  • What kinds of stamping process can be divided into at present?

    2020-12-08 16:37:31
    The stamping process can be divided into separation process and forming process (including bending, drawing and forming). The separation process is to separate the stamping part and the blank along a certain contour line in the stamping process, at the same time, the quality of the separation section of the automobile stamping part must meet certain requirements; the forming process is to make the stamping blank plastic deformation under the condition of no damage, and transform it into the required finished product shape, and also meet the requirements of dimensional tolerance and other aspects.

    2020-09-01 10:55:15
    To distinguish the quality of automobile sheet metal parts, generally speaking, we can start from the packaging, weight, welding process, painting process and the matching degree when loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after delivery. They may as well distinguish from the product packaging in advance: the products produced by small factories will not print the contact information and address, while the regular manufacturers will also have steel seal, qualification and inspection label on the products in addition to the contact information and address, even if the consumers will be able to identify whether the sheet metal parts are of high quality after delivery At present, there can also be a way to protect rights.
  • Do you know the characteristics and classification of automobile sheet metal parts?

    2020-08-25 15:52:50
    The sheet metal part of automobile generally refers to the metal shell of automobile. It is usually made of steel plate. On the basis of ensuring certain strength, reducing weight as far as possible is the basic requirement for it. In addition to protecting and beautifying automobile sheet metal parts are also the main carrier of automobile bearing gas resistance. Therefore, the quality and service life of automobile sheet metal parts not only affect the appearance of automobile, but also increase the resistance of air to the automobile due to the quality and deformation, so as to reduce its economy.

  • Application of basic coating process in automobile sheet metal parts maintenance

    2020-08-11 15:48:27
    Black metal plate is easy to be exposed to the air or contaminated with harmful substances and other factors, and gradually occur oxidation and corrosion, resulting in yellow rust spots, damage to the original coating layer. Especially in the process of sheet metal work, after hammering, welding and other processing parts, the original coating protection layer is more likely to be damaged, accelerate corrosion, even if the paint film is sprayed, the paint film will quickly fall off with the base coating. At this time, it is necessary to conduct a thorough coating treatment.

    2020-08-04 15:45:07
    In the production process of auto sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-functional stamping die, only "high-speed" and "multi-functional" can not meet the production requirements, only to achieve continuous to the stamping machine and stamping die conveying plates, and the pressed sheet metal workpiece can be removed from the stamping die in a very short time and transported to the next stamping station, in order to ensure the economic benefits of the theory.
  • What are the existing methods of automobile sheet metal parts modeling?

    2020-07-28 15:42:16
    At present, there are some geometric modeling methods for Sheet Metal Parts, such as 2D geometry modeling for sheet metal parts and 3D geometry modeling for auto parts. The former includes coding method, face blending method and interactive dimension input method, and the latter includes bending transformation blending method and voxel blending method. The common disadvantage of all of these styling methods is that when the definition is wrong, it can be very cumbersome to modify and may even require re-entry.
