في عملية تصميم وإنتاج السيارات ختم 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 ختم Die Automobile Stamping Dies

• السعر 

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

• جودة

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

• أنسنة

في عملية تصميم قالب ختم السيارات ، يعد إضفاء الطابع الإنساني أيضًا عاملاً مهمًا يجب مراعاته ، ويجب الانتباه إلى صيانته وإصلاحه بحيث يمكن عكس الاستبدال الجزئي للقالب بقوة أكبر. بالنسبة لتلك الأجزاء ذات التردد الاستبدال المرتفع نسبيًا ، يجب وضع معايير أعلى في عملية التصميم ، وهو أمر مفيد للغاية لكل من نهايتي التوريد والشراء.

• مواد أولية

عادة سبائك الصلب أو سبائك الحديد الزهر.

• صحة

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. ختم السيارات صيانة وإصلاح القوالب

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.

• تقطيع الحواف Automobile Stamping Dies

هذه واحدة من أكثر المشاكل شيوعًا التي تحدث أثناء استخدام القوالب. إذا كان تقطيع حافة السكين صغيرًا جدًا ، فمن الضروري عادةً طحن حافة التقطيع بشكل أكبر باستخدام مطحنة ولحامها بقضيب اللحام المقابل للتأكد من أن اللحام ثابت وليس من السهل تقطيعه مرة أخرى.

• تفريش

تحدث بشكل رئيسي في عمليات مثل الرسم والتشكيل والتشفيه. لمقارنة قطعة العمل للعثور على موضع التخشين المقابل للقالب ، ادفعها بسلاسة بحجر الزيت ، وانتبه إلى الحجم الموحد للزوايا الدائرية ، ثم صقلها بورق صنفرة ناعم.

• شريط تقليم وتخريم 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.

• النفايات المستمرة

نظرًا لأن المشغل لم يقم بتنظيف النفايات في الوقت المناسب أثناء عملية الإنتاج ، فقد تسبب في تراكم النفايات ، وفي النهاية ، تم كسر سكين النفايات تحت ضغط كتلة سكين التشذيب العلوية ، مما أدى إلى قطع مستمر للنفايات. تشبه طريقة إصلاحه طريقة تقليم الحواف وتقطيعها.

• خلل

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.

• نفايات اللكم المسدودة

يتم حظر نفايات التثقيب بسبب مسار النفايات غير السلس ، والانحراف العكسي لمسار النفايات ، وعدم تنظيف النفايات في الوقت المناسب. للتأكد من أن كلا الجانبين A و B في حالة سلسة ومتساوية القطر ، من الممكن التأكد من أن النفايات لن يتم سدها.

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.
