Brief introduction: installation and debugging process of knife die bottom die machine

The installation and debugging of the knife die bottom die machine is the key link to ensure the normal operation of the equipment and the machining accuracy. The process can be roughly divided into the following steps:

First, preparation before installation

Site and environment inspection

Confirm that the installation site is flat and firm, and can bear the weight of the equipment (to avoid accuracy deviation caused by ground settlement).

The environment needs to be dry and ventilated, away from dust, corrosive gases and strong vibration sources (such as punching machines and large fans).

Reserve equipment operation space (generally it is recommended to be at least 1.5m around) to facilitate maintenance and material loading and unloading.

Foundation and fixation

If the equipment has anchor bolts, the concrete foundation should be poured according to the requirements of the manual, or it should be fixed directly on the ground (small equipment can be omitted, but stability should be ensured).

Adjust the equipment level (error ≤0.1mm/m) with a spirit level, and realize it by adjusting the anchor screw to avoid abnormal operation sound or component wear caused by inclination.

The power supply is connected with the air supply.

Connect the power supply according to the rated voltage of the equipment (such as 380V three-phase electricity), and it is necessary to equip with an independent circuit breaker, with reliable grounding protection (grounding resistance ≤4Ω).

If the equipment needs pneumatic components (such as pressing device), connect compressed air pipeline (air pressure is generally 0.5-0.8MPa) and install filter to remove water and oil.

Second, the equipment assembly and parts inspection

Installation of main parts

Assemble the machine tool bed, workbench, spindle and other core components according to the instructions to ensure that the connecting bolts are fastened (to avoid loosening during operation).

Check whether the moving parts (such as guide rails and sliders) are smooth and stuck, and add lubricating oil if necessary.

Auxiliary system installation

Install cooling system (such as water tank and water pump) to ensure smooth circulation of coolant and aim the nozzle at the processing area.

Connect the dust suction device (if any) to prevent the accumulation of processing dust from affecting the health of equipment and operators.

Third, the debugging process

Power on test

Before the first power-on, check whether the circuit connection is correct, turn on the machine after confirming that there is no short circuit risk, and observe whether the indicator light and motor are started normally and whether there is abnormal noise.

Test the emergency stop button function to ensure that the power supply can be cut off immediately in an emergency.

parameter setting

Set the basic parameters through the equipment control system (such as PLC, touch screen): machining speed, tool speed, workbench travel limit, etc., refer to the recommended values in the manual.

Calibration coordinate system: take the datum plane of the workbench as zero point, and manually move the shaft to confirm whether the coordinate display is accurate (the error should be ≤0.01mm).

Trial cutting and debugging

Install standard trial cutting materials (such as wood board, acrylic, simulating the material of the bottom die of the knife die), and install tools (such as milling cutters) for trial cutting in a small range.

Check the machining accuracy: measure the size and flatness of the trial cut. If the deviation is out of range, adjust the verticality of the spindle, the compensation parameters of the cutter or the level of the workbench.

Test the automatic operation function: set up simple machining procedures (such as straight line and circular arc cutting), and observe whether the equipment runs according to the instructions, and whether there is jamming or deviation.

Load test

Carry out full-load machining test (such as continuous cutting for 1 hour), check the motor temperature and bearing temperature rise (≤40℃) to confirm the stability of the equipment.

Test the effect of cooling and lubricating system under load to avoid failure caused by overheating.

IV. Acceptance and Record

Confirmation of acceptance criteria

According to the equipment manual, confirm that the machining accuracy (such as dimensional error and surface roughness) and running noise (generally ≤85dB) are up to standard.

Check whether the safety protection devices (such as protective covers and handrails) are effective and conform to the safety specifications.

Document record

Record the parameters (such as water level, voltage and air pressure), trial cutting data and adjustment items in the process of installation and debugging, and file them for subsequent maintenance reference.

Train operators and explain the operation process, daily maintenance points and common fault handling methods of equipment.

matters need attention

During the debugging process, it needs to be operated by professional technicians, so as to prevent non-professionals from changing the parameters without authorization.

If any abnormality (such as sparks, peculiar smell and violent vibration) is found, stop the machine immediately for inspection, and then continue after troubleshooting.

After commissioning, recheck the equipment level, fasteners and lubrication regularly (such as weekly) to prolong the service life of the equipment.

Through the above process, it can be ensured that the knife die bottom die machine reaches the designed machining accuracy and runs stably. The specific details need to be adjusted according to the equipment model and manufacturer's manual.
