Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a multi-station stamping die for mobile phone casings. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] A search revealed prior art publication number CN219191001 U, which discloses a mobile phone case stamping die, specifically relating to the field of stamping die technology. The die includes a base, a support plate fixedly connected to one side of the top surface of the base, a movable seat on the top surface of the base, and connecting plates arranged parallel above the movable seat. The bottoms of both connecting plates are hinged to the top surface of the movable seat, and the tops of the two connecting plates are hinged to a movable plate. A driving component is provided on one side of the movable seat, and a limiting component is provided on the side of the movable plate near the support plate. A lower die is provided on the top surface of the movable plate, and a fixing component that is mirror-symmetrical about the lower die is provided on the top surface of the movable plate. This invention, by setting a driving component, drives the movable seat to move to the left. The movable seat causes the bottoms of the two connecting plates to rotate along the hinges, and the tops of the two connecting plates rotate along the hinges while simultaneously being pushed upwards by the limiting component, thereby causing the lower die to rise via the movable plate.

[0004] However, existing stamping dies typically cannot adjust the stamping speed of the cylinder according to the thickness of the metal sheet. This results in the stamping speed being too fast when stamping thicker metal sheets, causing uneven deformation or cracking of the metal sheet, leading to problems such as excessive local deformation and burrs, which affect the stamping quality. On the other hand, the stamping speed may be too slow when stamping thinner metal sheets, which not only increases production costs but also reduces production efficiency.

[0005] Therefore, based on the above search and combined with existing technology, a multi-station stamping die for mobile phone casing is proposed to solve the above problems. Utility Model Content

[0022] 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.

[0023] In one typical implementation of this application, please refer to Figures 1-4 As shown, a multi-station stamping die for a mobile phone casing includes: a base 1, four connecting rods 2 fixedly mounted on the top surface of the base 1, a same top plate 3 fixedly mounted on the top surface of the four connecting rods 2, a same upper die 4 slidably mounted on the four connecting rods 2, a lower die 5 fixedly mounted on the bottom surface of the upper die 4, and multiple stamping stations set on the lower die 5 to improve stamping efficiency; a cylinder 6 fixedly mounted on the top surface of the top plate 3, and the output shaft of the cylinder 6 passing through the side wall of the top plate 3 and connected to the top surface of the upper die 4.

[0024] The testing mechanism is set on the base 1 and is used to test the thickness of the metal plate.

[0025] The inspection mechanism includes: an L-shaped plate 7, a base 1 fixedly mounted on the side wall of the base 1, and a rectangular shell 8 fixedly mounted on the top surface of the L-shaped plate 7. Inside the rectangular shell 8, a laser metal thickness detector 20 is installed via a drive assembly. The laser metal thickness detector 20 scans the surface of the metal plate at a frequency of 50kHz, collecting five sets of data at each station (averaging the values ​​after removing the maximum / minimum values). The data is transmitted to the processor 23 in real time to calculate the thickness deviation value.

[0026] Based on the above features, metal plates in multiple stations on the lower mold 5 can be detected, and the stamping speed of the cylinder 6 can be adjusted according to the thickness of the same batch of metal plates. Specifically, by turning on the drive assembly, the laser metal thickness detector 20 is made to detect the metal in the lower mold 5 on the top surface of the lower mold 5. Then, the laser metal thickness detector 20 transmits the data to the processor 23, and the processor 23 transmits the processed data to the controller 22, so that it can adjust the stamping speed of the cylinder 6.

[0027] The drive assembly includes: a motor 12, which is fixedly mounted on the front side wall of a rectangular shell 8. A groove 9 is formed on the bottom surface inside the rectangular shell 8. A threaded rod 10 is rotatably connected to the inner wall of the groove 9. A slider 11 is threadedly connected to the threaded rod 10. The output shaft of the motor 12 is connected to the front side wall of the threaded rod 10. The drive assembly also includes: a connecting plate 13, which is fixedly mounted on the bottom surface of the slider 11. A groove 14 is formed on the top surface of the connecting plate 13. A threaded rod 15 is rotatably connected to the inner wall of the groove 14. A slider 16 is threadedly connected to the surface of the threaded rod 15. A motor 17 is fixedly mounted on the right side wall of the connecting plate 13. The output shaft of the motor 17 is connected to the right side wall of the threaded rod 15.

[0028] Based on the above features, the laser metal thickness detector 20 can be driven to move. When the laser metal thickness detector 20 needs to move back and forth, motor 12 is turned on, causing the threaded rod 10 to rotate, which in turn causes the slider 11 to move the connecting plate 13 and the L-shaped rod 18 in the connecting plate 13. When the L-shaped rod 18 moves, the fixed block 19 moves synchronously with the laser metal thickness detector 20. When the laser metal thickness detector 20 needs to move left and right, motor 17 is started, causing the threaded rod 15 to rotate, which causes the sliding block 16 to slide in the sliding groove 14, thus realizing the left and right movement of the laser metal thickness detector 20. The L-shaped rod 18 is fixedly installed on the top surface of the sliding block 16, and the fixed block 19 is fixedly installed on the left side wall of the L-shaped rod 18. The left side wall of the fixed block 19 is connected to the right side wall of the laser metal thickness detector 20, and the alarm 21 is fixedly installed on the top surface of the fixed block 19. When the laser metal thickness detector 20 detects that the thickness of one of the metal plates is inconsistent with the thickness of the other metal plates, the laser metal thickness detector 20 will stop above the metal plate and the alarm 21 will be activated to remind the staff to check whether the metal plate is not placed properly or does not meet the stamping thickness requirements of this batch.

[0029] The rectangular shell 8 has a controller 22 fixedly installed inside. The controller 22 (using Siemens S7-1200 PLC) has a processor 23 fixedly installed on one side of the controller 22.

[0030] The preset stamping parameters are shown in the table below:

[0031]

[0032] Working principle:

[0033] In operation, the operator places the metal plate on the lower mold 5, then starts the cylinder 6. The output shaft of the cylinder 6 drives the upper mold 4 to move downwards along the connecting rod 2, stamping the metal plate. Before stamping, the detection mechanism checks the thickness of the metal plate. Motor 12 starts, driving the threaded rod 10 to rotate, causing the slider 11 to move along the slide groove 9, thereby moving the connecting plate 13 and the L-shaped rod 18, adjusting the front-to-back position of the laser metal thickness detector 20. Motor 27 starts, driving the threaded rod 25 to rotate, causing the sliding block 16 to slide in the slide groove 14, adjusting the left-to-right position of the laser metal thickness detector 20. The laser metal thickness detector 20 detects the thickness of the metal plate on the upper mold 4 and transmits the data to the controller 22 and processor 23 for analysis, allowing the controller 22 to adjust the stamping speed of the cylinder 6. Furthermore, if the thickness of the metal plate is detected to be inconsistent with other plates, the laser metal thickness detector 20 stops above this metal plate, triggering the alarm 21 to remind the operator to check if the metal plate is improperly placed or does not meet the stamping thickness requirements.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
