Spring Production Process
In general
The spring forming process is divided into cold winding and hot winding, one is directly wound with cold wire, and one is to heat the wire until red soft then wind it, and then cool it. Cold winding is generally adapted to the small wire less than 16 mm. Hot winding is adapted to larger wire diameter. Here are some basic procedures:
Spring Material Preparation
First of all, we have to determine the selected materials according to the technical requirements of the spring, such as carbon steel wire, piano wire, alloy steel wire, stainless steel wire, copper wire …… and we have to check the surface of the wire for rust, scars, etc.
Debug Equipment
Use different types of spring machines according to the diameter of the wire.
The corresponding ground wire wheel, wire groove, curve gauge, pitch pusher, mandrel, cutter, etc. are resharpened and installed on the machine. Then put the selected wire and start debugging. Confirm that there is no error before starting production.
Surface Treatment
Including grinding head, standing treatment, surface treatment (plating, painting, oxidation, etc.), and so on, which are according to the customer’s requirements
Spring Inspection
In accordance with the requirements of the drawings, including surface scars, rust and corrosion … force value, strength has reached the requirements, the spring and tightening height, fatigue life, etc.
Package
Packaging according to customer requirements, using cartons, wooden pallets, etc.
