Description
Technical Field
The utility model relates to a punch technical field, concretely relates to top cooling system of seamless steel pipe punch.
Background
The hot-rolled seamless steel pipe is rolled by a piercer, and the basic process of piercing and rolling comprises the following steps: the roller, guide plate and top head are formed into a closed hole pattern, and the high-temperature metal can be continuously deformed in the region formed by said hole pattern, and finally the hollow pipe blank can be rolled out from the solid pipe blank. The roller and the guide plate are relatively fixedly installed according to the technological requirements, the ejector head is installed on the ejector rod of the ejector rod trolley, and the rolling position and the post-working position are periodically alternated along with the action requirement of the rolling period. As the solid tube blank is punched into the hollow tube blank, the metal deformation is mainly concentrated on the top head; meanwhile, the ejector head works at high temperature and high pressure, so that the ejector head is easy to wear or the nose part is pressed and piled, the ejector head cannot be used for a long time, and the ejector head is frequently replaced. Water cooling of the plug during operation is required.
