Abstract
The utility model relates to a circular disk scissor pressing plate ring, particularly a heat emitting circular disk scissor pressing plate ring, which comprises pressing plate iron cores and a pressing ring. The inner ring of the pressing plate ring iron cores is sheathed on a shaft and the outer ring is coated with the pressing ring. The utility model is characterized in that the pressing plate ring iron cores are circular rings. The cross sections of the circular rings are head-shoulder-shaped along the radial direction. The head-shoulder-shaped circular rings are provided with a plurality of through holes along the shaft direction. The head-shoulder-shaped circular rings of the pressing plate ring iron cores are arranged symmetrically. The shaft direction through holes of the pressing plate ring iron cores are uniformly arranged along a circumference. The diameter of the circumference is the diameter of the intersecting position of the head-shoulder-shaped circular rings. The utility model improves the heat emitting performance of circular disk scissors and lengthens the service life of the cutting blade of the circular disk scissors and simultaneously, reduces the weight of the pressing plate ring and alleviates the labor intensity of operators.
Description
(1) technical field
The utility model relates to circle shear pressing plate circle.
(2) background technology
The circle shear shear is steel band both sides limit portion to be carried out directed size shear.The pressing plate circle is to be loaded on that the circle shear cutting edge is outer to pin and then push down cutting edge by hydraulic nut, and it axially stablize the cutting edge while and radially pushes down and be sheared steel band.Existing pressing plate circle is that whole face is close to the circle shear cutting edge, because cutting edge and steel band are sheared friction for a long time, cutting edge can generate heat, and existing pressing plate coil structures is unfavorable for the cutting edge heat radiation; And the nylon pressing plate circle heat dispersion that macromolecule is done is poor; Because steel band production carries out continuously, and do not wait the cutting edge of heating to cool down, the steel band head of next volume has been put on again, and long-time blade heating is sheared and is caused cutting edge to grind pure or cutting edge generation chipping, thereby reduction blade service life influences the steel band quality of edges.Simultaneously a circle shear pressing plate circle weight can reach about 90 kilograms because the restriction of circle shear installing space can only hold a people and change operation, so the operator to change circle shear labour intensity big.
(3) summary of the invention
The utility model has overcome that existing pressing plate circle heat dispersion is poor, the defective of Heavy Weight, and a kind of heat radiation circle shear pressing plate circle is provided.This heat radiation circle shear pressing plate circle adopts Head and Shoulders annulus, has axially extending bore on annulus, has so both improved the circle shear heat dispersion, has alleviated the weight of pressing plate circle again, has prolonged circle shear service life.
The utility model is achieved in that a kind of heat radiation circle shear pressing plate circle, comprise the unshakable in one's determination and macromolecule trim ring of pressing plate circle, pressing plate circle inner ring unshakable in one's determination is enclosed within on the axle, the outer ring is surrounded by the macromolecule trim ring, it is characterized in that pressing plate circle iron core is annulus, the cross section of annulus radially is a Head and Shoulders, has several through holes on the Head and Shoulders annulus vertically.
Above-mentioned heat radiation circle shear pressing plate circle, the Head and Shoulders annulus of described pressing plate circle iron core is for being symmetrically distributed.
Above-mentioned heat radiation circle shear pressing plate circle, the axially extending bore of described pressing plate circle iron core are for evenly to distribute along circumference, and the diameter of described circumference is Head and Shoulders annulus intersection.
The utility model is compared with existing pressing plate coil structures, owing to adopt the Head and Shoulders annulus, on annulus, have axially extending bore, the heat that the circle shear cutting edge produces can be excluded by step gap between cutting edge and pressing plate circle and pressing plate circle axially extending bore, thereby improved the circle shear heat dispersion, prolonged circle shear service life.The axially extending bore that has on the pressing plate circle had simultaneously both played the effect of getting rid of the cutting edge heat, reduced the weight of pressing plate circle again, had alleviated the labour intensity that the operator changes circle shear.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the partial schematic diagram of circle shear device;
Fig. 2 is the utility model heat radiation circle shear pressing plate coil structures schematic diagram;
Fig. 3 is the side view of Fig. 2.
Among the figure: 1 inboard hydraulic locking nut, 2 circle shear cutting edges, 3 pressing plate circles, 4 outside hydraulic locking nuts, 5,6 through holes, 7 pressing plate circle iron cores, 8 trim rings, 9 head annulus, 10 shoulder annulus.
(5) specific embodiment
Referring to Fig. 2, Fig. 3, a kind of heat radiation circle shear pressing plate circle 3 comprises pressing plate circle unshakable in one's determination 7 and trim ring 8, and pressing plate circle 7 inner rings unshakable in one's determination are enclosed within on the axle 5, and the outer ring is surrounded by trim ring 8, and trim ring 8 is made by macromolecule, as fluorubber.Pressing plate circle unshakable in one's determination 7 is an annulus, and the cross section of annulus radially is a Head and Shoulders, and the Head and Shoulders annulus of pressing plate circle iron core 7 is for being symmetrically distributed.Have several through holes 6 on the Head and Shoulders annulus of pressing plate circle iron core 7 vertically, axially extending bore 6 is for evenly to distribute along circumference, the diameter of this circumference is Head and Shoulders annulus intersection, the center of circle that is through hole 6 places on the intersecting lens of Head and Shoulders annulus, like this a half-sum of through hole 6 second half be in respectively on head annulus 9 and the shoulder annulus 10.In the present embodiment, the quantity of through hole 6 is eight, and is uniform along annulus unshakable in one's determination 7.
Referring to Fig. 1, assembling schematic diagram in the part of circle shear device comprises the axle 5 that connects gear-box, is set with inboard hydraulic locking nut 1, circle shear cutting edge 2, pressing plate circle 3, outside hydraulic locking nut 4 on the axle 5.Pressing plate circle 3 is close to circle shear cutting edge 2, and pressing plate circle iron core 7 is pushed down by outside hydraulic locking nut 4.Because pressing plate circle iron core 7 is for the Head and Shoulders annulus and have through hole 6, cutting edge 2 and outside hydraulic nut 4 are close in head annulus 9 two sides, and 4 of shoulder annulus 10 two sides and cutting edge 2 and outside hydraulic nuts are gapped, and have through hole 6 to connect.Like this when axle 5 rotates, drive cutting edge 2 rotates to be sheared the band steel, and at pressing plate circle 7 shoulder annulus 10 unshakable in one's determination and 2 of cutting edges and 4 generations of outside hydraulic locking nut air-flow, this air-flow is taken away the heat that cutting edge 2 produces simultaneously, thereby reduce cutting edge 2 temperature, improved 2 service lifes of cutting edge.
The utility model the results showed that radiating effect is good, and cutting edge is brought up to original 1.4 times service life, and the weight saving of pressing plate circle.
