    What are the causes and prevention methods of metal stamping parts cracking?
    沖壓件廠家為大家介紹五金沖壓件開裂的原因與預防方法有哪些?

    First, the reason for the cracking of metal stamping parts:
    一、五金沖壓件開裂原因:

    1, the local tensile stress is too large in the process of processing, due to the local tensile stress is too large, metal stamping parts will be affected by internal stress and external impact, resulting in local expansion deformation and cracking.
    1、局部拉應力過大在加工過程中,由于局部拉應力過大,五金沖壓件會受到內應力和外部沖擊的影響,導致局部脹形變形和開裂。

    2, the forming process parameters are not in place in the part forming process, the requirements of the die, the core and the parts of the two must be closely fitted together, when the machine tool slider slides down, the plastic deformation of the metal plate is pressed to achieve forming.
    2、成型工藝參數不到位在零件成形過程中,要求凹模、壓芯和兩者的零件必 須緊密貼合在一起,當機床滑塊下滑時,壓制五金板的塑性變形,實現成形。

    At this stage, the processing technicians failed to adjust the pressure of the machine in time according to the specified process requirements, resulting in unstable work and cracking of the stamping parts.
    加工技術人員在此階段未能按照規定的工藝要求及時調整機床壓力,導致工作不穩定和沖壓件開裂。

    3, flanging mold design defects This mold is common for a mold with a double cavity and a left/right part.
    3、翻邊成形模具設計缺陷該模具對于具有雙型腔和左/右部件的一個模具是常見的。

    Because the process has both flanging and forming content, and the parts are special complex, the bending surface is narrow, and the molding requires the concave mold core to be consistent with the forming surface, the mold structure has a large molding stroke, a small pressing area, and a cracking phenomenon.
    由于該工藝既有翻邊又有成型內容,且零件特殊復雜,彎曲面窄,成型要求凹形模芯與成型面一致,模具結構成型行程大,壓制面積小,有開裂現象。

    Second, metal stamping parts crack prevention method:
    二、五金沖壓件防裂方法:

    1. The drawing process of metal stamping parts: the drawing direction should make the contact area between the punch and the blank as large as possible, the reasonable shape and holding force of the surface of the holder ring should make the resistance of all parts of the holder ring surface uniform and moderate, reduce the depth of drawing, open process holes and process notches.
    1、五金沖壓件的拉深工藝:拉深方向應使沖頭與坯料的接觸面積盡可能大,壓邊圈表面的合理形狀和壓邊力應使壓邊圈表面各部分的阻力均勻適中,減少拉深深度,開工藝孔和工藝切口等。

    2, the structural design of metal stamping parts: in the design process, the radius of each rounded corner should be larger, the actual depth of the surface shape in the direction of tension should be shallow, the depth should be uniform everywhere, the shape should be as simple as possible, and the change should be as gentle as possible.
    2、五金沖壓件的結構設計:在設計過程中,每個圓角的半徑應較大,曲面形狀在拉伸方向上的實際深度應較淺,深度應處處均勻,形狀應盡可能簡單,變化應盡可能平緩。

    3, the mold design of metal stamping parts: can take reasonable design of drawing steel, increase the mold corners, reasonable design of punch and die clearance measures.
    3、五金沖壓件的模具設計:可采取合理設計拉延筋、加大模具圓角、合理設計凸模和凹模間隙等措施。

    In the processing of metal stamping parts, there will be many failures such as cracking, and it is necessary for processing plant employees to carry out reasonable design and careful operation to prevent and reduce the occurrence of bad metal stamping parts and improve product quality.
    在五金沖壓件的加工過程中,會出現開裂等許多故障,需要加工廠員工進行合理的設計和精心的操作,以防止和減少五金沖壓件不良現象的發生,提高產品質量。

    The above is the stamping parts processing manufacturers introduced to you about "What are the causes and prevention methods of metal stamping parts cracking?"
    以上就是沖壓件加工廠家為大家介紹的關于“五金沖壓件開裂的原因與預防方法有哪些?”
