本文提出了復(fù)雜拉深件展開尺寸的計算方法。 - Usually used as fresh - retaining bag , garbage bag etc , which can be drawn piece by piece
可抽取式彩盒裝平口袋，適用于保鮮袋、垃圾袋等 - According to above two calculation method , different type drawing piece results are obtained , automobile install pull valve for example , is used by this calculation method , it is very useful to practice press production . ideal workpiece is on assemble obtained
利用上述兩種計算方法得到的不同類型的拉深結(jié)果，應(yīng)用于實際沖壓生產(chǎn)，如汽車制動閥安裝板，獲得了較理想的裝配要求。 - First calculation method : doing horizontal projection drawing on drawing piece , k value is introduced by area equation of projection drawing , k value is obtained by area equation , along outline of projection drawing to add k value , that is , outline shape of blank drawing , principle area - equal and shape similar are used . second calculation method : along outline of drawing piece horizontal projection drawing , to do normal line of penetration line for wantonly point of this point , to obtain high of drawing piece on this point normal line , point and point is to form outline shape of blank
計算方法之一為k值法：作拉深件水平投影圖，在該投影圖面積方程中引入k值，利用面積相等原理解方程，求得k值，沿水平投影外沿加上k值，即為毛坯圖的外廓形狀。計算方法之二為拉深線法：沿拉深件水平投影圖外廓，在任意點作該點切線的法線，在該法線上以該點拉深件的高度為量，在法線上取截點。 - Drawing piece unfold size is one basic condition under the calculation on coefficient , number of drawing , handbooks or books of press are not given , practice press production , die designer designs drawing die by experience calculation , after testing , according to deformation , state , defect shape of testing blank , shape and unfold size is revising , finally , unfold size and shape of blank are determined , designing period is longer , cost of die and work piece is to raise , economic benefit is to reduce
拉深件展開尺寸是拉深可行性分析中計算拉深系數(shù)與拉深次數(shù)的前提條件，現(xiàn)有沖壓手冊或教材對于復(fù)雜拉深件的展開尺寸計算尚未論述。復(fù)雜拉深件的沖壓生產(chǎn)中，模具設(shè)計者憑經(jīng)驗估計拉深可行性，設(shè)計制造拉深模進行反復(fù)試壓，根據(jù)試壓件的形變狀態(tài)，缺陷形貌，制定坯料展開尺寸和形狀，周期較長，因而生產(chǎn)成本高，經(jīng)濟效益不佳。 - It's difficult to find draw piece in a sentence. 用draw piece造句挺難的
- In the first part , the subject of “ stock - value of yun tianhua ” is raised in order to act as a kind of “ throwing out a brick for drawing pieces of jade . ” in the second part , the theoretical bases of the thesis are described briefly , including the theory on the value & price of stock and investment analysis and systematic trading
第一部分是拋磚引玉提出證券投資價值問題。第二部分首先分析了證券價值和證券價格的相關(guān)理論及相互關(guān)系,然后,從證券分析和證券交易的角度簡述論文依據(jù)的證券投資理論:證券分析層面的基本分析方法和證券交易層面的系統(tǒng)交易方法。
