technical field

The invention relates to the technical field of automobile parts processing, in particular to an insert-type automobile flanging shaping mould.

Background technique

Auto parts are the parts that make up the car. When the auto parts are flanging, they will use the flanging shaping die. By placing the material above the lower die, the upper die moves down to contact the material, and the material is pressed to the bottom. In the groove of the mold, the automobile parts of the required shape are made;

However, the upper die is generally pressed down from the middle area of the processed material. When the material is pressed, the two ends of the material will warp upward, and with the increase of the pressing range, the upward warping amplitude of the two ends of the processed material will gradually increase. When the processing material with a large pressing range is processed, the two ends of the processing material will gradually become perpendicular to the upper mold, making it inconvenient for the upper mold to press the two ends of the processing material into a horizontal shape, and the occurrence of the end of the processing material is easy to occur. The folding condition affects the processing quality of the material. For this reason, we propose an insert-type automobile flanging shaping mold.
