热芯盒射芯机制芯工
热芯盒射芯机制芯工
Core ejection mechanism of hot core box
1、工作前穿戴好劳保用品。确认制芯机内无人工作且周边人员均处于安全位置;检查电器、天然气加热系统是否正常;各种连接螺丝是否松动;砂筒、射头、风管、气管有无障碍,待各部位检查正常后,方能开机工作。
1, wear good labor insurance articles before work. Verify that the core machine is not working and the surrounding personnel are in a safe position; check the electrical and natural gas heating system are normal; all kinds of connecting screws are loose; the sand barrel, ejection head, wind pipe, and trachea have no obstacle, and the work will be opened after the inspection of each part is normal.
2、天然气加热系统应按天然气使用规定进行:首先打开通风装置,然后用长棒点火放在气喷嘴上,再放开气阀门由小到大,均匀点火。严禁先放气后点火,以防爆炸或中毒。
2, the natural gas heating system should be carried out according to the use of natural gas: first open the ventilation device, and then use the long rod ignition on the gas nozzle, and then release the gas valve from small to large, uniform ignition. It is forbidden to ignite after deflation to prevent explosion or poisoning.
3、燃气压力低于规定值时,操作者应停止加热操作,经维修人员调整压力后,方可工作。
3. When the gas pressure is lower than the prescribed value, the operator should stop the heating operation and adjust the pressure after the maintenance personnel can work.
4、必须保证射砂筒有足够的芯砂(一般不少于2/3射砂筒容积)方可射砂,严禁无砂空射。
4, we must ensure that there is enough core sand (usually not less than 2 / 3 shot sand tank volume) to shoot sand, and no sand and air shooting is strictly prohibited.
5、操作时,严禁手触芯盒,从芯盒中拿取砂芯及对射砂板孔通砂孔时必须戴好手套,以防烫伤手。从芯盒中取出的砂芯要堆放整齐,防止倒塌。
5. During operation, it is strictly prohibited to touch the core box by hand, take the sand core from the core box and wear gloves when the sand passes through the hole, so as not to scald the hands. Sand cores removed from the core box should be stacked up to prevent collapse.
6、工作中精神一定要集中,不得擅自离开机器。射芯时,风门一定关紧,否则需加挡板,以免砂子将人射伤。当危害到人或设备的安全时,应果断按下急化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机停钮,待排除故障后解除急停,同时作好事故记录
6, the spirit of work must concentrate, do not leave the machine without permission. When the core is shot, the damper must be closed, otherwise the baffle should be added to prevent the sand from injuring the human. When endangering the safety of people or equipment, the emergency stop button should be pressed decisively, and the emergency stop should be lifted after troubleshooting.
7、吹芯盒时,吹芯盒的管子不得短于0.5米,手不得伸入盒内,以防意外。
7. When blowing the core box, the tube of the core box should not be shorter than 0.5 meters, and the hand should not be put into the box to prevent accidents.
8、合理使用排毒装置,并使之保持完好状态。
8, make rational use of the detoxification device and keep it in good condition
