Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically an automatic stamping and blanking device for stamping metal sheets. Background Technology

[0002] In the field of metal processing, semi-finished raw materials are usually stamped into specific shapes on steel plates using a stamping process. In traditional production, stamped workpieces are usually removed in two ways: one is by manual removal, and the other is by automatic ejection using additional driving devices (such as robotic arms, ejection mechanisms, etc.).

[0003] However, all of the above methods have obvious drawbacks. Manual part handling is not only labor-intensive and inefficient, but also requires operators to be in close contact with the stamping equipment, posing a high safety hazard and easily leading to workplace accidents. While using automated drive devices can reduce manual intervention, it requires additional power mechanisms, transmission components, and control systems, resulting in increased equipment complexity and significantly higher manufacturing costs.

[0004] Therefore, how to design a technical solution that is simple in structure, low in cost, and can safely and efficiently remove stamped workpieces has become an urgent problem to be solved in this field. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses an automatic stamping and unloading device for stamped metal sheets.

[0006] This utility model provides an automatic stamping and unloading device for stamped metal sheets, including a stamping machine, a lifting stamping plate and a fixed bearing plate located directly below the stamping plate on the frame of the stamping machine, and also includes an unloading plate;

[0007] The feeding plate is movably connected to the frame via a connecting rod assembly;

[0008] The stamping plate is equipped with an adsorption component for adsorbing or releasing the stamped sheet material;

[0009] When the stamping plate moves down to stamp, the blanking plate moves away from the outside of the frame;

[0010] As the stamping plate moves upward, the adsorption component moves the stamped sheet upward, and the unloading plate approaches the frame to directly below the stamping plate.

[0011] Furthermore, a suction cup is also installed on the stamping plate; the suction cup is positioned such that when the stamping plate comes into contact with the metal plate, the suction cup adsorbs the metal plate.

[0012] Furthermore, the suction chamber at the lower end of the suction cup is connected to an air pump via a pipe.

[0013] Furthermore, the linkage assembly is a scissor type, and it is connected to the frame in two places: one is hinged to the lifting seat that fixes the stamping plate, and the other is hinged to the support that fixes the pressure plate.

[0014] Furthermore, the linkage assembly includes a first linkage and a second linkage; one end of the first linkage is hinged to the lifting seat; one end of the second linkage is hinged to the support; the center positions of the first linkage and the second linkage are hinged through a first hinge shaft; the unloading plate is fixedly connected to the first hinge shaft.

[0015] Furthermore, the linkage assembly also includes a third link and a fourth link; one end of the third link is hinged to the other end of the first link, and one end of the fourth link is hinged to the other end of the second link; the other end of the third link and the other end of the fourth link are hinged through a second hinge shaft; the blanking plate is sleeved on the first hinge shaft and the second hinge shaft.

[0016] Furthermore, the linkage assembly also includes a movable rod; the end of the movable rod away from the frame is hinged to the second hinge shaft; a groove extending in the length direction is provided at the middle position of the movable rod; the first hinge shaft is engaged in the groove; the end of the feed plate near the frame is fixedly connected to the end of the movable rod near the frame.

[0017] Furthermore, the feed plate is arranged at an angle, with its high end located near the frame.

[0018] The beneficial effects of this utility model are:

[0019] 1. No additional drive motor, pneumatic components or complex control system are required. The material plate is moved by the lifting motion of the press itself, which effectively reduces equipment cost and maintenance difficulty.

[0020] 2. The blanking plate automatically receives and removes the workpiece as the stamping plate moves upward, eliminating the need for manual removal throughout the process. This avoids the safety risks of operators coming into contact with the stamping area and significantly improves production efficiency, making it suitable for continuous batch production.

[0021] 3. The mechanical linkage of the linkage assembly ensures that the blanking plate and the stamping plate move synchronously, the blanking position is accurate, and it can stably process stamping parts of different sizes; at the same time, the overall structure is compact and easy to integrate into existing stamping equipment, making it convenient for modification.

[0022] 4. The material feeding is driven by the stamping press itself, requiring no additional energy consumption. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] like Figure 1-5 As shown, this utility model discloses an automatic stamping and unloading device for stamped metal sheets, including a stamping machine. A liftable stamping plate 2 and a fixed bearing plate 3 are arranged on the same side of the machine frame 1. The stamping plate 2 is mounted on the lower end of a lifting seat 6 driven by a hydraulic cylinder, and the bearing plate 3 is mounted on the upper end of a fixed support 7. A groove of a preset shape is formed at the upper end of the bearing plate 3, and a protrusion forming a block that conforms to the groove is provided at the lower end of the stamping plate 2. When a steel sheet is placed on the upper end of the bearing plate 3 and the stamping plate 2 presses down, the forming block engages with the groove, and the sheet material of the preset shape is stamped and formed.

[0032] This embodiment also includes a blanking plate 4 for transferring the stamped sheet metal, allowing it to detach from the stamping machine. The blanking plate 4 is movably connected to the frame 1 via a scissor-type linkage assembly. The linkage assembly includes a first link 8, a second link 9, a third link 11, a fourth link 12, and a moving rod 14. One end of the first link 8 is hinged to the lifting seat 6; one end of the second link 9 is hinged to the support 7; the center positions of the first link 8 and the second link 9 are hinged via a first hinge shaft 10. One end of the third link 11 is hinged to the other end of the first link 8, and one end of the fourth link 12 is hinged to the other end of the second link 9; the other ends of the third link 11 and the fourth link 12 are hinged via a second hinge shaft 13. The end of the moving rod 14 away from the frame 1 is hinged to the second hinge shaft 13; a slide groove 15 extending in the length direction is provided at the middle position of the moving rod 14; the first hinge shaft 10 is engaged in the slide groove 15; the end of the feeding plate 4 near the frame 1 is fixedly connected to the end of the moving rod 14 near the frame 1.

[0033] With this configuration, when the stamping plate 2 moves down to stamp, the blanking plate 4 moves away from the outside of the frame 1; when the stamping plate 2 moves up, the blanking plate 4 moves towards the frame 1 and moves to a position directly below the stamping plate 2.

[0034] An adsorption component 5 is also installed at the center of the stamping plate 2 to adsorb or release the stamped sheet. When the stamping plate 2 is pressed down, the adsorption component 5 adsorbs the sheet; after stamping is completed, the stamped sheet moves upward with the stamping plate 2; when the cutting plate 4 moves directly below the stamping plate 2, the adsorption component 5 loses its adsorption capacity and releases the sheet, causing it to fall onto the cutting plate 4, thus facilitating the transfer of the stamped sheet by the cutting plate 4.

[0035] In this embodiment, the feeding plate 4 is arranged at an angle, with its upper end close to the frame 1. With this arrangement, the material can slide on the feeding plate 4 and be automatically collected.

[0036] In this embodiment, the adsorption component 5 is a suction cup, and its lower adsorption chamber is connected to an air pump via an air pipe. The air pump draws in and inflates the material to complete the adsorption or release of the sheet. In other embodiments, if the sheet can be attracted by a magnet, the adsorption component 5 can also be an electromagnet, which performs the adsorption or release of the sheet by switching the power on and off.

[0037] Compared to existing technologies, the advantages of this embodiment are: 1. No additional drive motor, pneumatic components, or complex control systems are required. The movement of the blanking plate 4 is driven solely by the lifting motion of the stamping press itself, effectively reducing equipment costs and maintenance difficulty. 2. The blanking plate 4 automatically receives and removes the workpiece as the stamping plate 2 moves upward, eliminating the need for manual removal throughout the process. This avoids the safety risks of operators coming into contact with the stamping area and significantly improves production efficiency, making it suitable for continuous batch production. 3. The mechanical linkage of the linkage assembly ensures that the blanking plate 4 and the stamping plate 2 move synchronously, resulting in precise blanking positions and stable processing of stamped parts of different sizes. Furthermore, the overall structure is compact, making it easy to integrate into existing stamping equipment and facilitating retrofitting. 4. The blanking is driven by the stamping press's own power, requiring no additional energy consumption.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
