The stretch bender is the main equipment for stretch bending of steel, aluminum profiles and other profiles.
The working platform is used as a main operating platform of the stretch bending machine and plays an important role in positioning, pressing and controlling deformation of the section bar in the stretch bending process. The existing stretch bender has a single function, because the structural design of the working platform is simple and the arrangement of the clamps on the working platform is single, the stretch bending of the existing stretch bender on the sectional materials such as steel, aluminum profiles and the like is limited to stretch bending of a certain radius sectional material or certain specification and model, and the application range is small. However, in practical application of stretch bending sectional materials, the types of the sectional materials to be used are very many, and in the practical operation process, the existing stretch bending machine cannot simultaneously perform stretch bending on most of the sectional materials.
At present, most of the section bar stretch bending processes in China need to enable the section bar to be tightly attached to the molded surface of a stretch bending template as much as possible so as to ensure the forming precision, and finally, external force is removed and materials are taken.
When the multi-section stretch bending is carried out on the section, the stretch bending template can be well attached to the stretch bending formed section in an ideal state. However, because the section includes plastic deformation and elastic deformation in the stretch bending process, the section can show a certain rebound property after bending is completed, when the section is continuously changed along with the bending angle, the joint position of the section is also continuously changed along the profile surface of the stretch bending template, when the section is subjected to multi-section stretch bending, because the bending process of the section is from the middle to the two ends, the section close to the middle is bent in place in the early stage, but because of the difference of the bending radians when the two ends are bent, the section generates a lever effect, the original bending result close to the middle section is damaged, and meanwhile, because the design of a working platform is unreasonable, a gap is formed between the section and the stretch bending template, the forming precision is influenced, the product cannot achieve the optimal forming effect, secondary shaping is required, and the production efficiency is low.
