Abstract
The utility model discloses a pair of round rolling scissors which have the characteristic of improving the service life of the rolling scissors. The rolling scissors comprise a scissors base body and blades matched at the periphery of the scissors base body; and a positioning member which is used for preventing the falling of the blades are arranged between the scissors base body and the blades. As the positioning member is arranged between the scissors base body and the blades, the inner circumferences of the blades are prevented from moving relatively along the periphery of the scissors base body in the work process, so that the blades are well prevented from falling off from the scissors base body, the service life of the rolling scissors in the utility model is greatly prolonged and the rolling scissors are suitable for popularization and application on various mosaic combined cutting tools.
Description
Technical field
The utility model discloses a kind of cutter, be specifically related to a kind of roller shear cutter of circle.
Background technology
At present, the roller shear cutter generally comprises inner matrix and the blade that is interference fitted in the matrix periphery, and matrix and blade adopt number of various materials.In use,, cause the mating surface generation between matrix and blade loosening, thereby cause blade to come off, make that the service life of this roller shear cutter is lower from matrix because blade contacts with material to be cut for a long time.
The utility model content
The utility model technical problem to be solved provides a kind of roller shear cutter that improves service life.
The utility model solves the technical scheme that its technical problem adopted: the roller shear cutter, the blade that comprises tool matrix and be engaged in the tool matrix periphery is provided with the keeper that prevents that blade from coming off between tool matrix and blade.
As optimized technical scheme, between tool matrix and blade, be provided with through hole, the part of said through hole connects tool matrix, and another part connects blade, and keeper is the bearing pin that is a tight fit in this through hole.
Further be that said bearing pin is in tilted layout in the through hole between tool matrix and blade.
Further be that said blade is interference fitted in the periphery of tool matrix.
The beneficial effect of the utility model is: owing between matrix and blade, be provided with keeper; Like this; In the course of the work, this keeper can prevent the periphery generation relative motion of the inner edge tool matrix of blade, thereby can prevent well that blade from coming off from tool matrix; Improved the service life of the utility model roller shear cutter greatly, be adapted at applying on the various cutters of inlaying combination.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view of A-A direction among Fig. 1.
Be labeled as among the figure: tool matrix 1, blade 2, bearing pin 3.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1 and shown in Figure 2, the roller shear cutter of the utility model, the blade 2 that comprises tool matrix 1 and be engaged in tool matrix 1 periphery is provided with the keeper that prevents that blade 2 from coming off between tool matrix 1 and blade 2.Owing between matrix 1 and blade 2, be provided with keeper; Like this; In the course of the work; This keeper can prevent the periphery generation relative motion of the inner edge tool matrix 1 of blade 2, thereby can prevent well that blade 2 from coming off from tool matrix 1, has improved the service life of the utility model roller shear cutter greatly.
In the above-described embodiment; The keeper that tool matrix 1 and blade 2 are positioned can adopt steel wire rope; On tool matrix 1 and blade 2, offer through hole respectively; In the through hole that utilizes steel wire rope to be set on to offer tool matrix 1 and blade 2 are carried out fasteningly, or clamp is set between tool matrix 1 and blade 2 carries out tool matrix 1 and blade 2 fastening.As preferred embodiment, between tool matrix 1 and blade 2, be provided with through hole, the part of said through hole connects tool matrix 1, and another part connects blade 2, and keeper is the bearing pin 3 that is a tight fit in this through hole.This mode is simple in structure, and the form that bearing pin 3 is a tight fit in the through hole can be to adopt the form of interference fit or interference fits.
In the above-described embodiment, the axis of through hole can be perpendicular to the surface of tool matrix 1 and blade 2 between tool matrix 1 and the blade 2, but in the long-term course of work of cutter, causes bearing pin 3 from this through hole, to come off easily.As preferred embodiment, said bearing pin 3 is in tilted layout in the through hole between tool matrix 1 and blade 2.As shown in Figure 2, this mode can effectively increase the friction between bearing pin 3 and the through hole, thereby can effectively prevent coming off of bearing pin 3.
In above embodiment; Can there be certain clearance between blade 2 and the tool matrix 1; But the resistance that when cutter is worked, produces is basically all born by bearing pin 3, and as preferred embodiment, said blade 2 is interference fitted in the periphery of tool matrix 1; Like this, can prevent more effectively that blade 2 from coming off from tool matrix 1.
Claims (4)
1. roller shear cutter, the blade (2) that comprises tool matrix (1) and be engaged in tool matrix (1) periphery is characterized in that: between tool matrix (1) and blade (2), be provided with the keeper that prevents that blade (2) from coming off.
2. roller shear cutter as claimed in claim 1; It is characterized in that: between tool matrix (1) and blade (2), be provided with through hole; The part of said through hole connects tool matrix (1), and another part connects blade (2), and keeper is the bearing pin (3) that is a tight fit in this through hole.
3. roller shear cutter as claimed in claim 2 is characterized in that: said bearing pin (3) is in tilted layout in the through hole between tool matrix (1) and blade (2).
4. like claim 1,2 or 3 described roller shear cuttves, it is characterized in that: said blade (2) is interference fitted in the periphery of tool matrix (1).
