Abstract
The utility model discloses a retreating device of a seamless steel pipe rolling machine. The retreating device comprises a machine base and a cart sliding rail arranged on the machine base. A rolled pipe core bar cart is arranged on the cart sliding rail. A portal frame is connected to the rolled pipe core bar cart. Oil cylinder bases are arranged on the positions, on two sides of the cart sliding rail, of the machine base respectively and are provided with hydraulic oil cylinders connected with a hydraulic station, and driving ends of the hydraulic oil cylinders are connected with the two sides of the portal frame. Being driven by the two hydraulic oil cylinders, the retreating device of the seamless steel pipe rolling machine is stable and reliable in operation, reduces fault rate, improves production efficiency and retreating precision and guarantees rolling quality.
Description
Technical field
The utility model relates to a kind of seamless steel tube rolling mill, relates in particular to a kind of seamless steel tube rolling mill backspace mechanism.
Background technology
In process of production, pipe mill backspace mechanism, fixing and mobile device as tube rolling mandrel trolley, when limit rolling, limit rollback, existing design is to carry out rollback by large tooth bar, because rolling exists mechanical oscillation, large tooth bar is easy to wear and easily jump tooth, has that fault rate is high, the low shortcoming that affects product quality of rollback precision.
Utility model content
The purpose of this utility model is to provide a kind of seamless steel tube rolling mill backspace mechanism, and it has failure rate is low and the high feature of rollback precision, to solve the problems referred to above that in prior art, seamless steel tube rolling mill backspace mechanism exists.
For reaching this object, the utility model by the following technical solutions:
A kind of seamless steel tube rolling mill backspace mechanism, it comprises support and is arranged at the dolly slide rail on support, on described dolly slide rail, be provided with tube rolling mandrel trolley, wherein, described tube rolling mandrel trolley is connected with portal frame, on described support, in the both sides of dolly slide rail, be provided with oil cylinder pedestal, the hydraulic jack that connects Hydraulic Station is installed on described oil cylinder pedestal, the drive end of described hydraulic jack connects the both sides of described portal frame.
Especially, the drive end of described hydraulic jack is connected with cylinder connector, and described cylinder connector is articulated with on portal frame by Connection Block.
Especially, the top of described tube rolling mandrel trolley is provided with connecting plate, by connecting plate, tube rolling mandrel trolley is connected with portal frame.
The beneficial effects of the utility model are, compared with prior art described seamless steel tube rolling mill backspace mechanism adopts two cover hydraulic jacks to drive, and not only stable and reliable operation, has reduced fault rate, and improved production operational availability and rollback precision, guaranteed rolling quality.
