What are the matters needing attention in the drawing processing of metal stamping parts

When a hardware stamping parts manufacturer processes stamping parts, it is necessary to use stamping equipment to process the drawing depth. Under the pressure of the punch, the stamping process of forming an open and hollow part through the die is called stretching. The commonly used methods are as follows. 1. panel drawing method Cladding is a kind of metal stamping parts with complex surface shape. In the drawing process, the deformation of the blank is more complicated. Its deformability is deep drawing and expansion. 2. Ellipse The deformation of the blank at the flange is a drawing deformation, and the deformation amount and deformation speed change correspondingly along the contour shape. When the curvature is large, the plastic deformation of the blank is also large. Conversely, when the curvature is small, the plastic deformation of the blank is also small. 3. step stretching method The left side of the original deep-drawn product is re-stretched to form the bottom of the right ladder. The deeper part is deformed in the early stage of wire drawing, and the shallower part is deformed in the late stage of wire drawing. The side wall of the step-changing part is easily affected by shear stress. And deformation. 4. cylindrical deep drawing Drawing of cylindrical metal dies with flanges. The flange and the bottom surface are planar, the side wall of the cylinder is axisymmetric, the deformation is evenly distributed on the same circumference, and the flange has a tensile deformation effect on the blank.

Maintenance knowledge of suspension system

The shock absorber is a key component in the suspension system that plays a buffering and damping role. Regularly check the shock absorber for oil leakage, excessive rebound, etc., to ensure the normal operation of the suspension system. It is generally recommended to replace the shock absorber every 20000-30000 kilometers.

How much do you know about the maintenance and maintenance cycle of auto parts?

The car is an indispensable means of transportation in modern society. For many people, the car has become an indispensable part of life, so the maintenance of the car is particularly important. The maintenance of auto parts is not only related to the performance and comfort of the vehicle, but also directly related to the safety of the driver and passengers. Proper maintenance can not only extend the service life of the car, but also avoid dangerous situations caused by component failures. Next, let us have an in-depth understanding of the maintenance methods and maintenance cycles of common auto parts.
