V procesu návrhu a výroby automobilu lisování 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 Lisování Die Automobile Stamping Dies

• Cena 

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

• Kvalitní

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

• Humanizace

V procesu konstrukce lisovnice pro automobily je důležitým faktorem také humanizace, která by měla být zvážena a pozornost by měla být věnována její údržbě a opravám, aby se částečná vyměnitelnost lisovnice mohla výrazněji projevit. U dílů s relativně vysokou frekvencí výměny by měly být v procesu navrhování nastaveny vyšší standardy, což je mimořádně výhodné jak pro dodávky, tak pro nákup.

• Suroviny

Obvykle legovaná ocel nebo legovaná litina.

• Přesnost

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. Údržba a opravy automobilových lisovacích nástrojů

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.

• Sekání hran Automobile Stamping Dies

Jedná se o jeden z nejčastějších problémů, které se při používání forem vyskytují. Pokud je odštípnutí ostří nože velmi malé, je většinou nutné třísku ostří větší obrousit bruskou a svařit odpovídajícím svařovacím drátem, aby byl svar pevný a nebylo snadné znovu třískat.

• Kartáčování

Vyskytuje se hlavně v procesech, jako je tažení, tváření a obrubování. Chcete-li porovnat obrobek, abyste našli odpovídající zdrsňovací polohu formy, hladce jej zatlačte olejovým kamenem, dbejte na jednotnou velikost zaoblených rohů a poté jej vyleštěte jemným brusným papírem.

• Ořezávací a děrovací páska 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.

• Nepřetržitý odpad

Protože obsluha během výrobního procesu odpad včas neuklidila, došlo k hromadění odpadu a nakonec k rozbití odpadového nože pod tlakem horního bloku ořezových nožů, což mělo za následek nepřetržité řezání odpadu. Způsob jeho opravy je podobný jako u ořezávání hran a sekání.

• Závada

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.

• Ucpaný odpad z děrování

Odpad z děrování je zablokován kvůli nehladké dráze odpadu, obrácenému zkosení cesty odpadu a včasnému čištění odpadu. Aby bylo zajištěno, že obě strany A i B budou v hladkém stavu se stejným průměrem, je možné zajistit, že nedojde k ucpání odpadu.

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.
