Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1, it is a schematic structural diagram of an inlet box in front of the machine of the present invention; as shown in fig. 2, it is a schematic structural diagram of the inlet box behind the middle machine of the present invention.

An inlet guide arrangement for a rolling mill comprising: install the entry box at the rolling mill head and tail portion of reinforcing bar, the entry box includes: guide plate crossbeam 1, box body 2, gusset 3, entry baffle 4. The box body 2 is arranged at the top of the guide plate cross beam 1, and the rib plates 3 are arranged at the connecting positions of the box body 2 and the cross beam 1 and used for improving the structural strength of connection.

The box body 2 comprises at least one plug-in box, two inlet guide plates 4 are plugged in the plug-in box, and two pairs of key grooves 21 matched with the key strips 42 are arranged on the opposite inner walls of the inner sides of the plug-in box; the front ends of the two inlet guide plates 4 arranged in the same splicing box are opened towards two sides to form a certain opening angle, so that the effect of correctly guiding a rolled piece to enter a roll pass is achieved, and the occurrence of card rolling accidents is effectively reduced.
