The utility model relates to the technical field of automobile parts processing, disclose a kind of stamping device for automobile parts suitable for different size processing, including device main body, the upper end outer surface of device main body is fixedly connected with U-shaped frame, the upper end outer surface of U-shaped frame is fixedly connected with cylinder, the lower end of cylinder is through the inner wall of cylinder and is fixedly connected with mounting plate, the lower end outer surface of mounting plate is detachably connected with stamping plate, buffering assembly is arranged between the mounting plate and U-shaped frame, when using the device, can over set buffering assembly, the stamping force of stamping plate can be buffered, can protect that component will not be subjected to greater impact force, the connecting plate upper end of stamping plate is slid into L-shaped mounting block by the L-shaped mounting block of setting, the bolt of rotating L-shaped mounting block side makes that limiting insert block is inserted with fixed hole, stamping plate can be installed, time is saved.

The application discloses a multi-gradient sharp corner punching die for amorphous alloy based on notch sensitivity and application thereof to punch amorphous alloy, soft magnetic material or metal thin strip. The multi-gradient sharp corner punching die for amorphous alloy based on notch sensitivity comprises a die body and a die front end; the die front end is provided with a circular punching end face; a plurality of sharp corners with top angles towards a punching direction are arranged on the edge region of the punching end face along the circumference thereof, the sharp corners are periodically arranged from high to low and then to high, and the higher the sharp corner is, the smaller the top angle is.

The present application belongs to the technical field of punch forming, and relates to a packaging aluminum pipe punch forming device. The present application comprises a packaging aluminum pipe punch forming device, which comprises a die and a punch. A die cavity that is matched with the punch is formed in the die. A bar magnet is arranged in the punch. A radially magnetized annular magnet is arranged in the die. The axis of the radially magnetized annular magnet coincides with the axis of the die cavity. When the punch is inserted into the die cavity to punch, a radial repulsive force is generated between the radially magnetized annular magnet and the bar magnet, so that the punch is kept at the central position of the die cavity. The strong repulsive force generated by the same polarity of the radially magnetized annular magnet and the bar magnet can keep the punch at the central position, so as to resist the lateral force that causes the bending of the punch, and effectively prevent the bending and deformation of the punch. Therefore, the wall thickness uniformity and straightness of the formed packaging aluminum pipe are ensured.
