Description

Technical Field

[0001] The utility model relates to the technical field of steel billet processing, in particular to a cutting slag removing device. Background Art

[0002] In the process of billet production in steel mills, the billet is usually cut to size, and slag will be formed at the head of the billet during the cutting process. In the process of wire rolling in steel mills, the residual slag at the head of the billet will cause the billet to be unable to enter the rolling mill normally, resulting in abnormal production. Or after the billet enters the rolling mill, the presence of billet slag will cause surface defects on the finished product or the roller will be broken due to excessive force, seriously affecting the service life of the equipment. The existence of slag is a problem that steel mills need to solve urgently. Whether it is during billet transportation or wire production, the existence of slag will cause certain troubles.

[0005] A slag removal device comprises a baffle plate, a through hole is provided on the baffle plate, the size of the through hole is not smaller than the steel billet with slag, the outer side of the baffle plate is connected to a first guide groove located on both sides of the through hole, and a mechanical cutter is provided in the first guide groove to slide along the first guide groove.

[0006] The two mechanical cutting knives slide toward each other until their inner ends are assembled into a closed knife frame, and the closed knife frame removes the cutting slag at the head of the steel billet;

[0007] The outer ends of the two mechanical cutters are hinged with second connecting rods, and the other ends of the two second connecting rods are hinged at the same driving hinge point. The baffle is also connected with a driving member for controlling the driving hinge point to approach or move away from the through hole position.

[0008] By adopting the above technical scheme, the driving member drives the operation, and through the hinge mechanism, the two sets of mechanical cutting knives are closed synchronously to remove the slag on the head of the steel billet coming out of the pinch roller, and when the driving member is reset, the two sets of mechanical cutting knives are opened synchronously without removing the slag. The two sets of mechanical cutting knives can be closed synchronously accurately to achieve the effect of removing the slag.

[0009] Furthermore, the driving member includes a driving cylinder.

[0010] By adopting the above technical solution, driven by the cylinder, the two sets of mechanical cutting knives can be accurately closed synchronously to achieve the effect of removing cutting slag.

[0011] Furthermore, the baffle is connected with a second guide groove arranged toward the through hole, and the driving hinge point is slidably connected in the second guide groove.

When the cylinder is opened, the hinge mechanism is used to synchronize the closing of two sets of mechanical cutters, and the slag on the head of the billet coming out of the pinch roller is removed. When the cylinder is retracted, the two sets of mechanical cutters are synchronized and the slag is not removed.

[0025] It can effectively remove the cutting slag at the head of the billet. Driven by the cylinder, it can accurately achieve the synchronous closing of two sets of mechanical cutting knives to achieve the effect of removing the cutting slag.

[0026] The device is simple and reliable, the connecting rod mechanism and the slider mechanism are easy to maintain and repair, and the cutter is easy to replace when it is worn. The device has a good effect on the wire rolling of the steel plant;

[0027] The device can not only remove the cutting slag at the head of the billet, but also remove the iron oxide scale on the surface of the billet. Under normal circumstances, the iron oxide scale on the surface of the billet coming out of the heating furnace is removed by a descaling machine. When the descaling machine fails, the cylinder is operated to make the cutting knife contact the surface of the billet to remove the iron oxide scale and ensure the quality of the finished product.

The size of the through hole is not smaller than the steel billet 8 with cutting slag, that is, slightly larger than the steel billet 8, so as to allow the steel billet 8 with cutting slag to pass through.

[0036] The upper and lower pinch rollers 12 are connected between the two side plates 13, and the steel billet 8 with cut slag is transported forward by the two pinch rollers 12. The baffle 7 is connected to the front ends of the two opposite side plates 13 through a plurality of second bolts 6, and the through holes are aligned with the forward direction of the steel billet 8.

[0037] like Figure 2 As shown, the outer side of the baffle 7 is fixedly connected to the first guide grooves 10 located on both sides of the through hole thereof, and the first guide grooves 10 are provided with mechanical cutting knives 9 sliding along the first guide grooves 10, and the two mechanical cutting knives 9 slide toward each other until the inner ends thereof are assembled into a closed knife frame, and the closed knife frame removes the cutting slag at the head of the billet 8;

[0038] The outer ends of the two mechanical cutting knives 9 are hinged with second connecting rods 5, and the other ends of the two second connecting rods 5 are hinged at the same driving hinge point. The baffle 7 is also connected with a driving member for controlling the driving hinge point to approach or move away from the through hole position;

[0039] In this embodiment, the driving member includes a driving cylinder 1, which is fixed to the outside of the baffle 7 by four first bolts 2. The driving cylinder 1 includes a piston rod 3 at the output end, the outer end of the piston rod 3 is hinged to the first connecting rod 4, and the other end of the first connecting rod 4 is hinged to the driving hinge point; the piston rod 3 and the first connecting rod 4 are set at an obtuse angle.

[0040] like Figure 2 As shown, the baffle 7 is connected with a second guide groove 11 arranged toward the through hole, the driving hinge point is slidably connected in the second guide groove 11, and the driving hinge point can be sleeved with a roller to facilitate its sliding along the second guide groove 11; in this embodiment, the driving cylinder 1 is horizontally arranged, the first guide groove 10 is arranged upward at 45 degrees, the second guide groove 11 is perpendicular to the first guide groove 10, and the two mechanical cutting knives 9 and the first guide groove 10 are symmetrically arranged on both sides of the through hole about the second guide groove 11;

[0041] The mechanical cutter 9 includes a V-shaped blade at the inner end, and the two V-shaped blades are assembled into a rectangular closed knife frame. The mechanical cutter 9 is installed in the first guide groove 10, and the cutter is closed or opened by the operation of the driving cylinder 1; in this embodiment, the two sides of the V-shaped blade are perpendicular and equal to each other, the through holes of the steel billet 8 and the baffle 7 are square, and the through hole of the baffle 7 is slightly larger than the steel billet 8.
