Precision hardware processing technology and operating specifications

Precision hardware can be cut according to production needs, and then some small parts can be processed by gong cutting or CNC processing. Precision hardware containers must be made by using a cutting punch, followed by welding, sanding, and oil spraying before the parts are made. The following editor will introduce you to the content of precision hardware processing technology and operating specifications. Welcome to read!

Causes and Solutions of Scratches on the Bending Surface of Metal Stamping Parts

When continuous operations are performed on soft materials such as copper and aluminum alloys for stamping and bending, metal particles or residues can easily adhere to the surface of the work site, causing large scratches on the object. At this time, carefully analyze the shape of the work site, lubricating oil, and other conditions to avoid generating particles and residues in the blank, causing scratches.

What are the characteristics of precision metal stamping parts processing

Precision metal stamping processing refers to a technology that uses precision molds and advanced technological methods to punch or stretch metal plates and strips. It includes three types: cold stamping, warm extrusion, and hot stamping. Cold stamping is the most widely used technology, accounting for about 80% of the entire production process, warm extrusion accounts for 10%, and hot stamping only accounts for 10%. Up to now, there has not been a relatively complete definition of stamping parts. According to a definition in a foreign journal, it can be defined as: sheet metal is a comprehensive cold working process for metal sheets (usually less than 6mm), including shearing, punching/cutting/laminating, folding, welding, riveting, splicing, and molding (such as automotive body). Its prominent feature is the consistent thickness of the same part.

What are the main categories of molds

Moulds (m ú j ù) are known as the "mother of industry". In industrial production, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, and other methods. In short, a mold is a tool used to make molded items, which primarily processes the shape of the item by changing the physical state of the material being molded. There are many types of molds, which can be divided into: ① A mold for working metal.

Introduction to Common Processes in Sheet Metal Processing

With the progress of industry, sheet metal parts are widely used in our daily life. All kinds of household appliances need to use a variety of sheet metal parts. Each link in the sheet metal processing process is very important, and any problem in one link will affect the processing quality of the product. Therefore, every detail in the sheet metal processing process must be perfect, so that qualified sheet metal parts can be produced. Sheet metal processing and stretching process: During the processing of sheet metal, it is sometimes necessary to unfold the stamping material, known as stretching. Stretching is mainly aimed at sample materials with unique requirements. The material thickness changes after stretching. Generally speaking, the center of the bottom maintains the original thickness, the material at the bottom corner becomes thinner, the material at the top near the flange becomes thicker, and the material at the corner around the rectangular stretch piece becomes thicker. Sheet metal processing and forming process:

Development status of domestic sheet metal processing industry

The sheet metal processing industry is closely related to our lives. Although it accounts for only 20% to 30% of the proportion compared to metal processing, almost all manufacturing industries involve sheet metal processing, such as the electric power industry, machine tool and machine industry, food machinery, textiles, electrical appliances, instrumentation, equipment, electricity, network, sanitation, cabinet sanitation, office work, and so on; Specific products include: high and low voltage cabinets, control cabinets, control boxes, electrical boxes, trash cans, equipment and machine casings, network cabinets, computer cases, electrical instrument casings, stainless steel kitchen and bathroom equipment, office furniture products, subway products, and so on.

Two Cases of Rust on Stainless Steel Chassis and Cabinet

Stainless steel cabinets are made of stainless steel as the main material, which has outstanding functions in terms of rust prevention and corrosion. They can be kept as they are in both acidic and alkaline environments, but this does not mean that stainless steel cabinets are truly "rust free". Common cases of "rust" in stainless steel cabinets include intergranular corrosion and uniform corrosion. 1、 Intergranular corrosion is a type of localized corrosion. Corrosion that propagates inwardly along the boundaries between metal grains. This is mainly due to differences in chemical composition between the surface and interior of the grains, as well as the presence of impurities or internal stresses at the grain boundaries. Intergranular corrosion destroys intergranular bonding, greatly reducing the mechanical strength of stainless steel, and weakening its mechanical properties. "After corrosion occurs, the surfaces of metals and alloys still maintain a certain metallic luster, with no sign of damage. However, the intergranular bonding force is significantly weakened, and the mechanical properties deteriorate, making them unable to withstand percussion. Therefore, it is a very dangerous type of corrosion.". Intergranular corrosion of stainless steel welds is a major issue in chassis and cabinets.

What materials are commonly used in sheet metal processing

Sheet metal processing refers to the processing of metal plates to obtain the desired appearance, which mainly involves the processing of sheet metal chassis, sheet metal server cabinets, and various mechanical equipment internal structures and chassis sheet metal parts. Many devices in daily life are processed in that way, such as bank registration machines, automatic teller machines, product vending machines commonly used on the streets, and computer and display boxes that are made from sheet metal processing. At the same time, in order to consider the practicality of the product, the plates used in general sheet metal processing mainly include the following categories: 1. Plain Cold Rolled Steel Sheet (SPCC) Ordinary cold rolled steel plate is a thick steel plate, tube, or sheet material that is continuously cold rolled into a specified wall thickness by a cold rolling mill. The surface layer does not have safety protection and is very prone to oxidation and corrosion. Therefore, safety protection measures such as spraying and electroplating processes should be taken before application. 2. Galvanized steel plate
