Continuous Overhead Rail Shot Blasting Machine

Overhead rail shot blasting machine is a hanging chain continuous shot blasting equipment, it has automatic rapid delivery and positioning, workpiece rotation shot blasting cleaning. Suitable for large quantities, cast steel, cast iron, and welded parts of the full range of shot blasting cleaning, for various forms of hanging workpiece. Through the shot blasting cleaning, not only can remove the rust on the surface of the workpiece, clean off the weld slag on the structural components, but also eliminate the welding stress of the workpiece, improve the fatigue strength of the workpiece, increase the paint film adhesion when the workpiece is sprayed with paint, and ultimately improve the surface of the entire workpiece and the internal quality of the purpose.

Key Features of Overhead Rail Shot Blasting Machine

Overhead rail shot blasting machine mainly consist of blasting chamber, blast wheel, workpieces transport system, screw conveyor, bucket elevator, separator, dust collector, electric control system and others.

Continuous overhead rail shot blasting systems are among the most flexible shot blasting system types. They are used for a variety of workpieces for rust removal, descaling, final sanding, deburring and finish blasting of delicate components or for roughening of surfaces for a subsequent coating. They are generally available as batch or continuous systems, but numerous intermediate forms also exist based on the hanger-type rail system. Different processes such as blasting, painting and subsequent drying can in many cases be linked through the hanger-type system, exploiting enormous rationalisation potential.

Work pieces are hung individually or in clusters onto rotating hooks that are fixed on trolleys on the transport rail. The transport rail may be produced in different lengths and with a different number of trolleys. At the beginning of a cycle, a cluster is moved into the machine, the door closes, and shot blasting commences. During shotblasting, work pieces on rotating hooks are spun in turbine jets, thus achieving uniform blasting of all surfaces. At the end of the cycle, the door opens, the blasted cluster is moved out of the machine, and on the other side a new cluster is moved into the machine.

Advantages of Overhead Rail Shot Blasting Machine

High Efficiency:

Overhead rail shot blasting machine adopts a series of high-efficiency process and design, making the blasting process faster and more efficient. The contour of the suspension chain is well-designed, and the movement of the metal parts on it is more stable.

Energy saving:

Due to the high efficiency of the working principle and design, it is more efficient than the other machines. Compared with other shot blasting equipment, it can be more effective use of energy, reduce energy waste. This is an important role in improving industrial production efficiency and saving production costs.

Types of Overhead Rail Shot Blasting Machine

The overhead rail shot blasting machine according to items features, size and the production capacity divided into continuing through type overhead rail shot blasting machine, step-through type overhead rail shot blasting machine, and accumulation type overhead rail shot blasting machine.

Continue through type overhead rail shot blasting machine is not only can be used with the coating line but also can use as a single machine. The continue through type as its name can working continues. When one workplace is blasting, the other one can loading and unloading the items. The machine can highly improve the working efficiency and it also can save labor and cost.

Step-through type overhead rail shot blasting machine working principle is when the one item into the blasting chamber and start to blasting, the door will be closed and the item rotary in the chamber. After blasting is completed, the door opened and the item is out of the chamber. Users can according to their item’s requirements to adjust the cleaning time to control the productivity and cleaning effect. This machine realizes a double working place for blasting and unloading items.

Accumulation type overhead rail shot blasting machine is designed according to the object items’ requirements. The users can perform intermittent work on the machine according to the situation. The hook walking trough on the shot blasting machine adopts a three-stage sealing protection method of flexible steel core rubber plate, nylon brush, and air-controlled pull cover plate, with a good sealing effect.

Operation of Continuous Overhead Rail Shotblasting machine

Study the working principle of the shot blasting turbines, analyze the cleaning and strengthening effects of the shot blasting turbines and calculate the theoretical data of the basic performance indicators of the shot blasting turbines.

According to the actual production and processing overhead rail shot blasting machine, a three-dimensional model of its shot blasting turbines and chamber body is established to provide a basis for software analysis.

Use the ADAMS simulation model to analyze the movement state of the abrasive, combine several theories of the abrasive analysis in the literature and select an appropriate method for software simulation. Considering the influence of air resistance, gravity, throwing angle and throwing distance, the impact process of the abrasive is analyzed and verified by calculation.

Use ANSYS/LS-DYNA to analyze the guard plate in the blasting chamber, to get the corresponding stress diagram and maximum stress and improve the design scheme.

Nowadays, many customer chose to use the overhead rail shot blasting machine. That because this machine not only can use single, but also can working with the painting and curing oven as a production line.

However, when we use the machine, it should be operated in strict accordance with the production standards. Otherwise it will not only cause damage to the equipment, but also cause physical injury to the operator.
