Embodiment
- Fig. 4 is please referred to Fig.1, a kind of face-hardened large thin-wall stainless steel axle sleeve manufacture work is present embodiments provided Skill, wherein the outer diameter of large thin-wall is 500mm-800mm, and the wall thickness of large thin-wall is 1.5mm-8mm.The manufacturing process packet It includes:
Step S1, the internal perisporium and periphery wall of the relatively thin rough forging part 100 of the hollow wall of rough turning,
Step S2, the internal perisporium of rough forging part 100 described in finish turning, and internal perisporium is there are the process of surplus,
Step S3, the rough forging part 100 is set in outside anti-deformation tool 200, the rough forging part 100 and institute The interference fit of anti-deformation tool 200 is stated,
Step S4, surface hardening processing is carried out to the periphery wall of rough forging part 100,
Step S5, the anti-deformation tool 200 is taken out from the rough forging part 100,
Step S6, thick, rough forging part 100 described in finish turning internal perisporium, Cutting parameters when finish turning are:Linear velocity V=(20m~50m)/min, amount of feeding L=(0.1mm-0.4mm)/r, chip depth h=0.20mm~25mm.
Step S7, axle sleeve 400 is set in outside large ventilator main shaft 300, the periphery wall of axle sleeve 400 described in finish turning.
Face-hardened large thin-wall stainless steel axle sleeve manufacturing process provided in this embodiment, when turning, first rough turning forging The periphery wall of blank 100, then the internal perisporium of turning rough forging part 100 are made, by internal perisporium turning to setting value.Due to forging The diameter of the periphery wall of blank 100 is comparatively bigger, and wall thickness is relatively thin, and the surplus that periphery wall is reserved is seldom, such as Fruit directly carries out surface hardening to the periphery wall of rough forging part 100, it will causes the outer circle of axle sleeve to deform big, in following process During can not guarantee size requirement.Therefore, outer circle deflection is controlled using the fixed mode of tooling in present treatment technique It within the scope of one of very little, is plugged in rough forging part using anti-deformation tool 200, anti-deformation tool 200 and forging hair Blank 100 is interference fit, and such positioning method is simple and reliable, controls outer circle deflection.After surface hardening, it will preapre for an unfavorable turn of events Shape tooling 200 is taken out from rough forging part 100, then, thick, finish turning rough forging part 100 internal perisporium, due to forging hair The diameter of the periphery wall of blank 100 is comparatively bigger, and wall thickness is relatively thin (under normal circumstances in 2mm-8mm), and periphery The reserved surplus of wall is seldom, by the way that the technical clamp position of rough forging part 100 is clamped, rationally controls cutting parameter, both ensure that interior Circle quality, and control outer circle deflection.Finally axle sleeve 400 is set in outside the main shaft 300 of ventilation blower, then to axle sleeve 400 Periphery wall carries out finish turning, and also completing axle sleeve when completing the processing of axle sleeve is sleeved on ventilation blower main shaft, entire construction technology It is convenient reliable, it is at low cost.
During carrying out surface hardening to the periphery wall of rough forging part 100, in order to ensure that rough forging part 100 is not easy Deformation, and simplify clamp structure, anti-deformation tool 200 is plugged in rough forging part 100.Optionally, anti-deformation tool 200 Including cylinder, the outer diameter of cylinder section shape is more than the diameter of the cross sectional shape of the internal perisporium of rough forging part 100, i.e., round Cylinder is with rough forging part 100 in interference fit.
Further, there are two end faces, i.e. first end face and second end face along its axis direction tool for cylinder, in first end It is respectively arranged with chamfering in face and second end face, convenient for cylinder to be plugged in rough forging part 100.In actual job process In, after the periphery wall of rough forging part 100 is carried out surface hardening, need anti-deformation tool 200 from rough forging part 100 It takes out, optionally, the axis direction using the thrust of forcing press by anti-deformation tool 200 along rough forging part 100 is released, operation It is convenient reliable.Further, it is provided with limiting slot on at least end face of the first end face of cylinder and second end face, be convenient for The catch bar of forcing press is plugged in limiting slot, is not easy to skid.
It is optional in the present embodiment, when carrying out the internal perisporium of rough turning rough forging part 100, rough forging part 100 Periphery wall deflection is not more than 1mm.When carrying out rough turning, the processing capacity of internal perisporium is larger, in internal perisporium process, wall Thickness is gradually reduced, since periphery wall needs progress turning that can reach requirement, when periphery wall deflection is not more than 1mm, outside The allowance of peripheral wall is larger, easy to process.
Further, when the internal perisporium of half finish turning rough forging part 100, the periphery wall deflection of rough forging part 100 No more than 0.5mm, finally in the internal perisporium of finish turning rough forging part 100, suitable cutting output is selected so that outside turning Periphery wall has enough allowance when peripheral wall.
It should be noted that since rough forging part 100 is in substantially hollow cylindrical shape, undressed to setup parameter When (when undressed formation axle sleeve), the periphery wall of rough forging part 100 becomes without being in absolute cylindrical surface in control periphery wall It should ensure that each position of periphery wall is equal to be calculated at the allowance minimum position of rough forging part 100 when shape amount There is enough allowance.
In the present embodiment, optionally, in the internal perisporium of finish turning rough forging part 100, the periphery of rough forging part 100 Wall deflection is not more than 0.2mm.In turning, by the way of gradually turning, it is not easy to cause because disposable cutting output is excessive The problem of rough forging part 100 is scrapped.
In the present embodiment, axle sleeve 400 is set in outside the large ventilator main shaft 300 using hot-mounting process, it is then smart The periphery wall of axle set 400, makes periphery wall turning to setting value.After axle sleeve completion of processing, axle sleeve and ventilation blower are also completed The installation of main shaft 300, it is easy to use reliable.
Further, after completing installation of the axle sleeve with ventilation blower main shaft 300, the periphery wall for axle sleeve of polishing improves axle sleeve Surface smoothness.
It should be noted that when carrying out axle sleeve processing, in order to improve the processing quality of axle sleeve, finish turning rough forging part The Cutting parameters of 100 internal perisporium are:Linear velocity V=(20m~50m)/min, amount of feeding L=(0.1mm-0.4mm)/r, cuts Consider depth h=0.20mm~25mm to be worth doing.
It should be noted that the power of large ventilator is 1500w-15000w.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
