Product Description:

P11 alloy tube can be recycled 100%, in line with the national strategy of environmental protection and energy conservation, conservation of resources, the national policy to encourage the expansion of the application fields of P11 alloy high-pressure pipe.

P11 alloy steel pipe is placed in the metal blank cold extrusion die cavity, at room temperature, through the press fixed punch pressure is applied to the blank, processing method to produce plastic deformation of P11 alloy steel pipe made of parts.

[1] extruded P11 alloy steel pipe size accurate smooth surface: at present our country in the development of P11 alloy steel pipe generally size precision can reach 8 ~ 9

Level, long degrees generally reach, if the lubrication can reach by ideal (refers to pure aluminum and copper parts), second only to the polishing surface. Therefore made of P11 alloy steel pipe method of parts, generally do not need to re processing, a small amount of just finishing (grinding).

[2] to save raw materials: P11 alloy steel material utilization rate is usually can reach more than 80%. Such as Jiefang automobile piston pin dynamic cutting material utilization rate is 43.3%, while the use of cold extrusion material utilization rate increased to 92%; and as the universal joint bearing sleeve to cold extrusion, the material utilization rate increased from 27.8% to 64% in the past. Visible, by cold extrusion method for producing machine parts, and can save a lot of steel and non-ferrous metal materials.

[3] high productivity: the efficiency of extrusion production machinery parts P11 alloy steel pipe by the method of cold is very high, especially the mass production of parts with cold extrusion steel tube production method, P11 alloy than cutting increased several times, dozens of times, even hundreds of times. For example, automobile piston pin cold extrusion method for manufacturing improved 3.2 times than by cutting, with current and piston pin cold extrusion automata, to further improve productivity. The productivity of a cold extrusion automata productivity is equivalent to 100 ordinary lathe or 10 sets of four spindle automatic lathe.

[4] can process the complex shape parts: such as profiled, inner gear, profiled hole and blind hole, the P11 alloy steel pipe is used in other processing method is difficult to finish, with cold extrusion processing is very convenient. As shown in the parts, convenient extrusion.

[5] the cold extrusion of P11 alloy steel high strength, good rigidity and light weight: because the cold extrusion adopts metal material cold deformation hardening of cold extrusion characteristics, namely the metal blank in three to the compressive stress state, the deformed materials, and has dense microstructure fiber flow continuous, so the parts strength greatly to improve the. So that it can use low strength material instead of high strength materials. For example, in the past 20Cr steel by machining manufacturing Jiefang piston pin, now changed to 20 steel by manufacturing piston pin cold extrusion, the determination of the indexes of performance, higher than the machining method of manufacturing piston pin cold extrusion of P11 alloy steel tube method.


Comparison of various processing methods, has outstanding advantages in cold extrusion of P11 alloy steel pipe technology and project. It is cold extrusion machining, forging, instead of casting and drawing process to produce machine parts, has opened up a broad road.
