Analysis Of Characteristics And Requirements Of Stretching And Bending Process

What are the characteristics and requirements of stretching and bending processing technology? You know what? The staff of the stretching and bending processing factory will explain it to you. I hope it can help you.

1. The useful arc length of each curve should not exceed 180 degrees radian Angle under normal circumstances.

2, the so-called tensile bending is in the premise of prefabricated stretching to the profile, using rotation and through the mold to change the section deformation of the middle surface plastic deformation process.

3. About the quantity of data: In general, one or two copies should be added according to the practical quantity required by different sections, radius and arc length, so as to debug the mold. This backup does not take into account the amount of data that may be lost in transportation, processing, devices, and other links after data twists and turns.

4, the hardness of the data requirements: when the bending profile elongation is satisfied with the deformation requirements, should choose T5 status, China's standard for aluminum 8%; =t/R in 100% = (R outside -R inside) R inside 100% or To~T4 condition should be selected, of course, profile manufacturers are generally reluctant To generate T1~T4 condition profiles for customers.

5, data preparation, length: generally speaking, data preparation should be required to twists and turns and useful process of arc length, the sum is equal to 2.1 times of the width of the deformation, deformation width equal to the outer radius minus the inner radius, the length of data preparation = arc length + 2.1 t, of course, useful information detailed length can be according to the practical situation of the preparation of consideration, to save process part.

6, the profile appearance handling requirements: general can pick on anodic oxidation or winding coating processing, because there is no relative displacement between profiles when winding profiles and die, and therefore will not damage the material, if material winding process peeling coating because of lack of formation of the adhesion of coating, the lack of adhesion to improper pretreatment or heating and heating the main reason for the lack of time. Of course, in order to facilitate transportation and installation, should be appropriate to do external protection.

The above is the whole content of the characteristics and requirements of the stretching and bending process. If there is anything you do not know, you can communicate with our customer service, we sincerely serve you.
