Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending structure technology, specifically a bending structure for metal sheets. Background Technology
[0002] Bending metal sheets can significantly improve their rigidity and stability. For example, after folding and bending aluminum panels, their rigidity can be increased, improving overall stability and reducing the possibility of deformation. In addition, bent metal sheets are more robust and durable under stress. Bending can also create various lines and shapes in metal sheets, thereby enhancing the aesthetics and artistry of the product. For example, bending aluminum sheets can create various lines, improving the visual appeal and artistic quality of the product.
[0003] For example, the metal sheet bending structure disclosed in the authorization announcement number CN221734495U includes a base, a pair of sliding blocks, a pair of clamping components, a bending placement platform, and a bending part. The base is provided with a sliding mounting groove, and the two sliding blocks are fitted and installed in the sliding mounting groove and slide with the sliding mounting groove. The two clamping components are respectively disposed on the two sliding blocks. The bending placement platform is disposed on the base and located between the two clamping components. The bending part is fitted and disposed above the bending placement platform. The clamping components include a support mounting block and a movable mounting block. The bottom of the support mounting block is connected to the sliding block, and the top of the support mounting block is provided with a placement plane. The movable mounting block is disposed above the placement plane and is connected at one end by a pair of fixing bolts.
[0004] Although it eliminates the need for operators to hold the metal plate during the bending process, it solves the problem that current bending structures pose certain dangers and can easily cause injury to operators and endanger their health because they require operators to hold and fix them.
[0005] However, this does not solve the problem that existing bending structures are generally not conducive to convenient rotation and replacement of different molds for bending processing, and are not convenient for quick switching between multiple sets of different molds. This affects the versatility of the bending structure for bending metal sheets, and makes it difficult to quickly place and clamp the metal sheets, which greatly affects the stability of the metal sheets during bending and the efficiency of the bending structure.
