Straightening Roll for Multi-Station Cold Forming Machines

Straightening roll tooling for multi-station cold forming feed lines. Jungu checks wire diameter, groove radius, runout, bearing fit, surface wear, and feed stability before quoting.

What is Straightening Roll for Multi-Station Cold Forming Machines used for?

A straightening roll for multi-station cold forming machines controls wire straightness before cutting and heading. If the roll groove, runout, bearing fit, or surface condition is wrong, the wire enters the cut-off unit with bend, vibration, or surface damage. That error then appears later as blank length variation, off-center forming, or unexplained die wear. Jungu reviews the machine model, wire diameter range, groove profile, roll outside diameter, bearing seat, runout requirement, material route, surface finish, and photos of groove wear, wire scratches, feed vibration, or unstable cut length. This product is for buyers who need the feed line checked as part of cold-heading stability, not only a replacement roll by size.

Common sourcing use

Wire straightening before cold heading where groove profile, roll runout, and feed stability affect blank quality.

Technical Review Scope

What Jungu checks

  • Machine model, roll position, outside diameter, bearing seat, shaft fit, and runout requirement
  • Wire diameter range, material, surface condition, feed speed, and lubrication
  • Groove radius, surface hardness, coating or finish route, and roll pair alignment
  • Failure mode: wire scratch, feed vibration, bend memory, blank length drift, or uneven groove wear

Why no standard price is shown

This is B2B custom tooling. A reliable quotation depends on drawing, material, size, tolerance, machine setup, annual quantity, and the mould-life issue the buyer wants to solve. Jungu quotes after technical review instead of showing a misleading fixed price.

FAQ

Can roll wear affect heading die life?

Yes. Bent or scratched wire changes blank feeding and can create off-center load in later stations.

What measurement matters most?

Groove profile, bearing seat, and runout should be checked together; one correct dimension is not enough.

Can Jungu quote from the old roll?

A sample helps, but machine model, wire diameter, and runout requirement are still needed for a reliable route.

Can this product be customized?

Yes. Jungu manufactures fastener mould tooling according to buyer drawings, samples, and machine requirements.
