Preferably, in the above-mentioned extrusion axis, said supportive body is the main body of 4Cr5MoSiV1 material or the main body of 5CrNiMo material.
Preferably, in the above-mentioned extrusion axis, said working end is connected through bolt with said supportive body.
Preferably, in the above-mentioned extrusion axis, said bolt is 3, and circumferentially evenly distributing along said working end.
Preferably, in the above-mentioned extrusion axis, also comprise being used for the positioner that said working end is connected with said supportive body.
Preferably, in the above-mentioned extrusion axis, a said working end end relative with said supportive body is provided with boss, and the end that said supportive body is relative with said working end is provided with the groove that cooperates with said boss.
Preferably, in the above-mentioned extrusion axis, said boss is arranged on the outer surface of said working end, and said groove is arranged on the outer surface of said supportive body.
A kind of extruder comprises extrusion axis, and wherein, said extrusion axis is above-mentioned each described extrusion axis.
Can find out from above-mentioned technical scheme, the invention provides a kind of extrusion axis, comprise supportive body and the working end that is arranged on the supportive body end, wherein, the material of this working end is 4Cr5MoSiV1.Because the mechanical performance of 4Cr5MoSiV1 and mechanical performance and the mechanical property that mechanical property is far longer than 5CrNiMo; Therefore; When the working end of this extrusion axis contacts with the extruding pad, can prevent the working end distortion, effectively improved the impact strength of this extrusion axis; Thereby improved its service life, reduced production cost.
The invention also discloses a kind of extruder, this extruder comprises extrusion axis, and this extrusion axis is above-mentioned each disclosed extrusion axis.Because extrusion axis has above-mentioned technique effect, therefore, the extruder with this extrusion axis also has identical technique effect.
Description of drawings
The structural representation of the extrusion axis that Fig. 1 provides for the embodiment of the invention.
The specific embodiment
A core of the present invention provides a kind of extrusion axis of new structure, with hardness and the intensity that improves its work termination, thereby improves its service life.Another core of the present invention provides a kind of extruder with this extrusion axis.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and embodiment.
Please refer to Fig. 1, the invention discloses a kind of extrusion axis, comprise supportive body 11 and the working end 12 that is arranged on supportive body 11 ends, wherein, the material of working end 12 is 4Cr5MoSiV1.
Because the mechanical performance of 4Cr5MoSiV1 and mechanical performance and the mechanical property that mechanical property is far longer than 5CrNiMo; Therefore; When the working end 12 of this extrusion axis contacts with the extruding pad, can prevent working end 12 distortion, effectively improved the impact strength of this extrusion axis; Thereby improved its service life, reduced production cost.Use the 4Cr5MoSiV1 of 1040 ℃ of vacuum hardenings, 590 ℃ and 570 ℃ tempering in the present embodiment.
Among the concrete embodiment, the internal diameter of working end 12 is identical with the internal diameter of supportive body 11, and the external diameter of working end 12 is identical with the external diameter of supportive body 11 links, to guarantee the intensity of whole extrusion axis.During installation, need to guarantee both axialities.
In order to reduce production cost, the material of the supportive body 11 of extrusion axis is set to 5CrNiMo in the present embodiment.In actual production can according to different needs also can supportive body 11 material be set to 4Cr5MoSiV1, promptly be set to identical material with the material of working end 12.
Further among the embodiment, working end 12 is connected through bolt 3 with supportive body 11, i.e. working end 12 and 11 dismountable connections of supportive body.Can make after 12 distortion of working end through above-mentioned setting, only need to change working end 12 and get final product, and keep supportive body 11, promptly reduce the parts of changing, therefore reduce production cost.
In the preferred embodiment, in order to guarantee connection stability, the number of bolt 3 is set to 3, and along the working end 12 circumferentially evenly distribute.
