Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, specifically to a micro-hole processing mechanism for CNC punching machines of ultra-thin sheet metal. Background Technology
[0002] In modern manufacturing, micro-hole processing technology is crucial for many high-precision applications, especially in the processing of ultra-thin sheets, where micro-holes enable precise penetration.
[0003] When processing micro-holes in ultra-thin sheets, the process is mostly done by punching. During processing, the sheet is subjected to downward pressure from the punching components. Due to the thinness of the ultra-thin sheet, it may deform under pressure, which will affect the overall performance and aesthetics. In addition, the debris removed from the sheet during the punching operation may splatter and is not easy to collect. Utility Model Content
[0004] The purpose of this invention is to provide a micro-hole processing mechanism for CNC punching machines of ultra-thin sheet metal to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro-hole processing mechanism for CNC punching of ultra-thin sheet metal, comprising a processing table, a support component provided at one edge of the top of the processing table, a moving component provided at the bottom of the support component, a punching component provided at the bottom of the moving component, two frames slidably connected to the top of the processing table, two guides connected together between the two frames, two sliding frames provided at opposite ends of the two guides, two racks provided at both ends of the two frames, with the teeth of the two racks at the same end facing each other, and a gear meshing between the two racks at the same end, a first electric push rod provided at one edge of each of the two guides, a guide rail groove provided at the middle position of the top of the processing table, a moving stage installed inside the guide rail groove via a slider, a pad provided inside the moving stage, a flexible tube connected between the middle position of the bottom of the pad and the moving stage, and a debris collection box detachably installed at the bottom of the moving stage below the flexible tube.
[0006] Preferably, the two sliding frames are grouped together, and each group of sliding frames has an opening at its opposite end. A flexible clamp is provided inside the opening. The two groups of flexible clamps work together to limit the two sides of the plate, so that the plate is fixed at the top of the processing table.
[0007] Preferably, each of the two guides has a limiting groove at its top, and each of the four sliding frames has a screw at its top. The top of the screw passes through the corresponding limiting groove, and the extension end of the screw is provided with a nut. The limiting groove and the screw work together. When the nut on the outer surface of the screw is twisted away from the top of the guide, the sliding frame can move linearly inside the guide to adjust its position. When the sliding frame is adjusted to the predetermined position, the nut is twisted again to make the nut contact the top of the guide, and the sliding frame is locked by friction to prevent the sliding frame from moving during the punching operation.
[0008] Preferably, the bottom of the processing table is provided with two support legs, which support the processing table and ensure the stability of the device.
[0009] Preferably, one end of each of the two first electric push rods is connected to a truss, and a fixing frame is connected between the truss and the processing table. The truss and the fixing frame fix the first electric push rod in the desired position.
[0010] Preferably, the bottom edge of the pad is connected to four second electric push rods between the moving platforms. The second electric push rods can drive the pad to move linearly up and down, so that the top of the pad can be raised to ensure that the pad can contact the bottom of the material to be processed and provide support.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The micro-hole processing mechanism of this ultra-thin sheet metal CNC punching machine uses two frames and two guides connected together. The guides fix sheets of different sizes on the top of the processing table through a sliding frame. A movable table is installed in the middle of the top of the processing table through a guide groove. A pad is set on the top of the movable table. During punching, the two frames can move linearly in both directions on the top of the processing table to adjust the punching position of the sheet metal. This ensures that the punching area of the sheet metal is always located on the top of the pad, so that the area of the sheet metal to be punched is supported by the pad, avoiding deformation of the sheet metal due to downward pressure during punching.
[0013] 2. The micro-hole processing mechanism of this ultra-thin sheet metal CNC punching machine uses a chip collection box located under the pad to collect the chips cut off during the punching process, facilitating centralized processing. Attached Figure Description

[0021] like Figures 1 to 4As shown in the figure, this embodiment discloses a micro-hole processing mechanism for CNC punching of ultra-thin sheet metal, including a processing table 1. A support component 4 is provided at one edge of the top of the processing table 1. The support component 4 is an L-shaped component. A moving component 3 is provided at the bottom of the support component 4. The top of the moving component 3 is mounted on the bottom of the support component 4 via a slider. A punching component is provided at the bottom of the moving component 3. The punching component is a commonly used device in the field of micro-hole processing technology. The top of the punching component is mounted on the bottom of the moving component 3 via a slider. During micro-hole processing, the punching component can move linearly above the processing table 1. Two frames are slidably connected to the top of the processing table 1. The frame 11 has two guides 2 connected together. The two guides 2 are limited by the frame 11, allowing them to move linearly relative to each other at opposite ends of the frame 11. Each opposite end of the two guides 2 is provided with two sliding frames 17, forming a group. Each group of two sliding frames 17 has an opening at its opposite end, allowing the side of the plate to be drilled to be inserted. Two racks 13 are provided at both ends of the two frames 11, with the teeth of the two racks 13 on the same end facing each other. A gear 14 meshes between the two racks 13 on the same end. When the two gears 14 rotate, they engage with two… The rack 13 performs a relative linear motion to pull or push the two frames 11 to perform a relative linear motion, adjusting the distance between the two sets of sliding frames 17. Each of the two guides 2 has a first electric push rod 5 at one end edge. When the output ends of the two first electric push rods 5 are running, they will push or pull the two frames 11 to move. A guide rail groove 10 is provided at the middle position of the top of the processing table 1. A moving table 9 is installed inside the guide rail groove 10 via a slider. A pad 22 is provided inside the moving table 9, and a hole is provided in the middle position of the pad 22. When the two frames 11 move the ultra-thin sheet material, the position of the sheet material to be drilled will... Located above the pad 22, the moving stage 9 moves linearly inside the guide rail groove 10 via a slider, ensuring that the pad 22 is always directly below the punching assembly. During punching, the pad 22 supports the punching position of the sheet metal, preventing the sheet metal from being deformed by downward pressure. The bottom center of the pad 22 is connected to the moving stage 9 via a flexible hose 20. Below the flexible hose 20, the bottom end of the moving stage 9 is detachably equipped with a debris collection box 19. During punching, the punching assembly cuts off some debris from the sheet metal, which falls into the debris collection box 19 for easy collection and centralized processing.
[0022] Specifically, two sliding frames 17 form a group, and each group of sliding frames 17 has an opening at its opposite end. A flexible clamp 18 is installed inside the opening. The two groups of flexible clamps 18 work together to limit the sides of the plate, thus fixing the plate to the top of the processing table 1.
[0023] Furthermore, each of the two guides 2 has a limiting groove 12 on its top, and each of the four sliding frames 17 has a screw 16 on its top. The top of the screw 16 passes through the corresponding limiting groove 12, and the extended end of the screw 16 is provided with a nut 15. The limiting groove 12 and the screw 16 work together. When the nut 15 on the outer surface of the screw 16 is twisted away from the top of the guide 2, the sliding frame 17 can move linearly inside the guide 2 to adjust its position. When the sliding frame 17 is adjusted to the predetermined position, the nut 15 is twisted again to make the nut 15 contact the top of the guide 2, and the sliding frame 17 is locked by friction to prevent the sliding frame 17 from moving during the punching operation.
[0024] Furthermore, the bottom of the processing table 1 is provided with two support legs 6, which support the processing table 1 and ensure the stability of the device.
[0025] Furthermore, one end of each of the two first electric push rods 5 is connected to a truss 8, and a fixing frame 7 is connected between the truss 8 and the processing table 1. The truss 8 and the fixing frame 7 fix the first electric push rods 5 in the required position.
[0026] Furthermore, the bottom edge of the pad 22 is connected to four second electric push rods 21 between the moving platforms 9. The second electric push rods 21 can drive the pad 22 to move linearly up and down, so that the top of the pad 22 can be raised to ensure that the pad 22 can contact the bottom of the plate to be processed and provide support.
[0027] The usage method of this embodiment is as follows: When using the micro-hole processing mechanism of the CNC punching machine for ultra-thin sheet metal, the nut 15 on the outer surface of the screw 16 is turned away from the top of the guide 2. Then, the sliding frame 17 can move linearly inside the guide 2 to adjust its position. Then, the two sides of the sheet metal are respectively inserted into the opening positions of the four sliding frames 17. Then, the flexible clamp 18 is pressed down and used in conjunction with the sliding frame 17 to limit the two sides of the sheet metal, so that the sheet metal is fixed between the guides 2. When the sliding frame 17 is adjusted to the predetermined position, the nut 15 is turned again so that the nut 15 contacts the top of the guide 2. The sliding frame 17 is locked by friction to prevent the sliding frame 17 from moving during the punching operation. Then, the sheet metal is punched by the punching assembly. During the punching process, the sheet metal is punched by the sliding frame 17. The moving table 9 is installed in the guide rail groove 10 via a slider. The pad 22 will always be located directly below the punching assembly. When punching, the pad 22 supports the punching position of the plate, so that the plate will not be deformed by the downward pressure during punching. During punching, the punching assembly will cut off some debris from the plate. The cut debris will fall into the debris collection box 19 for easy collection and centralized processing. The punching assembly can perform linear front and rear movement above the processing table 1. If it is necessary to adjust the punching position in both directions, the two first electric push rods 5 are used to push or pull the two frames 11 to move. By adjusting the position of the plate, the punching position is changed so that the punching area of the plate is always located at the top of the pad 22, avoiding deformation of the plate by the downward pressure of punching.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
