I. Process details for "bearings & drills"

Bearings and drills are both precision metal parts, which have extremely high requirements for cleaning and rust prevention. Bearings have complex raceways and gaps, and drill bits have deep spiral grooves and cutting edges. Traditional cleaning is difficult to clean thoroughly. The process of this equipment perfectly solves these problems.

Typical cleaning and rust prevention process:

1. Feeding area

· The operator evenly arranges the pending bearings or drills into the conveyor belt or material basket.

2. The first slot: ultrasonic cleaning (main cleaning tank)

· Purpose: Remove heavy oil, cutting fluid, metal debris and other major pollutants.

· Medium: water-based cleaning agent (alkaline or neutral), through heating (usually 50-65°C) and ultrasonic cavating, it quickly peels off stubborn oil stains.

· Technical core:

· Ultrasound: High-frequency vibration produces tens of thousands of tiny bubbles (cavitation effect), which crack in the surface and gaps of the workpiece, generating a strong impact force, and carry out a dead-angle bombardment on the ball of the bearing, the gap between the retainer and the spiral groove of the drill bit, and completely remove the adhesion.

· Heating and spraying: heating reduces the viscosity of oil pollution, and cooperates with circulating spraying in the tank to accelerate the separation of oil pollution.

3. The second slot: ultrasonic rinsing (multi-level optional)

· Purpose: Carry the residual detergent on the surface of the workpiece and the trace amount of oil that has been emulsified.

· Medium: pure water or tap water (heated).

· Function: Ensure that the residue of the main cleaning agent is completely removed, laying a perfect foundation for subsequent anti-rust treatment. Multi-stage rinsing (2-3 slots) has a better effect, usually using "reverse current rinsing" to save water.

4. The third groove: anti-rust treatment groove

· Purpose: Form an extremely thin anti-rust film on the surface of the workpiece to isolate the air and prevent rust.

· Medium: water-based anti-rust agent or dehydrated anti-rust oil.

· Water-based rust inhibitor: environmentally friendly, the surface of the workpiece is not greasy, and there is no need to clean it for subsequent processing. Attached by impregnation or spraying.

· Dehydrated anti-rust oil: suitable for inter-process anti-rust or short-term inventory, with strong anti-rust ability. It can replace the moisture on the surface of the workpiece.

· Method: soaking or spraying.

5. Water cutting (blowing) workstation

· Purpose: Use high pressure, strong wind force at room temperature or hot air to remove residual droplets in the gaps of the bearing and drill as much as possible.

· Importance: This step can greatly reduce the load of the drying section, save energy, and prevent residual water stains.

6. Hot air drying section

· Purpose: Thoroughly evaporate all residual water on the surface and inside of the workpiece.

· Technology: Clean hot air (70°C - 90°C) filtered by high-efficiency HEPA filter, cycle blowing. The hot wind quickly evaporates the water and is discharged out of the box through the humidification system. Make sure that the workpiece is completely dry and free of any water marks.

7. Cooling section

· Purpose: Cool the dried workpiece to close to room temperature, which is convenient for the operator to carry out immediate follow-up treatment (such as testing, oiling, packaging).

· Method: Clean cold air circulation cooling.

8. Discharge area

· The workpieces that have been cleaned, dried, rust-proofed and cooled are sent out, and the operator can collect and package them directly.

II. Core advantages of equipment (for bearings & drills)

1. Extraordinary cleanliness: Ultrasound can penetrate the finest gaps of the bearing and the spiral groove of the drill bit to solve the problems that cannot be solved by manual brushing.

2. High-efficiency oil removal ability: combined with heated cleaning agent and ultrasound, it can quickly decompose and peel off all kinds of lubricating oil and cutting oil.

3. Excellent anti-rust effect: Independent anti-rust process, anti-rust medium can be flexibly selected according to the requirements of the anti-rust cycle to ensure that the workpiece does not rust during processing, transshipment and storage.

4. Complete drying: The water cutting + drying process ensures that the workpiece is absolutely dry and water-free, and avoids secondary rust caused by moisture residue.

5. High automation and consistency: The whole process is automated, avoiding fluctuations in cleaning quality caused by human factors, and the cleanliness of each batch of products is highly consistent.

6. Greatly improve efficiency: Continuous pass-through design, the efficiency of cleaning large quantities of small parts (such as drills and small bearings) is dozens of times that of manual operation of a single machine.

III. Considerations for equipment selection

If you need to consider purchasing or customizing such equipment, you need to clarify the following parameters:

· Workpiece size: determine the size of the equipment tank and the width of the conveyor belt.

· Production capacity requirements: how many kilograms or how many pieces to wash per hour/day determine the length and running speed of the equipment.

· The type and degree of oil stain: determine the formula and cleaning power of the cleaning agent.

· Anti-rust requirements: inter-process rust prevention, short-term inventory or long-term inventory? Decide whether to use water-based anti-rust agent or dehydrated anti-rust oil.

· Venues and public facilities: equipment length, power supply, compressed air, drainage, etc.

Sum up

The pass-through ultrasonic cleaning dryer is a "solution" for handling precision parts such as bearings and drills that require high cleanliness and high rust resistance standards. It integrates multiple optimization processes into an automated production line, realizing the efficient and high-quality transformation from dirty parts to clean, dry and rust-proof finished products. It is an indispensable key equipment in the modern manufacturing industry.
