A circular tube billet double ejector rod positioning device

Abstract

The invention provides a double ejector rod type positioning device for circular pipe billets. The double ejector rod type positioning device comprises a base, buffer seats, springs, ejector rods, ejector rod sleeves, collision heads, a baffle plate and bolts; the large heads of the two T-shaped ejector rods are inward and are arranged in ejector rod holes of the buffer seats in a sliding mode respectively; the springs which are arranged at the bottoms of the ejector rod holes are pressed to abut against the bottom walls through spring grooves; the thin diameter portions of the two T-shaped ejector rods are arranged in the ejector rod sleeves in a sliding mode; the thin ends of the ejector rod sleeves abut against the large heads of the ejector rods; the outer turning edges of the thick ends of the ejector rod sleeves are fixed at the opened ends of the buffer seats through the locking bolts; the two protruding collision heads are connected into connecting holes of the small heads of the ejector rods through threads respectively; two bilateral sides of the rectangular baffle plate are fixed outside the two collision heads through the connecting bolts respectively; the buffer seats are fixed on the base through the fixing bolts. According to the double ejector rod type positioning device for the circular pipe billets, the impact force on the baffle plate of the circular pipe billets can be absorbed and eased and accordingly the two circular pipe billets can be aligned and positioned accurately in the double roller channel conveying process, the working efficiency is improved, the maintenance cost is reduced, and the device and personal safety is ensured.

Description

technical field [0001] The invention belongs to the field of steel rolling equipment, and in particular relates to a double-ejector positioning device used before and after flame cutting of a seamless pipe round billet. Background technique [0002] In the production of seamless steel pipes, it is necessary to cut long continuous casting round billets to length. The flame cutting machine is an important equipment in the material preparation process. Originally, before and after the four-bar torch of the flame cutting machine is used for flame cutting, there are baffles made of steel plates at both ends of the double roller table. Relying on the forward and reverse of the double roller table, the two round pipes to be cut and cut The billet is transported to the baffles set at both ends in forward and reverse directions, and the ends of the round tube billet are aligned and positioned for buffering by using the baffles. Due to the long length and high mass of the round tube...
