Brief introduction of roll forming process for roll parts manufacturers


  Roll forming process for roll parts manufacturers

 

  Roll forming technology refers to the technology that relies on the plastic mobile network characteristics of traditional materials and adopts the principle of rolling extrusion to form various complex parts in the process.

  Introduction to the process of rolling parts manufacturers

 

  Roller pressure deformation is a kind of linear contact, which is carried out step by step continuously. The required deformation force is very small, and one stroke can produce one or more workpieces. The roll forming process and cutting and grinding process not only have high production efficiency, high material saving, high product strength and stable quality, this process is especially suitable for processing the length of cutting workpieces, especially for rolling parts manufacturers with an annual output of millions of quality The product is advantageous in adopting the roll forming process, and the economic benefit is remarkable.

 

  Roll forming began in Europe around the 1960s. The roll forming tool of the present invention has the advantages of high production efficiency, material saving, and increased product strength, and is not only applicable to the threaded fastener industry, but also industrial sectors such as automobiles and bicycles to process parts with complex shapes by the roll forming process. With the advancement of technology and the development of production, roll forming technology has been paid more and more attention by people.

 

  Product features of rolling parts manufacturers

 

  Compared with cutting and grinding technology, roll forming technology not only has high production efficiency and saves materials, but also has high strength and stable quality. Especially for large-scale products with an annual output of one million pieces, roll forming technology is most beneficial and economically beneficial. Also for considerable.

 

  Material

 

  The rolling process is a cold forging process. There are many materials that can be rolled. Among them, low carbon steel is more commonly used in roll forming, while non-ferrous metals are more suitable for roll forming.

 

  equipment

 

  Roll-formed parts are generally produced by forging blanks through a cold heading machine, and then processed by a thread rolling machine using rolling technology. The equipment that can be selected for thread mechanical rolling and roll forming includes: various reciprocating motion flat thread rolling machines, planetary thread rolling machines, two-cylindrical thread rolling machines and three-cylindrical thread rolling machines, etc. The reciprocating flat-plate thread rolling machine is commonly used in roll forming. Therefore, for manufacturers and enterprises equipped with cold heading machines and thread rolling machines, it is only a matter of designing molds for roll forming processes.

 

  method

 

  The movable wire board is formed by relative reciprocating motion of the fixed wire board. Roll dies are different structural designs of wire plate rolls on the workpiece. Various threads, collars, flanges, end chamfers and various grooves and other shapes as required.

 

  mold

 

  Roll forming is more complex and demanding than thread rolling. The mold design is to design the spinning plate into one or several sections according to the different shapes of the workpiece, which can be synchronous or graded. When the diameters of the billets along the axis are the same or basically the same, synchronous roll forming can be used; when the diameters of the billets along the axis are different, several diameters of different structures need to be rolled, and graded roll forming is used. Usually, it can be formed by one roll, and complex shapes can also be formed by two rolls.
