What should be paid attention to when installing and debugging the in-mold asynchronous die-cutting machine?

The question you asked is crucial! The installation and debugging of in-mold asynchronous die-cutting machine should focus on controlling equipment positioning, synchronization accuracy, die adaptation and safety protection, and the core is to ensure mechanical and electrical coordination and stability and avoid later operation failures.

First, the installation preparation points

Adaptation between site and foundation: the installation ground should be flat and firm, and the bearing capacity should meet the equipment parameters (usually ≥500kg per square meter). Equipment operation space (at least 1 meter around) and maintenance passage should be reserved to avoid being close to vibration sources or areas with high dust.

Equipment inspection and placement: after unpacking, check the integrity of the main engine, mold, electrical box and other components, and check whether the fuselage is damaged by transportation; Use a spirit level to calibrate the equipment level, and the error shall be controlled within 0.2mm/m, so as to avoid the operation deviation caused by inclination.

Pre-treatment of power supply and gas circuit: connect three-phase alternating current (voltage fluctuation ≤ 5%) that meets the equipment requirements, and equip with independent grounding device (grounding resistance ≤ 4 Ω); Compressed air needs to be filtered and dried (water content ≤ 0.01g/m, pressure is stable at 0.6-0.8MPa), and pipeline impurities shall be purged before gas path connection.

Second, the core debugging operation matters needing attention

1. Debugging of mechanical parts

Installation of mould base and mould: the mould installation needs accurate positioning, the gap between mould base and slide block is controlled at 0.01-0.03mm, and the fastening bolts are tightened in diagonal order to avoid mould deformation; Manually test the mold to check the movement track of the mold to ensure that there is no jamming and collision.

Calibration of asynchronous mechanism: adjust asynchronous cam and linkage mechanism to ensure asynchronous timing matching between die-cutting action and stamping/injection molding process (error ≤0.02s), and observe the consistency of die-cutting position through low-speed running test of handwheel.

Adjustment of guiding and pressing device: the guiding column needs to be coated with special lubricating oil to ensure smooth sliding; The pressure of the blank holder is even (0.3-0.5MPa), so as to avoid material damage caused by too tight blank holder or positioning deviation caused by too loose blank holder.

2. Electrical and control system debugging

Wiring and sensor inspection: check whether the wiring in the electrical box is firm, the sensor (photoelectric switch, proximity switch) is installed accurately, and the signal transmission is stable; Test the emergency stop button, safety door and other protective devices to ensure that the equipment stops immediately after triggering.

Parameter setting and synchronous calibration: input parameters such as die-cutting speed, stroke and asynchronous delay into the control system, and start trial operation at a low speed (≤10 times/minute) to gradually increase the speed; The synchronization accuracy is monitored in real time through the touch screen, and the servo motor parameters are adjusted in time when the deviation exceeds the limit.

Three, commissioning and safety protection points

No-load test run: run for 30-60 minutes without load, monitor the vibration and noise of the equipment (≤75dB) and the temperature of each component (bearing temperature ≤60℃), check whether the lubricating oil circuit is smooth, and promptly eliminate leakage, abnormal noise and other problems.

Load test and verification: small batch die-cutting test is carried out using actual production materials, and the dimensional accuracy (tolerance should meet product requirements) and edge burr (≤0.01mm) of die-cutting parts are checked, and it is confirmed that asynchronous action has no interference, and the material transportation is smooth and without deviation.

Safety specification implementation: protective gloves and safety helmet must be worn during debugging, and it is forbidden to touch the die-cutting area when the equipment is running; Non-professionals are not allowed to modify electrical parameters or remove safety devices without authorization to avoid safety accidents.

Fourth, the late closing and recording

After debugging, clean up the oil stains and impurities on the surface of the equipment, and carry out rust prevention treatment on the easily worn parts (die cutting edge and guide sleeve);

Record the installation and debugging parameters (such as voltage, air pressure, synchronous delay, die cutting speed, etc.), test results and fault handling in detail, and form a debugging report for later maintenance reference.
