Description

Technical Field

[0001] The utility model relates to the technical field of laser die cutting dies, in particular to a disassembly and assembly component for a laser punching die cutting die. Background Technique

[0002] The laser punching process is a thermophysical process of the interaction between the laser and the material. It is determined by the characteristics of the laser beam (including the wavelength, pulse width, beam divergence angle, focusing state, etc.) of the laser and many thermophysical properties of the material. By irradiating the material to be processed with a high-power density laser beam, the material is quickly heated to the vaporization temperature and evaporated to form holes. Laser punching is the earliest laser processing technology to reach practical application and is also one of the main application fields of laser processing. It is classified as laser removal in laser processing, also called evaporation processing. A laser die cutting die is one of the main components of a laser punching device.

[0003] In a Chinese patent for a laser die cutting die that is easy to install and disassemble (patent number: CN216968024U), the device includes a laser die cutting die installation and disassembly mechanism. The laser die cutting die installation and disassembly mechanism includes an installation frame located at its middle position, and also includes a limit placement groove located inside the installation frame. The limit placement groove and the installation frame are of an integral structure. A laser die cutting die body is arranged inside the limit placement groove. It also includes a side limit fixing mechanism, and there are four side limit fixing mechanisms. The four side limit fixing mechanisms are threadedly installed on the four faces of the outer wall of the installation frame. By installing the laser die cutting die body in the limit placement groove, the installation frame plays an external limiting role, and the side limit fixing mechanism plays a role of four-sided limiting and fixing, so that the internal laser die cutting die body can remain stable during internal processing and no longer requires a threaded component for combined installation, thus facilitating the user to install and disassemble. However, this die cutting die does not have the function of positioning the workpiece to be laser punched. Once the workpiece deviates during the laser punching process, it is easy to affect the accuracy of laser punching, thereby affecting the processing quality. Summary of the Utility Model

[0021] Please refer to Figures 1 to 4 Figures 1 to 4 , in this practical embodiment, a disassembly and assembly component for a laser drilling die includes a die holder 1 and a die body 2. An installation groove 3 is formed in the upper side wall of the die holder 1, and the die body 2 is placed in the installation groove 3. The die holder 1 is a hollow structure, and an installation mechanism is provided in the die holder 1. Two card slots 4 are formed in both side walls of the die body 2, and the four ends of the installation mechanism are respectively inserted into the four card slots 4. A bottom plate shell 5 is fixedly connected to the bottom of the die holder 1, and a clamping mechanism is provided in the bottom plate shell 5. The four ends of the clamping mechanism respectively pass through both sides of the bottom plate shell 5 and extend above the die holder 1 and are fixedly connected to two symmetrically arranged clamping plates 6;

[0022] The clamping mechanism includes a first handwheel rod 7 inserted into and rotatably connected to one side of the bottom plate shell 5. One end of the first handwheel rod 7 is fixedly connected to a worm 8. The inner wall of the bottom plate shell 5 is rotatably connected by a rotating shaft 9 to a worm gear 10 meshed with the worm 8. A circular gear 11 is fixedly connected to the rotating shaft 9. Two racks 12 that are both meshed with the circular gear 11 are slidably connected to the inner walls of the two diagonal sides of the bottom plate shell 5. The far ends of the two racks 12 are both fixedly connected to a first U-shaped frame 13. The two first U-shaped frames 13 respectively penetrate through both ends of the bottom plate shell 5 and are fixedly connected to the two clamping plates 6. When it is necessary to position the workpiece on the die body 2, rotate the first handwheel rod 7. Since the worm 8 is meshed with the worm gear 10, the rotating shaft 9 is driven to rotate. Since the rotating shaft 9 is meshed with the two racks 12 respectively, at this time, the two racks 12 are forced to displace towards each other, and then the two clamping plates 6 fixed to the two first U-shaped frames 13 are pulled to clamp the workpiece for positioning, preventing deviation and ensuring the accuracy of laser drilling processing. The operation is simple.

[0023] As Figure 2 and Figure 4As shown in the figure: The installation mechanism includes a second handwheel rod 14 inserted into the front side wall of the die holder 1 and rotatably connected thereto. One end of the second handwheel rod 14 penetrates into the die holder 1 and is fixedly connected with a driving bevel gear 15. Both inner walls at the two ends of the die holder 1 are rotatably connected with lead screws 16 through bearing seats. One ends of the two lead screws 16 close to each other are fixedly connected with driven bevel gears 17 meshed with the driving bevel gear 15. Nut blocks 18 are threadedly connected to the two lead screws 16. Moving frames 19 are fixedly connected to the same sides of the two nut blocks 18. Two clamping blocks 20 are fixedly connected to the opposite sides of the two moving frames 19. The four clamping blocks 20 are respectively inserted into the four card slots 4. When it is necessary to disassemble the die body 2, rotate the second handwheel rod 14. Since the driving bevel gear 15 meshes with the two driven bevel gears 17, the two lead screws 16 are driven to rotate. Since the two lead screws 16 are respectively threadedly connected with the two nut blocks 18, at this time, the two nut blocks 18 are forced to displace in opposite directions, thereby driving the clamping blocks 20 fixed to the moving frames 19 to displace until the clamping blocks 20 are completely separated from the card slots 4. At this time, the displacement of the die body 2 is no longer restricted, and the die body 2 can be taken out from the installation slot 3 on the die holder 1 to complete the disassembly. The disassembly and assembly are convenient, and the installation and fixation are firm.

[0024] As Figure 4 shown in the figure: A positioning rod 21 is fixedly connected to the inner wall of the die holder 1. Two positioning sliding sleeves 22 are sleeved on and slidably connected to the positioning rod 21. The two positioning sliding sleeves 22 are respectively fixedly connected to the two moving frames 19, making the displacement of the moving frames 19 more stable.

[0025] As Figure 4 shown in the figure: A sliding hole communicating with the installation slot 3 is opened on the inner wall of the die holder 1. The clamping block 20 passes through the sliding hole, which is convenient for the displacement of the clamping block 20.

[0026] As Figure 2 and Figure 3 shown in the figure: Sliders 23 are slidably connected to the inner walls of the bottom plate shell 5 far from the two racks 12. Second U-shaped frames 24 are fixedly connected to the opposite sides of the two sliders 23. The two second U-shaped frames 24 respectively penetrate through the two ends of the bottom plate shell 5 and are fixedly connected to the two clamping plates 6, making the movement of the clamping plates 6 more stable.

[0027] As Figure 3 shown in the figure: The outer side wall of the rotating shaft 9 is fixedly connected by welding to the inner wall of the through holes of the worm gear 10 and the spur gear 11. The connection is firm. The spur gear 11 is located below the worm gear 10 to prevent the worm 8 from rubbing against the spur gear 11.

[0028] Working principle: When it is necessary to disassemble the die body 2, rotate the second handwheel rod 14. Since the driving helical gear 15 meshes with the two driven helical gears 17, the two lead screws 16 are driven to rotate. Since the two lead screws 16 are respectively threadedly connected to the two nut blocks 18, at this time, the two nut blocks 18 are forced to displace in the opposite direction, thereby driving the clamping blocks 20 fixed to the moving frame 19 to displace until the clamping blocks 20 are completely separated from the clamping grooves 4. At this time, the displacement of the die body 2 is no longer restricted, and the die body 2 can be taken out from the installation groove 3 on the die holder 1 to complete the disassembly. The disassembly and assembly are convenient, and the installation and fixation are reliable.

[0029] Secondly, when it is necessary to position the workpiece on the die body 2, rotate the first handwheel rod 7. Since the worm 8 meshes with the worm wheel 10, the rotating shaft 9 is driven to rotate. Since the rotating shaft 9 meshes with the two racks 12 respectively, at this time, the two racks 12 are forced to displace towards each other, thereby pulling the two clamping plates 6 fixed to the two first U-shaped frames 13 to clamp the workpiece for positioning, preventing deviation, and ensuring the accuracy of laser drilling processing. The operation is simple.

[0030] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
