Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, referring to Fig. 1-2 8:
The manufacture method of Roots air blower comprises: according to the geomery of Roots air blower section, make a blanking die, blanking die becomes impeller thin slice 1 sheet metal forming and goes out axis hole 8 and positioning hole 3, and that also can wash away weight reduction goes to expect position 7, in the described impeller thin slice that goes material to be included in large specification, rush the impeller thin slice of small dimension, the impeller thin slice of this large specification only has positioning hole 3 there is no axis hole, good impeller thin slice 1 closed assembly of stamping-out, closed assembly can not be equipped with at two ends and be no less than the impeller thin slice that a slice has axis hole while there is no the impeller thin slice of axis hole, also can in interleave and be no less than the impeller thin slice 1 that a slice has axis hole, between be inserted in the impeller thin slice that has axis hole not having in the impeller of axis hole thin slice can be thicker than there is no the impeller thin slice of axis hole, or be inserted in the impeller thin slice that has axis hole not having in the impeller of axis hole thin slice and be welded into one with the impeller thin slice point that has axis hole of several same thickness.The in-built connecting rod 4 of positioning hole 3 of impeller thin slice, connecting rod 4 two ends and impeller thin slice 1 weld together becomes impeller; If impeller thin slice 1 thickness is too thin or welding difficulty, the impeller end plate 2 clamping impeller thin slices 1 thicker than impeller thin slice can be respectively set at the two ends of the good impeller thin slice of closed assembly; Positioning hole 3 each positioning hole relative with impeller end plate 2 of impeller thin slice 1 is equipped with respectively connecting rod 4, and connecting rod 4 two ends and impeller end plate 2 weld together becomes impeller.
The processing method of described impeller end plate 2 comprises selects steel plate fine-punching formation, optional 3-10 millimeters of the thickness of steel plate, the concrete thickness of impeller end plate 2 can determine according to impeller size, the impeller two ends impeller end plate 2 that impeller diameter is large can be thicker, and the impeller two ends impeller end plate 2 that impeller diameter is little can be thinner.As 4-6 millimeters of the impeller end plate thickness of 100-180 millimeters of rotor diameters, it is 5-7 proper that connecting rod diameter is got.Described connecting rod 4 and the optional transition fit of positioning hole 3 of impeller thin slice 1, connecting rod 4 can be set according to impeller size with the quantity of positioning hole 3.The profile of impeller end plate 2 and positioning hole 3, axis hole 8 also can stamping-out moulding, and what impeller end plate 2 can not wash away weight reduction goes to expect position; Between the positioning hole 3 of impeller end plate 2 and connecting rod 4, have larger gap, the positioning hole 3 of impeller end plate 2 and the gap of connecting rod 4 also can be welded to each other part between impeller end plate 2 and adjacent impeller thin slice 1 when welding is filled up; In actual welding process, impeller end plate 2 positions, hole are filled up in the soldered electric current scorification of connecting rod 4 voluntarily, make connecting rod two ends become large, be greater than the position that impeller thin slice 1 coordinates, play the effect of pinning impeller thin slice 1, connecting rod 4 two ends can be welded together with impeller end plate 2 well, the good integrity of impeller.
The manufacture method of Roots air blower also comprises, described clip connection device is: the local punching press of impeller thin slice 1 is protruded and become clasp 6, clasp 6 enters another sheet impeller thin slice 1 and washes away in the depression that clasp stays, clasp 6 makes adjacent impeller thin slice 1 and the mutual snapping of impeller thin slice 1, and the clasp 6 of protrusion can be removed clasp with the surface of contact of impeller end plate 2; Described clasp 6 comprises is arranged to bridge shape, cylindrical and monolateral shape, and impeller thin slice 1 and the mutual snapping method of impeller thin slice 1, comprise the progressive die that self-feeding is set, and stamping-out can complete automatically with mutual snapping operation.Described cylindrical clasp, be included on impeller thin slice 1 and go out circular hole, in the process of punching, the columniform clasp of going out is only flushed to half of sheet thickness, that is to say that the material of going out only shifts out half of sheet thickness, enter another sheet impeller thin slice 1 and wash away in the hole that clasp stays.
The manufacture method of Roots air blower also comprises: described closed assembly becomes the axis hole 8 of impeller to mix fan shaft 9 becomes band fan impeller axle, fan shaft 9 can be arranged to stepped shaft, impeller is mixed in the large end of fan shaft 9 and the step of small end location, the small end of fan shaft 9 arranges outside thread near the position of impeller, with swivel nut 10, impeller is compressed, connecting rod 4 and two end plates are welded and fixed and become band fan impeller axle, in the process of processing belt fan impeller axle the welding scar at impeller two ends, the cylindrical of the plane of impeller end plate 2 and swivel nut 10, length is worked into required size together becomes rotor 43, can guarantee that rotor 43 has good parallelism, conventionally with grinding bearing position after machined into, the impeller working surface of stamping-out is cutting again.
Described fan shaft 9 is arranged to stepped shaft, impeller is mixed in the large end of fan shaft 9 and the step of small end location, the small end of fan shaft 9 arranges outside thread near the position of impeller, available hold-down mechanism is with swivel nut 10, impeller middle part being compressed after the relative compacting of impeller thin slice 1 of impeller end plate 2 clampings, impeller periphery is welded and fixed by connecting rod 4 and impeller end plate 2, under the operating mode that welding is also compacted at impeller, carry out, become whole band fan impeller axle, in the process of processing belt fan impeller axle the welding scar at impeller two ends, the cylindrical of the end face of impeller end plate 2 and swivel nut 10 is worked into required size together.In actual welding process, the positioning hole 3 of impeller end plate 2 is filled up in the soldered electric current scorification of connecting rod 4 meeting voluntarily, after melt solidifying, make connecting rod 4 two ends be greater than the position that impeller thin slice 1 coordinates, play the effect of pinning impeller thin slice 1, connecting rod 4 two ends can be welded together with impeller end plate 2 well, the good integrity of impeller.Mix after described stepped shaft fan shaft, flat key, spline and swivel nut 10 compress and become band fan impeller axle, integrity is better; In the process of processing belt fan impeller axle, the end face of the welding scar at impeller two ends and impeller end plate 2 and swivel nut 10 are worked into required size together, after the welding scar at turning two ends and the end face of impeller end plate 2 also need not but the integrity of heart band fan impeller axle.The labyrinth seal groove 49 of the cylindrical setting of the step-like large end of fan shaft and swivel nut 10 is also worked into required size together becomes the rotor 43 that can be used for assembling Roots blower.
