Description

Technical Field

[0002] As a key piece of equipment in industrial production, stamping dies are widely used to process raw materials such as metal sheets into various-shaped stamping parts. In stamping operations, the support structure of stamping parts is an important factor affecting production quality and efficiency as well as the service life of the die.

[0003] In common stamping dies of the prior art, the lower die is usually directly fixedly installed on the support base. This design results in the necessity of arranging an ejection structure inside the die cavity during demoulding. And in order to limit the ejector rod, grooves need to be cut inside the cavity. In this way, during the demoulding process, the ejector rod is extremely likely to damage the surface of the stamping part, and during stamping, groove marks will also be left on the surface of the stamping part, greatly reducing the product quality.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a stamping part support structure for a stamping die, which has the following beneficial effects:

[0020] 1. The stamping parts support structure used for the stamping die, after the stamping is completed, the upper die rises to drive the positioning block to move upward, the positioning block interacts with the convex block to make the positioning column disengage from the positioning groove, triggering the touch switch to start the servo motor, and driving the lower die to flip 180 degrees. At the same time, the gear ring and the abutment component cooperate with each other to generate vibration. This combination of flipping and vibration can more efficiently demould the formed sheet metal parts. Compared with the traditional demoulding method relying on the ejector rod, it avoids the damage of the ejector rod to the surface of the sheet metal parts, and will not leave groove marks on the surface of the sheet metal parts, which greatly guarantees the production quality of the sheet metal parts, reduces the scrap rate, and improves the production efficiency.

[0021] 2. The stamping part support structure used for the stamping die, during the stamping process, the upper die moves downward to drive the driving column and the positioning block to move downward, the positioning block pushes the protrusion to keep the sliding column and the positioning column stable, the positioning column is firmly inserted in the positioning groove to ensure that the lower die does not rotate, providing a stable support foundation for the stamping operation, avoiding the shape deviation of the stamping part caused by the shaking of the lower die, effectively improving the stability of the stamping process, and thus improving the forming accuracy of the stamping part.

[0022] 3. The stamping part support structure for the stamping die, through the seal cavity, spring, air inlet pipe and air outlet pipe structures arranged in the positioning and starting component, after the seal disc moves leftward to discharge the air in the seal cavity, due to the small diameter of the air inlet pipe, the external air slowly enters, making the seal disc can only reset slowly, preventing the seal disc from quickly resetting due to the elasticity of the spring, avoiding the positioning column quickly inserting into the positioning groove and causing the first rotating shaft to be unable to rotate, thereby protecting the servo motor, effectively avoiding damage to the servo motor, extending the service life of the equipment, and reducing the equipment maintenance cost.

Specific implementation manner

[0034] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-10 , a stamping part support structure for a stamping die, including a base 1 and an upper die 3 longitudinally movably installed directly above the base 1 through a cylinder. A movable slot 2 is penetrated and opened at the center of the surface of the base 1. A lower die 4 is rotatably connected inside the movable slot 2. A positioning and starting component 5 and a flipping and vibrating component 6 are respectively installed on both sides of the lower die 4 inside the base 1. The output ends of the positioning and starting component 5 and the flipping and vibrating component 6 are fixedly connected to the center of the side surface of the lower die 4. Cavities matching the upper die 3 are provided at both the top and the bottom of the lower die 4.

[0036] In this implementation manner, the lower die 4 is rotatably connected in the movable slot 2. The positioning and starting component 5 and the flipping and vibrating component 6 respectively play the roles of positioning, starting flipping, and vibrating demoulding for the lower die 4. Compared with the traditional method of fixing the lower die 4, it has obvious advantages in terms of demoulding and stamping accuracy.

[0037] Specifically, the positioning and starting component 5 includes a left fixed seat 51 fixedly connected inside the base 1. A chute 52 is formed inside the left fixed seat 51. A touch switch 53 is fixedly installed inside the left fixed seat 51. The output end of the touch switch 53 extends into the chute 52. A fixed rod 54 is fixedly connected to the inner wall of the chute 52. A sliding column 55 is slidably connected to the outer surface of the fixed rod 54. A convex block 56 is rotatably connected to the top end of the side surface of the sliding column 55. A driving column 57 is longitudinally slidably connected inside the left fixed seat 51. The top of the driving column 57 is fixedly connected to the bottom of the upper die 3. A positioning block 58 is fixedly connected to the surface of the driving column 57 close to the convex block 56. A sealing cavity 518 is formed inside the left fixed seat 51. A sealing disc 513 is fixedly connected to the end of the sliding column 55 away from the convex block 56. A spring 59 is movably installed inside the sealing cavity 518. A bearing one 510 is fixedly installed inside the left fixed seat 51. The inner ring of the bearing one 510 is fixedly connected to a rotating shaft one 511. A positioning groove 512 is formed at the center of the surface of the rotating shaft one 511 close to the sealing disc 513. A positioning column 514 is inserted into the positioning groove 512. The end of the rotating shaft one 511 away from the positioning column 514 is fixedly connected to the center of the side surface of the lower die 4. The end face of the positioning column 514 away from the rotating shaft one 511 is fixedly connected to the center of the side surface of the sealing disc 513. An air inlet pipe 515 and an air outlet pipe 516 that are communicated with the inside of the sealing cavity 518 are fixedly connected inside the left fixed seat 51. A one-way valve 517 is fixedly installed at the output end of the air outlet pipe 516.

[0038] In this implementation scheme, during the stamping process, the upper die 3 drives the driving column 57 and the positioning block 58 to move downward. The positioning block 58 pushes the convex block 56 to flip, keeping the sliding column 55 and the positioning column 514 stable. The positioning column 514 is firmly inserted into the positioning groove 512, ensuring that the lower die 4 does not rotate, providing a stable support basis for the stamping operation, effectively improving the stability of the stamping process, and further improving the forming accuracy of the stamped parts. Through structures such as the sealing cavity 518, the spring 59, the air inlet pipe 515, and the air outlet pipe 516, after the sealing disc 513 moves leftward to discharge the air in the sealing cavity 518, due to the small diameter of the air inlet pipe 515, the external air slowly enters, causing the sealing disc 513 to only slowly reset, preventing the sealing disc 513 from quickly resetting due to the elasticity of the spring 59, avoiding the positioning column 514 quickly inserting into the positioning groove 512 resulting in the inability of the rotating shaft one 511 to rotate, thereby protecting the servo motor 65, extending the service life of the equipment, and reducing the equipment maintenance cost.

[0039] Specifically, the flipping and vibrating assembly 6 includes a right fixed seat 61 fixedly connected inside the base 1. A second bearing 62 is fixedly installed inside the right fixed seat 61. The inner ring of the second bearing 62 is fixedly connected to a second rotating shaft 63. A toothed ring 64 is fixedly sleeved on the outer surface of the second rotating shaft 63. A servo motor 65 is fixedly installed inside the right fixed seat 61. One end of the second rotating shaft 63 away from the servo motor 65 is fixedly connected to the center of the side surface of the lower mold 4. The output end of the servo motor 65 is fixedly connected to the end surface of the second rotating shaft 63. A square groove 66 is formed outside the toothed ring 64 inside the right fixed seat 61. An abutting assembly 67 is installed on the inner wall of the square groove 66.

[0040] In this embodiment, after pressing is completed, when the servo motor 65 is started, it drives the second rotating shaft 63 to rotate, thereby driving the lower mold 4 to flip 180 degrees. At the same time, the toothed ring 64 and the abutting assembly 67 cooperate with each other. When the toothed ring 64 rotates, it acts on the abutting plate 673 in the abutting assembly 67, causing the abutting plate 673 to rotate and generate vibration. This combination of flipping and vibration can more efficiently demold the formed sheet metal part, avoiding damage to the surface of the sheet metal part by the traditional ejector pin demolding method and ensuring the production quality of the sheet metal part.

[0041] Specifically, the abutting assembly 67 includes a fixing plate 671 fixedly connected inside the square groove 66. Rotating grooves 672 are equidistantly formed on the surface of the fixing plate 671 close to the toothed ring 64. An abutting plate 673 is rotatably connected inside the rotating grooves 672. An upper elastic block 674 is fixedly connected to the top end inside the rotating grooves 672. A lower elastic block 675 is fixedly connected to the bottom end inside the rotating grooves 672. The base 1 is in an "n" shape.

[0042] In this embodiment, the abutting plate 673 in the abutting assembly 67 meshes with the surface of the toothed ring 64. When the toothed ring 64 rotates with the second rotating shaft 63, the abutting plate 673 rotates inside the rotating groove 672. The upper elastic block 674 and the lower elastic block 675 provide an elastic reset function, causing the abutting between the abutting plate 673 and the toothed ring 64 to generate a vibration effect, thereby assisting the lower mold 4 to achieve more efficient demolding during the flipping process and further improving the demolding quality.

[0043] Specifically, the surface of the positioning block 58 close to the convex block 56 is arc-shaped, and the surface of the convex block 56 close to the positioning block 58 is arc-shaped. A coil spring is installed at the connection between the convex block 56 and the sliding column 55. In the normal state, due to the elasticity of the coil spring, the convex block 56 rotates counterclockwise until the convex block 56 is parallel to the positioning post 514.

[0044] In the present embodiment, the arc-shaped surface design of the positioning block 58 and the protrusion 56 enables them to transmit force more smoothly when interacting with each other. Under normal circumstances, the protrusion 56 rotates counterclockwise under the action of the coil spring until it is parallel to the positioning column 514. During stamping, the positioning block 58 moves downward to push the protrusion 56 to rotate clockwise, ensuring that the positioning column 514 is stably inserted in the positioning groove 512. After the stamping is completed, the positioning block 58 moves upward and squeezes against the arc-shaped surface of the protrusion 56, so that the protrusion 56 drives the sealing disk 513 to move, so that the positioning column 514 is separated from the positioning groove 512, triggering the subsequent demolding action. The whole process is tightly connected and reliable.

[0045] Specifically, the touch switch 53 controls the servo motor 65 to open and close through the controller. When the touch switch 53 is started, the starter controls the servo motor 65 to rotate and drives the lower mold 4 to rotate 180 degrees.

[0046] In this embodiment, when the positioning column 514 is completely separated from the positioning groove 512 and the sliding column 55 abuts against the touch switch 53, the controller can accurately control the servo motor 65 to start, driving the lower mold 4 to flip 180 degrees, realizing an automated demolding process, and improving production efficiency and the accuracy of the production process.

[0047] Specifically, a limiting hole 551 is formed through the interior of the sliding column 55, and the sliding column 55 is slidably connected to the outer surface of the fixed rod 54 through the limiting hole 551. A sealing gasket 552 is fixedly connected to the interior of the left fixed seat 51, and the inner wall of the sealing gasket 552 is sealingly fitted to the outer surface of the sliding column 55. The sliding column 55 is sealed and slidably connected to the interior of the positioning column 514 through the sealing gasket 552, and the sliding column 55 is "L" shaped.

[0048] In this embodiment, the limiting hole 551 enables the sliding column 55 to slide stably on the fixed rod 54 to ensure the accuracy of its movement trajectory. The sealing gasket 552, on the one hand, seals and fits the outer surface of the sliding column 55 to prevent gas leakage. On the other hand, it enables the sliding column 55 to slide in a sealed manner within the positioning column 514 to ensure the sealing of the sealing cavity 518, thereby ensuring the normal operation of the positioning and starting assembly 5. The "L"-shaped design of the sliding column 55 is convenient for connection and cooperation with other components, such as the connecting protrusion 56 and the sealing disk 513, to achieve coordinated movement between the components.

[0049] Specifically, one end of the spring 59 abuts against the inner wall of the sealing chamber 518, and the other end of the spring 59 abuts against the surface of the sealing disk 513. Under normal conditions, the elasticity of the spring 59 causes the sealing disk 513 to slide toward the direction close to the rotating shaft 511.

[0050] In this embodiment, the elastic effect of the spring 59 causes the sealing disc 513 to slide towards the direction close to the first rotating shaft 511 under normal conditions, keeping the positioning column 514 inserted into the positioning groove 512, which guarantees the stability of the lower die 4 during stamping. At the same time, during the demolding process, in cooperation with structures such as the sealing cavity 518, the air inlet pipe 515, and the air outlet pipe 516, it prevents the rapid reset of the sealing disc 513 and protects the servo motor 65.

[0051] Specifically, the outside of the left fixing seat 51 is connected to the inside of the sealing cavity 518 through the air inlet pipe 515. The inside of the sealing cavity 518 is connected to the outside of the left fixing seat 51 through the air outlet pipe 516 and the one-way valve 517. The output end of the one-way valve 517 faces the outside of the left fixing seat 51. The diameter of the air outlet pipe 516 is much larger than that of the air inlet pipe 515. A sealing ring is fixedly installed on the outer surface of the sealing disc 513, and it is hermetically and slidably connected to the inside of the sealing cavity 518 through the sealing ring. Both the positioning groove 512 and the positioning column 514 are hexagonal.

[0052] In this embodiment, the air inlet pipe 515 and the air outlet pipe 516 cooperate with the one-way valve 517 to control the gas inlet and outlet in the sealing cavity 518. The diameter of the air outlet pipe 516 is much larger than that of the air inlet pipe 515, ensuring the slow reset of the sealing disc 513 and protecting the servo motor 65. The sealing ring on the outer surface of the sealing disc 513 ensures the sealing performance of the sealing cavity 518, making the gas control effect better. The positioning groove 512 and the positioning column 514 are hexagonal, which can better realize the positioning function, prevent the first rotating shaft 511 from rotating during stamping, and improve the stamping stability and accuracy.

[0053] Specifically, the surface of the abutting plate 673 close to the toothed ring 64 is arc-shaped, and the surface of the abutting plate 673 is meshed with the surface of the toothed ring 64. Both the upper elastic block 674 and the lower elastic block 675 are silicone plates, and the height of the upper elastic block 674 is greater than that of the lower elastic block 675.

[0054] In this embodiment, the arc-shaped surface design of the abutting plate 673 close to the toothed ring 64 makes it more tight and stable when meshing with the toothed ring 64, which is beneficial to generating a vibration effect. Both the upper elastic block 674 and the lower elastic block 675 are silicone plates and the height of the upper elastic block 674 is greater than that of the lower elastic block 675. When the abutting plate 673 rotates clockwise, that is, when the upper die 3 moves downward to stamp the object and the toothed ring 64 rotates, through the abutment with the abutting plate 673, the abutting plate 673 can have a larger rotation angle, and the reset effect received by the lower elastic block 675 is weakened, so the rotation effect is weakened, avoiding the drawback that the sheet metal part moves inside the lower die 4 and disengages from the inner cavity of the lower die 4 during the stamping process.

[0055] In summary, during use, place the sheet metal part on the lower die 4, drive the upper die 3 to slide downwards through the air cylinder, and stamp the sheet metal part into a specified shape by the coincidence of the upper die 3 and the lower die 4. During the downward movement of the upper die 3, the upper die 3 drives the driving column 57 to slide downwards, and the driving column 57 drives the positioning block 58 to slide downwards. When the positioning block 58 moves downwards, it will drive the convex block 56 to rotate clockwise. At this time, the sliding column 55 will not slide, so the positioning column 514 still stably plugs into the positioning groove 512. Therefore, the lower die 4 will not rotate during stamping, providing stable support for the lower die 4 and ensuring the stability of the stamping process;

[0056] After one stamping is completed, the upper die 3 will slide away from the base 1. The upper die 3 drives the positioning block 58 to slide upwards through the driving column 57. When the driving column 57 slides upwards, the positioning block 58 will slide upwards from the bottom of the convex block 56 and drive the convex block 56 to slide away from the positioning block 58 through the extrusion on the surface of the convex block 56. At the same time, the convex block 56 drives the sealing disc 513 to slide leftwards through the sliding column 55. The sealing disc 513 drives the positioning column 514 to slowly disengage from the inside of the positioning groove 512. When the sliding column 55 slides to a certain position, the positioning column 514 completely disengages from the inside of the positioning groove 512 until the surface of the sliding column 55 abuts against the surface of the touch switch 53, which can start the servo motor 65. The servo motor 65 drives the second rotating shaft 63 to rotate. At this time, the second rotating shaft 63 drives the lower die 4 to rotate counterclockwise by 180 degrees and then stops. When the second rotating shaft 63 rotates, through the abutment of the toothed ring 64 and the abutment plate 673, it will drive the abutment plate 673 to rotate upwards, and through the elasticity of the rotating groove 672, in cooperation with the engagement of the abutment plate 673 and the toothed ring 64, vibrate the second rotating shaft 63 and vibrate the lower die 4. Therefore, after the lower die 4 rotates and is combined with vibration, it can more efficiently demold the formed sheet metal part, and during the demolding process, it avoids the damage to the sheet metal part by the ejector rod during traditional demolding and also avoids the depression on the surface of the stamped sheet metal part caused by the external groove of the ejector rod, ensuring the production quality of the sheet metal part;

[0057] When the sliding column 55 drives the sealing disc 513 to slide leftwards, the air inside the sealing cavity 518 is discharged through the air outlet pipe 516 and the one-way valve 517. Even when the positioning block 58 does not contact the surface of the convex block 56, the external air can only slowly enter the sealing cavity 518 through the air inlet pipe 515. Therefore, the sealing disc 513 can only slowly reset, avoiding the trouble that due to the elasticity of the spring 59, the sealing disc 513 resets quickly, causing the positioning column 514 to quickly insert into the positioning groove 512, resulting in the inability of the first rotating shaft 511 to rotate and the lower die 4 to rotate, and damaging the servo motor 65.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
