Specifically, referring to fig. 3, the grinding and polishing mechanism 20 of the present embodiment further includes a bracket 23, a rotating arm 24, and a fourth driving motor 25; wherein, the bracket 23 is fixedly connected to the second slide carriage 32; a rotating shaft 241 rotatably connected with the top end of the bracket 23 is arranged in the middle of the rotating arm 24, the axial direction of the rotating shaft 241 is consistent with the sliding direction of the first sliding seat 31, a first worm wheel 242 is sleeved on the rotating shaft 241, and the two ends of the rotating arm 24 are respectively provided with a grinding assembly 21 and a polishing assembly 22; the fourth driving motor 25 is fixedly connected to the bracket 23, and an output shaft of the fourth driving motor 25 is connected to a first worm 251, and the first worm 251 is engaged with the first worm wheel 242.

The fourth driving motor 25 drives the first worm 251 to drive the first worm wheel 242 to rotate, thereby driving the rotating arm 24 to rotate through the rotating shaft 241 to switch the grinding state and the polishing state, and simultaneously, by utilizing the self-locking performance of the worm and gear transmission, the stability of the grinding state and the polishing state can be improved, thereby ensuring the grinding and polishing quality, and simultaneously, when the grinding and polishing machine 20 needs to move out of the length range of the roller body 63 during the laser texturing process, the rotating arm 24 can be rotated to the vertical state, thereby avoiding the interference or collision with peripheral components.

Illustratively, the grinding assembly 21 includes a first connecting seat 211 and a plurality of grinding bars 212, as shown in fig. 4, wherein the first connecting seat 211 is connected to one end of the rotating arm 24, and has a first arc surface matched with the diameter of the roll body 63, and a plurality of first inclined slots are distributed on the first arc surface at intervals along the axial direction of the rotating shaft 241; each of the grinding strips 212 is fitted into each of the first chutes, and each of the grinding strips 212 is attached to the roll body 63 in a grinding state.

For example, referring to fig. 3, the polishing assembly 22 includes a second connecting seat 221 and a plurality of polishing strips 222, wherein the second connecting seat 221 is connected to the other end of the rotating arm 24, and has a second arc surface matched with the diameter of the roller body 63, and a plurality of second inclined slots are distributed on the second arc surface at intervals along the axial direction of the rotating shaft 241; the polishing strips 222 are respectively correspondingly embedded in the second chutes, and the polishing strips 222 are attached to the roller body 63 in a polishing state.

Further, the range of the rotation range of the first connecting seat 211 and the second connecting seat 221 relative to the rotating arm 24 is within ten degrees, so as to ensure that the first arc surface and the second arc surface can face the roller body 63 when the grinding state and the polishing state are switched to each other, so that the second sliding seat 32 slides towards the roller body 63 to enable the abrasive strip 212 and the polishing strip 222 to be attached to the roller body 63, and the situation that the grinding state and the polishing state cannot be switched smoothly due to the fact that the free rotation angle of the first connecting seat 211 and the second connecting seat 221 is too large is avoided.

In this embodiment, the inclination angle of the grinding strips 212 is such that the horizontal distance generated at the two ends of the grinding strips 212 is greater than the horizontal distance between the adjacent grinding strips 212, so as to ensure that the adjacent grinding strips 212 are at least partially overlapped in the axial direction of the rotating shaft 241, thereby ensuring that the plurality of grinding strips 212 can form a continuous grinding surface, specifically, it can be understood that the rotation action of each grinding strip 212 in cooperation with the roller body 63 actually forms a spiral grinding working process, so as to ensure grinding consistency at any position of the roller body 63, and improve grinding quality.

Similarly, in the embodiment, the polishing strips 222 are inclined at an angle such that the horizontal distance generated between the two ends of the polishing strips 222 is greater than the horizontal distance between the adjacent polishing strips 222, so as to ensure that the adjacent polishing strips 222 at least partially overlap in the axial direction of the rotating shaft 241, thereby ensuring that a plurality of polishing strips 222 can form a continuous polishing surface, and improving the polishing quality.

Adopt the combination of a plurality of abrasive strips 212, polishing strip 222 to grind and polish and compare in the mode that conventional adoption abrasive disc and buffing wheel ground and polish, because the area of contact between bar-shaped structure and the roll body 63 is less, consequently can guarantee with the laminating degree between the roll body 63 to promote grinding and polishing effect, can directly take off after abrasive strip 212 or polishing strip 222 wear from first chute or second chute and trade new can again.

The operation steps of the positioning frame 40 in this embodiment are:

dismantling the detachable connection relationship between the pressing frame 42 and the bracket 41, specifically, unscrewing an operation screw 422 screwed with the bracket 41 on the pressing frame 42, and then turning the pressing frame 42 upwards for abdicating;

each first positioning hole 431 of the first positioning half ring 43 is pinned with the first positioning pin 412 on each rolling support 411, so that each rolling support 411 is connected into a whole through the first positioning half ring 43, and then the position of the second positioning half ring 44 is adjusted to drive each rolling support 411 to move adaptively until the two second positioning holes 432 on the first positioning half ring 43 are aligned with and pinned with the two second positioning pins 413;

after the above operations are completed on both brackets 41, the roll 60 is placed, and the roll necks 62 outside both ends of the roll body 63 are placed on the rolling supports 411 on both brackets 41, at this time, since the rolling supports 411 are positioned on the lower circular arc line 400 by the first positioning half ring 43, the rolling supports 411 can all collide with the roll necks 62, and on this basis, the inner annular surface of the first positioning half ring 43 should also be completely attached to the roll necks 62;

then, based on the purpose of determining the position reliability of the roll neck 62, verifying through the second positioning half ring 44, buckling the second positioning half ring 44 on one side of the first positioning half ring 43 on the roll neck 62, so that the inner ring surface of the second positioning half ring is attached to the upper half circumferential wall of the roll neck 62, then sliding the second positioning half ring 44 along the roll neck 62 towards the first positioning half ring 43, observing whether the second positioning half ring 44 and the first positioning half ring can be completely combined to form a complete ring, if no matching gap exists between the second positioning half ring and the roll neck 62, the roll neck 62 can be accurately positioned, each rolling support 411 and the bracket 41 can be directly and fixedly connected, if a gap exists between the second positioning half ring and the roll neck 62, the positioning of the roll neck 62 still has a deviation which is caused by the size error and the assembly gap of each rolling support 411, therefore, only the half rings from the rolling support 411 to the second positioning half ring 44 can be combined with the first positioning half ring 43 in a seamless manner when the deviation occurs, and then fixedly connecting each rolling support 411 and the bracket 41;

after the positioning adjustment is completed, the two positioning frames 40 are turned over again to reset the pressing frame 42 and fixed with the bracket 41, and after the fixing is completed, the output shaft of the first driving motor 13 and the pushing mechanism 14 are respectively connected with the two shaft heads 61, and certainly, in order to further confirm whether the circular runout meets the requirement, the connection can be completed and detected by using a dial indicator fixed on the laser 30 or the grinding and polishing machine 20 mechanism when the first driving motor 13 drives the roller 60 to rotate.

The two roll necks 62 are positioned, rolled and fixed by the two positioning frames 40, so that the difficulty of adjusting the fixed pose required by circular run-out in the fixing process of the roll 60 can be greatly reduced, and the distance between two points for positioning and fixing the roll 60 is reduced during adjustment, so that the fixing reliability of the roll 60 is improved; in addition, the first positioning half ring 43 and the second positioning half ring 44 which are different from each other are adopted, and the screw 50 is matched to adjust the distance between the two positioning frames 40, so that the installation and fixation of the rollers 60 with different sizes can be met, and the application range is improved.

The fifth driving motor 144 drives the second worm 145 to drive the second worm wheel 146 to rotate, so as to drive the rotating sleeve 141 to rotate, the rotating movement of the rotating sleeve 141 is converted into the axial telescopic movement of the telescopic sleeve 142 through the matching relationship between the internal thread and the external thread, so as to tightly push or release the spindle head 61 by the spindle 143, and the spindle 143 can rotate with the spindle head 61 when the first driving motor 13 drives the roller 60 to rotate, so as to ensure the connection stability of the spindle head 61.

It should be understood that in the present embodiment, each driving motor is preferably a servo motor or a stepping motor, so as to ensure the movement and control accuracy of each component, each action and the corresponding logic control all depend on the controller, and the specific control manner is the prior art, and will not be described in detail herein.

Based on the same inventive concept, the embodiment of the application also provides a stainless steel non-texture point-like surface processing method, which comprises the following steps:

the second secondary roller 60 for cogging rolling adopts a laser texturing roller with the roughness of 0.5-0.6 mu m to preliminarily eliminate the surface texture of the stainless steel band;

and (4) performing finished product rolling by using a working roller with a dot-shaped appearance, so that the dot-shaped appearance is copied on the surface of the stainless steel band with the surface texture preliminarily removed.

It should be noted that, in the method for processing a non-textured point surface of stainless steel provided in this embodiment, the existing parameters are adopted for the 60 passes and the rolling parameters of the roller in the whole rolling process, and an annealing process is also adopted between the cogging rolling process and the finished product rolling process, that is, the same two-rolling one-annealing process as the prior art is adopted, and the key point is to improve the surface treatment mode of the roller 60, so as to achieve the purpose of improving the surface quality of the stainless steel product.

In the process of implementing the invention, the inventor finds that the main factor of the gloss reduction of the stainless steel strip after the roller 60 is subjected to the conventional laser texturing treatment is that the roughness is increased due to the copying of the dotted shape on one hand, and the gloss of the roller body 63 of the roller 60 is insufficient on the other hand, so that the surface of the stainless steel strip generates higher gray scale.

In addition, it should be noted that, in the embodiment, since the laser texturing rollers of the last two passes are adopted to eliminate the original texture on the surface of the product in the cogging rolling process, compared with a later-stage method of eliminating the covering after the product is processed, the original texture is eliminated more completely.

Compared with the prior art, the stainless steel non-texture point surface processing method provided by the invention has the advantages that the stainless steel strip is rolled by using the laser texturing roller with the diameter of 0.5-0.6 mu m in the last two times of cogging rolling, the original texture on the surface of the stainless steel strip can be preliminarily eliminated, then the working roller which is sequentially subjected to grinding, polishing and laser texturing is adopted in the finished product rolling stage, and the working roller is polished and brightened before the laser texturing treatment and the original texture on the surface of the stainless steel strip is basically eliminated, so that the stainless steel strip product surface can form a regular point shape, the roughness of the product surface can be reduced, and the glossiness of the product surface is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
