The utility model provides a kind of novel flexible material cast iron bar, and thick big rectangular bar is designed to comply with counterattack
The bar of formula crusher rotor motion profile and impact force optimum tilt angle shape, improves the service life of bar.And into
One step improves the compactness of bar interior tissue and increases bar integrally shock proof toughness, reduces and occurs in bar use process
The risk of fracture.
The purpose of this utility model is achieved in that
A kind of novel flexible material cast iron bar, including bar ontology, bar ontology is by mounting portion and is located at mounting portion two
The beating part of side is constituted, and has an inclination alpha, the tilt angle and impact crusher rotor at the inclination angle between beating part and mounting portion
Motion profile and impact force match, and flexible material body is embedded in mounting portion.
Above-mentioned novel flexible material cast iron bar, is embedded one layer of flexible material body, or in mounting portion in mounting portion
Center line two sides are at least embedded one layer of flexible material body respectively.
Above-mentioned novel flexible material cast iron bar, the flexible material body of center line two sides is connected by connector in mounting portion
It connects.
Above-mentioned novel flexible material cast iron bar, the connector are spiral.
Above-mentioned novel flexible material cast iron bar, the flexible material body are steel band or bending reinforcement waviness and shape
At steel band.
Above-mentioned novel flexible material cast iron bar, the steel band or bending reinforcement waviness and the material of steel band formed
It is mild steel.
Above-mentioned novel flexible material cast iron bar, the steel strip surface are painted with anti-carburization coating.
Above-mentioned novel flexible material cast iron bar, the inclination alpha are obtuse angle.
Above-mentioned novel flexible material cast iron bar, inclination alpha are 130 ° -165 °.
Above-mentioned novel flexible material cast iron bar, the inclination alpha are 149 °, and bar ontology is rich chromium cast iron bar ontology,
That is the material of bar ontology is rich chromium cast iron.
Compared with the existing technology, the utility model, which has the advantage that, is designed to comply with reaction type thick big rectangular bar
The bar of crusher rotor motion profile and impact force optimum tilt angle shape, improves the service life of bar.It will be flexible
Material is embedded in bar mounting portion, and further the compactness of raising bar interior tissue and increase bar are integrally shock proof
Toughness reduces in bar use process and the risk being broken occurs, improves the service life of bar.The utility model is saved simultaneously
Valuable alloy material, substantially save the cost.
Detailed description of the invention
Fig. 1 is the utility model sectional view.
Fig. 2 be the utility model along Fig. 1 A-A to sectional view.
Fig. 3 is B-B direction sectional view of the utility model along Fig. 1.
Specific embodiment
A kind of novel flexible material cast iron bar as shown in FIG. 1 to FIG. 3, the bar are mounted on impact crushing machine rotor,
The bar includes bar ontology, and beating part 1 of the bar ontology by mounting portion 4 and positioned at mounting portion two sides is constituted, beating part and peace
There is an inclination alpha between dress portion, the tilt angle at the inclination angle matches with impact crusher rotor motion profile and impact force, plate
Hammer beating part is designed according to impact crusher rotor motion profile and impact force optimum tilt angle, embedded in mounting portion
Equipped with flexible material body 1.It can be embedded one layer of flexible material body in mounting portion, can also divide center line two sides in mounting portion
It is not embedded one layer of flexible material body at least.If the exactly center line two sides in mounting portion Fig. 1 are embedded two layers of flexible material respectively, it is
Raising consistency, the flexible material body of center line two sides connects 3 by connector and connects in mounting portion, connector is screw-thread steel
Muscle.
The flexible material body is steel band or bending reinforcement waviness and the steel band formed, when the utility model is tested
Be made with bending reinforcement waviness, steel band or bending reinforcement waviness and the material of steel band that is formed is low-carbon
Steel, the steel strip surface are painted with anti-carburization coating.Flexible material body plays the advantage of internal densener, enhances rich chromium cast iron bar
The consistency of matrix reduces bar internal structural flaw, prevents in because fracture accident caused by internal flaw occurs.Together
When, the flexible material inlayed inside bar can also increase the shock proof toughness of bar, reinforce being implicative of each other between bar, protect
When card bar is integrally broken, is not in that bulk bar is fallen into crusher chamber, causes the great quality accident for breaking entire rotor
Occur.
Inclination alpha between the utility model beating part and mounting portion is obtuse angle, and preferably inclination alpha is 130 ° -165 ° best sides
