Description
Technical Field
The utility model relates to a backing roll, in particular to conveniently change backing roll of shoulder ring.
Background
The main working parts and tools on the rolling mill produce continuous plastic deformation of the metal. The support rollers are essentially the support rollers that support the work rolls and reduce the diameter of the work rolls and increase the stiffness of the work rolls by contacting the work rolls with the product to be rolled. Back-up rolls are important parts in rolling mills to back up work or intermediate rolls in case of deflection of the work rolls affecting the yield and quality of the plate or strip. The quality characteristics of the supporting roll are that the surface hardness of the roll body is high, the uniformity of the hardness is good, the hardening layer of the roll body is deep, and the roll neck and the core of the roll body have good obdurability; the quality characteristics of the supporting roller are high wear resistance, good peeling resistance and strong accident resistance.
The use of present backing roll is very extensive, but current backing roll generally directly the processing of turning out on the support roll body is accomplished, changes comparatively frequently when wearing and tearing are great, has not only reduced production efficiency, has improved manufacturing cost moreover, sometimes only when the shoulder ring wearing and tearing or damage, need change whole backing roll, has improved use cost by a wide margin moreover.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a backing roll of conveniently changing shoulder ring.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to a supporting roller convenient for replacing a shoulder ring, which comprises a main body part, wherein,
mounting holes are distributed at the end part of the main body part;
the main body part is connected or fixed with a shoulder ring through a fixing device, wherein,
through holes are distributed on the shoulder ring;
the surface of the shoulder ring is covered with a protective layer.
As a preferable technical proposal of the utility model, the two end parts of the main body part are provided with installation parts, wherein,
the mounting portion penetrates through the through groove of the shoulder ring.
As an optimized technical solution of the present invention, the fixing device is a bolt.
As a preferred technical solution of the present invention, the number of the mounting holes is the same as that of the through holes;
the diameter of the through groove is larger than or equal to that of the mounting part;
the shoulder ring has a diameter smaller than a diameter of the body portion.
The utility model discloses the beneficial effect who reaches is: the shoulder ring of the support roll (composed of the main body part, the mounting part and the shoulder ring) can be conveniently mounted and dismounted through the fixing device, when the shoulder ring is worn or damaged, the shoulder ring can be conveniently replaced, the influence on the production efficiency and the use efficiency is avoided, and the use cost and the production cost are reduced; the protective layer covers the surface of the shoulder ring, so that the shoulder ring is better protected, and the service life of the shoulder ring is prolonged.

in the figure: 1. a main body portion; 101. mounting holes; 2. an installation part; 3. a shoulder ring; 301. a through hole; 302. a through groove; 4. and (4) a fixing device.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Examples
As shown in fig. 1-3, the utility model provides a support roller convenient for replacing shoulder rings, which comprises a main body part 1, wherein mounting holes 101 are distributed at the end part of the main body part 1; the main body part 1 is connected or fixed with a shoulder ring 3 through a fixing device 4, wherein through holes 301 are distributed on the shoulder ring 3; the mounting hole 101 corresponds to the through hole 301, so that the fixing device 4 can pass through the mounting hole 101 and the through hole 301 to fix the main body 1 and the shoulder ring 3.
The surface of the shoulder ring 3 is covered with a protective layer, such as a ceramic layer wrapping mode.
Further, the two ends of the main body 1 are provided with mounting portions 2, wherein the mounting portions 2 penetrate through the through grooves 302 of the shoulder ring 3 to facilitate the fixing or connection between the shoulder ring 3 and the main body 1.
Specifically, the fixing device 4 is a bolt, and other forms can be selected; the number of the mounting holes 101 is the same as that of the through holes 301, and other forms can be selected according to requirements;
the diameter of the through groove 302 is larger than or equal to that of the mounting part 2, so that the through groove can be produced conveniently as required;
the diameter of the shoulder ring 3 is smaller than that of the main body part 1, and the shoulder ring 3 is fixed with the main body part 1 through a fixing device 4 (bolt), so that abrasion or wear-out is avoided.
The shoulder ring of the support roll (composed of the main body part, the mounting part and the shoulder ring) can be conveniently mounted and dismounted through the fixing device, when the shoulder ring is worn or damaged, the shoulder ring can be conveniently replaced, the influence on the production efficiency and the use efficiency is avoided, and the use cost and the production cost are reduced; the protective layer covers the surface of the shoulder ring, so that the shoulder ring is better protected, and the service life of the shoulder ring is prolonged. The shoulder ring is used for water sealing and oil sealing to prevent water, oil and the like from entering the bearing seat.
