Description

Technical Field

[0001] The utility model relates to the technical field of bending positioning mechanisms, and specifically relates to a bending positioning mechanism with strong controllability. Background Technique

[0002] The bending process refers to that under the pressure of the upper die or the lower die of a bending machine, a metal sheet undergoes elastic deformation and plastic deformation in sequence to form a specific bending angle and shape. During the bending process, in order to ensure the bending accuracy, a bending positioning mechanism is usually required for auxiliary positioning to prevent the metal sheet from shifting and affecting the bending accuracy.

[0003] The bending positioning mechanism can ensure the position accuracy of the metal sheet during the bending process, but there are still certain problems: 1) Some metal sheets need to undergo multiple consecutive bending treatments. After the initial bending, the surface of the metal sheet is uneven, and the existing positioning mechanism is not convenient for clamping and positioning it; 2) One end of the metal sheet will rotate with the bending angle during the bending process, and the existing positioning mechanism cannot follow its rotation. Therefore, in view of the above current situation, there is an urgent need to develop a bending positioning mechanism with strong controllability to overcome the deficiencies in current practical applications and meet the current requirements.

[0027] Preferably, both the upper pressing roller 101 and the lower pressing roller 104 are hexagonal prism structures. Specifically, six groups of upper pressing dies 102 and lower pressing dies 105 with different shapes can be installed on their six faces to adapt to the clamping and positioning work after the material is bent.

[0028] Preferably, the inclination angle adjustment component 40 includes a sector frame 401, a mounting bracket 402, a motor b 403, and a gear 404.
