模具专业英语本文档1

1、摘要本文介绍的模具实例结构简单实用,使用方便可靠,首先根据工件图算工件的展开尺寸,再根据展开尺寸算该零件的压力中心,材料利用率,画排样图。根据零件的几何形状要求和尺寸的分析,采用复合模冲压,这样有利于提高生产效率,模具设计和制造也相对于简单。当所有的参数计算完后,对模具的装配方案,对主要零件的设计和装配要求技术要求都进行了分析。在设计过程中除了设计说明书外,还包括模具的装配图,非标准零件的零件图,工件的加工工艺卡片,工艺规程卡片,非标准零件的加工工艺过程卡片。关键词:复合模;冲压;设计最佳答案In this passage, a reliable and practical sample mo

This height should be increased if the stock is to be lifted over a fixed pin stop .The Channel widthshould be the width of the stock strip, plus adequate clearance to allow for variations in the width of the strip cut. Choice of the methods of applying

9、springs to stripper plates depends on the required pressure, space limitations, shape of the die, nature of the work ,and production requirements . Figure 9-12 presents a number of such methods.最佳答案StrippersThere are tow types of strippers: fixed or spring-operated.The primary function of either typ

10、e is to strip the workpiece from a cutting or noncutting punch or die.A stripper that forces a part out of a die may also be called a knockout, an inside stripper, or an ejector .

11、.剥离器(脱模机有两种类型的剥离器: 固定的和弹簧驱动的.对于这两种类型而言,它们的主要功能都是将工件从剪切或者非剪切冲头(冲栽模上剥离.促使冲栽模的一部分与其自身分离的剥离器亦叫做脱模装置,内置剥离器或者脱模器(推出器.此外,剥离器还起着固定装置,薄板,剥片和工件的作用.The stripper is usually the same width and length as the die block ,In simpler dies, the stripper may be fastened with the same screws and dowels that fasten the d

12、ie block ,and the screwheadw will be counterbored into the stripper ,In more compex tools and with sectional die blocks, the die block screws will usually be inverted , and the stripper fastener will be independent .剥离器通常与冲栽模块等长等宽.在一些构造更为简单的冲栽模中,剥离器也许会和模块共用同样的螺丝和暗榫固定,同时螺丝钉的头部将钻埋于剥离器内.对于一些较为复杂的工具和那些组

13、合式冲栽模而言,螺丝钉通常都是倒置的,而且剥离器的扣件都是独立的.The stripper thickness must be sufficient to withstand the force required to strip the strip the stock from the punch , plus whatever is required for the stock strip channel. Except for very heavy tools or large blank areas, thethickness required for screwhead counte
