Abstract
Description
Technical Field
[0001] This utility model relates to the field of production equipment technology, specifically to an automatic conveying device for a punch press. Background Technology
[0002] In modern industrial production, punch presses are an important processing equipment widely used in many fields such as automobile manufacturing, electronic equipment production, and hardware processing. They are used to stamp and form various raw materials such as sheet metal to manufacture parts of various shapes and specifications.
[0003] Traditional punch press conveyor systems primarily employ a continuous, linear layout. This involves a single belt conveyor feeding the product to the punch press, completing the stamping process, and then transferring the product via a subsequent, linearly connected conveyor belt. This conventional model can achieve economies of scale in large production sites with a single product type and high output. However, for many small manufacturing enterprises with limited space, this solution reveals significant drawbacks. Because a linear layout requires a large, continuous area, small factories cannot provide such a large production area for the punch press and conveyor equipment, severely hindering the realization of automated punch press conveying and capacity increases.
[0004] Furthermore, when faced with the production demands of products of different sizes and shapes, existing conveying equipment struggles to quickly adapt to changes in product specifications, frequently resulting in deviations in product positioning and conveying connections. Simultaneously, the coordination between existing conveying devices is insufficient. The transition from punching completion to subsequent conveying often suffers from problems such as uneven product pushing and product drops due to a lack of precise inter-equipment control. This not only reduces production continuity but can also damage products, increasing defect rates and production costs.
[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] A punch press, used for stamping products;
[0009] The first belt conveyor is connected to one side of the punch press and is used to transport the product to the punch press.
[0010] The second belt conveyor is connected to the other side of the punch press, and its setting direction is perpendicular to the setting direction of the first belt conveyor. It is used to receive the products processed by the punch press and to carry them out for subsequent transport.
[0011] A pushing mechanism is installed on the punch press and is aligned with the direction of the second belt conveyor. It is used to push the product after being punched by the punch press onto the second belt conveyor.

[0017] As a further embodiment of this utility model: the limiting and positioning mechanism includes a mounting bracket and a limiting component, the mounting bracket is gantry-shaped, and its bottom is connected to both sides of the second belt conveyor;
[0018] The limiting component is a set of symmetrically arranged limiting plates.

[0030] 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.
[0031] Please see Figure 1-3 In this embodiment of the present invention, an automatic conveying device for a punch press 1 includes:
[0032] Punch press 1: As the core processing equipment, it is used to stamp products. In the entire automatic conveying device, punch press 1 is located in the center. It receives the products to be processed from the first belt conveyor 2. After completing the stamping, it transfers the processed products to the subsequent conveying links.
[0033] First belt conveyor 2: docked on one side of punch press 1, its main function is to smoothly transport products to punch press 1. Through continuous and stable operation, it ensures that the products to be processed can accurately enter the processing station of punch press 1, and provides a stable material supply for the punching operation of punch press 1.
[0034] The second belt conveyor 3 is connected to the other side of the punch press 1 and is set perpendicular to the first belt conveyor 2. It is responsible for receiving the products processed by the punch press 1 and conveying them to the next stage. Its perpendicular setting to the first belt conveyor 2 effectively saves space and is especially suitable for small manufacturing enterprises with limited space. During the conveying process, the second belt conveyor 3 ensures that the products can be transferred smoothly and stably.
[0035] Pushing mechanism: Installed on the punch press 1 and corresponding to the direction of the second belt conveyor 3, this pushing mechanism is mainly used to push the product punched by the punch press 1 onto the second belt conveyor 3. Specifically, the pushing mechanism includes a cylinder 6 and a controller.
[0036] Cylinder 6: The piston rod of cylinder 6 is set towards the second belt conveyor 3. The product is pushed by the lateral extension and retraction of the piston rod. After the punch press 1 completes the punching, the piston rod of cylinder 6 extends and pushes the product from the punch press 1 station to the second belt conveyor 3.
[0037] Controller: Electrically connected to cylinder 6, it is used to precisely control the extension and retraction stroke and speed of the piston rod of cylinder 6, thereby adapting to the pushing needs of products of different sizes and weights. For example, for smaller and lighter products, the controller can be set to a smaller extension stroke and a lower speed to avoid excessive pushing force that could damage the product; for larger and heavier products, the extension stroke and speed are increased accordingly to ensure that the product can be smoothly pushed onto the second belt conveyor 3. In addition, the pushing mechanism is also equipped with a position sensor, which is located at the stamping station of punch press 1 and electrically connected to the controller controlling cylinder 6. It is used to detect the stamping completion signal. Once the punch press 1 is detected to have completed the stamping action, cylinder 6 is immediately triggered to push the product, ensuring precise coordination between the pushing action and the stamping action of punch press 1.
[0038] Guide plate 4: Connected between punch press 1 and second belt conveyor 3, it is used to carry the product pushed by the pushing mechanism and guide it to the second belt conveyor 3. The surface of guide plate 4 has a chute 7 formed along its length. Under the action of the pushing mechanism, the product is guided into the second belt conveyor 3 along the chute 7. The chute 7 can effectively prevent the product from deviating during the transfer process, ensuring that the product can fall accurately onto the second belt conveyor 3, and improving the accuracy and stability of the conveying.
[0039] Limiting and positioning mechanism 5: Installed on the second belt conveyor 3, used to limit the position of the product conveyed to the second belt conveyor 3, so that it is conveyed along the central direction of the second belt conveyor 3. The limiting and positioning mechanism 5 includes a mounting bracket 8 and a limiting component.
[0040] Mounting bracket 8: It is gantry-shaped, and its bottom is connected to both sides of the second belt conveyor 3, serving to support and fix the limiting components;
[0041] Limiting assembly: This consists of a set of symmetrically arranged limiting plates 9, which are arranged in a V-shape and have a first pair of interfaces 10 and a second pair of interfaces 11. The opening angle of the first pair of interfaces 10 is greater than that of the second pair of interfaces 11. The first pair of interfaces 10 faces the punch press 1. When the product is pushed from the punch press 1 onto the second belt conveyor 3, it first enters the first pair of interfaces 10. Guided by the V-shaped limiting plates 9, the product gradually moves towards the second pair of interfaces 11, ultimately achieving conveying along the central direction of the second belt conveyor 3. A track plate 12 with an internal guide rail is connected at the second pair of interfaces 11 to further ensure the product... The positioning accuracy during the conveying process is ensured. In addition, the limiting and positioning mechanism 5 is also equipped with a driving component 13, which is installed on the top of the mounting bracket 8. Its driving end passes through the mounting bracket 8 and connects to the top of the track plate 12. It is used to adjust the height of the track plate 12 and the limiting component relative to the second belt conveyor 3. By adjusting the height, it can adapt to the conveying requirements of products with different thicknesses and ensure the limiting and positioning effect. It is understood that the driving component 13 can also be detachably connected to the track plate 12 and the limiting component. When there is a need to change the conveying of products of different sizes, the track plate 12 and the limiting component can also be replaced to adapt to products of different sizes.
[0042] In practical applications, the pushing mechanism may be limited by the positioning table or positioning groove of the product corresponding to the lower die of the punch press 1, and cannot directly act on the product on the stamping station through the piston rod of the cylinder 6. In this regard, a conventional method can be adopted - installing an ejector device. Multiple ejector pins are set at the bottom of the positioning table or positioning groove of the lower die of the punch press 1. The product is placed in a position corresponding to the ejector pin. After the stamping is completed, the ejector pin is driven by another driving component such as the cylinder 6 to lift the ejector pin to a certain height, so that the product is removed from the positioning table or positioning groove. At this time, the cylinder 6 pushes the product to push it out smoothly. The cylinder 6 can be installed on the inner side of the punch press 1 and pushes the product by contacting it through a simple straight push rod.
[0043] In summary, the layout of the second belt conveyor 3 perpendicular to the first belt conveyor 2, combined with the push mechanism, greatly saves space, making it particularly suitable for small manufacturing enterprises with limited space. It helps to achieve efficient operation of the punch press 1 in a small space. The guide plate 4 and the limit positioning mechanism 5 ensure the accurate position of the product during the conveying process, effectively solving the problem of insufficient coordination between equipment in traditional solutions, improving production continuity, and reducing product damage rate and production costs.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
