In the Steel Stamping Parts of this product, for all of its knowledge points, we should learn to understand and master, such as its design principles, so the following, since the above has been put forward, it is not too late Immediately to explain the contents of it, hoping to give you some useful, so that we can better understand the Steel Stamping Parts.
Steel Stamping Parts of the design principles, the main, mainly the following are:
(1) designed Steel Stamping Parts, must be able to meet their technical requirements, and the use of requirements, but also to be able to facilitate the assembly and repair and so on.
(2) can improve the utilization of materials, reduce material consumption, to minimize the generation of waste.
(3) the shape of Steel Stamping Parts should be as simple as possible, but also to the structure is reasonable, that is, should be the least and the most simple stamping process to complete the entire stamping and parts processing, and stamping operation to facilitate.
(4) its finished product size and surface roughness, etc., to meet the requirements, and to be able to guarantee its quality.
Steel Stamping Parts, but also related to automotive Steel Stamping Parts, these two aspects of knowledge to explain, today Xiaobian mainly to carry out its dimensional tolerance of this aspect, that is, to specifically explain this related knowledge, so that we can Better to learn and understand, so you can firmly grasp the following content, and to learn to use, so that this study more meaningful and valuable.
Steel Stamping Parts of the dimensional tolerance, the general is to comply with the provisions of GB / T13914-2002 requirements. For flat Steel Stamping Parts, the dimensional tolerance is divided into eleven levels, with ST1 to ST11 to represent. Also, the larger the number, the lower the precision level.
For forming Steel Stamping Parts, the dimensional tolerances are divided into ten grades, expressed in FT1 to FT10. The same, the greater the number, the lower the accuracy level.
Steel Stamping Parts of the limit deviation, the hole size deviation is zero, the upper deviation is the lower deviation with the size of the tolerance obtained. For the shaft size, it is specified that the upper deviation value is zero, the lower deviation is to use the upper deviation minus the size tolerance to get.
Steel Stamping Parts, the inspection of its work, which is also an important aspect of the product in terms of. So, based on this factor, and now Xiaobian some free time, then the following, to the specific good description of its content, so that we can learn clearly understand, to thoroughly understand and master, and then can be well applied to Actually gone.
Steel Stamping Parts of the test, the main method, in general, the words are mainly the following, its specific is:
Method one: touch test
First wipe the surface with gauze, and then check the staff to bring touch gloves, and along the Steel Stamping Parts of the vertical touch. It is a quick and effective way, but need to have some experience Caixing.
Method two: flexible gauze grinding
First wipe the surface with gauze, and then use a flexible sand net to close the surface of the Steel Stamping Parts, and polished the entire surface along the longitudinal direction to check whether the surface of the indentation or pitting.
Method three: oil test
First wipe the surface with gauze, and then the entire surface of the oil, pay attention to the direction of oil to be consistent. After that, put it under the test light, whether there is pitting, ripples and so on.
Steel Stamping Parts manufacturing process, which is mainly determined by the product shape. Even the simplest, but also a process; complex, there may be 7 to 8 processes, to be able to complete. But the general, open materials, pressure and notch these three processes, is essential.
In this case, I am afraid that there are difficulties, because different Steel Stamping Parts, its technology, methods, materials and complexity, etc., is not the same. However, its conventional, can be carried out to calculate. Below the simple Steel Stamping Parts, you can use manual calculations. More complex words, you may have to use the software.
