Abstract
With the rapid development of the national economy, the market demand for mold growth. It has been growing recognition that product quality, cost and ability to develop new products, the importance of mold in the entire chain of one of the most basic elements, mold manufacturing technology has become the measure of a country's level of importance of the manufacturing sector signs. The hopper side NE200 combination punch cutting die design, stamping process of the parts analysis of the stamping process to determine a reasonable program, design stamping process, the correct selection of standard parts, two-dimensional drawings using AutoCAD software diagram drawing tool assembly and parts diagram, the structure of the stamping process analysis. Specific part of a detailed calculation and checking. Taking into account the stamping process less demanding, but also the production of small batches, Die single process. NE200 hopper through the feed side under the combination of punching die design, consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent.
