Abstract
The invention relates to a composite perforating machine, which comprises a feed section, a main rolling mill, a centering frame, a mandril trolley, a mandril trolley driving mechanism, a steel pipe returning mechanism and a mandril 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 mandril replacing mechanism is used for replacing a mandril for secondary perforating; and thus, secondary perforating of the steel pipe can be realized.
Description
Technical field
The present invention relates to a kind of seamless steel pipe production, relate in particular to a kind of at heavy caliber seamless steel pipe production field perforating steel pipe process equipment.
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 two and wear unit if be processed into other specification steel pipes.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 compound punch of the present invention can not only be accomplished the processing of the once perforated of seamless steel pipe, can also accomplish the secondary punch processing of steel pipe continuously.
For solving the problems of the technologies described above, the compound punch of the present invention comprises pan feeding section, main mill, centering frame group, ejector rob trolley provided, ejector rob trolley provided driving mechanism, and steel pipe loopback mechanism and push rod 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 push rod more converting mechanism replacing steel pipe secondary punch processing is used push rod, thereby behind once perforated, can realize the secondary punch processing of steel pipe.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the compound punch structural representation of the present invention.
Among the figure 1, the pan feeding section, 2, main mill, 3, centering frame group, 4, main transmission; 5 lubricating arrangements, 6, push rod changing device more, 7, the excellent dolly driving mechanism in top, 8, ejector rob trolley provided; 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 compound punch of the present invention mainly consists of pan feeding section 1, main mill 2, centering frame group 3, main transmission 4, lubricating arrangement 5, push rod more changing device 6, ejector rob trolley provided driving mechanism 7, ejector rob trolley provided 8, locking and stopper mechanism 9, steel pipe is routed up mechanism 10, steel pipe loopback roller-way 11 and steel pipe loopback crane 12.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 ejector rob trolley provided driving mechanism 7 with ejector rob trolley provided 8 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; Once perforated push rod after the use (containing the top) is routed up by the stirring hook; Secondary punch processing push rod by push rod more changing device 6 insert ejector rob trolley provided guide rail; Automatically dock with ejector rob trolley provided 8; Be urged to the operating position by ejector rob trolley provided 8 with ejector rob trolley provided driving mechanism 7; Steel pipe gets into main mill 2 through pan feeding section 1 once more, accomplishes secondary punch.
The beneficial effect of the compound punch of the present invention:
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. a compound punch comprises pan feeding section, main mill, centering frame group, ejector rob trolley provided, ejector rob trolley provided driving mechanism, it is characterized in that: also comprise
Steel pipe loopback mechanism through the finished steel pipe of main mill, is transmitted back to the pan feeding section through described steel pipe loopback mechanism and prepares processing once more;
Push rod is converting mechanism more, in order to change steel pipe secondary punch processing push rod.
2. compound punch according to claim 1 is characterized in that: described steel pipe loopback mechanism routs up mechanism, steel pipe loopback roller-way and steel pipe loopback crane by steel pipe and forms.
