Description

Axial-movement-preventing device and method for single-tooth track steel Technical Field The invention belongs to the technical field of single-tooth track steel, and particularly relates to an axial-movement prevention device and method for single-tooth track steel. Background The crawler belt is the core manufacturing material of the crawler chain of engineering machinery such as an excavator, a bulldozer, a crawler crane, a paver and the like, and can be divided into single-tooth crawler belt, two-tooth crawler belt and three-tooth crawler belt according to the shape. The single-tooth track steel is mainly adapted to bulldozers, and the track tooth height is obviously higher than that of two-tooth and three-tooth track steel in order to enhance the grip of the track and improve the bearing capacity and the wear resistance. At present, track steel is generally produced by adopting a hot rolling process, the common flow is that a roughing mill cogging is matched with a finishing mill group, and rectangular blanks are gradually rolled into track steel meeting the specification through continuous rolling of a plurality of rolling mills. The single-tooth track steel has higher dimensional accuracy requirement, has obvious technical defects that only one thrust surface can be arranged due to the limit of the total width of rollers when the two roller sets are adopted for rolling in the existing production, horizontal movement is easy to occur after the upper roller and the lower roller are stressed, so that the width dimension of the track steel is unstable and out-of-tolerance occurs, meanwhile, the roller Kong Xingga grooves of the two roller sets are deeper due to the large height of the single-tooth track steel track teeth, the difference between the groove opening of the rolling groove and the groove bottom diameter is large, the rotating speed difference is obvious, the two side walls of the roller at the corresponding part of the track teeth are worn faster, further, the surface quality defects such as rubbing marks, wire drawing pressing and the like are easy to occur on the outer side of the track steel track teeth, and the yield is low. In addition, in order to reduce the surface defects, the grinding roller needs to be frequently stopped and repaired in the rolling process, and even the upper roller and the lower roller need to be replaced, so that the production cost is increased, the production efficiency is seriously influenced, and in summary, an axial movement preventing device and an axial movement preventing method for the single-tooth track steel are needed.
