Feed-in mechanism for cold-rolling pipe mill

Abstract

The invention relates to a feed-in mechanism for a cold-rolling pipe mill, and belongs to the technical field of machining machines of metal pipes. The feed-in mechanism comprises a box base and a transmission speed reduction device, wherein a box cover is arranged on the upper part of the box base; and the transmission speed reduction device is arranged on the box base and is covered by the box cover. The feed-in mechanism is characterized in that: the transmission speed reduction device comprises a power input shaft, a first speed reduction shaft, a second speed reduction shaft, a third speed reduction shaft, a first power output shaft, a second power output shaft and a reversing shaft, which are arranged on the box base sequentially and rotationally, wherein the power input shaft is intransmission connection with an external power device and is matched with the first speed reduction shaft; the first speed reduction shaft is matched with the second speed reduction shaft; the secondspeed reduction shaft is matched with the third speed reduction shaft; the third speed reduction shaft is matched with the first power output shaft; the reversing shaft is positioned between the first power output shaft and the second power output shaft and is matched with the first power output shaft and the second power output shaft; and a core rod conduit for allowing a core rod to pass through is formed on the box cover. The feed-in mechanism has a simple integral structure, is favorable for manufacturing and contributes to installation and maintenance in the future.

Description

technical field [0001] The invention belongs to the technical field of metal pipe material processing machinery, and in particular relates to a feeding mechanism of a cold rolling pipe machine. Background technique [0002] Cold-rolled pipe mills are widely used in the pipe processing industry, and there is no shortage of technical solutions related to cold-rolled pipe mills in Chinese patent documents. For example, a two-roller cold-rolled pipe mill disclosed in the utility model patent authorization announcement number CN201223884Y Rolling mill tube billet continuous feeding device, the achievements of this program have solved the technical problem that the previous two-roll cold-rolled tube mill cannot work continuously, because, when the two-roll cold-rolled tube mill in the prior art is fed Finally, since the feeding trolley can only withstand the rear end of the tube billet, the feeding trolley must be returned to the original position (reset), and the next tube blank ...
