Description
Technical field
The utility model relates to a kind of screw rod, specifically relates to a kind of screw for extruder.
Background technology
Extruder screw is the most important parts of extruder equipment, it is directly connected to range of application and the production efficiency of extruder, screw rod is generally made up of the steel alloy of high-strength corrosion-resisting, Chinese utility model patent (application number 201220534471.7) provides a kind of extruder screw of Split type structure, screw-rod structure die orifice end starts to be divided into die orifice section successively, homogenizing zone, transportation section, compression section, extruded segment, feeding section, adopt screw rod to connect between every section or adopt key to connect or adopt and be welded to connect, but when the thread damage of any one section of screw surface or when needing to change, this section of screw-rod structure entirety is all needed to change, waste to a certain degree can be caused so undoubtedly.
Utility model content
For solving the above-mentioned problem points that has or shortcoming, the utility model provides a kind of Novel extrusion machine screw rod, and this Novel extrusion machine screw rod can reduce production cost, and manufacturing process is easy, and screw thread sheet and screw rod are absolute construction, is convenient to change.
To achieve these goals, the utility model extruder screw realizes by following technical scheme:
This Novel extrusion machine screw rod, comprise screw body, it is characterized in that: described screw body is umbrella integral structure, head is conical, end is provided with screw thread and nut, surface is provided with strip groove, described screw body is also provided with the separate threads sheet with described groove fit, and described separate threads sheet and nut closely cooperate.
Further, described groove has one at least, and bottom is rectangle.
Further, described groove and described separate threads sheet are matched in clearance.
The beneficial effects of the utility model are: this Novel extrusion machine screw rod not only transmitting torque is large, and when thread damage, can only change separate threads sheet, screw body is without integral replacing, reduce production cost, greatly reduce material waste, facilitate production operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the screw body schematic diagram after unloading separate threads sheet;
Fig. 2 is the schematic diagram of Novel extrusion machine screw rod;
Fig. 3 is the screw body sectional view after unloading separate threads sheet;
Fig. 4 is the sectional view of Novel extrusion machine screw rod.
Wherein Reference numeral is expressed as: 1-screw body, 2-nut, 3-groove, 4-separate threads sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate the utility model screw for extruder.
The screw body unloaded after separate threads sheet as shown in Figure 1, screw body 1 is in umbrella integral structure, and head is conical, and end is provided with screw thread and nut 2, and surface is provided with strip groove 3;
Fig. 2 is the schematic diagram of Novel extrusion machine screw rod, and separate threads sheet 4 is contained in the groove 3 of screw body 1, closely cooperates with the nut 2 of rear end;
See the sectional view of Fig. 3 Novel extrusion machine screw rod, groove 3 and separate threads sheet 4 are matched in clearance;
Unload the screw body sectional view after separate threads sheet see Fig. 4, groove 3 has one at least, and bottom is rectangle.
Above embodiment, only in order to the technical solution of the utility model to be described, can not limit scope of the present utility model with this; To the amendment that the technical scheme described in foregoing embodiments is carried out, or to the equivalent replacement that wherein portion of techniques feature is carried out, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model, all should still belong in scope that the utility model patent contains.
