五金家具螺絲與普通螺絲的強度對比
- 2019-03-08 -

  高強度螺栓和普通螺栓之間的區別在于機械性能(如硬度和抗拉強度)的差異。對于一般緊固件,對于8.8以上的蝸牛,它被稱為高強度螺栓。低于8.8的螺絲稱為普通螺絲。螺栓。


五金家具螺絲高強度螺栓


  高強度螺栓與普通螺栓不同。高強度材料45#鋼——合金鋼(如20MnTiB—— 35VB)或其他優質材料經過熱處理以提高強度,而普通螺栓主要是普通碳素結構鋼。制造無需熱處理。


  從強度水平來看:高強度螺栓通常用于8.8S和10.9S強度等級。普通螺栓一般有4.4級—— 4.8級—— 5.6級—— 8.8級。


  根據力的特性:高強度螺栓施加預緊力,外力通過摩擦力傳遞。普通螺栓通過螺栓的剪切力和孔壁的軸承壓力傳遞剪切力。


  表面處理:高強度是表面氧化變黑,黑色,普通螺栓表面不處理。


  連接差異:普通螺栓連接依賴于螺栓的剪切阻力和孔壁壓力來傳遞剪切力。當普通螺栓擰緊螺母時,預緊力很小,影響可以忽略不計。高強度螺栓連接通過施加的預張力和產生的摩擦力傳遞外力。除了高材料強度之外,高強度螺栓還在螺栓上施加大的預張力,在連接構件之間產生壓縮力,從而存在垂直于螺釘方向的大摩擦力。


  簡單地說:普通螺栓連接類似于鉚釘銷的連接,螺栓不受基本預緊力的影響。高強度螺栓連接通過預緊力按壓結構件,螺栓桿不受剪切力,并通過摩擦力傳遞,類似于焊接,因此高強度螺栓連接在鋼結構稱為螺栓焊接。
