(1) Fully automatic wire crimping machine stamping guide rail must be added oil lubrication filling hole at the top of the terminal machine once an hour, each filling 2-3 drops should not be too much. (2) Operators must clean the machine every day to remove dust and debris on the surface of the machine and excess oil pollution. (3) Grease must be added to the main speed bearing of the automatic wire crimping machine every week. The specific operation methods are as follows: Opening the rear cover of the wire crimping machine Removing the clip spring of driven pulley, Removing pulley, Smearing grease (uniformly applied on the surface of high speed bearing) and restoring (note: in the process of removing pulley, attention to bearing balls perhaps be lost). After 3-6 months using the fully automatic wire crimping machine, it is necessary to check whether the parts (wearing parts) need to be replaced, such as belt, and whether the spring elasticity of each part needs to be replaced. Whether the locking screw of the machine is loose or not, check whether the clamp spring is deformed, etc. Usually in the work, we not only need to know how to use the automatic terminal machine, but also need proper maintenance. Without maintenance, not only will reduce the life of the machine terminals, but also the maintenance skills of the automatic terminal machine will affect the efficiency of the machine. Maintenance process of automatic terminal machine 1. (Stepping Principle) The motor keeps turning. There is an internal wrapped breaker with a clutch. Every step produces a standard “O” coming out, which is the most common. 2. In the last five years, there has been a mute wire crimping machine with a servo. Its operating principle is different from that above. It just gives the servo a message, which is then transmitted to the motor and acts as an action. As long as the wire is worn, the applicator installed, production can start after the parameters are set in the picture. Wire crimping machine can be classified as pneumatic wire crimping machine, wire crimping machine, fully automatic wire crimping machine, mute wire crimping machine, universal wire crimping machine, continuous terminal cutting PIN machine,wire stripper terminator machine, semi-automatic mute wire crimping machine, wire cutting stripping and crimping machine, wire crimping machine, [...]
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.
Chinese wire terminator manufacturer introduce how to choose a good fully automatic double-ends wire crimping machine
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.
