The invention discloses a double-core rod cooling and lubricating device for a continuous pipe rolling mill, and relates to the field of steel pipe production equipment. The double-core rod cooling and lubricating device for the continuous pipe rolling mill comprises a base; an intermediate core rod conveying device is arranged in the length direction of the base; the intermediate core rod conveying device comprises a plurality of first core rod conveying supporting rollers which are arranged in sequence; core rod cooling and lubricating systems are symmetrically arranged at the positions, on the two sides of the intermediate core rod conveying device, on the base; a Wheatstone steel moving structure is arranged between each core rod cooling and lubricating system and the intermediate core rod conveying device; the Wheatstone steel moving structures are connected to the machine seats of the core rod conveying supporting rollers. According to the double-core rod cooling and lubricating device, two core rods can be simultaneously cooled and lubricated cyclically, cooled and lubricated core rods can be provided for the pipe rolling mill uninterruptedly, the cost is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to steel pipe's production apparatus field, be specially the double-core axle cooling of a kind of tandem rolling tube machine, lubricating arrangement.
Background technology
Tandem rolling tube machine is the nucleus equipment of continuous rolling-tube unit, and in the operation of rolling, the roll of tandem rolling tube machine and plug to bear high temperature, it follows that single plug can not adapt to produce, it is therefore necessary to two plug periodic duties. Select suitable plug endless form and equipment on the product mix of production line, cost of investment, plug life-span, the quality of finished product and the productivity ratio of whole unit are had impact.
At present, the existing continuous rolling production line of China, or the continuous rolling production line of Introduced From Abroad, it is all 6 frames or 6+1 frame, long flow process continuous rolling production line, also bring the equipment cost of costliness while of asking large-duty, production line investment is very big, and the cost that tool and mould consumes is also significantly high, and operant skill requires significantly high. Current tandem rolling line is all adopt cooling and the lubrication of doing plug systemic circulation to realize plug, and device structure is complicated, and floor space is big, control, operation, maintenance complexity, and all produces by sacrifice rolling ratio when producing small-caliber steel pipe, also just brings high energy consumption. And when producing small lot boiler tube, this tandem rolling line does not have advantage to say, therefore short route continuous rolling production line would is that the developing direction that boiler tube produces.
Summary of the invention
It is an object of the invention to provide the cooling of the double-core axle of a kind of tandem rolling tube machine, lubricating arrangement, this device can simultaneously to two plug circulating coolings and lubrication, the plug provide cooling to pipe mill incessantly, having lubricated, improves production efficiency, reduces energy consumption simultaneously.
The technical scheme realizing above-mentioned purpose is: the double-core axle cooling of a kind of tandem rolling tube machine, lubricating arrangement, it is characterized in that: include pedestal, described pedestal is provided with middle plug conveyer device along its length, and middle plug conveyer device includes multiple the first plug conveying carrier roller being arranged in order; The pedestal of described middle plug conveyer device both sides is symmetrically arranged with plug cooling, lubricating system, being provided with Si Huidun between plug cooling, lubricating system and middle plug conveyer device and move steel construction, described Si Huidun steel moving mechanism is connected on the support of plug conveying carrier roller.
The cooling of described plug, lubricating system include the bosh, plug rollgang, core stick graphite lubricating system and the holder chain conveying mechanism that are arranged in order, and Si Huidun steel moving mechanism is arranged between holder chain conveying mechanism and middle plug conveyer device.
Described plug rollgang includes multiple the second plug conveying carrier roller carrying roller being arranged on pedestal by bearing block, the corresponding reductor driving the second plug conveying carrier roller to rotate of each second plug conveying carrier roller.
First plug conveying carrier roller of described middle plug conveyer device adopts liftable carrying roller.
The present invention can simultaneously to two plug circulating coolings and lubrication, the plug provide cooling to pipe mill incessantly, having lubricated, reduce cost, improve production efficiency, tool and mould consumption can also be reduced, there is low energy consumption, oligosaprobic feature, ensure that product quality, provide the thinking of the plug circulation cooling lubrication of a kind of innovation for China's rolling production seamless steel pipe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present invention includes pedestal 1, pedestal 1 is provided with middle plug conveyer device 2 along its length, and middle plug conveyer device 2 includes multiple the first plug conveying carrier roller 3 being arranged in order; Be symmetrically arranged with plug cooling on the pedestal 1 of middle plug conveyer device both sides, lubricating system 4 forms cooling, lubricate A district and cooling, lubrication B district.
Bosh 5, plug rollgang 6, core stick graphite lubricating system 7 and the holder chain conveying mechanism 8 that plug cooling, 4 systems that lubricate include being arranged in order, being respectively arranged with Si Huidun between holder chain conveying mechanism 8 and middle plug conveyer device 2 and move steel construction 9, described Si Huidun steel moving mechanism 9 is connected on the pedestal of plug conveying carrier roller 3.
Plug rollgang 6 includes multiple the second plug conveying carrier roller carrying roller 10 being arranged on pedestal 1 by bearing block, the corresponding reductor 11 driving the second plug conveying carrier roller 10 to rotate of each second plug conveying carrier roller 10.
The carrying roller of middle plug conveyer device 2 adopts liftable carrying roller.
The operation principle of the present invention:
After tandem mill 10 tube rolling terminates, steel pipe is deviate from by sizing mill, leave tandem mill, the stopper mechanism of clamping plug drives middle plug conveyer device 2 rollback in plug A edge leaving tandem mill, after rollback puts in place, the stopper mechanism of clamping plug is opened, Si Huidun moves steel device and used plug A is pulled out cooling, lubrication A district, cooled down with the bosh 5 asking chain conveying mechanism 8 that plug A is delivered to A district by the plug rollgang 6 in A district, after cooling is good, it is return back on the holder chain conveying mechanism 8 in A district by the plug rollgang 6 in A district and holder chain conveying mechanism 8 again, while rollback, the graphite lubrication mechanism 7 through A district completes greasing.
Plug A is being cooled down, is lubricating simultaneously, cooling, holding in the palm of lubrication B district are provided with, on chain conveying mechanism 8, the plug B cooling down in advance in B district, having lubricated, by Si Huidun shifting steel device 6, plug B is dialled in middle plug conveyer device 2 to carry out wearing rod, roll after putting on. The plug A between at this moment in gap, cooling down, lubricating A district has completed cooling and lubricating, waits that moving steel wears rod.
Repeat said process, it is achieved double-core axle cooling, lubrication.
