Description

Process for improving bulge of tire sidewall of engineering machinery and detection method Technical Field The invention relates to the field of tire production, in particular to a process for improving the bulge of a tire sidewall of an engineering machine tire and a detection method. Background As is known, the bulge phenomenon is easy to occur at the side wall part in the production process of the engineering machinery tyre, and the method for controlling the bulge problem process of the side wall of the engineering machinery tyre and checking the finished product is lacking in the same industry at present. Disclosure of Invention In order to overcome the defects of the prior art, the invention provides a process for improving the bulge of the side wall of the engineering machinery tire, which can effectively identify and control the abnormal bulge of the side wall of the engineering tire. The technical scheme includes that the process for improving the bulge of the tire side wall of the engineering machinery tire is characterized by comprising the following steps of a, butt joint of an airtight layer and an isolation rubber composite part, compacting after butt joint, b, cutting the tire side part at an angle of 55-75 degrees, c, bonding the airtight layer and the isolation rubber composite part, bonding and bonding isolation rubber sheets, a tire body, a rubber sheet on the tire body and bead ring bonding parts, d, bonding cushion rubber parts, bonding and bonding the cushion rubber parts, bonding the tire side part, the isolation rubber composite part, and the tire protection rubber, and the like, and bonding the tire side part, wherein the tire side part, and the isolation rubber composite part, and the tire side part are respectively subjected to lining rubber part, the isolation rubber composite part, and the tire side part, and the tire shaping, bonding, tire unloading, tire winding and tire vulcanizing after bonding are finished. The cutting angle of the joint part of the composite part is 20-25 degrees. The joint spacing of the cushion rubber, the airtight layer isolation rubber composite piece and the side wall part is more than 30 degrees. A detection method for improving the bulge of the tire sidewall of the engineering machinery tire is characterized by comprising the following steps of firstly using RIGELSCAN intelligent hand-held laser 3D scanners to scan actual profile curves of a cushion part joint and a tire sidewall part joint after vulcanization is finished, then respectively carrying out actual thickness scanning on the surface profile curves at 180 degrees, measuring, comparing and judging the scanned profile dimensions, finally comparing and measuring the actual scanned profile curves with a designed profile curve in CAD, identifying and recording the tire with the maximum thickness difference exceeding the technical control tolerance, and judging according to technical standards. The invention has the beneficial effects that the detection link of the sidewall thickness curve of the finished tire is added, the abnormal material distribution of the sidewall can be effectively identified and controlled, and the problem of abnormal quality of bulge at the sidewall is prevented.
