### Demystifying the pressure of the punching parts drawing: Control the key elements of each successful manufacturing
In the manufacturing industry, the design of the stamping parts drawing ** is the cornerstone of the success or failure of the product.The stamping process is widely used in automotive, home appliances, aviation and other industries, while a complete and accurate drawing is the beginning of these industrial products manufacturing.So, in the design of stamping parts drawing, which key elements determine the success or failure of the design?This article will take you one by one to unveil these core elements, which can not only make the design more accurate, but also effectively reduce the errors and waste in production.
####*: The core life pulse of the design
Size accuracy is the most basic and important element in the design of stamping parts drawings.Any subtle size deviation will cause the product to be unable to assemble or even scrap directly.In the design of drawings, ** tolerance marks are particularly critical.The designer must clearly mark the allowable deviation of each size to ensure that the parts of different batches of production can be swapped and assembled.For example, the requirements for the size and accuracy of the car body are very strict because they need to be perfectly fit with other components.If the tolerance exceeds the standard, it will affect the appearance of the vehicle, and it will affect the performance of the vehicle.
#### 2, ** Material selection **: the material foundation of the design
Materials are one of the key factors that determine the performance and cost of stamping parts.The materials of stamping parts usually include various metal plates, such as cold -rolled steel plates, galvanized steel plates, aluminum plates, etc.The designer must choose the appropriate material according to the use of the product, the working environment and the situation.Improper selection of materials may lead to problems such as the lack of strength of the product **, ** easy to corrode ** or ** stamping and cracking **.For example, car fuel tanks generally use galvanized steel plates or aluminum plates with better corrosion resistance, while anti -collision beams are mostly high -strength steel.When selecting materials, designers must not only consider the physical properties of materials, but also consider their economy and processability.
#### 3. ** Craft **: Bridge of design and manufacturing
Craftsmanship refers to whether parts can be successfully produced during stamping processing.The design of the design ** directly affects the quality and production efficiency of stamping parts.During the design of stamping parts, the designer needs to fully consider the ductility of the material, the depth performance, and the bending radius to avoid problems such as cracking and wrinkles.Especially for the processing of complex parts, the design of poor craftsmanship can cause frequent stops and debugging in production, thereby increasing costs.For example, when designing U -shaped bending parts, the relationship between the curved radius and the thickness of the material must be fully considered. If the curved radius is too small, the material may cause cracks at the bending place.
#### Four, ** shape and structure **: the geometric element of design
The shape and structure of the stamping parts determine its functionality and applicability.When designing drawings, the shape should be as simple as possible to avoid excessive complicated curves or folding lines.Complex shapes not only increase the difficulty of mold design, but also cause stress concentration during stamping, increasing the risk of deformation and cracking of parts.For example, the metal shell of the mobile phone shell and laptop is usually relatively smooth and simple to facilitate stamping and ensure strength.
#### 五, ** Surface quality requirements **: Details determine success or failure
The surface quality of stamping parts is also an important indicator for measuring its quality.In the design drawings, ** surface roughness ** and surface treatment requirements must be clearly marked.For some products with high appearance requirements, such as home appliances shells, car ornaments, etc., there must be no obvious scratches, concave pits and burrs on the surface.When designing the drawing, the designer must not only consider the impact of the stamping process on the surface quality, but also reserve appropriate repair and polishing waste to ensure that the final product meets the quality requirements.
#### Case analysis: The drawing design of the car collision beam
In automobile manufacturing, the collision beam is a safe stamping part.Its design drawings must be very rigorous.首先，**尺寸精度**方面要确保其与车身其他部件的完美配合；其次，选材上防撞梁通常采用**高强度钢材**，以保证碰撞时的能量吸收能力；工艺性上，The anti -collision beam is often complicated, and the material requires good ** depth performance ** to avoid cracking during stamping molding.
#### words
In summary, each key element in the design of the stamping parts directly affects the quality, performance and cost of the final product.During the design process, the designer must comprehensively consider the elements of size accuracy, material selection, process, shape and structure, and surface quality to ensure accurate design to ensure that the product is made smoothly in actual production and meets the expected use requirements.Whether it is automobile manufacturing or home appliance production, scientific and reasonable stamping parts design is an important guarantee for high -quality products.
This is the key to the design of stamping part drawings. Every detail determines the success or failure of production!
