No processo de design e produção de automóveis estampagem dies, not only must practically meet the technical requirements of body parts, but also attach great importance to the mechanical equipment,

operation methods, transportation methods, and mold installations used in the design and manufacturing process. and waste disposal issues. Automobile Stamping Dies

1. Factors Considered in Estampagem Die Automobile Stamping Dies

• Preço 

In the process of designing and manufacturing automotive stamping dies, the first factor to consider is its price, which will affect the final sales of the product. Automobile Stamping Dies

• Qualidade

The level of automobile safety factor is usually determined by stamping dies, therefore, the quality of stamping dies will also directly affect product sales. Automobile Stamping Dies

• humanização

No processo de projeto de matriz de estampagem de automóveis, a humanização também é um fator importante que deve ser considerado, devendo-se atentar para sua manutenção e reparo para que a substituibilidade parcial da matriz possa ser refletida com mais força. Para aquelas peças com uma frequência de substituição relativamente alta, padrões mais elevados devem ser estabelecidos no processo de projeto, o que é extremamente benéfico tanto para o fornecimento quanto para a compra.

• Matérias-primas

Geralmente liga de aço ou liga de ferro fundido.

• Precisão

In mold production, precision will directly affect the degree of fit between parts after assembly, as well as the presentation of gap consistency. Automobile Stamping Dies

2. Manutenção e reparo de matriz de estampagem automotiva

Due to the harsh working environment of automotive stamping dies, during use, the working parts, fitting parts, and sliding positions are often worn or even damaged. At the same time, due to factors such as complex mold design and manufacturing process, high precision, long cycle time, and high cost, it is necessary to repair problems in time during use, so as to ensure accuracy and improve service life. Although the maintenance and repair of automobile stamping dies are very complicated, there are mainly the following seven situations for frequent failures and maintenance methods: Automobile Stamping Dies

• Flanging Deformed Automobile Stamping Dies

In the process of flanging and shaping, the deformation of the workpiece often occurs, especially the deformation in the surface part, which has a great impact on the quality of the workpiece.

The general solution is to increase the pressing force. If it is a spring-pressing material, the method of adding a spring can be used. For the upper air cushion pressing material, the method of increasing the air cushion force is usually used;

if there is still local deformation after increasing the pressure, it is necessary to Find out the specific problems, check whether there is a local depression on the binder surface, etc. At this time, the method of welding and repairing the binder can be used; after the binder is welded, it will be researched and matched with the lower surface of the mold.

• Corte de Borda Automobile Stamping Dies

Este é um dos problemas mais comuns que ocorrem durante o uso de moldes. Se o lascamento do fio da navalha for muito pequeno, geralmente é necessário retificar o fio lascado maior com uma esmerilhadeira e soldá-lo com a vareta de solda correspondente para garantir que a solda fique firme e não seja fácil lascar novamente.

• Escovar

Ocorre principalmente em processos como trefilação, conformação e flangeamento. Para comparar a peça de trabalho para encontrar a posição de rugosidade correspondente do molde, empurre-a suavemente com uma pedra de óleo, preste atenção ao tamanho uniforme dos cantos arredondados e depois faça o polimento com lixa fina.

• Fita de Aparar e Perfurar Automobile Stamping Dies

Due to the abnormality of the pressing or unloading device of the mold during trimming or punching, the trimming and punching carry material. At this time, it is also necessary to find the corresponding part of the mold according to the position of the part.

If there is any abnormality in the mold pressing stripper, repair the welding of the pressing plate. If there is no problem with the mold-pressing stripping plate, you can check the mold knife block Whether there is a hair-pulling phenomenon.

• Desperdício Contínuo

Como o operador não limpou os resíduos a tempo durante o processo de produção, o acúmulo de resíduos foi causado e, finalmente, a faca de resíduos foi quebrada sob a pressão do bloco de facas de corte superior, resultando no corte contínuo de resíduos. O método de seu reparo é semelhante ao de corte de borda e lascamento.

• Falha

Due to the gap between the cutting edges of the mold, the burr is too large when the workpiece is trimmed, punched, and blanked. When the gap is large, the trimming and punching process adopts the method of trimming the die without moving the punch, and in the blanking process, the method of trimming the die without changing the die is used.

If the gap is small, it should be adjusted according to the size of the mold gap to ensure a reasonable gap. For the trimming, and punching die, the method of placing the gap in the die is adopted, while for the blanking die, the method of enlarging the punch should be adopted, so as to ensure that the size of the part remains unchanged before and after repair.

• Resíduos de perfuração entupidos

O desperdício de perfuração é bloqueado devido ao caminho de desperdício não liso, o afunilamento reverso do caminho de desperdício e o desperdício não sendo limpo a tempo. Para garantir que os lados A e B estejam em um estado liso e de diâmetro igual, é possível garantir que os resíduos não sejam bloqueados.

Automobile stamping dies, also known as automotive stamping dies or metal stamping dies, are specialized tools used in the manufacturing of automotive parts and components. These dies are an essential part of the metal stamping process, which is widely used in the automotive industry to produce various sheet metal parts and components, such as body panels, chassis parts, brackets, and more.

Here are some key aspects and information about automobile stamping dies:

Purpose:

Automobile stamping dies are used to cut and shape flat sheets of metal (usually steel or aluminum) into specific forms and profiles required for automotive components.
Types of Dies:

Progressive Dies: These are complex dies used to create parts with multiple features and operations. As the metal strip moves through the die, it undergoes various stages, including cutting, bending, and forming, resulting in a finished part.
Transfer Dies: Transfer dies are used when a part requires multiple stamping operations, but instead of progressing along a single strip, the part is transferred from one station to another using mechanical or hydraulic mechanisms.
Single-Station Dies: These dies are used for simple stamping operations, where a single operation, such as cutting or forming, is performed at a single station.
