Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of automatic lubrication installation that is used for jobbing sheet-rolling mill copper shoe universal-joint spindle.
Background technology
Recently, the medium plate mill in the whole nation has obtained remarkable economic efficiency, in order to obtain bigger economic benefit, each producer is all striving that milling train has been reached under the situation of designed annual production capacity more than 2 times, raising output keeps, the result strengthens mill load, rolling rhythm is accelerated, cause the copper shoe work of slider typed universal joint spindle very heavy, except bearing very big pressure, outside frictional force and the shock loading, also to suffer dust, iron scale, the invasion and attack of moisture and high temperature, under such working environment, keep the good lubricated very difficulty of copper shoe, cause copper shoe insufficient lubrication and heating phenomenon under heavy duty, often to occur, even accident such as burn, seriously restricting carrying out smoothly and economic benefit of producing.Therefore, how to guarantee that copper shoe has good lubricating condition, a difficult problem of avoiding becoming of accident to need to be resolved hurrily.
At present, the lubricating system of jobbing sheet-rolling mill slider typed universal joint spindle has 4 kinds of forms such as hand oiling, drip lubrication, force feed and protective cover lubricate basically.
Hand oiling efficient is low; The drip lubrication fuel consumption is bigger; Pressure oil spout investment is bigger, and takes up space; Roll change of protective cover fuel feeding and inspection connect difficulty of axial ratio, have also increased the workload of demolition, installation protective sleeves when changing roll.
Summary of the invention
The object of the invention provides that a kind of efficient height, fuel consumption, equipment investment are few, demolition, installation automatic lubrication installation easily.
A kind of automatic lubrication installation, form by roll 1, homalocephalus 2, tiger 3, slide block 4, universal-joint spindle 5, tank filler sleeve 6, it is characterized in that having designed on the universal-joint spindle 5 an auto-supply device, fueller comprises oil pipe 7, fixedly snap ring 8, plunger displacement pump 9, plunger displacement pump push rod 10, template 11, poise nut watt template 12, fixedly snap ring 8 is fixing with universal-joint spindle 5 with plunger displacement pump 9 usefulness during connection, and rotate with universal-joint spindle, be fixed on the universal-joint spindle after 6 usefulness copper oil pipes 7 connect from plunger displacement pump 9 to tank filler sleeve, template 11 is fixed with screw with universal-joint spindle holder watt 12 sides.
Its operation principle is as follows:
When rolling mill transmission system universal-joint spindle 5 rotates, be fixed on template 11 on the universal-joint spindle poise nut watts 12 and withstand plunger displacement pump push rod 10 plunger in the plunger displacement pump is moved reciprocatingly, as shown in Figure 1.The universal-joint spindle plunger displacement pump 9 that rotates a circle is finished oil suction and is pressed oily one-period, and therefore, this device work does not need independent power.The drier oil that plunger displacement pump extrudes is delivered to slide block 4 and homalocephalus 2 and slide block 4 and tiger 3 friction surface by the oil pipe 7 that is fixed on the universal-joint spindle, for friction surface provides good lubricating condition, with the heating of avoiding slide block with burn phenomenon.
This lubricating system is very reliable, can regularly add lubricating grease in the plunger displacement pump shoe cream room.
Auto-supply device main body plunger displacement pump 9 is lubricating pumps that are similar to the slant plate type axial plunger pump, plunger displacement pump 9 is made up of tank filler sleeve 9-1, piston 9-2, shoe cream room 9-3, scroll bar 9-4, turbine 9-5, plunger 9-6, protruding dish 9-7, cock 9-8, rocking bar 9-9, returning spring 9-10, roller 9-11, spring 9-12 as shown in Figure 2.
Have shoe cream room 9-3 on the plunger displacement pump 9, spring 9-12 is housed among the shoe cream room 9-3, drier oil is exerted pressure.Be evenly distributed with 4-16 small plunger 9-6 in the plunger displacement pump 9, when cock 9-8 and protruding dish 9-7 (being similar to swash plate) rotation, small plunger is compressed into or is pulled out by protruding dish 9-7, thereby finishes oil suction and oil extraction work.3-8 oil exit pipe 7 of dress on the plunger displacement pump, wherein 1 is used for the plunges pump body self-lubrication, and the individual hinge place that leads to of 2-7 is used for the lubricated of universal-joint spindle copper shoe in addition.
When β, plunger rotate with cylinder body again in cylinder bore relatively cylinder body axially move and finish and suck and the work of removal of lubricant.
In the end of plunger displacement pump push rod roller 9-11 is housed, roller 9-11 contacts with template 11 on connecing spindle balance device holder watts 12.Universal-joint spindle 5 whenever circles, roller 9-11 just moves once along template 11, thereby promote push rod 10 and drive rocking bar 9-9 swing, rocking bar 9-9 drives worm gear 9-5 in worm screw 9-4, the cylinder body again and the protruding dish 9-7 in the cock rotates, and the small plunger 9-6 that finally promotes around the pump housing produces reciprocating motion.4-16 small plunger 9-6 arranged on the plunger displacement pump, and when fill with lubricating grease in cylinder body after, along with the rotation of universal-joint spindle, the plunger around the pump housing just can be finished oil suction oil extraction work, thereby to the oil site fuel feeding.Transport to slide block from the drier oil that plunger displacement pump extrudes by being fixed on the oil pipe that connects on the body.This lubricating system need not carry out deep hole machining connecing on the axle, and auto-supply just when connecing the axle running only.
Because returning spring 9-10 is housed, therefore push rod of every promotion can both automatically reset, and like this, along with the rotation of universal-joint spindle 5, the plunger on the pump housing will produce periodic reciprocating motion.Meanwhile, the delivery rate of plunger displacement pump also depends on the rotating speed of universal-joint spindle, and the rotating speed of universal-joint spindle is big more, and delivery rate is also just big more.
The drier oil plunger displacement pump is good because of its sealing, does not need to transform the universal-joint spindle structure again, so be a kind of dynamical lubricating system for the very abominable copper shoe of condition of work, its advantage mainly shows the following aspects.
1, do not need independent power
The drier oil plunger displacement pump is simple and compact for structure, and does not need external impetus, and is easy to adjust, good manufacturability.
2, oil mass is adjustable, fuel consumption is low
Owing to be subjected to the restriction of working environment, universal-joint spindle roll side slide is difficult to carry out closed lubricated, generally all be to be under a kind of incomplete lubricating status, and the axle that connects that the fluid that the lubricating system that uses other is supplied with is rotated easily throws away, so not only can cause a large amount of wastes of lubricating oil, also can pollute surrounding environment.If employing drier oil plunger displacement pump is lubricated, it is lubricated with regard to satisfying then only to need to supply with a spot of lubricating grease, pollutes little.The big I of fuel delivery is by selecting the several work in interior 4-16 the plunger of drier oil plunger displacement pump, and all the other are standby, and 7～8 of general jobbing sheet-rolling mill selections, heavy and medium plate mill are selected 9～10 and got final product.Local flow improvement through to the copper shoe structure can make lubricating grease relatively be evenly distributed in lubricated surface, has improved lubricating condition greatly.
3, sealing better
Lubricating grease can also play the effect of sealing, prevents the intrusion of iron scale, dust and moisture, reduces the abrasive wear that connects a surface of friction pair.
4, lubricating grease replenishes conveniently
The oil mass of the shoe cream room in the drier oil plunger displacement pump more after a little while, being exposed at the telescopic oil ga(u)ge pole length of pump housing afterbody will shorten, and remind the attendant in time to refuel, refueling time can utilize when relieving and carry out.
