Description

Efficient semi-automatic stretch bending equipment Technical Field The invention relates to the field of intelligent manufacturing equipment, in particular to efficient semi-automatic stretch bending equipment.

Stretch bending equipment is an industrial equipment for realizing the process and for cold bending metal profiles. In the existing stretch bending process, a stretch bender is generally used for stretch bending of an aluminum profile, and the principle is that the aluminum profile is fixed in a fixed die and two bending dies, the fixed die is fixed, one bending die moves circularly along with the other bending die, so that the aluminum profile synchronously generates arc-shaped deformation, and the stretch bending purpose is achieved. For example, chinese utility model with publication No. CN108097754a discloses an aluminum profile stretch bending apparatus, which comprises a frame, a forming die apparatus, a rotating shaft, a guiding clamp, a pushing clamp, a follower compression section steel, a traction clamp and a rotating handle apparatus, wherein the forming die apparatus is mounted on the frame through the rotating shaft, the forming die apparatus is disc-shaped as a whole and rotates clockwise with the rotating shaft as a center, the guiding clamp and the traction clamp are respectively mounted and fixed on the frame along the rotating direction of the forming die apparatus and located at the 1/2 circumference two ends of the forming die apparatus, the pushing clamp is mounted on the frame and located at the outer side of the guiding clamp, the follower compression section steel is mounted and fixed on the pushing clamp and located between the guiding clamp and the pushing clamp, and the rotating handle apparatus is mounted and fixed on the forming die apparatus and is perpendicular to the connecting line between the guiding clamp and the traction clamp. However, in the practical use process, the stretch bender can only realize stretch bending work in a single direction, and can only stretch bending the whole aluminum profile into a ring shape aiming at the profile of the same model, multiple stretch bending operations are required after the stretch bending position of the profile is adjusted, and the degree of automation is low and the stretch bending efficiency is low.
