Tine Carrier Spring Making Machine | CNC Agricultural Tine Spring Manufacturing Solution

July 31 2026

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.


Manufacturable Products

The Tine Carrier Spring Making Machine can be configured to produce different agricultural spring components according to customer drawings and wire specifications.

Typical manufacturable products include:

  • Tedder Tine Springs

  • Rotary Rake Tine Springs

  • Baler Pickup Tines

  • Hay Rake Spring Tines

  • Forage Machinery Tines

  • Harvester Pickup Tines

  • Cultivator Spring Tines

  • Agricultural Double Torsion Springs

  • Long-Arm Torsion Springs

  • Tine Carrier Springs

  • Crop Pickup Spring Fingers

  • Agricultural Return Springs

  • Farm Machinery Retaining Springs

  • Custom Bent Spring Tines

  • Special Agricultural Wire Forms

Actual production capability depends on wire diameter, material strength, coil dimensions, arm length, bend geometry, end configuration, required tolerances, and target production speed.


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.
