Chute sideslip device is cut to garrulous limit
Technical Field
The invention relates to the technical field of metallurgical equipment, in particular to a chute transverse moving device for a scrap chopper.
Background
In the metallurgical industry, the scrap shears are used on shearing machines, and scrap edges which are sheared off by a circle shear and run are sheared into fragments, so that the fragments are convenient to collect, recycle and utilize. However, the existing slitter edge chute is directly fixed on the cutter box, the slitter edge shears are powered by a motor to drive the upper cutter head body and the lower cutter head body of the slitter edge shears to rotate, six slitter edge shearing blades are arranged on each cutter head body, and when slitter edges enter the shearing positions of the upper cutter head body and the lower cutter head body through the slitter edge chute, the slitter edge shearing blades shear the slitter edges into small sections. However, the scrap chute of the existing scrap cutter device is fixedly mounted on the cutter box by six bolts and cannot move, although the length of the scrap cutter blade is only 220mm in the length direction, only one second station 18 (as shown in fig. 3) in the middle of the cutter blade is needed during actual scrap cutting, the scrap cutter blade always works at one station, and the other two stations of the cutter blade cannot be used.

The rear gland is fixed at two ends of the fixed shaft seat, the groove at the outer edge of the middle part of the screw nut is in clearance fit with a hole formed by the rear gland and the front gland at one end of the fixed shaft seat, bosses for axially positioning the screw nut are arranged at two sides of the groove at the outer edge of the middle part, and a hole for rotating the screw nut is arranged on the circumference of the boss at the outer side of the screw nut; the screw rod passes through the screw nut, then passes through a hole formed by a rear gland and a front gland at the other end of the fixed shaft seat, and is in clearance fit connection with the slitter edge chute, and the upper gland axially positions the screw rod in the hole of the slitter edge chute through a boss on the screw rod; the guide rod is positioned below the screw rod, the guide rod penetrates through holes formed by the rear gland and the front gland at the two ends of the fixed shaft seat and is connected with the slitter edge chute, the guide rod is axially positioned in the hole of the slitter edge chute by the lower gland through a lug boss on the guide rod, and one end of the guide rod is provided with an elongated slot for radially positioning the fastening handle.
Two ends of the lower guide rod are respectively provided with a first limiting ring and a second limiting ring; the guide rod is provided with a pointer, and the fixed shaft seat is provided with a dial.
And a fastening handle is arranged on the front gland at one end of the fixed shaft seat.
Compared with the prior art, the movable scrap edge chute can guide the scrap edges to enter all the cutting edge shearing point positions of the scrap edge shearing blades, so that the original scrap edge shearing blades are lifted to all the working positions by using only one working position, the use efficiency and the production efficiency of the scrap edge shearing blades are effectively improved, the service life of the scrap edge shearing blades is greatly prolonged, and the tool changing frequency and the labor cost are reduced.
