10 Common Failures and Solutions of Fully Automatic Terminal Crimping Machine

Terminal crimping machine is an important equipment for wire harness processing in power industry and electrical industry,among others, which has many functions, such as wire feeding, wire cutting cutting, wire stripping, terminal crimping and so on.

In the process of use, once a failure occurs, it will affect the production progress, so it is necessary to understand some common faults of the terminal crimping machine and their solutions.

So what kind of common problems are often encountered in the use of the terminal machine?

How to solve these common problems?

Through this article, the editor and you have a simple understanding of the common problems of the terminal machine and their solutions.

Q1: What is the reason for the different wire cutting length?

A1: Possible reasons,

①The pressure of the wire feeding rollers is not enough, so the pressure needs to be adjusted;

②The wire feeding speed is too fast and needs to be adjusted to an appropriate speed;

③The gap of the feeding rollers is not suitable and needs to be adjusted.

Q2: What is the reasons of injuring the wire cores in the process of wire cutting and stripping?

A2: Possible reasons,

①The stripping blades is cutting too deep, adjust the stripping blades value;

②Adjust the blades retreating value;

③The stripping equipment is abnormal and needs to be adjusted.

Q3: In the process of wire stripping, why the front end can not be stripped off?

A3: Possible reasons,

①Check the stripping depth and adjust the blade value;

②The pressure of the wire feeding rollers is not enough, adjust the pressure;

③The blades retreating value cannot be set too big;

④The blade is notched and needs to be replaced.

Q4: In the process of wire stripping, why the back end can not be stripped off?

A4: Possible reasons,

①Check the stripping depth and adjust the blade value;

②The wire clamping claw can not tighten the wire, and the gap between the wire clamping claws shall be adjusted.

③The blades retreating value cannot be set too big;

④The blade is notched and needs to be replaced.

Q5: In the process of wire stripping, why one end hurts the wire cores and the other does not hurt the wire cores?

A5: Possible reasons,

①The depth of the blades edge at both ends is different, adjust the cutter holder

②The stripping blades did not reach the right position.

③The blade is worn, replace the blade.

Q6: In the process of wire stripping, why the wire scraps can not be come off?

A6: Possible reasons,

①The length of the half-strip setting is not suitable. Adjust the half-strip length;

②The insulation skin is not completely cut off, and the blade value needs to be adjusted.

③If the gap of the stripping clip is too large or the orientation is wrong, adjust the stripping clip.

Q7: What is the problem that the wire clamping claw can not hold the wire?

A7: Possible reasons,

①If the air pressure is too small or the gap is too large, adjust the air pressure and gap;

②The clamp claw is damaged, replace the clamp claw;

③If the claw orientation is wrong or the clamping time is not right, adjust the azimuth and clamping time.

Q8: What is the cause of motor overload or out of step?

A8: Possible reasons,

①Check to see if there are bumps or azimuth overruns;

②Check whether the speed is too fast or not, adjust the speed;

③Check if the drive cable is loose;

④Check whether the motor origin sensor is normal or not.

Q9: What is the reason for the poor quality of the crimped terminal?

A9: Possible reasons,

①Confirm if there is something wrong with the applicator, adjust it;

②Confirm if the mechanical action is accurate and adjust the action timing;

③Make sure the crimping is in the right position.

Q10: What is the cause of the abnormal operation of the machine?

A10: Possible reasons,

①Confirm whether there is a operational error or not;

②Confirm whether the motor is out of step and whether the driver has given an alarm;

③Confirm that whether the air supply and power supply are normal;

④Restart the closed mechanical power supply and confirm whether it is normal or not.
