Abstract
The invention relates to a perforating and extending integrated machine, which comprises a feed section, a main rolling mill, a centering frame, a mandril (mandrel bar) trolley, a mandril (mandrel bar) trolley driving mechanism, a steel pipe returning mechanism and a mandrel bar replacing mechanism, wherein the steel pipe returning mechanism can be used for returning a steel pipe which is subjected to primary perforation into the feed section; the mandrel bar replacing mechanism is used for replacing a mandrel bar for extending; and thus, the extending of the steel pipe can be realized.
Description
Technical field
The present invention relates to a kind of seamless steel pipe production, especially at the heavy caliber seamless steel pipe production field.
Background technology
At present, Chang Yong piercing mill of seamless steel tube mainly consists of: compositions such as pan feeding section, main mill, centering frame group, ejector rob trolley provided, ejector rob trolley provided driving mechanism and ejector rob trolley provided guide rail only possess filled circles pipe time processing hollow steel pipe function.Must increase in addition and build the extension unit if heighten size and the precision of steel pipe.At the large-diameter steel pipe production field, rhythm of production is not high, moves many complete equipments simultaneously, has increased cost of investment and energy resource consumption.
Summary of the invention
The present invention bores a hole and extends the processing that all-in-one can not only be accomplished the once perforated of seamless steel pipe, can also accomplish the extension processing of steel pipe continuously.
For solving the problems of the technologies described above, the present invention's extension all-in-one of boring a hole comprises pan feeding section, main mill, centering frame group, push rod (plug) dolly, push rod (plug) dolly driving mechanism, and steel pipe loopback mechanism and plug be converting mechanism more.
Described steel pipe loopback mechanism routs up mechanism, steel pipe loopback roller-way and steel pipe loopback crane by steel pipe and forms.
Steel pipe loopback mechanism can be transmitted back to the steel pipe behind the once perforated pan feeding section, and plug more converting mechanism can be changed steel pipe and extends processing and use plug, thereby the extension that behind once perforated, can realize steel pipe is continuously processed.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 extends the all-in-one machine structure sketch map for the present invention bores a hole
Among the figure 1, the pan feeding section; 2, main mill, 3, centering frame group, 4, main transmission; 5 lubricating arrangements; 6, plug changing device more, 7, top rod (plug) dolly driving mechanism, 8, push rod (plug) dolly; 9, locking and stopper mechanism; 10 steel pipes are routed up mechanism, and 11, steel pipe loopback roller-way, 12 steel pipe loopback cranes.
The specific embodiment
As shown in the figure, the present invention bores a hole and extends all-in-one and mainly consist of: pan feeding section 1, main mill 2, centering frame group 3, main transmission 4, lubricating arrangement 5, push rod (plug) more changing device 6, push rod (plug) dolly driving mechanism 7, push rod (plug) dolly 8, locking and stopper mechanism 9, steel pipe are routed up mechanism 10, steel pipe loopback roller-way 11 and steel pipe loopback crane 12 and are formed.Steel pipe is routed up mechanism 10, steel pipe loopback roller-way 11 and steel pipe loopback crane 12 and is formed steel pipe loopback mechanism.Get into main mill 2 at the filled circles pipe through pan feeding section 1 and accomplish once perforated, pan feeding section 1 can be made up of pusher.Behind the once perforated; Once perforated is return with push rod (plug) dolly driving mechanism 7 with push rod; Steel pipe is routed up from centering frame group 3; Mechanism is transported to pan feeding section 1 once more through the steel pipe loopback, simultaneously, extend plug by plug more changing device 6 insert ejector rob trolley provided guide rail; Automatically dock with push rod (plug) dolly 8; Be urged to the operating position by push rod (plug) dolly 8 and push rod (plug) dolly driving mechanism 7, steel pipe gets into main mill 2 through pan feeding section 1 once more, and the steel pipe that carries out extends processing.
The present invention bores a hole and extends the beneficial effect of all-in-one:
1, reduces equipment investment: compare with unit of the same type, can reduce investment over half;
2, optimize process route: integrate the advantage of kinds of processes, reduce the workpiece time in transit, reduce the workpiece temperature drop;
3, reduce production costs: greatly reduce tool and mould quantity, minimizing personnel configuration reduces direct processing cost;
4, realization is increasingly automated: adopt industrial secondary control.
Claims (2)
1. all-in-one is extended in a perforation, comprises pan feeding section, main mill, centering frame group, push rod (plug) dolly, push rod (plug) dolly driving mechanism, it is characterized in that: also comprise
