Chain Terminal Crimping Machine: Pre-Use Adjustments and Troubleshooting Tips

The chain terminal crimping machine is a valuable tool for creating secure and reliable connections. However, before diving into your project, taking a few moments for adjustments and familiarization can ensure smooth operation and optimal results. Here’s a guide to essential pre-use checks and troubleshooting tips for your chain terminal crimping machine.

Mold Height Adjustment for Wire Core Crimping:

Loosen the Punch Tightening Screw: This allows for free movement of the punch.

Adjust the Mold Height: Use a small round rod to rotate the adjustment screw located on the upper thread. There are typically six equally spaced holes. Clockwise rotation raises the punch, while counterclockwise lowers it. Each adjustment incrementally changes the height by 0.25 millimeters.

Set the Punch Position: Once the desired height for wire core crimping is achieved, tighten the punch tightening screw to secure the adjusted position.

Adjusting Clearance Between Upper Blades:

Fine-Tune PC Press Height: This step ensures optimal pressure for crimping the wire insulation.

Loosen the Upper Blade Tightening Screw: This allows for blade movement.

Rotate the Upper Blade: The upper blade typically has eight indicators numbered 1-8. A higher number signifies a lower blade position, with each indicator corresponding to a 0.1-millimeter difference.

Set the Blade Clearance: Rotate the upper blade to achieve the appropriate clearance for proper wire insulation crimping. Tighten the upper blade tightening screw once the desired position is set.

Feeding Adjustment:

Move the Block to the Highest Point: Use the up and down keys on the control panel.

Loosen the Feeding Rack Locking Screw: This allows for feeder adjustment.

Adjust the Feeding Position: Rotate the feeding adjustment screw. Clockwise rotation moves the terminal backward, while counterclockwise moves it forward. This ensures the terminal is centered within the blade, and the material strip is positioned correctly.

Tighten the Feeding Rack Locking Screw: Once the feeding position is adjusted, secure the feeder by tightening the locking screw.

Important Safety Reminders:

Always remove the wrench: Before turning on the power switch, ensure all tools used for adjustments are removed from the machine.
Start with the punch at the highest point: This prevents accidental damage during machine startup.
Maintain proper voltage: Avoid excessive pressure on multiple terminals by ensuring the voltage supply is within the recommended range. If necessary, consider installing a voltage stabilizer to protect the machine’s lifespan.
Two-hand operation: For safety reasons, keep both hands off the machine table when starting the power operation.
Manual mode for adjustments: When adjusting the mold, ensure the machine is in manual mode, indicated by a red light on the control panel.
Troubleshooting Common Issues:

Faulty Foot Switch: If the foot switch becomes unresponsive, stiff, or damaged, replace it for smooth operation.

Continuous Punching: A malfunctioning setting switch might cause the machine to continuously punch. Check the setting switch and adjust or replace it if necessary.

Blown Fuse: A blown fuse can prevent the machine from functioning. Replace the fuse with one of the correct rating as specified in the user manual.

Sluggish Operation: If the machine’s mechanical action feels sluggish, apply grease 1 to 3 times daily on the designated oil holes: one hole with three sliding surfaces on the block and three holes on the mold. Additionally, maintaining the ambient temperature between -2°C and 50°C can help ensure smooth operation.

Motor Malfunction: If the motor exhibits signs of malfunction, such as smoking, immediately turn off the machine and check if the voltage matches the machine’s specifications. Using an incorrect voltage can damage the motor.

Stuck Mold: If the mold gets stuck and won’t slide up and down, do not operate the machine manually. Use the wrench to turn the screw at the rear end of the main shaft to move the block. Observe the upper and lower blades for any damage or signs of scratching the terminal or wire. Damaged blades can cause the mold to get stuck. In most cases, replacing the blades and adjusting the mold will resolve the issue.

By following these pre-use adjustments and troubleshooting tips, you can ensure your chain terminal crimping machine functions optimally and delivers reliable connections for your projects. Remember, proper maintenance and addressing minor issues promptly can prevent them from escalating into bigger problems, saving you time and money in the long run.
