钢筋冷挤压连接机安全操作 | 2012-6-10 7:44:00

(1)有下列情况之一时,应对挤压机的挤压力进行标定: 

a.新挤压设备使用前; 

b.旧挤压设备大修后; 

c.油压表受损或强烈振动后; 

d.套筒压痕异常且查不出其他原因时; 

e.挤压设备使用超过一年; 

f.挤压的接头数超过5000个。 

(2) 设备使用前后的拆装过程中,超高压油管两端的接头及压接钳、换向阀的进出油接头,应保持清洁,并应及时用专用方法帽封好。超高压油管的弯曲半径不得小于250mm,扣压接头处不得扭转,且不得有死弯。 

(3) 挤压机液压系统的高压胶管不得荷重拖拉、弯折和受到尖利物体刻划。 

(4) 压模、套管与钢筋应相互配套使用,压模上应有相对应的连接钢筋规格标记。 

(5) 挤压前准备工作: 

a.钢筋端头的锈、泥砂、油污等杂物应清理干净; 

b.钢筋与套筒应先进行试套,当钢筋有马蹄、弯折或纵肋尺寸过大时,应预先进行矫正或用砂轮打磨;不同直径钢筋的套筒不得串用; 

c.钢筋端部应划出定位标记与检查标记,定位标记与钢筋端头的距离应为套筒长度一半,检查标记与定位标记的距离宜为20mm; 

d.检查挤压设备情况,应进行试压,符合要求后方可作业。 

(6) 挤压操作应符合下列要求: 

a.钢筋挤压连接宜先在地面上挤压一端套筒,在施工作业区插入待接钢筋后再挤压另一端套筒。 

b.压接钳就位时,应对准套筒压痕位置的标记,并应与钢筋轴线保持垂直; 

c.挤压顺序宜从套筒中部开始,并逐渐向端部挤压; 

d.挤压作业人员不得随意改变挤压力、压接道数或挤压顺序。 

(7) 作业后应收拾好成品、套筒和压模,清理场地,切断电源,锁好开关箱,最后装挤压机和挤压钳放到指定地点。
