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 on the original equipment will no longer be suitable for the integrated equipment and needs to be redesigned

Abstract

The invention relates to a multifunctional rolling machine with roll profiles with a punching-rolling integrating function. According to the multifunctional rolling machine, the functions of a puncher and the functions of a tube rolling machine are achieved at the same time, and the roll profiles are suitable for hole punching work or tube rolling work. The multifunctional rolling machine comprises a foreground device, a main machine and a background device, wherein the foreground device, the main machine and the background device are sequentially arranged. The background device comprises an ejector rod cart, an ejector rod cart driving device, a background support, a movement limiting and a thrust device. The ejector rod cart is arranged on the background support in a slidable manner through the ejector rod cart driving device. The movement limiting and the thrust device are arranged on the background support. The foreground device comprises receiving troughs, a foreground support and a pushing cart driving device. A pushing cart is arranged on the foreground support in a slidable manner. The main machine is arranged between the foreground support and the background support and internally provided with rollers. Each roller comprises a roller main shaft rotationally arranged on the main machine and the roll profile with the punching-rolling integrating function, the roll profiles with the punching-rolling integrating function are fixedly arranged on the roller main shafts, the roller main shafts are connected with main transmitting shafts, and the main transmitting shafts are connected with output shafts of main transmitting systems.

Description

technical field [0001] The invention relates to a seamless steel pipe production equipment, in particular to a multi-functional rolling mill with a roll-shaped integrated function of piercing and rolling. Background technique [0002] In the field of seamless steel pipe production, the function of the cross-rolling piercing machine is to pierce the solid tube blank into a hollow capillary tube, and the function of the tube rolling mill is to finish the capillary tube into a finished seamless steel tube. These two kinds of equipment are the most basic equipment necessary for the production of seamless steel pipes. In the production of seamless steel tubes, the solid tube blank is generally pierced into a hollow capillary tube by an oblique punching machine, and then the capillary tube is refined into a finished seamless steel tube by a tube rolling mill. It is a mature production technology of seamless steel pipe production technology. Whether it is the production of high-qu...
