Understand the role and significance of sheet metal processing technology, understand sheet metal processing

It can be said that sheet metal processing covers all aspects of our lives, covering aviation, transportation, railway transportation, automobiles, computer cases, communication boxes, medical equipment, instruments and other major fields. Visible sheet metal processing is very important for us.

Among them, the spraying process of the sheet metal processing surface is of great significance to the sheet metal processing, and the surface spraying has a protective effect on the sheet metal. Sheet metal cabinets, equipment shells, etc. are exposed to the air and will not be oxidized under the protection of the coating, so they will not rust and have the function of waterproof and rust prevention.

We produce sheet metal shells with high precision and excellent appearance. The precision concept of sheet metal processing parts is silk, and its appearance requirements are the same as those of automobile surfaces.

Sheet metal processing products use epoxy mica iron intermediate paint, which is used in combination with epoxy zinc-rich primer as a durable anti-corrosion coating transition layer. Its role is to enhance the sealing and corrosion resistance of the composite coating. Used for anti-corrosion and anti-rust primer. The coating film is strong, has good adhesion and sealing, and has good compatibility with the front and back coatings. Its composition is: epoxy resin and curing agent, parent iron oxide and anti-rust pigment.

The commonly used materials in sheet metal processing are cold rolled plate, galvanized plate, copper plate, aluminum plate, stainless steel plate, aluminum, etc. They have different functions. As for how to choose, generally need to consider from the use and cost. Sheet metal parts are sheet metal hardware, that is, parts that can be processed by stamping, bending, stretching and other methods. The general definition is a part with a constant thickness during processing. For example, corresponding to castings, forgings and machined parts, the iron shell outside the car is a metal plate, and some stainless steel cabinets are also metal plates.

For a long time, sheet metal chassis processing has become a more prominent form of processing in the processing industry. Today, many electronic product housings are made of thin metal plates that are strong and have a long service life. So, what are the precautions for sheet metal processing chassis?

1. After bending, riveting and other processes, the surface treatment of the workpiece is completed. For different boards, the surface treatment method is different. After cold plate processing, surface plating is usually performed. After plating, do not spray. Phosphating treatment is carried out first, and then spraying. Clean and wipe off the grease on the surface of the board after degreasing.

2. In the sheet metal chassis processing, the next process is usually entered after the blanking is completed, and different workpieces enter the corresponding process according to the processing requirements.

Matters needing attention in the development of sheet metal processing industry

In today's economic situation, the development of many industries is difficult. The development of the sheet metal processing industry naturally also has many obstacles. In order to break through the shackles of the existing economic situation, we must grasp every step of our own development. Strive to achieve the sustainable development of the industry, for the sheet metal processing industry, if they want to occupy their own market in the existing market environment, then they must know what they should change and achieve a breakthrough in their own industry.

What are the requirements of precision sheet metal processing for processing materials?

Different precision sheet metal shell need to use different precision sheet metal processing materials to process, is to use stainless steel, or ordinary cold rolled plate, which need to consider the requirements of the precision sheet metal parts to be processed to determine.

What is the process flow of sheet metal processing?

After the drawings are obtained, different blanking methods are selected according to the expansion drawings and batches, including laser, numerical control punching machine, plate shearing, mold and other methods, and then the corresponding expansion is made according to the drawings. CNC punching machine is affected by the cutting tool, for the processing of some special-shaped workpieces and irregular holes, there will be large burrs on the edge, which will have a certain impact on the accuracy of the workpiece. Laser processing has no tool limit and smooth section, which is suitable for the processing of special-shaped workpieces, but it takes a long time to process small workpieces. The workbench is placed next to the numerical control and laser, which is conducive to the processing of the sheet metal on the machine and reduces the workload of lifting the sheet. Some available edge materials are placed in designated places to provide materials for bending test molds.
