Bent hollow spacing bar shaping machine

Abstract

The invention creatively provides a bent hollow spacing bar shaping machine. The bent hollow spacing bar shaping machine comprises an upper pressing wheel capable of vertically moving and two lower pressing wheels which are relatively fixed to the base and located on the two sides of the upper pressing wheel respectively; and a middle section of the upper pressing wheel and middle sections of the lower pressing wheels are located in one vertical plane. By means of the bent hollow spacing bar shaping machine, spacing bars can be bent in advance, the radian of the spacing bars can coincide with the glass bend radian under the condition that no external force is borne, and therefore the coincidence between glass and the spacing bars is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment for building doors and windows, and in particular relates to a molding machine for bending spacers in the production process of curved insulating glass. Background technique [0002] With the continuous development of the construction industry, designers' pursuit of architectural art is also getting higher and higher. The proportion of curved insulating glass with a certain radian used in buildings is increasing, but the curved insulating glass is prone to air leakage, which makes the hollow failure problem has been plagued by people in the field. The reasons for such problems mainly include the inconsistency in the arc shape of the two pieces of synthetic hollow tempered (or hot-bent) glass, and the hard material of the spacer, which makes it difficult to bend in the width direction and cannot be well matched with the glass. [0003] The consistency of the arc of the glass is poor,...

Problems solved by technology

The proportion of curved insulating glass with a certain radian used in buildings is getting higher and higher, but the curved insulating glass is prone to air leakage, which makes the hollow failure problem has been plagued by people in the field

Except for the super spacer, the gas material has relatively high hardness, and the bending resistance in the width direction of the spacer is strong, so it is difficult to achieve a close fit (such as figure 2 )

At present, the bending technology of the spacer tends to cause that the spacer is not on the same plane after bending, and the flatness is poor

Although the super spacer is flexible, its desiccant content is at most about 30%, which is difficult to meet the requirements of insulating glass for desiccant water absorption

At the same time, its anti-extrusion ability is poor, and the glass will be flattened during the subsequent treatment of improving the fit (using large clips to improve the fit before the glue is solidified), which cannot meet the customer's requirements for the hollow layer. , affecting the overall thermal insulation performance of glass products
