Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly to a stamping mold with an automatic part-taking structure. Background Art

[0002] As the core process equipment for stamping, a stamping mold can separate or form metal or non-metal materials under the power of a press (punch press) through the cooperation of the upper and lower molds. Its working process is as follows: after the punch descends to complete blanking or forming, the material adheres to the upper mold due to the vacuum adsorption effect of the punch or the viscosity of the lubricating oil. The material needs to be ejected through the ejection structure in the upper mold cavity. However, the ejected material is easily retained between the upper and lower molds, hindering the closing of the mold, resulting in the need to manually stop the machine to take out the formed material after each stamping. This problem is particularly prominent in high-speed stamping scenarios. Frequent stopping will significantly reduce production efficiency. If a manipulator is used to take parts, although it can reduce manual intervention, it will increase the equipment investment cost and has poor applicability. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the prior art, the present invention provides a stamping mold with an automatic part-taking structure, which solves the problems that the material is easily retained between the upper and lower molds after being ejected by the traditional stamping mold, resulting in the need for manual shutdown to take parts, frequent shutdowns in high-speed stamping scenarios, low production efficiency, and high cost and poor applicability of using a manipulator to take parts.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A stamping mold with an automatic part-taking structure includes a stamping mold main body, a lower mold and an upper mold installed on the stamping mold main body. A fixed seat is fixedly connected to the side of the stamping mold main body. A support seat is fixedly connected to the surface of the fixed seat away from the stamping mold main body. A swing assembly is installed between the upper mold and the support seat. The output end of the swing assembly is located between the lower mold and the upper mold. A belt conveyor is fixedly installed inside the fixed seat. The swing assembly is located directly above the belt conveyor.

[0007] Further, the swing assembly includes a fixed block fixedly connected to the surface of the upper mold. A rotating plate is rotatably connected to the surface of the fixed block. An end face of the rotating plate away from the fixed block is rotatably connected to a fixed plate. A fixed platform is fixedly connected to the surface of the support seat close to the upper mold. A chute is opened inside the fixed platform. A fixed rod is fixedly connected to the inner wall of the chute. The fixed plate is slidably connected to the outer surface of the fixed rod. A flipping assembly is installed inside the fixed platform.

[0008] Further, the flipping assembly includes a sliding plate slidably connected inside the chute. A rotating shaft is rotatably connected inside the sliding plate through a bearing. A threaded rod is fixedly connected to the end face of the rotating shaft away from the stamping die body. A sleeve is sleeved on the outer surface of the threaded rod. A square box is fixedly connected to the end face of the rotating shaft away from the threaded rod. A rotating plate is rotatably connected to the surface of the square box. A blanking assembly is installed at the connection between the rotating plate and the sliding plate.

[0009] Further, the blanking assembly includes an annular groove opened on the side surface of the sliding plate. An external gear ring is fixedly connected inside the annular groove. A first gear is meshed with the surface of the external gear ring. A first rotating rod is fixedly connected to the center of the surface of the first gear. A second gear is fixedly connected to the end face of the first rotating rod away from the first gear. A second rotating rod is fixedly connected to the side surface of the rotating plate.

[0010] Further, a positioning rod is fixedly connected to the inner wall of the sleeve. The end face of the positioning rod is arc-shaped. The end face of the positioning rod is inserted into the thread groove on the surface of the threaded rod. The outer surface of the sleeve is fixedly connected inside the fixed table.

[0011] Further, a limiting groove is penetrated and opened on the surface of the flipping assembly. The fixed rod is inserted into the limiting groove.

[0012] Further, the chute is "T"-shaped. The outer surface of the sliding plate is slidably connected inside the chute.

[0013] Further, the square box is rotatably connected to the side surface of the sliding plate through a rotating shaft.

[0014] Further, the first rotating rod is rotatably connected inside the square box through a bearing. The second rotating rod is rotatably connected inside the square box through a bearing. Both the second gear and the second rotating rod are rotatably connected inside the square box.

[0015] Further, the output end of the belt conveyor extends to the outside of the support seat. A rubber plate is fixedly connected inside the square box.

[0016] (III) Beneficial Effects

[0017] The present invention has the following beneficial effects:

[0018] (1) The stamping die with automatic pick-up structure is designed with a linkage between a swing component and a flip component. When the upper die completes stamping and moves upward, the swing component drives the square box to move to the bottom of the lower die to receive the material ejected by the upper die. When the upper die moves downward again to stamp, the square box flips and pours the material into the belt conveyor, thus realizing an automatic cycle of "pick-up - transfer - unloading". This process does not require manual intervention, significantly reduces the shutdown frequency in high-speed stamping scenarios, avoids the obstruction of die closing caused by material retention, and greatly improves production efficiency.

[0019] (2) The stamping die with automatic pick-up structure has a swinging assembly that uses a hinged structure of a fixed block, a rotating plate and a fixed plate to drive the mechanical arm to pick up the parts by the up and down movement of the upper die. No additional power source is required. The threaded rod and the positioning rod in the flipping assembly cooperate to achieve a 90° flip of the square box through mechanical transmission, replacing the complex electronic control system of the traditional manipulator. The overall structure is integrated on the side of the mold body, occupying a small space, and the equipment cost is lower than that of the traditional manipulator picking solution, and the maintenance difficulty is lower.

[0020] (3) The stamping die with automatic picking structure has a material removal component that is driven by the meshing of the external gear ring, gear and toothed belt, so that when the square box is flipped, the turntable rotates synchronously and forms a barrier to prevent the material from falling during the transfer process. The rubber plate inside the square box increases the friction to prevent the material from sliding and deflecting. At the same time, the limit design of the "T"-shaped slide groove and the fixed rod ensures the accuracy of the sliding plate's moving path, and cooperates with the insertion of the limit groove and the fixed rod to avoid component shaking, thereby ensuring the reliability of the picking and unloading actions and increasing the success rate of material transfer.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0035] Please refer to Figure 1-10The embodiment of the present invention provides a technical solution: a stamping die with an automatic part picking structure, comprising a stamping die main body 1 and a lower die 2 and an upper die 3 installed on the stamping die main body 1, a fixed seat 4 is fixedly connected to the side of the stamping die main body 1, a surface of the fixed seat 4 away from the stamping die main body 1 is fixedly connected to a support seat 5, a swing assembly 6 is installed between the upper die 3 and the support seat 5, an output end of the swing assembly 6 is located between the lower die 2 and the upper die 3, a belt conveyor 7 is fixedly installed inside the fixed seat 4, and the swing assembly 6 is located directly above the belt conveyor 7.

[0036] Specifically, the swing assembly 6 includes a fixed block 61 fixedly connected to the surface of the upper mold 3, the surface of the fixed block 61 is rotatably connected to a rotating plate 62, the end surface of the rotating plate 62 away from the fixed block 61 is rotatably connected to a fixed plate 63, the surface of the support seat 5 close to the upper mold 3 is fixedly connected to a fixed platform 64, a slide groove 65 is opened inside the fixed platform 64, the inner wall of the slide groove 65 is fixedly connected to a fixed rod 66, the fixed plate 63 is slidably connected to the outer surface of the fixed rod 66, and a flip assembly 67 is installed inside the fixed platform 64.

[0037] In this embodiment, through the hinged structure of the fixed block 61, the rotating plate 62 and the fixed plate 63, the up and down movement of the upper mold 3 is used to drive the robotic arm type picking action. When the upper mold 3 moves upward, the rotating plate 62 drives the fixed plate 63 to slide along the fixed rod 66, so that the flipping assembly 67 such as the square box 675 moves to the bottom of the lower mold 2 to receive the material. When the upper mold 3 moves downward, it drives the flipping assembly 67 to reset and flip the material. No additional power source is required, and the automatic drive of the picking action is realized.

[0038] Specifically, the flipping assembly 67 includes a sliding plate 671 slidably connected to the inside of the slide groove 65, the interior of the sliding plate 671 is rotatably connected to a rotating shaft 672 through a bearing, the end face of the rotating shaft 672 away from the stamping die body 1 is fixedly connected to a threaded rod 673, the outer surface of the threaded rod 673 is sleeved with a sleeve 674, the end face of the rotating shaft 672 away from the threaded rod 673 is fixedly connected to a square box 675, the surface of the square box 675 is rotatably connected to a rotating plate 676, and a blanking assembly 8 is installed at the connection between the rotating plate 676 and the sliding plate 671.

[0039] In this embodiment, the threaded rod 673 cooperates with the positioning rod 6741 of the sleeve 674. When the sliding plate 671 slides along the slide groove 65, the threaded rod 673 automatically rotates under the action of the positioning rod 6741 in the sleeve 674, and the 90° flipping of the square box 675 is achieved through mechanical transmission, replacing the complex electrical control system of the traditional manipulator, with a compact structure and low cost.

[0040] Specifically, the unloading component 8 includes an annular groove 81 opened on the side of the sliding plate 671, the inside of the annular groove 81 is fixedly connected to an outer toothed ring 82, the surface of the outer toothed ring 82 is meshingly connected to a gear 1 83, a rotating rod 1 84 is fixedly connected at the center of the surface of the gear 1 83, the end face of the rotating rod 1 84 away from the gear 1 83 is fixedly connected to a gear 2 85, the side of the rotating plate 676 is fixedly connected to a rotating rod 2 86, the end face of the rotating rod 2 86 is fixedly connected to a gear 3 87, and the outer surfaces of the gear 3 87 and the gear 2 85 are meshingly installed with a toothed belt 88.

[0041] In this embodiment, when the square box 675 is flipped, gear one 83 rotates along the outer gear ring 82, and drives gear three 87 to rotate synchronously through gear two 85 and toothed belt 88, so that the rotating plate 676 forms an enclosure or opens. When the square box 675 is flipped 90° clockwise, the rotating plate 676 rotates 90° clockwise synchronously to enclose the side of the square box 675 to prevent materials from falling. When the square box 675 is flipped counterclockwise to unload materials, the rotating plate 676 opens to ensure that the materials can be poured out smoothly.

[0042] Specifically, the inner wall of the sleeve 674 is fixedly connected with a positioning rod 6741 , the end face of the positioning rod 6741 is arc-shaped, the end face of the positioning rod 6741 is inserted into the thread groove on the surface of the threaded rod 673 , and the outer surface of the sleeve 674 is fixedly connected to the inside of the fixed platform 64 .

[0043] In this embodiment, the arc-shaped end surface thereof engages with the thread groove of the threaded rod 673 , ensuring that the threaded rod 673 rotates passively only when sliding, avoiding idling, and accurately controlling the flipping angle of the square box 675 .

[0044] Specifically, a limiting groove 631 is formed through the surface of the flip assembly 67 , and the fixing rod 66 is inserted into the limiting groove 631 .

[0045] In this embodiment, the limiting groove 631 is plugged into the fixing rod 66 to limit the moving direction of the flip assembly 67 to avoid shaking, ensure that the sliding plate 671 moves linearly along the fixing rod 66, and improve the stability of the mechanism.

[0046] Specifically, the slide groove 65 is “T”-shaped, and the outer surface of the sliding plate 671 is slidably connected to the inside of the slide groove 65 .

[0047] In this embodiment, the “T”-shaped slide groove 65 cooperates with the sliding plate 671 to prevent the sliding plate 671 from being separated from the fixed platform 64, thereby ensuring the accuracy and reliability of the movement of the component.

[0048] Specifically, the square box 675 is rotatably connected to the side of the sliding plate 671 via the rotating shaft 672 .

[0049] In this implementation, the square box 675 is connected to the sliding plate 671 through the rotating shaft 672 to ensure the stability of the flipping action. In cooperation with the movement path of the swinging assembly 6, the "pick-up - transfer - blanking" cycle is accurately completed.

[0050] Specifically, the first rotating rod 84 is rotatably connected inside the square box 675 through a bearing, the second rotating rod 86 is rotatably connected inside the square box 675 through a bearing, and both the second gear 85 and the second rotating rod 86 are rotatably connected inside the square box 675.

[0051] In this implementation, by setting bearings, the stability of the rotation of the first rotating rod 84 and the second rotating rod 86 is ensured, and the accuracy of the rotation angle of the square box 675 is guaranteed.

[0052] Specifically, the output end of the belt conveyor 7 extends to the outside of the support seat 5, and a rubber plate is fixedly connected inside the square box 675.

[0053] In this implementation, the output end of the belt conveyor 7 extends to the outside of the support seat 5, which is convenient for the rapid export of materials and docking with the subsequent production line, improving the automation efficiency. The rubber plate fixedly connected inside the square box 675 can prevent damage caused by impact when the materials fall.

[0054] During operation, the upper die 3 slides downward to stamp the sheet metal, and then the upper die 3 slides upward. The upper die 3 drives the fixed plate 63 to slide leftward through the rotating plate 62, and the fixed plate 63 drives the sliding plate 671 to slide leftward, and the square box 675 slides downward to directly below the lower die 2. When the sliding plate 671 slides leftward, the threaded rod 673 is driven to slide leftward through the rotating shaft 672. Through the engagement of the threaded rod 673 with the positioning rod 6741, the threaded rod 673 is driven to rotate clockwise. The threaded rod 673 drives the square box 675 to rotate clockwise through the rotating shaft 672. When the sliding plate 671 cannot slide anymore, the square box 675 just flips 90 degrees. At the same time, the square box 675 is directly below the upper die 3. The ejecting structure inside the upper die 3 ejects the material and directly drops it into the square box 675. When the upper die 3 stamps again, the upper die 3 slides downward and drives the fixed plate 63 to slide rightward through the fixing block 61 and the rotating plate 62. The fixed plate 63 drives the sliding plate 671 to slide rightward, and the sliding plate 671 drives the rotating shaft 672 and the threaded rod 673 to slide rightward. Through the engagement of the threaded rod 673 with the positioning rod 6741, the threaded rod 673 and the rotating shaft 672 are driven to rotate in the reverse direction. When the sliding plate 671 cannot slide rightward anymore, the square box 675 flips 90 degrees, and the materials collected inside the square box 675 can be poured onto the belt conveyor 7 and conveyed to the specified position through the belt conveyor 7;

[0055] When the square box 675 rotates clockwise, through the meshing of the first gear 83 and the external tooth ring 82, the first gear 83 can rotate clockwise on the surface of the external tooth ring 82. The first gear 83 drives the second gear 85 to rotate clockwise through the first rotating rod 84. The second gear 85 drives the third gear 87 to rotate clockwise through the toothed belt 88. The third gear 87 drives the rotating plate 676 to rotate clockwise through the second rotating rod 86. When the square box 675 rotates 90 degrees, the rotating plate 676 also just rotates 90 degrees, ensuring that when the rotating plate 676 rotates 90 degrees clockwise, the rotating plate 676 can block the side of the square box 675, avoiding the object from falling outside the square box 675 when it falls on the square box 675. When the square box 675 rotates counterclockwise, the rotating plate 676 will also rotate counterclockwise, and the side of the square box 675 can be opened to facilitate the pouring of the materials inside the square box 675.
