A free forging method for an oil drill adopting a lock tongue body

Abstract

The invention discloses a free forging method for an oil drilling and production spring bolt body. The method includes the steps of 1, preparing before forging; 2, forging, specifically, including blanking, releasing blank, splitting material and pressing with angle iron, ensuring that the step is vertical and free of inclination, patting the head to be flat to ensure the thickness and dimension, finishing tail forging to ensure the forge piece dimension, clamping one end of the tail and rolling the forging head, rotating the forge piece gradually anticlockwise by 15 degrees for each time, forging arcs in sequence, forging the upper and lower planes of each arc to be flat, reserving 5mm for the top forging during rolling, ensuring the head boss dimension, forging the head boss, heating the head to the forging temperature, preventing deformation by not heating the tail, cooling with sand dust, ensuring the covering thickness is more than 80mm; 3, correcting; and 4, cooling and releasing. The free forging method for the oil drilling and production spring bolt body solves the problems that the spring bolt body forging in the prior art is large in forging and machining allowance, incomplete in forging flow line, poor in overall quality and failed in quality improvement.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment preparation, and in particular relates to a free forging method using a lock tongue body for an oil drill. Background technique [0002] The shape of the elevator lock tongue body is as follows: figure 1 , Elevator lock tongue body forging is a new topic. Its shape is a square at one end, and a circle at the other end (the axis of the circle is perpendicular to the overall midline) with a small prong, and the middle is an eccentric asymmetrical square. The product quality requirements are high, and forging is difficult. In the past, the forging of the lock tongue body was forged as a block as a whole. The machining allowance is large, the forging streamline is incomplete, the overall quality is poor, and the quality cannot be improved. Contents of the invention [0003] The purpose of the present invention is to provide a free forging method using a lock tongue body for an oil d...
