Abstract
The utility model discloses a kind of Combined hard-alloy composite ring, described collars is ring-type, comprise set gradually from outside to inside skin, intermediate layer and internal layer, described intermediate layer is compounded in described outer inner surface by laser melting coating, and described internal layer is connected with described intermediate layer interference fit.This collars solves the process difficulties of carbide alloy compound, and when also solving carbide alloy and ferrous materials mechanical combination, magnitude of interference great Yi produces cracked problem.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of Combined hard-alloy composite ring.
Background technology
Cemented carbide composite roll collar was based on the problem adopting casting technique to solve carbide ring and cast iron or cast steel how metallurgical binding in the past, brought the change of the complexity of manufacturing process and the serviceability of carbide ring.And carbide alloy and ferrous materials mechanical combination time magnitude of interference great Yi produce cracked problem.
Utility model content
The utility model makes improvement for above-mentioned Problems existing, and namely the technical problems to be solved in the utility model is to provide a kind of Combined hard-alloy composite ring, and structure is made up of three layers of unlike material.Skin is carbide alloy; Arrange intermediate layer and reach metallurgical binding with outer by laser melting coating, the bond strength of land is larger; Internal layer has higher intensity and good wearability, is convenient to combine with mandrel, and this collars structure can save more outer material.
In order to solve the problems of the technologies described above, the utility model proposes so a kind of Combined hard-alloy composite ring, described collars is ring-type, comprise set gradually from outside to inside skin, intermediate layer and internal layer, described intermediate layer and described skin carry out metallurgical binding by laser melting coating, and mechanical combination is carried out by interference fit in described internal layer and described intermediate layer.
Further, described skin is circular or irregular ring-type.
Further, described skin is that carbide alloy is outer, and described intermediate layer is ferrous alloy or Nickel-base Alloy Interlayer, and described internal layer is steel alloy internal layer.
Further, described intermediate layer and skin carry out metallurgical binding by laser melting coating.
Further, described internal layer and described intermediate layer complete interference fit by hot charging or cold charge.
Further, described collars external diameter is 150-450mm, and described outer field thickness is 10-30mm, and the thickness in described intermediate layer is 5-15mm.
Preferably, described collars external diameter is 340mm, and described outer field thickness is 15mm, and the thickness in described intermediate layer is 7.5mm.
Preferably, described collars external diameter is 380mm, and described outer field thickness is 25mm, and the thickness in described intermediate layer is 10mm.
The beneficial effects of the utility model:
The present invention adopts laser melting and coating process cladding ferrous alloy or nickel-base alloy on hard alloy substrate, carbide alloy is working surface, there is characteristic and the serviceability of the carbide alloy that traditional handicraft is produced, ferrous alloy or form metallurgical binding between nickel-base alloy and carbide alloy, has possessed the characteristic with other iron and steel material quality interference fit.This technical scheme solves the process difficulties of carbide alloy compound, and when also solving carbide alloy and ferrous materials mechanical combination, magnitude of interference great Yi produces cracked problem.And the skin of this collars can be designed as various irregularly shaped, can reduce the use of outer material.
