The Key to Efficient Production: Operation Guide for Two - Dimensional CNC Automatic Wire Bending Machine

I. Equipment Startup and Preparation

1. Equipment Inspection: Before startup, a comprehensive inspection of the equipment is required. Check whether the appearance of the equipment is damaged and whether all connection parts are firm. Inspect the lubrication system to ensure that there is sufficient lubricating oil and that all lubrication points have been effectively lubricated to reduce wear during equipment operation. At the same time, check the cooling system to ensure that the coolant level is within the normal range and that there are no leaks in the cooling pipes, ensuring that the equipment can be well - cooled during operation and preventing overheating from affecting equipment performance and lifespan.
2. Power Connection: Confirm that the power supply of the equipment meets the requirements, connect the power cord well, and ensure reliable grounding to guarantee the personal safety of operators and the stable operation of the equipment. After connecting the power, observe whether the indicator lights on the equipment control panel are normally lit. If there are any abnormalities, immediately troubleshoot the power supply failure.
3. Material Preparation: Select appropriate metal wires according to production requirements. Carefully check whether the material and diameter of the wires meet the requirements, and ensure that there are no obvious scratches, cracks, or other defects on the wire surface. Install the selected metal wires on the wire rack and ensure that the wires can be smoothly released to avoid jamming during the feeding process.

II. Parameter Setting

1. Basic Parameters: Enter the operation interface of the equipment's CNC system and first set the basic parameters. According to the material of the metal wire, such as iron, copper, aluminum, etc., select the corresponding material option, and the system will initially adjust the relevant parameters according to the preset material characteristics. Then input the diameter of the wire. Accurate diameter data is crucial for the selection and adjustment of the feeding wheel spacing and the bending die, as it directly affects the stability of wire feeding and the bending accuracy.
2. Bending Parameters: Set key bending parameters such as bending angle, bending radius, and bending speed according to product design requirements. For complex shapes that require multiple bends, set the parameters for each bending step in sequence according to the bending order. For example, for a workpiece that needs to be bent at 90 degrees first and then at 45 degrees, input the corresponding angle values in sequence in the operation interface and set a reasonable bending speed. For metal wires with higher hardness, the bending speed can be appropriately increased to improve production efficiency, but be careful to avoid uneven wire deformation caused by excessive speed. For softer wires, the speed should be appropriately reduced to ensure bending accuracy. At the same time, according to the elastic properties of the wire, reasonably set the spring - back amount to compensate for the spring - back after bending and ensure that the angle of the final product meets the design standard.
3. Feeding Parameters: Set the feeding length, which determines the extended length of the wire each time it is fed and is directly related to the dimensional accuracy of the product. According to the dimensional requirements of the product, accurately input the feeding length value. In addition, the pressure of the feeding wheel needs to be adjusted according to the material and diameter of the wire. For softer wires, reduce the pressure of the feeding wheel to prevent the wire surface from being damaged by pressure. For wires with higher hardness, appropriately increase the pressure to ensure that the wire can be stably and accurately conveyed.

III. Die Installation and Debugging

1. Die Selection: Select appropriate dies according to the diameter of the metal wire and the bending requirements of the product. For wires of different diameters, corresponding - sized feeding wheels and bending dies need to be matched. For example, when processing thinner wires, select smaller - sized dies to ensure precise control of the wire. When processing thicker wires, use larger - sized and higher - strength dies. At the same time, pay attention to the compatibility between the die material and the metal wire being processed. For example, when processing high - hardness metal wires, select cemented carbide dies to improve the wear resistance and service life of the die.
2. Die Installation: Before installing the die, ensure that the equipment is in a stopped state and the power is cut off to ensure operation safety. Install the selected die on the equipment in the correct installation method and use special tools to firmly fix the die to prevent the die from loosening during equipment operation, which may affect processing accuracy or even cause equipment failure. After installation, perform manual debugging to check whether the die opens and closes smoothly and whether all moving parts are flexible.
3. Die Debugging: Connect the power and start the equipment to enter the die debugging stage. Through the operation interface of the CNC system, control the equipment to perform simple feeding and bending actions, and observe the clamping, feeding, and bending effects of the die on the wire. Check whether the position of the wire in the die is correct and whether the bending angle meets the preset value. If there are any deviations, adjust the position of the die or re - set the relevant parameters for calibration until the die can accurately and stably process the metal wire.
   

IV. Equipment Operation and Monitoring

1. Equipment Startup: After completing the above preparations and confirming that the parameter settings are correct, press the startup button of the equipment, and the equipment will start to operate automatically. At this time, the equipment will automatically perform a series of operations such as feeding and bending according to the preset parameters. Operators should closely monitor the operation status of the equipment to ensure that the equipment operates smoothly without abnormal noise or vibration.
2. Production Process Monitoring: During the operation of the equipment, operators need to monitor the operation of the equipment at all times. Observe whether the feeding of the metal wire is smooth and whether there are any jamming or blocking phenomena. Pay attention to the quality of the bent products, check whether the bending angle and bending radius meet the requirements, and whether there are any scratches, deformations, or other defects on the product surface. At the same time, pay attention to the operation parameters of the equipment, such as feeding speed and bending force, to ensure that these parameters fluctuate within the normal range. If any abnormal situations are found, immediately press the emergency stop button, troubleshoot the cause of the failure, and take corresponding measures.
3. Quality Sampling Inspection: Conduct quality sampling inspections at regular intervals for a certain number of products. Use professional measuring tools, such as calipers and angle gauges, to measure the key dimensions and bending angles of the products to ensure that the product quality meets the production standards. For unqualified products detected during sampling, analyze the reasons, which may be changes in equipment parameters, die wear, or problems with the quality of the metal wire. Take corresponding solutions according to the specific reasons, such as re - adjusting parameters, replacing dies, or checking the quality of the wire.
   

V. Equipment Maintenance and Upkeep

1. Daily Maintenance: After the equipment is used, promptly clean the metal debris and sundries on the equipment surface and in the working area to keep the equipment clean. Supplement lubrication at the lubrication points of the equipment to ensure the good lubrication of all moving parts. Check whether the connection parts of the equipment's cables, air pipes, water pipes, etc. are loose or damaged. If there are any problems, repair or replace them in a timely manner. At the same time, regularly clean the CNC system of the equipment to prevent dust and other impurities from entering and affecting the normal operation of the system.
2. Regular Maintenance: Conduct a comprehensive maintenance of the equipment at regular intervals (such as weekly or monthly). Check the wear conditions of key components such as feeding wheels and bending dies, and replace severely worn components in a timely manner. Check and adjust the transmission system of the equipment, such as belts and chains, to ensure transmission accuracy and stability. At the same time, test the electrical system of the equipment, including checking whether the connections of all electrical components are firm and whether the electrical parameters are normal, to ensure the stable and reliable electrical performance of the equipment.
3. Fault Repair: If the equipment malfunctions during operation, immediately stop the equipment and troubleshoot according to the fault prompt information or fault phenomenon of the equipment. For some simple faults, such as sensor failures and loose wires, operators can repair them by themselves after powering off. However, for more complex faults, such as CNC system failures and serious damage to mechanical components, contact professional maintenance personnel for repair. Do not blindly disassemble the equipment to avoid causing more serious damage.
