Talk about our mechanical engineers under the epidemic

When I came into contact with people in 96 and 97, I was generally interested in electricity. Many of my friends are also learning and don’t want to work on machinery alone. But this is also a disadvantage. It feels bad for people and feels not doing business properly. The roots of machinery are not well established. But 96 and 97 have strong learning ability, after all, they are young people.

N95 face mask machine design guide line

Fully automatic high-speed N95 mask production line, including automatic raw material delivery, automatic transportation, cutting nose bridge strips, welding forming, nose bridge filling, ear strap welding, folding, cutting and recycling, and other complete process automation to complete the entire production process from coil raw materials to mask finished products .

Why the bolts “If it doesn’t loose, it will break as soon as it looses.”

When the bolt is broken, the easiest conclusion that people can draw is that the strength is not enough, so most of them adopt the method of increasing the strength level of the bolt diameter. This method can increase the pre-tightening force of the bolts, and the frictional force has also been increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, its investment is too large, and the benefits are too small.

Motor selection parameters, principles and methods

When the motor is running under load, the total internal loss is converted into heat energy to increase the temperature of the motor. The poor heat resistance in the motor is the insulating material. If the load of the motor is too large and the loss is too large to make the temperature exceed the allowable limit of the insulating material, the life of the insulating material will be shortened sharply.

Mechanical vibration and noise design

Traditionally, noise control engineers often used test methods to identify noise problems and repeated test methods to solve the problems. However, now many industries such as automobiles, aerospace, heavy equipment, industrial equipment, air conditioning, heating, home appliances, etc., are more focused on introducing simulation models for simulation at the early design stage. Therefore, design evaluation…

Design of Hydraulic High Velocity Cutting Machine

According to the systematic design concept, a hydraulic high velocity cutting machine was designed to meet the production of fast and accurate cutting round bar stock or wire. Subsequently, the performance and efficiency of the cutting machine was analyzed. This design work would provide enlightenment and reference in the cutting machine design field.
