Abstract

The utility model relates to a telescopic sleeve, which is used for a device for sealing a gear box on a rolling machine. A flange and a fixing ring are welded by a telescopic corrugated tube which is made of metal stainless steel. The installation method is that one end of the flange is fastened on a shell of the rolling machine by a screw. An upper fixing ring is welded on a shell on one side of the gear box, and is quickly assembled and disassembled by a locking ring. When the utility model is used, the axial and radical telescoping and shifting of the rolling roller of the rolling machine are free. The utility model can be made into serial products with good sealing effect. The telescopic sleeve cares nothing for steel scalding. No water leaks into he gear box.

Description

Telescopic cover

Telescopic cover relates to the telescopic cover that is used to seal gear-box in the Iron And Steel Industry on the milling train.

Telescopic cover in the current techniques is made with rubber.The friction of milling train gear can make the rubber telescopic cover gall during steel rolling, and the rubber telescopic cover squeezes broken, boiling hot broken after the steel wire rod stockpile collection that regular meeting is come out by mill milling; After the breakage, telescopic cover loses seal action, causes the gear-box water inlet that gear oil emulsification was lost efficacy; The telescopic cover of often changing oil causes labour cost to increase, and Master Cost increases, the oil plant waste, and increase unproductive time, and milling train efficient reduces, and environment is not only dirty but also poor.

The utility model provides the telescopic cover of sealing gear-box on a kind of milling train, adopts metallic material to make its not cracky, long service life, and adopting fast, the mounting or dismounting joint makes installation and maintenance convenient.

Technical solutions of the utility model are as follows:

0.2-0.6mm is thick with the 1Cr18Ni9Ti corrosion resistant plate, presses the size blanking of rolling mill roll axle, is shaped to bellows with Mould Machining, and welding becomes seamless bellows;

With welding technique flange plate is welded on following retaining ring and becomes as a whole on the bellows; Before the welding locking ring is sleeved on down on the retaining ring, then welding; Be worked into this, locking ring is installed in down on the retaining ring, will go up the retaining ring snap close and aim at down the retaining ring snap close and locking ring is screwed, and whole telescopic cover promptly installs.Because last retaining ring is welded on the housing of gear-box one side of milling train, following fixation is blue to be installed on the milling train housing of roll mandrel one side with interior sunk screw.Thereby can drop into steel rolling work by the aforementioned telescopic cover that installs.

The utility model has the advantages that: 1) roll mandrel can stretch, shrink to the adjustment variation with pass;

2) roll radially can twist distortion with the variation of roll gap;

3) steel wire that rolls out is heaped can not scald brokenly telescopic cover;

4) good sealing effect, gear-box can not intake;

5) quick mounting or dismounting connect and can adapt to milling train production, are applicable to that also other mine, machinery, chemical field need the position of the various telescopic covers that are flexible coupling of fast mounting-dismounting to use, and the utility model can become standardization, seriation, standard product;

6) every month, every rolling mill was saved about 50,000 yuans of manpower and cost of fuel.

Description of drawings:

Fig. 1 always schemes for assembly relation of the present utility model, and flexible radiation fins 1 is arranged among the figure, locking ring 2, locking ring handle 3, last retaining ring 4;

Fig. 2 overlooks for the part of flexible radiation fins 1 and partly cuts open schematic representation (partly cuing open because of symmetry adopts);

Fig. 3 looks the full section schematic representation for the part master of flexible radiation fins 1; On flange plate 5 is arranged, metal bellows 6, following retaining ring 7;

Fig. 4 overlooks for last retaining ring and partly cuts open schematic representation;

Fig. 5 partly cuts open schematic representation for last retaining ring master looks;

Fig. 6 Fig. 7 is the locking ring parts drawing;

Fig. 8 Fig. 9 is last retaining ring parts drawing.

Embodiment: 1) with Fig. 7 being benchmark, with 1: 2 ratio, is foundation with the assembly relation and the parts drawing of scheming (1-9), surveys and draws out whole parts machining process drawings;

2) selecting material is upper and lower retaining ring, and locking ring and flange plate are all selected A for use ₃Steel, and bellows 5 selects 1Cr18Ni9Ti steel plate (0.2-0.6) mm;

3) process choice turner, pincers worker and welding technique adopt the argon arc welding technology between different materials;

4) outsourcing seal ring;

5) argon arc welding is connected on 1 radiation fins 6 after being sleeved on down on the retaining ring 7 by locking ring 3, and (argon arc) weldering flange plate 5 is on radiation fins 6;

6), be contained in screw on the milling train housing of roll mandrel one side with the telescopic cover 1 that welds;

7) will go up and be welded on the milling train housing of gear-box one side after the solid ring installs seal ring;

8) will align telescopic cover 1 that locking latch closure, screw install in advance and the locking latch closure alignment of the last retaining ring 4 that is welded, dextrorotation locking ring handle, soon the utility model is contained on the rolling mill.

Claims

1, telescopic cover is characterized in that by flexible radiation fins [1], locking ring [2], and last retaining ring [4] constitutes.

2, telescopic cover according to claim 1 is characterized in that the bellows [6] that welds on the flexible radiation fins makes for the 1Cr18Ni9Ti steel plate of (0.2-0.6.) mm thickness.
