Q:How to write the machining process design of machine parts?
According to each process that the part needs to be processed, the processing technique is determined. The so-called processing technology, that is: the processing of each process, the processing required to what extent?. If the text is not clear, you can draw the technical drawings to illustrate.
Q:Why do the design of mechanical parts (flanges and elbows) be based on the yield limit?
Hello friends, usually to do the experiment to the material ontology; have tensile, bending, impact, flattening, flaring, cyclamic, normal temperature test 20 degrees Celsius, is 20 degrees Celsius, minus 20 degrees Celsius, the test to the material, to be determined after completion of the test material meets the design requirements. Is the so-called (to yield limit for design basis?)
Q:Who knows what the design criteria for machine parts are, and how they are designed?
5. life standards, in order to ensure that the machine in a certain life span of normal work, in the design of mechanical parts, it is necessary to request the life of mechanical parts. It should be explained that parts can be replaced during the life of the machine, that is, the life of some mechanical parts is shorter than the life of the machine. The life of mechanical parts is mainly affected by fatigue, wear and corrosion of materials. In order to avoid failure caused by parts fatigue, such as fatigue fracture, fatigue strength should be calculated according to the fatigue limit corresponding to the life of mechanical parts. That is to say, according to the requirements of life and the specific speed of parts, according to formula (3-6), the fatigue limit is calculated when the stress cycle number is N. Then the strength condition is calculated and the fatigue strength is calculated. When the fatigue strength is satisfied, the stress cycle times of the mechanical parts can be guaranteed before the damage. Wear is usually unavoidable. Under certain conditions, corrosion is inevitable, such as structural members of bridges, corrosion of buried steel pipelines, etc.. In the design, mainly to ensure the mechanical parts in life, not excessive wear and corrosion. The mechanism of wear is still fully mastered, and there are many factors affecting wear. Generally, the wear resistance of friction pairs is improved according to the tribological design principle. The main measures are as follows: reasonable selection of friction pairs, reasonable choice of lubricant and additives, and control of the working conditions of friction pairs, such as pressure, sliding speed and temperature rise. So far, there is no practical and effective method for calculating corrosion life
Q:Who can provide mechanical parts design report,
Estimate is very suspended, needless to say, free of charge, that is, you go to buy, nor necessarily sell you. This is someone else's technical secret, it's not good to go inside for several years.
Q:Mechanical design of various parts of the hardness value of how to determine?.
You send out the request and I'll help you get it! Upstairs answer obvious mistakes, such as 45 steel, the best performance in 39-44HRC, but domestic heat treatment and foreign heat treatment level there are differences, the same hardness, foreign countries are several times more durable than the domestic!
Q:What are the key factors in designing mechanical parts?
1- reliability. For example, the design of a transmission shaft, to consider whether the uniform load or impact load, axial load or radial load or both, or combined force. In general, even small loads can be fitted with clearance or transition fit, and tolerances can be enlarged so that processing costs are low. For high speed or large load or impact loads, interference fit should be used, such as flywheel shaft of diesel engine.
Q:Mechanical manufacturing technology.
I was engaged in mechanical design and process about 10 years, are of their own design what is responsible for processing, the above parts is very simple, need to look at the parts of the mass in the factory to determine the blank shape, need to consider many, encouraging learning tyrants to stop showing off to the society, how to look and learn!
Q:Mechanical design, hardness of the workpiece, how to determine, for example, in the drawings, technical requirements of the hardness value how to get?
Different material requirements are not the same, conditioning, surface quenching, carburizing, nitriding and so on, the requirements vary, to see the use of parts and precision requirements. May refer to "mechanical design manual".
Q:Why some design parts can not be machined?
There should be a lot of things. For example, the processing capacity of the equipment is only 1000mm, and the things you design have 1100mm, so the existing equipment can not be processed. For example, the surface roughness you require is Ra0.2, and the machining accuracy of your equipment can only be Ra0.8. That's more than the processing capacity of the equipment. And some things are processing problems, for example, you design things outside the small hole, there is a big hole inside, your device does not have this function.Think of these kinds of things for the time being.
Q:At the time of mechanical design.
The drawing code is the design code. For example, abc-00.00.01, abc-00.00.02, etc., the company should have the principle of numbering and compiling according to the drawing code in the assembly drawing.
