高速护坡模具塑性变形体积不变条件,塑性变形时,物体体积的变化与平均应力成正比,具有一个正应变及负应变,具有一个负应变和两个正应变,一个主应变为零,另两个应变之大小相等符号相反.模具冲裁是利用模具使板料产生分离的一种冲压工序,这是最基本的冲压工序,分离工序的总称,包括多种工序.高速护坡模具行业备受关注,国内外需求量也增长迅速.有利润的行业就会有竞争,所以我国模具企业为了不被淘汰都陆续实行起来了精密化、高效化管理.然而说起来容易做起来难,高速护坡模具企业管理从粗心大意到精细是一个企业持续发展必然出现的趋势,如何做到精细,并且怎样落实才是重点.高速护坡模具高精度、高效率长寿命的冲模塑料注射成型模具,可成形加工几十万件,甚至几千万件产品零件,如一副硬质合金模具,可冲压硅钢片零件(E型片、电机定转子片)上亿件,称这类模具为大批量生产用模具.而适用于多品种、少批量,或产品试制的模具有:组合冲模,快换冲模,叠层冲模或成型模具,低熔点合金成型模 具等,在现代加工业中,具有重要的经济价值,称这类模具为通用、经济模具.
The plastic deformation volume of the high-speed slope protection mold remains constant, and during plastic deformation, the change in the volume of the object is proportional to the average stress. It has one positive strain and negative strain, one negative strain and two positive strains, one main strain is zero, and the other two strains have the opposite sign of equal magnitude. Mold punching is a stamping process that uses the mold to separate the sheet metal. This is the most basic stamping process and the general term for the separation process, Including various processes, the high-speed slope protection mold industry is highly concerned, and the demand at home and abroad is also growing rapidly. There will be competition in profitable industries, so Chinese mold enterprises have gradually implemented precision and efficient management in order to avoid being eliminated. However, it is easy to say but difficult to do. The management of high-speed slope protection mold enterprises from carelessness to precision is an inevitable trend for sustainable development of enterprises. How to achieve precision, And how to implement it is the key point. High speed slope protection molds are high-precision, high-efficiency, and long-life plastic injection molding molds that can process hundreds of thousands, or even tens of millions of product parts, such as a hard alloy mold, which can punch billions of silicon steel sheet parts (E-shaped pieces, motor stator and rotor pieces). These types of molds are called mass production molds. The molds suitable for multiple varieties, small batches, or product trial production include: combination molds, quick change molds, Layered stamping or forming molds, low melting point alloy forming molds, etc., have important economic value in modern processing industry, and are referred to as universal and economical molds
