Equipment Usage 

        Used for forming various steel and stainless steel door frames such as anti-theft doors, fire doors, medical doors, and purification doors, and cutting them according to length and cross-sectional requirements.

Principles of homework

After the roll material is fed, the door frame shape is formed by cold bending. After the forming is completed, the section shape and length output are achieved through hydraulic punching and shearing. At the same time, the entire line adopts a PLC control system, and the door frame length can be customized according to needs. The punching and shearing section can be selected according to needs. One device can achieve the production of the upper frame/lock frame/hinge frame of the entire door frame (the material and frame shape of the lower frame can also be synchronized).

Product features

●  Fully automated homework, one click on/off, can be operated by a general worker, and computer ordering software can be configured as needed to achieve office ordering, with convenient operation and high degree of automation;
●  All processes can be completed online without the need for additional turnover space or idle turnover, maximizing production efficiency and site utilization;
●  The cutting method can be freely combined, and one device can complete the forming of the upper frame, hinge frame, and lock frame of the door frame without the need for additional equipment;
●  Assembly line operation, mass production, has high production efficiency for mass production standard frames, and can also achieve frame shapes that cannot be achieved by some bending methods, with wide applicability;
●  Independent memorial archway structure+gear box structure, stable operation, uniform and powerful, convenient disassembly, more suitable for thick plate production;

technical parameter

Detail display

1. Material feeding rack: used for placing coils and achieving autonomous feeding

●  Equipped with a standard feeding rack, with a maximum weight capacity of 5T;
●  The feeding rack adopts a hand cranked locking and buckle fixation method, providing dual protection to ensure that the roll material will not slip off;

2. Host rack: The main structure of the device, which is the backbone of the device

●  The chassis of the main engine is welded with square tubes, and the welded structure undergoes professional stress analysis to ensure stability and solidity;
●  Independent memorial archway structure is adopted, and memorial archway is forged at one time, with high workpiece accuracy;
●  A 30mm thick steel plate is paved between the memorial archway and the underframe, and the surface is milled by CNC gantry milling to ensure the levelness of the memorial archway;
●  The main frame adopts a segmented structure for easy transportation, and there are dedicated connecting accessories between the segments, forming a unified entity;

3. Roll rolling device: By rolling and stretching, the door frame shape is formed

●  Front curved feed guide rotation, adjustable feed width to ensure stable and non running feed during rolling;
●  The rolling molds all adopt the processing technology of CNC lathe machining → heat treatment → CNC lathe precision turning, which ensures the roundness of the molds while making them durable and not easily worn;
●  The roller shaft is treated with 40Cr quenching and tempering, and processed by a CNC lathe. It precisely fits with the roller mold, ensuring the levelness of the roller and reducing fluctuations during the stretching process;
●  After the rolling is completed, it will be adjusted through a specialized correction device to ensure the perfect fit of the formed frame shape;

4. Transmission device: Through gearbox transmission, the rolling device is driven to perform rolling and stretching

●  The transmission adopts a gearbox structure, which runs smoothly and has low noise. It is composed of independent modules for easy maintenance and replacement in the future;
●  Adopting a vertical reducer (motor and reducer in one) to reduce placement space;

5. Cooling device: By spraying saponified water, heat dissipation during the rolling process is achieved while reducing friction
●  The cooling water outlet is evenly distributed next to the rolling device, and each outlet is equipped with an independent switch that can be turned on or off according to demand to control the size of the water flow;
●  The rack is equipped with a return water system, which can independently return water to the water tank, forming a water cycle, so that the cooling water can be recycled;

6. Cutting device: Through hydraulic cutting, the door frame cross-section is cut and formed

●  The cutting die is made of Cr12Mov material and processed by wire cutting, which fits the required frame shape and is durable;
●  The straight cutting knife (mainly used for flat cutting of door frame sections) or the step knife (directly cutting the insertion interface while completing the door frame section cutting) can be freely combined according to the section requirements, and one machine can complete the production of the same frame type but different sections;
●  The cutting method adopts hydraulic pressure, with greater force and no burrs on the cutting surface;
●  All types of hydraulic components are imported or international first tier brand products, which are durable and long-lasting;

7. Discharge rack: used for receiving finished door frames;

●  Equipped with a set of discharge racks as standard, capable of self feeding after cutting, facilitating the cutting of finished material frames;
●  The discharge is equipped with a height adjustment device, which can adjust the height as needed and has high flexibility;

8. Electric control system: equipment control system;

●  The whole machine is controlled by a PLC numerical control system, and can be equipped with Siemens, Delta, Mitsubishi, etc. as needed;
●  The production method can be independent frame mass production or alternate production of door frames in one trip. The production method is flexible and can be set according to needs;
●  The system operation is simple, with one click power on and one click power off, easy to teach, and low skill requirements for workers.

The cooperation that the user should provide

        1. Power supply: 380V, 50HZ, voltage fluctuation range from -5% to+10%; When there is a significant fluctuation in voltage, users must be equipped with a voltage regulator, otherwise it will cause low-voltage electrical appliances to be in an abnormal working state, reduce or damage the service life of electrical components, scrap processed products, motor alarm causing shutdown, computer hard disk damage, and other problems.
        2. Gas source: Output 0.6Mpa or above, dry and clean compressed air, with a supply rate of 0.3 cubic meters per minute; If the air dryness is not sufficient, users should be equipped with a refrigerated dryer, otherwise there may be problems such as water ingress into the pneumatic components causing increased piston friction resistance, wear of the sealing ring leading to air leakage, especially in winter, which is prone to icing and exacerbates damage to the pneumatic components.
        3. Environmental temperature: 0 ° C to+40 ° C; Below 0 ° C, it can cause components such as oil-water separators and air tanks that may contain water to freeze. Lubricating oil becomes too viscous due to low temperature, affecting lubrication effectiveness and leading to component damage or failure.
        4. Environmental humidity: Relative humidity of 20-80% RH (non condensing).
        5. Stay away from strong vibration sources and electromagnetic interference; If the distance is too close, the user must be equipped with a filter, otherwise it may cause problems such as computer screen flickering, LED flashing, driver alarm, encoder abnormality, or interference with other nearby devices.
        6. An environment with little dust and no harmful or corrosive gases.
        7. Do not cut off power while the equipment is in operation and maintain voltage stability.
