同強度鋁合金藉由更大的焊合壓力使能應用於擠 製模具，因此模具的内部需能承受更大的壓力。由於模 具對應機台而有固定的高度，但在習用的模具設計方法 中，模具的各部位高度(厚度）多由經驗值獲得，但高強 度鋁合金非對稱製品擠製模具無法沿用這些經驗值。本 發明運用材料力學的公式及經驗值或模 長度不變的前提下，以求取一模具的各部位高在二具:) 最佳的設計值，使該模具有足夠的強度以適用於高強度 鋁合金之擠製製程。 门 明參考第1圖至第5圖所示，第5圖揭示本發明較 佳實施例之高強度鋁合金非對稱製品擠製模具之設計 方法流程圖。本發明高強度銘合金㈣稱製品擠製模具 之設計方法流程包含： 步驟1(S1):決定模具之總高度； 步驟2(S2):計算母模之簡支樑所需高度； 步驟3(S3):計算焊合室所需高度； 步驟4(S4): 步驟5(S5): 橋接部之高度。 計算公模之橋接部所需高度；及 決疋母模之簡支樑、焊合室及公模之 11 201204483 以上設計方法逐步說明如下： 步驟1(S1):擠製模具因應機台一般有固定之尺寸 高度，因此需先決定使用的機台與材料，以決定模具之 總高度的定值ho。例如，本發明較佳實施例中使用 800T(噸)機台，材料為7075鋁合金5吋錠，模具之總 高度的定值h0。 步驟2(S2):藉由材料力學的公式，例如τ (剪應 力）=F(受力）/Α(簡支樑截面積），算出簡支樑23所需高 度至少為hi，其中簡支樑23所需高度預估為母模20 中承受最大應力之處。 步驟3(S3):藉由經驗值或模流模擬軟體求取該焊 合室30所需高度，特別需要說明的是，高強度鋁合金 需要更大的焊合室30壓力才能焊合，因此通常需要較 高的焊合室30的高度h2以提供較大的焊合壓力。在此 的焊合室30的高度包含了第一焊合室13及第二焊合室 21的南度。 步驟4(S4):例如，藉由材料力學的公式τ (剪應 力）=F(受力)/Α(橋接部截面積）算出公模之橋接部12所 需高度至少為h3。 步驟5(S5):由模具之總高度的定值h0、簡支樑所 需高度Μ、焊合室30所需高度h2及公模之橋接部12 所需高度h3做一調整而得出模具各部最後高度的最佳 設計值。 相較於習用高強度鋁合金的非對稱製品擠製模具 12 201204483 設計不易，以往完全依經驗反覆施作及修正，The same strength aluminum alloy can be applied to the extrusion die by a larger welding pressure, so the interior of the mold needs to withstand greater pressure. Since the mold has a fixed height corresponding to the machine table, in the conventional mold design method, the height (thickness) of each part of the mold is obtained from the empirical value, but the high-strength aluminum alloy asymmetric product extrusion mold cannot follow these experience values. . The invention uses the formula of material mechanics and the empirical value or the length of the mold to be constant, in order to obtain the height of each part of a mold in two:) the optimal design value, so that the mold has sufficient strength to be suitable for high Extrusion process of strength aluminum alloy. Referring to Figures 1 through 5, Figure 5 is a flow chart showing a method of designing a high strength aluminum alloy asymmetric product extrusion die in accordance with a preferred embodiment of the present invention. The design method of the high-strength alloy of the invention (4) said that the extrusion die of the product comprises: Step 1 (S1): determining the total height of the mold; Step 2 (S2): calculating the height required for the simple beam of the master mold; Step 3 (S3) : Calculate the required height of the welding chamber; Step 4 (S4): Step 5 (S5): Height of the bridge. Calculate the required height of the bridge of the male mold; and the simple beam, welding chamber and male mold of the master mold. 201204483 The above design method is explained as follows: Step 1 (S1): The extrusion mold is generally fixed in response to the machine. The height of the size, so you must first determine the machine and materials used to determine the total height of the mold. For example, in the preferred embodiment of the invention, an 800T (ton) machine is used, the material is a 7075 aluminum alloy 5 inch ingot, and the total height of the mold is fixed at h0. Step 2 (S2): Calculate the required height of the simply supported beam 23 by at least hi by the formula of material mechanics, such as τ (shear stress) = F (force) / Α (cross-sectional area of simply supported beam), where the required height of the simply supported beam 23 is Estimated to be the maximum stress in the master mold 20. Step 3 (S3): the required height of the welding chamber 30 is obtained by an empirical value or a mold flow simulation software. In particular, the high-strength aluminum alloy requires a larger welding chamber 30 pressure to be welded, so A higher height h2 of the weld chamber 30 is typically required to provide greater weld pressure. The height of the welding chamber 30 here includes the south degrees of the first welding chamber 13 and the second welding chamber 21. Step 4 (S4): For example, the height required for the bridge portion 12 of the male mold is at least h3 by the formula τ (shear stress) = F (force) / Α (cross-sectional area of the bridge) of the material mechanics. Step 5 (S5): The final value of the total height of the mold, the required height 简 of the simply supported beam, the required height h2 of the welding chamber 30, and the required height h3 of the bridge portion 12 of the male mold are adjusted to obtain the final part of the mold. The best design value for height. Compared with the asymmetrical product extrusion die of the high-strength aluminum alloy used 12 201204483 The design is not easy, and it has been repeatedly applied and corrected according to experience.
