Description

DESCRIÇÃO

I

Os bicos em metal duro (carboneto de tungsténio ou carbo neto de boro) para decapagem por jacto têm o revestiment exterior em aço.

Devido, sobretudo, ao mau manuseamento do bico, este que bra facilmente a parte interior de metal duro (carboneto de tungsténio ou carboneto de boro) encurtando, deste modo, a vida útil da peça.

Uma vez danificada a parte interior do bico, este deixa de servir, não restando outra alternativa senão a sua substituição, acarretando prejuízos.

II

0 objecto da presente invenção consiste exactamente em

ϊ

obviar à inutilização precoce dos bicos, motivada pelo

seu mau manuseamento.

Assim, eliminando por completo a possibilidade das fracturas, torna-se possível utilizar totalmente os bicos enquanto durar o núcleo em metal duro (carboneto de tungsténio ou carboneto de boro).

Daqui ressalta que pelos cálculos e experiências já realizadas, a duração da peça pode ser aumentada em 100%

Além disso, o produto à saída não sai significativamente

mais caro.

III

PROCESSO DE FABRICO

0 núcleo continua a ser em metal duro (carboneto de tungsténio ou carboneto de boro) tal como os que se encontram

no mercado.

No entanto, de harmonia com a presente invenção, este núcleo vai ser sujeito às seguintes operações:

1—Revestimento exterior do núcleo de metal duro com

alumínio ou zamac ou outras ligas leves fundidas.

22.- Junção da cabeça roscada ou com o formato desejado

pelos clientes em aço, alumínio ou outro metal apropriado .

- 3 32.- Vulcanização ou injecção exterior de borracha e/ou ' matérias plásticas.

Este material tem que ser apropriado de forma a garantir a indeformabilidade, a resistência e o amortecimento das

pancadas .

DESCRIPTION

I

Hard carbide (tungsten carbide or boron carbide) nozzles for jet blasting have the outer steel coating.

Due in particular to improper handling of the nozzle, this easily brackets the inner part of the carbide (tungsten carbide or boron carbide) thereby shortening the service life of the part.

Once the inner part of the nozzle is damaged, it stops serving, with no alternative but replacement, causing damages.

II

The object of the present invention consists precisely of

(i.e.

to obviate the early decomposition of the nozzles,

its bad handling.

Thus, by completely eliminating the possibility of fractures, it becomes possible to fully utilize the nozzles while the hard carbide core (tungsten carbide or boron carbide) lasts.

From here, it should be noted that by the calculations and experiments already carried out, the duration of the piece can be increased by 100%

In addition, the output product does not significantly

more expensive.

III

MANUFACTURING PROCESS

The core continues to be hard metal (tungsten carbide or boron carbide) such as those found

in the market.

However, in accordance with the present invention, this core will be subjected to the following operations:

1-Outer coating of the carbide core with

aluminum or zamac or other fused light alloys.

2 2 .- Joint of the threaded head or with the desired shape

customers in steel, aluminum or other suitable metal.

- 3 3 2 .- Vulcanization or external injection of rubber and / or plastics.

This material must be suitable in order to guarantee the undeformability, the resistance and the damping of the

blows
