The sheet metal body 2 is placed on the mold 1, and the hydraulic rod 301 is started, so that the telescopic end of the hydraulic rod 301 drives the bending block 3 to move downward, thereby squeezing the sheet metal body 2 to bend.

[0033] Reference Figure 1 and Figure 2 A positioning structure 4 is provided on the mold 1 for fixing the sheet metal body 2. The positioning structure 4 includes a baffle 5 installed on the mold 1, two limit plates 403 located on the mold 1, and a positioning plate 405 located on the mold 1. One end of the sheet metal body 2 is pressed against one side of the baffle 5, and the other two sides of the sheet metal body 2 are in contact with the limit plates 403, and the positioning plates 405 are used to limit and fix the sheet metal body 2.

[0034] A support plate 401 is installed on the mold 1, and a first electric telescopic rod 402 is installed on the support plate 401. A limit plate 403 is installed at the telescopic end of the first electric telescopic rod 402. According to the width of the sheet metal body 2, the first electric telescopic rod 402 is started so that its telescopic end drives the two limit plates 403 to move, which is used to position the sheet metal body 2.

[0035] A second electric telescopic rod 404 is installed on the mold 1, and a positioning plate 405 is installed at the telescopic end of the second electric telescopic rod 404. By starting the second electric telescopic rod 404, it drives the positioning plate 405 to move, which is used to limit the sheet metal body 2.

[0036] Reference Figure 1-4 A lubrication structure 6 is provided on the bending block 3, and the lubrication structure 6 includes an annular groove 601 opened on the bending block 3 and an oil tank 602 installed on the bending block 3, an oil outlet pipe 603 is connected to the oil tank 602, and the bending block 3 is provided with a plurality of oil outlet holes 604 interconnected through the annular groove 601, one end of the oil outlet pipe 603 is connected to the oil outlet hole 604, and the bending block 3 is clamped with a sponge ring 605 through the annular groove 601, and the lubricating oil in the oil tank 602 enters the oil outlet hole 604 through the oil outlet pipe 603, and then is discharged into the annular groove 601 through the oil outlet hole 604, thereby soaking the sponge ring 605.

[0037] An oil groove 611 is provided on the limit plate 403, and a hose 608 is connected to the oil tank 602. One end of the hose 608 is connected to a transverse pipe 609, and the transverse pipe 609 is connected to a lower oil pipe 610. One end of the lower oil pipe 610 passes through the inner wall of the limit plate 403 and is connected to the oil groove 611. The limit plate 403 is clamped with a sponge strip 612 through the oil groove 611. The lubricating oil in the oil tank 602 enters the transverse pipe 609 through the hose 608, and then enters the lower oil pipe 610 through the transverse pipe 609, and then enters the oil groove 611 through the lower oil pipe 610, and finally soaks the sponge strip 612.

[0038] During the movement of the bending block 3, lubricating oil is applied to one side of the baffle 5, the opposite side of the two limit plates 403, and one side of the positioning plate 405, and then the sheet metal body 2 is placed on the mold 1. At this time, when the bending block 3 subsequently bends the sheet metal body 2, the wear on the sheet metal body 2 is minimized, and the bending block 3 that moves up and down can apply lubricating oil to one side of the baffle 5, the opposite side of the two limit plates 403, and one side of the positioning plate 405 for multiple times, which is used for lubrication during batch processing.

The hose 608 passes through the inner side of the support ring 703. When the bending block 3 moves downward, the support rod 701 cooperates with the spring 702 and the support ring 703 to pull the hose 608, and try to avoid the hose 608 from being squeezed between the bending block 3 and the sheet metal body 2, which helps to protect the hose 608.

[0041] Working principle:

[0042] In the sheet metal bending device, the lubricating oil in the oil tank 602 enters the oil outlet hole 604 through the oil outlet pipe 603, and then is discharged into the annular groove 601 through the oil outlet hole 604, thereby soaking the sponge ring 605. The lubricating oil in the oil tank 602 enters the cross pipe 609 through the hose 608, and then enters the lower oil pipe 610 through the cross pipe 609, and then enters the oil tank 611 through the lower oil pipe 610, and finally soaks the sponge strip 612. During the movement of the bending block 3, one side of the baffle 5 is moved. Lubricating oil is applied to the side of the baffle 5, the opposite side of the two limit plates 403 and the side of the positioning plate 405, and then the sheet metal body 2 is placed on the mold 1. At this time, when the subsequent bending block 3 bends the sheet metal body 2, the wear of the sheet metal body 2 is minimized, and the bending block 3 that moves up and down can apply lubricating oil to one side of the baffle 5, the opposite side of the two limit plates 403 and the side of the positioning plate 405 for multiple times, which is used for lubrication during batch processing.

[0043] In the sheet metal bending device, when the bending block 3 moves downward, the support rod 701 cooperates with the spring 702 and the support ring 703 to pull the hose 608, and try to avoid the hose 608 being squeezed between the bending block 3 and the sheet metal body 2, which helps to protect the hose 608.
