The invention relates to a pipe mill limiting frame capable of improving the inner and outer surface quality of a steel pipe through stable operation of a core rod trolley. The pipe mill limiting frame comprises a pipe mill stand, wherein the core rod trolley is slidingly arranged on the pipe mill stand; limiting oil cylinders are respectively fixed at the left and right sides of the pipe mill stand; and a slide rail is arranged on the pipe mill stand, and is fixed above the pipe mill stand. The pipe mill limiting frame further comprises a composite three-body limiting frame; the composite three-body limiting frame comprises an arched frame body; a pressing oil cylinder is arranged on the arched frame body; V-shaped locking frames are respectively arranged at the left and right sides of the arched frame body, and comprise connecting arms and pressing arms; one ends of the connecting arms are fixed at one ends of the pressing arms, and are rotationally arranged on the arched frame body; the other ends of the connecting arms are hinged with a piston rod of the pressing oil cylinder; the arched frame body is arranged on the slide rail through a slide block; the end surfaces of the pressing arms are matched with the outer side surface of the top end of the core rod trolley; and the arched frame body is also fixedly connected with the piston rods of the limiting oil cylinders.
Description
technical field [0001] The invention relates to a seamless steel pipe production equipment, in particular to a stop frame for a pipe rolling mill. Background technique [0002] The stop device is the key device of the hot-rolled seamless steel pipe production equipment - the pipe rolling unit, and is closely related to the quality of the product. The existing stop device for pipe mill mainly includes mandrel trolley, pipe mill stand, stop oil cylinder, and stop frame. The disadvantage is that the stop frame and mandrel car vibrate greatly during production, which affects the inside and outside of the product. The quality of the outer surface. [0003] In view of the above-mentioned defects, the designer, actively researches and innovates, in order to create a new-type structure stop frame for pipe rolling mills, so that it has more industrial use value. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present ...
