托辊,是管子加工之一重要辅助设备。过去,国内管子车床配置的托辊都是刚性的,常见的有“U”型和“A”型两类。前者成组安装于辅机升降大梁上,一般用于管子车丝机,切管机等生产机床;后者单独安装在地面滑轨上,井矿现场修扣和小批生产多采用这种型式。由于这种托辊是刚性的,不能克服管子加工旋转时因弯曲而与托辊产生的冲击和“别劲”现象,造成辅机、管身和机床 Roller, is an important auxiliary pipe processing equipment. In the past, the domestic tube lathe roller configuration is rigid, there are common “U” type and “A” type two types. The former is installed in a group of auxiliary machine lifting girder, generally used for pipe production line machine, pipe cutting machine and other production machine; the latter installed on the ground slide alone, well mine site repair buckle and small batch production more use of this type . Because of this kind of roller is rigid, can not overcome the tube processing due to bending and bending with the roller impact and “not the best” phenomenon, resulting in auxiliary machinery, pipe and machine tools
