Series JY straightening machine is mainly used for precision straightening for the metal bar after peeling or grinding and pre-straightening for the metal bar. The machine adopted special curve between upper concave and the lower convex two straightening rolls to realize calendering and straightening at the same time,which greatly improved the working efficiency. Our technology reaches the domestic advanced level in reliability and quality while keeps a relatively lower price, with its efficiency more several times than the conventional process.
Our products are suitable to process different kinds of metal material, for instance, black metal material such as structural steel, alloy steel, spring steel, bearing steel,tool steel, copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, titanium and titanium alloy and other non-ferrous metal materials.
Note:① The hardness of raw materials should be uniform,the difference of HB hardness values in the same bar material ≤ 20 (difference of HRC hardness values ≤ 2).Raw material straightness shall meet the standards required by this agreement, otherwise automatic feeding cannot be realized. The head and tail must be chamfered before the raw material is straightened. When raw material is titanium alloy, it needs heating straightening.
Note:②Due to the difference in material properties, the finished products are about 260 mm, and the straightness of bright bar is about 0.50mm/m.The diameter tolerance of bar material with a certain length at each end of bright bar varied obviously, and the tolerance variation at the end was about ±0.4mm. Finished the difference in size with the rest of the team: Φ10~30:≤0.03mm,Φ30~40:≤0.04mm.
