Chenzhou Ring Multiplier Chain: New Artery for South Hunan Intelligent Manufacturing

I. Chenzhou Smart: Regional Breakout of the Ring Multiplier Chain

Driven by Hunan's "manufacturing province" strategy, Chenzhou relies on theNon-ferrous metal deep processingtogether withEquipment ManufacturingThe dual pillar industry is building a circular multiplier chain as a breakthrough point for regional intellectual upgrading. Unlike the mature industrial chain in the Yangtze River Delta and Pearl River Delta, Chenzhou has chosen a differentiated path.Leveraging local mineral strengths(e.g. high purity aluminium) to develop customized guide rails, and transfer the heavy load experience of mining machinery to the speed chain system, so that the hardness of the rails can be increased to HRC45 or above, and the abrasion resistance can be increased by 30% compared with the conventional product, and this "heavy load gene" has made the Chenzhou production line come into prominence in the heavy industrial scenes, such as the automotive parts. This "heavy-duty gene" has enabled Chenzhou production lines to emerge in heavy industries such as automotive parts - the loop line designed by a local enterprise for Sany Heavy Industry can stably transport 2,000kg of engineering hydraulic parts, which subverts the stereotypical impression that "the South only produces light industrial chains".

II. Core technology: the code of efficiency gains in a closed loop

Chenzhou company's circular multiplier chain innovation focuses onspatial reconstructiontogether withspeed controlTwo major dimensions:

vertical circulation architecture: Adopting double-layer aluminium profile rail (118×100mm specification), the lower empty board return line forms a closed loop with the upper production line, saving 40% workshop space.
Intelligent beat controlThe PLC-programmed stopper triggers a 3-second stop when the pallet arrives at the operating position, which is used in conjunction with a footswitch to achieve "mobile assembly".
Triple Speed Engineering Plastic ChainSuzhou-made chain with Chenzhou's self-developed roller set (D/d=2.5), the measured speed of the work plate reaches 2.8 times the speed of the chain, and the friction loss is only 7% (industry average 12%).

Case: Chenzhou Jinwo designed a 36-metre loop line for Lance Technology, compressing the mobile phone screen assembly beat from 90 seconds to 35 seconds and increasing the yield rate by 18%.

III. Industrial applications: from mining equipment to electronic precision engineering

The cross-border penetration of the ring multiplier chain in Chenzhou far exceeded expectations:

Heavy machinery areaOn the production line of Sany Heavy Industries, the carbon steel roller carries 2 tonnes of hydraulic valve block and passes through the welding station at a speed of 5m/min, with a thermal deformation error of ≤0.1mm.
Electronic precision assembly: The work plate is embedded with anti-static coating, together with conductive wheels (resistance value <10Ω), eliminating micro-current interference in precision chip assembly.
Food packaging innovation: Stainless steel chain + food grade lubricant to achieve 90° steering encapsulation of 120 bags per minute in a chilli bar factory in Chenzhou, 3 times more efficient than belt conveying.

IV. Technology attack: cracking the pain point of ring connection

Chenzhou enterprises throughStructural innovationstogether withMaterial substitutionOvercoming the inherent difficulties of ring doubling chains:

Connection Reliability: AdoptionSide plate pin connection + elastic locking tabDouble fixing (not traditional bolt), tensile strength increased 45%, avoiding the "risk of disconnection" in the operation of large chains.
Compensation for thermal expansion: Reserve deformation gap for long track over 30 metres, adaptive design of 48mm expansion at ΔT=50°C, eliminating track deformation.
Noise Reduction BreakthroughEngineering plastic roller embedded microporous sound-absorbing layer, measured noise ≤ 65dB (industry standard 75dB), creating a "silent workshop" environment.

Local supply chain collaboration accelerates technology implementation - Yongxing Silver provides high-purity silver-coated chain plates, and Zixing Special Steel forges hardened guide rails, forming a "200-kilometre radius industrial circle" and compressing the delivery cycle to 15 days.

V. Green Smart Manufacturing: Chenzhou Programme for Carbon Footprint Reduction

In the face of manufacturing carbon neutrality goals, Chenzhou has explored three paths:

Regenerative braking technology: The kinetic energy is converted into electrical energy and fed back to the grid when the motor decelerates, with a measured energy saving of 23% in a battery factory.
Photovoltaic direct drive systems: Rooftop photovoltaic + DC inverter motors for the plant, 48 tonnes of carbon reduction per year for a single production line.
Modular quick release design: Sprocket set changeover time reduced from 8 hours to 2 hours and equipment life cycle extended to 100,000 hours.

Exclusive insight: Chenzhou ring doubling chain patent number accounted for the province's equipment manufacturing category 23%, but high-end engineering plastic roller is still dependent on imports. If break through this bottleneck, it can pry 5 billion regional market.

Core Q&A about Chenzhou Ring Speed Chain

Q1: Difference in energy efficiency between a loop line and a linear doubler chain?
torus (geometry)Empty plate return no-load designIt saves 35% of electricity compared with linear chain.A factory in Chenzhou measured: annual electricity cost saving of 480,000RMB under the same capacity of loop line.

Q2: Why do automobile factories prefer Chenzhou production line?
hinge onheavy load adaptability① Carbon steel roller bearing ≥2000kg; ② impact resistant guide rail (deformation <0.5mm/m); ③ PLC overload protection response time ≤0.1 seconds.

Q3: What is the most neglected aspect of business maintenance?
Lubricant compatibility! A case shows the misuse of industrial grease in a food factory, resulting in chain corrosion and breakage - be sure to use food grade or high temperature lubricants (100°C viscosity 46mm²/s) according to the scenario.

Q4: How does Chenzhou cope with the competition from the Yangtze River Delta?
according toCustomised servicesBreakthrough: ① free thermal expansion compensation scheme; ② 15 days emergency delivery (industry average 30 days); ③ support load test machine 72 hours.
