introduction： Stiffening rib Ideal design In order to overcome the problems that may be caused by the large wall thickness，Use is an effective way to reduce wall thickness and increase rigidity。 Generally speaking，The rigidity of the component can be enhanced in the following ways §Increase wall thickness； §Increase the elastic modulus（Such as increasing the content of reinforced fiber）； §Design considerations。 If the material used in the design does not meet the required rigidity，Materials with greater elastic modulus should be selected。The simple way is to increase the content of reinforcement fibers in the plastic。however，Zaat

introduction：In order to make the above impact imported bearings[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]The material factor of life is at its best，First, it is necessary to control the original structure of the steel before quenching，The technical measures that can be taken are：hyperthermia（1050℃）Austenitic cooling speed630℃Pseudo-eutectoid fine pearlite structure was obtained by isothermal normalizing，Or so cold420℃Isothermal treatment，The bainite structure is obtained。The waste heat of forging and rolling can also be quickly annealed，fineness

introduction：Machine tool accessories that use suction to grip workpieces。The most commonly used suction cups are magnetic suction cups，It is usually rectangular or disk shaped。It uses magnetic forces to hold ferromagnetic workpieces tight，For surface grinding machines，It is also sometimes used in milling machines and lathes。Suckers are divided into two categories according to the magnetic source: electromagnetic suckers and permanent magnet suckers。①Electromagnetic chuck：There are multiple coils in the body（figure1[Electromagnetic chuck]）,A direct current is passed through to generate a magnetic field，Suction work；Cut off the power，Field extinction，Loose work。②Permanent magnet chuck：The body is packed with powerful permanent magnets arranged neatly and separated by an insulating plate（figure2[Permanent magnet chuck]）,When the magnet is aligned with the magnet on the sucker panel,

introduction：(1)Strict vacuum seal：It is well known that，Vacuum heat treatment of metal parts is carried out in a closed vacuum furnace，therefore，Obtain and maintain the original gas leakage rate of the furnace，Ensure the working vacuum degree of vacuum furnace，It is very important to ensure the quality of vacuum heat treatment of parts。So a key problem of vacuum heat treatment furnace，It is necessary to have a reliable vacuum seal structure。In order to ensure the vacuum performance of the vacuum furnace，A basic principle must be followed in the structure design of vacuum heat treatment furnace，That is, the furnace body should use airtight welding，At the same time, as little or no holes should be opened on the furnace body，Use less or avoid the use of dynamic seal structure，
