Problems solved by technology

[0002] The current production of seamless steel pipes mainly includes cold rolling and hot rolling, and the rolling method of small-diameter seamless steel pipes is mainly cold rolling. However, the current rolling process and equipment of seamless steel pipes in my country are relatively backward, and the efficiency is relatively low. Especially in terms of cold rolling, the rolls of the cold rolling equipment need to be fed only once during the reciprocating movement of the rolling workpiece, and the steel pipe is rolled once, and only one steel pipe is rolled each time, that is, in one cycle of the reciprocating movement of the roll. During the cycle, the roll only works once. At present, domestic seamless steel pipe cold rolling enterprises, especially small and medium-sized enterprises, mostly adopt this kind of rolling process and equipment, which will inevitably lead to the low efficiency of the current domestic seamless steel pipe cold rolling industry. , high energy consumption and high cost

Abstract

The invention relates to a high-precision seamless steel pipe cold-rolling equipment and a processing method thereof, comprising a rolling mill base, on which a cold-rolling guide groove is arranged, and guide slide rails are arranged on the groove wall surfaces on both sides of the cold-rolling guide groove, so that The middle part of the cold-rolled guide groove is provided with a connecting partition, and the ends of the two ends of the cold-rolled guide groove are provided with running drive motors. Screw, the driving screw is connected with the sliding rolling stand, and the other end of the driving screw is overlapped with the connecting partition, and there are two sliding rolling stands on the guide rail. The present invention can cold-roll multiple seamless steel pipes with different diameters at the same time, and the cold-rolling process is realized by the rolling back and forth on the surface of the pipe body and its own rotation, replacing the production mode of manual rolling with a rolling mill, and can simultaneously Complete the rolling of multiple steel pipes with different diameters, the rolling efficiency is high, and the surface cold rolling effect of the seamless steel pipe is good.
