Rectangular Spring Wire

Alternatively you can also produce lighter and smaller springs with comparable spring loadings as round wire.

Rectangular spring wire.

By using square or rectangular wires you can achieve springs that are stronger than traditional round wires and yet feature the same product properties and design. Spring shapes include oval rectangular oval square triangular. Astm a 231 astm a 401 die springs. For some applications where the cold winding could produce cracking during forming square rectangular wire springs are formed in the annealed condition and then heat treated.

Manufactured to tight tolerances and stringent quality control standards. Wire that is too hard cannot be formed and is unusable for producing formed helical springs. Either chrome vanadium astm a 231 or chrome silicon astm a 401. Design of a cold coiled helical spring made from rectangular section wire subjected to a static or infrequently varying load.

All parts are made of alloy spring steel. The general comments on round wire torsion springs apply to springs with rectangular wire. A compression spring is required to meet a load f 1 530 n at l 1 55 mm and f 2 1 060 n at ls 45 mm. Specializing in fine diameter non standard cross section and specialty material wire.

B 1 b c 0 5 c when axial length is critical keystone shaped wire can be purchased. Materials include 302 304 316 17 7 stainless steel music wire tin zinc galvanized music wire phosphor bronze beryllium copper brass hard drawn mb galvanized hard drawn oil tempered. Springs made from rectangular wire with the width of the rectangle perpendicular to the spring axis store more energy in a smaller space than equivalent round wire springs. Rectangular springs range in wire sizes from 005 in.

All parts are painted white with ends dipped for color coding. A rectangular spring is a compression spring that is formed in an oval shape as opposed to a cylindrical shape as most compression springs are. The space available permits a maximum outside dia d o i d m of 25 5 mm and a rod of 14 mm should pass freely inside the spring in fitment. Even though stress distribution around the rectangular cross section is not as uniform as the round wire section the energy storage capacity is higher because more.

In producing springs from rectangular wire the wire cross section distorts and becomes keystoned the wire axial dimension b1 can be estimated from. Manufactured from rectangular shaped wire diamond die springs meet stringent quality standards throughout production from start to finish.
