burrs and debris generated during the cutting process. This design reduces the secondary processing links, significantly improves processing efficiency, and effectively shortens the production cycle.

[0018] The present invention provides a plate cutting device for metal manufacturing, which is provided with a soft brush and an exhaust hole. The soft brush and the exhaust hole form an efficient cleaning system: the soft brush is made of a flexible material that fits tightly to the surface of the metal plate, and through mechanical friction, it can effectively brush away burrs and debris generated during the slitting process. It is made of a low-hardness, high-flexibility material, can adapt to the undulations on the surface of the metal plate, and contact the plate with uniform and gentle pressure to avoid physical damage such as scratches and indentations to the plate. The exhaust hole simultaneously generates airflow, which can promptly absorb or blow away impurities loosened by the soft brush, preventing the impurities from attaching to the surface of the metal plate for the second time. In this way, a dual cleaning mode of "contact cleaning + airflow assistance" is formed to ensure that there are no visible or microscopic residual pollutants on the surface of the metal plate.

[0036] Preferably, refer to the attached Figure 15 The helical gear transmission group 47 includes a driven helical gear 73, and two groups of main helical gears 72 are meshed on the surface of the driven helical gear 73. The opposite surfaces of the two groups of main helical gears 72 are provided with a first tooth groove connecting block 74 and a second tooth groove connecting block 76. An intermediate tooth connecting block 75 is slidingly provided between the first tooth groove connecting block 74 and the second tooth groove connecting block 76. The intermediate tooth connecting block 75 rotates in coordination with the first tooth groove connecting block 74 and the second tooth groove connecting block 76. The distance between the first tooth groove connecting block 74 and the second tooth groove connecting block 76 and the intermediate tooth connecting block 75 is equal to the distance between the two isolation grooves of the limiting guide groove 49; the driven helical gear 73 drives the main helical gears 72 on both sides to rotate in the same direction through the bevel gear reversing structure to ensure synchronous transmission.

[0037] Preferably, refer to the attached Figure 1 A machining reference platform 13 is provided on the upper part of the machining main frame 11, and side guide rail grooves 14 are provided on both sides of the machining reference platform 13. A cutting actuator 12 is slidably provided in the side guide rail groove 14, and the two groups of roller moving groups 28 provided in the cutting actuator 12 slide in the side guide rail groove 14.

[0038] Specific use of the present invention: The power transmission system of this sheet metal cutting device for metal manufacturing features an ingenious design. When the auxiliary drive motor 24 is activated, the motor shaft drives the power take-off pulley 25 in synchronous rotation. Leveraging the efficiency of the belt drive, the power take-off pulley 25 quickly and stably transmits power to the large gear plate, causing it to rotate. A drive shaft 27 runs through the center of the large gear plate, with a set of roller moving assemblies 28 mounted on each end. Each roller moving assembly 28 forms an equilateral triangle, as clearly illustrated in the top view of Figure 4. This equilateral triangle layout, like a sturdy tripod, not only provides excellent structural stability but also provides excellent guidance for the cutting actuator 12 during movement, like a precise navigator. Within the roller moving assembly 28, the central rotating pulley is firmly connected to the drive shaft 27, while the auxiliary pulleys on either side are linked by a synchronous belt. When the triangular vertices of the three wheels precisely match the guide rails of the side guide grooves 14, just like the perfect fit between a key and a lock cylinder, the cutting actuator 12 can move smoothly in the vertical direction, achieving precise positioning and displacement in the vertical dimension, ensuring the accuracy of the cutting work in the vertical direction.

[0039] At the same time, the main drive motor 19 begins to rotate, driving the active drive wheel 21 via a pulley. The active drive wheel 21 rotates the driven roller assembly 22, which in turn circulates the flexible drive belt 23. The sliding roller 33 and the flexible drive belt 23 utilize a shaft-keyed structure, a fitting arrangement that resembles tightly meshed gears. When the flexible drive belt 23 moves, the sliding roller 33 rotates with it, driving the cutting head 17 to move laterally along the slide rail assembly of the U-shaped frame 31, achieving horizontal movement of the cutting head. This coordinated vertical and horizontal motion creates a precise and efficient two-dimensional motion system for cutting, allowing cutting operations to be performed flexibly in different dimensions.

[0040] During the crucial positioning step before cutting, the center of the negative pressure locator 36 of the workpiece locator 18 must be precisely aligned with the cutting line of the metal sheet. This step, like a sniper aiming at a target, is the foundation for subsequent precision cutting. Once the cutting head 17 is vertically positioned, the suction cup of the negative pressure locator 36 presses into contact with the surface of the metal sheet. At this point, the vacuum pump begins operating, supplying air to the bellows through a pipe. The one-way air inlet valve opens, and the powerful thrust generated by the gas pushes piston 68 toward the second transverse air guide 67. The movement of piston 68 is then transmitted through piston push rod 71, creating a negative pressure inside the suction cup. This, like an octopus's tentacles firmly grasping an object, securely holds the metal sheet in place, completing the initial positioning. This process effectively ensures the stability of the metal sheet during cutting, preventing deviations caused by shaking and ensuring precise cutting.

[0041] Let's take a closer look at the structure and operating principles of the first and second transverse air ducts 66 and 67. The upper portion of the first transverse air duct 66 forms a rectangular air chamber, within which a piston 68 is transversely mounted. This chamber is connected to the wall of the chamber by a bellows, which in turn communicates with the interior of the chamber. The lower portions of both the first and second transverse air ducts 66 and 67 are connected to suction cups. When gas enters the chamber, it acts as a force in the piston 68, pushing it forward. This creates negative pressure on the suction cup through the piston push rod 71, enabling suction. When the gas is exhausted, the piston 68 loses its thrust and returns to its initial position, unlocking the suction cup. The bellows play a crucial role in this process, expanding and contracting as the piston 68 moves, thereby driving the piston push rod 71 and ensuring smooth suction and unlocking. The first transverse air duct 66 and the second transverse air duct 67 are connected through the air hose 63 to form a smooth air flow path, ensuring that the gas can flow unimpeded between the two, so that the suction cup can normally perform the adsorption or unlocking function and ensure the stable operation of the positioning system.

[0042] As the cutting head 17 moves laterally, the deburring unit 40 moves along the positioning and limiting rod 37. During this process, the deburring unit 40 compresses the spring support tube 38, allowing compressed air to enter the first and second transverse air ducts 66 and 67 through the air hose 63. The pressure of the compressed air pushes the piston 68 to move sideways, lifting the suction cups off the metal sheet via the piston push rod 71. The deburring unit 40 and the cutting head 17 are linked by a PLC. This precise linkage, like the gears of a precision clock, ensures that the suction cups are released from the metal sheet 0.5 seconds before cutting, preventing them from obstructing the sheet's movement and ensuring smooth cutting.

[0043] After cutting is complete, the one-way return valve opens, allowing the gas in the suction cup to flow back into the tube. This reverse pressure pushes piston 68 back into its original position. The spring support tube 38, under the elastic action of the return spring, returns to its original position, driving the guide rail positioning assembly 39 toward the deburring unit 40, causing the negative pressure positioner 36 to eject. This series of significant mechanical changes, like a signal light, intuitively indicates that the cutting operation has been successfully completed, providing a clear indication for subsequent operations.

[0044] During the cleaning and polishing process, the cleaning brush assembly 54 plays a key role. The bottom of the U-shaped groove of the cleaning brush assembly 54 features a nitrile rubber pad with a serrated surface, which generates a 5N clamping force through line contact. This clamping force acts like a powerful pair of hands, firmly gripping the metal sheet and preventing it from slipping during the cleaning and polishing process, ensuring stability during the cleaning and polishing process. The clamping and cutting compound unit 42 includes the cleaning brush assembly 54. The bottom of the U-shaped groove of the cleaning brush assembly 54 features an elastic rubber pad with a serrated surface, specifically designed to accommodate the flat surface of the metal sheet. A keyed connection between the power output shaft 44 and the drive shaft 62 transmits torque, ensuring stable power transmission and driving the cleaning brush assembly 54 effectively.

[0045] The drive roller assembly 59 plays a crucial role in the cleaning and polishing mechanism. The outer ends of the drive roller assembly 59 are fixedly connected to the side drive teeth 60. A central drive tooth 61 is positioned between the two sets of side drive teeth 60 via a gear mechanism. The outer ends of the central drive teeth 61 are fixedly connected to a transmission connecting shaft 62. In actual operation, the drive roller assembly 59 uses an idler gear to change its rotational direction, causing the side drive teeth 60 on either side to rotate in opposite directions. This effectively prevents interference between the central drive teeth 61 during transmission and ensures stable operation of the cleaning and polishing mechanism. It is important to note that the drive roller assembly 59 does not directly contact the metal sheet; instead, it drives the sheet through other components. When the drive roller assembly 59 rotates, the idler gear changes its rotational direction, causing the side drive teeth 60 on either side to rotate in opposite directions. This allows the central drive teeth 61 to rotate normally without interference, ensuring smooth power transmission throughout the cleaning and polishing mechanism.

[0046] The positioning shaft 46 features a bidirectional trapezoidal thread design with two sections: one left-handed and the other right-handed. As the positioning shaft 46 rotates, the displacement drive mechanism 50 moves along the thread, much like a nut on a screw. When the shaft reaches the intersection of the two sections, a reversing block at the end triggers the elastic stopper 52. The top ball of the elastic stopper 52 shifts from the left to the right slot of the limiting guide slot 49, thereby changing the direction of movement of the displacement drive mechanism 50 and achieving reciprocating motion. The cleaning assembly includes the positioning shaft 46, which features a bidirectional trapezoidal thread and a reversing block at its end. When the displacement drive mechanism 50 contacts the reversing block, the top ball of the elastic stopper 52 shifts the position of the limiting guide slot 49, achieving reciprocating motion. This allows the cleaning brush assembly 54 to reciprocate and polish the cut surface, improving cleaning and polishing efficiency.

[0047] Pressure sensors at both ends of the threaded spring tube 69 monitor pressure changes in real time. When the pressure reaches 0.8 MPa, the pressure relief valve is triggered, reducing the air pressure to 0.3 MPa. The displacement drive mechanism 50 then moves in the opposite direction under the action of the spring force. This pressure control mechanism, like a smart housekeeper, not only ensures the safety of the cleaning and polishing process but also ensures the stability of the mechanism's operation. At the same time, pressure sensors are installed at both ends of the threaded spring tube 69. When the displacement drive mechanism 50 approaches the intersection of the threads, the pressure sensors trigger airway pressure relief to prevent jamming. A soft brush is installed in the U-shaped slot of the sliding connector 55 and is connected to the threaded spring tube 69 through an exhaust hole to achieve air jet cleaning. When the cleaning brush assembly 54 is in operation, air jet cleaning is performed simultaneously, further improving the cleaning effect.

[0048] Furthermore, the design of the helical gear transmission assembly 47 is also exceptionally sophisticated. It comprises a driven helical gear 73 and two main helical gears 72. The driven helical gear 73 drives the two main helical gears 72 in the same direction through a bevel gear reversing mechanism. The distances between the first and second tooth groove connecting blocks 74, 76, and the intermediate tooth connecting block 75 precisely match the limiting guide slots 49, ensuring synchronized transmission. This precise transmission coordination allows the cleaning brush assembly 54 to simultaneously polish the cut surface as it reciprocates. Simultaneously, air is ejected from the air cleaning holes 70 to promptly remove burrs generated during the cutting process, ensuring that the cut metal sheet meets process requirements and safeguarding the quality of the cut metal sheet in multiple ways.
