High precision cold drawn pipe is made of seamless hot-rolled steel pipe

High precision cold drawn pipe is made of seamless hot-rolled steel pipe, straight seam welded pipe as blank, after chemical treatment on the special cold drawing machine, through the special deformation principle of design of mould drawing, produce high precision tube..Dinstinction between of production process of hydraulic cylinder and the traditional  Hydraulic cylinder body are main production high precision cold drawn tube was used as raw material, compared with the traditional production process, not only now the production of hydraulic cylinder China tail pulley Factory .

 Hydraulic cylinder body are main production high precision cold drawn tube was used as raw material, compared with the traditional production process, not only now the production of hydraulic cylinder speed, and save raw materials, high yield.2 high functions: due to the effect of rolling pressure head and the guide of the boring, in the process of cutting, the blank pipe due to the weight of the deflection, the rolling head deviate and boring cutter, cause waste. The dimensional accuracy of H10 ~ H8, straightness of 0.4, can improve the mechanical properties of the finished tube metal: production by drawing method, make blank gets more than 30% of the plastic deformation, due to work hardening has greatly improve the strength of the finished tube metal limit.6-0.Generally in the finished tube layer strength limit increase of 60%.

Below to specific introduction of cold drawn pipe production process of hydraulic cylinder and the traditional distinction:1, high efficiency: with the traditional method of producing a diameter of 420 mm, 12 meters long cylinder should be 154 hours, with the method of cold drawing production only 4 minutes. When using a method of drawing production, metal not only by cutting the end of the iron, it can get 30% extension of metal utilization rate can reach 95%. Functions only around 60%, and with cold drawn method production, functions can reach more than 95%.The hydraulic cylinder of cold drawn pipe productionThe hydraulic cylinder of cold drawn pipe production3, high utilization rate of metal: made of traditional method of boring cylinder body, metal utilization only 50-70%..We have pipe inventory of these pipe,pls contact us if you need
