The sliding assembly includes a threaded rod 3, and the threaded rod 3 can slide by squeezing the support frame 1 through the thread when rotating. The outer thread of the threaded rod 3 is threadedly connected to the right part of the support frame 1, and the threaded rod 3 is limited by the support frame 1 and can only rotate. The lower part of the support frame 1 is slidably connected to a bracket 2, and the bracket 2 can keep the overall device fixed. The upper part of the bracket 2 is fixedly connected to a T-block 13, and the bracket 2 keeps the T-block 13 fixed, and the outer part of the T-block 13 is slidably connected to the inner part of the support frame 1. The T-block 13 limits the support frame 1 to slide horizontally only within a fixed distance. The internal rotation of the bracket 2 is connected with a screw assembly, and the screw assembly includes a screw lever 9. The rotation of the screw lever 9 can make the two sets of sliding blocks 7 slide to adjust the size between the clamping blocks 6. The external thread of the screw lever 9 is connected with the sliding block 7. The sliding of the sliding block 7 can drive the clamping block 6 to slide. The external sliding of the sliding block 7 is provided with a long rod 8. The long rod 8 limits the sliding block 7 from rotating. When the screw lever 9 rotates, the sliding block 7 can only slide under compression. The two ends of the screw lever 9 are rotatably connected to the inside of the bracket 2, and the two ends of the long rod 8 are fixedly connected to the inside of the bracket 2. The bracket 2 keeps the screw lever 9 and the long rod 8 level.

[0025] See also Figure 1-Figure 3The upper part of the lead screw assembly is fixedly connected with a clamping assembly, which can clamp the sheet metal part. The right part of the lead screw assembly is slidably connected with a clamping block 4, which is square and can limit the wire lever 9 from rotating. The outside and inside of the clamping block 4 are respectively slidably connected to the inside of the bracket 2 and the wire lever 9. The bracket 2 has a polygonal groove inside, which can limit the rotation of the clamping block 4. The left part of the clamping block 4 is fixed with a square block, which slides inside the wire lever 9, so that the wire lever 9 can move with the clamping block 4. Together, they are restricted from rotating. The right part of the clamping block 4 is elastically connected to the right part of the screw assembly through a spring 18. The spring 18 can keep the clamping block 4 fixed inside the polygonal groove. One end of the spring 18 is fixedly connected to the inside of the clamping block 4, and the other end of the spring 18 is fixedly connected to the right part of the wire lever 9. The spring 18 is subjected to the pulling force of the wire lever 9 to keep the clamping block 4 in a state of being pulled. The right part of the clamping block 4 is fixedly connected with a sliding handle 12, which can facilitate the sliding out of the clamping block 4.

[0026] See also Figure 1-Figure 3 The side end of the clamping block 4 contacts with a stopper 10, and the stopper 10 is rectangular, which can block the clamping block 4 from sliding into the polygonal groove, so that it can rotate with the wire lever 9. The outside of the stopper 10 is respectively connected to the side ends of the bracket 2 and the clamping block 4, and the inside of the stopper 10 is slidably connected with a fixing rod 5, and the fixing rod 5 can keep the stopper 10 from sliding vertically within a fixed distance, and the left part of the fixing rod 5 slides inside the bracket 2, and the bracket 2 limits the fixing rod 5 to only slide. The fixing rod 5 is provided with two groups, and the side ends of the two groups of fixing rods 5 are elastically connected by spring three 17. The spring three 17 can keep the stopper 10 from sliding to a position in contact with the left part of the clamping block 4, so that it cannot slide in, and the clamping block 6 can quickly slide to a suitable position for convenient use.

The two ends of the fixing column 11 are fixedly connected to the inside of the bracket 2.

[0027] See also Figure 2-Figure 4The clamping assembly includes a fixed sleeve 15, and a through groove is provided at the side end of the fixed sleeve 15, so that the sliding column 14 will not rotate. The lower part of the fixed sleeve 15 is fixedly connected to the upper part of the sliding block 7, and the sliding block 7 can drive the fixed sleeve 15 to slide so that the clamping block 6 can slide to a suitable distance. The interior of the fixed sleeve 15 is elastically connected to the sliding column 14 through the spring 2 16, and the spring 2 16 can keep the sliding column 14 from sliding up to the upper end of the support frame 1. One end of the spring 2 16 is fixedly connected to the interior of the fixed sleeve 15, and the other end of the spring 2 16 is fixedly connected to the bottom of the sliding column 14. The spring 2 16 keeps the sliding column 14 in a state of squeezing the sliding column 14. The upper end of the sliding column 14 is fixedly connected to the clamping block 6, and the clamping block 6 is L-shaped. The clamping block 6 can keep the sheet metal from rotating during bending, resulting in bending failure.

[0028] Working principle: Slide the sliding handle 12, the sliding handle 12 drives the clamping block 4 to slide out of the polygonal groove and pull the spring 18. At this time, the spring 3 17 pulls the fixed rod 5 to slide toward the middle, and the fixed rod 5 drives the stopper 10 to slide toward the middle until it contacts the left part of the clamping block 4. Then rotate the threaded rod 3, and the threaded extrusion support frame 1 of the threaded rod 3 slides to adjust the gap to a suitable position. Place one end of the sheet metal on the clamping block 6 and then slide the clamping block 6 at the other end. The clamping block 6 drives the sliding column 14 to slide, and the sliding column 14 drives the fixed sleeve 15 to slide. The fixed sleeve 15 drives the sliding block 7 to slide, the sliding block 7 drives the wire lever 9 to rotate, and the wire lever 9 drives the clamping block 4 to rotate. After adjusting the distance, both ends of the sheet metal are placed on the clamping block 6, and the fixing rod 5 is slid upward and downward to pull the spring three 17. At this time, the clamping block 4 slides into the polygonal groove under the pulling force of the spring one 18 to keep the wire lever 9 fixed. At this time, the sliding block 7 is fixed, so that the clamping block 6 no longer slides, and the bending machine performs bending. The sheet metal squeezes the clamping block 6 to slide downward, and the clamping block 6 drives the sliding column 14 to slide downward to squeeze the spring two 16.
