In the modern steel door manufacturing industry, the bending solution occupies a key position. The solution focuses on the molding of all types of steel door frames and has excellent applicability. Whether it is civil security doors, building fire doors, or medical, electronic industry used in the purification of the door, it can easily cope with the complexity of the product size, to fully meet the diversified production needs.

In the face of non-standard door frame bending needs, bending machine stand-alone program is to show unique advantages. The assembly line is usually designed for standard door frames, and when facing non-standard door frames, the process of adjusting molds and parameters is complicated and time-consuming. The bending machine process independence, can flexibly respond to non-standard size and special molding needs, quickly adjust the parameters and molds, easy to achieve personalized bending. Even if a single mold failure, it will not cause the entire production to come to a standstill, to ensure a smooth production rhythm. In addition, its initial equipment investment costs are relatively low, for the need to frequently respond to non-standard door frame orders, the pursuit of flexible production and cost-effective balance of the enterprise, door frame bending machine single molding program is undoubtedly the ideal choice.

In terms of the working principle, the cut door frame blanks are placed accurately on the bending machine table. By pre-setting the bending angle, sequence and other parameters in the control system, equipment start, high-precision bending molds in accordance with the instructions, bending the blanks one by one. Each bending process is monitored in real time by a precise sensing system to strictly control the bending accuracy. In order to meet the needs of different door frame lengths, the equipment is equipped with precise positioning devices, which can accurately set the length before bending. After the blank is bent in place, the cutter quickly cuts off the material, while the door frame splicing port completes the molding. For special process requirements, such as special treatment of corners, etc., auxiliary tooling can be added to realize. After the frame is formed, the corresponding holes can also be accurately stamped according to the installation requirements of the hardware fittings, which fully demonstrates the wide applicability of the program and helps the enterprise to complete the door frame bending and forming tasks efficiently and with high quality.
