Description
Technical field
The utility model relates to building machinery technical field, particularly relates to angle-bender.
Background technology
Angle-bender has panel above, in the middle of panel above, there is axis hole, axis hole is provided with rotating shaft, above rotating shaft, be connected with crooked dish, in prior art, the axis hole of panel is around all the structure of planar shaped, and the dust forming in BENDING PROCESS like this will fall into axis hole easily, pollute whole machine, even affect the service life of bending machine.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of and is difficult for falling into dust, reduces the harm of machine, the dustproof angle-bender that increases the service life.
The technical solution of the utility model is achieved in that dustproof angle-bender, comprise panel above, in the middle of panel above, there is axis hole, through axis hole, rotating shaft is installed, above rotating shaft, be connected with crooked dish, it is characterized in that: described axis hole around has the protrusion ring of a week upward, is also socketed with rubber ring on projection circle, the upper end of rubber ring with and crooked dish below contact.
Saying further, is the structure of attenuation above described rubber ring.
Say further to there is a circle groove below described bending dish, the groove that described groove is and protrusion ring coordinates, protrusion ring upper end is goed deep in groove.
The beneficial effects of the utility model are: the angle-bender of this spline structure has advantages of and is difficult for falling into dust, reduces the harm of machine, increases the service life; It above described rubber ring, is the structure of attenuation, can reduce the advantage of rubber ring to rotating disk running resistance: below described bending dish, there is a circle groove, described groove is the groove coordinating with protrusion ring, and protrusion ring upper end is goed deep in groove, has the better advantage of dust-proof effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model angle-bender.
Wherein: 1, panel 2, axis hole 3, rotating shaft 4, protrusion ring 5, rubber ring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, dustproof angle-bender, comprise panel 1 above, in the middle of panel above, there is axis hole 2, through axis hole, rotating shaft 3 is installed, above rotating shaft, is connected with crooked dish, it is characterized in that: described axis hole has the protrusion ring 4 of a week upward around, on projection circle, be also socketed with rubber ring 5, the upper end of rubber ring with contact below with crooked dish.
There is so good dust-proof effect.
Saying further, is the structure of attenuation above described rubber ring.Reduce like this resistance of rubber ring to bending dish.
Say further to there is a circle groove below described bending dish, the groove that described groove is and protrusion ring coordinates, protrusion ring upper end is goed deep in groove, and dust-proof effect is better like this.
Above embodiment is only part embodiment of the present invention, but aim of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed in the scope of the claims of the present invention.
Claims (3)
