Side buckle type aluminum parting strip for hollow glass

Abstract

The invention discloses a side buckling type aluminum parting strip for hollow glass. The aluminum parting strip is formed by processing an aluminum strip through rolling of a forming die wheel set and straightening of a plurality of groups of press wheels in the front-back direction and left-right direction, the section outline is changed into a rectangular frame from a straight line shape, the left side edge and the right side edge of the aluminum strip are provided with concave-convex shapes, and the concave-convex shapes of the left side edge and the right side edge are distributed in a staggered mode. The aluminum parting strip is formed by buckling the concave-convex shapes of the aluminum strip at the joint of two adjacent faces through engaging, a row of vent holes are formed in one buckling face, and the other three faces are airtight. The aluminum parting strip is molded through rolling and straightening through the forming die wheel set, and is formed by side buckling of theconcave-convex shapes through engaging, the structure is firm, welding forming of a high-frequency welding machine is not needed, the vent holes are also formed through rolling of the mold wheels, noadditional vent hole is needed, a main isolation face is not welded, the phenomena of cracking, welding leakage and air leakage of welded junctions are avoided, the sealing performance of the aluminum parting strip is guaranteed, and the service life of the hollow glass is prolonged.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a side buckle-type aluminum spacer for insulating glass. Background technique [0002] Aluminum spacer is one of the necessary materials for making insulating glass, and its quality is directly related to the use effect, service life and heat insulation function of insulating glass. The aluminum spacer is made of aluminum strip through the mold rolling-punching-rolling-high-frequency welding-burring-rolling shaping-cutting-binding packaging-finished product, transported to the glass processing enterprise, and then the aluminum spacer is plugged , Bending, filling with molecular sieves, and then pasting in two pieces of glass, and then applying secondary sealant to make insulating glass. [0003] Existing aluminum spacer is to use the roll-shaped aluminum strip to be rolled into a mouth shape by the mold wheel, and then weld the interface with a high-frequency welding ma...

Problems solved by technology

[0003] Existing aluminum spacer is to use the roll-shaped aluminum strip to be rolled into a mouth shape by the mold wheel, and then weld the interface with a high-frequency welding machine, and then use the mold wheel to roll and shape it again, forming a straight line of mouth-shaped aluminum strip. The spacer is then cut according to a fixed length (usually 5 meters), bound and then packed in a carton to form a finished product with a length of 5 meters, a width of 0.2 meters and a height of 0.2 meters. The process is cumbersome, and the formed aluminum spacers cannot be bent. Packed according to the length of the fixed length, the products of such a length are easily deformed and scattered in cartons during transportation, which increases logistics costs and scrap rates; moreover, this kind of aluminum spacer welded by a high-frequency welder will burst at the welding joint and air leakage, which will affect the effect of molecular sieve, especially the welding joint is the only metal barrier to cut off the air inside and outside the insulating glass, which is prone to poor sealing, which will eventually affect the quality of insulating glass
