Aluminium alloy door window is decorated in the building indispensable, most can choose hangzhou aluminium alloy door in the family now, but most person hears aluminium alloy door only, do not understand to aluminium alloy door, hangzhou bo ao door window introduces aluminium alloy door production process craft step to everybody.
The support part of aluminium alloy door window is aluminium profile, the quality of aluminium profile still concerns the use safety of aluminium alloy door window service life. Ma youwei high-end aluminum alloy doors and Windows choose regular aluminum manufacturers produce high-quality aluminum ingots made of aluminum profile, with good tensile strength and yield, profile thickness strict implementation of "national standard" (up to 1.2mm wall thickness), profile standard can be customized according to the actual situation.
Specific aluminum alloy doors and Windows production process steps: aluminum alloy doors and Windows production process 1, broken material. Broken material, also known as "material", is the first process of aluminum alloy doors and Windows production, but also a key process. The main use of cutting equipment, material length should be based on the design requirements and reference to the door and window construction sample drawing to determine, the requirements of accurate cutting; Otherwise, the square of doors and Windows is difficult to ensure, the size error value should be controlled in 2mm range. Generally speaking, sliding door window breaks material appropriate to use right-angle cutting; 45° Angle cutting should be adopted for the broken materials of open doors and Windows. Other types should be based on the assembly to choose the cutting method. 2. Drilling. The frame fan assembly of window of aluminium alloy door USES screw connection commonly, no matter this is the assembly of horizontal and vertical lever, or of fittings fix, all need to be in corresponding position borehole. Profile drilling, can use a small bench drill or pistol type electric drill, the former because of the table, so can effectively ensure the accuracy of drilling position; The latter is easy to operate. Before drilling should be in accordance with the assembly requirements on the profile line positioning, drilling position is required to be accurate, the aperture is appropriate, can not be repeatedly changed in the profile surface drilling, because the hole once formed, it is difficult to repair. 3. Assembly. According to the requirements of the construction sample drawing, the sections are connected and assembled with screws through connecting parts. Aluminum alloy doors and Windows are assembled in three ways: 45° Angle butt joint, right Angle butt joint and vertical butt joint. The connection of horizontal and vertical bar, use special connection piece or aluminium Angle commonly, reoccupy screw, bolt or aluminium pull nail is fixed. The assembly quality of aluminum alloy doors and Windows shall conform to the following provisions:
(1) doors and Windows decoration surface should not be obvious damage. Every door window window is local abrasions, scratch, should not exceed the regulation of table 1. (2) doors and Windows on the adjacent components coloring surface should not be obvious color difference. (3) doors and Windows should be free of aluminum dust, burr, oil spots or other stains. Assembly connection should not spill adhesive. (4) door and window frame size deviation, should comply with the provisions of table 2. (5) the assembly gap of adjacent components of door and window frames and fans and the height difference of the same plane should conform to the provisions in table 3. 3, pay attention to the welding welding temperature 240~250℃, feeding pressure 0.3~0.35Mpa, clamping pressure 0.4~0.6Mpa, melting time 25~30 seconds. 4. Angle cleaning and Angle cleaning with imported Angle cleaning machine. After welding, the Angle cleaning can begin after 30 minutes of cooling. Install different types of tape strips on the clear corner frames, fans and glass battens as required. Frame and fan tape shall be on the upper handspike part of frame fan; The length of the strip should be about 10% longer to prevent the strip from shrinking. 5, the assembly of hardware plastic doors and Windows finished products by the frame and fan through the hardware assembly. Hardware assembly principle is: to have enough strength, the correct position, to meet the functions and easy to replace, hardware should be fixed in the inserted reinforced steel, hardware fixed can not be used with ordinary wood screws, should be used with 4mm self-tapping screw, hardware installation position should also strictly according to the standard. 6. The glass shall be installed in the place where the glass is to be installed. First, put the cut glass into the glass pad and place it on the pad. 7, finished product quality inspection plastic steel doors and Windows production processing, to carry out strict quality inspection. (1) appearance inspection: the surface of doors and Windows should be smooth and clean, free of bubbles and cracks, with uniform color, smooth welding, without obvious scars, impurities and other defects; (2) external dimension inspection: strictly control the quality of doors and Windows within the allowable deviation of national industry standards; (3) the assembly of sealing strip should be even, the interface should be tight, and there should be no delamination; (4) the layering assembly should be firm, the gap at the junction of corner position should be no more than 1mm, and two or more layering bars should not be used on the same side; (5) correct installation position, complete quantity and firm installation of hardware accessories; (6) welding strength shall be tested periodically during continuous production (mean value not less than 3000N, minimum value not less than 70% of the mean value).
