Abstract
The invention discloses a lower scraping knife sleeve of a slag scraping machine. The lower scraping knife sleeve is used for fixedly arranging a lower scraping knife and comprises a knife sleeve body with a knife groove and inclined iron arranged in the knife groove and used for being matched with the knife sleeve body to tightly clamp the lower scraping knife. One side in the knife groove away from the inclined iron is further provided with a butting device, and the butting device is attached to a knife back of the lower scraping knife and fixed in the knife groove in an adjustable mode through a connecting device. By arranging the adjustable butting device in the knife groove additionally, the butting device can be attached to the knife back of the lower scraping knife at any time, the lower scraping knife can be clamped well, the lower scraping knife is prevented from generating bending moment under the counter-force effect of scraping force in a working process, the service life of the lower scraping knife is prolonged, and the production cost is reduced. The invention further discloses the slag scraping machine.

In prior art, refer to Fig. 1, Fig. 1 is the structural representation that in prior art, under Slag Scraping Device, broach shell coordinates with lower coating blade.Be provided with the broach shell 1 of cutter groove to coordinate with the wedge 2 in cutter groove, lower coating blade 3 is clamped.But broach shell may owing to manufacture or lower coating blade 3 causes the cutter groove of broach shell 1 and the knife back of lower coating blade 3 to fit not tight scraping in slag process unexpected collision under Slag Scraping Device.When the knife back of lower coating blade 3 and cutter groove are fitted tight, lower coating blade 3 is in the process removing weldering meat, and its stressing conditions is similar to cantilever beam, and the counter-force of cutting force produces a moment of flexure to cutter hub, the every scraping of lower coating blade 3 once, a cutter hub just experience elastic deformation, by facts have proved, lower coating blade 3 works more than 2000 times, cutter hub just enters the fatigue phase, because cutter hub is through Quenching Treatment, there is not plastic deformation, but rupture in a certain cross section.
Therefore, how to improve broach shell under Slag Scraping Device, make it better clamp lower coating blade, improve the service life of lower coating blade, reduce production cost, become the important technological problems that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention
In view of this, the invention provides broach shell and Slag Scraping Device under a kind of Slag Scraping Device, to make it better clamp lower coating blade, improve the service life of lower coating blade, reduce production cost.
For achieving the above object, the invention provides following technical scheme:
Broach shell under a kind of Slag Scraping Device, for fixedly mounting lower coating blade, comprise the broach shell that is provided with cutter groove and be positioned at described cutter groove and coordinate the wedge for being clamped by described lower coating blade with described broach shell, one side away from described wedge in described cutter groove is also provided with holding device, the knife back of described holding device and described lower coating blade is fitted, and is fixed in described cutter groove by jockey is adjustable.
Preferably, described holding device is cushion block.
Preferably, described jockey is screw, and the sidewall of described cutter groove is provided with tapped through hole, and described holding device holds out against fixing through described tapped through hole by described screw.
A kind of Slag Scraping Device, comprise broach shell under Slag Scraping Device, under described Slag Scraping Device, broach shell is broach shell under Slag Scraping Device as above.
As can be seen from technique scheme, broach shell under Slag Scraping Device provided by the invention, for fixedly mounting lower coating blade, comprise the broach shell that is provided with cutter groove and be positioned at cutter groove and coordinate the wedge for being clamped by lower coating blade with broach shell, one side away from wedge in cutter groove is also provided with holding device, the knife back of holding device and lower coating blade is fitted, and be fixed in cutter groove by jockey is adjustable, by installing an adjustable holding device in cutter groove additional, the knife back of holding device and lower coating blade can be made at any time to fit, better can clamp lower coating blade, avoid under the counter-force effect of cutting force, producing moment of flexure in the lower coating blade course of work, improve the service life of lower coating blade, reduce production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation that in prior art, under Slag Scraping Device, broach shell coordinates with lower coating blade;
The structural representation that under the Slag Scraping Device that Fig. 2 provides for the embodiment of the present invention, broach shell coordinates with lower coating blade.
Detailed description of the invention
The invention provides broach shell and Slag Scraping Device under a kind of Slag Scraping Device, to make it better clamp scraper, improve the service life of scraper, reduce production cost.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 2, the structural representation that under the Slag Scraping Device that Fig. 2 provides for the embodiment of the present invention, broach shell coordinates with lower coating blade.
Broach shell under Slag Scraping Device provided by the invention, for fixedly mounting lower coating blade 3, comprise the broach shell 1 that is provided with cutter groove and be positioned at cutter groove and coordinate the wedge 2 for being clamped by lower coating blade 3 with broach shell 1, in addition, also comprise the holding device 4 be arranged on equally in cutter groove, holding device 4 is positioned at cutter groove one side away from wedge 2, and holding device 4 is fitted with the knife back of lower coating blade 3, and is fixed in cutter groove by jockey 5 is adjustable.
