Second line set volume separation refers to pin down

Second line set volume separation refers to pin down 2019 - 01 - Xingtai iron and steel co. , LTD. 25 second line set volume separation refers to the installed at the bottom of the nose, are connected by a connecting rod and the pin shaft, hydraulic driving connecting rod movement, which is used to support the nose, smooth flow of blanking. Stay at the end of the blanking, separation refers to the open, the nose, will import the mandrel, and then hold claw cylinder lift the nose, separation refers to the insert, mandrel spinning, prepare the next blanking. Maintenance staff had problem is that every month pin shaft fracture or loose nut, equipment accidents, affect production. Class for this purpose, the preparation workshop finishing homework according to the cause of the problems of the counter shaft fracture are analyzed, found that the main reason is that pin connected with screw is fine, the other connecting rod hole wear, lead to pin shaft rupture easily, thus affecting normal production. After analyzing the reasons, preparation workshop finishing class made immediate action, the original bolt bold, according to the size of the original pin will be close to one end of the joint bearing screw head to M36, fixed end screw head into M48; The use of waste head design nut fixed locking device. The second line set volume separation refers to the pin shaft transformation after the completion of the effect is remarkable, since revamped substations have not pin screw fracture accident has occurred, provides guarantee for the stability of the wire factory production.
