1. Installation and Debugging of CNC Steel Bar Straightening and Cutting Machine
Before starting the installation process, ensure that all components of the machine are complete and properly positioned. If the machine is to be placed near a wall or adjacent to other structures, sufficient space (approximately one meter) should be left for maintenance and servicing. Additionally, allocate ample area for storing raw materials and create a convenient location for stacking and transporting finished products. A solid concrete foundation should also be prepared, measuring approximately 11,000 x 1,500 x 200 mm in size.
Once the groundwork is complete, proceed with the installation of the main unit. Secure the four bases of the machine using M12 expansion bolts, ensuring that the machine is levelled. Next, attach the blanking rack, aligning the centerlines of the grooves in the traction wheel, the round knife in the trolley, and the blanking rack so they lie on the same straight line. Ensure the blanking rack is slightly lower than the main machine, about 20 mm.
After securing the main unit, lubrication becomes crucial. Pour 1 kg of gear oil into the traction box and add between 40-50 kg of anti-wear hydraulic oil into the hydraulic tank. For summer, use 45#, while for winter, opt for 32#. Regularly lubricate the front and rear bearings of the frame as well as the wheel bearings every two shifts with butter.
Connect the electrical control box to a stable operating area away from vibrations. After opening the control box, connect the straightening motor cable to the "straightening" terminal, the cutting motor cable to the "hydraulic terminal," and the solenoid reversing Valve cable to the "solenoid valve terminal." Finally, carefully connect the 380-volt power cord to the "power supply terminal." Be sure to use international copper cables no smaller than 6 mm² for distances up to 50 meters.

2. Working Principle and Adjustment Method of Hydraulic Station
The hydraulic station operates using a 4KW/5.5KW motor, which powers a Y13-D25 blade pump to supply oil. The hydraulic oil exits the blade pump and flows into the integrated block, then moves through the solenoid reversing valve. In a non-operational state, the oil circuit remains unpressurized, returning directly to the oil tank via the solenoid reversing valve. During operation, under the guidance of the electric control box, the hydraulic oil builds a fixed pressure (typically 6-8 MPa), as indicated by the shock-resistant pressure gauge on the integrated block. When the high-pressure oil pipe is engaged, the cylinder piston rod extends (cutting action) for approximately 0.17 seconds. The timer in the electric control box automatically reverses the electromagnetic reversing valve, allowing the hydraulic oil to return to the tool, retracting the cylinder piston rod (resetting the tool). Adjust the pressure using the safety pressure control valve but avoid excessive pressure, as this could overload the motor and potentially cause damage. This configuration has been preset at the factory, and adjustments should only be made by professionals if absolutely necessary.

3. No-Load Test Run
Switch on the power supply and activate the electronic control box's power switch. Confirm that the indicator light on the control panel illuminates and verify the voltmeter reading, ensuring it falls within 380 ± 20 volts. Once confirmed, press the "Hydraulic On" button to start the hydraulic motor. Check the motor's rotation direction; if it’s incorrect, reverse the wiring. After verifying proper operation, press the "Start" button to engage the traction and straightening motors. Press the "Stop" button to confirm functionality. Only after confirming normal operation should you proceed with further debugging.
For testing, pull out the wire plate for a segment and manually adjust about 2 meters. Release the handle wheel and install the pre-adjusted wire, following the sequence: wear-resistant sleeve of the feed port – push box traction wheel – traction box traction wheel – round cutter hole. Tighten all screws securely after adjusting the curve. Input the desired number of cuts and set the length before initiating the machine.
By adhering to these steps, you’ll ensure efficient operation and minimize risks during setup and usage.
