Description
Technical field
The present invention relates to the adjustment of the drum type flying shear blade clearance on continuous belt steel process line, particularly relate to a kind of shearing edge gap adjusting device of drum type flying shear.
Background technology
Rotary flying shears have that shear rate is fast, structure is simple, knife adjustment precision high, are therefore widely used in continuous belt steel process unit.The quality of size to shearing area of its blade clearance plays an important role, and generally adopts at present, uses spanner rotating nut, then fixes with bolt and pin and nut check, and adjust the blade clearance of rotary flying shears, its Adjustment precision is low, wastes time and energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide the shearing edge gap adjusting device of the drum type flying shear that a kind of structure is simple, Adjustment precision is high and time saving and energy saving.
In order to solve the problems of the technologies described above, the invention provides a kind of shearing edge gap adjusting device of drum type flying shear, this device includes frame, worm bearing, worm shaft, worm gear and adjusting nut, described frame is fixed with worm bearing, described worm bearing is connected with worm shaft, and described worm shaft also engages with worm gear, and one end of described worm shaft is fixed with handwheel, described worm gear is connected with adjusting nut by key, and the inner side of described adjusting nut is bolted with the upper drum shaft of drum type flying shear.
Further, a part for described key embeds worm gear, and another part of described key embeds adjusting nut, and the relative worm gear of described key can do axially-movable, and the relative worm gear of described adjusting nut can do axially-movable.
Further, described key is two.
Further, described worm gear bearing front end is fixed with end cap.
Further, described worm gear bearing is fixed with slide plate, is fixed with slide plate inside described end cap, two described slide plates retrain the end face of worm gear jointly.
The present invention is applied on continuous belt steel process line, make use of the feature of worm gear and worm shaft big speed ratio, can obtain high-precision shears blades space adjustment, also uses worm gear and worm shaft latching characteristics, ensure that the stability of the blade clearance of drum type flying shear.
Accompanying drawing explanation
Fig. 1 is the structure chart of shearing edge gap adjusting device one embodiment of drum type flying shear of the present invention.
In figure, 1. handwheel, 2. worm shaft, 3. worm gear, 4. key, 5. adjusting nut, 6. worm bearing, 7. end cap, 8. slide plate, 9. support, 10. go up drum shaft.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
As shown in Figure 1, for an embodiment of the shearing edge gap adjusting device of drum type flying shear of the present invention, this device includes frame 9, worm bearing 6, worm shaft 2, worm gear 3 and adjusting nut 5, described frame 9 is fixed with worm bearing 6, described worm bearing 6 is connected with worm shaft 2, and described worm shaft 2 also engages with worm gear 3, and one end of described worm shaft 2 is fixed with handwheel 1, described worm gear 3 is connected with adjusting nut 5 by key 4, and the inner side of described adjusting nut 5 is bolted with the upper drum shaft 10 of drum type flying shear.
A part for described key 4 embeds worm gear 3, and another part of described key 4 embeds adjusting nut 5, and described key 4 relatively worm gear 3 can do axially-movable, and described adjusting nut 5 relatively worm gear 3 can do axially-movable, and described key is two in the present embodiment.
Described worm gear bearing 6 front end is fixed with end cap 7, described worm gear bearing 6 is fixed with slide plate 8, is also fixed with slide plate 8 inside described end cap 7, two described slide plates 8 retrain the end face of worm gear 3 jointly, prevent worm gear off-axis when rotated, avoid causing unnecessary mechanical wear.
Detailed description of the invention as shown in Figure 1, first the rotation of handwheel 1 and then drive worm shaft 2 is rotated, because worm shaft 2 engages with worm gear 3, therefore worm shaft 2 has driven worm gear 3 to rotate, now worm gear 3 drives the rotation of adjusting nut 5 by two keys 4, now axially-movable done by the relative worm gear 3 of described key 4, and described adjusting nut 5 is while rotation, and relative worm gear 3 also does axially-movable.
Be spirally connected inside described adjusting nut 5 the upper drum shaft 10 of drum type flying shear, screw thread due to upper drum shaft 10 periphery has balanced out the rotation effect of adjusting nut 5, above drum shaft 10 only follow adjusting nut 5 and do axial horizontal displacement, thus the blade clearance of adjustment drum type flying shear further.According to the difference in the direction that handwheel 1 rotates, make adjusting nut 5 while rotation, relative worm gear 3 can do axially-movable to the left or to the right.
Owing to present invention utilizes the feature of worm gear 3 and worm shaft 2 big speed ratio, therefore, it is possible to obtain the adjustment of high-precision blade clearance.
Because the end face of worm gear 3 is retrained by two slide plates 8 be fixed on inside worm gear bearing 6 and end cap 7 respectively, and after adjustment completes, worm shaft 2 and worm gear 3 can self-lockings, thus ensure that the stability of the blade clearance of drum type flying shear.
The present invention changes the method in the past rotating adjusting nut 5 with spanner, avoid the unstability that the mode in the past must fixed by bolt, pin and locking nut adjusts fixing blade clearance, improve condition of work greatly, reach time saving and energy saving object.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
