Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and more specifically, to an automatic step-by-step blanking mechanism. Background Technology

[0002] Corrugated aluminum sheets are indeed a very effective and widely used heat dissipation method. Essentially, they are made by pressing a flat aluminum sheet into a corrugated shape, increasing the actual surface area several times over for the same projected area. Furthermore, aluminum is one of the most thermally conductive metals on Earth, with a thermal conductivity of approximately 200-240 W / (m·K). This means that heat can be conducted very quickly from the high-temperature point within the aluminum sheet to the entire surface.

[0003] However, during the production of aluminum corrugated sheets, due to the required dimensions, there are certain requirements for the number of corrugations in each setting. Furthermore, blank spaces need to be left at the beginning and end of the aluminum corrugated sheets to facilitate their installation. However, traditional production equipment continuously stamps the aluminum sheets, and the blank spaces can only be left manually. However, it is difficult to accurately control the length of the blank spaces that are manually pulled, which makes equipment operation difficult. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic step-skipping blanking mechanism, which can realize automatic step-skipping blanking, save manual assistance in the production of aluminum corrugated sheets, realize automated production and improve production efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic step-by-step blanking mechanism, including a bottom mold, a support platform that slides vertically on the bottom mold, a support slider that slides laterally on the bottom mold, and a driving mechanism for driving the support slider to move. The support platform and the support slider are provided with interlocking teeth that can mesh with each other. The driving mechanism pushes laterally along the inclined direction of the interlocking teeth to cause the support platform to slide vertically and rise and fall. The rising and falling of the support platform is used to switch between pressing and blanking on the surface.

[0006] Preferably, the driving mechanism includes a gear shaft that rotates on the bottom mold and a notch provided on the gear shaft, and the gear shaft is driven to rotate by an external force; When the support slider falls into the notch, the meshing teeth of the support platform and the support slider engage, and the support platform descends; When the support slider comes into contact with the gear shaft, the meshing teeth of the support platform and the support slider separate, and the support platform rises.

[0007] Preferably, the bottom mold is provided with an anti-reverse rotation mechanism to prevent the gear shaft from rotating in the opposite direction.

[0008] Preferably, the anti-reverse mechanism includes helical teeth surrounding the gear shaft, the helical teeth being evenly distributed along the axial direction of the gear shaft, and the bottom mold being provided with an anti-reverse component that pushes against the helical teeth; when the gear shaft rotates in the opposite direction to the direction of external force driving, the anti-reverse component can engage with the helical teeth.

[0009] Preferably, the anti-reverse component includes a top block disposed on the bottom mold, one end of the top block being hinged to the bottom mold, and the other end of the top block abutting against the elastic component.

[0010] Preferably, the elastic component includes a push rod that slides on the bottom mold and a spring connected to the push rod, wherein the spring force pushes the push rod.

[0011] In summary, the beneficial effects of this utility model are as follows: a support platform is set in the bottom mold, and the support platform is moved vertically by the drive mechanism along the inclined direction of the meshing teeth to make it slide and rise. By raising and lowering the support platform, the bottom mold can switch between pressing and blanking during stamping, thereby realizing automatic skipping blanking, saving manual assistance for the production of aluminum corrugated plates, realizing automated production, and improving production efficiency.

[0014] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0016] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] An automatic step-by-step blanking mechanism, see Figure 1 and Figure 2 It includes a bottom mold 1, a support platform 2 that slides vertically on the bottom mold 1, a support slider 3 that slides laterally on the bottom mold 1, and a drive mechanism 4 that drives the support slider 3 to move. There are interlocking teeth 31 between the support platform 2 and the support slider 3. The drive mechanism 4 pushes laterally along the inclined direction of the interlocking teeth 31 to make the support platform 2 slide vertically and rise and fall. The rising and falling of the support platform 2 is used to switch between pressing and leaving blank on the surface.

[0019] In this embodiment, a support platform 2 is set in the bottom mold 1. The drive mechanism 4 is used to push the support platform 2 horizontally along the inclined direction of the meshing teeth 31 to make the support platform 2 slide vertically and rise and fall. By raising and lowering the support platform 2, the bottom mold 1 can switch between pressing and blanking during stamping, thereby realizing automatic skipping blanking, saving manual assistance for the production of aluminum corrugated plates, realizing automated production, and improving production efficiency.

[0020] Specifically, the drive mechanism 4 includes a gear shaft 41 that rotates on the bottom mold 1 and a notch 42 provided on the gear shaft 41, and the gear shaft 41 is driven to rotate by an external force; When the support slider 3 falls into the notch 42, the meshing teeth 31 of the support platform 2 and the support slider 3 mesh, and the support platform 2 descends; When the support slider 3 comes into contact with the gear shaft 41, the meshing teeth 31 of the support platform 2 and the support slider 3 separate, and the support platform 2 rises.

[0021] The support platform 2 is in a high position, and the external force drives the gear shaft 41 to rotate.

[0022] When the notch 42 on the gear shaft 41 rotates to below the support slider 3, the support slider 3 loses its support and falls into the notch 42 under the action of gravity or other structures.

[0023] As the slider falls, the special meshing teeth 31 on the support platform 2 and the support slider 3 mesh with each other.

[0024] As gear shaft 41 continues to rotate, the drive teeth on it push the already lowered support slider 3 to move laterally. Since the meshing teeth 31 are inclined, the lateral movement of the slider forces the support platform 2 to slide downward, thus switching to the "blank" state.

[0025] In addition, the mechanism includes an anti-reverse mechanism 5, which acts like a ratchet and only allows the gear shaft 41 to rotate in one direction, preventing it from rotating in the opposite direction and causing the mechanism to malfunction, thus ensuring the reliability of the operation.

[0026] The anti-reverse mechanism 5 includes helical teeth 51 surrounding the gear shaft 41. The helical teeth 51 are evenly distributed along the axial direction of the gear shaft 41. The bottom mold 1 is provided with an anti-reverse component that pushes against the helical teeth 51. When the gear shaft 41 rotates in the opposite direction to the direction of external force driving, the anti-reverse component can engage with the helical teeth 51.

[0027] The anti-reverse component includes a top block 52 disposed on the bottom mold 1. One end of the top block 52 is hinged to the bottom mold 1, and the other end of the top block 52 abuts against the elastic component. The elastic component pushes the top block 52 in real time, and when the gear shaft 41 rotates, the elastic component can simultaneously retract the top block 52 to avoid interfering with the rotation of the gear shaft 41.

[0028] The elastic component includes a push rod 53 that slides on the bottom mold 1 and a spring 54 connected to the push rod 53, and the spring force of the spring 54 pushes the push rod 53.

[0029] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
