Description

Technical Field

[0001] The present invention relates to the technical field of stamping and forming, and in particular to a stamping and forming device for a mobile phone vibrator. Background Art

[0002] Among advanced non-ferrous metal materials, mobile phone vibrators usually use aluminum alloy precision die forgings to provide strength and durability. Stamping equipment is mainly used for precise forming. Mobile phone vibrators usually have size requirements. Stamping equipment can use molds to perform precise stamping on metal sheet raw materials, so that the vibrator made of aluminum alloy precision die forgings can achieve the shape and size accuracy required by the design, ensuring its good fit with other internal components of the mobile phone. Aluminum alloy precision die forgings are used as mobile phone vibrators to improve strength and durability.

[0003] In the existing public literature, patent number CN218926036U discloses an antenna vibrator stamping device with a shock-proof effect. This technology is achieved by movably inserting a push rod on the surface of the bottom mold, and a block is fixedly connected to the surface of the push rod. The bottom surface of the block contacts the top surface of the protrusion on the right side of the limit block. The interior of the bottom mold is provided with a cavity for the block to move, and the rear end of the block is fixedly connected to a first spring. This device is conducive to rapid demoulding and improves the use effect of the equipment; however, the device still has the following defects.

[0004] During the stamping process of mobile phone vibrators, when the upper mold is pressed downward and closed with the lower mold, a large multi-directional vibration wave force will be generated at the moment the upper mold punch head contacts the raw material plate. This vibration wave force will not only cause the upper mold and the workpiece to have corrugation size deviations, but the mobile phone vibrator is made of aluminum alloy precision die forgings with higher strength, which also increases the difficulty of accurately eliminating vibration. Since it is difficult to effectively combine and accurately eliminate these multi-directional vibration wave forces in dynamic and static states, the stamping accuracy is poor. Therefore, a stamping forming device for mobile phone vibrators is needed. Summary of the Invention

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

[0006] A gap is provided between the inclined sleeve and the dynamic electromagnet, and the magnetic poles of the dynamic electromagnet on the side adjacent to the permanent magnet are arranged with the same polarity. The inclined sleeve and inclined slot are both fixedly connected to the stamping upper die, and the static electromagnet is arranged parallel to the magnetic attraction inclined plate; the dynamic electromagnet and the static electromagnet are both electrically connected to the controller. Preferably, a plurality of vibrator punches are fixedly connected to the lower surface of the stamping upper die, and a plurality of springs are fixedly installed on the upper surface of the stamping upper die, and a sleeve die is provided at the top of each spring, and the plurality of springs are fixedly connected to the sleeve die; sliding posts are fixedly connected to the upper surface of the stamping upper die and near its four corners, and the plurality of sliding posts are slidably connected to the sleeve die, and the upper surface of the sleeve die is fixedly connected to a mounting sleeve; sleeve cylinders are fixedly provided on the inner wall of the sleeve die and located on both sides of the mounting sleeve, and the inner wall of the sleeve cylinder is slidably connected to a guide post, and the guide post is fixedly connected to the stamping lower die. The upper surface of the punching lower die is fixedly connected to a limit bar, the cross section of which is concave. A hook is provided on one side of each sleeve, and both hooks are fixedly connected to the sleeve die.

[0007] When using this technology, the stamping machine's electric cylinder pushes the mounting sleeve downward, and the spring pushes the stamping die downward. Multiple vibrator punches contact the mobile phone vibrator raw material sheet. At the same time, the socket die drives the socket tube to slide down along the outer wall of the guide column. Multiple vibrator punches can contact the mobile phone vibrator raw material sheet to complete the stamping operation. The socket block supports the static electromagnet, which generates an inclined magnetic attraction force on the magnetic attraction ramp to prevent the stamping die from upward rebound fluctuations. At the same time, the magnetic attraction ramp drives the inclined groove to generate an inclined attraction force. The inclined groove can generate an inclined attraction force on the stamping die, offsetting some of the rebound vibration force caused by the upward and left and right deviation of the stamping die. The rotating shaft rotates inside the socket block, and the rotating rod drives the dynamic electromagnet to rotate. The dynamic electromagnet generates magnetic force when it is turned on. Since the adjacent surfaces of the dynamic electromagnet and the permanent magnet have the same magnetic poles, 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 upper die. The repulsive force continues to increase to offset the rebound residual vibration force of the stamping upper die upward and left and right deviations 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 stamping lower die and located between the two socket 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, and the upper surface of the support block is fixedly connected to a support sleeve, and a vibration sensor is installed inside the support sleeve, and the positioning pressure sensor and the vibration sensor are both electrically connected to the controller; the support block and the support sleeve are both fixedly connected to the stamping upper die.

[0009] When this technology is used, the downward movement of the upper punch moves the support block, simultaneously with the pressing action. The pressing end contacts the positioning pressure sensor, indicating that the multiple vibrator punches have made contact with the mobile phone vibrator raw material sheet. The pressure from the upper punch is transmitted to the support block, and the vibration sensor on the support sleeve can sense the vibration wave force value.

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

[0011] When this technology is in use, the controller is used to start the retraction electric cylinder, which drives the slide frame to move downward and retract. The slide rod rotates along the arc path of the arc guide rail, and the slide rod drives the sleeve rod to rotate. The sleeve rod drives the rotating shaft to stably realize the guided rotation.

[0012] The present invention has the following advantages: 1. The present invention sets a dynamic and static stamping component so that the static electromagnet generates an inclined magnetic attraction force on the magnetic attraction ramp, thereby preventing the stamping upper die from moving upward and rebounding fluctuations. The magnetic attraction ramp drives the inclined groove to generate an inclined attraction force, thereby offsetting a part of the rebound vibration force of the stamping upper die deviating upward and leftward. At the same time, the rotating shaft rotates inside the sleeve block, and the rotating rod drives the dynamic electromagnet to rotate. The dynamic electromagnet generates a magnetic force after it is turned on. Since the adjacent surfaces of the dynamic electromagnet and the permanent magnet have the same magnetic poles, as the dynamic electromagnet continuously rotates the permanent magnet to generate a same-pole repulsive force, the inclined sleeve generates an inclined repulsive force on the stamping upper die, and the repulsive force continues to increase to offset the rebound residual vibration force of the stamping upper die deviating upward and leftward. The vibration force sensed by the vibration sensor is zero. Under the combination of the dynamic changing repulsive force and the static inclined magnetic attraction force, the vibration wave force in multiple directions of the stamping upper die can be accurately eliminated, thereby avoiding the multi-directional fluctuation of the multiple vibrator punching heads on the stamping upper die at the moment of contacting the mobile phone vibrator raw material plate, thereby greatly improving the accuracy of stamping forming. 2. The present invention uses the downward movement of the stamping upper die to drive the support block to move downward while stamping. The pressing end squeezes and contacts the sensing force of the positioning pressure sensor. Multiple vibrator punching heads are in contact with the raw material plate of the mobile phone vibrator. The vibration sensor can sense the vibration wave force value. While multiple vibrator punching heads are in contact with the raw material plate of the mobile phone vibrator, it can quickly combine dynamic and static to accurately eliminate the vibration wave forces in multiple directions on the stamping upper die, thereby greatly improving the accuracy of stamping.

[0013] 3. The present invention drives the sliding frame to move downward and retract by setting a contraction electric cylinder, and the sliding rod rotates along the arc path of the arc guide rail. The sliding rod drives the sleeve rod to rotate, and the rotating shaft rotates inside the sleeve block. The rotating rod drives the dynamic electromagnet to rotate, so that the two dynamic electromagnets can be rotated, and precise path movement can be achieved with the help of the arc guide rail, and power can be transmitted efficiently. Secondly, the position and angle of the dynamic electromagnet can be accurately controlled, and the various components work closely together to provide stable and precise movement for the subsequent dynamic electromagnet to generate dynamic magnetic force.

[0020] In this embodiment, if Figure 4 - Figure 5 As shown, a positioning pressure sensor 12 is fixedly connected to the outer wall of the stamping lower die 1 and located between the two socket 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, and a support sleeve 15 is fixedly connected to the upper surface of the support block 14, and a vibration sensor 16 is installed inside the support sleeve 15. The positioning pressure sensor 12 and the vibration sensor 16 are both electrically connected to the controller 30; the support block 14 and the support sleeve 15 are both fixedly connected to the stamping upper die 2.

[0021] In this embodiment, if Figure 7 - Figure 8 As shown, the other end of the rotating shaft 4 is fixedly connected to a sleeve rod 17; a slide rod 18 is fixedly connected to one side of the sleeve rod 17, and an arcuate guide rail 19 is slidably connected to the outer wall of the slide rod 18. The arcuate guide rail 19 and the sleeve rod 17 are slidably connected, and the arcuate guide rail 19 is fixedly connected to the stamping lower die 1. A slide frame 20 is slidably connected to one side of the arcuate guide rail 19, and the slide rod 18 and the slide frame 20 are slidably connected. A retraction electric cylinder 21 is mounted on the lower surface of the slide frame 20, and the retraction electric cylinder 21 is fixedly connected to the stamping upper die 2. The retraction end of the retraction electric cylinder 21 is fixedly connected to the slide frame 20. A controller 30 is fixed to the outer wall of the stamping lower die 1, and the retraction electric cylinder 21 and the controller 30 are electrically connected. The outer wall of the slide rod 18 and the inner wall of the arcuate guide rail 19 are both smooth surfaces, and the vertical cross-section of the arcuate guide rail 19 is an arc. The two arcuate guide rails 19 are symmetrically arranged about the retraction 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.

[0022] In this embodiment, if Figure 9 As shown, the lower surface of the stamping upper die 2 is fixedly connected to a plurality of vibrator punching heads 22, and the upper surface of the stamping upper die 2 is fixedly installed with a plurality of springs 23. The top of the spring 23 is provided with a sleeve die 24, and the plurality of springs 23 are fixedly connected to the sleeve die 24; the upper surface of the stamping upper die 2 and near its four corners are fixedly connected to sliding posts 31, and the plurality of sliding posts 31 are slidably connected to the sleeve die 24, and the upper surface of the sleeve die 24 is fixedly connected to a mounting sleeve 25; the inner wall of the sleeve die 24 and the positions on both sides of the mounting sleeve 25 are fixedly provided with sleeve tubes 26, and the inner wall of the sleeve tube 26 is slidably connected to a guide column 27, and the guide column 27 is fixedly connected to the stamping lower die 1. The upper surface of the stamping lower die 1 is fixedly connected to a limit bar 28, and the cross-sectional shape of the limit bar 28 is concave. A hook 29 is provided on one side of each sleeve tube 26, and both hooks 29 are fixedly connected to the sleeve die 24.

[0023] So that the factory crane lifting equipment can be used to hang it on the hook 29, the hook 29 is lifted, and the hook 29 drives the sleeve die 24 to move, which is convenient for the later transportation of the sleeve die 24. When in use, the mounting sleeve 25 is threadedly installed and locked with the output end of the punching electromechanical cylinder, and then the mobile phone vibrator raw material plate is placed on the inner wall of the limit bar 28, and the mounting sleeve 25 is pushed down by the punching electromechanical cylinder. The spring 23 pushes the stamping upper die 2 down, and the stamping upper die 2 drives multiple vibrator punching heads 22 to move down. The sleeve die 24 drives the sleeve tube 26 to slide down along the outer wall of the guide column 27. When the vibrator punching head 22 contacts the mobile phone vibrator raw material plate, the sleeve die 24 slides down along the outer wall of the multiple sliding columns 31, realizing multiple guided stamping and forming processes.

[0024] The use process of the stamping forming equipment of the mobile phone vibrator of the present invention is as follows: Step 1: Installation During stamping and forming, the material used for the mobile phone vibrator raw material plate is aluminum alloy precision die forgings, which has high strength and better durability. After determining the material used for the mobile phone vibrator raw material plate, the mounting sleeve 25 can be screwed and locked to the output end of the stamping cylinder. Then, the mobile phone vibrator raw material plate is placed on the inner wall of the limit bar 28. At the same time, the stamping lower die 1 can support the mobile phone vibrator raw material plate. Then the mounting sleeve 25 is pushed downward by the electric cylinder of the stamping machine, and the mounting sleeve 25 drives the spring 23 to move downward, and the spring 23 drives the stamping upper die 2 to move downward, and the stamping upper die 2 drives multiple vibrator punching heads 22 to move downward, and multiple vibrator punching heads 22 contact the mobile phone vibrator raw material plate. At the same time, the socket die 24 drives the socket tube 26 to slide down along the outer wall of the guide column 27. Multiple vibrator punching heads 22 can contact the mobile phone vibrator raw material plate to complete the stamping forming operation, and the socket die 24 slides down along the outer wall of multiple sliding columns 31. During the stamping forming contact, multiple vibrator punching heads 22 will generate a large vibration wave force.

[0025] Step 2: During positioning sensing, when the upper punching die 2 moves downward, it simultaneously drives the support block 14 downward, which in turn drives the pressing end 13 downward. The pressing end 13 presses against the sensing force of the positioning pressure sensor 12, indicating that the multiple vibrator punches 22 have begun to make contact with the mobile phone vibrator raw material sheet. Simultaneously, the vibrator punches 22 transmit pressure to the upper punching die 2, which in turn transmits pressure to the support block 14, which in turn transmits pressure to the support sleeve 15. The vibration sensor 16 on the support sleeve 15 can sense the vibration wave force value.

[0026] Step three, during static processing, the two socket blocks 3 are supported by the stamping lower die 1, the socket blocks 3 support the static electromagnet 11, the controller 30 supplies power to the static electromagnet 11, and the static electromagnet 11 generates an inclined magnetic attraction force on the magnetic attraction ramp 10, so that the static electromagnet 11 moves downward stably under the inclined magnetic attraction force, and avoids the stamping upper die 2 from moving upward and rebounding fluctuations. At the same time, the magnetic attraction ramp 10 drives the inclined groove 9 to generate an inclined suction force, and the inclined groove 9 can make the stamping upper die 2 generate an inclined suction force, so that the stamping upper die 2 is affected by the static inclined suction force of the static electromagnet 11, offsetting part of the rebound vibration force of the stamping upper die 2 that deviates upward and left and right.

[0027] Step 4: During dynamic processing, the controller 30 is used to start the contraction electric cylinder 21 at the same time. The contraction electric cylinder 21 drives the slide frame 20 to move downward and contract. The slide frame 20 drives the two slide rods 18 to move downward. At the same time, the slide rod 18 rotates along the arc path of the arc guide rail 19. The slide rod 18 drives the sleeve rod 17 to rotate. 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. The dynamic electromagnet 6 generates magnetic force after it is turned on. Since the adjacent surfaces of the dynamic electromagnet 6 and the permanent magnet 7 have the same magnetic poles, 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 to generate a repulsive force on the permanent magnet 7, the permanent magnet 7 can be squeezed to drive the inclined strip 8 to generate an inclined repulsive force. The inclined strip 8 generates an inclined repulsive force on the stamping upper die 2. In this way, the dynamic electromagnet 6 will continuously rotate to adjust the size of the inclined repulsive force, so that the repulsive force continues to increase to offset the rebound residual vibration force of the stamping upper die 2 upward and left and right deviations, until the vibration force sensed by the vibration sensor 16 is zero, then the vibration wave force of the multiple vibrator punch heads 22 in multiple directions on the stamping upper die 2 is accurately offset, ensuring that the multiple vibrator punch heads 22 on the stamping upper die 2 can stably stamp and form the mobile phone vibrator raw material plate.

In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the existing technology and are not described here.

[0029] While the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made to the present invention. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of the present invention.
