[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

Therefore, the above terms cannot be understood as limiting the present invention.

[0026] In the description of this utility model, if the word "several" or "several" is used, it means one or more, and "more" means two or more. "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the words "first," "second," and "third" is only for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0027] The following is combined with Figure 1-5 , an embodiment of a hole-opening device for a curved vibrator of the utility model is further described in detail.

[0028] A hole-opening device for a curved oscillator, such as Figures 1 to 4 As shown, it includes a workbench 1, a mold bracket 2 arranged on the workbench 1, a punching mold 3 located in the mold bracket 2, and a hydraulic drive mechanism 4 connected to the punching mold 3. The punching mold 3 includes a punch stamping assembly 31 and a die positioning assembly 32. A mold cavity 8 for punching a curved vibrator is provided on one side of the die positioning assembly 32. A punching block 5 is provided in the mold cavity 8. The surface of the punching block 5 is provided with a wavy structure adapted to the curved vibrator to form a plurality of opening stations for punching the curved vibrator. Punching holes 51 are symmetrically provided at the top of the punching block 5. A positioning insert 6 cooperating with the punch stamping assembly 31 is provided on one side of the punching hole 51.

[0029] Specifically, since the curved vibrator needs to have through holes at both ends, the traditional manual hole-opening method is not only inefficient but also has low precision, and the existing hole-opening equipment can only open holes for a single curved vibrator, which also makes its production efficiency low. For this reason, the utility model uses a punching die 3 to simultaneously bend and open holes on the vibrator. When bending and opening holes, the vibrator to be processed is placed on the stamping block 5 of the die positioning assembly 32, and the hydraulic drive mechanism 4 is used to drive the punch stamping assembly 31 and the die positioning assembly 32 to close the mold, so that the vibrator on the stamping block 5 is bent and opened on one side under the stamping action of the punch stamping assembly 31. Then, the curved vibrator that has completed the single-sided opening is reversed and re-stamped to obtain a curved vibrator with double-sided openings.

[0030] It is worth mentioning that the hole-opening device of the utility model can be externally connected to an online measurement system, which can monitor the bending of the vibrator and the hole-opening process parameters in real time, including the vibrator position, bending angle, hole-opening depth, etc., to ensure processing accuracy and consistency; among them, the measurement system adopts advanced optical sensing technology and data analysis algorithms, which can quickly respond and feedback the measurement results, and guide the optimization and adjustment of subsequent processing steps.

[0031] In this embodiment, if Figure 2 As shown, the punch stamping assembly 31 includes an upper die base 311, an ejector pin 315 plate 312 and a stamping plate 313. A plurality of spring guides 314 and ejector pins 315 are connected between the upper die base 311 and the stamping plate 313. The spring guides 314 and ejector pins 315 respectively pass through the ejector pin 315 plate 312 and are connected to the stamping plate 313. The ejector pins 315 are used to fix and clamp the stamping plate 313 so that it does not move. A plurality of positioning guide pins 316 are provided on both sides of the bottom edge of the stamping plate 313. The positioning guide pins 316 are used to position and guide the up and down movement of the die plate to ensure the accurate position of the ejector pins 315 between the punch 7 and the punching plate.

[0032] Specifically, a punch 7 is provided at the position of the punching plate 313 corresponding to the punching hole 51, and the punch 7 can move through the punching hole 51. Among them, the punch 7 is the most important component of the punching die 3. It is used to produce a hole of the shape and size required for the vibrator. In addition, a punching cavity adapted to the punching block 5 is provided at the position of the punch 7, so that when the punching plate 313 and the punching block 5 are pressed together, the wave structure of the punching block 5 can perfectly fit into the punching cavity, so that the vibrator is punched into a curved structure; and the working process of the punching die 3 includes two stages: upstroke and downstroke:

[0033] Upstroke: The upstroke is the first step in the punching die 3's operation, during which the punch 7 is pressed downward, striking the vibrator. During this process, the ejector pin 315 drives the punch plate 313 and the punch 7 downward until the punch 7 inserts the vibrator into the punched hole to the desired depth, forming a hole.

[0034] Downstroke: The downstroke is the second step in the punching die 3's operation. The ejector pin 315 quickly rises, and the punch plate 313 and punch 7 also rise. During this process, the die positioning assembly 32 holds the vibrator in place, preventing it from moving.

[0035] In this embodiment, if Figure 5 As shown, the die positioning assembly 32 includes a lower die base 321, a clamping limit strip 323 and a positioning block 324. The lower die base 321 is fixedly connected to a stamping core 322. The clamping limit strip 323 is symmetrically arranged on the stamping core 322, and the clamping limit strip 323 is provided with a limiting groove 3231 for clamping and fixing the curved vibrator; a plurality of positioning blocks 324 are provided, and the plurality of positioning blocks 324 are respectively arranged at the ends of the clamping limit strip 323.

[0036] Specifically, when stamping vibrators in batches, the limit groove 3231 on the clamping limit bar 323 is used to clamp the vibrator, and the positioning of the vibrator stamping position is quickly completed through the positioning block 324, ensuring the stability and positioning accuracy of the vibrator during the processing process, and avoiding processing errors caused by vibration or displacement; thereby, the vibrator can be moved in sequence along the direction of the clamping limit groove 3231 to the stamping block 5 to complete the hole opening operation.

[0037] In this embodiment, a plurality of positioning guide sleeves 325 are provided on both sides of the top edge of the stamping core 322 , and the positioning guide sleeves 325 are cooperatively connected with the positioning guide posts 316 .

[0038] Specifically, by providing a positioning guide sleeve 325, it can be used to position and guide the ejector pin 315 and positioning guide pin 316 on the punch plate 313, allowing them to smoothly complete the up and down movement, while also ensuring that the punch plate 313 and the punch core 322 are tightly fitted together. Furthermore, a clearance groove 3221 is provided on the punch core 322, located between the clamping limit block and the positioning block 324. This avoids collision between the punch plate 313 and the punch core 322 during punching, ensuring their accurate alignment.

[0039] In this embodiment, if Figure 1 As shown, the mold support 2 includes an upper connecting plate 21, a guide column 22 and a lower fixed plate 23. There are multiple guide columns 22, and the two ends of the multiple guide columns 22 are respectively connected to the upper connecting plate 21 and the lower fixed plate 23, and a reset spring is provided on the outer side of the guide column 22.

[0040] Specifically, the mold support 2 can support the punching mold 3, and at the same time can assist in completing the mold closing and mold opening guidance of the punching mold 3 through the guide column 22, thereby improving the accuracy of the hole opening; setting a reset spring on the outside of the guide column 22 can quickly reset the punch stamping assembly 31 and the die positioning assembly 32 after completing the mold closing, while improving the service life of the mold support 2.

[0041] In this embodiment, the hydraulic drive mechanism 4 includes a hydraulic cylinder 41 and an output shaft 42. The hydraulic cylinder 41 is fixedly connected to the top of the mold support 2, and the hydraulic cylinder 41 is transmission-connected to the output shaft 42; one end of the output shaft 42 passes through the upper connecting plate 21 and is connected to the punch stamping assembly 31.

[0042] Specifically, the hydraulic drive mechanism 4 serves as the core driving force, which is mainly responsible for providing the necessary power output to ensure that the punching die 3 can smoothly perform bending and hole opening operations. At the same time, the driving source selects the hydraulic cylinder 41, which can maintain continuous and stable output, and drives the punching die 3 through the output shaft 42 to complete the mold closing and mold opening actions, so that it can efficiently complete the bending and hole opening work of the vibrator.

[0043] The working principle of this utility model:

[0044] When manufacturing a curved vibrator, a metal iron sheet is placed in a stamping die and limited by a clamping limit bar 323 and a positioning block 324. After positioning, the vibrator drives the punch stamping assembly 31 and the die positioning assembly 32 to close the mold under the action of the hydraulic drive mechanism 4. After closing the mold, the punch stamping assembly 31 is wedged with the stamping block 5, so that the multiple vibrators placed on the stamping block 5 are stamped and bent into a curved shape under the stamping action of the punch stamping assembly 31, and the single-sided opening operation is completed at the same time. After the curved vibrator with the single-sided opening is reversed, the above steps are repeated to complete the double-sided opening of the curved vibrator; thereby, precise bending and opening processing of the curved vibrator is achieved, and multiple products can be produced simultaneously in a single working condition, thereby improving production efficiency.

[0045] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
