Description

Technical Field

[0001] This utility model relates to the field of aluminum strip bending equipment, specifically a device for bending aluminum strips in insulating glass. Background Technology

[0002] In the production of insulated glass, aluminum strips (4×6 meters) are cut to the required length according to the glass size requirements. Desiccant is filled inside the strips, and four strips are connected into a rectangular frame using right-angle brackets. The two panes of glass are then fixed together using this frame, and sealant is applied between the panes. After 24 hours, the insulated glass unit is ready. The desiccant and sealant prevent moisture from seeping into the cavity between the glass panes. When there is a large temperature difference between the inside and outside, moisture will form condensation on the glass, affecting its usability. Because the four corners of the aluminum frame are connected by brackets, there are eight contact points between the brackets and the aluminum strips. These are the biggest potential leak points affecting the airtightness and lifespan of the insulated glass.

[0003] To address the aforementioned issues, a search revealed a Chinese patent with authorization announcement number CN2455401Y, which discloses a device for bending aluminum strips in insulating glass. The patent describes placing an aluminum strip in an aluminum strip placement groove, aligning it with a corner pin according to the required dimensions, holding the aluminum strip in the groove with one hand, and pushing the aluminum strip towards the corner pin with the other hand to completely fold the angled aluminum strip into the groove on the other right-angle side. Then, the entire aluminum strip is removed, and the strip is placed back into the placement groove according to the required dimensions until all four corners are folded, forming a rectangle. The excess aluminum strip is then sawn off at the intersections, and the interface ends are connected using a straight-pronged connector.

[0004] Although the above-mentioned device can bend aluminum strips, stress concentration occurs at the bend, resulting in an uneven bend and poor quality. Utility Model Content

[0025] As can be seen from the above, when using the device, the operator first holds the limiting seat 6 and inserts the positioning seat 9 at the top of the limiting seat 6 into the positioning groove 10 at the bottom of the drive frame 11. Then, using studs and nuts, the limiting seat 6 is fixed inside the drive frame 11. Next, the aluminum strip body 4 is inserted into the curved space formed between the limiting seat 6 and the curved wheel 2. Holding the handle 8, the operator drives the drive frame 11 and the connecting frame 14 to rotate. During the movement of the drive frame 11 and the connecting frame 14, the guide post 51 at the bottom of the drive frame 11 and the connecting frame 14 is slidably set inside the guide rail 5, which can limit the movement of the drive frame 11 and the connecting frame 14.
