Drainage pipe forming machine

The core characteristics of the drainage pipe forming machine are strong material adaptability, high degree of automation, and stable forming accuracy. Maintenance needs to be carried out around mechanical components, hydraulic/electrical systems, and vulnerable parts. Regular maintenance can extend equipment life and improve production quality.

1、 Core features (differentiated by material type)

1. Metal material drainage pipe forming machine (cold bending/rolling type)

Process friendly: Adopting cold bending technology, processing at room temperature does not damage the metal coating and material properties, resulting in a smooth surface and high strength of the finished product.

Flexible and efficient: It can adapt to different cross-sections such as circular and square by changing the rolling mill, supporting the processing of 0.3-1.2mm thick metal sheets, with a forming speed of 10-25m/min, and continuous automated production.

Precision controllable: The PLC control system is paired with multiple customized rolling rolls, with a diameter/side length error of ≤± 0.3mm and a length cutting accuracy within ± 2mm, suitable for the standardized requirements of building water drainage systems.

2. Cement/concrete material drainage pipe forming machine (suspended roller/centrifugal type)

Strength adaptation: For municipal engineering requirements, heavy-duty drainage pipes with a diameter of 300-3000mm can be processed. The finished product is compressive and corrosion-resistant, and can meet deep burial and heavy load scenarios.

Process specific: Suspended roller models focus on compactness, centrifugal models focus on production efficiency, and vertical vibration models can be customized with non-standard specifications to adapt to different engineering volumes.

Durable and stable: The body is made of thickened steel or H-beam, and the core components are quenched/tempered to withstand the load and vibration during high-intensity operations.

2、 Standardized maintenance methods

1. Daily maintenance (before and after daily work)

Cleaning inspection: Clean the waste, dust, and residual raw materials (metal shavings or cement slurry) from the machine body, rollers, and feed inlet to avoid jamming and affecting the forming accuracy.

Lubrication supply: Add lubricating oil (mechanical oil for metal models and high-temperature resistant grease for cement models) to rotating parts such as transmission chains, gears, and roller bearings to ensure smooth operation.

Electrical and safety inspection: Check whether the wires, plugs, and sensors are damaged or loose, whether the hydraulic system is leaking, whether the safety cover is intact, and idle for 5 minutes to confirm no abnormal noise.

2. Regular maintenance (weekly/monthly/quarterly)

Weekly: Tighten the body bolts and roller fixing screws, check the hydraulic oil/lubricating oil level, and replenish it in a timely manner if it is insufficient; Calibrate the blade clearance of the cutting device to avoid cutting burrs.

Monthly: Polish the surface of the metal rolling mill to remove scratches and attachments; Rust removal and maintenance should be carried out on the pipe molds and hanging rollers of cement machines, and rust inhibitors should be applied.

Quarterly: Replace hydraulic oil and filter elements (hydraulic system), check the operating temperature and vibration values of motors and reducers; Detect the parameter accuracy of the PLC control system and calibrate the length sensor.

3. Maintenance and replacement of vulnerable parts

Metal models: Rollers, cutting blades, and straightening wheels are vulnerable parts. When there is wear, coating peeling, or uneven cutting, they should be replaced in a timely manner; If the rubber pressure roller of the feeding machine ages and slips, it needs to be replaced or refurbished.

Cement model: The eccentric block of the vibration motor and the sealing ring of the pipe mold are prone to wear and tear. Regularly check the elasticity and sealing performance, and replace them immediately if they are damaged; If the lining plate of centrifugal models is severely worn, it needs to be repaired or replaced in a timely manner.

4. Long term shutdown maintenance

Thoroughly clean the inside and outside of the equipment, remove residual raw materials and oil stains, thoroughly remove rust from metal parts, and apply rust proof oil.

Drain the hydraulic oil from the hydraulic system and store it in a sealed container; Key components such as pipe molds and rollers are covered with waterproof cloth to prevent dust and moisture.

Disconnect the main power supply and place the equipment in a dry and ventilated area to avoid electrical faults or component corrosion caused by humid environments.
