Description

Technical Field

[0001] The utility model relates to a grinding wheel saw and belongs to the technical field of metallurgical equipment. Background Art

[0002] In the bar machining process, the first necessary post-finishing process of the bar rolling line is sawing. The grinding wheel saw is the most commonly used sawing equipment in the bar production line because of its wide range of applications and high sawing quality. At present, most special steel plants use grinding wheel saws on the output roller of the cooling bed to saw the bars after preliminary cooling. Several grinding wheel saws are sawed simultaneously or sequentially to improve the sawing efficiency and meet the requirements of faster rolling rhythm.

[0003] The existing grinding wheel saw swing mechanism can only swing up and down, and cannot feed forward and backward, which greatly limits the use range and production efficiency of the grinding wheel saw; in addition, the diameter of the saw blade of the grinding wheel saw is constantly reduced during the sawing process. When the size of the saw blade is smaller than a certain size, the saw blade needs to be replaced. The existing saw blade chuck structure design is unreasonable (see CN218518373U). Its main chuck and auxiliary chuck are both installed on the output shaft and fixed by a locking nut. The locking nut is fixed by a locking piece and a circular pressure plate. Since the saw blade generates a lot of heat during the production process, it is easy to cause the locking piece to deform and cannot be removed from the output shaft after long-term use. At this time, the output shaft needs to be replaced, which greatly increases the equipment maintenance cost. Utility Model Content
