方法一:在冲床底部做隔振处理,减少冲床作业时声音从地面传开
方法二:给冲床加装一个隔音罩,把冲床隔起来,也就是把噪声源控制在一个罩子内,不让声音向四周扩散。
一般方案一是没有太大的作用了,除非冲床本来产生的噪音就不是特别大,最直接有效的办法还是加装冲床隔音罩。像下图这样:

首先要看使用的是什么样的高速冲床,好冲床噪音要小点,在封闭的环境中要使用隔音效果好的隔音箱,能有效的降低噪音,
其次要看冲床的数量多少,如果多台冲床摆放在同一车间,可能发生声音的共振现象,如果不使用隔音箱的话,速度最好不要调到一样高,这样可以减低噪音。
冲床在冲压时产生的声音很大,这不仅可能超出环保标准,还可能对工人的健康构成威胁。为了减小冲床在冲压时的声音,可以采取以下措施:
一、设备调整与维护
1.检查工作台:确保工作台平整,避免因不平整而产生的震动和噪音。在工作台下方垫上减震垫,也可以有效减少噪音。
2.检查模具:模具反弹可能导致噪音增大,因此应定期检查模具状态,及时更换损坏或不合格的模具。
3.润滑部件:确保冲床的各个部件润滑良好,避免因部件松动或润滑不良而产生的噪音。
4.调整行程:冲床行程过长可能导致压力过高,从而产生噪音。因此,应根据实际需要调整合适的行程。
5.保养维修:定期对冲床进行保养和维修,确保设备处于最佳工作状态,减少噪音产生。
二、改进设备结构
1.改进冲床结构:采用斜齿轮或人字齿轮代替正齿轮,可以基本消除摩擦噪声。
2.改变模具结构:通过改变模具结构来降低冲床冲裁力和延长冲床冲裁力的作用时间,如采用斜刃口、阶梯凸模等,从而降低冲压噪音。
三、设置隔音装置
1.安装隔音罩:为冲床装配全封闭的隔音罩,可以有效地降低噪音。隔音罩的设计应考虑到不影响设备本身使用寿命、方便工人巡查操作及设备维护等因素。
2.安装隔音房:在冲床车间内设置隔音房,墙体采用隔音材料结构,能有效阻挡噪音向外散射。
3.设置吸声装置:在冲床车间顶部悬挂吸音装置,或在墙壁上安装隔音材料,以进一步降低噪音。
四、其他措施
1.加工光滑材料:选择质量好、表面光滑的材料进行加工,可以减少材料在冲压过程中产生的噪音。
2.提高操作人员的安全意识:加强对操作人员的培训,确保他们正确、安全地操作冲床,避免因操作不当而产生的噪音。
综上所述,通过设备调整与维护、改进设备结构、设置隔音装置以及其他措施的综合应用,可以有效地减小冲床在冲压时的声音。
冲床噪音大肯定要进行噪音治理了。具体的降噪方法主要是用隔声罩进行降噪处理的,这种工程比较大,自己也弄不了啊,肯定要找专业的降噪公司来做。
