Tine Carrier Spring Making Machine | CNC Agricultural Tine Spring Manufacturing Solution
The Yinfeng Tine Carrier Spring Making Machine is an automated forming solution developed for manufacturers of agricultural spring tines and related farm machinery components.
Unlike a standard spring coiling machine that mainly produces conventional round compression springs, this equipment is designed for products combining a coiled spring section with long straight arms, angled legs, offset bends, hooks, or customized mounting ends.
The machine can coordinate wire feeding, straightening, coiling, bending, positioning, and cutting according to the required product geometry. This allows manufacturers to produce agricultural spring components with greater consistency while reducing manual bending, secondary processing, and operator dependence.
It is suitable for spring manufacturers, agricultural machinery factories, replacement-parts suppliers, and companies producing customized tine components according to drawings or physical samples.
What Is a Tine Carrier Spring?
A tine carrier spring is a functional agricultural spring component used to collect, lift, move, turn, spread, or guide crops and forage materials during field operations.
Depending on the agricultural machine and product design, the component may include:
One or more coiled spring sections
Long spring-steel arms
Straight or curved tine sections
Offset legs
Mounting bends
Hooked or shaped ends
Symmetrical or asymmetrical structures
Single-tine or double-tine configurations
These products are commonly associated with agricultural equipment such as hay tedders, rotary rakes, balers, pickup systems, forage machines, and harvesting equipment.
Because tine carrier springs operate under repeated vibration, impact, and bending loads, their geometry, material quality, forming consistency, and fatigue performance are important to the final application.

Agricultural Applications
The machine is suitable for manufacturing spring components used in a wide range of agricultural equipment.
Typical applications include:
Hay Tedders
Spring tines lift and spread cut grass or hay to improve drying efficiency.
Rotary Rakes
Long spring tines gather forage into windrows while following uneven ground conditions.
Balers and Pickup Systems
Pickup tines lift hay, straw, or crop material from the field and transfer it into the baling or processing system.
Harvesting Equipment
Spring fingers and tine components guide, collect, or transport crop materials during harvesting operations.
Forage Machinery
Specially formed spring tines are used in machines that move, spread, collect, or process forage.
Cultivation and Soil Equipment
Heavy spring tines may be used for soil engagement, residue movement, weed control, or surface preparation.
Agricultural Replacement Parts
The equipment can support manufacturers producing replacement tine springs for different machinery brands and regional equipment markets.
Complete Forming Process
The production process can integrate several forming operations into one automated sequence.
1. Wire Feeding
The feeding system accurately delivers the programmed wire length into the working area.
2. Wire Straightening
The wire passes through a straightening unit to reduce coil-set curvature and prepare it for stable forming.
3. Coil Forming
The machine forms the torsion or spring coil section according to the required diameter, number of turns, and winding direction.
4. Long-Arm Forming
The wire is fed to create the required tine length or extended spring arm.
5. Multi-Angle Bending
Servo-controlled tools form mounting bends, offset sections, working angles, or special transitions.
6. End Shaping
The machine can form hooks, curved ends, mounting legs, loops, or other customized end structures where supported by the tooling configuration.
7. Cutting and Discharge
After forming is completed, the component is cut and discharged for inspection or subsequent heat treatment and surface processing.
Combining these operations in one programmed cycle helps reduce manual transfer between separate machines.
Why Agricultural Tine Springs Require Specialized Forming Equipment
Agricultural tine springs are more difficult to manufacture than standard round compression springs because they often combine coiling and long-wire forming in one component.
Important production challenges include:
Maintaining consistent coil diameter
Controlling the number and direction of coils
Producing equal or specified arm lengths
Maintaining accurate bend angles
Controlling springback after forming
Preventing long-arm deformation
Keeping left-hand and right-hand products symmetrical
Maintaining consistent mounting-end geometry
Processing high-strength spring wire
Achieving stable repeatability during batch production
A dedicated tine carrier spring machine coordinates these operations through programmable motion control, helping manufacturers improve consistency and reduce repeated manual adjustment.
