    2020-09-15 16:03:38
    There is no need to say much about the cracking of automobile stamping parts. It is obvious that necking is difficult to detect. First of all, understand the mechanism of material deformation. The process of material tensile plastic deformation is mainly composed of three stages: uniform elongation stage, local elongation stage and cracking stage. Uniform elongation stage is the ideal stage, with material length direction, uniform thinning in thickness direction and surface The quality of the material is good, smooth, and the original roughness of the material has no obvious change, which is almost invisible to the naked eye. In the local elongation stage, the material is basically close to the elongation limit, and the purpose of elongation is mainly achieved through local severe and rapid deformation.

    2020-09-08 10:17:49
    It is also one of the commonly used methods of concave shaping to pull out the concave by using a pulling device. The pulling device includes a suction cup, a pulling cylinder and a special puller. There is a suction cup at the end of the pneumatic concave puller to produce vacuum, and the force exerted by the inertia hammer will pull the metal depression back to the original shape. The screw at one end of the pull rod puller is screwed into the hole drilled in advance at the concave part. Holding the handle direction with one hand, the depression can be eliminated by pulling repeatedly, and then the through-hole is blocked with packing. In order to avoid the inconvenience caused by drilling, the pin can also be used to replace the screw in the concave spot welding, and then the tool is used to cut the solder joint after pulling out, so as to maintain the integrity of the metal surface.
