  • 五金冲压件模具的保养与维护

    五金冲压件模具的使用寿命与冲压件模具结构设计、冲压件模具钢材选用、热处理、表面处理、机械加工研磨、线切割工艺,冲压设备、冲压材料及工艺,冲压件模具润滑、保养维修水平差等诸多因素有关。

     

          其中引起冲压件模具失效的各种因素中,冲压件模具结构不公道、选材不当约占25%,热处理不当约占45%,工艺题目约占10%;设备题目、滑润题目等因素约占20%。金冲压件安装后要留意保养,防止生锈侵蚀.在日常使用时要轻关轻开,防止硬关硬开,造成损坏。

     

          以下为如何防止五金冲压件损坏:

        1、滑撑铰链不得采用铝合金材料,应采用不锈钢材料。
       
        2、对宽度超过1米的推拉窗,或安装双层玻璃的门窗,宜设置双滑轮,或选用动弹滑轮。

        3、五金配件金应最后安装,门窗锁、拉手等应在窗门扇入框后再组装,保证位置准确,开关灵活。

        4、用紧固螺丝安装五金件,必需内设金属衬板,衬板厚度至少应大于紧固件牙距的两倍。不得紧固在塑料型材上,也不得采用非金属内衬。

        5、用五金配件的型号、规格和机能应符合国家现行尺度和有关划定,并与选用塑钢门窗相匹配。

        6、五金冲压件安装后要留意保养,防止生锈侵蚀。在日常使用时要轻关轻开,防止硬关硬开,造成损坏。

     

  • 拉伸冲压件的使用寿命分析

    拉伸冲压件的使用寿命,除了取决于合理的模具结构,高的制造精度,良好的热处理效果以及正确地选用冲床、拉伸冲压件安装精度等因素外,模具的正确使用、保养和维护也是不可忽视的环节,对此应注意以下几点:

      (1)拉伸冲压件安装使用前应严格检查,清除脏物,检查拉伸冲压件的导向套和模具是否润滑良好。

      (2)拉伸冲压件的凸模和凹模刃口磨损时应停止使用,及时刃磨,否则会迅速扩大模具刃口的磨损程度,加速模具磨损,降低冲件质量和模具寿命。

      (3)保证拉伸冲压件的使用寿命,还应定期对模具的弹簧进行更换,防止弹簧疲劳损坏影响拉伸冲压件使用。

      拉伸冲压件是靠压力机和模具对板材、带材、管材和型材等施加外力,使之产生塑性变形或分离,从而获得所需形状和尺寸的工件(冲压件)的成形加工方法。冲压和锻造同属塑性加工(或称压力加工),合称锻压。冲压的坯料主要是热轧和冷轧的钢板和钢带。

      冲压件主要是将金属或非金属板料,借助压力机的压力,通过冲压模具冲压加工成形的,它主要有以下特点:

      (1) 冲压件是在材料消耗不大的前提下,经冲压制造出来的,其零件重量轻、刚度好,并且板料经过塑性变形后,金属内部的组织结构得到改善,使冲压件强度有所提高。

      (2)冲压件在冲压过程中,由于材料的表面不受破坏,故有较好的表面质量,外观光滑美观,这为表面喷漆、电镀、磷化及其他表面处理提供了方便条件。

      拉伸冲压件与铸件、锻件相比,具有薄、匀、轻、强的特点。冲压可制出其他方法难于制造的带有加强筋、肋、起伏或翻边的工件,以提高其刚性。由于采用精密模具,工件精度可达微米级,且重复精度高、
