Abstract
The invention discloses a mandrel supporting rack suitable for a contentious rolling unit. The mandrel supporting rack suitable for the contentious rolling unit solves the problem that an existing contentious rolling unit can not quickly deal with steel piling accidents. The mandrel supporting rack suitable for the contentious rolling unit comprises a mandrel enclosing oil cylinder, a wide-open oil cylinder, back-up rolls, revolving arms, connecting rods, a C-shaped rack body, rack connecting lugs and a base. The back-up roll I, the back-up roll II and the back-up roll III are installed on the revolving arm I, the revolving arm II and the revolving arm III respectively. The three revolving arms are installed on the C-shaped rack body in a hinged mode. The C-shaped rack body is fixedly connected with the rack connecting lugs and the base through quick-opening bolts. The mandrel enclosing oil cylinder is hinged to the revolving arm II. The wide-open oil cylinder is hinged to the revolving arm I. The revolving arm I is hinged to the revolving arm II through the connecting rod I. A stop nut is arranged at one end of the connecting rod I. The revolving arm II is hinged to the revolving arm III through the connecting rod II. When the steel piling accidents happen, the mandrel supporting rack suitable for the contentious rolling unit can push out a rolling line, thereby bringing convenience to handling rolling jamming accidents and providing space for handling the rolling jamming accidents.
Description
Technical field
The present invention relates to tandem rolling unit, be specifically related to a kind of plug frames that is applicable to tandem rolling unit.
Background technology
Existing tandem rolling unit, especially MPM tandem rolling unit, when occurring rolling card accident, can there is the accidents such as heap steel, now steel pipe and plug cannot be extracted out from milling train is inner, need artificial gas cutting or other device of using that the pipe that is placed on the generation heap steel accident on plug is cut off or peeled off with plug, to save plug.Between accident pipe under the condition of high temperature and plug, there is certain gap, if will overlap after accident pipe is cooling extremely on plug, difficulty is peeled off in increasing, so accident rescue has requirement to the time, and traditional plug frames is without large opening function, cannot exit roll line, staff cannot carry out work by fast approaching accident point, for follow-up work increases difficulty.
In order to solve traditional plug frames due to without large opening function, when there is heap steel accident, the problem that staff cannot fast processing accident, is necessary to develop the plug frames of a kind of more reasonable structure, science.
Summary of the invention
The present invention is in order to solve existing plug frames without large opening function, and workman cannot fast processing pile the problem of steel accident, and a kind of plug frames that is applicable to tandem rolling unit is provided.
The present invention is achieved by the following technical solutions:
A kind of plug frames that is applicable to tandem rolling unit, comprise and embrace core oil cylinder, open greatly oil cylinder, backing roll, revoliving arm and connecting rod, C type frame, frame engaging lug and base, backing roll I wherein, backing roll II, backing roll III is installed on respectively revoliving arm I, revoliving arm II, in revoliving arm III, three hinged being installed on C-form stand of revoliving arm, C-form stand is fixedly connected with base with frame engaging lug respectively by opening soon bolt, embrace core oil cylinder and revoliving arm II hinged, open greatly oil cylinder and revoliving arm I is hinged, hinged by connecting rod I between revoliving arm I and revoliving arm II, stop nut is established in connecting rod I one end, hinged by connecting rod II between revoliving arm II and revoliving arm III.
When occurring rolling card accident, frame of the present invention can be released roll line, and convenient processing rolled card accident and provided space for rolling card accident.Its process as follows as shown in Figure 2, before rolling not yet starts, plug passes hollow billet and enters in milling train, three backing rolls of plug frames are embraced plug and are made plug and roll line centering, in the normal operation of rolling, pipe enters mill milling, and sensor detects before tube head arrives plug frames and embraces core cylinder action, three backing rolls are synchronous little open make pipe by and embrace that pipe makes itself and roll line centering until rolling finishes to enter next root pipe rolling circulates; When occurring rolling card accident, to open greatly oil cylinder work and make backing roll I rotate to position shown in Fig. 2 around its strong point, C-form stand is released along direction as shown, and now staff can fast approaching accident point processing accident.
Three backing rolls while operating principles of the present invention as shown in Figure 2, drive link I and connecting rod II drive revoliving arm I and revoliving arm III to drive the backing roll II synchronization action of installing in backing roll I, backing roll III and revoliving arm II respectively by revoliving arm II to embrace core oil cylinder, relative position between backing roll I and backing roll II can regulate by stop nut, and the relative position between backing roll III and backing roll II can regulate by rotation connecting rod II; Finally make 3 backing rolls embrace all the time plug and pipe simultaneously; While opening greatly, accident is opened greatly cylinder rod and is regained, and makes revoliving arm I rotate to diagram dotted line position around its strong point, embraces core cylinder rod simultaneously and also regains, and backing roll III and backing roll II are opened to greatly position shown in dotted line.
Apparatus of the present invention design is ingenious, simple in structure, when there is heap steel accident, can release roll line, and convenient processing is pricked card accident and provided, and provides space for rolling card accident.
