Shot peening is a surface treatment process that employs small spherical particles (shots) propelled at high velocity to impact a workpiece’s surface, inducing compressive residual stresses and enhancing its mechanical properties. A shot peening machine is the specialized equipment designed to execute this process with precision. The technology originates from the need to combat fatigue failure in metal components, leveraging the principles of plastic deformation and stress induction to extend service life.  

Shot peening is a crucial surface enhancement technique in the manufacturing and engineering industries. It involves bombarding the surface of a material, typically metal, with small spherical particles called shot. This process induces compressive residual stresses on the surface, which significantly improves the material's mechanical properties. The shot peening machine is the equipment that enables this process to occur efficiently and precisely.

The concept of shot peening has been around for decades and has evolved with advancements in technology. It plays a vital role in various sectors, from aerospace and automotive to medical and heavy machinery. By subjecting components to shot peening, manufacturers can enhance their fatigue life, corrosion resistance, and resistance to cracking, ultimately leading to more reliable and long - lasting products.

he wire mesh belt conveyor shot blasting machine has emerged as a highly efficient and indispensable piece of equipment in the realm of surface treatment. This specialized machine combines the functionality of a wire mesh belt conveyor system with the powerful capabilities of a shot blasting process, offering a seamless solution for cleaning, descaling, and enhancing the surface quality of a diverse range of workpieces. In industries where precision surface preparation is crucial for the performance, durability, and aesthetics of products, such as automotive, aerospace, metal fabrication, and foundry, the wire mesh belt conveyor shot blasting machine has become a cornerstone of manufacturing operations.

The core concept behind this machine lies in its ability to continuously transport workpieces through a blasting chamber using a wire mesh belt while simultaneously subjecting them to a high velocity stream of abrasive media. This process not only effectively removes contaminants like rust, scale, old paint, and casting residues but also improves the surface roughness, which is essential for better adhesion of subsequent coatings and enhanced mechanical properties of the materials. As manufacturing demands evolve towards higher productivity, consistent quality, and greater flexibility, the wire mesh belt conveyor shot blasting machine continues to adapt and innovate to meet these challenges.

1.Structural Components of Wire Mesh Conveyor Systems  

The wire mesh conveyor forms the backbone of the machine, typically constructed from stainless steel (304/316) or high-carbon steel (AISI 1060) to withstand abrasive impacts and high-temperature operations. The mesh design varies based on workpiece requirements: plain weave for small parts (0.5-2mm aperture), twill weave for medium components (3-8mm), and crimped weave for heavy-duty applications (10-20mm). For instance, an automotive parts manufacturer might use a 4mm x 4mm mesh for engine valves, while a construction firm processes I-beams on a 15mm x 15mm mesh.  

Tensioning systems are critical to prevent belt sagging, with most models employing automatic hydraulic or spring-loaded tensioners that maintain 1.5-3% strain. A study by the Journal of Industrial Engineering found that proper tensioning reduces wire breakage by 60%, extending belt life to 8,000-12,000 hours. The drive system, powered by 5-30kW servo motors with variable frequency drives (VFDs), allows speed adjustment from 0.3-12 m/min, enabling precise control over blasting duration. For example, a 1m/min speed ensures 60 seconds of exposure for rust removal, while 0.5m/min is ideal for shot peening to achieve 0.2mm deep compressive layers.  

 2.Blasting Chamber Engineering and Abrasive Projection  

The blasting chamber, lined with 12-25mm thick manganese steel or polyurethane tiles, withstands up to 100,000 abrasive impacts per hour. Computational fluid dynamics (CFD) simulations show that optimized chamber geometry—with deflector angles of 35-45° relative to the belt—enhances blasting efficiency by 30%. Blasting wheels, the core energy generators, rotate at 2,800-3,600 RPM and feature 6-8 tungsten carbide blades. A 15kW wheel accelerates steel shot to 75-90 m/s, delivering impact energies of 0.15-0.6J per particle. Modern designs with backward-curved blades reduce energy loss by 20% compared to straight-blade configurations, as confirmed by finite element analysis (FEA).  

The wire mesh type shot blasting machine represents a significant advancement in surface treatment technology, offering a highly efficient and versatile solution for cleaning, descaling, and enhancing the surface properties of various workpieces. This type of machine utilizes a wire mesh conveyor belt as the transportation mechanism, enabling continuous processing of parts through the blasting chamber. The use of a wire mesh belt allows for the free passage of abrasive media, ensuring that workpieces are uniformly treated on all surfaces, making it an ideal choice for industries with diverse production requirements.

Shot blasting, the core process of these machines, involves propelling abrasive particles, such as steel shot, grit, or glass beads, at high speeds onto the surface of the workpiece. The impact of these particles effectively removes contaminants like rust, scale, paint, and other surface impurities. Additionally, it improves the surface roughness, which enhances the adhesion of subsequent coatings and increases the fatigue resistance of the material. The wire mesh type shot blasting machine has become an indispensable tool in industries such as automotive, aerospace, metal fabrication, foundry, and construction, where high quality surface treatment is crucial for product performance and longevity.
