[0022] Some embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] See attached for details Figures 1 to 5 As shown, the multi-pass bending tube lettering tool described in the present invention includes a base plate 1, a lower positioning block 4, and an upper positioning block 7. The lower positioning block 4 is connected to the base plate 1, and the upper positioning block 7 is connected to the lower positioning block 4.

[0024] The base plate 1 is square, with equally spaced rectangular grooves 6 on its upper surface. The protrusions on either side of the rectangular grooves 6 are provided with equally spaced threaded holes 2. The lower positioning block 4 comprises a T-shaped portion 8 at its lower end and a cylindrical portion 10 at its upper end. The cylindrical portion 10 is located in the center of the T-shaped portion 8, and the bottom of the T-shaped portion 8 can be inserted into the rectangular groove 6 on the base plate 1. The T-shaped portion 8 is provided with waist-shaped holes 9, located on either side of the cylindrical portion 10. Connecting screws 3 are provided in these waist-shaped holes. The connecting screws 3 can be screwed into the threaded holes 2 on the base plate 1 to secure the lower positioning block 4 to the base plate 1. The waist-shaped holes 9 provide a certain amount of movement for the connection of the lower positioning block 4, making it easier for the connecting screws 3 to find the appropriate threaded hole 2.

The adjusting screw 13 facilitates the adjustment of the height and angle of the upper positioning block 7 and is suitable for clamping non-standard elbows with complex shapes.

[0026] To use this utility model: First, secure the base plate 1 to the cutting plotter worktable with M6 hexagon socket screws. Place the lower positioning block 4 on the base plate 1 and pre-tighten it with the connecting screws 3. Attach the upper positioning block 7 to the lower positioning block 4. Place the central straight section of the non-standard elbow 5 in the V-shaped groove on the upper positioning block 7. Install upper and lower positioning blocks on the other straight sections according to the direction of the non-standard elbow 5. After adjusting the position and angle, tighten the connecting screws 3 and tighten the lower positioning blocks 4.

[0027] The utility model has a simple structure, and assembly, clamping, and commissioning are relatively quick, greatly improving clamping efficiency. The lower positioning block 4 allows for modularization and mass production. Bends of different diameters can be made by simply replacing the existing upper positioning block 7. This clamp is suitable for clamping non-standard bends with multiple bends, as well as standard bends and straight pipes, offering excellent versatility. The lower positioning block 4 slides on the base plate 1, while the upper positioning block 7 rotates relative to the lower positioning block 4, providing high flexibility.
