Vibration-breaking All-in-one Machine

Availability:
Quantity:

After casting, the small and medium-sized mold is placed on the equipment for vibration sand drop, so as to separate the molding sand from the sand box and casting. The separated sand ball passes through the falling sand frame and falls to the crusher body through the grid hole for crushing and regeneration. It can complete the process of falling sand, crushing of old sand mass, defilm of binder, screening and separation of debris in one time. Motion analysis Although the movement of the sand breaker and the crusher is relatively complex, for the unibody inertia vibration equipment, the vertical motion of the body satisfies the simple harmonic vibration motion equation. Users can adjust the amplitude according to the adjustment of the motor excitation force to meet the needs of the sand falling effect.

1) Vibration motor provides excitation source of simple harmonic vibration system.

When the mold (with or without sand box) is cast up, and then falls and collides with the grid, the sand box is separated from the sand mold, and the casting is separated from the cast mold. After the sand type is broken, it falls to the vibration conveyor or the sand belt through the grid hole. Because the direction of the exciting force is perpendicular to the upper plane of the grid, the casting and the sand box cannot be unloaded, so the lifting equipment is needed to lift away and complete a casting sand falling process. At this time, the grid hole of the sand dropping machine ≤ 45mm falls into the crushing bottom plate of the crusher for the next step of crushing. The falling sand frame is the main structure of the equipment, and the main problem of the vibration equipment is the rigidity of the reference body. Therefore, the structure design mainly considers the rigidity of the reference body, and the aging treatment must be carried out before the frame is processed. If the vibration of the motor is not aging, the vibration itself is a stress release process.

2) The base is used to support the body and spring, so that the frame body, spring and base constitute a monoplast structure.

3) The spring stiffness is mainly selected according to the vibration working area and amplitude of the equipment. Here, the sand dropping machine is selected to work in the far resonance area. The characteristics of this working area are as follows:

(1) Because the amplitude amplification has little effect, the load has little effect on the amplitude.

The spring stiffness is small, the vibration mass is large, the spring is not easy to break, the force passed to the foundation is small, the foundation design is simple, and the influence on the workshop is small.

③ Damping has little effect on amplitude.

(4) Easy to achieve no forced connection of double shaft or double vibration motor drive.

⑤ Starting and stopping all through the resonance area, loud noise.

⑥ To improve the amplitude of the need for a large vibration force, shaker structure size, motor starting power.

4) The sand mass (block) of the crushing body after the falling sand frame body enters the crushing body ≤ 45mm. Due to the directional vibration of the crushing body, the sand block impinges, rolls and vibrates in the crusher body to make the sand block broken, and through the friction between the sand blocks, the adhesive film on the surface of the sand can be removed; After crushing, the sand particles fall from the crushing floor into the sending tank, while the large particles are sifted out into the miscellaneous bucket. The crushing body material is welded by 16Mn steel plate.

5) Materials that cannot be broken when the access door passes through the crushing body, such as firebrick blocks, iron blocks and grass ropes, are discharged by the miscellaneous cleaning door at the back of the crushing basket.
