Processo de Fabricação do Alicate
Summary
TLDRThe script outlines the manufacturing process of a wrench, starting with the heating and cutting of a metal billet. It then describes hot compression molding to shape the wrench, followed by secondary hot compression and cooling. Chemical and thermal treatments are applied to relieve stress and harden the steel. The wrench undergoes abrasive polishing to refine its edges. Cold compression ensures the wrench's shape, and drilling creates holes for assembly. Broaching is used to form teeth and remove burrs. Finally, the wrench is tempered to enhance hardness and durability, and a finishing process smooths the surface, completing the wrench's production.
Takeaways

Q & A
What is the initial material used for manufacturing the pliers?
-The initial material used for manufacturing the pliers is a billet, which is a solid piece of metal.
What is the purpose of the linear movement in the initial stage of the process?
-The linear movement is used to cut the billet into equal lengths, ensuring uniformity for the subsequent manufacturing steps.
How are the cut billet pieces heated in the manufacturing process?
-The cut billet pieces are heated in a machine called a hot compression machine, which shapes them into the desired form.
What happens during the second hot compression process?
-During the second hot compression, the heated billet receives another function, which further refines its shape to resemble one side of the pliers.
Why are the pliers symmetrical after the hot compression processes?
-The pliers are symmetrical because the hot compression processes are designed to create a mirror image on both sides, ensuring that each half of the pliers is identical.
What is the purpose of the chemical and thermal treatment in the pliers manufacturing process?
-The chemical and thermal treatment is used to relieve stresses in the steel and to attract refractory materials, ensuring uniform temperature distribution across the piece.
How does the tumbling process contribute to the finishing of the pliers?
-The tumbling process uses abrasive materials to round off the corners and polish the pliers. The piece rotates in constant movement, and the abrasive chips polish the pliers.
What is the purpose of the cold compression after the tumbling process?
-The cold compression is used to ensure the final shape and size of the pliers, with the upper part of the machine pressing down on the piece to guarantee the form.
How is the hole for the pivot created in the pliers?
-The hole for the pivot is created using a drilling process, where the pliers are held in place and a drill bit removes the material to form the hole.
What is the function of the broaching process in the manufacturing of pliers?
-The broaching process is used to create the serrated edges or teeth on the jaws of the pliers. It involves a tool with teeth that move rotationally and linearly, cutting into the pliers to form the serrations.
What is the final process that the pliers undergo before they are considered complete?
-The final process the pliers undergo is tempering, which increases the hardness and resistance of the piece. This involves heating to organize the metal crystals (austenitization), followed by rapid cooling to achieve a martensitic structure, and finally, a process called burnishing to produce smooth surfaces.

🔨 Manufacturing Process of a Knife
João Vitor Irei introduces the knife manufacturing process. It starts with a steel billet being cut into bars. These bars are heated and then compressed using a hot compression machine. The heated billet is shaped into the base form of the knife. After the initial compression, the knife goes through a second hot compression to refine its shape. The knife then undergoes chemical and thermal treatment in a closed furnace to relieve stress and ensure uniform temperature. It is then polished using abrasive materials, specifically tumbling, which involves rotating the knife against abrasive chips to smoothen the edges and corners. Cold compression is applied to ensure the knife retains its shape. The script also mentions drilling and threading processes, where holes are made for pins and screws to secure the knife components. Finally, the knife undergoes a tempering process to increase hardness and resistance, involving heating for austenitization, rapid cooling for martensitic structure, and finishing with a grinding process for smooth surfaces.

o Olá meu nome é João Vitor Irei
apresentar o processo de fabricação do
alicate inicialmente a gente tem a costa
do lingote unicode vem aqui no movimento
linear depois de certa medida ver opção
superior fazendo o corte entendeu que os
negócios são iguais posteriormente eles
são aquecidos
Tá certo e depois tem uma máquina de
compressão a quente onde o povo são
infelizes inferior é estático Mas ele
tem uma forma aqui você pode precisar e
o posição superior é levantado e ele
desse com a pressão com a velocidade
para impactar se esse lingote quente
você vê que legal de recebe da forma do
da base não posteriormente ele vai para
uma segunda ou segunda compressão a
quente e o e terminando o né ele recebe
outro função o só vem entrar a retirar
as rebarbas sucesso você vê que ele dá
ele já tá com a forma de um lado dos
Aliados os aliados nesse caso são
simétricos então ele já tem par
a gostar a mente vai para tratamento
químicos e térmicos onde esse forno só
fechado serve para os a livros das
tensões revestido em aço e como atrair
as refratados para para manter a
temperatura igual em todos os pontos
e posteriormente ele vai para um
polimento por material abrasivo que no
caso é o tamboreamento tomar lamenta ele
serve para arredondar os cantos por meio
do chips abrasivos onde que fica em
contrato direto com a peça Enquanto
autor a mental a pessoa fica
rotacionando em constante movimento e
chips abrasivos fica polino quando as
vantagens polimento do tamboreamento
aqui um ciclo e consegue levar muitas
peças
o amor pode verificar aí depois vem a
compressão a frio simplesmente para
garantir a forma porção superior cai
desce na peça garantindo a fórmula 1
ó ó
Oi gente viu aí que tem o processo de
furação o furo passante você vê que ele
colocou alicate ali Aí tem essas crenças
que Prenderam o furo passou para furo
passante e ele consegue remover o cavaco
nesse caso vai ter um furo
o funcionamento temos o fresamento que
sai para criar as estrias o alicate os
dentinhos na boca do alicate a frase a
ver com o movimento rotacional e linear
passando pelas por um lados do alicate
fazendo essa esses dentes e por último
temos o fresamento para remover os
cavacos seria o outro lado do alicate
retirando todas as suas barbas
Oi e a Furação no caso que seria o outro
lado do alicate não mesmo a função
fazendo furo passante Você viu que ele
passa totalmente você consegue analisar
para aqui por essa imagem que temos um
furo passante aqui ó nas dois lados da
peça posteriormente temos a montagem
onde a máquina desce colocando um pino
um parafuso um alicate justamente para
assegurar e a outra máquina ela parafuso
né onde ela rota aciona o furo do
parafuso até certo.
e finalizando alicate está pronto mas
ele vai passar o tempo processo de
têmpera que tem a função de aumentar a
sua dureza e a sua resistência da peça
primeira etapa da tempo é o aquecimento
ele serve para organizar os cristais do
Metal chamado austenitização e
posteriormente um resfriamento rápido
para obter a estrutura marquesita e para
finalizar ele para passar pelo lixamento
para produzir superfícies lisas a
máquina se chamar lixadeira e ela tem a
função de lixar a peça o acabamento
final
e para a pés
e o alicate e é isso obrigado pela
