Buffering device for cogging mill manipulator guide point

Abstract

The invention discloses a buffering device for a cogging mill manipulator guide point. The guide point (1) is fixedly arranged on a manipulator (6) through a fixing pin (7); a thin steel plate (2) is welded on the guide point (1); a spring (3) is arranged on the guide point (1); and one end of the spring (3) is fixed on the guide point (1), and the other end of the spring (3) is fixed on the manipulator (6). According to the buffering device, the guide point is fixed thoroughly, so that friction between a guide point safety pin and a pin hole is reduced, and the guide point can be used normally; therefore, steel materials can be input into or output from a rolling slot of a cogging mill precisely; and when the guide point swings a lot and fails, a full-automatic program stops automatically, and rolling is stopped, so that equipment is protected.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to process equipment for steel rolling production. More specifically, the invention relates to a buffer device for a pusher guide tip of a blanking machine. Background technique [0002] In steel rolling production, bars of any specification are rolled by billet mills. During rolling, the precise grooving of steel in each pass depends on the precise positioning of the guide tip. However, due to repeated rolling for a long time, the fixed pin of the guide point is severely worn. The main reason is that when the guide point is positioned accurately, the guide point is subjected to the thrust of the steel, which makes the guide point swing. The swing causes two disadvantages: [0003] First, due to the long-term swing, the guide tip cannot quickly return to the same plane position as the push bed, resulting in inaccurate positioning of the guide tip; it will...

Problems solved by technology

However, due to repeated rolling for a long time, the fixed pin of the guide point is severely worn. The main reason is that when the guide point is positioned accurately, the guide point is subjected to the thrust of the steel, which makes the guide point swing. The swing causes two disadvantages:

[0003] First, due to the long-term swing, the guide tip cannot quickly return to the same plane position as the push bed, resulting in inaccurate positioning of the guide tip; it will cause steel material torsion, and even process accidents such as flat steel;

[0004] Second, the safety pin of the guide point is worn for a long time, which reduces its strength. When the wear reaches a certain level, the positioning pin breaks. Weijian's transformation is imminent
