Aluminum alloy stampings are characterized by low density, good conductivity and heat conductivity, and good corrosion resistance. The surface treatment of aluminum alloy can meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of products. The surface treatment commonly used for aluminum alloy includes spraying, painting, electroplating, anodizing, infiltration, oil spraying and sandblasting. 1. Spraying: It refers to the use of pressure or electrostatic force to attach paint or powder to the surface of the workpiece, so that the workpiece has the function of anti-corrosion and appearance decoration. 2. Baking paint: paint primer and finish on the base material, and send each coat of paint to the dust-free constant temperature baking room for baking. 3. Electroplating: the process of using electrolysis to make the surface of metal or other material parts adhere to a layer of metal film. It can prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance aesthetics. 4. Anodic oxidation: electrochemical oxidation of metal or alloy. The metal or alloy parts are used as anodes to form oxide films on their surfaces by electrolysis. The metal oxide film changes the surface state and properties, Such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting metal surface, etc. 5. Infiltration: the sealing medium (usually low viscosity liquid) is infiltrated into the micropores (fine seams) through natural infiltration (i.e. micropore self-priming), vacuum pumping and pressurization, and then the gap is filled The sealing medium in the gap is solidified by cooling or heating to seal the gap. 6. Oil spraying: spray paint on the product surface and dry it naturally. 7. Sand blasting: It uses compressed air as the power to form a high-speed jet beam to spray the materials (copper ore, quartz sand, carborundum, iron sand, sea sand) to the surface of the workpiece to be treated at a high speed, so as to change the appearance or shape of the external surface of the workpiece surface, Due to the impact and cutting effect of abrasive on the workpiece surface, the workpiece surface can obtain a certain degree of cleanliness and different roughness, and the mechanical properties of the workpiece surface can be improved, so the fatigue resistance of the workpiece is improved The adhesion between layers extends the durability of the coating film, and is also conducive to leveling and decoration of the coating.

Sheet metal parts refer to metal parts that have been processed by technology or machinery. Usually, metal raw materials are used to make them plastic deformation through process or stamping, and the shape formed usually meets the requirements of our rules. Molding can be divided into manual molding and mechanical molding. Process forming is usually used to make up for processing or trimming fields, and is rarely used. However, when processing some materials with disordered shapes or easy to deform, it is still inseparable from process molding. Up to now, sheet metal processing is mainly used to manufacture the shells of some packaging equipment, such as cabinets, car bodies, stainless steel cases, computer cases, etc. Because sheet metal includes stamping, bending, shearing and cutting, most of the sheet metal is used for processing metal sheets, and a small amount of sheet metal is used for manufacturing. Classification, processing and use of sheet metal parts I Sheet metal parts can generally be divided into three categories: 1. Flat plate: refers to ordinary flat punching shear piece. 2. Zigzag type: bend and weld after opening with CAD according to the planning drawing. 3. Forming type: regular surface or free-standing surface parts processed by stretching and other forming methods. These parts are formed by stamping and deformation of flat blank, which is very different from the parts processed by the common machining method. In the stamping processing method, zigzag deformation is the main processing method to make sheet metal parts have disordered spatial position relations. II Application scope of sheet metal processing: Sheet metal parts are widely used in electromechanical, light industry, automobile and other fields. It includes the following aspects: 1. Automobile field With the improvement of Chinese people's living standard, cars will enter thousands of households, which will promote the rapid development of the domestic automotive field. Auto manufacturers will outsource non base businesses while expanding production plans, so they will outsource some auto parts to Hefei sheet metal processing plant, which will supply, distribute and process automobiles. 2. Electronic communication field The electronic field is a rapidly developing field in recent years, and also a field where sheet metal was widely used at that time. Due to the characteristics of rapid technology update, diversified products and timely production in this field, this field is facing a greater risk impact from the mall. Most well-known companies at home and abroad outsource the sheet metal business and use limited funds for technology development. These companies include Lucent, Bell, ABB, Nokia, Siemens, Alstom, Philips and Huawei., Their outsourced sheet metal processing business is worth tens of billions of yuan every year. 3. Elevator field The elevator parts in other places are mostly sheet metal parts, and the types of elevator parts are complex. Each large elevator manufacturer has dozens of suppliers to distribute and process them. For example, Xizi Otis, Schindler, Mitsubishi, Hyundai, Hitachi and other famous elevator companies have their own stable suppliers, and their outsourced Guangzhou sheet metal business is about several billion yuan.

2、 Classification by operation combination degree According to the classification of different process combinations, stamping dies are divided into single process die, compound die, progressive die and transfer die. 1. Single process die Single process die refers to the die that can only complete one stamping process during the working process of the press. 2. Compound die In one stroke of the press, the compound die can complete two or more stamping processes at the same station at the same time. 3. Progressive die Progressive die is also called continuous die. This kind of die has two or more stations and can complete two or more stamping processes at different stations. 4. Transfer mode The transfer die can be transferred by a manipulator, which greatly improves the production efficiency, reduces the manufacturing cost and saves the material cost. The transfer die integrates the advantages of single process die and progressive die, and has the characteristics of quality safety, stability and reliability.  

Mechanical parts processing factory said, surface roughness is a key performance index reflecting the deviation of the surface micro geometry of the parts, is the key basis for detecting the quality of the surface layer of the parts; whether it is selected effectively, immediately related to the quality of goods, service life and product cost. The selection of mechanical parts surface roughness There are three kinds of ways, namely, measurement method, experimental method and analogy method. In the mechanical parts design program work, the most general use is the analog method, this method is simple, fast and reasonable. The use of analogical method must have ample references, the current variety of mechanical structure design guidelines are given a more comprehensive range of materials and references. The most common is the surface roughness that corresponds to the tolerance level. In general, the smaller the size tolerance requirements of mechanical parts, the smaller the surface roughness value of mechanical parts, but they will not have a fixed function of the relationship between them. For example, some equipment, instruments and equipment on the rocker, spindle and its health equipment, food machinery, some mechanical parts of the decorative surface, their surface requirements for production and processing is very smooth that is, the surface roughness requirements are very high, but the size tolerance requirements are very low. In general, there are size tolerance requirements of the parts, the tolerance level and surface roughness value in the middle or have a certain correspondence.   The above is to explain the choice of surface roughness of mechanical parts, hope to see can help you!

Precision machining factory said, machinery is to help reduce the difficulty of work or save energy tools and equipment, like chopsticks, brooms and its tweezers a class of things can be called machinery, they are simple machinery. And complicated machinery is composed of two kinds or two types of simple machinery. Generally, this more complex machinery is called machines. From the point of view of construction and fitness movement, there is no difference between the mechanism and the machine, and it is generally called a machine. The concept of mechanism and machine is derived from mechanical hydraulics and belongs to the most important definitions of contemporary mechanical design fundamentals, while the current definition of machinery in Chinese is mostly derived from the Japanese word "machine". All machines and mechanisms with a clear system of motion are collectively referred to. For example: CNC lathe, big tractor, etc. Mechanical engineering is a course of application based on relevant scientific and technical research as a theoretical basis, integrating the accumulated experience of process work in practice, scientific research and processing in the design and development, manufacturing, installation, application and repair of various types of machinery in the basic theory and specific conditions. The development of each engineering aspect provides for a matching development of mechanical engineering, and all must mechanical engineering give the necessary machinery. The invention and soundness of some machinery will cause the occurrence and development of new engineering design and new industrial chain. For example, the success of the production of medium and large transmission equipment has led to the creation of power supply systems; the invention of locomotives has led to the prevalence of railroad engineering and the railway line industry; the invention and progress of gas turbines, gas turbines, rocket engines, and the development of aircraft and spacecraft has led to the prevalence of aviation and aerospace engineering; the development of Korak facilities has led to the success of many new types of synthetic chemical engineering.   The above is the definition of precision machining factory for you to explain the machinery, hope to read to help you!
