As the core support for energy and resource development, mining equipment has long served in extremely harsh working conditions such as heavy load impact, dust diffusion, drastic temperature changes (-30°C~60°C), and slurry erosion. The connection quality of its core structure directly determines the equipment’s operation safety, operating efficiency, and service life.
As the mining industry transforms into large-scale, intelligent, and green, traditional processes are no longer able to meet the stringent connection requirements of mining equipment.
Solid rivets have become the preferred connection solution for mining equipment manufacturing due to their core characteristics of high strength, fatigue resistance, loosening resistance, and wear resistance. Dunchuan rivet guns rely on precision riveting technology and are specially optimized for mining working conditions to break the bottleneck of traditional processes and provide efficient, reliable, and compliant connection solutions for the entire process of mining equipment manufacturing, assembly, and operation and maintenance, helping the industry improve quality, efficiency, and safety upgrades.
The field of mining equipment manufacturing has its unique core requirements for solid rivet riveting technology and equipment, which focus on five major aspects: heavy-duty impact resistance and anti-loosening, adaptation of thick plates and wear-resistant materials, durability in dust environments, efficient adaptation to mass production, compliance and durability, and cost controllability.
With the core of “high precision and heavy load, thick plate adaptation, dustproof and durable, efficient and convenient”, Dunchuan rivet gun deeply integrates riveting accuracy, load-bearing capacity and economy, combined with special optimization of mining working conditions, to form a unique advantage that fits the mining scene. It has been verified by leading enterprises such as XCMG, Sany Heavy Industry, Lingong Heavy Machinery and other actual operations, and can fully meet the stringent connection needs of mining equipment.
In terms of precise pressure control and heavy-duty vibration resistance, Dunchuan rivet gun is equipped with an advanced system. The pressure error, positioning accuracy and verticality error are all controlled within a very small range, and can accurately adapt to various specifications of solid rivets and thick plate substrates.
REW radial extrusion cold forming technology is used to make the connection joints firm. After high-frequency vibration testing, there is no looseness or displacement, and excellent temperature change resistance. The built-in monitoring system can realize the traceability of the entire process of riveting quality. The riveting pass rate is stable at more than 99.9%, strictly following industry standards.
Cold forming technology is a highlight of Dunchuan rivet gun. It adopts cold pressing and static pressure forming process, without adverse effects such as high temperature in the whole process. It can completely retain the properties of the base material and the integrity of the coating. It can realize precise riveting of thick plates, adapt to the connection of dissimilar materials, effectively replace the traditional welding process, and use special rivets to cope with complex corrosive environments.
After forming, the surface of the joint is highly flat and does not require secondary polishing, which not only improves quality but also improves production efficiency.
In terms of dust-proof and durable design, the core components of Dunchuan rivet gun are made of high-quality materials, with a dust-proof sealing level of IP65 and long trouble-free operation time.
The handheld model is ergonomically designed, while the wireless model is free from the constraints of cables and equipped with a quick-change system, which can greatly improve work continuity.
High efficiency and cost advantages are also its salient features. The single-point riveting cycle is short, the automated model is more efficient, and the automatic nail feeding attachment can achieve uninterrupted operations.
Low procurement costs, low energy consumption, low operating thresholds, low rework rates, and fast after-sales service response can effectively reduce comprehensive production costs and enhance corporate competitiveness.
Dunchuan rivet guns have been widely used in many key links in the manufacturing, assembly and operation and maintenance of mining equipment, such as crushers, mining trucks, conveyors, tunnel boring machines and other core equipment.
In the application of different equipment, it has shown advantages such as improving connection strength, extending service life, improving assembly efficiency, reducing failure rate and maintenance costs.
In the future, with the further transformation of the mining industry, the requirements for solid rivet riveting technology will continue to increase.
Dunchuan will continue to delve into the field of mining machinery riveting, optimize product performance, launch customized solutions, expand product categories, strengthen cooperation with leading companies, and help the high-quality development of my country’s mining machinery industry.
