Description
Technical field
The present invention relates to mechanical fitting field, more precisely extruder screw bimetallic thread bush.
Background technology
Bimetallic thread bush is the part of extruder or other equipment screw rods, and then screw rod is overlapped thread bush and combine on mandrel by mandrel.Existing bimetallic thread bush is that same metal adopts monoblock cast, on it, threaded portion is owing to adopting same material metal, domestic general employing 38CrMoALA high-quality nitrated steel material, and the thread bush of this structure is in use because the stressed effect in threaded portion greatly easily produces fracture, reduce the service life of screw rod, and adopted external steel, rapid-result tool steel material W6Mo5Cr4V2 (6542) of the height as Germany, its price is high, adds cost of manufacture.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of extruder screw bimetallic thread bush, solves the problem of thread bush fracture, add service life, provide cost savings, save 3 times than originally, performance adds original 1.5 times.
Extruder screw bimetallic thread bush, comprise base portion and screw thread, also comprise groove and the rapid-result tool steel of height, base portion center is provided with through hole, for installing screw rod bar core, described base portion arranges screw thread, this screw thread is provided with groove, be welded with high rapid-result tool steel in the edge of described groove, avoid the problem that thread bush ruptures.
As preferred embodiment of the present invention, described base portion adopts 38CrMoALA high-quality nitrated steel.
As preferred embodiment of the present invention, the inward flange of described through hole is provided with some bar-shaped troughs,
Be convenient to screw rod bar core pass through.
Therefore the advantage of extruder screw bimetallic thread bush of the present invention is, solve the problem of thread bush fracture, add service life, provide cost savings, save 3 times than originally, performance adds original 1.5 times.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention;
Wherein:
1, base portion; 2, screw thread; 3, groove; 4, high rapid-result tool steel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of extruder screw bimetallic thread bush, solve the problem of thread bush fracture, add service life, provide cost savings, save 3 times than originally, performance adds original 1.5 times.
As shown in Figure 1, extruder screw bimetallic thread bush, comprises base portion 1 and screw thread 2, also comprise groove 3 and the rapid-result tool steel 4 of height, base portion 1 center is provided with through hole, for connecting firmly mutually with screw rod bar core, through hole edge is provided with bar-shaped trough, is convenient to the operation that screw rod bar core ribbon moves thread bush; Base portion 1 is provided with screw thread 2, screw thread 2 is provided with groove 3, the edge in groove 3 is welded with high rapid-result tool steel 4.
In the present embodiment, this base portion 1 adopts 38CrMoALA high-quality nitrated steel, avoids the damage of base portion, adds its service life.
The threaded portion fluting of thread bush of the present invention, then high rapid-result tool steel material is welded, the base portion of thread bush adopts the low-cost base material steel of domestic production, the common 38CrMoALA high-quality nitrated steel material of current use, which solve the problem of thread bush fracture, add service life, provide cost savings, save 3 times than originally, performance adds original 1.5 times.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
Claims (3)
1. extruder screw bimetallic thread bush, comprise base portion (1) and screw thread (2), it is characterized in that, described base portion (1) center is provided with through hole, described base portion is arranged screw thread (2), described screw thread (2) is provided with groove (3), the edge of described groove (3) is welded with high rapid-result tool steel (4).
2. extruder screw bimetallic thread bush according to claim 1, is characterized in that, described base portion (1) adopts 38CrMoALA high-quality nitrated steel.
