Product Description
Tracked shot blasting machine: Dual-mode selection of rubber and metal tracks - intelligent solution for surface treatment of small and medium-sized workpieces
In industries such as casting, forging, and automotive parts, the surface treatment of small and medium-sized workpieces often faces three major pain points: many cleaning dead corners, easy damage to workpieces, and noise pollution. The tracked shot blasting machine has achieved a breakthrough of 100% surface cleaning coverage and 60% noise reduction through the rubber/metal dual-mode track design and intelligent shot blasting control technology, becoming the preferred equipment for multi-variety and small-batch production. This article will deeply analyze the track selection logic, technical parameter comparison, and 20+ industry application scenarios, providing enterprises with a full-link guide from process adaptation to cost optimization.
1. Core technical advantages of tracked shot blasting machine
Dual-mode track design: precise adaptation of rubber and metal
Rubber track:
Material characteristics: High-strength wear-resistant rubber (Shore hardness 70-80°) with an elastic modulus of 5-8MPa can absorb 90% of the impact force and avoid scratches on soft metals (such as copper and aluminum parts) caused by collision.
Noise reduction performance: operating noise ≤75dB (metal track ≥90dB), in line with GB 12348-2008 environmental protection standards.
Applicable scenarios: precision castings, springs, bearings and other workpieces that are afraid of collision, especially suitable for mixed production of multiple varieties.
Metal track:
Material characteristics: manganese steel forging (hardness HRC50-55), wear resistance increased by 3 times, suitable for processing hard workpieces such as cast iron and forged steel with a unit weight of ≤150kg.
Structural advantages: The chain plate design has a stronger load-bearing capacity and can withstand high-intensity impact at a shot blasting speed of 85m/s.
2. Intelligent shot blasting system (compliant with ISO 11124-3 standard)
Three-speed shot blasting speed: 75/80/85m/s adjustable, suitable for workpieces of different hardness (such as 75m/s for aluminum alloy and 85m/s for cast steel);
BE type separator: shot recovery rate ≥98%, waste sand discharge purity >95%, reducing abrasive loss by 40%;
Pulse bag dust removal: emission concentration <5mg/m³, exceeding GB 16297-2023 standard by 50%, supporting green factory certification.
3. Application scenarios and selection formulas for six major industries
Automotive parts industry:
Gear surface strengthening: metal track + steel shot (S550), shot blasting intensity 0.25mmA, fatigue life increased by 3 times;
Aluminum alloy die casting cleaning: rubber track + glass beads (Φ0.3mm), roughness Ra1.6, qualified rate 99.9%.
Precision casting field:
Copper valve body descaling: rubber track + ceramic sand, processing efficiency 25 pieces/hour, zero scratches;
Stainless steel casting polishing: metal track + stainless steel shot, glossiness increased to G60 (ISO 8503).
Electronic components industry:
Spring stress relief: rubber track + nylon abrasive, deformation <0.05mm, elastic modulus consistency increased by 20%.
Selection calculation formula:
Track length = maximum workpiece length × 1.2 (safety factor)
Number of shot blasters = workpiece surface area (m³) × shot density (200-300kg/m³·h) / single shot blaster processing capacity
4. Technological innovation and maintenance strategy of rubber tracks
Three-layer composite structure design:
Surface layer: high wear-resistant rubber (thickness 8-10mm), Mohs wear <0.01g/time;
Middle layer: polyester fiber reinforcement layer, tensile strength ≥200MPa;
Bottom layer: anti-slip texture design, friction coefficient 0.6-0.8, to prevent the workpiece from slipping.
Life extension plan:
Regular flipping: flip the track every 500 hours for uniform wear;
Elasticity test: Use a Shore hardness tester for monthly testing, and replace if the hardness drops by >10°.
Quick replacement technology:
Modular splicing design, one person can complete the replacement within 30 minutes (traditional metal tracks take 2 hours).
5. Strengthening and upgrading path of metal tracks
Surface treatment technology:
Tungsten carbide coating: hardness increased to HRC65, life extended to 8000 hours;
Laser cladding repair: repair cost of worn parts reduced by 60%.
Noise reduction solution:
Damping sandwich design: embed rubber layer between chain plates, noise reduced by 15dB.
Conclusion: Four core elements of track selection
Material matching: rubber tracks for soft metal/precision parts, metal tracks for hard heavy-duty parts;
Environmental compliance: give priority to equipment with dust emission <5mg/m³ and noise ≤85dB;
Cost control: the comprehensive operation and maintenance cost of rubber tracks is 40% lower than that of metal tracks;
