In the cost of automobile stamping parts, the material cost is more than 60%. Therefore, the economic utilization of materials is of great significance. Layout refers to the arrangement and placement of parts on strips or plates. Unreasonable layout will cause material waste. The index to measure the layout economy is the utilization rate of materials. The utility model can reduce the waste area and the material utilization rate is high.

There are two kinds of waste: process waste and structure waste. Flanging and surplus materials are called process wastes, which are related to layout form and stamping method; structural wastes are determined by the shape and characteristics of the workpiece, and generally cannot be changed. Therefore, only by designing a reasonable layout plan and reducing process waste can the material utilization rate be improved.

Reasonable layout not only affects the economic utilization of materials, but also affects the quality of parts, the structure and life of dies, the productivity of precision stamping parts and the cost of dies and other technical and economic indicators.

Good layout can improve the utilization rate of materials, facilitate the operation of staff, improve the life of stamping die and so on.

So layout should follow these four principles: improve the utilization rate of materials, improve the operability, make the die structure simple, improve the life, and ensure the quality of the workpiece. Layout shall ensure the quality of precision stamping parts, not only consider the utilization rate of materials, regardless of the performance of stamping parts. For the blanking of bending parts, the fiber direction of the sheet should also be considered during layout.

Have we ever paid attention to some parts of the car when it brings us great convenience? As one of the important parts in the automobile, compression valve cover automobile stamping parts, its production method is certainly rarely concerned, so today we will simply introduce the production focus of the product.

Compared with other auto parts, it takes more time and energy to make the stamping parts of the compression valve cover, so it can be seen that its accuracy requirements are also relatively high, so as to improve the performance of the device. In addition to the precision, there will be some burr after the production and forming of the compression valve cover stamping parts, so it needs to be polished and corrected in the later stage.

Production is on the one hand, purchase is also on the other hand, in order to get high-quality compression valve cover automobile stamping parts, we must have a comprehensive grasp of product details. At the same time, it is necessary to compare the products of different manufacturers and try to find products with high cost performance.

In fact, the performance is mainly worth the forming limit, die sticking and shape freezing of stamping parts. The forming limit mainly refers to the large deformation degree of stamping materials in the forming process, and it is on the premise of ensuring no fracture. In many cases, we regard the forming limit as the fracture resistance of materials, that is to say, the better the fracture resistance of stamping materials is, the higher the forming limit is.

The sticking and freezing properties of the die are the ability of the material to obtain the shape of the die and the shape in the die during the stamping process. There are many factors related to them. Therefore, we should pay attention to all aspects to avoid that the material performance is affected by the impression of the concept unit as much as possible, so as to produce large shape error of the stamping parts.
