Has the advantages that: the utility model discloses an adopt the design of the antifriction plate that the wear-resisting ceramic plate of aluminium oxide made, not only effectively increased the wear resistance of cutter body, improved the instructions for use of cutter body, increased the wearability of cutter body through adopting the antifriction plate to replace carbide moreover for the manufacturing cost greatly reduced of cutter body, and then make more economical and practical of cutter body.
Description
Technical Field
The utility model relates to a roller mill scraper technical field, concretely relates to wear-resisting scraper.
Background
The sand mixer used in the casting industry at present, no matter imported mixer (German EIRICH and Denmark DISA) or domestic mixer, its scraper and paddle all adopt two ways to improve its life, 1, build-up welding tungsten carbide on the relevant working face of scraper and paddle, this way is relatively simple, but the requirement for the homogeneity of build-up welding is higher; 2. and (4) welding a hard alloy block on the related working surface of the scraper in a brazing mode. In the two modes, the bonded hard alloy has longer relative service life which can reach about one year, so that the scraper and the blade which are bonded with the hard alloy are widely applied.
However, when the scraper made of the existing welding hard alloy is used, due to the fact that the hard alloy is high in price, the use cost of the scraper can be greatly increased by adopting the mode, the scraper is not economical and practical enough, and therefore a novel wear-resistant scraper is urgently needed to solve the existing problems.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome the defects of the prior art, the wear-resistant scraper is provided, and the problem that the scraper is not economical and practical enough due to the fact that the use cost of the scraper can be greatly increased by adopting the mode because the hard alloy is high in price when the scraper made by welding the hard alloy is used is solved.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a wear-resisting scraper, including cutter body and antifriction plate, a cutter body lateral wall middle part is provided with the installation screw, a cutter body edge department is provided with the antifriction plate, the antifriction plate include flitch and shaping in the lower flitch of flitch below goes up.
By adopting the technical scheme, the wear-resisting plate is made of the alumina wear-resisting ceramic plate, so that the wear resistance of the cutter body is improved, the use specification of the cutter body is improved, the wear-resisting plate is adopted to replace hard alloy to increase the wear resistance of the cutter body, the manufacturing cost of the cutter body is greatly reduced, and the cutter body is more economical and practical.
Furthermore, the wear-resisting plate is made of an alumina wear-resisting ceramic plate, and the wear-resisting plate is bonded with the cutter body through AK04-1 high-strength structural adhesive.
Through adopting above-mentioned technical scheme, can ensure the wearability of antifriction plate, and realize the reliable fixed of antifriction plate, simultaneously the antifriction plate still can be used in the paddle department on the roller mill in the in-service use process to increase the wearability of roller mill paddle, and then make the use cost greatly reduced of roller mill paddle.
Furthermore, an included angle between the upper pasting plate and the lower pasting plate is 30 degrees.
Through adopting above-mentioned technical scheme, can ensure the reliable laminating of antifriction plate.
Furthermore, the installation screw is formed on the cutter body, and the installation screw has three.
Through adopting above-mentioned technical scheme, the reliable installation of cutter body can be realized with outside bolt cooperation to the installation screw.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
when the scraper that makes for solving current adoption welding carbide is using, because the carbide price is higher, adopt the use cost of this kind of mode meeting greatly increased scraper for the scraper is economical and practical's problem inadequately, the utility model discloses an adopt the design of the antifriction plate that the wear-resisting ceramic plate of aluminium oxide was made, not only effectively increased the wear resistance of cutter body, improved the instructions for use of cutter body, increased the wearability of cutter body through adopting the antifriction plate to replace carbide in addition for the manufacturing cost greatly reduced of cutter body, and then made more economical and practical of cutter body.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the wear-resistant scraper in this embodiment includes a scraper body 1 and a wear-resistant plate 3, a mounting screw hole 5 is provided in the middle of a side wall of the scraper body 1, the wear-resistant plate 3 is provided at an edge of the scraper body 1, the wear-resistant plate 3 includes a top plate 2 and a bottom plate 4 formed below the top plate 2, and the wear-resistant plate 3 made of an alumina wear-resistant ceramic plate is designed, so that not only is the wear resistance of the scraper body 1 effectively increased, but also the wear resistance of the scraper body 1 is increased by using the wear-resistant plate 3 to replace a hard alloy, so that the manufacturing cost of the scraper body 1 is greatly reduced, and further the scraper body 1 is more economical and practical.
As shown in fig. 1 to fig. 3, in this embodiment, the wear-resistant plate 3 is made of an alumina wear-resistant ceramic plate, the wear-resistant plate 3 and the cutter body 1 are bonded by an AK04-1 high-strength structure adhesive, so that the wear resistance of the wear-resistant plate 3 can be ensured, and the wear-resistant plate 3 can be reliably fixed, meanwhile, the wear-resistant plate 3 can also be used at a blade position on a sand mixer in an actual use process, so that the wear resistance of the blade of the sand mixer is increased, and further, the use cost of the blade of the sand mixer is greatly reduced, an included angle between the upper pasting plate 2 and the lower pasting plate 4 is 30 degrees, so that the wear-resistant plate 3 can be reliably attached, the mounting screw holes 5 are formed in the cutter body 1, the number of the.
The specific implementation process of this embodiment is as follows: during the use at first through outside bolt and the cooperation of installation screw 5, come to install the cutter body 1 on the sand scraping frame in the roller mill, then only need make the work of sand scraping frame on the roller mill, can come to strike off the abrasive material on the roller mill inner wall through the scraper, because the antifriction plate 3 that adopts wear-resisting alumina ceramic plate to make has been add on the cutter body 1, make the wear resistance of cutter body 1 improve greatly, the life of cutter body 1 has been improved, increase the wearability of cutter body 1 through adopting antifriction plate 3 to replace carbide simultaneously, make the manufacturing cost greatly reduced of cutter body 1, and then make more economical and practical of cutter body 1.
