Abstract
The utility model relates to a circular arc key between a disc cutter shaft and a longitudinal cutter blade in slitting machine unit, belonging to the technical field of board strip processing machine, which comprises a dark groove (4) arranged on an inner surface (5) of a blade (1) or the longitudinal cutter blade, a groove (6) arranged on an external surface (7) of the disc cutter shaft, and a circular key (2) for location arranged inside the dark groove (4) and the groove (6). The new circular arc keyway of the utility model has the advantages of effectively avoiding the blocking phenomenon of the blade and spacer ring by the contact surface of the flat key as the assembly and disassembly and enabling precise positioning.
Description
Technical field
The utility model relates to strip material processing equipment technical field, especially relates to the circular arc key on the shading ring between circle shear cutter shaft in a kind of slitter unit and slitting blade or the blade.
Background technology
At present, employed key is conventional flat key on the circle shear cutter shaft in the slitter unit.Yet because set shading ring reaches tens even up to a hundred between slitting blade on the circle shear cutter shaft and the blade thereof, when adopting flat key to connect, because they are plane contact, stuck by the contact plane of flat key easily when mounting or dismounting blade and shading ring, and the location is not accurate enough usually.
Summary of the invention
For overcoming existing in prior technology the problems referred to above, the purpose of this utility model provides the circular arc key between the circle shear cutter shaft and slitting blade in a kind of slitter unit, when not only can avoiding installing and removing blade and shading ring effectively, this circular arc key, and can realize the accurately purpose of location by the generation of the contact plane stuck phenomenon of flat key.
For achieving the above object, the utility model adopts following technical scheme:
Circular arc key in a kind of slitter unit between circle shear cutter shaft and the slitting blade is provided with undercut on the blade inner face of slitting blade or blade, the circle shear cutter shaft periphery of circle shear cutter shaft is provided with groove, and the round key location is set in undercut and groove.
Circular arc key in this slitter unit between circle shear cutter shaft and the slitting blade, round key can be designed to circle, ellipse, square and polygonal.
Circular arc key in this slitter unit between circle shear cutter shaft and the slitting blade, undercut and groove are changed into the shape that matches with it simultaneously when round key changes shape.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
The utility model is owing to adopted the round key connection, shading ring location between circle shear cutter shaft and slitting blade and the blade thereof is very accurate, because round key is the little matched in clearance of basic hole system with cooperating of circular arc keyway, when mounting or dismounting blade and shading ring, blade is the line contact with shading ring and contacting of round key, and frictional force is little, and mounting or dismounting blade and shading ring are very smooth and easy, can avoid the generation of stuck phenomenon effectively, result of use is better than prior art greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the undercut structural representation of slitting blade of the present utility model or blade;
Fig. 3 is the groove structure schematic diagram of circle shear cutter shaft of the present utility model;
Among the figure: 1-slitting blade or blade; The 2-round key; 3-circle shear cutter shaft; The 4-undercut; 5-blade inner face; The 6-groove; 7-circle shear cutter shaft periphery.
The specific embodiment
Can explain the utility model in more detail by the following examples;
In Fig. 1,2,3: the circular arc key in a kind of slitter unit between circle shear cutter shaft and the slitting blade, on the blade inner face (5) of slitting blade or blade (1), be provided with undercut (4), the circle shear cutter shaft periphery (7) of circle shear cutter shaft (3) is provided with groove (6), during the corresponding installation of groove (6) on the undercut (4) on blade inner face (5) and the circle shear cutter shaft periphery (7) of circle shear cutter shaft (3), round key (2) inserted get final product.
Claims (3)
1. the circular arc key between circle shear cutter shaft and the slitting blade in the slitter unit, it is characterized in that: on the blade inner face (5) of slitting blade or blade (1), be provided with undercut (4), the circle shear cutter shaft periphery (7) of circle shear cutter shaft (3) is provided with groove (6), and round key (2) location is set in undercut (4) and groove (6).
2. the circular arc key in the slitter unit according to claim 1 between circle shear cutter shaft and the slitting blade is characterized in that: round key (2) can be designed to circle, ellipse, square and polygonal.
3. the circular arc key in the slitter unit according to claim 1 and 2 between circle shear cutter shaft and the slitting blade is characterized in that: undercut (4) is changed into the shape that matches with it simultaneously with groove (6) when round key (2) changes shape.
