Abstract
The utility model discloses a novel combined screw and belongs to the technical field of improvement of screws. The novel combined screw comprises a main rod, a thread piece, an end socket cap, a thread groove, a tip piece and a screw hole; the main rod is provided with the thread groove; the thread piece is screwed into the main rod through the thread groove; one end of the main rod is provided with the tip piece; the tip piece is provided with a thread; the end socket cap is provided with the screw hole; and the end socket cap is screwed into the tip piece through the screw hole. The screw comprises two large parts, namely the main rod and the thread piece; a structure of combining the two large parts is adopted; and due to the combined structure, when the thread is twisted and damaged or the main rod is worn, only the corresponding component is needed to be replaced, so that waste of materials is reduced.
Description
Technical field
The utility model relates to a kind of novel combination type screw rod, belongs to screw rod and improves technical field.
Background technology
Screw rod is the screw thread transmission campaign of utilization itself or the shaft-like machine components of power; Multiplex in plastic molding equipment, as plastic section extruding machine, injection machine etc.; Screw rod and machine barrel are the core components of plastic molding equipment; It is the part of heating extrusion plasticizing; It is the core of plastics machinery.
Screw rod is worked under high temperature, certain burn into strong wear, high pulling torque, and therefore, screw rod is necessary: 1) high temperature resistant, and indeformable under high temperature; 2) wear-resistant, the life-span is long; 3) corrosion-resistant, material has corrosivity; 4) high strength can be born high pulling torque, high rotating speed; 5) has good machinability; 6) after heat treatment, residual stress is little, and thermal deformation is little etc.
On market, the form of screw rod is various, and screw rod often can be damaged in running, after damage, will integral replacing, and can cause like this waste of material; Screw rod damages two kinds of the wearing and tearing of distortion damage that main forms is screw thread and mobile jib, no matter be any damage, the capital causes whole screw rod to be scrapped, so how could work as when wherein a kind of damage occurring, only need to change one of them parts, in order to reduce the waste of material, this is a problem that urgent need will solve.
Summary of the invention
How could to work as when wherein a kind of damages occurring in order solving, only to need to change one of them parts, so that the problem of minimizing waste of material; The utility model proposes a kind of novel combination type screw rod.
The technical scheme that the utility model adopts is:
A kind of novel combination type screw rod, comprise mobile jib, screw thread sheet, end-sealing cap, thread groove, termination part and screw, offer thread groove on mobile jib, the screw thread sheet screws in mobile jib by thread groove, mobile jib one end is provided with the termination part, the termination part is provided with screw thread, offers screw on end-sealing cap, and end-sealing cap screws in the termination part by screw.
Advantage of the present utility model: this screw rod is divided into mobile jib and the large parts of screw thread sheet two, two large component combination formula structures have been adopted, due to this fabricated structure, when the wearing and tearing of threaded distortion damage or mobile jib, only need to change corresponding parts, so just reduced the waste of material.
Description of drawings
Fig. 1 is a kind of schematic diagram of novel combination type screw rod;
Fig. 2 is the component diagram of mobile jib;
Fig. 3 is the cutaway view of end-sealing cap;
Fig. 4 is the stereogram of screw thread sheet;
In figure: 1, mobile jib 2, screw thread sheet 3, end-sealing cap 4, thread groove 5, termination part 6, screw.
The specific embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in the figure, a kind of novel combination type screw rod, comprise mobile jib 1, screw thread sheet 2, end-sealing cap 3, thread groove 4, termination part 5 and screw 6, offer thread groove 4 on mobile jib 1, screw thread sheet 2 screws in mobile jib 1 by thread groove 4, and mobile jib 1 one ends are provided with termination part 5, and termination part 5 is provided with screw thread, offer screw 6 on end-sealing cap 3, end-sealing cap 3 screws in termination part 5 by screw 6.
Mobile jib 1 and screw thread sheet 2 have formed the screw rod main body; As depicted in figs. 1 and 2, end-sealing cap 3 is that the openend for sealing thread groove 4 arranges, and can prevent effectively that like this screw thread sheet 2 from screwing out from mobile jib 1 at the volley; Thread groove 4 is passages that screw thread sheet 2 changes mobile jib 1 over to; Termination part 5 and screw 6 cooperatively interact, and make end-sealing cap 3 can be fixed on mobile jib 1.
Operation principle of the present utility model: this screw rod mainly will have screw rod now and manufacture mobile jib 1 and 2 liang of large parts of screw thread sheet, wherein screw thread sheet 2 screws in mobile jib 1 by the thread groove 4 on mobile jib 1, formed the core of screw rod, then screwed on the termination part 5 of mobile jib 1 by end-sealing cap 3; This screw rod is compared with common screw, mainly mutually combining by mobile jib 1 and 2 liang of large parts of screw thread sheet, it is a fabricated structure, such structure is in screw motion, in case damaging appears in one of them parts, only corresponding parts need to be taken off, replace with new parts and get final product, so just reduced the waste of material, realized its improved purpose.
