To the question of creation of the working stand cold rolling mill pipe with safety device
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 2
Abstract
This paper presents version of the new design of the safety devices for the mill of the cold rolling pipe rational design. Considered Constructive differences safety devices and the push mechanisms of working mills of cold rolling tube constructions of “EZTM” and NPF “Vostok-Plus”. Presents the elastic characteristics of the elements of the working mill HPT - 55 for different values of the rolling force. The results showed that the most ductile element of working stand, which transmits the load from the pass to the frame, is the safety device. In order to reduce the total deformation of elements working stand and save time when replacement the element of shear, a new safety device, which is fundamentally different from the previous one, had been designed. It is set in a working mill drive line and represents a cassette with the finger of shear, at the destruction of which we need only hold its replacement without disassembling the stand. The paper also presents fragments of the technical documentation and three-dimensional models of the working stand.
