Abstract
The utility model discloses a biomass roll-forming combined pressing wheel, comprising a hollow axle and a hollow wheel disc sleeved on the axle, wherein, the hollow wheel disc is connected with the hollow axle by a key; wheel teeth are inlaid on the outer cylindrical surface of the hollow wheel disc and protruded from the outer cylindrical surface. A combined structure is adopted in the combined pressing wheel of the utility model, different kinds of steel are respectively used in different parts of the pressing wheel to realize the functions of the pressing wheel; hard alloy steel with high rigidity and strength is used at the outermost wheel teeth parts where pressure is directly produced, the hollow axle and the hollow wheel disc are made from excellent structural steel. Compared with the pressing wheel made from hard alloy steel in the entire body, the pressing wheel with the combined structure consumes substantially low cost, maintains similar performance and has extremely high performance price ratio.
Description
One, technical field
The utility model relates to a kind of critical component of biomass moulding device, particularly relates to a kind of living beings roll forming combined type pinch roller.
Two, background technology
The living beings technology for compressing and forming develops very fast abroad, and particularly the human residential environment is subjected to today of serious threat, especially the focus of people's attention.In American-European countries,, make that its technology for compressing and forming starting point is higher because basic industries are relatively more flourishing, solid financial strength.For reaching with the Life Design purpose, the pinch roller material that uses generally all is the monoblock type high alloy tool steel, and the cost of raw material of a cover pinch roller product is often very high.Be in the China of developing country, because the national economy income is lower, its technology is promoted and is subjected to serious obstruction.Under the pressure of this, more domestic producers have just used some structural alloy steels and carburizing steel material substitution for reducing cost, consequently,, significantly reduce the service life of pinch roller though cost descends, and only be external 1/3-1/6.Like this, under identical output, change because of serious wear is frequent with regard to causing pinch roller, cause maintenance to shorten at interval, overall cost strengthens.
From the failure mode analysis (FMA) of existing moulding compression pinch roller, owing to have big pressure and temperature at shaping area during work, the pinch roller outer surface because of and softer material come in contact friction, under the pressure and temperature effect, the material molecule is penetrated into mould metallic molecule layout, saboteur's structure, the top layer molecule progressively breaks away from parent and causes the physical dimension of parent to reduce.Other position pressure are less relatively, and it is not obvious to wear and tear.
In view of above analysis, puck design becomes the entire body identical materials obviously unreasonable.High-quality high price or low-quality form a contradiction at a low price, are difficult to solve.
Three, utility model content
The purpose of this utility model is the living beings roll forming combined type pinch roller that can reduce cost, not reduce again its anti-wear performance and compressive property in order to address the above problem, to provide a kind of.
The technical solution of the utility model is: a kind of living beings roll forming combined type pinch roller, contain hollow axle and the hollow wheel disc that is sleeved on this wheel shaft, for key connects, be inlaid with the gear teeth that protrude in this face of cylinder on the external cylindrical surface of described hollow wheel disc between described hollow wheel disc and the hollow axle.
The inner cylinder face of described hollow axle is provided with bearing block, the external cylindrical surface of described hollow axle is provided with the shaft shoulder on one side, be provided with annular slot on one side, distance between the annular slot and the shaft shoulder and the thickness of hollow wheel disc coupling are equipped with spacing snap ring in the described annular slot.
The inner cylinder face of described hollow wheel disc cooperates with the external cylindrical surface of hollow axle, is evenly equipped with elongated slot on the external cylindrical surface of described hollow wheel disc, the arc groove for disconnecting between the elongated slot, and the described gear teeth are embedded in the elongated slot.
Described hollow axle and hollow wheel disc are selected structural alloy steel and high-quality structural steel for use.
The described gear teeth are selected hard alloy steel for use.
The beneficial effects of the utility model
Combined type pinch roller of the present utility model, by adopting combining structure, adopt different steel grades to realize the function of this pinch roller at different parts respectively, wheel tooth position at the outermost direct generation pressure of this pinch roller adopts hardness and intensity all than higher hard alloy steel, and its hollow axle and hollow wheel disc adopt high-quality structural steel.Such combining form adopts the pinch roller of hard alloy steel with respect to entire body, and cost can significantly reduce, and the pinch roller difference of its performance and entire body employing hard alloy steel is not very big, and cost performance is high.
Owing to adopt fabricated structure, can realize the exchange of monomer, the maintenance cost between its operating period also reduces much, all changes whole pinch roller need not be as the pinch roller of original entire body structure at every turn.

Five, the specific embodiment
Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3, scheme a kind of living beings roll forming combined type pinch roller, contain hollow axle 3 and the hollow wheel disc 2 that is sleeved on this wheel shaft, be that key 5 connects between described hollow wheel disc 2 and the hollow axle 3, be inlaid with the gear teeth 1 that protrude in this face of cylinder on the external cylindrical surface of described hollow wheel disc 2.The inner cylinder face of described hollow axle 3 is provided with bearing block 3-2, the external cylindrical surface of described hollow axle 3 is provided with shaft shoulder 3-1 on one side, be provided with annular slot 3-3 on one side, distance between annular slot 3-3 and the shaft shoulder 3-1 and the thickness of hollow wheel disc 2 coupling are equipped with spacing snap ring 4 in the described annular slot 3-3.The inner cylinder face of described hollow wheel disc 2 cooperates with the external cylindrical surface of hollow axle 3, is evenly equipped with elongated slot 2-1 on the external cylindrical surface of described hollow wheel disc 2, the arc groove 2-2 for disconnecting between the elongated slot 3-1, and the described gear teeth 1 are embedded among the elongated slot 2-1.Described hollow axle 3 and hollow wheel disc 2 are selected structural alloy steel and high-quality structural steel for use.The described gear teeth 1 are selected hard alloy steel for use.
This living beings roll forming combined type pinch roller, by knockdown structure, under the prerequisite that guarantees its anti-wear performance, compressive property, reduced the cost of raw material fully, an old saying that has demonstrated fully China " uses the best steel to make the knife's edge ", damage for a certain part that in use occurs, can change separately, further reduce maintenance cost.
