Description

Technical Field

[0001] This invention relates to the field of parts stamping technology, and in particular to a metal parts stamping equipment. Background Technology

[0002] Among the components of a mobile phone, the mid-plate is the main body, and other components are installed on the mid-plate. The mid-plate is also the carrier for fixing mobile phone components such as the screen, camera, and motherboard. In the existing technology, the mid-plate is usually processed and produced using punching equipment.

[0003] When processing and producing mobile phone mid-plates, existing punching equipment often requires multiple punching operations, each with a different shape. As a result, most factories need to use multiple punching machines to punch the mid-plates, leading to high production costs and low efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a metal part punching equipment that can solve the problem that existing factories often need to use multiple punching equipment to punch the mobile phone mid-plate when producing it, which results in high production costs and low efficiency.

[0005] The technical solution is as follows:

[0006] A metal punching and cutting device includes a worktable, a placement table, and a hydraulic cylinder. It also includes a rotating column, a punching die, a supporting die, a hole-filling die, an edge-filling die, a switching mechanism, a lifting mechanism, and a support mechanism. The punching die is detachably mounted on the rotating column, and the supporting die is detachably mounted on the placement table. The hole-filling die and the edge-filling die are slidably mounted on the placement table. The switching mechanism drives the rotating column to rotate, thereby rotating and switching the punching die. By switching different punching dies, different shapes of punching can be performed on the metal parts. The lifting mechanism drives the hole-filling die and the edge-filling die to rise and fall, allowing the hole-filling die and the edge-filling die to assist in punching the metal parts under different punching dies. The support mechanism supports the hole-filling die and the edge-filling die.

[0007] As an improvement to the above solution, the switching mechanism includes a connecting plate and a servo motor. The connecting plate is connected to the telescopic rod of the hydraulic cylinder, so that the hydraulic cylinder can drive the connecting plate to move up and down. The servo motor is connected to the connecting plate, and the rotating column is connected to the output shaft of the servo motor, so that the servo motor can drive the rotating column to rotate, and the servo motor and the rotating column can follow the connecting plate to move up and down.

[0008] As an improvement to the above solution, the switching mechanism further includes a magnetic block I, which is connected inside the rotating column, and the magnetic block I uses magnetic force to attract and fix the punching die.

[0009] As an improvement to the above solution, the lifting mechanism includes a connecting frame, pins, a push plate, and a support plate. Several connecting frames are detachably installed on the hole-filling mold and the edge-filling mold, and several pins are inserted into the hole-filling mold and the edge-filling mold, and several pins are also inserted into several connecting frames, so that the pins fix the hole-filling mold and the edge-filling mold on the connecting frames. The push plate and the support plate are both connected to the rotating column, so that the push plate and the support plate can rotate and lift synchronously with the rotating column. Moreover, through the cooperation of the push plate and the support plate with the connecting frame, the connecting frame, the hole-filling mold, and the edge-filling mold can lift and lower along with the push plate and the support plate.

[0010] As an improvement to the above solution, the support mechanism includes a fixed plate, a clamp, and a magnetic block II. The fixed plate is connected to the worktable, the clamp is slidably connected to the fixed plate, and the magnetic block II is connected to the connecting frame. The magnetic block II can magnetically attract the clamp.

[0011] As an improvement to the above solution, a fixing mechanism is also included. The fixing mechanism includes an air pump, a quick-release connector, and a connecting pipe. The air pump is connected to the workbench, the quick-release connector is detachably installed on the air pump, and the connecting pipe is connected to the quick-release connector and communicates with the support mold. This allows the air pump to extract air from the connecting pipe, thereby allowing the metal part to be adsorbed and fixed on the support mold.

[0012] As an improvement to the above solution, a positioning plate is also included, which is connected to the supporting mold and is used for positioning and placing metal parts.

[0013] As an improvement to the above solution, a fan is also included, which is connected to the fixed plate and is used to blow out the debris generated during the punching of the metal parts.

[0014] As an improvement to the above solution, a collection hopper is also included, which is connected to the worktable and can be used to collect and discharge the debris blown out by the fan.

[0015] As an improvement to the above solution, a shielding mechanism is also included, which includes an electric push rod and a shielding plate. The electric push rod is connected to the worktable, and the shielding plate is connected to the telescopic rod of the electric push rod. The shielding plate can be used to shield outward-splashing debris.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention mounts multiple different types of punching dies on a rotating column. The rotating column is then driven to rotate by a servo motor, allowing the different types of punching dies to be switched by rotation. Subsequently, the different types of punching dies are driven multiple times by a hydraulic cylinder to punch the metal parts, so that the metal parts are formed into the shape of a mobile phone mid-plate after multiple punchings. In this way, the metal part punching equipment can independently produce mobile phone mid-plates, which not only saves costs but also has high efficiency.

[0018] 2. By making the punching die, support die, hole-filling die, and edge-filling die all detachable, this invention allows for easy replacement of the punching die, support die, hole-filling die, and edge-filling die, thus facilitating the production of other types of mobile phone mid-plates.

[0019] 3. In this invention, after the metal part is placed on the support mold, the air between the metal part and the support mold is extracted by an air pump. This allows the metal part to be squeezed and pressed tightly against the support mold by the external air, thereby fixing the metal part and preventing the metal part on the support mold from shifting.

[0031] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0032] Example: A metal punching and cutting device, see below Figures 1-8As shown, the system includes a workbench 1, a placement platform 2, and a hydraulic cylinder 3. The workbench 1 consists of a tabletop and legs, with the two legs connected to the left and right sides of the bottom of the tabletop. The placement platform 2 is connected to the top of the tabletop of the workbench 1. The hydraulic cylinder 3 is connected to the top of the tabletop of the workbench 1. The system also includes rotating columns 4, punching dies 5, support dies 6, hole-filling dies 7, edge-filling dies 8, a switching mechanism, a lifting mechanism, and a support mechanism. Both rotating columns 4 have round holes on their outer surfaces. Several punching dies 5 are detachably mounted on the two rotating columns 4, and all punching dies 5 are installed at the round holes of the rotating columns 4. The support dies 6 are detachably mounted on the placement platform 2. The above-mentioned components are as follows: Hole-filling mold 7 is slidably mounted on the placement table 2, and hole-filling mold 7 is detachably mounted; Edge-filling mold 8 is slidably mounted on the placement table 2, and edge-filling mold 8 is detachably mounted; The switching mechanism is used to drive the rotating column 4 to rotate, thereby driving the punching mold 5 to rotate and switch. By switching different punching molds 5, different shapes of punching can be performed on the metal parts; The lifting mechanism is used to drive the hole-filling mold 7 and the edge-filling mold 8 to lift and lower, so that the hole-filling mold 7 and the edge-filling mold 8 can assist the metal parts to be punched under different punching molds 5 through lifting and lowering; The support mechanism is used to support the hole-filling mold 7 and the edge-filling mold 8.

[0033] See Figure 4 As shown, the switching mechanism includes a connecting plate 9, a servo motor 10, and a magnetic block I 11. The connecting plate 9 is connected to the telescopic rod of the hydraulic cylinder 3, enabling the hydraulic cylinder 3 to drive the connecting plate 9 to rise and fall. Both servo motors 10 are connected to the connecting plate 9, and the two rotating columns 4 are respectively connected to the output shafts of the two servo motors 10, enabling the servo motors 10 to drive the rotating columns 4 to rotate and rise and fall through the connecting plate 9, thus enabling the servo motors 10 and the rotating columns 4 to follow the connecting plate 9 in rising and falling. The magnetic block I 11 is connected to the circular hole of the rotating column 4, and the punching die 5 is made of iron, so that the magnetic block I 11 can attract and fix the punching die 5 through magnetic force.

[0034] See Figure 5 , Figure 6 and Figure 7As shown, the lifting mechanism includes a connecting frame 13, a pin 14, a push plate 15, and a support plate 16. The connecting frame 13 is detachably installed on the lower side of both the hole-filling mold 7 and the edge-filling mold 8. Pins 14 are inserted between the lower side of the hole-filling mold 7 and the edge-filling mold 8 and the connecting frame 13, and the pins 14 can fix the hole-filling mold 7 and the edge-filling mold 8 on the connecting frame 13. The push plate 15 is connected to the rotating column 4, so that the push plate 15 can rotate and lift synchronously with the rotating column 4, and the push plate 15 can contact the connecting frame 13 through rotation. The support plate 16 is connected to the rotating column 4, so that the support plate 16 can rotate and lift synchronously with the rotating column 4, and the support plate 16 can contact the connecting frame 13 through rotation, so that the push plate 15 and the support plate 16 can clamp the connecting frame 13. Then, the push plate 15 and the support plate 16 can lift and lower along with the rotating column 4, which can drive the connecting frame 13, the hole-filling mold 7, and the edge-filling mold 8 to lift and lower.

[0035] See Figure 6 , Figure 7 and Figure 8 As shown, the support mechanism includes a fixed plate 17, a clamp 18, and a magnetic block II 19. The fixed plate 17 is connected to the tabletop of the workbench 1, and has several elliptical holes. The clamp 18 is slidably connected to the upper side of the fixed plate 17, and clamps the connecting frame 13, so that the clamp 18 supports the connecting frame 13, the hole-filling mold 7, and the edge-filling mold 8. The push plate 15 can contact the clamp 18 by rotation, so that the push plate 15 can push the clamp 18 to move backward, thereby releasing the clamp 18 from the connecting frame 13. The magnetic block II 19 is connected inside the connecting frame 13, and the clamp 18 is made of iron, so that the magnetic block II 19 can hold the clamp 18 by magnetic force.

[0036] In use, the metal part is placed on the support mold 6. Then, the hydraulic cylinder 3 drives the connecting plate 9, servo motor 10, rotating column 4, and punching die 5 to move downward, so that the punching die 5 punches the metal part on the support mold 6, thereby punching the metal part on the support mold 6 to the required size. After the metal part on the support mold 6 is punched, the hydraulic cylinder 3 drives the connecting plate 9, servo motor 10, rotating column 4, and punching die 5 to move upward and reset. Then, the servo motor 10 drives the rotating column 4 to rotate, thereby driving the punching die 5, push plate 15, and support plate 16 to rotate, thereby switching other punching dies 5 to the bottom of the rotating column 4 by rotation. When the push plate 15 contacts the clamp 18 by rotation, the push plate 15 will squeeze the clamp 18. 8 moves backward, separating the clip 18 from the magnetic block II 19, thereby releasing the clip 18 from the connecting frame 13. The push plate 15 then adheres tightly to the top of the connecting frame 13. Simultaneously, when the support plate 16 rotates and contacts the connecting frame 13, the support plate 16 supports the connecting frame 13. At this time, the push plate 15 and the support plate 16 clamp and limit the connecting frame 13. Then, the hydraulic cylinder 3 drives the connecting plate 9, servo motor 10, rotating column 4, and punching die 5 downward again, causing the other punching dies 5 switched to the bottom of the rotating column 4 to punch the metal parts on the support die 6. Simultaneously, the downward movement of the rotating column 4 drives the push plate 15 and support plate 16 downward, causing the push plate 15 and support plate 16 to drive the connecting frame 13 and pin 14 downward. This causes the hole-filling mold 7 to move downwards, allowing the edge-filling mold 8 to continue providing edge-filling support to the metal parts on the support mold 6. This ensures that after the metal parts on the support mold 6 are punched by other punching molds 5, the required holes can be punched out. After the metal parts on the support mold 6 have finished punching, the hydraulic cylinder 3 drives the connecting plate 9, servo motor 10, rotating column 4, and punching mold 5 to move upwards and reset. This causes the rotating column 4 to drive the push plate 15 and support plate 16 to move upwards and reset, which in turn drives the connecting frame 13 and pin 14 to move upwards and reset, thereby causing the hole-filling mold 7 to move upwards and reset. The above operation is then repeated, and the other punching molds 5 are switched to the bottom of the rotating column 4 by rotation. When the push plate 15 passes through... When the clamp 18 is separated from the rotating part, the clamp 18 will move forward and reset under the magnetic attraction of the magnetic block II 19, so that the clamp 18 contacts the magnetic block II 19, thereby clamping the connecting frame 13. The push plate 15 will then leave the top of the connecting frame 13. When the support plate 16 is separated from the connecting frame 13 by rotation, the push plate 15 and the support plate 16 will release the clamping limit on the connecting frame 13. Then, the hydraulic cylinder 3 will drive the connecting plate 9, the servo motor 10, the rotating column 4 and the punching die 5 to move downward again, so that the other punching dies 5 switched to the bottom of the rotating column 4 will punch the metal parts on the support die 6. At this time, the downward movement of the rotating column 4 will drive the push plate 15, the support plate 16, the connecting frame 13, the pin 14 and the edge-forming die 8 to move downward.The filling die 7 continues to support the metal part on the supporting die 6, allowing the edges of the metal part to bend after being punched by other punching dies 5, thus forming the shape of a mobile phone mid-plate. After the metal part on the supporting die 6 has been punched, the hydraulic cylinder 3 drives the connecting plate 9, servo motor 10, rotating column 4, and punching die 5 to move upward and reset. The rotating column 4 then drives the push plate 15, supporting plate 16, connecting bracket 13, pin 14, and edge filling die 8 to move upward and reset. Finally, the metal part forming the shape of a mobile phone mid-plate is removed from the supporting die 6. When it is necessary to replace the punching die 5 to create other styles of mobile phone mid-plates, the punching die 5 can be removed from the rotating column 4. This process separates the punching die 5 from the magnetic block I11. Then, other types of punching dies 5 are placed back in their original positions, bringing them into contact with the magnetic block I11. The magnetic block I11 then magnetically attracts and fixes the other types of punching dies 5. When it is necessary to replace the support die 6, the hole-filling die 7, and the edge-filling die 8 to create other types of mobile phone mid-plates, the pin 14 can be pulled forward. Then, the support die 6, the hole-filling die 7, and the edge-filling die 8 are pulled upwards from the placement table 2. The other types of support dies 6, the hole-filling die 7, and the edge-filling die 8 are then placed back in their original positions, and the pin 14 is inserted backwards again, fixing the hole-filling die 7 and the edge-filling die 8 onto the connecting bracket 13.

[0037] See Figure 9 As shown, it also includes a fixing mechanism, which includes an air pump 20, a quick-release connector 21, and a connecting pipe 22. The air pump 20 is connected to the tabletop of the workbench 1. The quick-release connector 21 is detachably installed at the air outlet of the air pump 20. The connecting pipe 22 is connected to the quick-release connector 21 and is connected to the support mold 6, so that the air pump 20 can draw out the air in the connecting pipe 22, thereby allowing the metal parts to be adsorbed onto the support mold 6 for fixing.

[0038] After the metal part is placed on the support mold 6, the air pump 20 can be used to extract the air between the metal part and the support mold 6 through the connecting pipe 22, so that the metal part is pressed tightly against the support mold 6 by the external air. In this way, the metal part on the support mold 6 can be fixed to prevent the metal part from shifting. When it is necessary to remove the metal part that forms the middle plate of the mobile phone from the support mold 6, the air pump 20 can be used to blow air slightly between the metal part and the support mold 6 through the connecting pipe 22, so that the metal part that forms the middle plate of the mobile phone is not tightly attached to the support mold 6, thus making it easier to remove the metal part that forms the middle plate of the mobile phone. Afterwards, when it is necessary to replace the support mold 6, the quick-release connector 21 can be removed from the air pump 20 first, and then the quick-release connector 21 and the connecting pipe 22 can be replaced together when replacing the support mold 6.

[0039] See Figure 9 As shown, it also includes a positioning plate 23, which is connected to the support mold 6. The positioning plate 23 is used for positioning and placing metal parts. By setting the positioning plate 23, when it is necessary to place metal parts on the support mold 6, the positioning plate 23 can be used for positioning assistance.

[0040] See Figure 10 As shown, it also includes a fan 24, which is connected to the fixed plate 17. The fan 24 can blow air out through the elliptical hole of the fixed plate 17 to blow out the debris generated by the punching of the metal parts. By setting the fan 24, the debris generated by the punching of the metal parts can be blown forward from the support mold 6 and the placement table 2 to prevent the debris from affecting the punching of the metal parts.

[0041] See Figure 10 As shown, it also includes a collection hopper 25, which is connected between the left and right sides of the workbench 1. A certain gap is left between the collection hopper 25 and the front end of the workbench 1, so that after the debris is blocked by the collection hopper 25, it can fall down into the collection hopper 25 through the gap. This allows the collection hopper 25 to collect and drop the debris blown out by the fan 24. By setting up the collection hopper 25, after the fan 24 blows the debris forward from the support mold 6 and the placement platform 2, the debris can fall down through the obstruction of the collection hopper 25 and be collected and dropped down by the collection hopper 25, so that people can clean up the debris and prevent it from scattering all over the ground.

[0042] See Figure 10 As shown, it also includes a shielding mechanism, which includes an electric push rod 26 and a shielding plate 27; both electric push rods 26 are connected to the table of the workbench 1, and the shielding plate 27 is connected between the telescopic rods of the electric push rods 26. The shielding plate 27 can be used to shield outward flying debris.

[0043] After the metal part is placed on the support mold 6, the baffle 27 can be moved upward by the electric push rod 26 to block the flying debris and prevent it from causing injury to the human body. When it is necessary to remove the metal part that forms the shape of the mobile phone midplate from the support mold 6, the baffle 27 is first moved downward to reset by the electric push rod 26, and then the metal part that forms the shape of the mobile phone midplate can be removed from the support mold 6.
