Manufacturing method of aluminum alloy doors and windows
1. Broken material. Broken material, also known as "blanking", is the first process and key process of making aluminum alloy doors and windows. Cutting equipment is mainly used for cutting materials, and the length of materials should be determined according to the design requirements and referring to the detailed drawing of door and window construction, which requires accurate cutting; Otherwise, it is difficult to guarantee the founder of doors and windows, the size error of broken material should be controlled within 2mm. Generally speaking, the broken materials of sliding doors and windows should be cut by right angle; The broken materials of flat doors and windows should be cut by 45 ° angle; Other types should be cut according to the assembly method.
2. Drilling. The frame fan assembly of aluminum alloy doors and windows generally adopts screw connection, so whether it is the assembly of horizontal and vertical bars or the fixing of accessories, it needs to be drilled at the corresponding position. Profile drilling can use small nail rhinestones or pistol electric drill. The former can effectively ensure the accuracy of drilling position due to its workbench; While the latter is because of convenient operation. Before drilling, the bullet line should be located on the profile according to the assembly requirements. The drilling position should be accurate and the aperture should be appropriate. It is not allowed to change the drilling repeatedly on the profile surface, because once the hole is formed, it is difficult to repair.
3. Assembly. Assemble the profile by connecting the connector with screws according to the requirements of construction detail drawing. The assembly methods of aluminum alloy doors and windows include 45 ° angle docking, corner butt joint and vertical docking. The connection of horizontal and vertical bars generally adopts special connectors or aluminum angle, and is fixed with screws, bolts or aluminum rivet nail.
The assembly quality of aluminum alloy doors and windows shall comply with the following provisions:
① There should be no obvious damage on the decorative surface of doors and windows. Local scratches and scratches on each door and window shall not exceed the provisions in Table 1.
② there should be no obvious chromatic aberration on the colored surface of adjacent components on doors and windows.
③ the surface of doors and windows should be free of aluminum chips, burrs, oil spots or other stains. There should be no overflowing adhesive at the assembly joint.
④ the size deviation of door and window frame shall conform to the provisions in table 2.
⑤ The Assembly clearance of adjacent components of door and window frame and fan and the height difference of the same plane shall conform to the provisions in Table 3.
