Detailed description of the invention

In order to make the technical solution of the utility model more clearly show, below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1 to 6, the utility model provides a kind of Combined type wear-resisting liner plate, for slat conveyer, strengthen the resistance to abrasion of slat conveyer base plate and side plate, this Combined type wear-resisting liner plate comprises grid lining body 10 and is shaped in the liner plate body 20 on grid lining body 10.

Described grid lining body 10 adopts low-carbon (LC), the low-alloy steel of good toughness is made, the shape of this grid lining body 10 is rectangular-shaped, described grid lining body 10 offers and somely runs through the taper hole 11 of upper surface to lower surface, the part between the two adjacent taper holes 11 of described grid lining body 10 forms dowel 12.Taper hole 11 on described grid lining body 10 is in array distribution, and described taper hole 11 is in up-narrow and down-wide pyramid-shaped structures, that is the cross-sectional plane of taper hole 11 on upper surface is greater than the cross-sectional plane of the taper hole 11 of lower surface; This taper hole 11 upper end open is of a size of 40mm*40mm, and lower ending opening is of a size of 50mm*50mm.

Described liner plate body 20 high alloy cast steel is made, and make its hardness reach the scope of HRC58-HRC62, because its hardness number is high, it is wear-resistant, and degree significantly improves.Described liner plate body 20 is rectangular-shaped, this liner plate body 20 is provided with and serves as a contrast the suitable accepting groove of body 10 21 with grid, the bottom land of described accepting groove 21 is convexly equipped with the boss 22 of some array distribution, described boss 22 is in pyramid-shaped structures wide at the top and narrow at the bottom, and the quantity of described boss 22 is corresponding with taper hole 11.The upper end size 50mm*50mm of this boss 22, lower end is of a size of 40mm*40mm.This liner plate body 20 is also provided with 4 fixing threaded holes, 23,4 fixing threaded holes 23 to be positioned at grid with accepting groove 21 and to serve as a contrast on same of body 10, and the corner of the close liner plate body 20 of 4 fixing threaded hole 23 correspondences.In the present embodiment, the quantity of boss 22 is 9.

Further, in order to strengthen the steadiness between grid lining body 10 and liner plate body 20, a left side for described grid lining body 10, right, before, rear each side is provided with firm reinforcement platform 13, firm reinforcement platform 13 is near the lower surface of described grid lining body 10, each side of the accepting groove 21 on corresponding described liner plate body 20 is provided with for accommodating the firm firm strengthening groove 24 strengthening platform 13, due to the described grid lining taper hole 11 of body 10 and the boss 22 of described liner plate body 20 coordinate and described grid serves as a contrast coordinating of the firm reinforcement platform 13 of body 10 and the firm strengthening groove 24 of described liner plate body 20, can ensure to reach more stable matching relationship between grid lining body 10 and liner plate body 20.

When producing the utility model Combined type wear-resisting liner plate, first grid is served as a contrast body 10 casting, be placed in the die cavity of model through impeller blasting after cleaning polishing, pour into a mould through the high alloy wear-resistance molten steel that founding is qualified again, form liner plate body 20, thus make the material of after cast two kinds of unlike materials be combined into an entirety, simultaneously, because liner plate body 20 is high-alloy steel, hardness reaches HRC58-HRC62 scope, therefore after casting complete, be difficult to carry out holing etc. machine up, therefore liner plate body cast before modelling in, prior making fixing threaded hole 23, fixing threaded hole one-shot forming after cast, in process easy to use liner plate body 20 installation.Described grid lining body 10 is fixedly arranged in the accepting groove 21 of liner plate body 20, described grid lining body 10 taper hole 11 agrees with completely with liner plate body 20 taper platform and firmly strengthens platform 13 and is embedded in firm strengthening groove 24, prevents grid lining body 10 and liner plate body 20 from sliding over each other or coming off.Become an overall bi-material to combine firmly through founding, grid lining body 10 plays the effect of densener in the molten steel of high alloy wear-resistance material simultaneously, to make in abrasion-proof backing block body 20, without shrinkage porosite, shrinkage cavity, to make abrasion-proof backing block interior tissue zero defect, dense structure.Meanwhile, high alloy material molten steel wraps grid lining body 10, Yin Gaowen and serves drawing effect to grid lining body 10, makes grid serve as a contrast body 10 toughness and improves further.

The beneficial effect of the utility model Combined type wear-resisting liner plate is: liner plate body 20 and grid are served as a contrast body 10 founding and becomes an entirety, form Combined type wear-resisting liner plate, ensureing under good toughness, the prerequisite that do not rupture, increase substantially the hardness of Combined type wear-resisting liner plate, the final object realizing extending liner plate service life.

The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
