Description
Technical field
The present invention relates to a kind of equipment of hot rolling of seamless steel pipe, particularly a kind of driving device for mandrel trolley of seamless steel pipe oblique milling.
Background technology
At present, when rolling seamless steel pipe, be that plug is penetrated hollow billet, send in the milling train again and be rolled.Rolling mode mainly is divided into complete floating mode and restraint mode according to plug operation form; According to wear bar form have online wear the rod and line wear rod outward.The main feature of complete floating mode is that plug floats, with hollow forging enters milling train outlet platform, the circulation of taking off plugs such as rod, cooling more together; The main feature of restraint mode is the plug restraint, does not enter pipe mill outlet platform together with hollow forging, return back to raw bits behind rolling the finishing, and a plug uses repeatedly.Online main feature of wearing rod is that hollow billet directly is put into roll line, wears rod, rolling again; The main feature that line is worn rod outward is in advance plug to be penetrated hollow billet outside roll line, and it is rolling together to move into roll line again.Adopt plug onlinely to wear rod, the kind of drive of mandrel trolley mainly was divided into rack-and-pinion transmission and sprocket wheel chain drive when restraint was rolling; But all there are some problems in these two kinds of kinds of drive, rack-and-pinion kind of drive speed of service height, location accurately, but equipment investment is big, maintenance requirement is tight, maintenance cost is big; The equipment investment of sprocket wheel chain transmission mode is less relatively, but the speed of service is low, equipment failure rate is high, spare unit cost height.
Summary of the invention
The present invention has overcome that two kinds of kinds of drive of existing mandrel trolley exist or big expense height of equipment investment or the low high defective of equipment failure rate of the speed of service, and a kind of driving device for mandrel trolley that utilizes the steel wire rope transmission is provided.
The present invention is achieved by the following technical programs:
A kind of driving device for mandrel trolley, comprise frame 1, the pair of guide rails 14 that on frame 1, is provided with, the movable mandrel trolley 10 that is provided with on guide rail 14, cable drum that is provided with at the left end of frame 1 and drive unit thereof and the right-hand member of frame 1 be provided with by running block 19, below described mandrel trolley 10, be set with pulley yoke 11, on this pulley yoke 11, be respectively arranged with and advance pulley 12 and retreat pulley 13, cable drum 2 in described cable drum and drive unit thereof, by running block 19 with advance and be provided with the steel wire rope 8 that advances between the pulley 12, the drive unit of cable drum drives cable drum is just changeing the steel wire rope 8 that advances that drives on the cable drum successively by being rotated by the running block 19 and the pulley 12 that advances, thereby drive mandrel trolley 10 along rack rail 14 high-speed motion from left to right, cable drum 2 in described cable drum and drive unit thereof and retreat to be provided with between the pulley 13 and retreat steel wire rope 9, the drive unit of cable drum drives the steel wire rope 9 that retreats that the cable drum counter-rotating drives on the cable drum and rotates by retreating pulley 13, thereby drives mandrel trolley 10 along rack rail 14 high-speed motion from right to left; Between two guide rails of rack rail 14, be provided with movable V-arrangement backing roll 15, on this V-arrangement backing roll 15, be movably set with plug 16, one end and the mandrel trolley extension bar 17 of plug 16 link together by connector 18, and the other end activity of plug 16 penetrates in the hollow billet 20.
The described connector 18 that an end and the mandrel trolley extension bar 17 of plug 16 are linked together is flanges, and this connected mode is applicable to the online bar mode of wearing under the restraint mode.
The described connector 18 that an end and the mandrel trolley extension bar 17 of plug 16 are linked together is claw joints, and this connected mode is applicable to that the line under the restraint mode wears bar mode outward.
The drive unit of described cable drum comprises: the spool 3 of cable drum, an end of this spool 3 is mechanically coupled together with the output shaft of drive motors 7 by first shaft joint 4, reduction box 5 and second shaft joint 6.
The invention has the beneficial effects as follows under the lower prerequisite of equipment investment and reduced equipment failure rate, reduced the spare unit cost, maintain easily, efficiently solve the low problem of operating rate in the production process; Cooperate with supporting stopper mechanism, realized wearing rod, restraint and high speed rollback function when rolling, improved production efficiency, saved investment.
