Abstract
The utility mode relates to a cracker teeth-roller disc which is a critical part of a cracker teeth roller. The teeth roller disc comprises cracking teeth and a disc body. A tooth sleeve is arranged outside a tooth core; the tooth sleeve and the tooth core are combined and cast into one piece and form the cracking teeth; the tooth core and the disc body form one piece; the tooth sleeve is made of the high-strength and wearable alloy steel; and the tooth core and the disc body are made of the alloy steel of good tenacity, easy cutting, shock resistance and medium intension. The utility model has the advantages of high cracking teeth intension, wearability, accurate location, firm connection, no broken tooth and fallen tooth, long service life, convenient cutting, processing and assembly of the disc body, stable running and high working efficiency. The utility model is applicable to various cracker teeth rollers.
Description
Affiliated technical field
The utility model relates to a kind of disintegrating machine discaling roll dish, belongs to a critical component of disintegrating machine discaling roll.
Background technology
Present known disintegrating machine discaling roll, the employing cylinder that has and crushing teeth use unlike material to cast respectively, weld together then, and this disintegrating machine discaling roll, tooth are difficult for evenly distributing and easy tooth-breaking, fall tooth.Another kind is that cylinder and crushing teeth adopt with a cast molding of a kind of raw material, and it is difficult to solve the contradiction of high strength, wear-resisting and machining, and the big crushing teeth discaling roll casting technique of using for coarse crushing is more complicated, be difficult to reach technological requirement.
Summary of the invention
Provide in order to overcome the deficiencies in the prior art part a kind of bimetal composite casting, crushing teeth intensity height, wear-resisting, dish body good toughness, shock-resistant, the disintegrating machine discaling roll dish of good processability.
The technical scheme in the invention for solving the technical problem is; It comprises breaker teeth and dish body, and its tooth core is integral with the dish body, and the tooth core is provided with the tooth boots outward, and tooth boots and the compound cast solid of tooth core constitute crushing teeth.
The utility model compared with prior art has the following advantages:
1, because crushing teeth and dish body have adopted bimetal composite casting, having solved same foundry goods preferably should crushing teeth high strength, high abrasion has good toughness again, shock-resistant, the easy machining of dish body, be convenient to be assembled into this contradiction of disintegrating machine discaling roll;
2,, thereby the accurate positioning of tooth position, be connected firmly tooth core good toughness, shock-resistant because disintegrating machine discaling roll dish is by tooth boots, tooth core and to coil this bluk recombination cast in block, broken teeth can not occur, fall tooth, long service life, running is steadily, high efficiency, also very convenient when part needs dismounting.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Among the figure 1, the tooth boots, 2, the tooth core, 3, the dish body.
The specific embodiment
As shown in the figure: the utility model is made up of tooth core (2), tooth boots (1) and dish body (3), tooth boots (1) are sleeved on the outside of tooth core (2), tooth boots (1) are integral, constitute crushing teeth with tooth core (2) composite casting, and tooth core (2) also is the casting all-in-one-piece with dish body (3).In actual production process good steel alloy of employing high strength, wearability such as rich chromium cast iron, 30 silicomanganese molybdenum vanadium alloy steel, tungsten alloy steel etc., what the utility model adopted is that 30 silicomanganese molybdenum vanadium alloy steel are cast tooth boots (1) on request, select good toughness for use, easily cutting, 20 chrome-manganese-silicon alloy steels shock-resistant, that intensity is medium are cast into tooth core (2) and dish body (3) and become one, make tooth boots (1), tooth core (2) simultaneously and coil the compound cast solid of body (3) and become breaker teeth roller dish.
Claims (1)
1, a kind of disintegrating machine discaling roll dish comprises crushing teeth and dish body, it is characterized in that tooth core and disk body are integral, and the tooth core is provided with the tooth boots outward, and the compound cast solid of tooth boots and tooth core constitutes crushing teeth.
