Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0028] refer to Figures 1-5 A bending machine with adjustable feed depth includes: a worktable 1, a frame 2 fixed on the upper side of the worktable 1, a bending device 3 provided on the inner side of the frame 2, the bending device 3 including a bending component 31 fixed to the top of the frame 2, and a bending component 32 provided on the lower side of the bending component 31.

[0029] The bending component 32 includes a housing 321 fixed to the upper side of the workbench 1 and a support block 322 fixed to the upper side of the workbench 1 by screws. A gear 323 is connected to the inner side of the housing 321 by a key. A connecting plate 324 is slidably attached to one side of the housing 321. A rack 325 is provided on the outer side of the connecting plate 324. A sliding plate 326 is fixed to the top of the connecting plate 324. The rack 325 is meshed with the inner side of the gear 323.

[0030] The second bending component 32 includes a housing 321 that is securely mounted on the upper side of the worktable 1. A gear 323 is installed inside the housing via a key connection. A connecting plate 324 fits tightly against one side of the housing 321 and can slide smoothly along its surface. The sliding plate 326 fixed to its top is the same component as the sliding plate 326 in the first bending component 31, serving as a crucial force transmission link between the two bending components. A rack 325 on the outer side of the connecting plate 324 meshes with the gear 323, forming a mechanical transmission connection. A support block 322 is fastened to the upper side of the worktable 1 with screws and is positioned directly below the connecting plate 324. Its primary function is to limit the downward displacement of the connecting plate 324. Since an indirect force transmission path is established between the connecting plate 324 and the blade 312 through the sliding plate 326, when the support block 322 restricts the downward distance of the connecting plate 324, it also indirectly controls the downward distance of the blade 312, thereby realizing the control of the depth of cut.

[0031] The bending component 31 includes a cylinder 311. A blade 312 is fixed to the output end of the cylinder 311 via a piston rod. A connecting block 313 is fixed to one side of the blade 312.

[0032] A sliding plate 326 is fixed on one side of the connecting block 313.

[0033] The bending component 31 also includes a slide bar 314. The slide bar 314 is fixed to the lower side of the frame 2, and a slide plate 326 is slidably attached to the outer side wall of the slide bar 314.

[0034] The support block 322 is located directly below the connecting plate 324.

[0035] A storage box 4 is fixed on the upper side of the workbench 1.

[0036] Several support blocks 322 are placed inside the storage box 4.

[0037] The bending component 31 includes a cylinder 311 as a power drive element. Upon receiving a control signal, the piston inside the cylinder drives the blade 312, which is tightly connected to it, to move up and down in the vertical direction via the piston rod, thereby performing a bending operation on the workpiece placed on the worktable 1. The connecting block 313 securely connects the blade 312 to the piston rod. On the other hand, the sliding plate 326 fixed on one side of the connecting block works in conjunction with the sliding rod 314 fixed on the lower side of the frame 2 to form a high-precision guide structure. During the up and down movement of the blade 312, the sliding plate 326 can slide smoothly along the sliding rod 314. This constraint mechanism effectively limits the degree of freedom of movement of the blade 312, greatly reducing possible wobbling, deviation, and other unstable factors, thereby significantly improving the accuracy and consistency of the bending action.

[0038] Working principle: Please refer to Figures 1-5 As shown, the workbench 1 serves as the basic support structure, firmly fixed to the ground, providing a stable bearing surface for the entire bending operation, upon which the workpiece to be bent is placed. The frame 2 is installed above the workbench 1, constructing a stable structural framework for the bending device 3, providing solid structural stability and rigidity for the entire bending process, ensuring that the equipment maintains a stable and reliable state during operation.

[0039] The bending device 3 is the core component for realizing the bending function, with bending component 31 undertaking the main bending action. The cylinder 311, as the power drive element, upon receiving a control signal, drives the piston inside to move the blade 312, which is tightly connected to it, up and down in the vertical direction via the piston rod, thereby performing the bending operation on the workpiece placed on the worktable 1. The connecting block 313 securely connects the blade 312 to the piston rod, and its side-mounted sliding plate 326 works in conjunction with the sliding rod 314 fixed to the lower side of the frame 2 to form a high-precision guiding structure. During the up-and-down movement of the blade 312, the sliding plate 326 can smoothly slide along the sliding rod 314. This constraint mechanism effectively limits the degree of freedom of movement of the blade 312, greatly reducing potential instability factors such as wobbling and deviation, thus significantly improving the accuracy and consistency of the bending action.

[0040] The second bending component 32 includes a housing 321 that is securely mounted on the upper side of the worktable 1. A gear 323 is installed inside the housing via a key connection. A connecting plate 324 fits tightly against one side of the housing 321 and can slide smoothly along its surface. The sliding plate 326 fixed to its top is the same component as the sliding plate 326 in the first bending component 31, serving as a crucial force transmission link between the two bending components. A rack 325 on the outer side of the connecting plate 324 meshes with the gear 323, forming a mechanical transmission connection. A support block 322 is fastened to the upper side of the worktable 1 with screws and is positioned directly below the connecting plate 324. Its primary function is to limit the downward displacement of the connecting plate 324. Since an indirect force transmission path is established between the connecting plate 324 and the blade 312 through the sliding plate 326, when the support block 322 restricts the downward distance of the connecting plate 324, it also indirectly controls the downward distance of the blade 312, thereby achieving precise control of the depth of cut. The descent distance of the cylinder 311 is calculated in advance based on the support blocks 322 of different heights. When the support block 322 is replaced, the value of the descent distance of the cylinder 311 is changed. With their cooperation, the depth of cut can be kept stable and precise.

[0041] In addition, a storage box 4 is fixed on the upper side of the worktable 1, which stores support blocks 322 of various heights. In actual operation, the user can select a support block 322 with a suitable height from the storage box 4 according to the specific bending requirements of different workpieces, and accurately install it in the pre-set position on the worktable 1 using screws. Subsequently, when the cylinder 311 is activated and drives the blade 312 to move downwards, the blade 312 will gradually approach and eventually collide with the support block 322. Since the height of the support block 322 is determined during installation, the downward distance of the blade 312 (i.e., the depth of cut) will inevitably be limited by the height of the support block 322. In this way, the bending machine can precisely control the depth of cut, thereby flexibly meeting the diverse bending process requirements of various workpieces, effectively improving the applicability, flexibility, and processing accuracy of the equipment.
