Abstract
A kind of syllogic sand crusher machine tooth, belongs to disintegrating machine part, and it is made up of the wing sword on both sides and the main sword of centre, and the upper end of described wing sword is provided with oblique arc rib and top arc rib, and described main sword top is provided with top arc rib, by being welded to connect when described wing sword and main sword are installed.This syllogic sand crusher machine tooth is provided with the main sword and wing sword that are welded to connect; main sword is provided with top arc rib cutting edge; its stressed evenly; anti-impact force is stronger, and the wing sword that brazing connects is provided with oblique arc rib and impulsive force suffered by wing sword can be made much smaller, and under the protection of two flank swords, main sword can be hit greatly more greatly and not easily rupture; even if wing sword or main sword damage; also change separately by melting solder, make its crushing teeth longer service life, maintenance cost reduces.
Description
Technical field
The utility model belongs to disintegrating machine part, is specially a kind of syllogic sand crusher machine tooth.
Background technology
Be in the 3c mono-21cr height cast iron of theoretical research stage at present, in conjunction with all kinds of tup of disintegrating machine, by the Double-metal composite hammer that 3c mono-21Cr rich chromium cast iron and all kinds of carbon steel (containing 45# cast steel, 35# cast steel, 30# cast steel), potassium steel, low-alloy steel etc. form." biliquid " double-metal composite casting process adopted in research and the Technology for Heating Processing of composite casting ensure that metallurgical binding and the metallurgical quality of bimetallic binding site, guarantee that the binding site of bimetallic material is boundary simultaneously, each still keeps the characteristic of each metal material, makes the target that Double-metal composite hammer in use reaches safe, reliable, durable, economic.But this method still cannot effectively crushing teeth be being subject to power when impacting in slowly-releasing sand process, and easily cause the breakage of crushing teeth, service life is short.
Utility model content
The purpose of this utility model is: the syllogic sand crusher machine tooth providing a kind of not easy fracture, maintenance cost lower.
In order to achieve the above object, the technical scheme adopted is: syllogic sand crusher machine tooth, it is made up of the wing sword on both sides and the main sword of centre, the upper end of described wing sword is provided with oblique arc rib and top arc rib, and described main sword top is provided with top arc rib, by being welded to connect when described wing sword and main sword are installed.
Oblique arc rib gradient is 25-30 degree.
The radius of the radian of oblique arc rib and top arc rib is 0.9-1.1 times of crushing teeth thickness.
The oblique arc rib of wing sword is 4 ~ 5 times, top arc rib at the vertical length of the length direction of crushing teeth.
The brazing that is welded as that described wing sword adopts when installing with main sword is connected.
The long 250mm of this crushing teeth, high 26mm, thick 15mm.
The beneficial effect of employing technique scheme is: this syllogic sand crusher machine tooth is provided with the main sword and wing sword that are welded to connect; main sword is provided with top arc rib cutting edge; its stressed evenly; anti-impact force is stronger; the wing sword that brazing connects is provided with oblique arc rib and impulsive force suffered by wing sword can be made much smaller; under the protection of two flank swords, main sword can be hit greatly more greatly and not easily rupture; even if wing sword or main sword damage; also change separately by melting solder; make its crushing teeth longer service life, maintenance cost reduces.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model syllogic sand crusher machine tooth;
Fig. 2 is the scheme of installation of the utility model syllogic sand crusher machine tooth;
In figure, 1-wing sword, the main sword of 2-, the oblique arc rib of 3-, 4-pushes up arc rib, and 5-installs matrix.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is explained.
A kind of syllogic sand crusher machine tooth, it is made up of the wing sword 1 on both sides and the main sword 2 of centre, the upper end of described wing sword 1 is provided with oblique arc rib 3 and top arc rib 4 that gradient is 25-30 degree, and its oblique arc rib 3 is 4 ~ 5 times, top arc rib at the vertical length of the length direction of crushing teeth; Described main sword 2 top is provided with top arc rib 4, is welded to connect when described wing sword 1 is installed with main sword 2 by brazing.
The radius of the radian of oblique arc rib 3 and top arc rib 4 is 0.9-1.1 times of crushing teeth thickness.
The long 250mm of this crushing teeth, high 26mm, thick 15mm.
Two wing swords 1 and main sword 2 are adopted brazing to be welded on and install in matrix 5, also brazing is adopted to connect between wing sword 1 and main sword 2, because crushing teeth adopts high hard antifriction alloy, the impact force at contact of its blade exposed and broken thing is huge, the edge of crushing teeth is easy to fracture, the oblique arc rib 3 of 25-30 degree makes the stressed minimizing of wing sword 1 a lot, it is stressed that the wing sword 1 on both sides can be main its edge of sword 2 slowly-releasing, make all not easy fracture and the damages of winner's sword 2 and wing sword 1, the top arc rib 4 that main sword 2 and wing sword 1 top are provided with adopts arcuation to design, make the stressed sensing center of cutting edge, cutting edge stressed evenly, improve its toughness and wearability, service life improves greatly, crushing efficiency also has and slightly improves.
