The so -called automated equipment refers to machines that can be automatically run according to the established procedures or instructions without intervention, including standard devices and non -standard devices. It is a combination of several institutions that can realize different functions. The so -called institution refers to a mechanical device that can achieve a specific action that can achieve a specific action. This article introduces the characteristics and selection of commonly used materials in processing components in automation equipment.

SUJ2 is a high-carbon chromium bearing steel, which can be treated completely, and the hardness can reach HRC58-61. It has the abrasion resistance of the bearings, also strengthens the steel, has good processing, and can be processed directly. Common surface treatment methods are: hard chrome.



Uses: For general plastic molds, machine tool bearings, steel balls, rollers, shaft sleeves, guide columns, etc.



6061
Features: The common drawing is 6061, the density is 2.75g/cm, and the price is about 22 yuan/kg. The main alloy elements of 6061 aluminum alloy are magnesium and silicon. They have excellent characteristics such as medium strength, excellent processing performance, excellent welding characteristics, good corrosion resistance, high toughness, no deformation after processing, and good oxidation effects. Common surface treatment methods are: sandblasting, oxidation (this color anode oxidation, hard anode oxidation), and surface drawing.



Uses: widely used in structures that require a certain intensity and have certain requirements for loads, such as industrial robotic claw claws, feeding and moving materials and other sports components.



SUS304
Features: The common drawings are identified as SUS304, density is 7.93g/cm, and the price is about 25 yuan/kg. SUS304 is austenite stainless steel. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It has good thermal processability such as stamping and bending. Not good, sticky knife, and the machine can use SUS303.



Uses: Widely used in the furniture decoration industry and the food medical industry.



SPCC
Features: Common drawings are identified as SPCC with a density of 7.85g/cm, and the price is about 5 yuan/kg. SPCC is a cold -rolled carbon steel sheet. It has good processing performance and welding performance. The common surface treatment methods are: spray (paint) and so on.



Uses: Commonly used for some installation brackets that do not require accuracy requirements such as the rack panels, door panels, sensors, and drag chains in the device.



Racing steel
Features: The common drawings are identified as POM and Sai Steel with a density of 1.45g/cm and the price is about 23 yuan/kg. Sai Gang, also known as polydeons, belongs to plastic, has a low density, has good wear resistance and stability. It is divided into ordinary Steel and anti -static electric steel (42 yuan/kg). , To indicate the color and whether to prevent static.



Uses: It is often used for structural parts with low mechanical requirements. Anti -static rating steel is often used in some healing and fixtures.



Electric wood
Features: Common drawings are identified as electric wood with density of 1.3g/cm and the price is about 24 yuan/kg. Electric wood has no water absorption, non -conductivity, high temperature resistance, high strength, high corrosion resistance, and good plasticity. Adding anti -static materials can be called anti -static electric wood (42 yuan/kg).



Uses: Commonly used for manufacturing electrical materials, such as switching, light heads, headphones, telephone cases, instruments, etc., probe boards, distribution boards, fixtures, and treatments in the device.



Youli Jiao
Features: The common drawings are identified as Youli Glossom and PU, with a density of 1.13g/cm, and the price is about 30 yuan/kg. Youli glue, also known as polyurethane PU elastic body, has the characteristics of buffer, mute, shock absorption, abrasion resistance, high temperature resistance and other characteristics. It has the rigidity of plastic and the elasticity of rubber. Between use, it is necessary to mark the hardness.
