[0023] As Figures 1-4 shown, a markless bending die based on the flap bending technology includes a stamping head 1. The upper surface of the inner cavity of the stamping head 1 is fixedly connected with a positioning block 2. The inner cavity of the positioning block 2 is respectively movably connected with limiting rods 3. Springs 4 are sleeved on the surfaces of the limiting rods 3. Clamping blocks 5 are fixedly connected to the surfaces of the limiting rods 3. The lower parts of the clamping blocks 5 are in contact with the upper part of the inner cavity of the stamping head 1. A die assembly is arranged on the surface of the stamping head 1. On the opposite sides of the two limiting rods 3, push plates 6 are respectively fixedly connected. During work, when it is necessary to bend the flipping plate, the user presses the push plate 6, uses the push plate 6 to drive the limiting rod 3 to move, then uses the limiting rod 3 to drive the clamping block 5 to move, compresses the spring 4 with the clamping block 5, then connects the stamping head 1 with a stamping machine. The stamping machine is a prior art. Then, the spring 4 rebounds to drive the clamping block 5 to move, and then the clamping block 5 is connected with the stamping machine.

[0025] As Figures 1-2 shown, in some embodiments, the die assembly includes a support seat 7. A limiting frame 8 is hingedly connected to the inner cavity of the support seat 7. The limiting frame 8 is in contact with the surface of the stamping head 1. The lower part of the support seat 7 is fixedly connected with a mounting plate 9. Mounting grooves are respectively opened at the four corners of the surface of the mounting plate 9. During work, the user then places the flipping plate on the limiting frame 8 on the support seat 7, and then the stamping machine drives the stamping head 1 to move to stamp the flipping plate. When stamping, the limiting frame 8 moves, thereby preventing the problem of scratches on the surface of the flipping plate after stamping is completed.
