本课题是仿形瓦级进模具设计,通过冲裁件的工艺分析,确定零件能否进行冲裁,并明确在冲裁工艺及模具设计中主要解决的问题或难点所在。仿形瓦级进模模具包含折弯的基本工艺步骤,其中起伏折弯1个工步,折边一个工步。该零件材料厚度较薄,尺寸小,呈规则形状,因此采用直排样。为了便于操作和保证零件的精度,宜采用送料机和导正销配合定距,导料板导向的定位方式。考虑零件厚度较薄,采用弹性卸料方式,为了便于操作,提高生产率,模具的定位精度要求较高,因此采用四导柱模架。凸凹模通过配合加工来满足凸凹模之间的精度要求。该模具的设计过程:先通过工艺分析确定了工件的排样图(其中包含:工艺步骤的划分,条料的定距方式,凸凹模的形状等),通过排样图确定凸凹模的尺寸,通过AUTOCAD绘制出凸凹模的工程图。

Abstract
This topic is the design of progressive die for the motor rotor core, by blanking technology analysis, determine if the part for punching, and specifically in punching technology and die design of the main problems or difficulties is located. Progressive die for the motor rotor core contains two basic punches and blanking process steps, which punches including three sequences, blanking a step. Due to the mass production of parts, so using progressive die, high production efficiency, easy operation. The part material thickness of a thin, small, round, with direct layout. For ease of operation and ensure the accuracy of parts, the use of side edge and pilot bined with distance, guiding plate oriented positioning. Consider part thickness thin, flexible discharge strategies, in order to facilitate operations, increase productivity, stamping and scrap used directly by a punch from the die hole pushed out of the way under, because the part thickness of thin, blanking clearance is very small, requiring high positioning accuracy of progressive die, so four-pillar. Punch and die bined with processing to meet the accuracy requirements between the punch and die. The die of design process: first by technology analysis determine has workpiece of row sample figure (which contains: technology steps of Division, section material of will from way, punch die of shape,), by row sample figure determine punch die of size, by AUTOCAD draws out punch die of engineering figure, then application draws out die the part of three dimensional model, in accordance with the requirements with on die the parts for Ass
