Automatic Shot Blast Cabinets
Automatic shot blasting cabinets, also known as automated shot blasting machines, are surface treatment equipment that use the kinetic energy of high-speed projectiles to impact the surface of workpieces, achieving effects such as rust removal, deburring, descaling, and surface roughening. Below is a detailed introduction:
Working Principle
1.Positioning and Loading: The workpiece is placed on a conveyor system or inside a chamber, and the machine ensures proper alignment and secure fixation for efficient cleaning.
2.Projectile Propulsion: The device activates a high-speed blast wheel, which propels abrasive projectiles or grits toward the surface. The abrasive particles strike the surface with controlled force, removing contaminants and creating a textured profile.
3.Dust Collection: During the blasting process, a significant amount of dust and debris is generated. Automatic shot blasting cabinets are equipped with robust dust extraction systems to maintain a clean working environment and protect operators.
4.Abrasive Recovery: These machines integrate an abrasive recovery system to reduce waste and enhance cost-effectiveness. The system collects used abrasive particles, separates them from debris, and recycles them.
5.Surface Inspection: After the blasting process, the surface is thoroughly inspected. Any remaining contaminants or defects are identified and addressed.
Functional Features
1.Automated Operation: Capable of fully automatic operation, the machine automatically completes the entire blasting process according to preset programs, reducing labor intensity and improving work efficiency. For example, the Normfinish Automated Blast Cabinets range can fully automate the blasting process, accommodating various tasks such as depainting, roughening for subsequent coating processes, deburring, shot peening, aesthetic enhancement, and powder removal for products of any size.
2.Precise Control: The machine can precisely regulate parameters like blasting intensity and nozzle movement trajectory, ensuring consistent blasting quality and meeting the processing requirements of workpieces with complex shapes and high precision.
3.Diverse Configurations: Equipped with various fixtures and nozzles, it can accommodate workpieces of different sizes and shapes, offering flexible solutions for diverse blasting needs.
Safety and Environmental Protection: The enclosed structure effectively prevents abrasive splatter and dust dispersion, safeguarding operators' health and safety while reducing environmental pollution. Additionally, it features safety interlocks and emergency stop devices to prevent accidents.
4.Abrasive Recycling: The abrasive recycling system collects and recycles used abrasives, reducing material waste and operating costs. For instance, the AGSCO Corporation's automation kit includes a variable-speed rotating fixture and a rack-mounted automatic blast gun. This simple automation accessory can be installed in almost any cabinet and removed when not needed.
Common Types
1.Suction Blasting Cabinets: Operate on the induction-suction abrasive blasting principle. They are suitable for blasting, deburring, descaling, removing thin deposits on soft metal parts, deflashing plastic items and molded components, and achieving a matte finish. Examples include removing rust and old paint.
2.Pressure Blasting Cabinets: Work on direct pressure blasting. A pressure vessel filled with blasting media is pressurized, and the media is forced through a blast nozzle. Ideal for removing heavy and thick scales, deburring, and deflashing, it uses medium to coarse-grained abrasives.
Wet Blasting Cabinets: Utilize compressed air and abrasive media mixed with a liquid to achieve the desired surface finish. The wet pressure jet can be used for deburring, cleaning, and polishing, producing results similar to those of abrasive shot blasting media. One advantage is the shorter blasting time due to high-volume conveying flow.
3.Satellite Blasting Cabinets: Feature a rotating satellite mechanism that enables precise control of the blasting nozzle's movement trajectory, ensuring uniform blasting of the workpiece surface.
Drum Shot Blasting Machines: Workpieces are placed inside a rotating drum, and the blasting nozzle is fixed. As the drum rotates, the entire surface of the workpiece is blasted.
Conveyor Belt Blasting Cabinets: Workpieces are placed on a conveyor belt that moves them through the blasting area. The blasting nozzle is fixed or moves along a predefined trajectory to blast the workpiece surface.
