As the core pillar of the industrial system, the machinery and equipment manufacturing industry covers multiple subdivisions such as general machinery, special equipment, engineering machinery, machine tool equipment, and agricultural machinery.
Its product manufacturing is based on the core orientation of high strength, high precision, high stability, mass production, and long-term operation and maintenance, while taking into account assembly efficiency and equipment operation reliability requirements.
Threaded connection is the core process for assembling many key parts of mechanical equipment, which directly affects the structural rigidity, operational stability, service life and full life cycle operation and maintenance costs of the equipment.
However, there are many pain points in the traditional threaded connection process.
The traditional tapping process can easily cause the threads of thick plates to slip and be damaged, weakening the strength of the base material, and is inefficient, making it difficult to adapt to mass production needs; welding nuts are prone to thermal deformation, destroying surrounding precision components and the anti-corrosion coating of the base material, and are prone to rust later, and the welds require additional polishing, affecting the accuracy and appearance of the equipment; the connection process of ordinary nuts is cumbersome, inaccurate positioning is prone to thread deviation, and is easy to loosen under complex working conditions, posing safety hazards.
Dunchuan has been deeply involved in the riveting field for many years. Relying on more than 30 core patents, it has launched a series of special rivet guns and pressure rivet nuts suitable for precision manufacturing and maintenance of mechanical equipment.
This series of products covers a variety of products that are suitable for mechanical equipment materials. The specifications cover the full range of M2 – M12. It is equipped with handheld convenient rivet guns and industrial-grade automated rivet guns. It adopts cold-pressed plastic molding technology and perfectly complies with relevant industry specifications. It is fully adaptable to all scenarios of mechanical equipment manufacturing and maintenance.
Dunchuan rivet gun rivet nuts have the characteristics of precise controllability.
Using laser real-time positioning + intelligent pressure feedback + torque monitoring system, the riveting positioning accuracy reaches ±0.03mm, and the pressure error is ≤±2%. It can automatically identify the type and thickness of different high-strength base materials, accurately match the riveting parameters, and ensure that the riveting nut and the base material form a strong mechanical interlocking structure to eliminate safety hazards.
Its nut breaking torque after riveting meets industry standards, which can effectively resist the influence of complex working conditions and avoid problems caused by loose connections.
The cold pressure riveting process has no high temperature, no welding slag, and no burrs. It does not affect the assembly accuracy and appearance of the equipment, and at the same time avoids damage to precision components caused by thermal processing.
The built-in sensor and AI intelligent diagnosis system realize the traceability of the entire process of threaded connection quality. The pass rate of riveting connections is stable at more than 98.5%, and the connection strength is more than 2 times higher than that of traditional tapping connections.
In terms of global adaptation, Dunchuan rivet gun rivet nuts can be quickly adapted to multiple materials and dissimilar material combinations through modular design, efficiently realizing precise connections of various components of mechanical equipment, completely retaining the original characteristics of the base material, avoiding problems caused by improper processes, effectively solving the shortcomings of traditional bolt splicing, and mitigating the hidden dangers of electrochemical corrosion in dissimilar material connections.
In different application scenarios, Dunchuan rivet gun riveting nuts have demonstrated strong adaptability and core advantages.
In the field of general machinery manufacturing, it improves the assembly efficiency of parts and reduces the rework rate; in the field of engineering machinery manufacturing, it adapts to heavy load and anti-vibration requirements and extends the service life of equipment; in the field of machine tool equipment manufacturing, it meets high-precision and anti-vibration requirements and avoids the intrusion of dust and oil; in the field of agricultural machinery manufacturing, it resists the erosion of outdoor operating environments; in the field of equipment on-site maintenance, the handheld rivet gun is easy to operate and improves maintenance efficiency.
Dunchuan pressure rivet nuts are weather-resistant and durable. The core components are specially hardened and anti-corrosion and wear-resistant. They are equipped with multiple anti-corrosion coatings to resist a variety of corrosion. The salt spray test can last up to 1800 hours.
A single rivet gun has a maximum failure-free operation of more than 1.2 million times, and the rivet nut can be used for up to 18,000 hours without failure. Maintenance costs are saved by 60% compared with similar products, and the service life is much higher than the industry average.
In terms of high efficiency and energy saving, the purchase cost of Dunchuan rivet guns and rivet nuts has been reduced by 40%, and energy consumption has been reduced by 25%. A single piece of equipment saves about 21,000 yuan in electricity and consumables annually.
The efficiency of the cold press riveting process has been greatly improved, and with the intelligent production line, continuous batch riveting can be achieved, shortening the processing cycle and increasing production capacity.
The automated riveting unit can be integrated with the MES system to meet the quality system traceability requirements and promote the transformation of machinery manufacturing into lean and intelligent.
With the advancement of Industry 4.0, the demand for riveting processes in the machinery and equipment manufacturing industry continues to increase.
Relying on its core advantages, Dunchuan rivet gun rivet nuts continue to solve the industry’s connection pain points, promote process upgrades and iterations, and become the preferred riveting solution in the field of mechanical equipment manufacturing.
In the future, Dunchuan will continue to deepen its efforts and launch riveting solutions that better meet the needs of segmented scenarios, help machinery manufacturing companies achieve lean production, improve quality and efficiency, and build a core line of defense for precision connections for the high-quality development of the industry.
