Description

Short stress path rolling mill adjusting device for installing double guide guards

Technical Field

The utility model belongs to the technical field of metal pressure processing equipment. The adjusting device is a short stress path rolling mill adjusting device which is used for installing double guides and guards in a steel rolling mill.

Background

At present, only one set of guide and guard device can be installed on a short-stress rolling mill in a common steel rolling mill, and the hole pattern of the rolling mill is usually not single when the rolling mill rolls the same stand in the actual production process, so that the rolling mill needs to be replaced when the specification is replaced. If a plurality of sets of guides are forcibly installed, the guides cannot be independently adjusted, and the centering adjustment cannot be realized.

If two sets of different guides can be installed on one set of rolling mill, each set of guide can be independently adjusted, so that the number of roll changing and rolling groove changing is reduced, the operation rate of the rolling mill is improved, the occupation of funds is reduced, and the field labor intensity is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a two short stress line rolling mill adjustment mechanism poles of defending of mountable realizes that two sets of guides of installation are defended on a rolling mill, and each set of guide can be adjusted alone the corresponding pass central line of alignment by displacement.

The technical scheme of the utility model:

a short-stress-path rolling mill adjusting device for installing double guides and guards comprises a guide and guard frame, a female screw rod, a male screw rod, a female screw rod, a sliding block pressing block and a sliding block. The screw thread distance and the size of the screw surfaces of the female screw rod and the sub screw rod are completely consistent; one end of the female screw rod is square, so that a wrench can rotate the female screw rod conveniently, and the center of the square head is drawn out of the central through hole; one end of the sub screw rod is stretched to form a cylindrical smooth surface which is 30-50 mm longer than the total length of the female screw rod, and the size of the cylindrical smooth surface is in clearance fit with the size of a central through hole of the female screw rod between H/d stages; making a sub square head 30-50 mm behind the end of the sub screw rod; and a group of square sliding blocks are respectively arranged on the surfaces of the female screw rod and the male screw rod. When the female screw rod or the sub screw rod is rotated, the square sliding block is restricted not to rotate along with the female screw rod or the sub screw rod, and therefore the transverse movement is generated. Because the female screw rod or the sub screw rod can rotate independently without mutual interference, the guide installed on the female screw rod or the sub screw rod moves independently without interfering with the other guide.

The utility model has the advantages that: the utility model discloses the device can realize installing two sets and lead the defending on the crossbeam, leads and defends adjustment mutually noninterfere, realizes that two sets of guides of a rolling mill installation are installed two sets of pass on same rolling mill, trades the pass, trades the purpose that the groove can conveniently go on.

Detailed Description

The following further describes the embodiments with reference to the drawings.

FIGS. 1 to 6 show: a short stress path rolling mill adjusting device capable of being provided with double guides and guards comprises a guide and guard frame 2, a female screw rod 3, a sub screw rod 4, a sliding block pressing block 5 and a sliding block 6. The screw rod group consists of a female screw rod 3 and a male screw rod 4, and the thread distance and the size of the thread surfaces of the female screw rod 3 and the male screw rod 4 are completely consistent; one end of the female screw rod 3 is made into a female square head 16 by drawing, so that a spanner can conveniently rotate the female screw rod 3, the center of the female square head 16 is drawn out of the central through hole 17, one end of the sub screw rod 4 is drawn out of a cylindrical smooth surface 19 with the total length of 30-50 mm longer than that of the female screw rod, and the size of the cylindrical smooth surface 19 is matched with the size of the central through hole 17 of the female adjusting screw rod in an H/d stage clearance manner; 30-50 mm behind the end of the sub screw rod 4 is used as a square drawing head to form a sub square head 18, so that the screw rod can be conveniently adjusted by a rotator.
