Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and in particular to an anti-gravity tilting mechanism and a stamping die. Background Technology

[0002] With the development of the times, all industries are transforming towards automation and intelligence, and automobile production and stamping parts production are no exception. In automated parts production, parts need to maintain stability in each process. In particular, some stamping parts with special shapes use special mold structures to solve the stability of automated production and improve production efficiency in order to ensure the forming quality of the stamping parts. However, in the current stamping process, when the robotic arm picks up and places the parts, multiple floating blocks are set on the mold to support the material sheet during the stamping process. However, the current floating blocks are fixed and only have a positioning function. Due to the unstable center of gravity of the parts, the upper and lower molds are prone to mis-pressing the parts during the stamping process, which may cause the mold to be scrapped. After the stamping is completed, the stamped parts still need to be manually removed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an anti-gravity tilting mechanism to solve the technical problems in the prior art where the floating material block is fixed and only has a positioning function, and the parts are unstable due to the center of gravity, requiring manual removal of the stamped parts.

[0004] To achieve the above and other related objectives, this utility model provides an anti-tilting mechanism, comprising:

[0005] A base, on which a sliding groove is provided, and a driving block is slidably disposed within the sliding groove;

[0006] A telescopic device is provided on the base and is used to drive the drive block to slide within the sliding groove.

[0007] A floating block is located directly above the sliding groove. The lower end face of the floating block is an inclined surface, and the upper end face of the driving block is an inclined surface that matches the lower end face of the floating block. When the telescopic device is used to drive the driving block to insert below the floating block, the floating block rises. When the telescopic device is used to drive the driving block away from below the floating block, the floating block descends.

[0008] The advantage of adopting the above technical solution is that the floating block in this application can rise and fall with the extension and retraction of the telescopic device, allowing it to be adaptively adjusted according to the shape and center of gravity of the part. This effectively solves the problem of misalignment caused by the unstable center of gravity of the part during the stamping process. This improvement not only enhances the stability of the part and production efficiency, but also strengthens the protection of the mold and the stamping accuracy.

[0009] Optionally, the drive block may also have a buffer layer on its end face facing the telescopic device.

[0010] Optionally, a first guide plate is provided on the lower end inclined surface of the floating block, and a second guide plate is provided on the upper end inclined surface of the driving block.

[0011] Optionally, a plurality of third guide slides are provided on the side wall of the float block, and the third guide slides are arranged around the float block.

[0012] Optionally, the telescopic device is a cylinder, and the piston rod end of the telescopic device is connected to the drive block.

[0013] Optionally, a fourth guide plate is provided on the side of the drive block that contacts the sliding groove.

[0014] Optionally, the buffer layer is polyurethane.

[0015] Optionally, the first guide plate, the second guide plate, the third guide plate, and the fourth guide plate are all made of plastic.

[0016] Optionally, the outer surfaces of the first guide plate, the second guide plate, the third guide plate, and the fourth guide plate are all provided with a lubricating coating.

[0017] Optionally, a stamping die includes a lower die, the upper surface of which is provided with a plurality of positioning areas, and a plurality of the aforementioned anti-gravity tilting mechanisms are also provided inside the lower die, each of the anti-gravity tilting mechanisms corresponding to one of the positioning areas, and each of the floating blocks being located within the corresponding positioning area.

[0018] As described above, the anti-gravity tilting mechanism of this utility model has the following beneficial effects: Using the anti-gravity tilting mechanism of this application, the floating block can rise and fall with the extension and retraction of the telescopic device, allowing it to be adaptively adjusted according to the shape and center of gravity of the part. This effectively solves the problem of misalignment caused by an unstable center of gravity during the stamping process. This improvement not only enhances the stability of the part and production efficiency but also strengthens the protection of the mold and the stamping accuracy. Attached Figure Description

[0034] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0035] Please see Figures 1 to 5It should be noted that the illustrations provided in this embodiment are merely schematic representations of the basic concept of this utility model. The illustrations only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components in implementation.

The structures, proportions, sizes, etc., shown in the accompanying drawings are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0036] Please see Figures 1 to 5 As shown, this utility model provides an anti-tilting mechanism, comprising:

[0037] A base 1 is provided with a sliding groove, and a driving block 101 is slidably disposed in the sliding groove;

[0038] Telescopic device 2 is disposed on the base 1 and is used to drive the drive block 101 to slide in the sliding groove.

[0039] The floating block 3 is located directly above the sliding groove. The lower end face of the floating block 3 is an inclined surface. The upper end face of the driving block 101 is an inclined surface that matches the lower end face of the floating block 3. When the telescopic device 2 drives the driving block 101 to insert below the floating block 3, the floating block 3 rises. When the telescopic device 2 drives the driving block 101 away from below the floating block 3, the floating block 3 falls.

[0040] It should also be noted that the application of the anti-gravity tilting mechanism described above in stamping dies greatly improves the operating efficiency of the die and the stability of material handling. Each float block 3 is correspondingly set in the positioning area of ​​the lower die, ensuring accurate positioning of the workpiece during the stamping process. When the telescopic device 2 drives the drive block 101 to insert below the float block 3, the float block 3 rises due to the force, pulling the workpiece up with it, thus achieving stable lifting of the workpiece. When the telescopic device 2 drives the drive block 101 away from below the float block 3, the float block 3 naturally descends under the action of gravity, releasing the workpiece and facilitating subsequent stamping operations.

[0041] For example, the drive block 101 is further provided with a buffer layer 4 on the end face facing the telescopic device 2.

[0042] It should also be noted that the buffer layer 4 serves to protect the drive block 101 and the telescopic device 2, preventing damage caused by direct impact.

[0043] For example, a first guide plate 5 is provided on the lower end inclined surface of the floating block 3, and a second guide plate 6 is provided on the upper end inclined surface of the drive block 101.

[0044] For example, a plurality of third guide slides 7 are provided on the side wall of the floating block 3, and the third guide slides 7 are arranged around the floating block 3.

[0045] It should also be noted that the arrangement of the first guide plate 5, the second guide plate 6 and the third guide plate 7 not only reduces the friction between the floating block 3 and the drive block 101, but also improves the sliding efficiency between the two, making the lifting and lowering of the floating block 3 smoother.

[0046] For example, the telescopic device 2 is a cylinder, and the piston rod end of the telescopic device 2 is connected to the drive block 101.

[0047] It should also be noted that the cylinder, as a power source, can provide stable and controllable driving force. By adjusting the cylinder's intake and exhaust volume, the extension and retraction speed of the piston rod can be precisely controlled, thereby achieving precise control over the lifting speed and position of the drive block 101 and the floating block 3. The cylinder structure is relatively simple, easy to install and maintain. Compared with other complex drive mechanisms, the cylinder has higher reliability and durability, reducing the mold's failure rate and maintenance costs.

[0048] Furthermore, the cylinder can be integrated with sensors and control systems to achieve automated control and monitoring. For example, position sensors, pressure sensors, etc., can be installed to monitor the cylinder's motion status and load in real time, and adjust the cylinder's operating parameters as needed.

[0049] For example, a fourth guide plate 8 is provided on the side of the drive block 101 that contacts the sliding groove.

[0050] It should also be noted that the purpose of setting the fourth guide plate 8 is to reduce the friction between the driving block 101 and the contact side of the sliding groove, and to improve the sliding efficiency between the two, so that the movement of the driving block 101 is smoother.

[0051] For example, the buffer layer 4 is polyurethane.

[0052] It should also be noted that the polyurethane buffer layer 4 has good elasticity and wear resistance, which can effectively absorb impact energy and ensure the long-term performance of the mold.

[0053] For example, the first guide plate 5, the second guide plate 6, the third guide plate 7 and the fourth guide plate 8 are all made of plastic.

[0054] It should also be noted that plastic guide plates are lighter and easier to carry and move than metal or wooden guide plates. Plastics are also cheaper to manufacture, and the types of plastics include ABS plastic, polycarbonate plastic, and polyurethane plastic.

[0055] For example, the outer surfaces of the first guide plate 5, the second guide plate 6, the third guide plate 7, and the fourth guide plate 8 are provided with a lubricating coating.

[0056] It should also be noted that the lubricating coating on the first guide plate 5, the second guide plate 6 and the third guide plate 7 further reduces friction, extends the service life of the guide plates, and ensures the continuous and stable operation of the mold.

[0057] Furthermore, the lubricating coating used, such as a graphite + copper guide plate, achieves lubrication by embedding graphite particles in a copper substrate and utilizing the extremely low coefficient of friction and self-lubricating properties of graphite. This coating can maintain a low coefficient of friction without the need for external lubricating oil, significantly improving the life of the guide plate. Alternatively, it can be prepared using water-soluble additives, imported antioxidant lubricants, antioxidant additives, graphite, boron nitride, and other materials, forming a very strong protective film on the lubricated surface such as the guide plate, providing high-temperature resistance and oxidation resistance while achieving stable low-load friction.

[0058] For example, a stamping die includes a lower die, the upper surface of which is provided with a plurality of positioning areas, and a plurality of the aforementioned anti-gravity tilting mechanisms are also provided inside the lower die, each of the anti-gravity tilting mechanisms corresponding to one of the positioning areas, and each of the floating material blocks 3 being located within the corresponding positioning area.

[0059] It should also be noted that during use, when the robotic arm picks up a part and places it into the lower mold, the placement process is guided by positioning fixtures and positioning holes to ensure the part is placed in the correct position. After the product is placed, the telescopic device 2 in the mold drives the drive block 101 to slide within the sliding groove. When the telescopic device 2 drives the drive block 101 away from below the floating block 3, the floating block 3 descends, preventing interference between the floating block and the part sheet. When the stamping machine moves downward and the first forming operation is completed, when the telescopic device 2 drives the drive block 101 to insert below the floating block 3, the floating block 3 rises, simultaneously ejecting the part.

[0060] In one embodiment, a lifting hole may be provided below the base 1, the lifting hole being connected to the sliding groove, and a lifting cylinder is provided below the base 1, the piston rod of which can extend upward from the lifting hole to lift the lower end of the floating block 3.

[0061] In summary, the anti-gravity tilting mechanism of this utility model allows the floating block 3 to rise and fall with the extension and retraction of the telescopic device 2, enabling it to adapt to the shape and center of gravity of the part. This effectively solves the problem of misalignment caused by an unstable center of gravity during the stamping process. This improvement not only enhances the stability of the part and production efficiency but also strengthens the protection of the mold and the stamping accuracy.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
