Generally, there are many reasons for overheating of bearings in automatic wire crimping machines. Among them, there are several common reasons. The wire crimping machine manufacturer introduce several reasons as below:
1. Friction between bearing cover and shaft.
Because the axis of the axle and the axis of the mechanical equipment driven by the terminal machine are not on the same line, or because of the inaccurate processing, the inner circle of the bearing cap is eccentric, so that the bearing cap and the axle are friction with each other. Light bearings heat, serious smoke, large high-speed motors will soon rub red. At this time, the machine should be stopped immediately, otherwise the automatic terminal machine will be burnt down.
2. If the belt is too tight or the axle center of the fully automatic wire crimping machine is not in the same straight line as that of the driven machine, that is to say, the bearing load will increase and the bearing will heat up.
3. The unbalance of inner and outer rings of steel ball bearings is one of the causes of heating.
The unbalance of inner and outer rings of terminal machine may be caused by machining. Because the seat and cover of automatic terminal machine are processed separately, sometimes the bearing holes on the two end caps are not coaxial (that is, the center line is not on one line). In addition, poor assembly, uneven tightness of the screw on the end cover, dust and dirt on the stop, etc., may also make the inner and outer rings unbalanced. If the inner and outer rings of the bearing are unbalanced, the steel beads and the inner and outer rings will be scraped, and the friction will increase and heat up. If there is no other reason, wipe the nose clean and reinstall, screw tighten one by one in diagonal order. A small amount of errors in processing can be improved by gradual automatic adjustment.
4. Too much or too little lubricating oil is also the cause of heating.
Bearing is used for a long time, the internal lubricant gradually reduces, resulting in insufficient lubrication, increased friction loss, so that the bearing heating, long-term oil shortage operation will cause bearing damage. Too much oil or too thick oil can also cause bearing overheating. In addition, if the lubricating oil is mixed with hard impurities, the bearings are not cleaned, or the bearings are cleaned with dirty oil, so that there are sand particles and iron chips in the bearings, the mechanical friction of the bearings will be increased and the bearings will be heated, and the bearings will be easily damaged due to the role of impurities.

Fully automatic wire crimping machine has the functions of automatic cutting, stripping, twisting and crimping, which is a highly automated equipment. In the course of using, how to detect and eliminate faults? Fortune Sky Technology teaches you how to detect and eliminate faults: only fully check and clean up the machine and equipment before working every day, most of the faults can be prevented. It is very important to check and clean up before operation. If a fault occurs in one part, it will affect the normal operation of other parts and make the fault more serious. Therefore, it is necessary to repair it in time when abnormal is found. This can reduce the normal production or other unnecessary losses caused by the failure of machinery and equipment.
1. Fault: The cutting length of the electronic wire is inconsistent
Reason a: the wire feeding roller is pressed too tight or loose;
Solution: adjust the gap between the two wheels with the fine-tuning parts of the roller so that the wire is not flattened and too loose to slip.
Reason b: Straightener is too tight or loose;
Solution: The principle of adjusting straightener is that straightener can play a straightening role and be delivered smoothly.
Cause c: abrasion of the cutting edge;
Solution: Replace the new cutting blade.
2. Fault: The length of stripping opening is different.
Reason a: the wire feeding roller is too tight or loose;
Solution: adjust the gap between the two wheels with the fine-tuning parts of the roller so that the wire is not flattened and too loose to slip.
Reason b: Cutter cut too shallow or too deep;
Solution: Debugging the knife edge to the appropriate position with the depth adjusting part of the cutting knife, so as not to hurt the copper wire and to smoothly peel off the insulation.
Reason c: Cutting tool abrasion;
Countermeasure: Replace new blades.
3. Fault: The machine can not start or stop in operation.
Reasons and countermeasures:
A. Check for current input (220V) and 6KG air pressure;
B. Check if the total number of settings has arrived or not, and if it has arrived, reset it and start it after power failure;
C. Check if there is a wireless material or a running part jammed;
D. Check if the wire crimping machine has signal connection or power connection and lead to the wire crimping machine without crimping.
4. Faults: uneven exposure of copper wire on the crimped terminal;
Reasons and countermeasures:
A. Check if the catheter of gun-type swing arm is attached to the wire;
B. Check if the cutter edge of wire crimping machine is relatively straight with the catheter of... read more

The fully automatic double-ends wire crimping machine consists of three parts: the motion part, the control part and the execution part. wire crimping machine manufacturer said the wiring harness processing equipments on the market can be divided into three categories according to the accessories used at present.
1. Mechanical fully automatic double-ends wire crimping machine:
The main working principle is to drive the movement of the machine by belt and cam. The advantage is that the price is cheap, but the disadvantage is that the mechanical parts are easy to wear and age after using for a period of time, and the maintenance and debugging are troublesome. Short service life.
2. Stepping fully automatic double-ends wire crimping machine:
It mainly drives the movement of the machine through stepper motor.
The advantage is that the price is relatively low and the appearance is close to the servo motor. Compared with the mechanical design, it is more exquisite. The disadvantage is that the domestic ordinary step motor is easy to lose step and affects the precision of the product. The service life is short. The price difference between domestic stepper motor and imported famous brand servo motor is about 10 times. At present, more small companies use stepper motors as servo motors, declare that they are all servo products, or use some unknown servo plus some cam mechanical parts to deceive consumers.
3. Full-servo fully automatic double-ends wire crimping machine:
mainly through the PLC servo drive signal to control the movement of the servo motor, the advantages are high accuracy, long service life, high cost-effective, the disadvantage is that the price is more expensive, the use of motion modules together, greatly ensuring the accuracy and service life of the product.
The main functions of the reducer are as follows:
1. The reducer can reduce the moment of inertia. Generally, the square of speed ratio is reduced. It can control start-stop and speed change in time.
2. Increasing the torque through the reducer is equivalent to increasing the input power, which can reduce the power required by the input motor.
3. Reducer has the function of protecting motor in transmission. Reducer bears large torque in operation.fully enclosed gear reducer motor transmits only the value of overload divided by deceleration ratio when overload occurs. If it is directly borne by motor, it may cause motor damage.
4. When the motor is directly connected to the load at low speed, in order to meet the output torque current, the motor will increase a lot, which will inevitably have higher requirements for the heat dissipation and insulation of the motor. It is also undesirable from the point of view of energy saving. If the reducer is used, the impact of these problems can be reduced.
The role of the motor module:
1. Flexible movement without gap
2. Easy to obtain high walking accuracy
3. High positioning accuracy
4. High rigidity in all directions
5. High allowable load
6. Can maintain high accuracy for a long time
7. Excellent speed.
