[0031] 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.

[0032] The following describes an embodiment of this utility model based on its overall structure.

[0033] like Figures 1 to 5 As shown, this utility model provides an automatic part removal mechanism for precision stamping dies, including a bracket 1. A crossbar 2 is rotatably connected to the inner wall of one side of the bracket 1 via a deep groove ball bearing. A connecting frame 3 is fixedly provided at one end of the crossbar 2. A stamping die 4 is fixedly provided at the top of the connecting frame 3 via bolts. A flipping component 5 is provided on one side of the connecting frame 3. A cleaning component 6 is provided at the bottom of the connecting frame 3. The cleaning component 6 includes a protective cover 61, a reversing component 7, and a discharge component 8. The protective cover 61 is fixedly provided on the inner wall of the bottom of the bracket 1. A chip suction cylinder 62 is rotatably connected to the inner wall of one side of the protective cover 61 via a bearing. A plurality of equally spaced chip suction tubes 64 are fixedly provided on the surface of the chip suction cylinder 62. One end of the chip suction cylinder 62 penetrates the inner wall of one side of the protective cover 61 and is fixedly provided with a filter cylinder 65. An air pump 63 is fixedly provided on the surface of the filter cylinder 65.

[0034] In a further embodiment, the filter cylinder 65 is internally threaded with a sealing cap 66. A filter element is fixed to the inner wall of the filter cylinder 65 by screws. The filter element filters the sucked-in debris, preventing damage to the suction pump 63 due to debris intake. The filter element is exposed by separating the sealing cap 66, facilitating maintenance and replacement. A slag outlet 14 is provided on the surface of the protective cover 61. After the stamping die 4 rotates 180° around the crossbar 2, some debris remains attached to the inner wall of the stamping die 4. This debris is sucked in by the slag suction pipe 64, while some debris falls directly into the interior of the protective cover 61 due to its own gravity and slides along the inner wall of the protective cover 61. The slag outlet 14 and the slag storage box 16 are used to concentrate the debris, making it easier to clean up debris that falls directly into the interior of the protective cover 61 due to its own weight. A storage rack 15 is fixedly provided on the surface of the protective cover 61. The slag storage box 16 slides into the storage rack 15 to store the debris. The storage box 16 is slidably connected to the inner wall of the storage rack 15. The top of the interior of the slag storage box 16 is connected to the interior of the slag outlet 14. The suction end of the air pump 63 is connected to the interior of the filter cylinder 65 through a pipe so that the air pump 63 pumps out the gas inside the filter cylinder 65, causing a negative pressure to be formed inside the filter cylinder 65, thereby sucking up the debris attached to the inner wall of the stamping die 4.

[0035] In this embodiment, the flipping assembly 5 includes a flipping rod 51 and a support block 52. The flipping rod 51 is rotatably mounted on the inner wall of the other side of the bracket 1 via a deep groove ball bearing. The deep groove ball bearing can withstand large radial loads, improving the stability of the flipping rod 51. One end of the flipping rod 51 is fixedly connected to one side of the connecting frame 3, and the other end of the flipping rod 51 is provided with a flipping gear 53. The support block 52 is fixedly mounted on the other side of the bracket 1, and a flipping cylinder 54 is fixedly mounted on the back of the support block 52. A flipping rack 55 is fixedly mounted on the telescopic end of the flipping cylinder 54. The top end of the flipping rack 55 meshes with the bottom end of the flipping gear 53. A dovetail block 56 is fixedly mounted on the bottom end of the flipping gear 53. A groove 57 is opened at the top end of the support block 52 to slide against the surface of the flipping rack 55. An anti-detachment groove 58 is opened at the bottom end of the groove 57 to slide against the surface of the dovetail block 56. The anti-detachment groove 58 guides the movement of the flipping rack 55 through the dovetail block 56, improving the stability of the flipping rack 55 during movement. The tilting cylinder 54 is activated, extending and pushing the tilting rack 55 to move. The tilting rack 55, through the tilting gear 53 and the tilting rod 51, drives the connecting frame 3 to rotate a certain angle. Then, the telescopic end of the tilting cylinder 54 is controlled to shorten, realizing the reset of the connecting frame 3. Specifically, firstly, the tilting rack 55 drives the connecting frame 3 to rotate 90° through the tilting gear 53 and the tilting rod 51, so that the stamping die 4 can rotate 90° with the tilting rod 51. At this time, the opening of the stamping die 4 and the parting groove are aligned. After aligning with 81, the flip rack 55 drives the connecting frame 3 to rotate 90° again via the flip gear 53 and the flip rod 51, causing the opening of the stamping die 4 to face downwards and align with the openings of several chip suction pipes 64, so that the chip suction pipes 64 can clean the inner wall of the stamping die 4. After cleaning the stamping die 4, the telescopic end of the flip cylinder 54 is shortened, and the flip cylinder 54 drives the flip rack 55 to move 180° in the opposite direction, realizing the reset of the connecting frame 3 and the stamping die 4, so as to carry out the next feeding and stamping.

[0036] In this embodiment, the top of the bracket 1 has two sliding holes, and a stamping cylinder 9 is fixedly installed at the top of the bracket 1. A mounting plate 10 is fixedly installed at the telescopic end of the stamping cylinder 9. Two sliding rods that slide in relation to the sliding holes are fixedly installed at the top of the mounting plate 10. The sliding rods cooperate with the sliding holes to guide the lifting and lowering of the mounting plate 10. A stamping head 11 is fixedly installed at the bottom of the mounting plate 10. The stamping cylinder 9 pushes the stamping head 11 to move downward. The stamping head 11 cooperates with the stamping die 4 to achieve stamping. Support legs 12 are fixedly installed at the four corners of the bottom of the bracket 1. A baffle 13 is fixedly installed on one side of two of the support legs 12. The baffle 13 is used to install the directional motor 72.

[0037] In this embodiment, the directional assembly 7 includes a directional rod 71 and a directional motor 72. The directional rod 71 is rotatably mounted on the other side of the protective cover 61 via a bearing. One end of the directional rod 71 passes through the other side of the protective cover 61 and is placed inside the protective cover 61. One end of the directional rod 71 is fixedly connected to the other end of the chip suction cylinder 62. A directional gear 74 is fixedly mounted on the surface of the directional rod 71. A directional rack 75 is meshed with the bottom end of the directional gear 74. By pushing the directional rack 75, the directional gear 74 is driven to rotate. The directional gear 74 will drive the chip suction cylinder 62 to rotate through the directional rod 71, thereby causing the chip suction pipe 64 on the surface of the chip suction cylinder 62 to rotate at a certain angle with the directional rod 71 as the center. The opening of the chip suction pipe 64 no longer faces the inner wall of the top of the stamping die 4, but faces the inner wall of one side of the stamping die 4, thereby improving the cleaning effect of the chip suction pipe 64.

[0038] In this embodiment, a guide hole 76 is provided on the surface of the directional rack 75. A guide rod 77 is slidably connected to the inner wall of the guide hole 76. The guide hole 76 and the guide rod 77 cooperate to guide the movement of the directional rack 75, improving the stability of the directional rack 75 during movement. The contact portions of the two support legs 12 and the guide rod 77 are fixedly connected. The directional motor 72 is fixedly mounted on one side of the baffle 13. A three-lobe cam 73 is fixedly mounted on the drive shaft of the directional motor 72. Two pressure rods 78 are slidably connected to the surface of the three-lobe cam 73. One end of each pressure rod 78 is fixedly connected to one side of the directional rack 75. The directional motor 72 drives the three-lobe cam 73 to rotate. The surface of the three-lobe cam 73 always contacts the two pressure rods 78 when rotating. The three-lobe cam 73 applies force to the directional rack 75 through the two pressure rods 78, causing the directional rack 75 to reciprocate along the axis of the guide rod 77. The reciprocating directional rack 75 drives the directional rod 71 and the chip suction cylinder 62 to move through the directional gear 74. Specifically, the chip suction cylinder 62 will alternately rotate clockwise and counterclockwise with the directional rod 71 as the center, thereby realizing the swing of the chip suction pipe 64. The opening of the chip suction pipe 64 can not only face the inner wall of the top of the stamping die 4, but also face the inner walls on both sides of the stamping die 4, further improving the cleaning effect of the chip suction pipe 64.

[0039] In this embodiment, the delivery component 8 includes a delivery slot 81 and two push rod seats 84. The delivery slot 81 is formed on the surface of the protective cover 61. A translation frame 82 is slidably connected to the inner wall of the delivery slot 81. A plurality of equally spaced delivery rollers 83 are rotatably connected to the inner wall of the translation frame 82 via bearings. The delivery rollers 83 support the stamped part pushed out by the part-removing cylinder 17 and convert the sliding friction between the stamped part and the translation frame 82 into rolling friction, reducing resistance. Both push rod seats 84 are fixedly set on the surface of the protective cover 61. Electric push rods 85 are fixedly provided on the front of both push rod seats 84. Push plates 86 are fixedly provided on the telescopic ends of the two electric push rods 85. The top of the push plate 86... Both ends are fixedly connected to the bottom end of the translation frame 82. The surface of the push plate 86 is provided with a through groove 87. The inner wall of the through groove 87 is slidably connected to the guide plate 88. The back of the guide plate 88 is fixedly connected to the surface of the protective cover 61. The guide plate 88 guides the movement of the translation frame 82 through the through groove 87, improves the stability of the translation frame 82 when moving, and reduces the radial load on the telescopic end of the electric push rod 85. When a new size stamping die 4 is replaced, the electric push rod 85 drives the push plate 86 and the translation frame 82 to move a suitable distance so that the translation frame 82 can catch the stamped part pushed out by the part removal cylinder 17 after the stamping die 4 rotates 90° with the crossbar 2 as the center, thus increasing the applicable range.

[0040] In this embodiment, a part-removing cylinder 17 is embedded in the inner wall of the bottom end of the connecting frame 3. A lifting plate 18 is fixedly provided at the telescopic end of the part-removing cylinder 17. Part-removing rods 19 are fixedly provided at the four corners of the top of the lifting plate 18. Four through holes that slide with the surface of the part-removing rods 19 are opened on the inner wall of the top end of the connecting frame 3 and the bottom end of the stamping mold 4. Lifting grooves that slide with the surface of the lifting plate 18 are opened on the inner walls of both sides of the connecting frame 3. The lifting grooves guide the movement of the lifting plate 18. The telescopic end of the part-removing cylinder 17 extends and pushes the lifting plate 18 to move. The lifting plate 18 pushes the part-removing rods 19 to move. The part-removing rods 19 push out the stamped parts inside the stamping mold 4 to achieve demolding.

[0041] The tilting cylinder 54, the vacuum pump 63, the directional motor 72, the electric push rod 85, and the part-retrieving cylinder 17 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, a controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0042] Working principle and process of an automatic part removal mechanism for precision stamping dies:

[0043] After stamping, the tilting cylinder 54 is activated. The tilting cylinder 54 extends and pushes the tilting rack 55 to move. The tilting rack 55 drives the connecting frame 3 to rotate 90° around the crossbar 2 through the tilting gear 53 and the tilting rod 51. At this time, the opening of the stamping die 4 is aligned with the part ejection slot 81. Then, the part removal cylinder 17 is activated. The telescopic end of the part removal cylinder 17 extends and pushes the lifting plate 18 and the part removal rod 19 to move. The part removal rod 19 pushes out the stamped part inside the stamping die 4 to achieve demolding. The demolded stamped part falls into the top of the guide roller 83. The guide roller 83 supports the stamped part and converts the sliding friction between the stamped part and the translation frame 82 into rolling friction, reducing resistance. An external conveyor belt is set near the translation frame 82. Therefore, through the cooperation of the tilting component 5, the guide component 8, the part removal cylinder 17, the lifting plate 18 and the part removal rod 19, the stamped part can be pushed into the external conveyor belt while being ejected, realizing automatic material discharge and improving processing efficiency.

[0044] Then, the telescopic end of the control cylinder 17 is shortened, causing the lifting plate 18 to return to its original position, and the flipping cylinder 54 is restarted. The flipping cylinder 54 will extend and push the flipping rack 55 to move. The flipping rack 55 drives the connecting frame 3 to rotate 90° again through the flipping gear 53 and the flipping rod 51, causing the opening of the stamping die 4 to face downward and align with the openings of several chip suction pipes 64, so that the chip suction pipes 64 can clean the inner wall of the stamping die 4. At this time, the vacuum pump 63 is started, and the vacuum pump 63 will pump out the gas inside the filter cylinder 65, causing a negative pressure to be formed inside the filter cylinder 65. The filter cylinder 65 sucks up the debris attached to the inner wall of the stamping die 4 through the chip suction pipes 64, which solves the problem that the debris cannot be automatically cleaned from the inner wall of the stamping die 4 after the stamping part is ejected, which is beneficial to subsequent stamping. The debris is blocked by the filter element inside the filter cylinder 65. After multiple cleanings, the filter element is replaced by removing the sealing cover 66.

[0045] Furthermore, while starting the vacuum pump 63, the directional motor 72 is also started. The directional motor 72 drives the three-lobe cam 73 to rotate. The surface of the three-lobe cam 73 is always in contact with the two pressure rods 78 when rotating. The three-lobe cam 73 applies force to the directional rack 75 through the two pressure rods 78, causing the directional rack 75 to reciprocate along the axis of the guide rod 77. The reciprocating directional rack 75 drives the directional rod 71 and the chip suction cylinder 62 to move through the directional gear 74. Specifically, the chip suction cylinder 62 will alternately rotate clockwise and counterclockwise with the directional rod 71 as the center, thereby realizing the swing of the chip suction pipe 64. The opening of the chip suction pipe 64 can not only face the inner wall of the top of the stamping die 4, but also face the inner walls on both sides of the stamping die 4, further improving the cleaning effect of the chip suction pipe 64.

[0046] It should also be added that after cleaning the stamping die 4, the telescopic end of the control cylinder 54 is shortened, causing the cylinder 54 to drive the rack 55 to move 180° in the opposite direction, thereby resetting the connecting frame 3 and the stamping die 4 for the next feeding and stamping. During the process of the stamping die 4 rotating 180° around the crossbar 2, some debris still adheres to the inner wall of the stamping die 4. This debris is sucked in by the chip suction pipe 64, and some debris falls directly into the interior of the protective cover 61 due to its own weight, and slides along the inner wall of the protective cover 61 into the slag outlet 14 and the slag storage box 16, thereby concentrating this part of the debris and making it easier to clean the debris that falls directly into the interior of the protective cover 61 due to its own weight.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
