Description

Technical Field

[0001] This invention relates to the field of punching die technology, and more specifically, to a conductive sheet punching die and its forming process. Background Technology

[0002] A conductive sheet punching die is a type of mold used to manufacture conductive sheets, which are components used in electronic devices to transmit current or signals. The function of this die is to punch conductive materials into conductive sheets of a specific shape to meet the needs of electronic devices.

[0003] Among the published documents, Chinese Patent Publication No. CN211101047U discloses a precision punching die for parts. This punching die has a punching head fixedly installed inside a circular groove. When it is necessary to punch conductive sheets of different sizes for mobile phones, the processing can be carried out by adjusting the distance between two sets of movable blocks in the lower die and replacing the punching head in the upper die. This not only saves the time of changing the die, but also reduces the processing cost. However, this punching die has the following problems.

[0004] When a punching die is used to punch and form a conductive sheet, although the downward punching force is a specified force to achieve punching, wear will occur when the punching tool comes into contact with the conductive sheet during the punching process. It is difficult to detect uneven force in time and repair the punching die in time. The problem of needing to repair the punching die is only discovered when a large number of damaged conductive sheets are produced. Therefore, it is difficult to know in time whether the punching die needs to be repaired. To address this issue, a conductive sheet punching die and its forming process are provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a conductive sheet punching die and its forming process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conductive sheet punching die, including a lower punching die, wherein a sleeve positioning block is fixedly connected at each of the four corners of the outer wall of the lower punching die, and a linkage detection mechanism is installed on the inner wall of the sleeve positioning block;

[0007] The linkage detection mechanism includes a sensing extrusion column installed on the inner wall of the sleeve positioning block. A fixed guide ring for guiding the sensing extrusion column is fixedly connected to the bottom end of the sleeve positioning block. A tension spring and a linkage pull ring are arranged sequentially from top to bottom below the fixed guide ring. A linkage collar frame is fixedly connected to the bottom end of the sensing extrusion column. An extrusion support column is welded to the bottom end of the linkage collar frame near its middle position. A pressure sensor is fixedly connected to the lower punching die at the bottom end of the extrusion support column. An upper punching die is installed above the lower punching die.

[0008] A sensing and detection component is provided on one side of the upper punching die;

[0009] A calibration alarm component is installed at the top of the upper punching die. The sensing extrusion column and the sleeve positioning block are slidably connected. The outer wall of the sensing extrusion column and the inner wall of the sleeve positioning block are both polished. The tension spring is fixedly connected to the fixed guide ring and the linkage pull ring respectively. The inner wall of the linkage pull ring is welded to the outer wall of the sensing extrusion column. A linkage slider is fixedly connected to one side of the outer wall of the linkage pull ring. The linkage slider is vertically slidably connected to the lower punching die. Guide pillars are installed inside the linkage collar frame and on both sides of the extrusion pillar. Both guide pillars are vertically slidably connected to the extrusion pillar. A conductive sheet punching cutter is fixedly connected to the top of the lower punching die near its middle position.

[0010] Using the above technical solution, the upper punching die moves downward, causing the first and second positioning extrusion protrusions to move downward. The sensing extrusion column moves downward along the internal guide of the sleeve positioning block. The sensing extrusion column drives the linkage pull ring to move downward. The tension spring drives the fixed guide ring to move downward. The linkage pull ring drives the linkage slider to move downward along the outer wall of the lower punching die. The extrusion column presses against the sensing top of the pressure sensor. The pressure sensor can sense the specific pressure of the upper and lower punching dies after they are closed. The pressure value between the lower and upper punching dies changes, and there is wear between the lower and upper punching dies, requiring timely maintenance.

[0011] Preferably, the sensing and detection assembly includes a first positioning and extrusion protrusion disposed on one side of the upper punching die, and a conductive sheet punching upper cutting tool is fixedly connected to the bottom end of the upper punching die near its middle position. Two guide posts are slidably connected inside the upper punching die near its other side. A lateral distance sensor is fixedly connected to one side of the outer wall of the first positioning and extrusion protrusion, and a vertical distance sensor for vertical distance sensing is fixedly connected in front of the lateral distance sensor. A lateral sensing block is installed at the output end of the lateral distance sensor. A second positioning and extrusion protrusion fixedly connected to the upper punching die is provided on one side of the lateral sensing block, and the lateral sensing block and the second positioning and extrusion protrusion are fixedly connected. A vertical sensing block is installed below the vertical distance sensor, and a fixed support block is fixedly connected to the sleeve positioning block on the outer wall of the vertical sensing block. The top of the lateral distance sensor and the top of the lateral sensing block are on the same horizontal line, and the vertical sensing block and the fixed support block are welded together.

[0012] Using the above technical solution, after the upper punching die moves the first positioning extrusion protrusion downward, the lower punching die and the upper punching die are pressed together to the specified pressure value. When the distance sensed between the lateral distance sensor and the lateral sensing block changes, it is determined that the force on the left and right sides of the upper punching die is uneven. In this case, the upper punching die and the lower punching die need to be repaired. The two vertical distance sensors sense the two vertical sensing blocks respectively. If the sensed distances are not the same, the upper punching die and the lower punching die are in a damaged state.

[0013] Preferably, the calibration alarm component includes a stamping support rod fixedly installed on the top of the upper punching die;

[0014] A pressure sensor for pressure sensing is fixedly installed at the top of the stamping support rod. A pressing cylinder is fixedly connected to the top of the pressing pressure sensor. The outer wall of the output end of the pressing cylinder is provided with a sleeve concave plate fixedly connected to the lower punching die. A controller is fixedly installed on one side of the sleeve concave plate. A display screen is fixedly connected to one side of the controller. An alarm light and a buzzer are arranged sequentially from left to right at the top of the display screen. A wireless remote transceiver is fixedly connected to one side of the controller and near the buzzer. The pressing cylinder is fixedly connected to the sleeve concave plate. The alarm light and the buzzer are both communicatively connected to the output end of the display screen.

[0015] Using the above technical solution, the alarm light is activated via the display screen, and a buzzer sounds an alarm. The wireless remote transceiver remotely transmits the fault information of the conductive sheet punching die damage to the back-end administrator's computer, enabling remote management.

[0016] A conductive sheet punching and forming process, the method includes the following steps:

[0017] Step 1: First, when stamping, the conductive sheet profile is placed on the upper surface of the conductive sheet punching tool and formed into a conductive sheet by stamping.

[0018] Step 2: Secondly, when the present invention performs pressure calibration, it uses a linkage detection mechanism to sense whether the edge of the punching die is within the specified pressure range for stamping.

[0019] Step 3: Then, when the present invention performs sensor calibration, it uses a sensor detection component to detect whether the upper punching die and the lower punching die maintain a specified distance for sensing forming.

[0020] Step 4: When the alarm is triggered, if any data is different from the data set on the lateral distance sensor, it is determined that the punching die is damaged and an alarm will be triggered immediately.

[0021] The technical effects and advantages of this invention are as follows:

[0022] 1. The present invention employs a linkage detection mechanism to press down the first positioning extrusion protrusion and the second positioning extrusion protrusion on the two sensing extrusion columns respectively. The linkage pull ring drives the tension spring to stretch downward, and at the same time, the tension spring drives the fixed guide ring to move downward. The linkage collar frame moves downward along the outer wall of the two guide pillars. The pressure sensor can sense the specific pressure of the pressure around the upper and lower punching dies after they are closed. When the pressure value of the pressure sensor is different from the distance set by the punching pressure sensor, it is determined that the punching die is damaged and needs to be repaired in time. The present invention can promptly know that the punching die needs to be repaired.

[0023] 2. This invention uses a sensing and detection component to press the lower and upper punching dies together to a specified pressure value. A lateral distance sensor senses the position of the lateral sensing block. When the distance sensed between the lateral distance sensor and the lateral sensing block changes, it is determined that the punching die needs maintenance. Two vertical distance sensors sense the two vertical sensing blocks respectively. If the sensed distances are not the same, it is determined that the punching die needs maintenance. This allows for timely detection of whether the punching die needs maintenance, avoiding the continuous use of damaged punching dies to process conductive sheets.

[0024] 3. In this invention, the conductive sheet profile is placed on the upper surface of the conductive sheet punching cutter by calibrating the alarm component. The output end of the pressing cylinder drives the punching pressure sensor to move downward. The punching pressure sensor drives the punching support rod to move downward. The punching support rod drives the upper punching die to move downward along the outer wall of the two guide pillars. The punching pressure sensor can sense the output pressure. The pressure sensed by the punching pressure sensor is compared with the pressure sensed by the pressure sensor. If they are different, it is known that the punching die is damaged, and the alarm light is activated to sound an alarm. At the same time, the buzzer sounds an alarm to indicate that the punching die is damaged. This allows for timely detection of the damage to the punching die.

[0025] Through the interaction of the above multiple functions, firstly, the pressure value of the pressure sensor is compared with the distance set by the punching force sensor. Then, the two vertical distance sensors respectively sense and compare the two vertical sensing blocks. Finally, the two vertical distance sensors respectively sense the two vertical sensing blocks. In summary, it is possible to know in time whether the punching die needs maintenance, avoid the damaged punching die from continuously punching the conductive sheet, and ensure that the punching die punches the conductive sheet in an undamaged state.

The upper punching die 13 drives the conductive sheet punching cutter 14 to move downward and punch at the top position of the conductive sheet profile. After the upper punching die 13 and the conductive sheet punching cutter 12 are attached, stamping is achieved.

[0039] In some embodiments, as shown in the appendix Figure 1-5As shown, the sensing and detection assembly includes a first positioning extrusion protrusion 16 disposed on one side of the upper punching die 13, and a conductive sheet punching upper blade 14 fixedly connected to the bottom end of the upper punching die 13 near its middle position.

The horizontal sensing block 19 and the second positioning extrusion protrusion 20 are fixedly connected. A vertical sensing block 21 is installed below the vertical distance sensor 18. A fixed support block 22 is provided on the outer wall of the vertical sensing block 21 and is fixedly connected to the sleeve positioning block 2. The top of the horizontal distance sensor 17 and the top of the horizontal sensing block 19 are on the same horizontal line. The vertical sensing block 21 and the fixed support block 22 are welded together.

[0040] In some embodiments, as shown in the appendix Figure 4-6 As shown, the calibration alarm assembly includes a stamping support rod 23 fixedly installed on the top of the upper punching die 13;

[0041] A pressure sensor 24 for pressure sensing is fixedly installed at the top of the stamping support rod 23. A pressing cylinder 25 is fixedly connected to the top of the pressing sensor 24. A sleeve concave plate 26 fixedly connected to the lower punching die 1 is provided on the outer wall of the output end of the pressing cylinder 25. A controller 27 is fixedly installed on one side of the sleeve concave plate 26. A display screen 28 is fixedly connected to one side of the controller 27. An alarm light 29 and a buzzer 30 are arranged sequentially from left to right at the top of the display screen 28. A wireless remote transceiver 31 is fixedly connected to one side of the controller 27 and near the buzzer 30. The pressing cylinder 25 is fixedly connected to the sleeve concave plate 26. The alarm light 29 and the buzzer 30 are both connected to the output end of the display screen 28.

[0042] The principle of the conductive sheet punching die of the present invention during implementation is as follows:

[0043] Firstly, when the present invention performs stamping, the conductive sheet profile is placed on the upper surface of the conductive sheet punching cutter 12. The controller 27 starts the output end of the pressing cylinder 25 to move downward along the inner guide of the sleeve concave plate 26. At the same time, the output end of the pressing cylinder 25 drives the punching pressure sensor 24 to move downward. The punching pressure sensor 24 drives the punching support rod 23 to move downward. The punching support rod 23 drives the upper punching die 13 to move downward along the outer wall of the two guide pillars 15. At the same time, the upper punching die 13 drives the conductive sheet punching cutter 14 to move downward to punch and form the conductive sheet profile at the top position.

[0044] Secondly, during pressure calibration, the upper punching die 13 drives the first positioning extrusion protrusion 16 and the second positioning extrusion protrusion 20 downwards. The first positioning extrusion protrusion 16 and the second positioning extrusion protrusion 20 respectively press down on the two sensing extrusion pillars 3. The sensing extrusion pillars 3 move downwards along the internal guide of the sleeve positioning block 2. At the same time, the sensing extrusion pillars 3 drive the linkage pull ring 6 downwards. The linkage pull ring 6 drives the tension spring 5 downwards. At the same time, the tension spring 5 drives the fixed guide ring 4 downwards. The linkage pull ring 6 drives the linkage slider 7 to move downwards along the outer wall of the lower punching die 1. The linkage collar frame 8 moves downwards along the outer wall of the two guide pillars 11. At the same time, the linkage collar... The frame 8 drives the extrusion support 9 to move downwards. The extrusion support 9 presses against the sensing top of the pressure sensor 10. The pressure sensor 10 can sense the specific pressure of the upper punching die 13 and the lower punching die 1 after they are closed. When the pressure value of the pressure sensor 10 is the same as the distance set by the punching pressure sensor 24, it is determined that the lower punching die 1 and the upper punching die 13 are not worn or damaged, and the specified pressure is maintained for punching. When the pressure value between the lower punching die 1 and the upper punching die 13 changes, it is determined that the punching pressure between the lower punching die 1 and the upper punching die 13 is uneven, and there is a wear problem between the lower punching die 1 and the upper punching die 13, which needs to be repaired in time.

[0045] Then, during the sensor calibration of this invention, after the upper punching die 13 moves the first positioning extrusion protrusion 16 downward, the lower punching die 1 and the upper punching die 13 are pressed together to a specified pressure value. The first positioning extrusion protrusion 16 supports the lateral distance sensor 17, which senses the distance to the lateral sensing block 19. At the same time, the second positioning extrusion protrusion 20 supports the lateral sensing block 19. When the sensed distance between the lateral distance sensor 17 and the lateral sensing block 19 changes, it is determined that the upper punching die 13 is not properly positioned. Uneven force on the left and right sides of the mold 13 causes the upper punching mold 13 to tilt. This means that the upper punching mold 13 and the lower punching mold 1 need to be repaired. If the distance is consistent, it is determined that the upper punching mold 13 and the lower punching mold 1 are not damaged. At the same time, the two vertical distance sensors 18 sense the two vertical sensing blocks 21 respectively. If the sensed distances are the same, the upper punching mold 13 and the lower punching mold 1 are not damaged. If the sensed distances are different, the upper punching mold 13 and the lower punching mold 1 are damaged and need to be repaired in time.

[0046] When the final alarm is triggered, if the conductive sheet punching die is determined to be damaged, the alarm light 29 will be activated via the display screen 28, and the buzzer 30 will sound an alarm. The alarm problem will also be displayed on the display screen 28. The wireless remote transceiver 31 will remotely transmit the conductive sheet punching die damage fault to the back-end administrator's computer, enabling remote management. This allows for timely notification of whether the conductive sheet punching die is damaged and requires repair. If so, repair can be carried out immediately to prevent the conductive sheet punching die from continuing to punch even when damaged, which could result in a large amount of conductive sheet breakage.

[0047] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
