In order to improve hardness, the wearability and corrosivity etc. of guide and guard, on July 4th, 2005, the applicant has applied for that a patent name is composite Roll Collar, Authorization Notice No. is the patent of invention of CN100402169C, by after the roller matrix surface be made up of straight carbon steel applies one deck hardcoat, vacuum-sintering forms, and described hardcoat is sized mixing by alloy powder to make.Described alloy powder comprises ni-based self-fluxing alloy and rare earth composite coating.Applicant finds after comparative analysis, and the result of use that different alloy powders is applied on hardcoat exists a certain distance.And in use, the whole service life of guide and guards can not be ensured.
Simultaneously, a kind of Titanium alloy guide device (publication No. CN 102641906 A, date of publication 2012.08.22) of Chinese patent, it comprises casing, guide plate is symmetrically installed with in described casing, high temperature steel bar is by the space between two pieces of guide plates, by the symmetrically arranged deflector roll in casing front end, realize deriving; The contact site of described guide plate inner surface and high temperature steel bar is provided with titanium alloy hard layer, chemical composition and the composition proportion (% by weight) thereof of this titanium alloy hard layer and deflector roll are: TiC40, Fe 30, Ni 25, Co 5, adopt vacuum-sintering mode to make.But it is provided with titanium alloy hard layer in the contact site of guide plate inner surface and high temperature steel bar, and adopt vacuum-sintering mode to make, but cause its cost of manufacture short for its service life high, current demand can not be met.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of multi-functional coatings guide and guards, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: multi-functional coatings guide and guards, comprise casing, guide plate is symmetrically installed with in described casing, the space between two pieces of guide plates crossed by high temperature steel bar, by the symmetrically arranged deflector roll in casing front end, realize deriving, described casing front end is installed with support arm, deflector roll is arranged in the fixed shaft hole on support arm by guide roller axis, described guide plate one end is inserted in inside support arm, the stiff end of support arm is arranged on casing by fixed axis, metal-cermic coating is provided with deflector roll outer surface inside described guide plate.
Being symmetrically installed with guide plate in described casing is that horn mouth is arranged, and bell-mouthed the inner is inserted between the support arm of both sides.
Be provided with spring between described support arm and guide plate, spring is fixed between support arm and guide plate by locating dowel.
Described guide plate is fixed on box inside by fixing pivot pin.
Be provided with bearing between described deflector roll and guide roller axis, bearing and guide roller axis contact position are provided with anti-wearing liner.
Described metal-cermic coating be titanium, chromium, aluminium, nitrogen, carbon under plasmoid, be deposited on crossing on steel face of deflector roll and guide plate by electromagnetic field effect.
Compared with public technology, there is following advantage in the utility model: the utility model plates metal-cermic coating at the inner surface of deflector roll and guide plate, impart the functional characteristic of the various excellences such as the excellent wearability of guide and guards, heat resistance, erosion resisting, non-stick steel, greatly extend guide and guards service life.
