Abstract
The invention discloses a disassembling and pressing adjustable support used for overall disassembling of a short-stress rolling mill and a method. According to the disassembling and pressing adjustable support used for overall disassembling of the short-stress rolling mill and the method which are provided by the invention, the structure is simple, the cost is low and operation is easy and convenient. The disassembling and pressing adjustable support used for overall disassembling of the short-stress rolling mill comprises a right-hand supporting plate and a left-hand supporting plate. The right-hand supporting plate and the left-hand supporting plate are connected in an adjusted mode through a right-hand screw rod and a left-hand screw rod which are arranged on the right-hand supporting plate and the left-hand supporting plate. The widths of the supporting plates are adjusted by manually rotating the screw rods to be adapted to different rolling mills.
Description
Technical field
The present invention relates to short stress rolling mill dismantling technology field, particularly relate to a kind of short stress rolling mill integral demounting dismounting pressure adjustable support and method.
Background technology
In recent years, owing to the little high rigidity of short stress rolling mill profile ensure that the high accuracy of product, negative deviation rolling is easily realized；Can realize symmetry to adjust, this improves operating rate for stable operation, saves maintenance and changes the guide crossbeam time, reducing operating accident, it is to avoid the technology accidents such as rolled piece elbow, impact, curling round the roll, improving the guide and guard life-span significant；Roll change is fast, lumber recovery high, and is more and more used.Owing to the profile of memorial archway milling train is relatively big, milling train height and machine column distance are the biggest, and roll changing time is long, and roll line regulation is got up the reason such as cumbersome so that short stress rolling mill quickly instead of memorial archway milling train metallurgy industry particularly rod line production line on use widely.
Although short stress rolling mill has so many advantages, but still there will be many problems in practice: roller case damage i.e. burn bearing phenomenon；Drier oil sealing leak；Trail run has obstruction or unstable；Roll gap adjustment device runs jam；Bearing flange comes off.Descend maintenance milling train just to become keeping normal life activities the most online to produce, the premise guaranteed the quality.Our factory has just started milling train maintenance outer committee always, and that groped later oneself repaiies, but maintenance troop is huge, milling train disintegrate not only time and effort consuming and also disassemble for destructiveness, cause the waste of spare part, therefore find convenient and strength-saving method and seem the most important.
For a long time, when keeping in repair the milling train that rolls off the production line, it is as follows that milling train carries out disintegration key step:
1, with sledgehammer, screwdown gear is laid；
2, dismantle four dust caps and spacer pin；
3, four adjusting nuts are screwed out successively；
4, top chock is torn open will be unable to lay pressure axle sleeve；
5, successively left and right tension force post is removed together with supporting seat.
When step 1, needing three people, a people buttresses unsettled milling train, and other two people tap pressure base plate simultaneously.This is accomplished by two people and works good, and a people hammers into shape with the right hand, and a people hammers into shape with left hand, and the little rhythm of great efforts all obtains unanimously, the easiest other strength.So tearing open and not only waste time and energy, and easily damage screwdown gear, getting rusty seriously if meeting tension force post pressure axle sleeve.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in construction, low cost, short stress easy and simple to handle
Milling train integral demounting dismounting pressure adjustable support and method.
For reaching above-mentioned purpose, one short stress rolling mill integral demounting of the present invention dismounting pressure adjustable support, it includes right-hand thread gripper shoe and left-hand thread gripper shoe, described right-hand thread gripper shoe and described left-hand thread gripper shoe are connected by the right-hand thread screw mandrel being respectively equipped with on it and the regulation of left-hand thread screw mandrel, manually rotary screw rod regulation gripper shoe width, to adapt to different milling trains.
A kind of short stress rolling mill integral demounting method, it comprises the following steps:
1) milling train that, need to keep in repair rolling off the production line removes roll and the pressure lid of screwdown gear；
2), roll gauge is pressed little, adjustable support is put between top chock and pressure base plate, adjustable support include the positive and negative leading screw of a m24 and two pieces the iron plate of thick 20mm at the positive left-hand thread of same position jewel hole set m24, by rotational lead screw by iron plate be connected and band chamfered part upwards can be placed after regulation with adjustment width；
3), roll gap is amplified to tension force male screw part screw out from adjusting nut completely；
4), supported in screwdown gear, top chock, Zhang Lizhu and left and right successively, step hangs out successively；
5), pull down dust cover and spacer pin, take out adjusting nut and disassemble complete.
The invention difference from existing technology is that the present invention achieves following technique effect:
Use short stress rolling mill integral demounting of the present invention dismounting pressure adjustable support and method can simplify demounting procedure, time saving and energy saving, reduce human cost and be hardly damaged equipment.
The invention will be further described below in conjunction with the accompanying drawings.

Detailed description of the invention
Below in conjunction with embodiment, to the present invention, above-mentioned and other technical characteristic and advantage are described in more detail.
As shown in Figure 1-2, one short stress rolling mill integral demounting of the present invention dismounting pressure adjustable support, it includes right-hand thread gripper shoe 1 and left-hand thread gripper shoe 4, described right-hand thread gripper shoe 1 and described left-hand thread gripper shoe 4 are connected by the right-hand thread screw mandrel 2 being respectively equipped with on it and left-hand thread screw mandrel 3 regulation, manually rotary screw rod regulation gripper shoe width, to adapt to different milling trains.
Short stress rolling mill integral demounting method position:
1, the milling train that need to keep in repair rolling off the production line removes roll and the pressure lid of screwdown gear；
2, roll gauge is pressed little, adjustable support is put between top chock and pressure base plate, adjustable support include the positive and negative leading screw of a m24 and two pieces the iron plate of thick 20mm at the positive left-hand thread of same position jewel hole set m24, by rotational lead screw by iron plate be connected and band chamfered part upwards can be placed after regulation with adjustment width.
3, roll gap is amplified to tension force male screw part screw out from adjusting nut completely；
4, supported in screwdown gear, top chock, Zhang Lizhu and left and right successively, step hangs out successively.
5, pull down dust cover and spacer pin, take out adjusting nut and disassemble complete.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
