High-precision seamless steel tube cold rolling equipment and machining method thereof

Abstract

The invention relates to high-precision seamless steel tube cold rolling equipment and a machining method thereof. The equipment comprises a rolling mill base, a cold rolling guide groove is formed inthe rolling mill base, guide sliding rails are arranged on the groove wall faces of the two sides of the cold rolling guide groove, a connection and partition plate is arranged in the middle of the interior of the cold rolling guide groove, operation driving motors are arranged at the groove ends of the two ends of the cold rolling guide groove, sliding rolling frames are slidably connected to the guide sliding rails, the operation driving motors are in transmission connection with driving screw rods, the driving screw rods are movably connected with the sliding rolling frames in a penetrating mode, the other ends of the driving screw rods are in lap joint with the connection and partition plate, and the two sliding rolling frames are arranged on the guide sliding rails. According to thehigh-precision seamless steel tube cold rolling equipment and the machining method thereof, cold rolling can be performed for a plurality of seamless steel tubes with different tube diameters at the same time, the cold rolling process is achieved through back-and-forth movement and self-rotation of rollers on the surfaces of tube bodies, the production mode that a rolling mill is manually operatedfor rolling is replaced, rolling of the multiple steel tubes with the different tube diameters can be completed simultaneously at a time, the rolling efficiency is high, and the surface cold rollingeffect of seamless steel tubes is good.

Description

technical field

[0001] The invention relates to the technical field of cold rolling of seamless steel pipes, in particular to a high-precision cold rolling equipment for seamless steel pipes and a processing method thereof. Background technique

[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 e...
