Description

A cold rolling mill roll bearing seat block

technical field

The utility model relates to the field of machinery, in particular to a fixing device for a roll.

Background technique

At present, in order to achieve 6S management and safe and civilized production, the site is required to be clean and orderly. Since the surface of the intermediate roller body adopts the CVC curve shape, after the intermediate roller bearing seat is assembled with the journal, it needs to be hoisted to the ground in front of the roller changing car, and placed up and down in pairs. At the same time, spacers should be placed between the upper and lower roll bearing seats to prevent the contact between the upper and lower intermediate rolls, resulting in surface defects such as indentation, smearing, scratching, etc. The inspection and confirmation of the surface quality of the roll body is convenient to remove the plastic film packaging on the surface of the roll body, and the space in the roll preparation area can be effectively used.

The prior art does not provide a drawing of the chock block of the intermediate roller bearing seat, and only a long wooden square pad can be used between the upper and lower bearing seats during production. The long wooden squares used are not strong enough, often cracked and damaged, and the upper roller cannot be placed in a straight line with the lower roller when it is hoisted by a crane, and the operator needs to push and pull to straighten it. The invention aims to design a cushion block to solve the problem of skew placement of the upper and lower rolls, eliminate potential safety hazards, and realize essential safety.

SUMMARY OF THE INVENTION

In order to solve the above technical problems, the purpose of the present invention is to design a backing plate for the structure of the bearing seat, which can effectively fix the relative positions of the upper bearing seat and the lower bearing seat, and is suitable for hoisting. The specific technical solutions are as follows:

A cold rolling mill roll bearing seat cushion block includes an upper cushion plate and a lower cushion plate, the upper cushion plate and the lower cushion plate are both U-shaped, and the upper cushion plate is sleeved on the outer side of the convex part below the upper bearing seat and is in harmony with the upper cushion plate. The lower part of the upper bearing seat is in contact; the lower backing plate is sleeved on the outer side of the convex part below the lower bearing seat and abuts with the upper part of the lower bearing seat; The positioning pins correspond to the hoisting holes of the upper pad and the lower pad; both sides of the upper pad and the lower pad are respectively provided with an upper fixing part and a lower fixing part, and the positions of the upper fixing part and the lower fixing part are corresponding to and parallel to each other. A pin hole is provided, and the pin is inserted into the pin hole; the distance between the inner side of the lower backing plate groove and the side surface of the convex portion of the lower bearing seat is smaller than the distance between the inner side of the upper backing plate groove and the side surface of the convex portion of the upper bearing seat.

The inner sides of the opening ends of the grooves of the upper backing plate and the lower backing plate are inclined surfaces.

The difference between the outer diameter of the positioning pin of the upper backing plate and the inner diameter of the hoisting hole of the upper bearing seat is greater than the difference between the outer diameter of the positioning pin of the lower backing plate and the inner diameter of the lifting hole of the lower bearing seat.

The upper support plate includes a middle upper support plate and an upper top plate arranged at both ends of the upper support plate, and the upper support plate is a hollow structure; the lower support plate includes a middle lower support plate and a lower support plate arranged at both ends of the lower support plate. The top plate, the lower support plate is a hollow structure.

The advantages of the utility model are that it has the functions of axial and longitudinal positioning, prevents the upper and lower roller bearing seats from being skewed when they are placed, and is suitable for fixing the relative positions when the upper and lower roller bearing seats are hoisted at the same time.

Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings. As shown in the figure, a cold rolling mill roll chock block includes an upper backing plate 4 and a lower backing plate 5. The upper backing plate 4 and the lower backing plate 5 are both U-shaped, the upper backing plate 4 is fitted on the outer side of the raised portion 3 below the upper bearing seat 1 and abuts with the lower part of the upper bearing seat; the lower backing plate 5 is fitted on the outer side of the raised portion 3 under the lower bearing seat 2 and is in contact with the lower bearing The upper part of the seat is abutted; the grooves of the upper plate 4 and the lower plate 5 are provided with positioning pins 6, and the positioning pins 6 correspond to the hoisting holes 7 of the upper plate and the lower plate; the upper plate The upper fixing part 8 and the lower fixing part 9 are respectively provided on both sides of the plate 4 and the lower backing plate 5, the upper fixing part 8 and the lower fixing part 9 are located in corresponding positions and are provided with pin holes, and the pins 10 are inserted into the pin holes; The distance M between the inner side of the groove of the lower backing plate and the side surface of the convex portion of the lower bearing seat is smaller than the distance L between the inner side of the groove of the upper backing plate and the side surface of the convex portion of the upper bearing seat.

The inner side of the opening ends of the grooves of the upper backing plate and the lower backing plate are inclined surfaces 11 to facilitate positioning.

The difference between the outer diameter of the positioning pin of the upper backing plate and the inner diameter of the hoisting hole of the upper bearing seat is greater than the difference between the outer diameter of the positioning pin of the lower backing plate and the inner diameter of the lifting hole of the lower bearing seat.

The upper backing plate includes a middle upper supporting plate 40 and an upper top plate 41 arranged at both ends of the upper supporting plate. The upper supporting plate is a hollow structure of 40; The lower top plate 51 at both ends of the plate, and the lower support plate is a hollow structure 50 .
