Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of composite punching die structure, and in particular to a composite punching die for forging. Background Technology
[0002] Composite punching dies are die structures that can complete multiple punching processes in a single punching operation. Due to their compact structure and precise design, they can produce high-precision holes. During the punching process, the impact and extrusion of the die on the material are minimal, thus reducing damage to the hole walls. Since multiple punching processes can be completed in a single stroke, production efficiency is greatly improved. Composite punching dies are suitable for mass production, significantly reducing production costs and improving product quality.
[0003] Composite punching dies typically consist of multiple components, including an upper die base, an upper die pad, a push rod, a punch, a punch fixing plate, a guide sleeve, a guide shaft, a lower die base, a die, and a die fixing plate. These components work together to complete multiple punching operations in a single stamping process. In existing technologies, composite punching dies collect scrap material from the scrap chute using a scrap box, requiring manual handling of the sheet metal. This type of composite punching die presents several problems: firstly, the need for manual handling of sheet metal between the upper and lower die bases makes the processing less labor-saving and less safe; secondly, the scrap material tends to accumulate in the middle of the scrap box, easily clogging the scrap chute. Utility Model Content
