Description

Five metals groove structure of roll forming

Technical Field

The utility model relates to a five metals groove technical field especially relates to a five metals groove structure of roll forming.

Background

The aluminum alloy doors and windows refer to the doors and windows which are made of aluminum alloy extruded sections serving as frames, stiles and sash materials, and are called aluminum alloy doors and windows for short. The bridge-cut-off aluminum is called as heat-insulating bridge-cut-off aluminum profile, and the heat-insulating aluminum alloy profile has more excellent performance than the common aluminum alloy profile, the bridge in the name of the bridge-cut-off aluminum refers to a cold and hot bridge in the meaning of materials, and the word of the letter 'cut-off' represents the action, namely the action of breaking the cold and hot bridge, at present, the bridge-cut-off aluminum alloy door and window has the advantages of attractive appearance, good sealing performance, light weight, convenience in installation and the like, and the bridge-cut-off aluminum alloy door and window is widely applied to various buildings and becomes the mainstream of door and window for buildings.

Because under the indoor outer size of aluminium alloy circumstances of confirming, under the circumstances that door and window section bar thickness specification is confirmed promptly, thermal-insulated strip size is big more, door and window's thermal-insulated thermal insulation performance is better, but because door and window hardware structure needs, at present a lot of section bars appear coming the shaping notch with thermal-insulated strip, as door and window five metals installation and hardware installation fixed mounting's notch, thermal-insulated strip intensity is weak, the notch that atress often made thermal-insulated strip during door and window switch damages, cause door and window five metals not hard up to drop, can not normally be used, to this problem the utility model provides a this structure, the section bar forms five metals groove structure through the roll-in deformation back, it is fixed to be used as the five metals installation, and is durable, has also kept thermal-insulated strip width size, has guaranteed door and window's thermal-insulated thermal insulation performance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a hardware groove structure formed by rolling.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a five metals groove structure of roll forming, includes the dovetail, first lug, the dovetail root, second lug and heat insulating strip, the dovetail is the opening form, can penetrate heat insulating strip in the dovetail, is provided with the second lug on the dovetail root, and first lug is located the lateral wall of dovetail upper end, and second lug and first lug form preforming five metals notch before the roll forming.

Preferably, after the heat insulation strip penetrates through the dovetail groove, an included angle a is formed between the second bump and the heat insulation strip.

Preferably, the root of the dovetail groove is rolled to clamp the dovetail groove into the heat insulation strip, and meanwhile, the second bump is forced to be close to the heat insulation strip, so that the included angle a is reduced.

Preferably, the second bump and the first bump form a final hardware mounting notch after the rolling is completed.

The utility model has the advantages that: this five metals groove structure, the second lug has angle change around the roll-in, and the second lug is aluminum alloy metal material, and the five metals is installed in this shaping notch, and intensity is high, and stability is good. And the width of the heat insulation strip can be kept as much as possible. The heat preservation and heat insulation performance of the door and window section bar is ensured.

fig. 2 is a schematic view of the cooperation between the pre-rolling structure and the heat insulating strip of the rolled hardware groove structure provided by the present invention;

fig. 3 is a schematic diagram of the rolled-in rear structure and the heat insulating strip of the rolled-in hardware groove structure of the present invention.

In the figure: 1 dovetail groove, 2 first lugs, 3 dovetail groove roots, 4 second lugs, 5 heat insulating strips, a contained angle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a five metals groove structure of roll forming, includes dovetail 1, first lug 2, dovetail root 3, second lug 4 and heat insulating strip 5, dovetail 1 is the opening form, can penetrate heat insulating strip 5 in dovetail 1, is provided with second lug 4 on the dovetail root 3, and first lug 2 is located the lateral wall of dovetail 1 upper end, and second lug 4 forms preforming five metals notch with first lug 2 before the roll forming.

After the heat insulation strips penetrate into the dovetail groove 1, an included angle a is formed between the second bump 4 and the heat insulation strips 5.

And rolling the root part 3 of the dovetail groove to clamp the dovetail groove 1 into the heat insulation strip 5, and meanwhile forcing the second bump 4 to be close to the heat insulation strip 5 to reduce the included angle a.

And when the rolling is finished, the second bump 4 and the first bump 2 form a final hardware mounting notch.

In this embodiment, this five metals groove structure, the second lug has angle change before and after the roll-in, and the second lug is aluminum alloy metal material, and the five metals is installed in this shaping notch, and intensity is high, and stability is good. And the width of the heat insulation strip can be kept as much as possible. The heat preservation and heat insulation performance of the door and window section bar is ensured.
