Description
Technical Field
The invention relates to the technical field of stretch bending processing, in particular to a high-precision double-rotating-arm stretch bending machine.
Background
Some large building profiles often need to be manufactured with a certain radian to achieve the integrity and the aesthetic property of the building frame. The metal sections such as various metal pipes, metal rods and the like can be bent by adopting a stretch bender, so that the metal sections have a certain radian. The existing stretch benders in the market are mainly divided into a rotary table type stretch benders and double-rotary-arm type stretch benders. The stretch bender is simple and convenient to operate, enables the processed section to be perfect in arc shape, and can improve the processing precision and the process consistency and improve the production efficiency.
The existing double-rotating-arm stretch bending machine is generally provided with a stretch bending template, rotating arms at two sides clamp two ends of a profile to rotate, and the profile is tightly attached to the profile of the stretch bending template to limit the stretch bending radian of the profile, so that the stretch bending of the profile is realized.
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.
In addition, the existing stretch bender has a single function, because the structural design of the working platform is simple, the arrangement of the clamps on the working platform is single, and the application range of the chuck to the section bars is single, the stretch bending of the existing stretch bender to the section bars such as steel and aluminum section bars is limited to the stretch bending of a certain radius section bar or the stretch bending of the section bars in a 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.
