Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more specifically to a stamping equipment for a mobile phone vibrator. Background Technology

[0002] In advanced non-ferrous metal materials, mobile phone oscillators are typically made of precision forged aluminum alloy to provide strength and durability. Stamping equipment is mainly used for precise forming. Mobile phone oscillators usually have dimensional requirements. Stamping equipment can precisely stamp the raw metal sheet through a die, so that the oscillator made of precision forged aluminum alloy can achieve the required shape and dimensional accuracy, ensuring good fit with other internal components of the mobile phone. Using precision forged aluminum alloy for mobile phone oscillators improves strength and durability.

[0003] Among the existing published documents, patent CN218926036U discloses an antenna vibrator stamping device with shockproof effect. This technology uses a push rod that is movably inserted into the surface of the bottom mold, and a stop block is fixedly connected to the surface of the push rod. The bottom surface of the stop block contacts the top surface of the protrusion on the right side of the limiting block. The bottom mold has a cavity for the stop block to move, and a first spring is fixedly connected to the rear end of the stop block. This device is conducive to rapid demolding and improves the use effect of the device; however, this device also has the following defects.

[0004] During the stamping process of mobile phone vibrators, when the upper die closes and the lower die closes to press, the upper die's stamping head generates a large multi-directional vibration wave force the instant it contacts the raw material sheet. This vibration wave force not only causes the upper die and workpiece to have wavy size deviations, but also, since the mobile phone vibrator is made of aluminum alloy precision forging material with higher strength, it increases the difficulty of accurately eliminating vibration. Because it is difficult to effectively combine and accurately eliminate these multi-directional vibration wave forces in both dynamic and static states, the stamping accuracy is poor. Therefore, a stamping equipment for mobile phone vibrators is needed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stamping forming device for a mobile phone vibrator, comprising a lower stamping die, an upper stamping die, and a controller. The upper stamping die is located above the lower stamping die, and a dynamic and static stamping assembly is provided on one side of the upper stamping die. The dynamic and static stamping assembly includes two sleeve blocks disposed on one side of the upper stamping die. A rotating shaft is rotatably connected to the inner wall of each sleeve block, and a rotating rod is fixedly connected to one end of each rotating shaft. A dynamic electromagnet is fixedly installed on the outer wall of the rotating rod. A permanent magnet is provided on one side of the dynamic electromagnet, and an inclined sleeve is fixedly connected to the outer wall of the permanent magnet. An inclined groove is fixedly connected to the lower surface of the inclined sleeve, and a magnetic inclined plate is fixedly connected to the inner wall of the inclined groove. A static electromagnet is fixedly installed on one side of each sleeve block. Both sleeve blocks are fixedly connected to the lower stamping die.

[0006] A gap is provided between the inclined sleeve and the dynamic electromagnet, and the magnetic poles of the dynamic electromagnet and the permanent magnet are of the same polarity on their adjacent sides. Both the inclined sleeve and the inclined groove are fixedly connected to the upper stamping die, and the static electromagnet is arranged parallel to the magnetic inclined plate. Both the dynamic and static electromagnets are electrically connected to the controller. Preferably, multiple vibrating stamping heads are fixedly connected to the lower surface of the upper stamping die, and multiple springs are fixedly installed on the upper surface of the upper stamping die. A sleeve mold is provided at the top of each spring, and multiple springs are fixedly connected to the sleeve mold. Sliding pillars are fixedly connected to the upper surface of the upper stamping die near its four corners, and multiple sliding pillars are slidably connected to the sleeve mold. An mounting sleeve is fixedly connected to the upper surface of the sleeve mold. A sleeve cylinder is fixedly provided on the inner wall of the sleeve mold on both sides of the mounting sleeve, and a guide post is slidably connected to the inner wall of the sleeve cylinder. The guide post is fixedly connected to the lower stamping die. A limiting strip is fixedly connected to the upper surface of the stamping die, and the limiting strip has a concave cross-sectional shape. Each of the sleeves is provided with a hook on one side, and both hooks are fixedly connected to the sleeve die.

[0007] In operation, this technology utilizes a stamping machine's electric cylinder to move the mounting sleeve downwards, which in turn causes a spring to push the upper stamping die downwards. Multiple oscillator stamping heads then contact the mobile phone oscillator material sheet. Simultaneously, the sleeve die guides the sleeve cylinder downwards along the outer wall of the guide post, allowing the multiple oscillator stamping heads to contact the mobile phone oscillator material sheet and complete the stamping process. A sleeve block supports a static electromagnet, which generates an inclined magnetic force on the magnetic inclined plate, preventing the upper stamping die from upward springback fluctuations. Simultaneously, the magnetic inclined plate drives the inclined groove to generate an inclined attraction force, which in turn causes the upper stamping die to generate an inclined attraction force, offsetting some of the springback vibration force caused by the upper stamping die shifting upwards or to the left or right. The rotating shaft rotates inside the sleeve block, and the rotating rod drives the dynamic electromagnet to rotate. When the dynamic electromagnet is opened, it generates magnetic force. Since the adjacent surfaces of the dynamic electromagnet and the permanent magnet are magnetically identical, the dynamic electromagnet continuously rotates the permanent magnet to generate a repulsive force. The permanent magnet can be squeezed to drive the inclined sleeve to generate an inclined repulsive force. The inclined sleeve generates an inclined repulsive force on the stamping die. The repulsive force continuously increases to counteract the rebound residual vibration force of the stamping die shifting upward and to the left and right, until the vibration force sensed by the vibration sensor is zero.

[0008] Preferably, a positioning pressure sensor is fixedly connected to the outer wall of the lower stamping die and located between the two sleeve blocks; a pressure end is provided above the positioning pressure sensor, and a support block is fixedly connected to the top of the pressure end; a support sleeve is fixedly connected to the upper surface of the support block; a vibration sensor is installed inside the support sleeve; both the positioning pressure sensor and the vibration sensor are electrically connected to the controller; both the support block and the support sleeve are fixedly connected to the upper stamping die.

[0009] During operation, the upper stamping die moves downwards, simultaneously causing the support block to move downwards as well. The pressure end contacts the positioning pressure sensor, indicating that multiple oscillator stamping heads have begun to contact the mobile phone oscillator material sheet. The upper stamping die transmits the force to the support block, where a vibration sensor on the support sleeve can detect the vibration wave dynamics.

[0010] Preferably, a sleeve rod is fixedly connected to the other end of the rotating shaft; a slide rod is fixedly connected to one side of the sleeve rod, and an arc-shaped guide rail is slidably connected to the outer wall of the slide rod. The arc-shaped guide rail is slidably connected to the sleeve rod and fixedly connected to the lower stamping die. A slide frame is slidably connected to one side of the arc-shaped guide rail, and the slide rod is slidably connected to the slide frame. A shrinking electric cylinder is installed on the lower surface of the slide frame and fixedly connected to the upper stamping die. The shrinking end of the shrinking electric cylinder is fixedly connected to the slide frame. The controller is fixed to the outer wall of the lower stamping die, and the shrinking electric cylinder is electrically connected to the controller. The outer wall of the slide rod and the inner wall of the arc-shaped guide rail are both smooth surfaces, and the vertical cross-sectional shape of the arc-shaped guide rail is circular. The two arc-shaped guide rails are symmetrically arranged about the shrinking electric cylinder. The inner wall of the slide frame and the outer wall of the slide rod are both smooth surfaces, and the vertical cross-sectional shape of the slide frame is rectangular.

[0011] In use, the controller activates the retraction electric cylinder, which drives the slide frame to move down and retract. The slide rod rotates along the arc path of the arc guide rail, which in turn drives the sleeve rod to rotate. The sleeve rod then drives the rotating shaft to achieve stable guiding rotation.

[0012] The present invention has the following advantages:

[0013] 1. This invention, by setting up dynamic and static stamping components, enables the static electromagnet to generate an inclined magnetic attraction force on the magnetic traction plate, preventing the stamping upper die from upward movement and springback fluctuations. The magnetic traction plate drives the inclined groove strip to generate an inclined attraction force, which offsets part of the springback vibration force of the stamping upper die shifting upward and left and right. At the same time, the rotating shaft rotates inside the sleeve block, and the rotating rod drives the dynamic electromagnet to rotate. When the dynamic electromagnet is opened, it generates magnetic force. Since the adjacent surfaces of the dynamic electromagnet and the permanent magnet have the same magnetic poles, as the dynamic electromagnet continuously rotates on the permanent magnet, it generates a repulsive force of the same magnetic poles. The inclined sleeve strip generates an inclined repulsive force on the stamping upper die. The repulsive force continuously increases to offset the remaining springback vibration force of the stamping upper die shifting upward and left and right. The vibration force sensed by the vibration sensor is zero. Under the combination of the dynamically changing repulsive force and the static inclined magnetic attraction force, the vibration wave force at these multi-directional positions on the stamping upper die can be accurately eliminated, avoiding multi-directional fluctuations when the multiple oscillator stamping heads on the stamping upper die come into contact with the mobile phone oscillator material sheet, and greatly improving the accuracy of stamping.

[0014] 2. In this invention, the upper stamping die moves downwards while the support block moves downwards, and the pressure end contacts the positioning pressure sensor. Multiple oscillator stamping heads make contact with the mobile phone oscillator material sheet. The vibration sensor can sense the vibration wave dynamic value. At the same time, multiple oscillator stamping heads are in contact with the mobile phone oscillator material sheet, and the dynamic and static combination can be quickly and accurately eliminated to eliminate the vibration wave dynamic at multiple positions on the upper stamping die, which greatly improves the accuracy of stamping.

[0015] 3. This invention uses a retractable electric cylinder to move the sliding frame downwards and retracts. The sliding rod rotates along the arc-shaped path of the arc-shaped guide rail, which in turn drives the connecting rod to rotate. The rotating shaft rotates inside the connecting block, and the rotating rod drives the dynamic electromagnet to rotate. This allows for the rotation of two dynamic electromagnets. The arc-shaped guide rail enables precise path movement and efficient power transmission. Furthermore, it allows for precise control of the position and angle of the dynamic electromagnets. Moreover, the close cooperation of all components provides stable and precise movement for the subsequent dynamic magnetic force generated by the dynamic electromagnets. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 - Figure 9 The present invention relates to a stamping forming equipment for mobile phone vibrators. The equipment is equipped with a dynamic and static stamping assembly. The dynamic and static stamping assembly can accurately eliminate the vibration wave dynamics at multiple positions on the upper stamping die 2 under the combined effect of dynamic repulsive force and static tilting magnetic attraction force. This avoids multi-directional fluctuations at the moment when the multiple vibrator stamping heads 22 on the upper stamping die 2 come into contact with the mobile phone vibrator raw material sheet, and greatly improves the accuracy of stamping forming. The specific structural configuration of the dynamic and static stamping assembly is as follows.

[0030] In this embodiment, as Figure 1 - Figure 4As shown, the upper stamping die 2 is located above the lower stamping die 1. A dynamic and static stamping assembly is provided on one side of the upper stamping die 2. The dynamic and static stamping assembly includes two sleeve blocks 3 disposed on one side of the upper stamping die 2. A rotating shaft 4 is rotatably connected to the inner wall of each sleeve block 3, and a rotating rod 5 is fixedly connected to one end of each rotating shaft 4. A dynamic electromagnet 6 is fixedly installed on the outer wall of the rotating rod 5. A permanent magnet 7 is provided on one side of the dynamic electromagnet 6, and an inclined sleeve 8 is fixedly connected to the outer wall of the permanent magnet 7. An inclined groove 9 is fixedly connected to the lower surface of the inclined sleeve 8, and a magnetic inclined plate 10 is fixedly connected to the inner wall of the inclined groove 9. A static electromagnet 11 is fixedly installed on one side of the sleeve block 3. Both sleeve blocks 3 are fixedly connected to the lower stamping die 1. A gap is provided between the inclined sleeve 8 and the dynamic electromagnet 6. The magnetic poles of the adjacent sides of the dynamic electromagnet 6 and the permanent magnet 7 are of the same polarity. The inclined sleeve 8 and the inclined groove 9 are both fixedly connected to the upper stamping die 2, and the static electromagnet 11 is arranged parallel to the magnetic inclined plate 10; the dynamic electromagnet 6 and the static electromagnet 11 are both electrically connected to the controller 30.

[0031] In this embodiment, as Figure 4 - Figure 5 As shown, a positioning pressure sensor 12 is fixedly connected to the outer wall of the lower stamping die 1 and between two sleeve blocks 3; a pressure end 13 is provided above the positioning pressure sensor 12, and a support block 14 is fixedly connected to the top of the pressure end 13. A support sleeve 15 is fixedly connected to the upper surface of the support block 14. A vibration sensor 16 is installed inside the support sleeve 15. Both the positioning pressure sensor 12 and the vibration sensor 16 are electrically connected to the controller 30; both the support block 14 and the support sleeve 15 are fixedly connected to the upper stamping die 2.

[0032] In this embodiment, as Figure 7 - Figure 8 As shown, a sleeve rod 17 is fixedly connected to the other end of the rotating shaft 4; a slide rod 18 is fixedly connected to one side of the sleeve rod 17, and an arc-shaped guide rail 19 is slidably connected to the outer wall of the slide rod 18. The arc-shaped guide rail 19 is slidably connected to the sleeve rod 17, and is fixedly connected to the lower stamping die 1. A slide frame 20 is slidably connected to one side of the arc-shaped guide rail 19, and is slidably connected to the slide rod 18 and the slide frame 20. A shrinking electric cylinder 21 is installed on the lower surface of the slide frame 20, and is fixedly connected to the upper stamping die 2. The shrinking end of the shrinking electric cylinder 21 is fixedly connected to the slide frame 20. The controller 30 is fixed on the outer wall of the lower stamping die 1, and is electrically connected to the shrinking electric cylinder 21 and the controller 30. The outer wall of the slide rod 18 and the inner wall of the arc-shaped guide rail 19 are both smooth surfaces, and the vertical cross-section of the arc-shaped guide rail 19 is arc-shaped. The two arc-shaped guide rails 19 are symmetrically arranged about the shrinking electric cylinder 21. The inner wall of the sliding frame 20 and the outer wall of the sliding rod 18 are both smooth surfaces, and the vertical cross-section of the sliding frame 20 is rectangular.

[0033] In this embodiment, as Figure 9 As shown, multiple vibrating stamping heads 22 are fixedly connected to the lower surface of the upper stamping die 2, and multiple springs 23 are fixedly installed on the upper surface of the upper stamping die 2. Each spring 23 has a connecting die 24 at its top, and all springs 23 are fixedly connected to the connecting die 24. Sliding columns 31 are fixedly connected to the upper surface of the upper stamping die 2 near its four corners, and all sliding columns 31 are slidably connected to the connecting die 24. Mounting sleeves 25 are fixedly connected to the upper surface of the connecting die 24. Connecting sleeves 26 are fixedly installed on the inner wall of the connecting die 24 on both sides of the mounting sleeves 25. Guide columns 27 are slidably connected to the inner wall of the connecting sleeves 26, and the guide columns 27 are fixedly connected to the lower stamping die 1. Limiting strips 28 are fixedly connected to the upper surface of the lower stamping die 1, and the cross-sectional shape of the limiting strips 28 is concave. Each connecting sleeve 26 has a hook 29 on one side, and both hooks 29 are fixedly connected to the connecting die 24.

[0034] This allows the factory overhead crane to be used to lift the hook 29, which in turn moves the connecting mold 24, facilitating its later transfer. During use, the mounting sleeve 25 is threaded and locked to the output end of the stamping machine's electric cylinder. Then, the mobile phone vibrator material is placed in the inner wall of the limiting strip 28. The stamping machine's electric cylinder pushes the mounting sleeve 25 downwards, and the spring 23 pushes the upper stamping die 2 downwards. The upper stamping die 2 moves multiple vibrator stamping heads 22 downwards, and the connecting mold 24 guides the connecting cylinder 26 to slide down along the outer wall of the guide post 27. When the vibrator stamping head 22 contacts the mobile phone vibrator material, the connecting mold 24 slides down along the outer wall of multiple sliding columns 31, achieving multi-point guided stamping forming.

[0035] The process of using the stamping and forming equipment for the mobile phone vibrator of this invention is as follows:

[0036] Step 1: During the stamping process, the material used for the mobile phone vibrator raw material plate is aluminum alloy precision forging, which has high strength and better durability. Once the material for the mobile phone vibrator raw material plate is determined, the mounting sleeve 25 can be threaded and locked to the output end of the stamping machine cylinder. Then, the mobile phone vibrator raw material plate is placed in the inner wall of the limiting strip 28, while the stamping die 1 supports the mobile phone vibrator raw material plate. Then, the mounting sleeve 25 is pushed down by the electric cylinder of the stamping machine. The mounting sleeve 25 drives the spring 23 to move down, and the spring 23 pushes the upper stamping die 2 to move down. The upper stamping die 2 drives multiple vibrator stamping heads 22 to move down. The multiple vibrator stamping heads 22 contact the mobile phone vibrator material plate. At the same time, the sleeve die 24 drives the sleeve cylinder 26 to slide down along the outer wall of the guide post 27. The multiple vibrator stamping heads 22 can contact the mobile phone vibrator material plate to complete the stamping operation. The sleeve die 24 slides down along the outer wall of multiple sliding columns 31. At the same time as the stamping contact, the multiple vibrator stamping heads 22 will generate a large vibration wave force.

[0037] Step 2: During positioning sensing, as the upper stamping die 2 moves downwards for stamping, it also moves the support block 14 downwards. The support block 14 then moves the pressure end 13 downwards. The pressure end 13 presses against the positioning pressure sensor 12, indicating that the multiple oscillator stamping heads 22 are now in contact with the mobile phone oscillator material sheet. Simultaneously, the oscillator stamping heads 22 transmit the force to the upper stamping die 2, which in turn transmits it to the support block 14. The support block 14 then transmits it to the support sleeve 15, where the vibration sensor 16 senses the vibration wave dynamic value.

[0038] Step 3, during static processing, two sleeve blocks 3 are supported by the lower stamping die 1. The sleeve blocks 3 support the static electromagnet 11. The controller 30 supplies power to the static electromagnet 11. The static electromagnet 11 generates an inclined magnetic attraction force on the magnetic suction plate 10. As a result, the static electromagnet 11 moves downward stably under the inclined magnetic attraction force, and avoids the upper stamping die 2 from upward rebound fluctuations. At the same time, the magnetic suction plate 10 drives the inclined groove 9 to generate an inclined attraction force. The inclined groove 9 enables the upper stamping die 2 to generate an inclined attraction force. Thus, under the influence of the static inclined attraction force of the static electromagnet 11, the upper stamping die 2 offsets part of the rebound vibration force of the upper stamping die 2 shifting upward and to the left and right.

[0039] Step 4: During dynamic processing, the retraction cylinder 21 is activated simultaneously via the controller 30. The retraction cylinder 21 drives the sliding frame 20 to move down and retract. The sliding frame 20 drives the two sliding rods 18 to move down, while the sliding rods 18 rotate along the arc path of the arc guide rail 19. The sliding rods 18 drive the sleeve rod 17 to rotate, and the sleeve rod 17 drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates inside the sleeve block 3, and the rotating shaft 4 drives the rotating rod 5 to rotate. The rotating rod 5 drives the dynamic electromagnet 6 to rotate. After the dynamic electromagnet 6 is opened, it generates magnetic force. Since the adjacent surfaces of the dynamic electromagnet 6 and the permanent magnet 7 are magnetically identical, the rotation of the dynamic electromagnet 6 will generate an inclined magnetic repulsive force on the permanent magnet 7. As the dynamic electromagnet 6 continuously rotates the permanent magnet 7 to generate a repulsive force, the permanent magnet 7 is squeezed and drives the inclined sleeve 8 to generate an inclined repulsive force. The inclined sleeve 8 generates an inclined repulsive force on the stamping die 2. In this way, the dynamic electromagnet 6 will continuously rotate to adjust the magnitude of the inclined repulsive force, so that the repulsive force will continuously increase to counteract the rebound residual vibration force of the stamping die 2 shifting upward and left and right. When the vibration force sensed by the vibration sensor 16 is zero, the vibration wave force of the multiple oscillator stamping heads 22 on the stamping die 2 is precisely canceled out, ensuring that the multiple oscillator stamping heads 22 on the stamping die 2 stably stamp and form the mobile phone oscillator material sheet.
