Description
Technical Field
The utility model relates to a workpiece end blanking and punching assembly in a stamping die.
Background
When the stamping die is used for processing a workpiece, if punching and excess material cutting operations with relatively close intervals are required to be completed on the end part of the workpiece, the workpiece is relatively close to the end part of the workpiece, deformation is relatively large during processing, the finished product is easily out of compliance in size, and workpiece tearing can occur during severe processing, so that the workpiece is generally completed by adopting two working procedures. However, this processing technology sometimes needs to add an additional stamping die to meet the processing requirement, which not only increases the die cost, but also greatly increases the processing cost.

when the upper die holder punches downwards, the punching driving piece drives the punch head on the punching guide base to finish punching firstly, and the end blanking driving piece drives the cutting-off cutter block of the blanking sliding seat to contact with the workpiece to finish cutting-off operation.
As a preferable scheme, the lower die holder is provided with a side positioning guide seat matched with the surface of one side of the cutting-off knife block, which is close to the outer side wall of the upper die holder.
As a preferable scheme, a wear-resistant block is arranged on one side surface of the cutting-off knife block, which is close to the outer side wall of the upper die holder.
As a preferable scheme, two sides of the blanking driving block are respectively provided with a limit strip; the two sides of the blanking sliding seat are respectively provided with an inverted L-shaped limit hook which is matched with the corresponding limit strip and hooks the upper edge of the limit strip after the blanking sliding seat slides; limiting strips are respectively arranged on two sides of the punching driving block; the two sides of the punching sliding seat are respectively provided with an inverted L-shaped limit hook which is matched with the corresponding limit strip and hooks the upper edge of the limit strip after the punching sliding seat slides.
The beneficial effects of the utility model are as follows:
