Problems solved by technology

For medium and low-grade seamless steel pipes, the production cost of this process is relatively high
Moreover, for enterprises that want to build seamless steel pipe production lines, they must build piercing units and pipe rolling units without exception. This is a large investment for manufacturers whose products are positioned in general industries and civilian use, and the equipment capacity is excessive.
In addition, if the functions of the piercing machine and the pipe rolling mill are integrated on one piece of equipment, the roll shape with the rotary sizing function on the original equipment will no longer be suitable for the integrated equipment and needs to be redesigned

Abstract

The present invention relates to a multifunctional rolling mill with rotary and sizing functions, which has both the functions of piercing machine and pipe rolling mill, and its roll shape is suitable for rotary sizing operation, including the foreground equipment, the main engine and the backstage which are arranged in sequence Equipment, the background equipment includes the ejector trolley, the ejector trolley driving device, the background support, the stop device and the thrust device, the ejector trolley is slidably arranged on the background support through the drive of the ejector trolley drive device, the stop device and The thrust devices are respectively arranged above the background support; the front equipment includes the receiving trough, the front support and the driving device of the pushing trolley arranged in sequence, and the pushing trolley is slidably arranged on the front support, and the host is arranged on the front support and the background support. Between them, there is a roll in the main machine, the roll includes a roll main shaft rotatably arranged on the main machine and a rotary sizing function roll type fixed on the main shaft of the roll, the main shaft of the roll is connected with the main drive shaft, and the main drive shaft is connected with the main drive system connection.

Description

technical field [0001] The invention relates to a seamless steel pipe production equipment, in particular to a multi-functional rolling mill with a rotary sizing function roll type. Background technique [0002] In the field of seamless steel pipe production, the role of the skew rolling piercer is to pierce the solid tube blank into a hollow capillary tube, and the role of the pipe rolling machine is to finish the capillary tube into a finished seamless steel tube. These two kinds of equipment are the most basic equipment indispensable for the production of seamless steel pipes. When producing seamless steel pipes, the solid tube blanks are usually pierced into hollow capillary tubes by a diagonal piercing machine, and then the capillary tubes are finished into finished seamless steel pipes by a pipe rolling machine. It is a mature production process since the development of seamless steel pipe production technology. Whether it is to produce high-quality seamless steel pip...
