[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, the segmented splicing bending die structure provided by the present invention is arranged on the bending machine base 1, and the segmented splicing bending die structure includes a segmented lower die strip 10 and a driving assembly 20. The segmented lower die strip 10 is movably arranged on the bending machine base 1, and the driving assembly 20 is arranged on the bending machine base 1 and connected to the segmented lower die strip 10. The driving assembly 20 can drive the segmented lower die strip 10 to be spliced or separated, and drive the segmented lower die strip 10 to separate during the loading and unloading process of the clamp, providing a clearance space for the clamp to enter or exit the bending machine to avoid collision, and drive the segmented lower die strip 10 to be spliced during the bending process, thereby completing the bending process. The segmented splicing bending die structure provided by the present invention can facilitate the clamp to enter or exit the bending machine, avoid collision between the clamp and the bending machine die strip, speed up the production rhythm, and improve production efficiency.

[0022] The segmented lower mold bar 10 includes a first mold bar 11 and a second mold bar 12, which are respectively arranged on both sides of the bending machine base 1. The bending machine base 1 is provided with a loading notch 2, which can be used for the clamp to move, providing a clearance space for the clamp to enter or exit the bending machine. The first mold bar 11 and the second mold bar 12 are respectively arranged on both sides of the loading notch. The first mold bar 11 and the second mold bar 12 are in a separated state during the loading and unloading process of the clamp, providing a clearance space for the clamp to enter or exit the bending machine to avoid collision. They are in a spliced state during the bending process, thereby cooperating with the upper mold bar of the bending machine to complete the bending process, thereby improving the reliability of the structure.

[0023] The first mold bar 11 is provided with a splicing hole 111, and the second mold bar 12 is provided with a splicing protrusion 121 adapted to the splicing hole 111. The splicing protrusion 121 is movably arranged in the splicing hole 111. When the first mold bar 11 and the second mold bar 12 are in a splicing state, the splicing protrusion 121 is stuck in the splicing hole 111, thereby enhancing the structural strength and stability of the first mold bar 11 and the second mold bar 12 after splicing.

[0024] The drive assembly 20 includes a drive cylinder 21, which includes a cylinder body 211 and a piston rod 212. The cylinder body 211 is arranged on the second mold bar 12. One end of the piston rod 212 is retractably arranged in the cylinder body 211. The other end of the piston rod 212 is provided with a fixed block 22. The fixed block 22 is arranged on the bending machine base 1. The drive cylinder 21 can be extended and retracted by the piston rod 212 to drive the second mold bar 12 to move, thereby causing the second mold bar 12 to move closer to or away from the first mold bar 11, so that the first mold bar 11 and the second mold bar 12 are separated or spliced, thereby providing good structural reliability. The two drive cylinders 21 are respectively arranged on both sides of the second mold bar 12, thereby further improving the reliability of the structure, ensuring the structural stability of the first mold bar 11 and the second mold bar 12 when spliced, improving the structural strength after the first mold bar 11 and the second mold bar 12 are spliced, and ensuring the normal operation of the bending process.

[0025] The segmented splicing bending die structure provided by the present invention also includes a support frame 30, which includes a first support frame 31 and a second support frame 32. The first support frame 31 and the second support frame 32 are both arranged on the bending machine base 1, and the first support frame 31 and the second support frame 32 are respectively located on both sides of the feeding notch 2. The first support frame 31 is provided with a first groove 311, the shape of which is adapted to the shape of the first mold bar 11, and the first mold bar 11 is arranged in the first groove 311; the second support frame 32 is provided with a second groove 321, the shape of which is adapted to the shape of the second mold bar 32, and the second mold bar 12 is movably arranged in the second groove 321. The second groove 321 can support the second mold bar 12 and can limit the second mold bar 12 during the splicing process, thereby ensuring a smooth splicing process of the first mold bar 11 and the second mold bar 12, thereby improving the reliability of the structure.

[0026] With the segmented splicing bending die structure provided by the present invention, during the sheet bending process, the clamp grips the sheet and moves on the guide rail. When the clamp enters the bending machine, the first mold bar 11 and the second mold bar 12 are in a separated state, the clamp jaws open, the bending machine suction gripper grabs the sheet, the clamp retreats through the feeding notch 2, the jaws close, and the next sheet is grabbed, thus avoiding the frequent opening and closing of the clamp jaws and speeding up the production cycle. During the bending process, the second mold bar 12 approaches the first mold bar 11, and the splicing protrusion 121 is clamped in the splicing hole 111, so that the first mold bar 11 and the second mold bar 12 are spliced, and the sheet bending process is completed in cooperation with the upper mold bar of the bending machine, thereby improving the reliability of the structure.
