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.

Counting the main factors affecting the tensile properties of metals

Although the tensile properties of metal materials depend on the properties of the material itself, such as chemical composition, structure, etc., even the same material may have different results in different tensile tests. There are many factors that affect the tensile properties of metals, which can be divided into two aspects: the nature of metal raw materials and the influence of processing on the tensile properties of metal materials.

What are the section characteristics of metal stamping parts

Good metal stamping parts section should first control the burr, the burr to minimize, followed by the pursuit of bright band, many require more precise metal stamping parts, customers will put forward the proportion of bright band in the whole section, of course, this is the scope of precision stamping.

Material Selection and Function of Hardware Shrapnel Stamping Parts

The material of the shrapnel is generally determined according to the use and performance of the shrapnel. For example, the use frequency of physical resilience is relatively high and the pressure degree is relatively high. Generally, spring steel, carbon steel or high hardness stainless steel is selected. After forming, heat treatment and quenching are carried out to reduce the carbon content and increase the pressing service life of the shrapnel by increasing the hardness. If it is necessary to achieve physical properties such as easy welding, acid and alkali resistance and conductivity, the use of copper to processing shrapnel, such as phosphorus copper shrapnel, beryllium copper shrapnel, can be through electroplating (gold, silver, nickel, tin, etc.) and other surface treatment methods to meet the requirements

The size of the edge value of metal stamping parts depends on which aspects?

The size of the edge value of the metal stamping parts mainly depends on the following aspects; 1. Mechanical properties of metal stamping materials. The edge value of hard materials can be smaller, and the edge value of soft materials and brittle materials is larger; 2, the thickness of the metal stamping parts material, the thicker the material, the greater the edge value; 3. Shape and size of blanking parts. The more complex the shape of the part, the smaller the radius of the fillet, and the larger the value of the edge; 4. Feeding and blocking methods; When feeding by hand, the edge value with side pressure device can be smaller. The edge value of spacing with side blades is smaller than that of spacing with blocking pins; 5, unloading mode; The edge value of elastic unloading is smaller than that of rigid unloading.

Oilstone polishing process for the surface of automotive stamping parts

As we all know, the entire car consists of four main processes: stamping, welding, painting and assembly. Then there are often many defects in the stamping process of car appearance parts that cannot be seen or touched, but after the paint is finished, such cars will be displayed in the market, and customers will feel that the car in front of them is not well-made, resulting in complaints and reduced purchase desire. Now is the time for professional inspection of these external parts to identify problems and provide the necessary data to support the quality improvement of individual parts. So, what do you rely on to identify these types of invisible and intangible problems? Next, I will tell you how to identify similar problems.
