Description

A kind of roll body flusher

Technical field

The utility model relates to cold rolling GRINDING FOR COLD STRIP, belongs to a kind of roll body flusher that roll body grinding preceding operation in cold rolling mill grinding roller workshop is prepared usefulness more precisely.

Background technology

The grinding task of each all kinds of roller in unit of full factory will undertaken in cold rolling mill grinding roller workshop; particularly the roll body reconditioning quantity of working roll is in the majority; all kinds of working rolls after rolling off the production line; intermediate calender rolls; backing rolls etc. are because there is uniform temperature in roll body self; simultaneously on the roll body surface or diameter of axle remained on surface contain a large amount of greasy dirts; after removing bearing; also uncolled roll body under environment temperature; consider the metal principle of expanding with heat and contracting with cold; roll body is can not directly go up grinding machine to process; run into when producing high trade mark hardness steel or battle wagon plate; because reversing roller is frequent; Shi Changhui working roll occurs and intermediate calender rolls can't satisfy user's rhythm of production; cause the roller problem for the treatment of of producing; be generally such problem of solution, interim leaning on manually to all kinds of working rolls; intermediate calender rolls; the backing roll roll body carries out the cooling while cleaning, so that the roll body temperature reaches environment temperature; therefore, there is following subject matter in traditional single manual washing and cleaning operation:

1. when producing high trade mark hardness steel or battle wagon plate because reversing roller is frequent, the time regular meeting working roll appears and intermediate calender rolls can't satisfy user's rhythm of production, cause to produce and treat the roller problem, limited the operating efficiency of crucial production line to a certain extent;

2. manually hand-held sebific duct washes roll surface and cools off, flush points is limited, and in the flushing operation of roll body both sides, randomness is bigger back and forth, developing result is relatively poor, flush efficiency is low again, and according to the preliminary statistics, washing a working roll needs about 15 minutes, the running water that splashes brings very big influence for the operation surrounding environment, simultaneously, ground is wet and slippery, the operating personnel is walked back and forth have certain potential safety hazard;

3. flushing roll body running water is to enter trench after once using, and the wasting of resources is bigger.

Summary of the invention

The purpose of this utility model provides a kind of roll body flusher, can be implemented in cooling is washed in differential roller footpath and the long roll body of differential roller, and the liquid after the flushing is concentrated and reclaimed after filtration, improves the production operation environment, and high rhythm serialization is produced.

For achieving the above object, the utility model adopts following technical scheme:

A kind of roll body flusher, it comprises, fixed mount, it is a frame structure, adopts four channel-section steels to form; Movable stand, it is a frame structure, is arranged at the fixed mount inboard; These movable stand two outsides are equipped with respectively-pulley and-slide block, four channel-section steels of corresponding fixed mount move in channel-section steel respectively; Be provided with a crossbeam in the middle of along its length in the movable stand framework; Lift cylinder, the one end is connected under the fixed mount, and its piston rod end is connected in movable stand; Swing mechanism, it comprises, oscillating cylinder, the gudgeon formula was connected in movable stand framework and crossbeam in the middle of the one end adopted; Hollow shaft is arranged on the movable stand by bearing block, and the one end is by the outer water receiving/source of the gas of tube connector; First crank, one end and cylinder piston boom end flexibly connect, and the other end is connected with an end of hollow shaft; Second crank is connected on the hollow shaft axle body; Carriage, it is connected on second crank, along the carriage length direction some supports is set, and its rear end connects a counterweigh block; Cantilever beam, it is a pipe structure, is communicated with hollow shaft by tube connector; Its rear end is arranged in the carriage support, and cantilever beam length direction both sides, free end upper edge are provided with some jet pipes and respective nozzles.

Further, also comprise a roll bracket, this roll bracket bottom is the backflash of a recyclable flushing water.

Again, tube connector described in the utility model comprises flanged bent tubular body that is arranged at swivel joint on the movable stand, is connected with swivel joint and the rubber hose that is connected with flange.

In addition, a pair of bearing diagonal and a connecting rod of booster action have also been established under the described movable stand.

Connecting rod also is set between each jet pipe on the described cantilever beam.

The utility model can be realized cooling is washed in differential roller footpath and the long roll body of differential roller, each position up and down that mobile framework has roll body reaches omnibearing developing result by the driving mechanism up-and-down movement, liquid after the flushing is concentrated and is reclaimed after filtration, has repeatedly and uses.

The beneficial effects of the utility model

Owing to adopted the roll body flusher, change must be by manually carrying out when cleaning the cooling roll body in the past, the running water that splashes causes operating environment poor, wearing operative employee's health of raincoat operation must be perspired by vexed, nowadays the semi-automatic pouring operating type that dashes has replaced traditional artificial flushing mode, greatly reduce operating personnel's labour intensity, simultaneously the more rational again human resources of having brought into play.

The utility model device comes into operation, semi-automatic dashing drench operation make originally wash a roll body need spend time of 15 minutes shortened near half, guaranteed to supply with the crucial rhythm of producing unit with the assembling roller.

The utility model device comes into operation, and the recirculated water control system is changed into repeatedly used flushing water for industrial use with traditional disposable flushing with running water, has saved resource.

The utility model device comes into operation, and changes in the past the wet and slippery operating personnel of making on ground and walks back and forth and have certain security hidden trouble.
