Q:Good mechanical design or good mechanical manufacturing?
mold design is designed, is relatively easy. These industries are good, see what you want to develop it.
Q:What kind of software is used in the design of machine parts?
No, most, only the more, the most suitable for you is your most.If you usually design only 100 of the following parts, use SOLIDWORKIf it is under 1000, using proe is goodMore than 10000, then you use CATIAAs for UG, a little embarrassed, suspended in midair.
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:Where are the machine parts designed to be finished?
To the mechanical processing plant ah, there are many machinery processing plants are based on the processing of parts to others to survive, and our products are parts of those machinery factory processing
Q:Mechanical design, manufacture and automation, 60
The interests of postgraduate exams in the machinery industry are not very greatTo PubMed, it is best to change the professionI graduated from mechanical design,I graduated from graduate school for 1 years. I graduated four years agoTheir wages are not as high as mineThe reason is simple1, the machinery industry, experience is more important, more than three years of experience is often more important than academic qualifications2, starting point and pressure pointThe current stall in the machinery industry is undergraduate 3K, salary 3 years of 6K, 10 years is less than 10KGraduate 4K, work within 10 years is less than 10KThe starting point is a little different, one is higher than a high 1K, but you have to consider people of the same ageWhen you graduate with three years of work experience, the study pays less than your peers, but after years of work, the salary is basically the same
Q:In the design of large machinery, it is to design the parts first, the assembly drawings as well
This is the principle of the overall design process must go through to all aspects of the details, then how do you draw can use computer aided design. Now more flexible. If according to the traditional design from the general to the sub structure, clear whatever you draw.
Q:Mechanical design of various parts of the hardness value of how to determine?.
Give your reference value, heat treatment is most hard, probably 65HRC, this is the limitAnd 45 steel without heat treatment, only about 10When you design, the hardness does not require a material can be set, there are hardness requirements, then the technical requirements of hardness
Q:Can the bearings used in the design of mechanical equipment be used as part drawings?
(4459.7 GB/T 1998) for the following provisions: (1) the basic regulations and general characteristics of drawing, drawing, drawing in the various provisions of symbols, rectangular wire frames and contour lines are drawn with thick lines. When drawing a rolling bearing, the size of the rectangular frame and the outline of the outer frame should be consistent with the shape dimension of the rolling bearing (found in the manual) and the same proportion as the drawing. In the cutaway view, when drawing the rolling bearings by the universal drawing and the characteristic drawing, the section symbols (section lines) are not drawn. When drawing with the prescribed drawing method, the rolling body of the bearing does not draw a section line, and each ring can be painted in the same line section with the same direction and spacing, as shown in Figure a. Such as bearings with other parts or accessories (such as eccentric sleeve, tight sets, retaining rings, etc.), the profile line should be in line with the ring profile in different directions or different intervals, as shown in Figure B. Omission is not allowed in drawing without misunderstanding.
Q:What is standardization, serialization, and generalization?
Standardization refers to the products (especially parts) the quality, specifications, performance, technical index structure and other aspects of the unified regulations and standards to perform. As the standard of our country has already formed a huge system, there are national standards, industry standards and so on. In order to in line with international standards, some standards in China the rapidly move closer to international standards. The standard code such as GB, JB, ISO and so on, they are representative of the national standard of People's Republic of China machinery industry standards, the international organization for standardization standards.
Q:What are the basic criteria for the design of mechanical parts?
(2) the demolition of the old machine parts of the work, the stress components and their connections, should meet a predetermined maximum load enough strength, stiffness and stability during normal operation should not occur due to the work cycle or stress or fatigue fracture times have broken, excessive deformation or collapse; also must considering the stability of the whole mechanical equipment under the premise of the anti overturning wind or anti slide, especially those with mechanical vibration displacement load or its expected quality uneven distribution.(3) adequate adaptability to the use of the environment. The work equipment of the demolition of the old machine parts must be used to the environment (such as temperature, humidity, air pressure, wind load, snow load, vibration, and electrostatic, magnetic and electric fields, radiation, dust, microorganism, animal and corrosive medium) has enough ability to adapt, especially anti corrosion or erosion, aging wear, anti-interference ability, not because the electrical components affect the physical, chemical and biological caused by accident.
