Abstract

The invention discloses an online flying shear guide roller way reinforcing structure which comprises a rack, wherein two ends of a flat roller shaft are fixed in bearings, the bearings are fixed on the rack, and the flat roller is fixed on the flat roller shaft; reinforcing structures are arranged on the outer portions of the frames at two ends of the flat roll shaft, each reinforcing structure comprises a cylindrical support body fixed on the flat roll shaft, a support ring is arranged outside each support body, and the outer side of each support body is abutted to the inner side of each support ring; the support ring is fixed on the outer side of the frame; the vertical roller and the compression roller are further included, the upper portion of the vertical roller is connected with the rack through a bearing, and the portion, exceeding the rack, of the vertical roller shaft is also provided with the reinforcing mechanism. The invention has the advantages that: the flat roll shaft is supported at two ends instead of a semi-suspension state, so that the strength of the flat roll is greatly improved in the stress process. In addition, a reinforcing structure is added for improving the stress structure of the bearing, and the service life of the bearing is ensured.

Description

Reinforcing structure for guide roller way of online flying shear

Technical Field

The invention relates to the technical field of metallurgical machinery, in particular to a roller way reinforcing structure in rolling production.

Background

The large-rod flying shear is originally designed with an inlet guide wheel, steel is centered through the guide wheel, and the steel is cut by the flying shear to finish the action. However, the original design of the device has some disadvantages in the use process in recent years: the inlet guide wheel flat roll is a driven roll, is in a semi-suspension state during design, is weak in bearing force, sometimes needs to be broken at a flying shear when a rolling line is in a problem, is bent due to large stress of the flat roll, is difficult to recover, and is long in processing time; the flat roll is in a semi-suspended state, so that the bearing connected with the flat roll shaft and the rack is stressed greatly, and the bearing is damaged frequently.

Disclosure of Invention

In order to solve the technical problem, the shaft of the flat roll is modified through field actual investigation and determination, and the semi-suspension state is changed into the through shaft, so that the strength of the flat roll is greatly improved in the stress process. In addition, increase reinforced structure for improve the atress structure of bearing, guaranteed the life of bearing, concrete technical scheme is as follows:

an online flying shear guide roller way reinforcing structure comprises a rack, wherein two ends of a flat roller shaft are fixed in bearings, the bearings are fixed on the rack, and the flat roller is fixed on the flat roller shaft; reinforcing structures are arranged on the outer portions of the frames at two ends of the flat roll shaft, each reinforcing structure comprises a cylindrical support body fixed on the flat roll shaft, a support ring is arranged outside each support body, and the outer side of each support body is abutted to the inner side of each support ring; the support ring is fixed on the outer side of the frame; the vertical roller and the compression roller are further included, the upper portion of the vertical roller is connected with the rack through a bearing, and the portion, exceeding the rack, of the vertical roller shaft is also provided with the reinforcing mechanism.

The support ring is semicircular or integral circular ring type.

The supporting ring at the outer side of one end of the flat roller shaft is semicircular, and the supporting ring at the other end of the flat roller shaft is in an integral annular shape.

The support body excircle is conical along the axial, support ring inboard and support body excircle cooperation.

The included angle between the excircle of the support body and the horizontal direction is 1.8-2.5 degrees along the axial direction.

The invention has the advantages that: the flat roll shaft is supported at two ends instead of a semi-suspension state, so that the strength of the flat roll is greatly improved in the stress process. In addition, a reinforcing structure is added for improving the stress structure of the bearing, and the service life of the bearing is ensured.

Drawings

FIG. 2 is a left side view of FIG. 1;

fig. 3 is an enlarged schematic view of a portion a of fig. 1.

Detailed Description

The invention is described in detail below with reference to the accompanying drawings, as shown in the figures, the invention comprises a frame 1, two ends of a flat roll shaft 2 are fixed in bearings 4, the bearings 4 are fixed on the frame 1, and a flat roll 3 is fixed on the flat roll shaft 2; the outer parts of the frames at two ends of the flat roll shaft 2 are provided with reinforcing structures, the reinforcing structures comprise cylindrical supporting bodies 5 fixed on the flat roll shaft, supporting rings 6 are arranged outside the supporting bodies 5, the outer sides of the supporting bodies 5 are abutted with the inner sides of the supporting rings, and the structures ensure that the supporting bodies 5 can rotate in the supporting rings 6; the support ring 6 is fixed on the outer side of the frame 1; thus, the radial impact force applied to the flat roller can be shared by the reinforcing structure, so that the bearing 4 is prevented from being damaged by larger radial force; still include edger roll 7 and compression roller 8, the top and the frame of edger roll 7 are passed through the bearing and are connected, and same reason, the part that the edger roll axle surpassed the frame also sets up strengthening mechanism. The press roll 8 is journalled to the frame by means of a rocker arm 10.

The support ring is of a semi-circular or integral circular ring type, depending on the requirements of use. As shown in fig. 1, the semicircular support ring 6 can be arranged below the flat roller shaft, also can be arranged on the side surface, and can be adjusted according to different stress directions; the support ring at one end of the flat roll shaft is semicircular, and the support ring at the other end is an integral annular support ring 11, so that the support direction can be conveniently adjusted.

For preventing to cause the damage along the axial impact force of flat roller axle to the bearing, supporter excircle 12 is conical along the axial, support ring inboard and supporter excircle cooperation.

The included angle a between the excircle of the support body and the horizontal axis is 1.8-2.5 degrees, and when the included angle is set, the support ring at one end is preferably semicircular, and the other end is integrally circular, so that the support body has a buffer effect on axial impact.

For the adjustment, a backing ring 9 is provided between the support ring 6 and the support body 5.
