Method for manufacturing a multimaterial component or construction

Abstract

A method for manufacturing a multimaterial component or construction, whereby a body (1, 7) is formed in said method of a basic material and at least one piece (3, 4, 5, 9) formed of a wear resistant material being joined to said body at a temperature of not more than 80 % of the lowest melting temperature of the materials to be joined. The invention also comprises the use of a multimaterial component or construction manufactured by means of said method.

Description

technical field [0001] The invention relates to the production of multi-material parts or components by producing wear parts of at least two different materials which are joined together to provide multi-material parts or components. Background technique [0002] Wear resistant components and components are used, for example, in plants for reducing the size of stone, construction or recycled materials. In these processes, the material to be pulverized that is compacted between the parts or impinges on the surface of the component or part wears the surface of the part, the degree of wear depends on the surface pressure of contact, the speed, the material properties of the part surface and the material being pulverized Physical properties such as compressive strength and tribological properties. In other words, the material to be crushed moves relative to and penetrates the surface of the part, which affects the wear on the part: the material moving relative to the surface of...

Problems solved by technology

[0006] In the wear part disclosed in the patent document JP2001165146, a more wear-resistant second material is joined for controlling the formation of wear, but only a joining method requiring precise shape and dimensional tolerances is disclosed for producing component, which is not justified in terms of cost-effectiveness

[0007] In addition, the patent document JP7323238 is aimed at the most preferred wear parts for the assembly of the components, in terms of functionality, it mounts the wear guards precisely formed to the body of the part, so that expensive body parts and wear guards cannot be omitted. multi-stage production process

[0008] Patent documents JP2001269589 and US 6,123,279 disclose wear parts, the purpose of which is to increase the wear resistance correspondingly by installing wear-resistant materials on the main body of the wear parts, but previously by using form-locking connections, and requiring applications Technical requirements complicate and cost-increasing forming methods for difficult-to-machine and form-hard wear protection materials, such as hard metals according to the following literature, capable of achieving the required dimensional and shape accuracy for assembly

[0009] Patent document P2004160360 additionally discloses that wear-resistant parts have to be formed (grooved) in a certain way for engagement, which is not beneficial technically and economically for the wear-resistant material used in the method according to this patent
