Description of the embodiments

In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions according to the embodiments of the present invention will be clearly described in the following with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 5, an embodiment of the present invention provides a method for processing a wide plate ring, including:

step 40: welding the butt joint of the standard circular rings;

In the processing method in the embodiment, the processing of the circular ring for installing the slewing bearing is realized in a rolling way, compared with the processing technology in the prior art, the manufacturing difficulty and the manufacturing cost can be reduced, in addition, the bending sections are respectively arranged at the two ends of the rectangular long strip-shaped wide plate, and the processing precision can be improved.

Specifically, the wide plate is contracted during the rolling process, and therefore, it is necessary to provide curved sections at both ends of the wide plate, respectively.

In a further implementation of this embodiment, in step 30, the wide plate is wound into a standard circular ring by a rounder.

In the embodiment, the wide plate is wound into the standard ring through the rounding machine, so that the rounding precision and the processing efficiency can be improved.

In a further embodiment of the present example, in step 20, bending sections are provided at both ends of the wide plate by means of pre-bending.

Specifically, after the blanking is completed, bending sections are arranged at two ends of the wide plate in a bending mode.

In a further embodiment of the present embodiment, in step 20, the bending sections are provided by cutting at both ends of the wide plate during blanking.

In this embodiment, the curved section may also be formed by direct cutting during the blanking process.

In the cutting process, the accuracy of cutting and blanking (the straightness of the length direction of the plate) and the perpendicularity of a cutting surface are required to be ensured, and if the straightness of the plate is poor, uneven stress can be generated when the plate is coiled, so that roundness error after coiling is caused; if the cutting surface has poor perpendicularity, the distortion of the rolling piece is serious.

In a further implementation of this embodiment, the rolling machine specifically includes two fixed wheels 100 and one moving wheel 200, the two fixed wheels 100 are located on the first side, the one moving wheel 200 is located on the other side, and the moving wheel 200 is located between the two fixed wheels 100, the moving wheel 200 can move towards the direction close to the fixed wheels 100 and away from the fixed wheels 100, during the rolling process, a wide plate is disposed between the fixed wheels 100 and the moving wheel 200, and the two fixed wheels 100 and the moving wheel 200 rotate and the rotation directions are opposite to each other for rolling the wide plate.

In a further implementation of this embodiment, the driving wheel 200 is disposed at an intermediate position between the two fixed wheels 100.

In a further implementation of this embodiment, the pressing force of the driving wheel 200 on the wide plate is adjusted by adjusting the position of the driving wheel 200 during the rolling process.

In a further implementation of this embodiment, the driving wheel 200 drives the adjusting wheel through the oil cylinder 100.

In a further implementation of this embodiment, in step 20, the bending position of the bending section is 300mm-400mm near both ends of the wide plate.

The pre-bending length is 300-400mm, the pre-bending length is determined according to the center lines of two fixed wheels of the round rolling flange machine, the pre-bending length is larger than the center distance of the wheels, the support effect is achieved, the forming is convenient, the upturned arc at the end part plays the pre-bending effect, the bending property is directly cut out by a numerical control flame cutting machine during blanking, if the numerical control plasma cutting machine is used for blanking, the verticality of a cutting surface is poor, the distortion of a circular ring is extremely easy to be caused, the grinding and shaping are needed before the round rolling, and the working procedure and the cost are increased.

In a further implementation manner of this embodiment, in step 10, compensation is performed based on the set size of the wide plate ring to obtain a rectangular long wide plate size.

Considering that the two sides of the wide plate form extrusion to the workpiece during rolling forming, the thickness dimension can be reduced after rolling forming, and the thickness dimension compensation is performed during blanking according to the comprehensive calculation of the strength, the plate thickness and the bandwidth of the material, namely the blanking thickness dimension is larger than the design thickness requirement.

In addition, the technical scheme has the advantages that: 8 welding seams (4 double sides) and 16 grooves are needed in conventional production, and the processing method only has 2 welding seams (1 double sides) and 4 grooves, so that the welding time, the welding wire cost, the groove processing time and the gas cost are saved;

the utilization rate of the material for blanking is improved to more than 80% from 60% -65% originally, so that the material cost is saved;

during conventional production welding, 32 arc striking plates and arc receiving plates are needed, and the production mode of the processing method only needs 8 arc striking plates and arc receiving plates, so that auxiliary materials are saved, and cutting and polishing time and cost are saved.

Along with the reduction of the welding seams, the cracking risk of the welding seams caused by stress is avoided, and the quality of finished products is improved.
