Hebei Xuangong Company's 12-meter-long steel tie rod was successfully developed and processed

As of August 5, Hebei Xuangong Company completed 1200 steel rods with a length of 12 meters, indicating the successful development and production of super-long drawbars.
The 12-meter-long steel rods are difficult to process. In order to ensure the processing quality and safe production, the processing plants make their own tooling, use the auxiliary support at the rear of the workpiece, use the V-shaped iron to position the head, and make positioning pins on the tooling. The holes are drilled through the pre-drilled hole and the positioning pin hole to improve the production efficiency. One class can process 40 pieces and the efficiency is increased by nearly 10 times. The heat treatment process is the key process of production. In order to ensure the processing quality, the operator continues to dry up to three or four points in the night, and four furnaces are used for quenching and tempering. In order to reduce the deformation of the workpiece, the tooling is designed and manufactured to achieve uniform heating and cooling of the workpiece. standard. The successful development of steel drawbars has opened up new ways for companies to further expand the processing market. (This article comes from propaganda)
