Doors and windows, stretch bending and pressboard workshop：
Address: middle section of South outer ring of Dashiqiao
Product parameters of white steel door and window and aluminum profile stretch bending
1, stretch bending radius
Minimum bending radius: aluminum profile is less than 8%.
Stainless steel profiles less than 30%
Maximum bending radius is not limited.
2. Tolerance of arc radius.
The radius is less than 1 meters, and the deviation is less than + 1mm.
The radius is greater than 1 meters, and the deviation is less than + 2mm.
3. Material calculation: the head end reserved chuck 300mm. Simple symmetrical small section section needs no test material, complicated section or big brea
The surface material needs to provide 1-2 test materials, and the material utilization rate is 95% according to the 6 meter profile.
4, roll bending decorative board width is 3 meters. Stainless steel stretch bending product parameters
Our factory mainly uses bending and bending products to bend all kinds of metal materials. Stretch bending is an advanced cold bending process. Its main features are as follows:
All sections can be bent.
Almost all sections of aluminum, steel, stainless steel, copper and other metal profiles and pipes can be bent.
Bending quality is good.
_After spraying, electrophoresis, electroplating, polishing, drawing and other materials can be directly bent, will not damage the material surface.
The profile of cavity and complex section can be formed at one time. When the relative bending radius is allowed, the inner wall will not wrinkle and the section will not be distorted.
Stretch bending can effectively eliminate the residual stress inside the material, and the product has good dimensional stability.
Because of the cold hardening of metal materials, the material can improve the comprehensive mechanical properties of materials after bending.
It can bend many curve shapes.
In addition to bending the conventional standard arc, it can also bend U-shaped, S-shaped, W-shaped, elliptical, parabolic, circular arc belt straight section, conical curve, a curve with a variety of radius and a series of complex curve shapes. Product parameters for stretch bending of iron profile
Maximum arc length: 12 meters.
The maximum length of one-time forming can reach 12 meters. For projects requiring longer arc length, the installation efficiency can be improved, the installation cost can be reduced, the materials can be saved and the engineering quality can be improved.
Maximum cold-formed cross section: 630mmx350mm
Bending radius: no restrictions on mechanical properties (elongation) allowed.
Strong bending ability
Stretch bending length: 12.5 meters.
There is no straight edge at both ends of the plate, and no waist drum is formed in the middle. It can also be made into special shapes such as straight edges, ellipses, cones, parabolas, etc. according to customer needs
Stretch bending product description
Keep the technological allowance at both ends.
In general, 150-200mm is maintained at each end, leaving 300-400mm at both ends. However, we need to discuss the length of the process allowance with our company in the following cases: thinner wall thickness, larger material section, less bending radius, complex bending shape, complex material section, etc.
