Single hook shot blasting machine

Types of single hook shot blasting machines

The single hook shot blasting machine is a type of shot blasting machine that uses a single hook to hold items during the blasting process. The shot blasting machine is used to remove rust, dirt, and any other forms of debris from the surface of the material. The mechanism involves the use of a drive motor that rotates a turbine disc. Then, the blasting media is released onto the surface of the item through the turbine, ensuring a high level of cleanliness. Single-hook shot blasting machines are commonly used in various industries to prepare the surfaces of components for further processing, such as coating or painting.

• Production line:

  The part is placed on the hook and is blasted when it is traveling along a rail. It is then removed from the line. This process is repeated. It is efficient for businesses to use this option if they are looking for something less automated.

• Turret:

  The hook is in the shape of a turret, so parts with different diameters can be easily placed. The parts will be blasted from the inside and outside at the same time. It is perfect for using on tubular parts.

• Single blast:

  This kind of machine will only blast the part from one side. It is suited for smaller parts that require a quicker turnaround time.

• Multiple blasts:

  In this type, there are multiple hooks that each hold parts that are blasted at the same time. This type of machine is better for use in production facilities where there are a lot of parts, and each one has to go through the shot blasting process.

It is crucial to note that while single hook shot blasting machines are versatile and widely used, the specific application and choice of blasting media should be carefully considered to achieve the desired results without damaging the components being treated.

Specification & Maintenance of Single Hook Shot Blasting Machines

• Specifications:

  The single hook shot blasting machines have various specifications to suit different industrial needs. Key specs include:

  • Blasting Box Size:

    The size of the blasting box differs based on the machine model. Standard slot sizes range from 60 cm x 60 cm x 60 cm to 300 cm x 200 cm x 200 cm or larger. Customers can select a box size appropriate for the maximum workpiece dimension.

  • Work Hook:

    The work hook is compatible with a weight range of 100 kg to 1000 kg per hook. The hook length can accommodate one to six workpieces at a time.

  • Blasting Speed:

    Normal blasting speeds are between 2 m/min to 10 m/min, according to the type and amount of steel shots used. Extra high-speed options, up to 20 m/min, are available for certain models.

  • Dust Collector:

    Each machine couples with a dust collector that conforms to the customer's chosen filtration system and environmental requirements. Collector types include cartridge filters, bag filters, ventilating hoods, etc. The bag or cartridge quantity utilized will vary according to the machine's design and usage conditions.

• Maintenance Precautions:

  A regular maintenance schedule must be followed to preserve the blasting machines' performance. Here are some essential maintenance tips:

  • Daily Checks:

    Each day, before starting the machine, inspect it to confirm everything is in good shape. Look for things like whether the door sealing strips are deformed or damaged, whether there are any loose parts, whether the drive belt tension is too loose, etc. Complete a thorough machine check and start only after everything is normal. Also, check the steel shot level in the storage silo and add more if needed.

  • Weekly Maintenance:

    Carry out more detailed checks every week. During this time, inspect the blasting machine hook for fracture and repair any issues immediately. Look at the cyclone pipeline and filter, clearing any dust or obstructions. Examine the centrifuge and motor bearings and add lubrication or grease as required. Check the main electrical connections. Fasten any loose bits or parts. Also, review and adjust the blasting cabinet's door seals to ensure an accurate yet effective sealing performance.

  • Monthly Maintenance:

    Each month undertake in-depth machine inspections. Look over all wear parts and replace the sealing strips, lining boards, etc., if they exhibit excessive wear. Review the shooting wheel's tension belts for damage or excessive use. Carefully check the filter bags from the dust collector. Remove any that are too dirty and conduct a cleaning process. Also, study the hopper's interior and blasting trays for steel shot recycle pipeline blockages and clean them thoroughly.

  • Quarterly Maintenance:

    Every three months, complete important and extensive system maintenance. Open all access and inspection panels and closely examine the blasting wheel, hook, lining board, and more for wear and tear.

  Critical components need their lubrication or grease to be refreshed or replaced, including the adjusting bolts and bearing blocks. Comprehensive cleaning must be done to ensure no dust accumulates anywhere.

Applications of single hook shot blasting machines

Single hook shot blasting machines are typically used in the manufacturing industry and for repairing and restoring vehicles, particularly in the automotive and aerospace sectors. They can be used to prepare a wide range of surfaces to achieve high levels of cleanliness and better adhesion of subsequently applied coatings.

The following are some typical applications and uses of the single hook shot blasting machine:

• Surface Preparation: The machine is used for blasting surfaces of various materials like metals, alloys, and castings to get rid of impurities like rust, mill scale, oxides, sand, and other foreign materials and achieve a good surface finish for better adhesion of paints and coatings.
• Descaling: Steel components often have scales formed during the manufacturing process. Using a single hook shot blast machine helps remove these scales and improves the quality of the components.
• Deburring: The machine helps remove burrs and other imperfections in cast or machined parts, resulting in smoother components, especially those used in precise assemblies or high-performance applications like automotive or aerospace industries.
• Cleaning: The single hook machine is ideal for cleaning intricate parts and components where manual cleaning is impractical. It helps get rid of foundry sand and other contaminants from complex geometries and hard-to-reach areas, particularly in engine parts, gearbox housings, and structural components.
• Rust and Degreasing Removal: The machine is ideal for removing contaminants, degreasing, and oxidizing layers to achieve a clean and uniform surface ready for further processing in automotive, marine, or aerospace applications.
• Surface Roughening: A single hook machine creates a specific surface profile or roughness to improve mechanical bonding for adhesive, sealants, or coatings in critical areas where adhesion strength is paramount, especially when dealing with high-performance coatings.
• Boosting Fatigue Strength: Single hook machines can be used to improve the fatigue life of high-stressed components by introducing a beneficial compressive residual stress pattern essential for parts subjected to cyclic loading in structural and load-bearing applications.
• Restoration: The machine is used in restoration when an accurately defined surface profile is needed or when metallic surfaces must be cleaned and restored to improve the quality and extend the life of expensive and critical components like those found in jet engines or hydraulic systems.

How to Choose single hook shot blasting machine

Before going for a single hook shot blasting machine, certain factors should be taken into consideration. The following aspects could significantly impact productivity, quality, cost-effectiveness, and satisfaction.
