The width of the dividing cutter is gradually reduced from inside to outside, so that the dividing cutter is in point contact with the stretch bending material when in division, the stretch bending material can be better divided, then the stretch bending material is gradually and completely divided, the deformation degree of the stretch bending material during division can be reduced, the maximum width of the dividing cutter is larger than the longitudinal height of the stretch bending material, and the dividing cutter can completely divide the stretch bending material.

Preferably, a waste box is fixedly arranged on the base and is positioned at the bottom of the cutting die. The waste bin is used for collecting the waste material that leads to the groove exhaust through the second, avoids the waste material to pile up in cutting apart the mould and leads to the motion to be obstructed, can avoid the pollution to the environment simultaneously.

Preferably, the base is provided with a plurality of punching structures, and the punching structures punch the stretch bending material in the stretch bending die. The structure of punching is to stretch bending material punch after the stretch bending material is accomplished the stretch bending and is stereotyped, and the structure of punching is current structure, the utility model discloses no longer carry out too much explanation, the position and the quantity of the structure of punching can change according to production and requirement.

Preferably, the number of the perforation structures is 4. The quantity of the structure of punching can change according to actual requirement, the utility model discloses use 4 structures of punching to explain as the example, 4 structures of punching are located the both sides of cutting apart the structure and symmetric distribution, can beat 4 holes to the stretch-bending material after the stretch-bending is accomplished like this.

Therefore, the utility model discloses a stretch bending mould that can cut apart possesses following advantage: multiple functional, can cut apart the material after the stretch bending into the material of two symmetries, punch the material after the stretch bending, can collect remaining waste material simultaneously, the result of use is stable.
