Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying examples.

Referring to the attached drawings 1 and 2, the automatic grinding cutting device comprises a frame body 1, wherein a cylinder 2 is welded on the bottom surface of the frame body 1, the fixed end of the cylinder 2 is welded with the top surface of the frame body 1, the extending end of the cylinder 2 is welded with a cutting knife 3, and the cylinder 2 drives the cutting knife 3 to move up and down to cut profile steel. The knife face bilateral symmetry of cutting knife 3 is provided with base 4, and one side that base 4 is close to cutting knife 3 is fixed with magnet 5. Two bottom holes 18 have been seted up on base 4, and bottom hole 18 is located magnet 5 and keeps away from one side of another magnet 5, and spout 6 has been seted up to the upper surface of base 4, and spout 6 is perpendicular with the knife face of cutting knife 3, and four slotted holes 7 have evenly been seted up to the both sides face of spout 6, and slotted hole 7 interpolation is equipped with grooved bar 8, and grooved bar 8's length direction is parallel with the knife face of cutting knife 3, and the slip is provided with slider 9 on spout 6. Base 4 keeps away from one side of magnet 5 and is equipped with two telescopic links 10, telescopic link 10 includes interior pole 12 and outer pole 13, outer pole 13 cover is established outside interior pole 12, interior pole 12 is kept away from the one end of outer pole 13 and is articulated with the base, interior pole 12 goes up the shaping has and holds chamber 14, it is equipped with No. two springs 15 and lockpin 16 to hold the intracavity 14, No. two springs 15 one end and the bottom surface butt that holds chamber 14, No. two springs 15's the other end and lockpin 16's bottom surface butt, lockpin 16 exposes from the opening that holds chamber 14, six shrinkage pools 17 have evenly been seted up on the outer pole 13, shrinkage pools 17 arranges along outer pole 13 length direction, shrinkage pools 17 and lockpin 16's shape and position adaptation. A first spring 11 is arranged between the telescopic rod 10 and the base 4, one end of the first spring 11 is welded on the inner rod 12, and the other end of the first spring 11 is welded on the upper surface of the sliding block 9.

Referring to fig. 1 and fig. 3, one end of the telescopic rod 10 far away from the base 4 is provided with a sharpening roller 19, the length direction of the sharpening roller 19 is parallel to the knife surface, the sharpening roller 19 on two sides of the cutting knife 3 clamps the cutting knife 3, the length of the sharpening roller 19 is equal to that of the cutting knife 3, the sharpening roller 19 comprises an inner roller 20 and an outer roller 21, and the outer roller 21 is sleeved outside the inner roller 20. Interior roller 20's both sides and telescopic link 10 welded connection, evenly formed has six tooth chamber 22 on interior roller 20's the curved surface, and tooth chamber 22 is interval distribution, and it has jack 23 to articulate on tooth chamber 22's the lateral wall, is equipped with No. three spring 24 between jack 23 and the bottom surface in tooth chamber 22, and No. three spring 24 one end and jack 23 butt, No. three spring 24's the other end and the bottom surface butt in tooth chamber 22, and No. three spring 24 is in compression state. Even shaping has twelve ratchets 25 on the inboard curved surface of outer roller 21, and ratchets 25 are interval distribution, and ratchets 25 are the joint cooperation with jack tooth 23, and through such setting, outer roller 21 can rotate along with cutting knife 3 when cutting knife 3 whereabouts, and when cutting knife 3 retrieved upwards, outer roller 21 rotated certain distance after the card die, made the blade of cutting knife 3 not excessively rubbed, guaranteed simultaneously that the knife tip of cutting knife 3 is polished.

The working principle of the embodiment is as follows: when the cutting knife 3 falls to cut the section steel, the cutting knife 3 penetrates through the space between the two knife grinding rollers 19, and the knife grinding rollers 19 are driven by the cutting knife 3 to rotate, so that the falling of the cutting knife 3 is prevented from being blocked; when the cutting knife 3 finishes the cutting of the profile steel and then lifts up, the knife sharpening roller 19 is locked and can not rotate reversely, the knife sharpening roller 19 and the cutting knife 3 rub against each other, and the cutting knife 3 is polished. The tooth chamber 22 and the interval distribution of ratchet 25 make the cutter knife 3 can rotate certain angle when upwards lifting up by knife sharpening roller 19, and cutter knife 3 can not be too early ground by knife sharpening roller 19 many degrees, has also prevented when the knife tip of cutter knife 3 has been guaranteed to be ground that the blade of cutter knife 3 is excessively polished. A spring 11 between the telescopic rod 10 and the base 4 enables the knife sharpening roller 19 to be tighter with the joint when the cutting knife 3 is sharpened, and the sharpening effect is better. Along with the increase of the number of times of polishing, the blade of cutting knife 3 is constantly becoming thin, can adjust the slider 9 position this moment and make No. one spring 11 keep tightening and guarantee that knife grinding roller 19 is hugged closely with cutting knife 3 all the time. When the lifting amplitude of the cutting knife 3 changes or the size of the cutting knife 3 changes, the length of the telescopic rod 10 is adjusted to change the included angle between the telescopic rod 10 and the base 4, so that the purpose of adapting to the cutting knives 3 with different lifting amplitudes and different sizes is achieved.

By adopting the scheme, the cutting and polishing of the cutting knife 3 are simultaneously carried out, the cutting knife 3 is polished without stopping the production line, and the production efficiency of the profile steel production line is improved; meanwhile, the cutting knife 3 is kept sharp all the time, the cutting effect of the section steel is better, and burrs on the edge of the section steel after cutting are reduced.

The above, only do the preferred embodiment of the present invention, not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
