[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 3 and Figure 4A punching device for processing audio plastic parts includes a processing table 1. Support rods 2 are fixedly connected to the four corners of the upper end of the processing table 1. A support plate 3 is fixedly connected to the upper end of the support rods 2. A cylinder 4 is mounted on the upper end of the support plate 3. A lower pressure plate 5 is fixedly connected to the driving end of the cylinder 4. The end of the lower pressure plate 5 is slidably connected to the outer wall of the support rods 2. A tool mounting plate 6 is connected to the lower side of the lower pressure plate 5 via a buffer assembly. The buffer assembly includes a fixed rod 13 slidably connected to the middle of the lower pressure plate 5. The lower end of the fixed rod 13 is fixedly connected to the upper end of the tool mounting plate 6. A buffer spring 14 is sleeved on the outer wall of the fixed rod 13. The lower end of the buffer spring 14 is fixedly connected to the tool mounting plate 6. The upper end of the mounting plate 6 and the upper end of the buffer spring 14 are fixedly connected to the lower end of the pressure plate 5. The lower end of the tool mounting plate 6 is connected to the punching tool 7 through the clamping assembly. The clamping assembly includes a rotating wheel 19 rotatably connected to the front end of the tool mounting plate 6. A bidirectional screw 20 is fixedly connected to the middle of the rotating wheel 19. A slide groove is opened at the lower end of the tool mounting plate 6. The ends of the bidirectional screw 20 are rotatably connected to both ends of the slide groove. A slider 21 is threadedly connected to both the front and rear sides of the outer wall of the bidirectional screw 20. The ends of the slider 21 are slidably connected to the inside of the slide groove. A clamping block 22 is fixedly connected to the lower end of the slider 21. Guide rods 15 are fixedly connected to both the left and right ends of the tool mounting plate 6.
[0026] Specifically, by rotating the rotary wheel 19 to drive the bidirectional screw 20, the slider 21 and the clamping block 22 can flexibly clamp or release the punching tool 7, making it convenient for operators to quickly change tools according to different processing needs. When the cylinder 4 drives the lower pressure plate 5 to press down, the fixing rod 13 slides in the lower pressure plate 5, and the buffer spring 14 provides buffering force. When the punching tool 7 contacts the plastic parts, the buffer spring 14 is compressed, which can avoid damage to the parts and tools due to excessive instantaneous impact force, making the punching process more stable. The guide rods 15 at both ends of the tool mounting plate 6 provide precise guidance for the up and down movement of the tool mounting plate 6, ensuring that the punching tool 7 can move along the predetermined trajectory, further improving the accuracy of punching.
[0027] Reference Figure 3 and Figure 5A fixed base 8 is fixedly connected to the upper middle part of the processing table 1. A mold mounting plate 11 is fixedly connected to the lower side of the interior of the fixed base 8. The upper end of the mold mounting plate 11 is connected to the lower mold 12 through a positioning component. The positioning component includes a motor 18 installed at the lower end of the mold mounting plate 11. A gear 25 is fixedly connected to the drive end of the motor 18. A slide groove is opened at the upper end of the mold mounting plate 11. The lower end of the gear 25 is rotatably connected in the slide groove. Two racks 24 are meshed on the outer wall of the gear 25. A slider 23 is fixedly connected to the opposite end of the rack 24. The lower end of the slider 23 is slidably connected to the inner wall of the slide groove. A clamping block 26 is fixedly connected to the upper end of the slider 23. The positioning component also includes bolt holes 28 opened on the front and rear sides of the upper end of the mold mounting plate 11. Positioning bolts 27 are threadedly connected inside the bolt holes 28.
[0028] Specifically, by starting the motor 18, the drive end of the motor 18 drives the gear 25 to rotate, which in turn drives the rack 24 to move in opposite directions. The rack 24 drives the slider 23 to move in opposite directions, which in turn causes the clamping block 26 to clamp the lower mold 12. Through the gear 25 and rack 24 structure and the positioning bolt 27, the lower mold 12 can be easily replaced and accurately positioned, and the mold will not be displaced during the punching process, thus ensuring the punching accuracy of the audio plastic parts.
[0029] Reference Figure 2 and Figure 3 A blower 10 is installed at the rear end of the processing table 1. A duct 16 is fixedly connected to the air outlet of the blower 10. The other end of the duct 16 is fixedly connected to the rear end of the fixed base 8. An air hole 17 is opened on the upper side of the interior of the fixed base 8. A collection box 9 is slidably connected inside the processing table 1 for collecting waste materials.
[0030] Specifically, the blower 10 is started, and the blower 10 blows air into the fixed base 8 through the air duct 16. The air duct 17 blows the debris generated during punching into the collection box 9, which avoids the accumulation of debris affecting the punching effect and equipment operation, keeps the processing area clean, and also helps to extend the service life of the equipment. The collection box 9 can conveniently collect the waste generated during punching, which is convenient for subsequent centralized treatment and keeps the working environment clean.
[0031] Working principle: When punching plastic parts, cylinder 4 is first started. Cylinder 4 drives the lower pressure plate 5 to slide down along the support rod 2, which in turn drives the tool mounting plate 6 and the punching tool 7 to move down, thereby punching the plastic parts of the speaker placed on the lower mold 12. When the punching tool 7 contacts the plastic parts, the buffer spring 14 is compressed, which can avoid damage to the parts and tools due to excessive instantaneous impact force, making the punching process more stable. During the punching process, the blower 10 is started. The blower 10 blows air into the fixed seat 8 through the air pipe 16, and blows the debris generated by punching into the collection box 9 through the air hole 17, which is convenient for subsequent centralized treatment and keeps the working environment clean.
[0032] When processing different plastic parts and needing to change the cutting tools and molds, the rotating wheel 19 can be rotated, which drives the bidirectional screw 20 to rotate, thereby causing the slider 21 and clamping block 22 on both sides to move towards or away from each other, to clamp or loosen the punching tool 7, facilitating tool replacement and fixation; the mold can be replaced by loosening the positioning bolt 27 and then starting the motor 18, which drives the gear 25 to rotate, and the rack 24 meshing with the gear 25 drives the slider 23 and clamping block 26 to move, thereby loosening the clamping of the lower mold 12, facilitating the replacement of the lower mold 12.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
