LJZW2020 Automatic Insulating Glass Aluminum Spacer Bar Bending Machine

LJZW2020 Automatic Insulating Glass Aluminum Spacer Bar Bending Machine 1

The angled aluminum frame is one of the reasons for the poor sealing of insulating glass; 

the main reason for the failure of angled insulating glass in the case of double sealing is usually improper handling of the four corners of the aluminum frame. Affects the sealing effect of insulating glass. With the improvement of corporate quality awareness and market competition, more and more companies are using aluminum strip bending machines to produce overall bent aluminum frames. In addition to fully automating the aluminum strip bending machine, glass deep processing practitioners use computers to input the shape, input size, input production quantity, input glue amount, etc. to the aluminum strip bending machine, as well as realize functions such as automatic splicing of aluminum strips, and innovate aluminum strips. The use functions of the bending machine are also placed in front of aluminum strip bending machine manufacturers.

It can be realized by bending the whole aluminum strip;

1. Install an argon gas filling hole on the aluminum strip bending machine.

Filling the insulating glass with argon gas is necessary for insulating glass buildings to save energy, reduce noise, lower the dew point, prevent the deformation of the insulating glass from causing the two pieces of glass to stick together, and prevent the oxidation of Low-E glass. As the number of companies that directly inflate air on insulating glass lines increases, the demand for companies that inflate air on aluminum frames is also increasing. This function can be added to the newly developed aluminum strip bending machine. Using an aluminum strip bending machine to drill air holes greatly improves the efficiency of drilling holes in the aluminum frame. 

2. Add the digital dimensioning function to the aluminum strip bending machine.

Nowadays, insulating glass production continues to be concentrated in large-scale insulating glass production enterprises. In large-scale production enterprises, insulating glass aluminum frames with similar sizes are prone to confusion when making insulating glass, and the accurate size cannot be found. As a result, the company's production is chaotic and quality is difficult to guarantee. When the aluminum strip bending machine bends the aluminum frame, printing the size and production date of the aluminum frame on the aluminum frame can avoid such problems and improve production efficiency. In addition, to completely solve the problem of aluminum strips affecting the sealing of insulating glass, special equipment for molecular sieve filling and aluminum strips is needed.

2. Introduction to supporting equipment for fully foldable aluminum frames.

Fully folded aluminum frame equipment includes a semi-automatic molecular sieve filling machine, automatic molecular sieve filling machine, semi-automatic aluminum strip bending machine, and fully automatic aluminum strip bending machine. The semi-automatic molecular sieve filling machine can punch the molecular sieve filling holes and fill the molecular sieve. In addition to flushing and filling molecular sieve holes, the fully automatic molecular sieve-filling machine can also automatically seal the molecular sieve-filling holes with glue. A semi-automatic aluminum strip bending machine can fold aluminum strips into rectangular shapes. In addition to folding aluminum bars into rectangles, the fully automatic aluminum bar bending machine can also bend aluminum bars into circular arcs and other arbitrary shapes.

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.
