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.

What causes bad contact of wire crimping machine? For machines, poor contact has always been one of the main causes of failure, from small mobile phones, large computers, larger end-to-end sub-machines or aviation equipment. Since this problem is so important, we must pay attention to it. Let Fortune Sky wire crimping machine manufacturer analyze the bad contact problem of wire crimping machine today.
For a computer, the most common malfunction is the memory chip. For a wire crimping machine, the most common malfunction is the metal conductor inside the terminal. This part is the core part of the terminal. It transmits the voltage, current or signal from external wires or cables to the contacts corresponding to its matching connectors.
Because of its importance, the wire crimping machine is required to have stable and reliable contact and good conductivity. So what factors will cause poor contact of wire crimping machine contact structure?
In fact, this is a common factor, such as excessive processing size, unreasonable surface treatment technology such as heat treatment and plating, poor storage environment, poor and improper use and operation, etc., may make contact parts and coordination parts of automatic wire crimping machine poor contact.
Common fatal faults at terminals?
1. Poor contact
The metal conductor inside the terminal is the core part of the terminal. It transmits the voltage, current or signal from the external wire or cable to the contacts corresponding to its matching connector. Therefore, the contact parts must have excellent structure, stable and reliable contact retention and good conductivity. Due to the unreasonable structure design, wrong material selection, unstable die, excessive processing size, rough surface, unreasonable surface treatment process such as heat treatment and electroplating, improper assembly, poor storage and use environment and improper operation, all of these will cause poor contact at the contact and coordination parts of the contact parts.
2. Poor insulation
The function of insulator is to keep the contacts in the correct position, and to protect the contacts from the contacts and the shells from each other by insulating the conveyor. Therefore, insulators must have excellent electrical performance, conveyor protection mechanical performance and process forming performance. Especially with the wide use of high density and miniaturized terminals, the effective wall thickness of insulators becomes thinner and thinner. This puts forward more stringent requirements for insulation materials, precision of injection moulds and moulding technology. Due to the existence of metal redundancy, surface dust, flux and other contaminations on the surface or inside of insulators, the amalgamation of organic material precipitates and harmful gas adsorption film with surface water film to form ionic conductive channels, moisture absorption, long mold, aging of insulating materials and other reasons, will cause short circuit, leakage, breakdown, low insulation resistance and other bad insulation phenomena.
3. Poor fixation
Insulators not only play an insulating role, but also provide precise centering and protection for extended contacts. They also have the functions of installation, positioning and locking and fixing on equipment. Poor fixing, light impact on contact reliability, resulting in instantaneous power failure, the serious is product disintegration. Disintegration refers to the abnormal separation between plugs and sockets and between pins and sockets caused by unreliable structure due to material, design, process and other reasons, which will result in serious consequences of power transmission and signal control interruption of computer stripper in control system. Due to unreliable design, wrong material selection, improper selection of forming process, poor quality of heat treatment, die, assembly, welding and other processes, inadequate assembly will cause poor fixation.
In addition, due to coating peeling, corrosion, bruising, plastic shell flying edge, rupture, rough contact parts processing, deformation and other reasons caused by poor appearance, due to positioning and locking with poor size, poor consistency of processing quality, total separation force and other reasons caused by poor interchange, is also a common disease, frequently occurring. These kinds of faults can be found and eliminated in time in the process of inspection and use.

Fully automatic sleeve insertion terminal crimping machine is generally used to play the spring terminal and can automatically wear the jacket. To distinguish the quality of an automatic sleeve insertion terminal crimping machine, we can judge from the following aspects.
1. Whatever the buzzword, the principle is much the same.
First of all, depending on the configuration, a fully automatic terminal crimping machine with bad configuration is no better than that. Many times it is broken because of a screw or burr. Therefore, it must not be saved in this respect. The fully automatic sleeve insertion terminal crimping machine must be equipped with high configuration. The motor is the most basic servo, preferably the top Mitsubishi servo.
2. Stripping and cutting effect, we should carefully observe whether the wire stripped by fully automatic sleeve insertion terminal crimping machine will not be clean, stripping is not aligned, whether the copper wire is injured or not, whether the insulation is scratched or not, whether the wire is obvious crooked and different lengths or not, and so on. If the bad stripping will affect the effect of subsequent sleeve insertion and terminal crimping, which is not acceptable. Of course, there is an error in the length of stripping and cutting, which is 0.2 mm + (set length * 0.002 mm).
3. The effect of crimping terminal, the quality of a fully automatic sleeve insertion terminal crimping machine depends mainly on the effect of crimping terminal. If the crimped plug spring terminal is crooked, or does not crimp copper wire, or the crimping interface is loose, it will directly affect the quality of your product. This will be a fatal injury. As mentioned above, using Mitsubishi servo can better avoid this problem.
4. The speed of fully automatic sleeve insertion terminal crimping machine. If the above two points are almost the same, the working speed of fully automatic sleeve insertion terminal crimping machine will be another important indicator. Enterprises choose fully automatic sleeve insertion wire crimping machine mainly focus on its automation, if its speed is higher, it represents that it will bring you greater benefits, of course, the premise is that the wire harness processed by fully automatic sleeve insertion terminal crimping machine is qualified products.
5. Not long after the machine was born, the machine that just came out for a year or two may have many problems, instability, and we can’t pay for their instability.
Nowadays, there are many enterprises that produce fully automatic sleeve insertion terminal crimping machine and their appearance is quite similar. And now many enterprises will use automatic terminal crimping machine, so it is particularly important to know how to select terminal crimping machine.

Even the fully automatic operated fully automatic wire crimping machine can also cause malfunctions and adverse effects, so we often find some bad phenomena in actual operation.
There are main reasons as follow:
One is the unsatisfactory contact of wire terminals. In the final analysis, this is due to the unreasonable design of the corresponding infrastructure or the inconsistent selection of materials, which makes the normal transmission of voltage, current, signal and so on impossible. The other is the problem of poor fixing. The insulator on the terminal is not only to play an insulating role, but also to provide corresponding protection, positioning, fixing and other functions. The reason for poor fixation is actually from design, material selection, process and other factors.
In addition, poor insulation is also one of the common problems of terminals. Because there are some impurities such as metal redundancy, dust and flux on the surface and inside of the insulator of fully automatic wire crimping machine, ionic conductivity will be formed in the case of dampness and mildew, which leads to poor insulation phenomena such as short circuit, low insulation resistance, leakage and breakdown.
What functions does the wire crimping machine can provide?
The fully automatic ribbon cable wire crimping machine is used to connect terminals. It is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. Both ends have holes to penetrate the wires. There are screws to fasten or loosen the wires, for example, two wires, sometimes need to be connected, sometimes need to be disconnected. At this time, they can be connected by terminals. And can disconnect at any time, without welding them together or surround them, very convenient and fast. And suitable for a lot of wire interconnection, in the power profession there are special terminal row, terminal box, which is full of terminal, single-layer, double-layer, current, voltage, general, breakable and so on.
Our wire crimping machine has a certain crimping area in order to ensure reliable touch, as well as to ensure that the current can be satisfied. The fully automatic ribbon cable wire crimping machine uses the existing track connection terminal connection skills, and installs a circuit composed of electronic components to complete the transmission coupling of photoelectric process.

1. The main working principle of mechanical type is driving machine working by belt and cam. The advantage is cheap, but the disadvantage is that the mechanical parts are easy to wear and aging after using for a period of time, and the maintenance and debugging are troublesome. Short service life.
2. Stepping full automatic wire crimping machine is mainly driven by stepping motor. Its advantage is that the price is relatively low and the appearance is close to the servo motor. Compared with mechanical design, it is more exquisite. The disadvantage is that domestic ordinary stepping motor is easy to lose step and affects the accuracy of products. 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 mainly controls the movement of servo motor by servo drive signal provided by PLC. Its advantages are high precision, long service life, high cost performance, and its disadvantage is that the price is relatively expensive. The servo motor, together with imported famous brand reducers such as Shimpo in Japan, Sumitomo, HD, Alpha in Germany, is used together with the motion module (well-known ones such as THK, etc.), which greatly ensures the safety of the servo motor. The accuracy and service life of the product are proved.
The installation steps of automatic wire crimping machine are as follows:
1. Before installing the applicator, need to check whether the upper and lower die blades and feeding fastening screw are tightened or not.
2. Pull up the slider of the applicator and cover the sliding groove into the 2000 mould handle or (insert the power supply, press the adjustment button, rotate the back spindle counterclockwise with an open-mouth wrench, make the press slide down quickly and cover the sliding groove of the applicator into the 2000 mould handle).
3. Fix the bottom plate of the die and the working table of the press with the fixed screw of the press plate, so that the whole set of die can not be loosened (the whole set of die is in a solid state in normal operation).

(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... read more
