Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending tool. Background Art

[0002] In the door manufacturing industry, bending machines are critical equipment for bending sheet materials (such as steel and aluminum alloy sheets) to design requirements. However, traditional bending machine designs often feature only one set of bending dies, consisting of a concave and convex die, fixed to the machine tool, enabling only one-way bending. This design presents significant limitations when faced with manufacturing requirements requiring bidirectional bending of sheet materials.

[0003] First, when bending the same sheet metal in two opposite directions, existing bending machines typically require manual intervention to remove the large sheet metal from the machine, flip it over, and then reposition it for the second bend. This process requires operators to endure heavy physical labor and faces the safety risk of the sheet metal slipping or colliding, posing a potential threat to their safety and health.

[0004] Secondly, manual sheet flipping not only adds a non-value-added step to the production process, but also significantly reduces production efficiency. Each flip consumes additional time and manpower, and it is also necessary to ensure the sheet is accurately positioned after flipping. This time-consuming and error-prone process not only extends production cycle time but also may lead to increased production costs.

[0005] Furthermore, manual operation inevitably leads to errors such as inaccurate positioning and deviations in bending angles. These issues not only lead to material waste and increased material costs, but can also affect the quality and precision of the final panels. In the door manufacturing industry, panel precision and dimensional stability are crucial to overall product performance and user satisfaction.

[0006] Finally, over-reliance on manual operations reduces the automation level of the production line, limiting the potential for increased production efficiency. With the transformation and upgrading of the manufacturing industry, automation and intelligentization have become the development trend in the door manufacturing industry. However, traditional bending machines lack flexible mold replacement mechanisms and automatic flipping functions, making it difficult to meet market demand for high-efficiency, high-precision sheet metal products.

[0007] In summary, existing bending machines have safety hazards, low production efficiency, increased material costs, and insufficient automation when dealing with complex bending tasks in the door manufacturing industry. An innovative solution is urgently needed to overcome these technical bottlenecks and improve the overall competitiveness and product quality of the door manufacturing industry.

The present invention may also be implemented or applied through different specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are merely illustrative of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] like Figure 1 As shown, in an embodiment of the present application, a tool rotation mechanism, a first tool 8 and a second tool 13 are included. The tool rotation mechanism includes a rotation unit and two drive units; the two drive units are arranged in parallel and spaced apart. Each drive unit includes a cylinder 1 and a guide shaft 3, and the cylinder 1 is connected to the rotation unit through the guide shaft 3. The rotation unit includes a rotation drive assembly, a rotation fixed shaft 7 and two rotation seats 6; the two rotation seats 6 are respectively connected to the two guide shafts 3 in a one-to-one correspondence. The two ends of the rotation fixed shaft 7 are respectively mounted on the two rotation seats 6. The rotation drive assembly is connected to one end of the rotation fixed shaft 7. The first tool 8 and the second tool 13 are both mounted on the rotation fixed shaft 7.

[0035] like Figures 1 to 3 As shown, in one possible embodiment, the drive unit further includes a fixed base 2, which is provided with a guide hole 2a. The guide shaft 3 is located within the guide hole 2a and slidably engages with the guide hole 2a. The guide hole 2a on the fixed base 2 is used to guide the guide shaft 3, ensuring the reliability and stability of the movement of the guide shaft 3.

[0036] like Figures 1 to 3 As shown, in a possible embodiment, the rotation drive assembly includes a drive motor 4 and a reducer 5, and the drive motor 4 is connected to one end of the rotating fixed shaft 7 through the reducer 5. By using the reducer 5, the speed of the drive motor 4 can be reduced.

[0037] like Figures 1 to 3As shown, in one possible embodiment, the tool rotation mechanism further includes a limiting unit, which includes a rotation limiting block 9 and two limiting slots 7a provided on the rotation fixing shaft 7. The rotation limiting block 9 is provided with a limiting protrusion 9a that corresponds to the limiting slots 7a. After the tool is switched, the piston rod of the cylinder 1 retracts, and the limiting slots 7a cooperate with the limiting protrusion 9a to limit and fix the tool.

[0038] like Figures 1 to 3 As shown, in a possible embodiment, the first tool 8 and the second tool 13 are installed at 90° on the rotating fixed shaft 7; and the first tool 8 is arranged opposite to one of the limiting grooves 7a, and the second tool 13 is arranged opposite to the other limiting groove 7a.

[0039] like Figure 2 and Figure 3 As shown, the bending machine includes a frame and a moving mechanism, wherein the frame includes an upper frame 11 and a lower frame 14. The moving mechanism includes a slider 10 and a slider driving unit. The slider 10 is mounted on the upper frame 11 so as to be able to slide up and down. The slider driving unit is connected to the slider 10 and is used to drive the slider 10 to move up and down relative to the upper frame 11.

[0040] Two sets of bending tools need to be installed on the bending machine, one set is installed on the slide 10 and the other set is installed on the lower frame 14.

[0041] The following description is made by taking a bending tool mounted on the slider 10 as an example:

[0042] The cylinder 1 and the guide shaft 3 are mounted on the slider 10 through the fixing seat 2. The rotation limit block 9 is mounted on the bottom end of the slider 10. When it is necessary to switch tools, the piston rods of the cylinder 1 on the left and right sides of the slider 10 are controlled to extend. While the piston rod of the cylinder 1 is extended, the rotating unit, the first tool 8 and the second tool 13 are pushed downward together, so that the limiting groove 7a is separated from the limiting protrusion 9a. When the rotating unit moves downward into place, the drive motor 4 is controlled to rotate in a preset direction, switching from the current tool to another tool (if the current tool is the first tool 8, then switch from the first tool 8 to the second tool 13; if the current tool is the second tool 13, then switch from the second tool 13 to the first tool 8). Then the piston rod of the cylinder 1 is controlled to retract. While the piston rod of the cylinder 1 retracts, the rotating unit, the first tool 8 and the second tool 13 are driven to move upward together. When the rotating unit moves upward into place, the limiting protrusion 9a on the rotating limiting block 9 is just stuck in the limiting groove 7a on the rotating fixed shaft 7, so that the limit is firm and there is no shaking, and it can continue to be used normally.

[0043] During use, when the current tool of one set of bending tools is the first tool 8 , the current tool of the other set of bending tools should be the second tool 13 , and the first tool 8 and the second tool 13 cooperate to achieve bending of the plate 15 .

[0044] like Figure 4 As shown, in a possible embodiment, when the plate 15 needs to be bent into a Z shape, the first bending is completed by first cooperating the second tool 13 among the bending tools installed on the slider 10 with the first tool 8 among the bending tools installed on the lower frame 14, and then the second tool 13 among the bending tools installed on the slider 10 is switched to the first tool 8, and the first tool 8 among the bending tools installed on the lower frame 14 is switched to the second tool 13, and then the second bending is completed by cooperating the first tool 8 and the second tool 13.

[0045] These are the preferred implementations of the present invention, but the implementations of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
