Description
Technical field
The utility model relates to a kind of assembled screw rod.
Background technology
Screw rod is the critical component of comminutor the inside, and comminutor screw rod commonly used is monolithic construction.Screw rod is as main part, because the degree of wear of the each several part of screw rod is different, lacks spare part after the part wearing and tearing, can only gather together and use, and is by the time tangible unrenewable, just change, but wearing and tearing screw rod afterwards can reduce the extrusion efficiency of comminutor.Therefore in the urgent need to improving screw-rod structure, reduce manufacture difficulty, reduce the manufacturing cost of existing screw rod, and then reduce the replacement cost of screw rod.
The utility model content
For the problems referred to above, the utility model provides a kind of manufacture difficulty that reduces screw rod, the assembled screw rod structure that the each several part of screw rod removably connects.
for achieving the above object, the utility model assembled screw rod, comprise axle journal and be connected the axle core that axle journal connects, be set in successively the feeding section on described axle core, the compression melt zone, homogenizing zone and retaining mechanism, wherein said feeding section, described compression melt zone be connected the dismountable connection of homogenizing zone, wherein said feeding section and described axle core are structure as a whole, described axle core is provided with external splines, described compression melt zone and described homogenizing zone are middle hollow nested structure, be equipped with the internal spline suitable with described external splines in it, the end of described axle core is provided with screw thread, described retaining mechanism comprises spring, pressure ring, gland and and described axle core on the suitable nut of screw thread, wherein said spring and described pressure ring are set on described axle core successively, described gland is bolted on and compresses described pressure ring and described spring on nut.
Preferably, the tightening direction of described nut is identical with turning to of described screw rod.
Further, the screw thread of described feeding section is the structure of uniform pitch deep thread, and the screw thread of described compression section is the structure that the dark pitch such as helicla flute diminishes gradually, and the screw thread of described homogenizing zone is that the helicla flute pitch that shoals becomes large structure.
1, the utility model assembled screw rod, by a screw rod is adopted fabricated structure, to compress melt zone, homogenizing zone and feeding section and distinguish manufacturing, make dismountable structure, wherein feeding section in use weares and teares very slowly, makes an integral body with axle journal and mandrel, homogenizing zone is the fastest part of wearing and tearing, homogenizing zone has worn and torn, and can take off from whole axle, realizes quick-replaceable.
2, the utility model assembled screw rod has reduced the whole manufacture difficulty of screw rod, and the cost with less has improved productivity effect, and effectively reduces equipment maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model assembled screw rod;
Fig. 2 is the structural representation of the external splines of the utility model assembled screw rod;
Fig. 3 is the structural representation of the suitable internal spline of external splines in the utility model assembled screw rod Fig. 2;
Fig. 4 is that the tight latch mechanism of the utility model assembled screw rod compresses the screw rod each several part structural representation that is integrated.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
as shown in Fig. 1-4, the utility model assembled screw rod, comprise axle journal 21 and be connected the axle core 2 that axle journal connects, be set in successively the feeding section 22 on described axle core, compression melt zone 23, homogenizing zone 24 and retaining mechanism 26, wherein said feeding section, described compression melt zone be connected the dismountable connection of homogenizing zone, wherein said feeding section and described axle core are structure as a whole, described axle core is provided with external splines 11, described compression melt zone and described homogenizing zone are middle hollow nested structure, be equipped with the internal spline 12 suitable with described external splines in it, the end of described axle core is provided with screw thread, described retaining mechanism comprises spring 63, pressure ring 64, gland 66 and and described axle core on the suitable nut 65 of screw thread, wherein said spring and described pressure ring are set on described axle core successively, described gland is fixed on by bolt 67 and compresses described pressure ring and described spring on nut.
As shown in Figure 4, there is screw thread mandrel 2 ends, tighten by nut 65, push down pressure ring 64, and pressing spring 63 again, then push down the homogenizing zone 25 of screw rod, and feeding section, compression melt zone, homogenizing zone with mandrel are become one.The effect of gland 66 is to prevent that plastics from entering axle sleeve, is fixed on nut 65 by bolt 67.The tightening direction of the nut 65 of described axle core end is identical with turning to of screw rod, can be due to the rotation of screw rod since so, and make nut be unlikely to occur loosening.
Because feeding section in use weares and teares very slow, axle journal and mandrel make an integral body, compression melt zone and homogenizing zone are made nested structure, be in the same place with the feeding section string, adopt spline joint, the centering mode of splined adopts internal diameter centering, although processing is convenient not as diameter centering, centering precision is high.The screw thread of described feeding section is the structure of uniform pitch deep thread, improves compression ratio; The screw thread of described compression section is the structure that the dark pitch such as helicla flute diminishes gradually, the screw thread of described homogenizing zone is that the helicla flute pitch that shoals becomes large structure, and plastics are extruded fast, reduces plastics in the time of staying of homogenizing zone, raise the efficiency, reduce the probability that degraded occurs plastics.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
