Sheet metal processing field and process

Sheet metal processing is actually the processing of metal products, and it is more to modify the metal sheets to achieve their use in many different places. It is processed in many ways, including stamping, cutting, cutting, etc. to change the properties and shape of the metal. The use of this processing technology can bring a lot of convenience to people’s lives, and also promote the development of China’s machinery manufacturing industry. For the sheet metal processing industry, it can be applied in many insights. There are many products around us that use sheet metal processing to achieve their value. For example, every household needs a door and a stainless steel window. There are also motor boxes, various control boxes, etc., which need to be completed by sheet metal processing. In addition, sheet metal processing is now moving in a large-scale direction. For example, the automotive industry and the shipbuilding industry, as well as various large-scale machining factories, use the advanced and efficient technology of sheet metal processing.
For the sheet metal processing industry. Their development prospects are bright and can be used more in the future, with the development of the economy and the continuous improvement of the machinery manufacturing industry.
Its demand is also growing. At this stage, what the sheet metal processing industry needs to do is to continuously improve its own technical level, increase its innovation capability, and strive to introduce advanced production equipment and expand production scale.

Sheet metal processing is the core technology that must be mastered by the technical staff of sheet metal parts. It is the key process flow for sheet metal crafts.
Sheet metal processing is the main parameters of traditional laser cutting, cold stamping production, bending and forming, and processing technology.
It also contains a variety of cold stamping die construction and processing technology main parameters, a variety of machine equipment principles and control methods, as well as new stamping die technology and new technology and new technology.
The production and processing of metal sheet materials for parts and components is called sheet metal processing.
How to choose raw materials? The raw materials commonly used for sheet metal processing are cold-rolled steel sheets, hot-rolled steel sheets, galvanized steel sheets, copper-copper, bare copper, beryllium copper, aluminum alloy sheets, and stainless steel sheets. The materials used are different, and the raw materials are usually different. Its main purpose and cost are taken into account.

1. The key electroplating process and painting parts of cold-rolled steel plate are low-cost and easy to form, and the thickness of raw materials is ≤4.3 mm.
2, hot-rolled steel sheet raw materials T ≥ 5.0 mm, are using electroplating process, painting parts, low cost, but difficult to form, the key use of tablet PC parts.
3. The galvanized steel plate electrolytic board is divided into N material and P material. The key of N material is not treated with metal surface, the cost is increased, and the P material is used for painting.
4, copper; key conductive materials, the metal surface treatment is electroless nickel, stainless steel, or unsolved, the cost increases.
5, aluminum alloy plate; usually with surface chromate, air oxidation, cost increase, gold plating, electroless nickel plating.
6, aluminum alloy profiles; cross-sectional structure analysis of the materials, many used in a variety of plug-in boxes. The metal surface is treated with an aluminum alloy plate.
7, stainless steel plate; the key is not used for all metal surface treatment, the cost increases.

In the metal processing technology, the opposite of thermal processing is cold working, which refers to the manufacturing process of plastic deformation of metal materials at a temperature lower than the work hardening temperature.
Such as cold rolling, cold drawing, cold forging, stamping die, cold extrusion and so on. The cold working process can increase the resistance of metal materials to deformation work, together with the production of metal products,
A combination of various metal materials can be used to exceed the purpose of improving compressive strength and strength, but cold working can reduce the plastic deformation of the metal material.
Usually, the metal material is firstly produced to lead to the corresponding solid model and then the cold working process is carried out. The cold working is suitable for the production of metal parts with small cross-section specifications, high production specifications and roughness specifications.

It is necessary to write the production process of the parts and components, first of all to understand the various technical standards of the parts drawings; then the drawing approval is the most critical step in the production process of the parts.

1. Check if the map is complete.
View association, label is not clear, complete, dimension unit.
3, the assembly line is associated, the assembly line specifies the weight of the heavyweight specifications.
4, the new boss picture difference.
5. Chinese translation of foreign language maps.
6, the table number conversion.
7, map puzzle feedback and buried.
8, raw materials.
9. Quality regulations and processing regulations.
12. The announcement of the sale of the drawings must be stamped with the quality management process.

The production process of sheet metal processing refers to the process of changing the appearance of parts, specifications, raw material characteristics or welding of spare parts in a regular order until the production and processing of sheet metal conforming to the specifications and specifications are produced. process,
For a lot of complicated parts, the production process usually has to go through the preparation of raw materials, construction stakeout, laser cutting blanks, molding and assembly lines, and so on.
And because the cold processing of sheet metal processing is often combined with the welding process of welding, metal material drilling, quenching and tempering and testing, resulting in detailed production and manufacturing processes,
Therefore, its production and processing production process often includes the contents of the production and processing process.

Sheet metal parts are such a comprehensive cold working process for sheet metal, including shearing, punching/cutting/compositing, folding, electric welding, riveting, patchwork, forming, and the like.
The production and processing of sheet metal materials is called sheet metal processing. Actually, for example, the use of panels can be used to make chimneys, stainless steel drums, automobile fuel tanks, ventilation ducts, elbows, roundabouts, tubular shapes, etc.
The key processes are cutting, sheet metal bending, bending, electric welding, riveting, etc., must have the expertise of geometry.
The contemporary sheet metal process includes filament switch power supply winding, fiber laser cutting, ultra-heavy production processing, metal material bonding, metal material drawing, plasma cutting machine,
Hardware mechanical welding, roll forming, sheet metal material bending, die forging, water jet laser cutting.
