I. Material breaking
Broken material, also known as "blanking", is the first process of making aluminum alloy doors and windows. According to the design requirements and referring to the construction details of doors and windows, use cutting equipment to accurately cut the length of materials. The size error of broken materials should be controlled within 2mm, otherwise the sealing quality of doors and windows is difficult to guarantee. Generally speaking, the broken materials of sliding doors and windows should be cut at right angles; The broken materials of flat doors and windows should be cut at a 45-degree angle; Other types should be cut according to the assembly method.
II. Drilling
The frame fan assembly of aluminum alloy doors and windows generally adopts screw connection. Therefore, whether it is the assembly of horizontal and vertical bars or the fixing of accessories, it is necessary to drill holes at corresponding positions. The drilling of profiles can adopt small nail rhinestones, which can effectively ensure the accuracy of drilling position due to the workbench. However, the use of pistol electric drill is convenient for operation. Before drilling, the elastic line should be located on the profile according to the assembly requirements, and the drilling position should be accurate and the aperture should be appropriate. Do not change the drilling holes on the profile surface repeatedly, because once the holes are formed, they are difficult to repair.
III. Assembly
Assemble the profiles with screws according to the requirements of construction detail drawing. The assembly methods of aluminum alloy doors and windows include 45-degree 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.
1. The size deviation of door frame, the Assembly gap of adjacent components of door frame and fan and the height difference of the same plane shall comply with relevant regulations.
2. The connection of door components should be firm, and the connection part should be sealed and waterproof with corrosion-resistant filling materials.
3. The installation position of door accessories is correct, complete and firm, and should play their respective roles. It has sufficient strength, flexible opening and closing without noise, and the accessories that bear repeated movements should be easily replaced in structure.
4. The quality of door glass, hardware, sealing and other accessories should be adapted to the quality level of the door.
5. After assembly, the gap between glass and inlaid groove should be ensured, and shock absorber pads should be installed in the main parts to buffer the impact of opening and closing isodynamic.
6. There should be no obvious damage on the decorative surface of the door.
7. There should be no obvious chromatic aberration on the colored surface of adjacent components on the door.
8. The surface of the door should not have aluminum chips, burrs, oil spots or other stains, and there should be no overflow glue outside the Assembly connection.
IV. Protection or packaging
After the semi-finished products are assembled and inspected, clean them up, cover the product certificate and package them, and then wait for the next step, such as income warehouse or outbound logistics.
