Plate notching mechanism for drawing die

Abstract

The invention discloses a plate notching mechanism for a drawing die, which comprises a notching seat, a notching insert, a stop pin, a positioning pin and a fastening screw, wherein the notching seat is installed on an upper drawing die or a lower drawing die; the notching insert is used for notching plates in the die assembly process; a vertical stop pin hole, a vertical fastening screw installing hole and a vertical positioning pin hole are arranged at the middle part of the notching seat; the notching insert is positioned on the upper surface of the notching seat and is connected with the notching seat together; the stop pin is arranged in the stop pin hole of the notching seat; and the positioning pin and the fastening screw are respectively installed in the positioning pin hole and the fastening screw installing hole of the notching seat. In the invention, by adopting the structure by the plate notching mechanism for the drawing die and installing the structure on the upper die or the lower die of the drawing die, when the drawing process is nearly completed, waste materials are notched to enable the materials to be supplemented to the cracking regions, thereby ensuring the workpiece quality, shortening the debugging time and improving the production efficiency.

Description

technical field [0001] The invention relates to a plate notching mechanism for a drawing die. Background technique [0002] Some automobile body parts have complex shapes and deep depths. When the drawing die is stretched, there will usually be cracks in the middle of the part. It is difficult to eliminate the cracks through debugging. The reason is that during the stretching process in the middle of the part, the material at the crack Not getting refills. The part is stretched, there are waste materials supplemented by the process, including punching large holes, or waste materials at the merged place. Consider destroying the waste materials in the middle, so that the materials in the waste area can be supplemented to the cracked area on the part, so that it will no longer crack ; To destroy the waste in the middle, it is often impossible to make a damaged cut or punch on the flat material in advance, because there is a gap in advance, and another quality defect will be ea...

[0002] Some automobile body parts have complex shapes and deep depths. When the drawing die is stretched, there will usually be cracks in the middle of the part. It is difficult to eliminate the cracks through debugging. The reason is that during the stretching process in the middle of the part, the material at the crack Can't get supplement

The part is stretched, there are waste materials supplemented by the process, including punching large holes, or waste materials at the merged place. Consider destroying the waste materials in the middle, so that the materials in the waste area can be supplemented to the cracked area on the part, so that it will no longer crack ; Destroy the waste in the middle, often cannot make a damaged cut or punch on the flat material in advance, because there is a gap in advance, another quality defect will easily form during the stretching process: wrinkling

At present, there is no such plate cutting mechanism for drawing dies, which can ensure the quality of the parts, reduce debugging time, and improve production efficiency
