stretch bender Section bending machine

FEATURES OF THE MACHINE

The Machine Frame is Welded Steel Construction.

Heavy Duty and Rigid Construction

Machine can be Operated by Semi-Skilled or Unskilled Operator.

These machines can bend wide range of structural steel section,Flat bars, Solid Square or Round, Angle Iron (Leg In or Out), Round Tube, Square Tube, Rectangular Tubing.
Can be divided into rotary stretch bending machine and double rotary stretch bending machine and various special bending machine bending machine, such as shower rooms dedicated bending machine, bending machine, train the special elevator special bending machine.

Bending machine adopts full hydraulic control, simple operation, high production efficiency. All kinds of steel, cold-formed 500mm the following section tube, H type steel, I-beam, channel steel, angle iron, flat iron and aluminum, after bending arc perfect, high precision, stability

Well, the same type, and praise by customers.

Bending machine is mainly used for building the circular steel structure, tunnel supporting, carline, subway engineering, aluminum doors and windows, curtain wall, ceiling, round column skeleton, balcony handrail, shower room door, greenhouse, flower production line track, telephone booth, fitness equipment, display and other industries.

Bending product parameters

1, the bending radius

The minimum bending radius: Aluminum (R -R) /R ≤ 8%

Stainless steel (R -R) /R ≤ 30%

The maximum bending radius is not restricted

2, the bending radius tolerances:

Radius of less than 1 meters, per meter length error is less than ± 1mm

Radius of more than 1 meters, per meter length error is less than ± 2mm

3, material calculation: end reserved chuck 300mm. Simple symmetric small section without test material, complex section or fault

Surface material is required to provide 1-2 support test material, at the rate of 6 m profiles calculated as 95% using the material.

Stretch bending is an advanced cold bending process, the main features are as follows:

Can bending section

Aluminium, steel, stainless steel, copper and other metal materials, almost all sections of the pipe can be bent.

Bending of good quality

1. after spraying, electrophoresis, electroplating, polishing, drawing and other materials can be directly bending, does not damage the material surface.

2. cavity, complex section profile can be formed at one time. In the relative bending radius allowed, wall will not wrinkle, not distortion of cross section.

Can effectively eliminate the residual stress of tension and bending, the product has good dimensional stability.

3.because of the metal material cold hardening, material by bending, comprehensive mechanical properties can improve the material.

Can bend a variety of curve shape

In addition to bending standard arc, can also bend U shape, with a radius and a series of complex curve shape S shape, W shape, elliptic, parabolic, arc straight shape, conical curve, a curve.

Bending capacity

4. maximum bending arc length: 12 meters

Once forming the most up to 12 meters in length, the longer the arc length of the project can improve the installation efficiency, reduce the installation cost, save materials, improve the quality of the project.

5.maximum bending section: 500mmx350mm

6. bending radius: the material mechanical properties (elongation) permitting unrestricted.
