LIJIANG Glass automatic insulating glass aluminum strip bending machine can complete the bending of an entire aluminum strip within 20 seconds at the fastest, that is to say, 4 times bending within 20 seconds to complete the bending of an entire aluminum strip, The size of 1m*1m insulating glass aluminum strip can be folded in about 10 seconds.

The bending clamp part of the automatic spacer bending machineThe bending clamp part of the automatic spacer bending machine 
In the production process of insulating glass, stainless steel composite warm edge strips are used more and more as insulating glass spacers. This kind of warm edge strip itself is relatively hard, and the bending angle of stainless steel composite warm edge strips is often encountered during processing. In the case of an ultra-wide section, it is difficult to completely solve the problem simply by increasing the pinch pressure of the spacer bending machine.

LIJIANG Glass can make the bending clamp part of the automatic spacer bending machine into separate parts, which are the red and green parts in the figure, and the red part is the corner part. We can design its plane position to be 10 wires higher than the green fixed part. , which is 0.1mm, this design can increase the force of the bending corner, reduce spring back, and effectively solve the problem of ultra-wide corners.

The glass fiber warm edge spacerThe glass fiber warm edge spacer
The glass fiber warm edge spacer itself does not contain any metal. The inner side of the warm edge contains glass fiber material, and the back is a non-metallic film. Its thermal performance is better than that of the impermeable steel composite warm edge and pure impermeable steel. Its excellent straight degree and strength degree ensure that the two glue depths between the three layers of glass are uniform, and the spacer is more straight and beautiful; the disadvantage is that the glass fiber material is generally relatively brittle. Bending glass fiber warm edge strips with ordinary bending machines will cause direct breakage of glass fiber warm edge strips. It must be heated and bent, and then cooled and shaped before it can be used.

The pure opaque steel stripsThe pure opaque steel strips
As a kind of rigid warm edge spacer, pure opaque steel strip has a weaker energy-saving effect than stainless steel composite warm edge strip and glass fiber warm edge strip, but it has obvious advantages in the use of fireproof insulating glass or large plate insulating glass, which puts forward new requirements for the spacer bending machine. Because of the high hardness of the impermeable steel, it is difficult for ordinary bending machines to form it at one time, so it is necessary to bend the pure impermeable steel spacer bar by multiple bending methods according to the different selection of impermeable steel materials.

How many sizes of aluminum bars can be bent by the widest equipment, and how many sizes of aluminum bars can be bent by the narrowest?

At present, the Automatic Insulating Glass Aluminum Spacer Bar Bending Machine has 4 troughs, which can generally be divided into four distributions: 6, 9, 12 and 12-27. The widest one can fold 27A aluminum strips, and the narrowest one can fold 6A aluminum strips.
