Rodamientos estampados
Los rodamientos de estampación son rodamientos de agujas fabricados con tecnología de estampado. El estampado es un proceso de fabricación que utiliza troqueles y prensas para procesar placas de metal en la forma deseada.AINEson fabricantes de rodamientos de alta calidad con unVariedad de rodamientosto supply.
Stamping bearings are a forming processing method that uses presses and dies to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping bearing stampings) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips.
Los rodamientos de estampación tienen las siguientes ventajas:
1. Low cost: Stamping technology is an efficient manufacturing process, so the cost of stamping bearings is lower than that of traditional needle roller bearings.
2. Light weight: The outer ring of the stamping bearing is stamped from thin steel plates, so it is light in weight.
3. Compact structure: The cross-sectional height of the stamping bearing is small, so the structure is compact.
Los rodamientos estampados son adecuados para una variedad de aplicaciones
Incluido: 1. Automóviles: Los rodamientos estampados se utilizan en varias partes de los automóviles, como motores, cajas de cambios y suspensiones. 2. Electrodomésticos: Los rodamientos estampados se utilizan en diversos electrodomésticos, como lavadoras, secadoras y aires acondicionados. 3. Maquinaria industrial: Los rodamientos estampados se utilizan en diversas maquinarias industriales, como bombas, ventiladores y cintas transportadoras. 4. Equipo de oficina: Los rodamientos estampados se utilizan en varios equipos de oficina, como impresoras, fotocopiadoras y escáneres.
Proceso de estampado
Stamped bearings are generally no longer cut, or only require a small amount of cutting. The precision and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is small.
Stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press, realizing fully automatic production from strip unwinding, leveling, punching to forming and finishing. High production efficiency, good working conditions, low production costs, generally hundreds of pieces can be produced per minute.
Stamping is mainly classified by process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line while ensuring the quality requirements of the separation section. The purpose of the forming process is to make the sheet material plastically deform without breaking the blank, and make a workpiece of the required shape and size. In actual production, multiple processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and straightening are several major stamping processes.
