When damaging appears in this screw rod, people only need more smooth correspondence the damage section can, practiced thrift the replacement cost. Divide into a plurality of segments with whole screw rod for every little segment length of screw rod reduces greatly, preparation degree of difficulty greatly reduced, thus reduced the production cost of whole screw rod.
Description
Technical field
The utility model relates to screw technique field, is specifically related to a kind of Polypropylene compositions screw rod.
Background technology
Screw rod is that outside face has cut spiral fluted cylinder or cone, and screw rod can adopt different materials to make according to the difference used.Traditional screw rod uses that single material is one-body molded to be made usually, like this in concrete commercial production once the screw rod used is shaping, then the size of screw rod just secures, and cannot change.According to the difference of occupation mode, screw rod can be used for transmission, also can be used for transmitting or supercharging raw material.In the actual process used, traditional screw rod is owing to being one-body molded, and screw rod, once be damaged, even be the sub-fraction of screw rod, also must be carried out integral replacing, cause larger waste by screw rod.And rise the one-body molded processing of screw rod, must once successfully machine, and due to screw rod itself longer, easily occur waste product, difficulty of processing is comparatively large, and tooling cost is higher.In the process of processing, form fabrication stress to the one handling ease of screw rod to screw rod in addition, the fabrication stress of the more microscler one-tenth of screw rod is larger, and screw rod more easily damages in use.It is subject to the stressed of all directions to screw rod in use in addition, and the distance between screw rod is fixing, and so the brittle material of conveying easily smashes by screw rod, also makes screw rod itself easy to be squeezed bad.Polypropylene is a kind of thermoplastic base resin obtained by propylene polymerization.Polypropylene has good thermoplastic property, is easy to manufacture, and cost performance is higher.
Summary of the invention
For above problem, the utility model provides a kind of connection segment, the Polypropylene compositions screw rod mutually combined.
The utility model solves the technical scheme that its technical matters adopts: this Polypropylene compositions screw rod by metal side rod, plastic bar, that metal intermediate bar connects and composes an entirety is successively shaft-like; Described metal side rod, metal intermediate bar use metallic material to make, and described plastic bar is made by polypropylene, and the periphery of described metal side rod, plastic bar, metal intermediate bar is designed with interconnective helicallobe; Described metal side rod is assemblied in the two ends of overall screw rod, and described plastic bar, metal intermediate bar are assemblied in the centre of described two metal side rods; The external side end of described metal side rod is designed with the adapter shaft stretched out along axis, and the inner side of described metal side rod is designed with fitting recess; The two ends of described plastic bar are all designed with assembled shaft, and the two ends of described metal intermediate bar are all designed with fitting recess, and described plastic bar inserts described fitting recess by assembled shaft therebetween with described metal side rod, metal intermediate bar and is connected.
As preferably, described assembled shaft is designed with the banking stop perpendicular to described assembled shaft periphery; Described fitting recess is designed with the secondary groove inserting described banking stop.
As preferably, the number of described banking stop is two or more, is distributed in and states in described assembled shaft.
As preferably, the assembled shaft of described metal side rod, metal intermediate bar and described plastic bar is carried out position by the set pin run through and is fixed.
As preferably, the end of described assembled shaft is designed to spherical.
The beneficial effects of the utility model are: this Polypropylene compositions screw rod is connected with plastic bar by spaced Metallic rod, and when damaging appears in this screw rod, people only need more to slide corresponding damage section, have saved replacement cost.Described plastic bar uses polypropylene material to be made in addition, and be easy to manufacture, cost performance is higher.Whole screw rod is divided into multiple segment, and each segment length of screw rod is reduced greatly, and manufacture difficulty reduces greatly, thus reduces the cost of production of whole screw rod.The plastics section simultaneously increased in the middle of Metallic rod, makes whole screw rod can bear larger distortion, makes screw rod not easily squeezed broken, longer service life.

Fig. 1 is the structural representation in front after the assembling of this Polypropylene compositions screw rod.
Fig. 2 is the structural representation in plastic bar front.
Fig. 3 is the structural representation of metal intermediate bar side surface direction.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in Figure 1, Figure 2 with shown in embodiment in Fig. 3, this Polypropylene compositions screw rod, it by metal side rod 1, plastic bar 2, that metal intermediate bar 3 connects and composes an entirety is successively shaft-like; Described metal side rod 1, metal intermediate bar 3 use metallic material to make, and described metal side rod 1, metal intermediate bar 3 use aluminium to be made specifically.Described plastic bar 2 is made by polypropylene, and the periphery of described metal side rod 1, plastic bar 2, metal intermediate bar 3 is designed with interconnective helicallobe; It is characterized in that: described metal side rod 1 is assemblied in the two ends of overall screw rod, described plastic bar 2, metal intermediate bar 3 are assemblied in the centre of described two metal side rods 1; The external side end of described metal side rod 1 is designed with the adapter shaft 11 stretched out along axis, and the inner side of described metal side rod 1 is designed with fitting recess 4; The two ends of described plastic bar 2 are all designed with assembled shaft 21, and the two ends of described metal intermediate bar 3 are all designed with fitting recess 4, and described plastic bar 2 and described metal side rod 1, metal intermediate bar 3 insert described fitting recess 4 by assembled shaft 21 therebetween and be connected.Screw rod shown in this embodiment is mainly used in during plastic working unloads, and is mainly used to carry granular plastics.Wherein said adapter shaft 11 is used for being connected with the drive mechanism of equipment, and whole screw rod utilizes blade to carry material when rotated.
This Polypropylene compositions screw rod is connected with plastic bar by spaced Metallic rod, and when damaging appears in this screw rod, people only need more to slide corresponding damage section, have saved replacement cost.Described plastic bar uses polypropylene material to be made in addition, and be easy to manufacture, cost performance is higher.Whole screw rod is divided into multiple segment, and each segment length of screw rod is reduced greatly, and manufacture difficulty reduces greatly, thus reduces the cost of production of whole screw rod.The plastics section simultaneously increased in the middle of Metallic rod, makes whole screw rod can bear larger distortion, makes screw rod not easily squeezed broken, longer service life.
