Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, and in particular to a small radius bending and cutting device. Background Technology

[0002] In the manufacturing process of doors and windows, beveling the profiles is a crucial step, as the cutting effect directly determines the appearance of the doors and windows. Currently, most panel cutting is done by workers using handheld cutting machines, a method that is overly simplistic and highly unstable. While existing clamping mechanisms have been improved, they are primarily designed for straight, elongated structures, requiring only clamping at the ends. Adjustment holes allow for changing the clamping position along a straight line, accommodating parts of varying lengths. However, for curved structures, due to varying radii, the clamping position cannot be adjusted along a straight line or arc. Therefore, a cutting device suitable for curved structures with different radii is needed. Utility Model Content

[0003] The small radius curved circle cutting device provided by this utility model enables rapid clamping of small radius curved circles, making the overall process more stable during cutting.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A small radius bending and cutting device includes a worktable, a base on the worktable, a cutting groove in the middle of the upper surface of the base, and a cutting blade movably mounted on the base;

[0006] The workbench is provided with a support column, and a support plate is rotatably installed on the upper end of the support column. A cylinder is installed on one end of the support plate, and the piston rod of the cylinder is connected to an upper pressure block facing downward. A lower pressure block is provided on the workbench, and the lower pressure block is flush with the base. The bent circle is placed on the lower pressure block and the base. When the cylinder is activated, the upper pressure block moves down and clamps the bent circle with the lower pressure block.

[0007] Further technology of this utility model:

[0008] Preferably, the support plate is provided with a waist-shaped hole, and the top of the support column is provided with a screw. The screw passes through the waist-shaped hole and is connected to a locking nut. The locking nut presses the support plate onto the support column.

[0009] Preferably, both the upper and lower pressure blocks are rubber blocks.

[0010] Preferably, the pressing block has a cylindrical structure and an eccentrically positioned shaft that connects to the worktable.

[0011] Preferably, the workbench is provided with a plurality of mounting holes arranged in a matrix, and the support columns and shafts are connected in the mounting holes.

[0012] The beneficial effects of this utility model are:

[0013] This utility model has a simple structure. The bent circle is placed on the lower pressure block and the base. When the cylinder is activated, the upper pressure block moves down and clamps the bent circle with the lower pressure block, achieving a more stable positioning. The cutting blade is then activated to cut the bent circle, avoiding instability during cutting. At the same time, the support plate can be rotated and adjusted on the support column and laterally adjusted along the waist-shaped hole. The two work together to achieve multi-angle adjustment. In addition, the lower pressure block can rotate along the eccentric axis to adjust the lower support position, which works in conjunction with the upper pressure block to accommodate bent circles of different radii.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1-2 A small radius bending and cutting device includes a worktable 10, a base 11 on the worktable 10, a cutting groove 12 in the middle of the upper surface of the base 11, and a cutting blade 13 movably mounted on the base 11.

[0020] In this embodiment, the base 11 is used to increase the cutting surface. On the one hand, the base 11 only needs to have a cutting groove 12, which reduces the need for changes to the worktable 10 and allows for position adjustments at any time. On the other hand, the cut segments can fall directly onto the worktable 10 due to gravity and separate from the curved body.

[0021] The workbench 10 is provided with a support column 14, and a support plate 15 is rotatably installed on the upper end of the support column 14. A cylinder 16 is installed on one end of the support plate 15. The piston rod of the cylinder 16 is connected to an upper pressure block 17 facing downward. A lower pressure block 18 is provided on the workbench 10. The lower pressure block 18 is flush with the base 11. The bent circle is placed on the lower pressure block 18 and the base 11. When the cylinder 16 is activated, the upper pressure block 17 moves down and clamps the bent circle with the lower pressure block 18.

[0022] It should be noted that there are multiple support columns 14 in the above structure, and the same number of corresponding pressing blocks 18 are provided. In this embodiment, three support columns 14 are provided to clamp the front, middle and rear parts of the curved circle.

[0023] The support plate 15 is provided with a waist-shaped hole 19, and the top of the support column 14 is provided with a screw 20. The screw 20 passes through the waist-shaped hole 19 and is connected to a locking nut 21. The locking nut 21 presses the support plate 15 onto the support column 14.

[0024] The pressing block 18 is a cylindrical structure, and a shaft 22 is provided at an eccentric position to connect with the worktable 10.

[0025] First, adjust the lower pressure block 18 (rotate the lower pressure block 18, and the lower pressure block 18 will adjust its position around the eccentric shaft 22). Place the bent circle on the lower pressure block 18, then loosen the locking nut 21, rotate and move the support plate 15 along the waist-shaped hole 19 to adjust the position of the support plate 15. The upper pressure block 17 and the lower pressure block 18 correspond vertically. Start the cylinder 16, and the upper pressure block 17 presses down and clamps the bent circle with the lower pressure block 18.

[0026] To further expand the adjustment range, the worktable 10 is provided with a number of mounting holes 23 arranged in a matrix, and the support column 14 and shaft 22 are connected in the mounting holes 23.

[0027] Furthermore, both the upper pressure block 17 and the lower pressure block 18 are rubber blocks. This provides high friction without causing wear on the curved surface.
