The invention provides ejector rod pushing equipment for a perforating machine. The ejector rod pushing equipment comprises an jacking rod car, an ejector rod anti-thrust device and a base, wherein the ejector rod car is used for operating an ejector rod for perforation and comprises a car body, a rotatable jacking shaft and a holding device, and the holding device and the jacking shaft work together to drive the ejector rod to move; the ejector rod car is connected with the ejector rod anti-thrust device in a sliding manner; the ejector rod anti-thrust device comprises a feeding device, the feeding device is used for driving the ejector rod car and enabling the ejector rod to enter the working position before rolling and back off to be behind the working position after rolling according the rolling requirement; the base bears the ejector rod anti-thrust device and is in sliding fit with the ejector rod anti-thrust device; and the base comprises an axial adjusting device for axially positioning the ejector rod. The ejector rod pushing equipment can continually and quickly push ejector rods and accurately position the ejector rods, thereby realizing quick and repeated use of multiple ejector rods for perforation, shortening the production interval time and improving the production efficiency.
Description
technical field [0001] The invention relates to a pipe rolling machine, and in particular to a push rod pushing device of a piercing machine in the production of seamless steel pipes. Background technique [0002] In the production of seamless steel pipes, the piercer uses a ejector pin to punch a hole in the heated solid blank to form a so-called capillary tube. Thereafter, the ejector pin needs to be separated from the capillary tube, the capillary tube is transferred to the rolling mill for further rolling, and the ejector pin needs to be returned to the piercing machine for the next piercing. [0003] The current piercing process generally uses a fixed pin, and the ejector pin must be penetrated, pulled out and cooled at the same station, which not only takes up production time, affects the output of the capillary tube, but also tends to cause poor cooling of the ejector pin, which will affect the quality of the product. Contents of the invention [0004] In order to...
