Heavy machinery is the core equipment in engineering construction, mining, transportation and other fields. Its manufacturing quality directly determines operation safety and service life.
From excavator booms and crane chassis to mining crusher frames, heavy-duty truck frames, and agricultural machinery track assemblies, heavy machinery components generally use 3-12mm thick steel plates, high-strength alloys and other base materials. They need to withstand severe working conditions such as heavy loads, high-frequency vibrations, outdoor dust, acid and alkali erosion, etc., which place extreme requirements on the strength, stability, and corrosion resistance of the connection process.
Traditional welding is prone to defects such as thermal deformation and cracks. Ordinary riveting has insufficient anti-vibration and anti-loosening properties. Bolt connections are prone to loosening and falling off under heavy load vibration, which has become a key pain point that restricts the reliability of heavy machinery and shortens the service life of equipment.
The Dunchuan (QUESTOK) rivet gun relies on REW riveting core technology and gas-liquid boosting technology to create customized riveting solutions suitable for heavy machinery manufacturing. It runs through the entire process of component mass production, assembly and debugging, and on-site operation and maintenance. It uses precise connections to build a solid foundation for the quality of heavy machinery and help the industry transform into high-end and durable.
Accurately adapt to core scenarios and solve the pain points of the heavy machinery riveting industry.
The core demands of heavy machinery manufacturing are “high strength, high stability, high efficiency, and harshness resistance.” Dunchuan rivet guns solve the pain points of the industry in a targeted manner, covering the four core fields of engineering machinery, mining machinery, heavy vehicles, and agricultural machinery, and providing full-scenario solutions.
Scenario 1: Assembly of core components of engineering machinery, heavy-duty vibration resistance double standard.
Core components such as excavator booms, crane booms, and loader frames are the “stress-bearing core” of heavy engineering machinery. There are many problems in traditional welding and ordinary riveting.
Dunchuan REW riveting gun is equipped with a gas-liquid boosting system. With cold-pressed rotary friction forming technology, it can directly penetrate 3-12mm thick high-strength steel plates without pre-drilling and bevel processing, and drive rivets to form a tight mechanical interlocking structure. The shear strength and tensile strength of the joint are greatly improved, and the maximum riveting pressure can reach 80kN.
The equipment is equipped with a laser-assisted positioning system, which has high riveting positioning accuracy and small verticality error.
After a leading engineering machinery company introduced this solution, the assembly pass rate of the excavator boom was greatly improved, the assembly time was shortened, labor costs were reduced, the joint fatigue resistance was improved, the equipment service life was extended, and the vibration failure complaint rate was reduced.
Scenario 2: Mining machinery parts manufacturing, corrosion-resistant and dust-proof to adapt to extreme working conditions.
Mining machinery components have been serving in extreme environments for a long time. Traditional connection methods can easily cause components to loosen and fall off, increasing operation and maintenance costs and the risk of downtime.
Dunchuan’s closed ring-groove rivet gun is equipped with anti-corrosion special rivets to create a triple protection solution of “sealing + high strength + corrosion resistance”. The closed rivet design can prevent the intrusion of dust and slurry. The rivet surface treatment is corrosion-resistant, key components are wear-resistant, and the equipment has a long service life.
The handheld device is dust-proof and sealed, and the single-point riveting time is short, adapting to the needs of large-scale mass production; large-scale rack assembly can be equipped with automated robotic arms to improve production efficiency.
After a mining machinery company applied it, the corrosion failure rate of components was reduced, equipment downtime and operation and maintenance time were shortened, and a large amount of operation and maintenance costs were saved.
Scenario 3: Heavy truck frame and chassis assembly, efficient mass production adapts to the lightweight trend.
Heavy-duty truck components need to balance connection strength and lightweight requirements, which cannot be met by traditional welding and ordinary riveting.
Dunchuan’s adaptive SPR self-piercing rivet gun is equipped with a material recognition algorithm that can automatically identify the type and thickness of the base material, accurately match the core parameters, effectively avoid potential electrochemical corrosion risks, and achieve damage-free and crack-free connections.
The equipment adopts a magnetic quick-change kit, which has high riveting efficiency and can be seamlessly connected to the automated production line. There are no redundant consumables in the whole process, and the material utilization rate reaches 100%.
In heavy-duty truck frame assembly, the joints are flat and smooth, improving the assembly accuracy of subsequent parts.
After a heavy-duty truck company applied it, the frame assembly qualification rate increased, the daily output increased, the frame was lightweight and weight-reduced, and fuel consumption was reduced.
Scenario 4: Agricultural machinery frame and track assembly, portable and durable, suitable for outdoor operations.
Agricultural machinery parts need to be easily assembled outdoors and long-lasting. Traditional manual riveting has low efficiency and uneven quality, and the joints are easy to rust and loosen.
Dunchuan’s rechargeable hydraulic rivet gun is free from the constraints of cables and air sources. It is equipped with a high-performance lithium battery. It is lightweight and equipped with an ergonomic handle. It can be operated flexibly by one person and is suitable for small spaces and high-altitude working scenarios.
For the assembly of agricultural machinery track assemblies, high-strength anti-loosening rivets are used, which have excellent anti-seismic and anti-loosening properties. The equipment supports electric riveting function, which greatly shortens maintenance time.
At the same time, the equipment has a modular design and a high level of waterproof and dustproof. Ordinary workers can operate it independently after being trained, reducing labor costs.
After an agricultural machinery company applied it, the assembly efficiency of agricultural machinery frames was improved, the outdoor installation period was shortened, later maintenance costs were reduced, and the incidence of equipment field failures was reduced.
Scenario 5: Operation and maintenance of heavy machinery to quickly and efficiently reduce downtime losses.
The later operation and maintenance of heavy machinery is restricted by conditions. Traditional equipment cannot enter the site, and manual operation is inefficient, which can easily lead to long-term equipment downtime.
Dunchuan portable multi-functional rivet gun integrates the dual functions of riveting and riveting without the need for external power supply. The lithium battery can be quickly charged and is suitable for complex operation and maintenance scenarios. The electric riveting function is highly efficient. It can be adapted to a variety of rivets during installation and the single-point riveting time is short.
In view of the pain point of large heavy machinery being unable to move, it can be used with a mobile riveting workstation to reduce operation and maintenance costs and downtime losses.
After an engineering construction company adopted this equipment, the average operation and maintenance time of heavy machinery was shortened, downtime losses were reduced, and the labor costs of the operation and maintenance team were reduced.
