        模具熱處理變形余量怎么留?

        模具熱處理變形余量怎么留?昆山奧馬小編告訴您針對模板余量我們行規是按正常理論放余量的方法(針對厚度方向)為:長度方向的千分之三,但考慮到客戶實際情況調整為如下:
        How to reserve the deformation allowance of die heat treatment? Kunshan Aoma Xiaobian tells you that our industry regulations are based on the normal theoretical allowance method (for the thickness direction) for the template allowance: 3 ‰ of the length direction, but considering the actual situation of the customer, it is adjusted as follows:
        一、厚度為正常厚度(不是太薄也不是很厚),長寬比(長度除以寬度)也為正常數值情況下:根據長度方向的千分之二來放(0.5mm為下限)
        1、 When the thickness is normal (not too thin or too thick), and the length width ratio (length divided by width) is also normal, it is placed according to two thousandths of the length direction (0.5mm is the lower limit)
        比如:a、一塊凈尺寸為20x200x300的SKD11模板,厚度就可以按300乘以千分之二(0.6mm來放)
        For example: A. for a SKD11 template with a net size of 20x200x300, the thickness can be 300 times two thousandths (0.6mm)
        b、一塊凈尺寸為10x100x150的SKD11模板,厚度就按0.5mm的下限來放,因為如按千分之二來放相當于只有0.3mm那肯定不夠
        b. For a piece of SKD11 formwork with a net size of 10x100x150, the thickness shall be placed according to the lower limit of 0.5mm, because if it is placed according to two thousandths, it will be only 0.3mm, which is certainly not enough

        二、如果厚度特別薄或者長寬比太大,模板的熱處理余量就要另放余量了:
        2、 If the thickness is extremely thin or the length width ratio is too large, the heat treatment allowance of the formwork shall be added:
        比如:a、一塊凈尺寸為8x300x300的薄板如按理論值應該是放0.6mm,但由于模板太薄很容易變形可以適當再加個0.2mm以確保后續做的出來
        For example: a. a thin plate with a net size of 8x300x300 should be placed 0.6mm according to the theoretical value, but because the template is too thin, it is easy to deform, so it can be added 0.2mm to ensure the follow-up
        b、一塊凈尺寸為15x30x800的細長板如按理論值應該放1.6mm,但由于長寬比太大也容易變形也要適當再加些余量以確保后續做的出來
        b. A slender plate with a net size of 15x30x800 should be placed 1.6mm according to the theoretical value. However, it is easy to deform due to the large length width ratio. It is also necessary to add some allowance to ensure that it can be made later
        c、一塊凈尺寸為6x30x800的細薄長板,由于板又薄、長寬比又太大那更容易變形(這個在原材料銑磨加工時就會產生變形,再加上熱處理應力的釋放那就更多的變形了)
        c. A thin and long plate with a net size of 6x30x800 is easy to deform because the plate is thin and the length width ratio is too large (it will deform when milling raw materials, and it will deform more when heat treatment stress is released)
