introduction：INAbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The installation must be dry、Carried out under clean environmental conditions。The mating surface of the shaft and housing should be carefully checked before installation、Convex shoulder end face、Machining quality of grooves and joint surfaces。All mating surfaces must be carefully cleaned and burrs removed，The raw surface of the casting must be cleaned of molding sand

introduction：today，Consumer products come in ever-changing styles，It has to look good、Exquisitely designed，It also needs to respond quickly to market demand。Designers generally use consumer products for different purposes，On different parts，Different materials are used，To meet the needs of specific environments，Achieve extended product life、Increased aesthetic and functional goals。This practical design requirement will undoubtedly complicate the production technology，The double material injection molding process is born in response to this trend。 General two-material products can be manufactured by single-color injection molding machines，Basically, an injection molding machine can do the job，However, the post-processing process is time-consuming and complicated，Directly affect the product

introduction：Industrial automation instrument used to measure gas or liquid pressure，Also known as pressure gauge or pressure gauge。A force that acts vertically and uniformly on a unit area is called pressure，Also known as pressure。Pressure gauge can indicate、Pressure values are recorded and an alarm or control device can be attached。The pressure measured by the instrument includes absolute pressure、Atmospheric pressure、Positive pressure（It is customary to call gauge pressure）、Negative pressure (Traditionally called vacuum)Sum differential pressure。figure1[The relationship between different kinds of stress]Denotes the relationship between various pressures。In engineering, the measurement is mostly gauge pressure。The international unit of pressure is paras(Pa)。Other units of stress are：Engineering atmosphere(kgf/cm()

introduction： one、introduction Automobile covering parts are sheet stamping parts that make up automobile body，Material thin、Complex shape、Large structure size、High surface quality requirements and high production costs。Stamping parts with more complex shapes can be completed through multiple processes，But the quality of the covering is largely controlled by the quality of the drawing die，Therefore, the design of drawing parts is the key to flush out high-quality stamping parts。How to quickly and accurately predict the wrinkling that may occur during the whole stamping process、Defects such as cracking and undesirable rebound are determined and some important stamping parameters are determined，It has become a bottleneck problem in the development of stamping technology。Along with the
