Butterflies fluttering their wings: a big change for automotive components

Butterflies fluttering their wings: a big change for automotive components

In the documentary American Factory, Cao Dewang, who is nearly 70 years old, shows the outside world a different kind of old man, who handles things personally and decisively, and is undoubtedly the centre of the film. The documentary, which takes Fuyao Glass as its chronicle, slowly opens up the often overlooked part of the huge automotive industry chain - glass. It is a common perception that a car is a structure with a cockpit and wheels, which is of course superficial, but also intuitive; even though smart cars are all the rage nowadays, the functional attributes of a car are still the same as a cockpit + wheels.

A simple way to judge whether a motor is good or bad

A simple way to judge whether a motor is good or bad

1, shaking table shaking, 500V shaking table can be, shaking the three terminals on the line to the motor shell insulation resistance, should be in 0.5M ohms above it means no short circuit to ground. 2, multimeter test: test A/B/C resistance between the three phases, whether equal, should be about the same, the difference is too much can also turn, but not for long, remember the larger the motor, the smaller the resistance! But not all three phases are 0 ohms, unless you are particularly large, such as 50KW above the motor. Remember that if it is a speed-controlled motor of 6 terminals resistance value is not the same. 3, check the bearings, fan, general wrap the motor so that all change, because sometimes the bearings hold dead will also burn the motor. 4, the no-load current of the motor is generally 10% to 50% of the rated current, sometimes the motor idling current is also zero. 5, the motor rated current running, is full load operation, the output power is basically 100%. Running current is small, indicating that the motor output power becomes smaller, is light load operation.

Motor anomaly analysis

Motor anomaly analysis

Fault identification must be very familiar with the various properties, structures and various parameters of the diagnostic object. The motor consists of several independent and interrelated operating systems: the electrical system, the magnetic circuit system, the insulation system, the mechanical system and the ventilation and cooling system.

Is the machining of precision mechanical parts very demanding and some of its comparisons

Is the machining of precision mechanical parts very demanding and some of its comparisons

Precision mechanical parts machining, its name is long, and it contains a lot of relevant knowledge, so based on this, the next is to carry out its related learning work, mainly to learn and master its related knowledge, so that the knowledge mastered can be put to use and flexible use, so as to avoid wasting it.   1. Is there a difference between precision mechanical parts processing and ordinary mechanical processing? This problem, from a professional point of view, the answer is yes, that is, precision mechanical parts processing and ordinary mechanical processing is some differences and some differences, so it is to know the specific differences between them, so as to correctly distinguish, and can be based on the actual situation and processing requirements to the correct choice, so as to well avoid the problem of wrong choice.   2. precision mechanical parts processing, the processing process and processing technology which is more important? Precision mechanical parts processing, it is involved in the processing process and processing technology, and the two to compare, because they are the same in importance, is no light, so it is impossible to compare, and from another point of view, this comparison does not have any meaning and value, is not necessary to carry out this work, therefore, this question has no answer and can not answer.   3. Are there any common processes in the machining of precision mechanical parts? This question, in this area of professional opinion the answer is yes, that is, for precision mechanical parts processing, it is some common processing technology, such as fine turning, fine boring, fine milling, fine grinding and grinding and other such specific processes, and, these processes should have some knowledge and understanding, at least to know what they are, so that according to the processing requirements to choose the appropriate processing technology.   4. precision mechanical parts processing, its processing requirements are very high? Precision mechanical parts processing, its processing requirements are very high, so it is certain that the answer to this question is yes. And, for its different processing is a different processing requirements, not that its processing requirements are uniform, so, is to specific analysis, so as to know which processing forms can be taken to meet the processing requirements.

Plastic mould parts factory teaches you the way to prevent rusting of ejector pins

Plastic mould parts factory teaches you the way to prevent rusting of ejector pins

It is well known that ejector pins are very prone to rusting. When a plastic mould parts factory finds a rusty ejector pin, if it is not treated, its service life will be quickly depleted and it will become less durable. So what should a plastic mould parts factory do when a thimble rusts? What is the right thing to do? 1. Plastic mould parts factory in the production of plastic moulds when the thimble rust a large part of the reason is the injection of water, the machine stops running off the water is impossible, improper operation is easy to cause the thimble rust, the correct method should be to turn off the water off the machine, so it can effectively prevent rust. 2. If the thimble is used correctly, it will be difficult to rust. When the thimble is out of use, we should also take measures to protect the thimble and use anti-rust oil or machine oil for rust prevention. 3. If the ejector pin of a plastic mould parts factory is rusty, when there is only a small amount of rust, you can remove the rust by brass wire or grinding stone processing. However, if the rust is serious, replace the thimble with a new one in time to keep your mould in good working condition.
