[0002] A hydraulic bending machine is a metal sheet processing equipment driven by a hydraulic system, and it is widely used in sheet metal processing, machinery manufacturing, automotive industry and other fields.

[0003] Traditional hydraulic bending machines typically use a positioning plate installed behind the lower die, secured by bolts or welding. While this positioning method can provide positioning during sheet metal bending, it is difficult to adjust the distance when the sheet metal length needs to be adjusted, and the positioning plate is not easy to replace. This requires a significant amount of time to adjust or replace the positioning structure, reducing the bending efficiency of the sheet metal. Utility Model Content

By setting a positioning part, it can be adjusted according to different sizes of sheet metal to meet the needs of different dimensions. It can also be adjusted to the required positioning position according to different bending dimensions. This solves the problem that when the length of sheet metal needs to be adjusted, it is not easy to replace the positioning plate, which requires a lot of time to adjust or replace other positioning structures, thus reducing the efficiency of sheet metal bending.

[0053] One specific application of this embodiment is:

[0054] In use, adjust the position of the second limiting plate 323 according to the width of the sheet metal 34. Release the fixing of the second connecting bracket 324 by turning the threaded knob 325 counterclockwise. Then push the second limiting plate 323 to adjust its position. The fixing block 326 will slide on the slide rail 327, allowing the second limiting plate 323 to move linearly. Use a measuring tool to measure the distance between the first limiting plate 321 and the second limiting plate 323, and adjust it to a suitable size. After adjustment, turn the fixing block 326 clockwise to lock the second connecting bracket 324 in place. Then adjust the distance of the third limiting plate 331 according to the required bending size of the sheet metal 34. Release the fixing of the third limiting plate 331 by turning the threaded knob 335 counterclockwise. Then push the third limiting plate 331, allowing the third connecting bracket 332 to slide on the bracket 333. Adjust the distance of the third limiting plate 323... At position 331, use a measuring tool to measure the bending dimensions. After adjustment, turn the threaded knob 335 clockwise to fix the limiting plate 331, thus completing the dimension adjustment. This method can be adjusted according to different sizes of sheet metal 34 to meet different size requirements. It can also be adjusted to the required positioning position according to different bending dimensions. After the positioning adjustment is completed, place the sheet metal 34 on the lower mold 36. The support strip 35 is used to support the sheet metal 34 and prevent it from tilting. The limiting plate 321 and the limiting plate 323 position the sheet metal 34 on the left and right sides and make the back of the sheet metal 34 contact the limiting plate 331 to position the bending position. Then, the hydraulic cylinder 22 is started through the hydraulic system to drive the lifting seat 23 to move downward. The upper mold 231 and the lower mold 36 cooperate to bend the sheet metal 34.

[0055] When it is necessary to change to a different bending die, first remove the bolts on the lower die 36 to take it out. Then, insert the bottom of the new lower die 36 into the positioning block 2 361 for positioning, and then install bolts to fix it. By removing the bolts on the upper die 231, the upper die 231 can be taken out and replaced. Then, the new upper die 231 is inserted into the lifting seat 23 through the positioning block 1 232, and bolts are installed to fix the upper die 231. This method can quickly complete the fixing, and both the upper die 231 and the lower die 36 are positioned and installed, which can make the upper die 231 and the lower die 36 cooperate smoothly, which is convenient for subsequent bending work.
