[0102] Compared with the door body formed by bending a steel plate, the door body has the following advantages.

[0103] (1) The door leaf inner frame 101, the door leaf outer frame 102, the door frame body 200 and the decorative door sleeve 220 are made of aluminum profiles, which are convenient for extrusion forming or casting forming, and avoid the problems of inconvenient bending of the steel door leaf frame, long bending forming time, large error of the bending shape and angle and the like. The door leaf frame is divided into the inner frame 101 and the outer frame 102, which is convenient for forming and improves the installation efficiency and flexibility of the door panel.

[0104] (2) The inner frame 101 and the outer frame 102 are fixedly installed together through the frame positioning groove and the frame positioning block (not specifically shown in the figure), so as to improve the assembly efficiency. The inner frame 101 and the outer frame 102 are matched with the frame positioning groove and the frame positioning block, so that the assembly precision of the inner frame 101 and the outer frame 102 is high. The adoption of the aluminum profile door frame and the door sleeve greatly reduces the weight of the door frame and improves the convenience and safety of installation. The design of the corner code mounting groove 202 makes the insertion of the door frame corner code 210 more convenient and firm, and improves the overall stability of the door frame.

[0105] (3) The aluminum profile door frame, the door sleeve and the aluminum profile are precisely cut and assembled, the shape and angle of the cutting have higher precision, the controllability of the error is very high, and the bending error of the steel door leaf frame does not bring troubles to the subsequent welding assembly, installation and debugging, and also has a great influence on the quality of the whole product. The door leaf frame and the door leaf of the utility model have high product quality, and can still maintain the rectangular shape of 90° in the long-term use process.

[0106] (4) The steel door aluminum profile door frame, the door sleeve and the door leaf frame are bent in the process, and at least the following equipment is used: plate shearing machine, laser cutting machine (or plasma cutting machine), punching machine (or pressure machine), roll forming machine, bending machine, welding machine, assembly clamp and hoisting equipment (moving heavy steel parts).

[0107] (5) The time required for the whole process from the aluminum profile to the security door is only 8 to 12 days, which is relatively consistent with the customization of e-commerce.

[0108] (6) High plasticity and processing flexibility. Aluminum profiles have good plasticity and ductility, and can be processed into various complex and precise cross-sectional shapes through extrusion, stretching and other methods, meeting the various requirements of designers for door leaf appearance and performance. In addition, the processing process of aluminum profiles is relatively simple and low in cost. Although steel plate sheet metal bending can also produce various shaped shells, more processes and higher technical requirements may be needed when dealing with complex shapes, and the cost is relatively high.

[0109] (7) Because the processing process of aluminum profiles is relatively simple and easy to control, the processing precision is high, and the surface quality is also good; in addition, the surface of aluminum profiles can also be treated in various ways (such as powder spraying, anodic oxidation, etc.), to meet different decoration and performance requirements. During the steel plate sheet metal bending process, defects such as bending cracks, springback, indentation, etc. may occur, affecting the processing precision and surface quality; although these defects can be reduced by adjusting the process parameters and die design, the processing difficulty and cost may be higher compared with aluminum profiles.
