Description

Technical Field

[0001] The present invention relates to the technical field of laser roll surface repair, and particularly to a local protection welding and nail replacement device for the roll surface of a stud roll press. Background Art

[0002] For a roll press, its roll sleeve mainly uses alloy structural high-strength steel as the base material, and is subjected to heat treatment and quenching and tempering treatment. Its roll surface is composed of drilled holes and stud nails embedded with metal adhesive.

[0003] Chinese Patent CN116765591A discloses a laser heating system, which includes: an upper control computer; a central control component, the central control component includes a plurality of repeaters connected in parallel to the upper control computer; multiple groups of intermediate modules, each group of intermediate modules includes a plurality of intermediate modules respectively connected to any one of the repeaters; multiple groups of laser modules, each group of laser modules includes a plurality of laser modules respectively connected to any one of the intermediate modules, and each laser module includes a number of laser emitters; wherein: the upper control computer is used to generate a control signal and send it to the repeater; each repeater is used to transmit the control signal to the intermediate module connected to it; each intermediate module transmits the control signal to the laser module connected to it; each laser module is used to drive the laser emitter connected to it to emit a laser beam under the control signal. The above laser heating system has high heating efficiency.

[0004] The following problems exist in the above patent and the prior art: During long-term use, the stud nails will break, so it is necessary to replace the broken nails. However, the existing nail replacement requires regional heating with a welding torch, and the heat-affected zone is relatively large. The adhesive strength and the strength of the nail body that do not need to be replaced nearby will be affected by heat and the strength will decrease, which will greatly affect the service life. Moreover, the gaps between adjacent stud nails will be filled with fine materials generated by roll pressing during long-term use, and then the gaps between adjacent stud nails on the roll sleeve surface will be filled, reducing the part of the stud nail exposed outside the roll sleeve. If the stud nail breaks into the filled residual materials at this time, it is not easy to take out the stud nail from the filled materials after heating the stud nail. And when the stud nail breaks in the roll sleeve, due to the blockage of the filled materials and the roll sleeve, it is even more difficult to take out the stud nail that has broken into the inside of the roll sleeve.

[0005] Therefore, heating the stud nails with a heating beam emitted by a laser welding generator or a laser generator to reduce the heat influence and replacing the stud nails at different positions meet the development needs of this industry. Summary of the Invention

[0015] As a preferred embodiment of the nail-changing device for local protection welding of the roll surface of the stud nail roll press according to the present invention, the following is provided: Movable wheels are installed at the bottom of the support base, the central shaft is connected through side plates, roll sleeves and the first inner lining column installed on its surface, the stud nails are embedded in the installation holes on the surface of the roll sleeve by gluing, and the installation holes penetrate through the roll sleeve. A number of installation grooves are annularly arranged along the contour of the surface of the first inner lining column, a clamping groove is arranged on the side of the installation groove, and a separation strip is arranged between the installation groove and the clamping groove; The stud nails pass through the roll sleeve and are inserted into the interior of the installation groove. There is a gap between the installation groove and the stud nails, and the end of the stud nail passing through the roll sleeve contacts the bottom of the installation groove. A convex strip is fixedly connected to the side of the roll sleeve opposite to the stud nails, and the convex strip is clamped in the interior of the clamping groove. A dividing block is arranged at the side end of the stud nail inside the roll sleeve.

[0016] As a preferred solution of the stud roller press roll surface partial protection welding nail-changing device described in the present invention, the following is provided: inner lining columns II are clamped inside the openings of the roll sleeves, and the connection mode of the inner lining columns II relative to the roll sleeves is the same as that of the inner lining columns I relative to the inner lining columns II.

[0017] Advantages of the present invention: 1. By the closed movement of the semi-ring parts, the broken and unbroken studs on the roll sleeve surface are taken out for replacement. The inner clamping parts rotate with the semi-ring parts to reduce the shielding effect of the material and the roll sleeve on the studs. At the same time, the threaded surface rotates and moves with the semi-ring parts to rotate and push the colloid inside the installation hole for cleaning, thereby improving the cleanliness of the next stud replacement and installation.

[0018] 2. The roll sleeve is clamped and connected with the inner lining column I through the convex strips, studs and dividing blocks and the card slots and installation grooves on the surface of the inner lining column I. Then, the side plates on the surface of the central shaft further seal the openings of the inner lining column I and the roll sleeve, thereby forming a detachable roll body. Furthermore, when the roll sleeve needs to be replaced, the fixation of the side plates relative to the roll sleeve and the inner lining column I is released, and the roll sleeve and the inner lining column I can be separated, thereby further reducing the cost of replacing the press roll. Only the roll sleeve needs to be replaced.

[0019] 3. After the centers of the two semi-ring parts correspond to the center of the stud to be replaced, the first push driving source and the second push driving source are synchronously started under the control of the encoder and the PLC. The output shafts of the first push driving source and the second push driving source move towards the roll sleeve synchronously. Then, the cross plates I and II at the front ends of the first push driving source and the second push driving source drive the semi-ring parts on their sides close to the roll sleeve to move towards the surface of the roll sleeve. During this process, the rotation driving source is started, and the rotation driving source drives the rotating plate to rotate around the stud to be replaced. When the rotating plate rotates, the first push driving source and the second push driving source on the side of the rotating plate rotate synchronously, and the pointed tooth blocks at the front end of the semi-ring part rotate accordingly. Furthermore, as the first push driving source and the second push driving source push the semi-ring parts, the pointed tooth blocks at the front end of the semi-ring part rotate around the stud during the rotation of the semi-ring part, thereby grinding the filling material accumulated on the side of the stud on the roll sleeve surface. Then, the densely filled material on the side of the stud is continuously ground, and the densely packed state of the material is broken up, so that the stud leaks out from the surface of the roll sleeve.

[0020] Fourth, a spiral heating path is formed by moving up and down in combination with rotation, so that the column nail to be replaced is heated more evenly, so that the colloid connecting the column nail and the roller sleeve is heated, melted and invalidated. At the same time, the spiral heating path avoids excessive heat transfer from one side of the column nail to be replaced to the roller sleeve due to a single heating area, thereby causing local thermal damage to the surface of the roller sleeve, and also avoids the roller sleeve from excessively transferring heat to other non-replaced column nails, further causing damage to other column nails. The spiral heating path formed by the up and down movement combined with rotation improves the heating efficiency, so that the glue layer of the metal adhesive can reach the melting temperature and invalidate in a shorter time, reducing the time window for heat to be lost to the roller sleeve surface through radiation and convection.

[0021] 5. Start the expansion and closing driving source, so that the expansion and closing driving source drives the driving wheel to rotate, so that the driving wheel drives the driven bars 1 and 2 to approach the center of the expansion and closing driving source, and then the driven bars 1 and 2 drive the push driving source 1 and the push driving source 2 to move toward the middle of the expansion and closing driving source, and then the semi-ring parts at the bottom of the push driving source 1 and the push driving source 2 move relatively, so that the two semi-ring parts are clamped to the surface of the column nail, so that the column nail is clamped, and then the push driving source 1 and the push driving source 2 drive the semi-ring parts and the column nail clamped by the semi-ring parts to withdraw, so that the column nail is pulled out from the surface of the roller sleeve, and then the rotating driving source is synchronously started during the pulling out process, so that the semi-ring parts drive the clamped column nail to rotate, thereby completing the rotation and pulling out of the column nail, improving the separation effect of the column nail and the mounting hole on the surface of the roller sleeve, and then facilitating subsequent replacement.

[0022] 6. The two semi-rings are moved toward each other under the drive of the expansion and closing driving source, so that the two semi-rings are closed, and are inserted into the mounting hole corresponding to the inside of the roller sleeve of the column to be replaced under the synchronous push of the push driving source 1 and the push driving source 2, and gradually extend to the bottom of the mounting hole. After reaching the preset distance, the rotation driving source is started, so that the rotation driving source drives the semi-ring to rotate inside the mounting hole. When the semi-ring rotates, the threaded surface on its surface will also continuously stir the failed colloid on the inner surface of the mounting hole, and the push driving source 1 and the push driving source 2 synchronously drive the rotating semi-ring and the threaded surface to move outward, thereby completing the cleaning of the inside of the mounting hole, thereby reducing the residual colloid inside the mounting hole, thereby improving the connection firmness of the subsequent installation and replacement of the column, and the above process can be repeated many times, thereby further improving the cleanliness of the inside of the mounting hole.

[0023] VII. Heat the outer surface of the stud in the mounting hole with the laser generating component, so that the colloid is heated and fails to conduct heat through the stud. After the heating is completed, control the first pushing driving source and the second pushing driving source to make the half-ring component and the inner clamping component reciprocally impact the area of the mounting hole of the stud located on the surface of the roller sleeve, so as to further improve the separation degree of the stud and the mounting hole through vibration. Then, make the half-ring component retreat away from the roller sleeve, make the driven wheel rotate driven by an external motor and a belt, make the roller sleeve rotate driven by the central shaft and the driven wheel, make the mounting hole of the broken stud be driven to the bottom of the roller sleeve, and make the mounting hole of the broken stud be perpendicular to the ground downward, so as to facilitate the broken stud to be discharged under gravity through the mounting hole.

[0024] VIII. After the heating is completed, control the driving source for opening and closing to make the driving wheel rotate, make the driving wheel drive the first driven strip and the second driven strip to move towards the center of the driving source for opening and closing, and then make the half-ring component close. At this time, the diameter of the half-ring component after closing is smaller than the diameter of the mounting hole on the surface of the roller sleeve. Then, synchronously start the second pushing driving source and the first pushing driving source, make the first pushing driving source and the second pushing driving source push the half-ring component into the inside of the mounting hole, and synchronously start the rotating driving source to make the half-ring component rotate forward inside the mounting hole. Then, on the basis that the colloid between the stud and the mounting hole is heated and fails, the broken stud inside the mounting hole is rotated and pushed into the inside of the roller sleeve by the half-ring component, and the residual ineffective colloid is also pushed into the inside of the roller sleeve, so as to realize the internal pushing and extraction of the broken stud and the rotating pushing and cleaning of the residual colloid inside the mounting hole.

[0039] Operation process: For large stud roller presses or small and medium-sized roller presses where the stud 1031 has not broken inside the roller sleeve 103: By moving the mounting frame 201 to the side of the roller sleeve 103, for a large roller press, the first inner lining column 105 and the roller sleeve 103 are not disassembled under non-essential circumstances after being fixed by the side plate 102, unless the roller sleeve 103 is replaced as a whole or there are a large number of studs 1031 broken inside its mounting holes on the surface of the roller sleeve 103 to be repaired. Therefore, the roller sleeve 103 is clamped and connected with the card slots 1052 and mounting grooves 1051 on the surface of the first inner lining column 105 through the ribs 1032, studs 1031 and split blocks 1033. Then, the side plate 102 on the surface of the central shaft 104 further seals the openings of the first inner lining column 105 and the roller sleeve 103, thus forming a detachable roller body. Furthermore, when the roller sleeve 103 needs to be replaced, the fixing of the side plate 102 relative to the roller sleeve 103 and the first inner lining column 105 is released, and the roller sleeve 103 and the first inner lining column 105 can be separated, thereby further reducing the cost of replacing the press roller. Only the roller sleeve 103 needs to be replaced; When a single stud 1031 to be replaced on the surface of the roller sleeve 103 needs to be separated from the roller sleeve 103, the centers of the two half-ring members 209 are aligned with the center of the stud 1031 to be replaced; It should be noted that to align the centers of the two half-ring members 209 with the stud 1031 to be replaced, this alignment can be achieved by installing a vision camera on the surface of the mounting plate 2031, identifying the position of the stud 1031 through the camera, then calculating the physical coordinates through coordinate transformation, and controlling the moving drive source 2021 to drive the drive base 203 and the mounting plate 2031 on the ball screw in the moving rod 202 to move to the side of the stud 1031 to be replaced, so that the centers of the two half-ring members 209 are aligned with the center of the stud 1031 to be replaced. Or directly manually control the rotation of the moving drive source 2021, so that the moving drive source 2021 drives the ball screw in the moving rod 202 to rotate, thereby adjusting the positions of the drive base 203 and the mounting plate 2031. Then, under manual recognition and alignment, the centers of the two half-ring members 209 are aligned with the stud 1031 to be replaced.

[0040] After aligning the centers of the two semi-ring members 209 with the center of the stud 1031 to be replaced, the driving source one 2056 and the driving source two 2057 are synchronously started under the control of the encoder and the PLC, so that the output shafts of the driving source one 2056 and the driving source two 2057 approach the roller sleeve 103 synchronously. Further, the cross plates one 20561 and two 20571 at the front ends of the driving source one 2056 and the driving source two 2057 drive the semi-ring members 209 on the side close to the roller sleeve 103 to move towards the surface of the roller sleeve 103. During this process, the rotation driving source 204 is started, so that the rotation driving source 204 drives the rotation plate 2041 to rotate around the stud 1031 to be replaced. When the rotation plate 2041 rotates, the driving source one 2056 and the driving source two 2057 on the side of the rotation plate 2041 will rotate synchronously, causing the pointed tooth blocks 2093 at the front ends of the semi-ring members 209 to rotate accordingly. Further, as the driving source one 2056 and the driving source two 2057 push the semi-ring members 209, the pointed tooth blocks 2093 at the front ends of the semi-ring members 209 rotate around the stud 1031 continuously while the semi-ring members 209 rotate, so as to polish the filling material accumulated on the surface of the roller sleeve 103 on the side of the stud 1031. Further, the densely filled material on the side of the stud 1031 is continuously polished, so that the densely packed state of the material is broken up, and then the stud 1031 leaks out from the surface of the roller sleeve 103. Further, when the driving source one 2056 and the driving source two 2057 move to a preset distance, the stud 1031 will be leaked out under the rotation of the pointed tooth block 2093 around the stud 1031; Then, start the laser generating component 2062 again to heat the stud 1031 with the beam of the laser generating component 2062. During the process of heating the stud 1031 by the laser generating component 2062, continue to start the rotation drive source 204 to drive the rotating plate 2041 and the laser generating component 2062 to rotate around the stud 1031 to be replaced, so that the laser generating component 2062 heats the stud 1031 in a circular manner. And start the reciprocating drive source 206 to drive the laser generating component 2062 to move up and down linearly along the stud 1031, which is convenient for the stud 1031 to transfer heat to the colloid. The range of the up and down movement is preferably near the connection between the stud 1031 and the mounting hole, so that the heating beam emitted by the laser generating component 2062 can more easily transfer heat to the colloid through the stud 1031. Then, by combining the up and down movement with rotation to form a spiral heating path, the stud 1031 to be replaced is heated more evenly, so that the colloid connecting the stud 1031 and the roller sleeve 103 is heated and melted and fails. At the same time, the spiral heating path avoids the excessive transfer of heat from a single side of the stud 1031 to be replaced to the roller sleeve 103 due to a single heating area, so as to avoid local thermal damage to the surface of the roller sleeve 103, and also avoids the roller sleeve 103 from transferring excessive heat to other non-replaced studs 1031, further causing damage to other studs 1031. Moreover, the spiral heating path formed by combining the up and down movement with rotation improves the heating efficiency, enables the adhesive layer of the metal adhesive to reach the melting temperature and fail in a shorter time, and reduces the time window for heat to be dissipated to the surface of the roller sleeve 103 through radiation and convection.

[0041] Of course, in order to further reduce the shielding of the stud 1031 by the densely packed materials on the side of the stud 1031 to be replaced, after the inner clamping member 2091 finishes cleaning and rotating the outside of the stud 1031, the pushing drive source one 2056 and the pushing drive source two 2057 drive the half-ring member 209 to lift and retreat between the emission end of the laser generating component 2062 and the folding plate 2061, so that the laser generating component 2062 heats the stud 1031 and reduces the blockage of the beam emitted by the laser generating component 2062 by the half-ring member 209.

[0042] When the laser generating component 2062 stops after heating the stud 1031 to be replaced for a preset time, at this time, the half-ring member 209 is not in contact with the stud 1031 and there is a gap between them. The gap does not exceed 0.2 cm, and the two semi-circular hollow sleeves 207 at the top of the half-ring member 209 are located at the outer top of the stud 1031 to be replaced, and the two semi-circular hollow sleeves 207 block the top of the stud 1031 to be replaced, reducing the situation of the stud 1031 being ejected after being heated and hitting people or equipment, and improving the safety of replacing the stud 1031; Then, the expansion and closing driving source 205 is started, so that the expansion and closing driving source 205 drives the driving wheel 2053 to rotate, so that the driving wheel 2053 drives the driven bar 1 2054 and the driven bar 2055 to approach the center of the expansion and closing driving source 205, and then the driven bar 1 2054 and the driven bar 2055 drive the push driving source 1 2056 and the push driving source 2 2057 to move toward the middle of the expansion and closing driving source 205, and then the semi-ring member 209 at the bottom of the push driving source 1 2056 and the push driving source 2 2057 moves relative to each other, so that the two semi-ring members 209 are clamped to the surface of the column nail 1031, so that the column nail 1031 is clamped, and then the push driving source 1 2056 and the push driving source 2 2057 are clamped. The second driving source 2057 drives the semi-ring member 209 and the column nail 1031 clamped by the semi-ring member 209 to withdraw, so that the column nail 1031 is pulled out from the surface of the roller sleeve 103, and then the rotating driving source 204 is synchronously started during the pulling out process, so that the semi-ring member 209 drives the clamped column nail 1031 to rotate, thereby completing the rotational pulling out of the column nail 1031, improving the separation effect of the column nail 1031 and the mounting hole on the surface of the roller sleeve 103, and thus facilitating subsequent replacement; and when replacing, the new column nail 1031 can also be inserted into the mounting hole on the surface of the roller sleeve 103 after being clamped by the semi-ring member 209, so that the pre-applied glue on the surface of the column nail 1031 is dispersed between the column nail 1031 and the mounting hole.

[0043] When the column nail 1031 is pulled out, the semi-ring member 209 drives the clamped column nail 1031 to the outside of the roller sleeve 103 and then expands, so that the column nail 1031 inside the semi-ring member 209 is expanded and falls, and then the two semi-ring members 209 are driven by the expansion and closing driving source 205 to move toward each other, so that the two semi-ring members 209 are closed, and are inserted into the mounting hole corresponding to the roller sleeve 103 of the column nail 1031 to be replaced under the synchronous driving of the driving source 1 2056 and the driving source 2 2057, and gradually extend to the bottom of the mounting hole. After reaching the preset distance, the rotation driving source 204 is started to rotate. The rotary drive source 204 drives the semi-ring member 209 to rotate inside the mounting hole. When the semi-ring member 209 rotates, the threaded surface 2092 on its surface will continuously stir the failed colloid on the inner surface of the mounting hole, and the push drive source 1 2056 and the push drive source 2 2057 will synchronously drive the rotating semi-ring member 209 and the threaded surface 2092 to move outward, thereby completing the cleaning of the inside of the mounting hole, thereby reducing the residual colloid inside the mounting hole, thereby improving the connection firmness of the subsequent installation and replacement of the column nail 1031, and the above process can be repeated multiple times, thereby further improving the cleanliness of the inside of the mounting hole.

[0044] For the stud 1031 whose fracture is inside the mounting hole of the roll sleeve 103, the laser generating part 2062 heats the outer surface of the stud 1031 in the mounting hole, so that the colloid is heated and fails by conduction through the stud 1031. After the heating is completed, the pushing drive source one 2056 and the pushing drive source two 2057 control the half-ring part 209 and the inner clamping part 2091 to reciprocally impact the area of the mounting hole corresponding to the stud 1031 on the surface of the roll sleeve 103, so as to further improve the separation degree between the stud 1031 and the mounting hole through vibration. Then, the half-ring part 209 retreats away from the roll sleeve 103, the driven wheel 106 is driven to rotate by an external motor and a belt, the roll sleeve 103 is driven to rotate by the central shaft 104 and the driven wheel 106, the mounting hole of the fractured stud 1031 is driven to the bottom of the roll sleeve 103, and the mounting hole of the fractured stud 1031 is perpendicular to the ground downward, which is convenient for the fractured stud 1031 to be discharged under gravity from the mounting hole.

[0045] After one stud 1031 on the surface of the roll sleeve 103 is disassembled, the central shaft 104 is driven to rotate by the driven wheel 106, and combined with the movement of the driving base 203, the stud 1031 on the surface of the next roll sleeve 103 that needs to be disassembled and replaced is heated and disassembled. Embodiment 2:

[0046] Operation process: For a medium and small-sized stud roll press or a large-sized roll press with too many studs 1031 fractured inside the mounting holes on the surface of the roll sleeve 103: By disassembling the side plates 102 on both sides of the roll sleeve 103 and the inner lining stud one 105, the roll sleeve 103 is separated from the surface of the inner lining stud one 105. Two inner lining studs two 107 are clamped to both sides of the opening of the roll sleeve 103, the central shaft 104 is installed in the middle of the inner lining stud two 107, the middle part of the side plate 102 is bolted to the surface of the central shaft 104, and the side parts of the side plate 102 are bolted to the inner lining stud two 107 and the roll sleeve 103 respectively. Thus, when the driven wheel 106 on the side of the central shaft 104 is driven to rotate by an external motor, the central shaft 104, the roll sleeve 103 and the inner lining stud two 107 can be driven to rotate synchronously. At this time, the position of the stud 1031 corresponding to the inside of the roll sleeve 103 is not blocked by the inner lining stud two 107; For the column nail 1031 that is broken inside the mounting hole on the surface of the roller sleeve 103, the roller sleeve 103 is rotated and cooperated with the movement of the driving base 203, so that the center of the connection line of the two half rings 209 on the side of the driving base 203 corresponds to the center of the broken column nail 1031, and the reciprocating driving source 206 pushes the laser generating element 2062 to move, so that the laser generating element 2062 heats the outer surface of the column nail 1031 inside the mounting hole. For the column nail 1031 that is broken too deeply, it is necessary to rotate the roller sleeve 103 so that the laser generating element 2062 heats the connection between the column nail 1031 and the mounting hole of the roller sleeve 103, or adjust the laser generating element 2062 to be installed on the folding plate 2061 at the middle position of the four auxiliary rods 2051, so that the light beam of the laser generating element 2062 directly hits the column nail 1031, and then the column nail 1031 is heated at a fixed point, so that the colloid is ineffective due to the conduction heating of the column nail 1031; After the heating is completed, the expansion and closing driving source 205 controls the driving wheel 2053 to rotate, so that the driving wheel 2053 drives the driven bar 1 2054 and the driven bar 2055 to move toward the center of the expansion and closing driving source 205, thereby closing the semi-ring member 209. At this time, the diameter of the semi-ring member 209 after closing is smaller than the diameter of the mounting hole on the surface of the roller sleeve 103, and then the pushing driving source 2 2057 and the pushing driving source 1 2056 are started synchronously, so that the pushing driving source 1 2056 and the pushing driving source 2 2057 push the semi-ring member 209 into the interior of the mounting hole, and the rotating driving source 204 is started synchronously, so that the semi-ring member 209 rotates and advances inside the mounting hole, and then on the basis of the column nail 1031 and the colloid of the mounting hole being heated and invalidated, the broken column nail 1031 inside the mounting hole is rotated and pushed into the interior of the roller sleeve 103 by the semi-ring member 209 from the interior of the mounting hole, and the invalid residual colloid is also pushed into the interior of the roller sleeve 103, thereby achieving the broken column nail 1031. The nail 1031 is pushed inward and removed, and the residual colloid inside the mounting hole is cleaned by rotation. Then, when the broken column nails 1031 on the surface of the roller sleeve 103 are all pushed inward into the roller sleeve 103, the side plate 102 and the inner lining column 107 are opened, and the inside of the roller sleeve 103 is cleaned uniformly. Then, in combination with the operation process of Example 1 and Example 2, the broken and unbroken column nails 1031 on the surface of the roller sleeve 103 are removed for replacement through the closing movement of the semi-ring member 209, and the inner clamping member 2091 rotates with the semi-ring member 209 to reduce the blocking effect of the material and the roller sleeve 103 on the column nail 1031. At the same time, the threaded surface 2092 rotates with the semi-ring member 209 to also realize rotation and push cleaning of the colloid inside the mounting hole, thereby improving the neatness of the next replacement and installation of the column nail 1031. The above process is also a supplementary solution for the broken column nail 1031 that was not knocked out by the semi-ring member 209 and the inner clamping member 2091 during the operation of Example 1.
