  • Bearing seal structure configuration selection

    introduction:The shaft is made of two bearings[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。]Supported in radial and axial directions,The bearing on one side is called the fixed-end bearing,It bears both radial and axial loads,It acts as the relative axial displacement between the fixed shaft and the bearing box。The other side is called the free end,Bear radial loads only,The axis can move relative to each other。

  • Design of drawing progressive die

    introduction:The drawing progressive die requires the material to be machined to have good plasticity,Must be able to adapt to multiple drawing without affecting the drawing form due to cold hardening。This is due to the belt material during the deep drawing process,Intermediate annealing is not possible,Its also not easy to use lubricants。When the progressive die is drawn,The dimensions of the workpiece should be in50mmbelow,Material thickness less than1.2mm,The thickest is not greater than2mm。 Considerations for designing deep drawing progressive dies: 1、 Because the holding force required for the first deep drawing is smaller than that of the subsequent processes,Therefore, the pressing ring of the first drawing process and the preceding cutting process must be separated from the pressing ring of the subsequent processes
