Description

Technical Field

[0001] This invention relates to the technical field of feeding devices for perforating machines, specifically a fully automatic feeding device for perforating machines. Background Technology

[0002] Against the backdrop of the booming development of modern manufacturing, perforating machines, as a key piece of equipment, are widely used in many fields. In the metal processing industry, perforating machines are used to drill holes in various metal sheets and pipes, laying the foundation for subsequent assembly and connection processes. In the electronics manufacturing field, perforating machines can process fine holes in tiny electronic components to meet the high-precision and miniaturized production needs of electronic devices. In the aerospace industry, perforating machines play an important role in manufacturing parts with special performance requirements, such as precisely drilling holes in key components like aero-engine blades to achieve specific cooling, airflow control, and other functions. With the upgrading of industries and the continuous improvement of product refinement, higher requirements are also placed on the feeding devices of perforating machines. Efficient, accurate, and stable feeding is a key link to ensure that perforating machines perform at their best, improve production efficiency, and guarantee product quality.

[0003] The feeding device of a piercing machine mainly consists of a drive mechanism, a conveying mechanism, a positioning mechanism, and a control system. The drive mechanism typically uses a motor or cylinder to provide stable driving force for the feeding process. The conveying mechanism includes components such as a conveyor belt, guide rails, and rollers, used to carry and transport the material to be processed. The positioning mechanism uses sensors, clamps, and other components to accurately position the material. The control system coordinates the operation of each part, precisely controlling the feeding speed, distance, and positioning accuracy according to set parameters. Its working principle is as follows: the drive mechanism starts under the command of the control system, driving the conveying mechanism to transport the material to be processed to the designated position. During the process, the positioning mechanism monitors and adjusts the material position in real time to ensure that the material accurately reaches the piercing station. When the material is in place, the control system sends a signal to stop the drive mechanism, waiting for the piercing machine to complete processing. Then, the above process is repeated to achieve continuous automated feeding.

[0004] In existing technologies, the feeding device of a perforating machine lacks an effective linkage cleaning mechanism for the debris generated during the perforation process. If manual cleaning is not timely, the accumulation of debris will not only affect the accuracy of the board feeding, but will also enter the equipment and cause wear on the mechanical structure of the perforating machine, thereby affecting the operational stability and service life of the equipment. At the same time, frequent manual intervention to clean debris also interrupts the perforation process and reduces the overall perforation efficiency. Therefore, a fully automatic feeding device for a perforating machine is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fully automatic feeding device for a perforating machine, which solves the problem of the lack of a self-cleaning structure in the feeding device.

[0009] Preferably, the housing has a sliding groove inside, an electric guide is fixedly connected to the top of the housing, a perforated component is slidably connected inside the electric guide, and a plate is provided at the top of the fixed plate.

[0010] Preferably, the conveying mechanism includes a guide rail, the bottom end of which is fixedly connected to the top end of the housing, a sliding plate is slidably connected to the outside of the guide rail, a pneumatic clamp is fixedly connected to the top end of the sliding plate, a protective shell is fixedly connected to the top end of the housing, a drive assembly is provided inside the housing, and a connecting rod is fixedly connected to the bottom end of the sliding plate.

[0011] Preferably, the drive assembly includes a motor, the motor is externally fixedly connected to the inside of the housing, the drive end of the motor is fixedly connected to a threaded rod, and the external thread of the threaded rod is threadedly connected to the bottom end of the sliding plate.

[0012] Preferably, the housing has a sliding groove inside, and the bottom end of the sliding plate is slidably connected inside the sliding groove.

[0013] Preferably, the protective mechanism includes a fixed column, the bottom end of which is fixedly connected to the top end of the push rod, a transmission rod is rotatably connected to the outside of the fixed column, an arc-shaped plate is rotatably connected to the outside of the transmission rod, and a positioning column is fixedly connected to the bottom end of the arc-shaped plate.

[0014] Preferably, the guiding mechanism includes two positioning posts, which are respectively fixedly connected to the two ends of the housing. A limiting plate is fixedly connected to the outside of each positioning post. A guide block is rotatably connected to the outside of each positioning post. A fixed box is fixedly connected to the outside of the guide block. A moving block is slidably connected inside the fixed box. A guide wheel is rotatably connected to the top of the moving block. A telescopic post is fixedly connected to the outside of the moving block. A spring is sleeved on the outside of the telescopic post.

[0015] Preferably, one end of the telescopic column away from the moving block is fixedly connected to the inside of the fixed box, one end of the spring is fixedly connected to the inside of the fixed box, and the other end of the spring is fixedly connected to the end of the moving block near the telescopic column.

[0016] Preferably, the bottom end of the guide wheel is slidably connected to the inside of the fixed box, and the bottom end of the second positioning post is rotatably connected to the top end of the fixed plate.

[0017] This invention provides a fully automatic feeding device for a punching machine. It has the following advantages:

[0018] 1. This invention achieves automated and intelligent operation in automatic feeding of sheet metal and cleaning of drilling debris. After the sheet metal is placed in place, the motor drives the threaded rod to rotate, which moves the sliding plate. The pneumatic clamp then clamps the sheet metal and completes automatic feeding. When drilling is required, the cylinder pushes the push rod to clamp the sheet metal, while simultaneously moving the permanent magnet to fit against the guide plate. During the drilling process, the generated debris is attracted by the permanent magnet and falls onto the guide plate. After drilling is completed, the cylinder moves in the opposite direction to reset the permanent magnet, and the debris automatically falls into the collection box. The entire process does not require manual cleaning of debris. The automated feeding and debris collection mechanism not only reduces manual operation and labor intensity, but also effectively avoids the problem of debris accumulation caused by untimely manual cleaning, significantly improving drilling efficiency and equipment operation stability.

[0019] 2. In the sheet material feeding stage of this invention, the operator places the sheet material on the top of the sliding plate. After the sheet material contacts the guide block, the guide block rotates to guide and support it. At the same time, the sheet material squeezes the guide wheel, causing the moving block to slide and compress the spring in the fixed box. The spring generates a reverse elastic force that pushes the guide wheel, continuously applying force to the sheet material. This ensures that the sheet material remains centered during the sliding process, effectively preventing deviation. This adaptive adjustment process requires no manual intervention, can adapt to sheets of different sizes, greatly improves the accuracy and efficiency of feeding, reduces perforation errors caused by sheet material position deviation, lays a good foundation for subsequent perforation operations, and ensures a smooth and efficient perforation process.

[0020] 3. In terms of perforation protection and iron filings collection, this invention, through the movement of the push rod, drives the fixed column, transmission rod, and other components to rotate the arc-shaped plate. Supported by the positioning column, the arc-shaped plate rotates around a specific trajectory to form a protective barrier, effectively blocking iron filings from flying during the perforation process, protecting the safety of operators and maintaining a clean working environment. At the same time, the rotation of the arc-shaped plate can also guide the iron filings to gather in a specific area. Combined with the permanent magnet and guide plate of the cleaning mechanism, the iron filings are easier to collect and clean. This integrated design of protection and collection not only avoids the safety hazards and environmental pollution caused by flying iron filings, but also simplifies the subsequent cleaning process, improves cleaning efficiency, and ensures that the perforation operation is carried out safely, orderly, and efficiently.

[0031] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 This invention provides a fully automatic perforation machine feeding device, including a housing 1. The housing 1 is cast from a high-strength alloy material, possessing good rigidity and stability, and can withstand various forces during equipment operation, providing a solid foundation for the stable operation of internal mechanisms. A conveying mechanism 2 is provided at the top of the housing 1, which undertakes the core task of automatically conveying the sheet metal 8, and can accurately and efficiently deliver the sheet metal 8 to the perforation station. A fixing plate 3 is fixedly connected to the top of the housing 1. A cleaning mechanism 4 is provided inside the housing 1, which can automatically collect the debris generated during perforation, reducing the amount of manual cleaning work.

[0032] The cleaning mechanism 4 includes a second connecting rod 43, which is made of high-strength steel and has good toughness and strength. Its exterior can slide smoothly inside the housing 1 to ensure the reliability of the movement. A permanent magnet 44 is fixedly connected to the rear end of the second connecting rod 43. The permanent magnet 44 can generate a strong magnetic force to attract iron filings generated during perforation. A guide plate 45 is fixedly connected inside the housing 1. The inclined design of the guide plate 45 facilitates the smooth sliding of iron filings into the collection box 46. The collection box 46 is slidably connected inside the housing 1.

[0033] The transmission assembly 41 includes a cylinder 411, which has the characteristics of fast response speed and stable thrust. Its bottom end is fixedly connected to the top of the fixed plate 3 to ensure stable installation. The drive end of the cylinder 411 is fixedly connected to a push rod 412, which can accurately clamp and move the plate 8. The interior of the housing 1 is provided with a sliding groove 42, which provides guidance for the sliding of components such as the connecting rod 43. The top of the housing 1 is fixedly connected to an electric guide 9, and a perforating component 7 is slidably connected inside the electric guide 9. The electric guide 9 can accurately control the movement of the perforating component 7 to achieve precise perforation. The perforating component 7 is the key execution component for perforating the plate 8. The top of the fixed plate 3 is provided with a plate 8, which is the object to be processed.

[0034] Please see the appendix Figure 1 To be continued Figure 3 The conveying mechanism 2 includes a guide rail 25, which is manufactured with high-precision machining technology, has a smooth surface and high straightness. Its bottom end is fixedly connected to the top of the housing 1 by high-strength bolts to ensure a firm installation. A sliding plate 23 is slidably connected to the outside of the guide rail 25. The sliding plate 23 can slide smoothly on the guide rail 25 to ensure the accuracy of feeding. A pneumatic clamp 24 is fixedly connected to the top of the sliding plate 23. The pneumatic clamp 24 has the advantages of large clamping force and fast action, and can quickly and firmly clamp the plate 8. A protective shell 26 is fixedly connected to the top of the housing 1. The protective shell 26 can protect the internal components of the conveying mechanism 2 from dust, debris and other damage. A drive assembly 21 is set inside the housing 1. The drive assembly 21 provides power to the conveying mechanism 2. A connecting rod 27 is fixedly connected to the bottom of the sliding plate 23. The connecting rod 27 is used to connect the two guide rails 25 to achieve linkage.

[0035] The drive assembly 21 includes a motor 211, which is a high-torque, low-noise model. It is externally fixedly connected inside the housing 1 and operates stably and reliably. The drive end of the motor 211 is fixedly connected to a threaded rod 212, which is threadedly engaged with the sliding plate 23 to convert the rotational motion of the motor 211 into the linear motion of the sliding plate 23. A sliding groove 22 is provided inside the housing 1 to guide and support the sliding of the sliding plate 23. The bottom end of the sliding plate 23 is slidably connected inside the sliding groove 22 to ensure that the sliding plate 23 moves smoothly.

[0036] Please see the appendix Figure 1 Appendix Figure 6 and attached Figure 8The protective mechanism 6 includes a fixed column 61, which is firmly fixed to the top of the push rod 412 by welding to ensure connection strength. A transmission rod 62 is rotatably connected to the outside of the fixed column 61. The transmission rod 62 can rotate flexibly on the fixed column 61 to realize the transmission of force. An arc plate 63 is rotatably connected to the outside of the transmission rod 62. The arc plate 63 can rotate under the drive of the transmission rod 62 to block iron filings. A positioning post 64 is fixedly connected to the bottom end of the arc plate 63. The positioning post 64 provides support and positioning for the rotation of the arc plate 63. The bottom end of the positioning post 64 is rotatably connected to the top of the fixed plate 3 to ensure smooth rotation of the arc plate 63.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 7 The guiding mechanism 5 includes two positioning posts 51, which are fixed to both ends of the housing 1 by pre-embedded bolts, providing good stability. A limiting plate 52 is fixedly connected to the outside of the positioning posts 51. The limiting plate 52 is used to limit the rotation angle of the guide block 53 to ensure the accuracy of the guidance. A guide block 53 is rotatably connected to the outside of the positioning posts 51. The guide block 53 can rotate flexibly on the positioning posts 51 to guide the plate 8. A fixing box 54 is fixedly connected to the outside of the guide block 53. The fixing box 54 provides installation space and protection for the internal components. A moving block 55 is slidably connected inside the fixing box 54. The moving block 55 can slide smoothly inside the fixing box 54. A guide wheel 58 is rotatably connected to the top of the moving block 55. The guide wheel 58 has a smooth surface, which can reduce friction with the plate 8.

[0038] The movable block 55 is externally fixedly connected to a telescopic column 56, which can extend and retract when subjected to force to adapt to different thicknesses of sheet metal 8. A spring 57 is sleeved on the outside of the telescopic column 56, which provides elastic support for the guide wheel 58. The end of the telescopic column 56 away from the movable block 55 is fixedly connected to the inside of the fixed box 54 to ensure stable movement of the telescopic column 56. One end of the spring 57 is fixedly connected to the inside of the fixed box 54, and the other end of the spring 57 is fixedly connected to the end of the movable block 55 close to the telescopic column 56. The elastic force of the spring 57 enables the guide wheel 58 to adaptively adjust to the sheet metal 8. The bottom end of the guide wheel 58 is slidably connected to the inside of the fixed box 54 to ensure smooth movement of the guide wheel 58.

[0039] Working principle: When performing the perforation operation on the sheet metal 8, the operator places the sheet metal 8 on the top of the sliding plate 23 and starts the feeding process. During placement, the bottom of the sheet metal 8 first contacts the top of the guide block 53. The guide block 53 rotates rapidly outside the positioning post 51. With its flexible rotation characteristics, it immediately and accurately guides the sheet metal 8 and provides stable support, ensuring that the initial placement direction of the sheet metal 8 is accurate and avoiding difficulties in subsequent feeding due to misalignment. Then, as the sheet metal 8 slides on the sliding plate 23, its side contacts the outside of the guide wheel 58. After the guide wheel 58 is squeezed, it pushes the moving block 55 in the fixed box. The internal sliding of 54 compresses the spring 57, which generates a continuous reverse elastic force, pushing the moving block 55 to slide in the opposite direction. This ensures that the guide wheel 58 always maintains a pushing force on the plate 8. In this adaptive adjustment process, the guide wheel 58 adjusts its position and pushing force in real time according to the sliding of the plate 8. Even if there are differences in the size of the plate 8 or slight deviations in its placement, the dynamic adjustment of the guide wheel 58 can ensure that the plate 8 slides smoothly along the preset path on the sliding plate 23, ensuring its accurate position during the feeding process, preventing deviation, effectively improving the feeding efficiency of the plate 8, and laying a good foundation for subsequent perforation operations.

[0040] After the sheet material 8 is placed on top of the sliding plate 23, the motor 211 is started. The motor 211 drives the threaded rod 212 to rotate, thereby moving the sliding plate 23. The sliding plate 23 is connected to another sliding plate 23 via a connecting rod 27. The movement of the sliding plate 23 causes two pneumatic clamps 24 to hold the sheet material 8 and move it, thus achieving automatic feeding. When drilling is required, the cylinder 411 is started, causing the push rod 412 to clamp the outside of the sheet material 8. During the movement of the push rod 412, it will move through the connecting rod 27. Connecting rod 43 moves permanent magnet 44, causing its outer surface to adhere to the outer surface of guide plate 45. At this time, piercing component 7 is activated to pierce. The debris generated during piercing is attracted by permanent magnet 44 and falls to the top of guide plate 45. After piercing is completed, cylinder 411 is activated in reverse, causing connecting rod 43 to move permanent magnet 44 back to its original position. The debris at the top of guide plate 45 then falls into collection box 46 for collection, reducing manual cleaning operations and improving the efficiency and stability of piercing.

[0041] When the push rod 412 begins to move under the drive of the cylinder 411, the fixed column 61, which is firmly connected to the top of the push rod 412, moves synchronously. The movement of the fixed column 61 drives the transmission rod 62 to rotate. The transmission rod 62, with its flexible rotating connection structure, accurately transmits the force to the arc plate 63, pushing the arc plate 63 to rotate around the positioning column 64 as a fulcrum. As the arc plate 63 rotates, the two arc plates 63 gradually form a protective barrier, tightly covering the area above the perforation operation. When the perforation component 7 rotates at high speed and generates iron filings, the arc plate 63 can effectively intercept these flying iron filings. The scraping of iron filings is prevented from scattering and causing potential injury to operators, while also preventing iron filings from falling into other areas of the equipment, reducing the risk of equipment failure. In addition, the special curved surface design of the arc plate 63 can guide the iron filings to slide down the plate surface to the designated position. In conjunction with the permanent magnet 44 and the guide plate 45 of the cleaning mechanism 4, the iron filings are more easily attracted and collected. After the perforation operation is completed, the staff only needs to clean the collection box 46 to complete the iron filings cleaning work, which greatly reduces the cleaning time and workload, significantly improves the efficiency of subsequent cleaning, and ensures the cleanliness of the perforation operation environment and the stable operation of the equipment.
