Description
Technical field
The utility model relates to mechanical manufacturing field, particularly relates to a kind of magnetic filter scraper plate automatic centring device.
Background technology
Sheet-steel rolling mill's rolling mill production line, uses magnetic filter, its effect be by rolling mill compound inside iron powder and sludge mixture strike off, iron content in controlled rolling oil, ensures the rolling requirements of cold-strip steel.
There are three problems in existing magnetic filter scraping plate mechanism, one is, inordinate wear appears in scraper plate, and scraper plate tooth is often flank wear, instead of overall wear, reduces scraper plate service life; Two are, after scraper plate inordinate wear, the teeth of scraper plate and bar magnet can not normal occlusions, and therefore greasy filth strikes off not thorough; Three are, the flexural deformation of scraper arm, scraper plate and scraper arm are rigidly connected (scraper plate is fastened by bolts on scraper arm), when mud operation scraped by scraper plate on bar magnet, due to the rotation of bar magnet chain row, drive scraper plate to have radial deflection, a radial thrust is produced to scraper arm, this thrust frequently acts on scraper arm, result in the flexural deformation of scraper arm.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of raising and scrapes mud effect, strikes off more thorough, prevents scraper plate inordinate wear, extends scraper plate service life, overcomes the magnetic filter scraper plate automatic centring device of scraper arm stress deformation.
For reaching above-mentioned purpose, a kind of magnetic filter scraper plate of the utility model automatic centring device, described device comprises inverted L shape framework, semi-circular boss is provided with in the middle part of described inverted L shape frame upper side shield, riser is provided with spring centering stretching device, described spring centering stretching device comprises extension spring and connected scraper plate hook, described extension spring end winding support is on the side cover of described inverted L shape framework riser, described inverted L shape framework is provided with two bolt mounting holes, and middle part is provided with a scraper plate mounting-positioning holes.
Wherein said side cover is provided with plug, and described spring is fixed on described plug.
Wherein said bolt mounting holes is counterbore.
Wherein said extension spring is coupling type spring.
The utility model magnetic filter scraper plate automatic centring device difference from prior art is that the utility model achieves following technique effect:
1. improve and scrape mud effect, strike off more thorough;
2. prevent the inordinate wear of scraper plate, extend scraper plate service life;
3. overcome the stress deformation of scraper arm.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As Figure 1-3, a kind of magnetic filter scraper plate automatic centring device, described device comprises inverted L shape framework 1, semi-circular boss 2 (effect is being free to slide after contacting with boss to scraper plate location and scraper plate top) is provided with in the middle part of shield on the upside of inverted L shape framework 1, riser is provided with spring centering stretching device, described spring centering stretching device comprises extension spring 4 (pulling force 3-5 kilogram of coupling type spring selected by extension spring 4) and connected scraper plate hook 6, extension spring 4 end winding support is on the plug of the side cover 9 of inverted L shape framework 1 riser, inverted L shape framework 1 is provided with two bolt mounting holes 3 (for counterbore), middle part is provided with a scraper plate mounting-positioning holes 5 (fixing scraper plate after screwing in bolt).
If Fig. 4 is former scraper arm structural representation, scraper arm front end, on scraper plate installing plate, have installing hole 7 and 8 (there is internal thread in hole 8), during use, two bolts penetrate in installing hole 7, and scraper plate is fastening.
Fig. 5 is the scraper arm structural representation after installing magnetic filter scraper plate automatic centring device, two bolts are penetrated in bolt mounting holes 3, tightening nuts, scraper plate automatic centring device is fixed on scraper arm working end, Fig. 6 is the structural representation after Fig. 5 basis being installed scraper plate, the stretchable holes of scraper plate both sides is enclosed within respectively on the scraper plate hook 6 on centralising device, the extension spring 4 of both sides is made to have certain stretching, bolt is inserted scraper plate locating hole 5, and screw in installing hole 8, adjust bolted (bolt overlap on bolt before screwing in one with the zero diopter pad of its adapted) behind position, better can play the effect of fixing scraper plate), bolt is special counterfeiting an emperor's order hole bolt, bolt screws rear plain cushion and scraper plate has 0.5-1mm gap.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
