1. Universal Pre-Operation Safety Rules for Three Core Devices

BLUF Unified pre-start inspection, power check, and environment confirmation for Aluminum Puller, Single Billet Sawing and Stacking System and Cooling Table avoids mechanical collision, electrical failure and production safety hazards during peak extrusion operation.

Most aluminum extrusion line failures are caused by irregular startup procedures rather than equipment quality problems. Before daily production, operators must perform unified pre-operation checks on the Single Billet Sawing and Stacking System, Aluminum Puller, and Cooling Table to ensure coordinated and safe operation. For the billet sawing and stacking system, workers need to check saw blade tightness, servo positioning accuracy, and mechanical gripper flexibility to prevent loose blades from causing inaccurate cutting or billet dropping during stacking. Any residual aluminum debris on the conveying track must be completely cleaned to avoid jamming and positioning deviation.

For the Aluminum Puller, pre-operation inspection focuses on tension sensor calibration, track smoothness and fixture clamping status. Long-term high-intensity pulling may cause slight deviation of tension data; uncalibrated sensors will lead to insufficient or excessive traction, resulting in profile bending or stretching deformation. Meanwhile, check the Cooling Table’s fan operation and air duct blockage. Dust and aluminum powder accumulated inside the cooling system will reduce airflow uniformity, directly causing inconsistent cooling effect on extruded profiles. In addition, all equipment must run 1–2 minutes of no-load test before formal production to confirm stable operation speed and normal signal response.

2. Exclusive Operation Precautions for Single Billet Sawing and Stacking System

BLUF Subsection The Single Billet Sawing and Stacking System requires standardized feeding speed, fixed-length parameter setting and classified stacking management to prevent billet size errors, material mixing and saw blade damage in mass billet preparation.

As the front-end feeding equipment of the entire extrusion line, the Single Billet Sawing and Stacking System determines the stability of subsequent extrusion, pulling and cooling processes. During operation, workers are prohibited from manually intervening in the automatic feeding and cutting process. Random adjustment of feeding speed will cause saw blade vibration, resulting in uneven billet end faces and length tolerance overrun. When switching billet specifications and lengths, operators must stop the machine first and reset the recipe parameters instead of modifying data during running status, which easily causes program confusion and wrong cutting sizes.

In terms of stacking management, different aluminum alloy grades and different billet lengths must be automatically sorted and placed in designated areas. Mixing 6063 and 6061 billets will lead to overall batch scrap in subsequent extrusion production. In addition, regularly replace worn saw blades and clean the cooling lubricating fluid of the sawing system. Poor lubrication will increase blade wear, reduce cutting flatness, and generate burrs on billet sections, affecting the matching accuracy with the Aluminum Puller traction speed and final cooling quality on the Cooling Table. It is also necessary to check the stacking pallet stability daily to prevent tilting and collapsing during long-term automated stacking.

3. Key Usage Specifications for Aluminum Puller in Extr

The Aluminum Puller works in high-temperature workshop environments for a long time, so temperature adaptation and parameter matching are the core of standardized use. When extruding thin-wall hollow profiles and multi-cavity architectural profiles, operators must reduce traction tension and maintain low-speed stable operation to prevent profile stretching, cracking and internal structural damage. For thick-wall industrial profiles and solid aluminum bars, appropriately increase tension to offset gravity sagging and ensure overall straightness. It is strictly forbidden to blindly increase pulling speed to pursue output, which will cause asynchronous coordination with extruder discharge and produce large-scale curved defective products

During continuous production, regularly check the fixture wear degree of the Aluminum Puller. Worn fixtures will slip during traction, causing local profile distortion and inconsistent linearity. Keep the puller track clean and smooth to avoid foreign matter jamming that affects walking accuracy. When the front-end Single Billet Sawing and Stacking System switches billet specifications, the extruder pressure will change slightly, and the puller parameters need fine-tuning in real time to maintain production rhythm consistency. After daily shutdown, release the tension state to avoid long-term static pressure deformation of mechanical parts, ensuring stable precision for long-term use.

4. Cooling Table Daily

BLUF Subsection: Correct placement rules, regular dust cleaning and wind speed adjustment of the Cooling Table ensure uniform profile cooling, avoid residual stress deformation, and stabilize post-processing surface quality.

Many workshops ignore the standardized use of the Cooling Table, resulting in good front-end extrusion and pulling quality but defective final finished products. After profiles are pulled and discharged by the Aluminum Puller, they must be flatly placed on the Cooling Table in order, without random stacking and overlapping. Stacked profiles cause internal and external temperature differences, forming inconsistent hardness and residual stress, which leads to bending deformation after cooling. For ultra-long curtain wall profiles, ensure the entire profile fits the cooling table surface to avoid suspended deformation during the cooling process.

The Cooling Table’s air supply system needs regular dust removal and maintenance. Aluminum powder and workshop dust accumulated in the air duct will block the air outlet, resulting in local weak wind speed and uneven cooling. According to different aluminum alloys, adjust the cooling wind speed and cooling time reasonably: soft architectural aluminum profiles adapt to gentle cooling, while high-hardness industrial alloys require enhanced air volume for rapid and stereotyped cooling. Cooperating with the precise billet supply of the Single Billet Sawing and Stacking System and the stable traction of the Aluminum Puller, standardized cooling operation realizes full-process quality control and greatly reduces the rework rate of anodizing and spraying processes.
