[0010] , ,

[0001] The present invention relates to the technical field of furnace tube grinding, and particularly to a grinding device for external convex rib fins of a superalloy furnace tube. Background Art

[0002] A superalloy furnace tube is a pipe made of superalloy material, which can transfer heat from a heat source to the material or reaction medium to be heated. Special structures are usually designed on the outer side of the furnace tube to increase the heat transfer area. For example, spiral convex rib fins are designed on the outer side of the furnace tube to make the heat evenly distributed on the surface of the furnace tube. The external convex rib fins are often formed by casting or welding processes, and the surface roughness is relatively high. For furnace tubes used at high temperatures for a long time, oxide scales and impurities are likely to form on the surface of the tube body and the fins. In order to remove burrs, oxide scales and impurities, a grinding device is needed to grind and polish the furnace tube.

[0003] At present, most grinding devices mainly drive the furnace tube to rotate through a motor, and the grinding brush roller feeds along the axial direction of the furnace tube to achieve continuous grinding of the furnace tube surface. However, such grinding devices are mainly applicable to regular cylindrical surfaces and are not conducive to processing the complex spiral curved surfaces of the external convex rib fins, thus affecting the grinding effect of the furnace tube fins. In order to prevent high temperatures generated by dry grinding from causing microcracks in the material, coolants are often added to the furnace tube during the grinding process. However, most of the structures for adding coolants are independently designed and are not conducive to combining with the grinding structure of the furnace tube to save coolants while optimizing the overall efficiency of grinding and cooling. Summary of the Invention

[0014] Furthermore, a cylinder is fixed on the top surface of the base, and an output end of the cylinder is fixedly connected to the carrying box.

[0015] Furthermore, the telescopic part includes a sleeve rotatably connected to the support plate, a sliding rod is slidably engaged with the bottom of the sleeve, the sliding rod is fixedly connected to the grinding brush roller, and a motor 2 that can drive the sleeve to rotate is fixed on the top surface of the support plate.

[0016] Furthermore, the driving mechanism further includes two columns both fixedly connected to the base, the screw rods are rotatably connected to the columns, and a motor three capable of driving the screw rod to rotate is fixed to the top of one of the columns.

[0017] Furthermore, one end of the injection cylinder is slidably connected to a piston rod, one end of the piston rod is fixedly connected to the carrier box, the arc tube is fixedly connected to the telescopic member, and two water outlet holes are provided at the bottom of the arc tube.

[0018] Furthermore, the clamp includes a support tube rotatably connected to a support seat, a gear and a rotating block are fixed to one end of the support tube, and an adjusting rod capable of abutting and fixing the furnace tube from the inside of the furnace tube is provided inside the support tube.

[0019] Furthermore, the adjusting rod includes a connecting column, both ends of the connecting column are provided with studs screwed together with the support tube, one end of the stud is fixed with a frustum block, and one end of the stud is fixed with a rotating tube rotatably connected to the support tube.

[0020] Furthermore, a plurality of movable blocks are evenly abutted and slidably provided on the outer side of the truncated cone block, an arc-shaped plate is fixed between two of the movable blocks, and the movable blocks are slidably engaged with the support tube.

[0021] Furthermore, the two gears 1 are meshed for transmission, and a gear 2 meshed with the gear 1 for transmission is fixed to the output end of the motor 1.

[0022] Furthermore, the outer side of the gear 1 is meshed with a grinding brush roller 2, the middle part of the grinding brush roller 2 is plugged and fixed with a shaft, and the two ends of the shaft are respectively rotatably connected to the support seat 1 and the support seat 2.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. A support base 1 and a support base 2 are fixed on both ends of the carrier box and are slidably connected. A clamp is provided on the top of the support base 1. The support base 2 is moved in a direction away from the support base 1, one end of the furnace tube is sleeved on the clamp, and the clamp fixes the furnace tube from the inside of one end of the furnace tube. The support base 2 is moved in a direction close to the support base 1, so that the furnace tube is rotated and installed between the support base 1 and the support base 2. The telescopic member is extended to insert the grinding brush roller 1 into the gap position between the two spiral ribs of the furnace tube. The motor 2 drives the telescopic member to rotate the grinding brush roller 1, so that the outer side of the fin and the outer side of the furnace tube that can contact the grinding brush roller 1 can be easily ground.

[0025] The motor 1 drives the two gears 1 to rotate synchronously in the opposite direction through the gear 2, so that the two furnace tubes rotate in the direction away from the grinding brush roller 1. At this time, the spiral fins on the two furnace tubes will drive the grinding brush roller 1 to move to the right. In order to prevent the grinding brush roller 1 from moving and to grind different areas of the outside of the furnace tube and different areas of the fins, when the furnace tube rotates in the direction away from the grinding brush roller 1, the two furnace tubes on the carrier box can be moved to the right at the same time through the output end of the cylinder, so that the grinding brush roller 1 remains relatively stationary with the furnace tube during the rotation of the furnace tube, so that the grinding brush roller 1 can perform all-round grinding of different areas of the outside of the furnace tube and different areas of the outside of the fins during the rotation of the furnace tube.

[0026] After the furnace tube rotates outwards one circle (rotation in the direction away from the grinding brush roller 1 is recorded as outward rotation, and rotation in the direction close to the grinding brush roller 1 is recorded as inward rotation), the motor 1 can be made to drive the two furnace tubes to rotate inwards one circle. At this time, the fins on the two furnace tubes will cause the grinding brush roller 1 to move left. In order to prevent the grinding brush roller 1 from moving and continue to repeatedly grind different areas of the outside of the furnace tube and different areas of the fins, when the furnace tube rotates inwards, the two furnace tubes on the carrier box can be moved to the left at the same time through the output end of the cylinder, and the carrier box can return to the initial position. Similarly, the grinding brush roller 1, which remains relatively stationary with the furnace tube, can perform a second all-round grinding on the outside of the inwardly rotating furnace tube and the outside of the fins.

[0027] Abrasive brush roller is located in a gap between the two furnace tubes (refer to the gap position). Figure 10) After stopping and rotating for a period of time, the two furnace tubes can continue to rotate outward for one circle with the fins, and the rotating spiral fins will convey the grinding brush roller. This process keeps the carrier box stationary. During this process, the motor drives the screw to rotate, and the grinding mechanism screwed with the screw will move the grinding brush roller 1 to the right to another gap position. Similarly, the grinding brush roller 1 can continue to grind different areas of the outside of the furnace tube and the outside of the fin at the second gap. Similarly, the grinding brush roller 1 can stop and grind at different gap positions between the two furnace tubes from left to right, making it convenient for the grinding mechanism to move along the axial direction of the furnace tube and perform all-round grinding on the outside of the fins at different positions in the axial direction of the furnace tube and the outside of the furnace tube at the fin position;

[0028] To sum up, by inserting the grinding brush roller 1 into the gap between the spiral fins of the two furnace tubes, the grinding brush roller 1 and the rotating furnace tube remain in a relatively static state, which can grind the outside of the furnace tube and the outside of the fin curved surface around the gap. By utilizing the effect of directionally conveying the grinding brush roller 1 after the spiral fin rotates, the grinding brush roller 1 can move along the axial direction of the furnace tube while grinding different areas of the outside of the furnace tube, making it convenient for the grinding brush roller 1 to perform all-round grinding of the complex spiral curved surface of the convex fin and grind the two furnace tubes at the same time, which is beneficial to improving the grinding efficiency of the furnace tube.

[0029] 2. A syringe is fixed on the base, one end of the syringe is connected to an arc tube through a hose, and two water outlet holes at the bottom of the arc tube are respectively arranged above the corresponding furnace tube, and the same end of the syringe is connected to the external coolant through the hose. When the cylinder drives the carrier box to move back and forth so that the grinding brush roller and the furnace tube rotating inward and outward remain relatively stationary, the carrier box drives the piston rod inside the syringe to move back and forth inside the syringe with the piston. The piston rod drives the piston to move toward the hose so that one hose can add coolant to the outside of the furnace tube area in the grinding state through the arc tube, and the piston rod drives the piston to move away from the hose so that the other hose can draw coolant from the outside to the syringe for standby use, thereby realizing the combination of coolant addition and furnace tube grinding, achieving the effect of adding coolant while grinding, which is beneficial to improving the overall efficiency of furnace tube grinding;

[0030] The arc tube is fixed on the grinding mechanism and can move synchronously with the movement of the grinding mechanism, so that the arc tube can accurately add coolant to the grinding position, which helps to save coolant compared to the traditional direct large-area spraying of coolant.

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1. Please refer to Figure 1 - Figure 11 , in the embodiment of the present invention, a grinding device for the outer convex ribs of a superalloy furnace tube includes a base 100. A bearing box 200 is slidably connected to the top surface of the base 100. One end of the bearing box 200 is fixedly connected to a first support seat 210, and the other end of the bearing box 200 is slidably connected to a second support seat 220. A fixture 230 is rotatably provided on the top of the first support seat 210. The furnace tube is rotatably installed between the first support seat 210 and the second support seat 220 through the fixture 230. A first motor 400 is fixedly installed on the top of one first support seat 210. The first motor 400 is used to drive the fixture 230 to rotate the furnace tube. A U-shaped rod 110 is fixedly connected to the top surface of the base 100. A grinding mechanism 500 is arranged outside the U-shaped rod 110. The grinding mechanism 500 includes a support plate 510 slidably connected to the U-shaped rod 110. A telescopic member is rotatably connected below the support plate 510. A first grinding brush roller 530 is fixedly installed at the bottom of the telescopic member. A driving mechanism 7 {00} is arranged outside the grinding mechanism 500. The driving mechanism 7 {00} includes a screw rod 720 threadedly connected to the support plate 510.

[0045] Specifically, by inserting the first grinding brush roller 530 into the rib gap position between two furnace tubes and keeping the first grinding brush roller 530 stationary relative to the rotating furnace tube, the first grinding brush roller 530 can grind the outer curved surface of the furnace tube and the outer curved surface of the ribs at the gap position. During grinding, the coolant adding member 600 can drip coolant into the grinding area, achieving the combination of coolant addition and furnace tube grinding while saving coolant, and improving the overall efficiency of furnace tube grinding and cooling. By moving the position of the first grinding brush roller 530 relative to the rotating furnace tube, it is convenient for the first grinding brush roller 530 to move along the axial direction of the furnace tube to perform azimuth grinding on different regions on the outer side of the axial direction of the furnace tube.

[0046] As Figure 5 and Figure 6 shown, in this embodiment, a support shaft 221 is rotatably connected to the top of the second support seat 220. A first guide rail 240 fixedly connected to the bearing box 200 at one end is slidably connected to the second support seat 220. A bolt 222 is detachably fixed between the two second support seats 220 and the first guide rail 240.

[0047] In this embodiment, when installing the furnace tube, first move the support seat 220 in the direction away from the support seat 1 210 so that the gap between the support seat 1 210 and the support seat 2 220 is sufficient to place the furnace tube. After one end of the furnace tube is sleeved on the clamp 230, move the support seat 220 in the direction close to the furnace tube so that the support shaft 221 is inserted into one end of the furnace tube, and then the furnace tube is rotated and installed between the clamp 230 and the support shaft 221. Finally, insert and fix the bolt 222 between the support seat 220 and the guide rail 1 240 to fix the position of the support seat 220 so that the installed furnace tube will not separate from the support seat 1 210 and the support seat 2 20.

[0048] like Figure 3 and Figure 4 As shown, in this embodiment, a cylinder 120 is fixed to the top surface of the base 100, and the output end of the cylinder 120 is fixedly connected to the carrier box 200. The contraction or extension of the output end of the cylinder 120 can make the carrier box 200 move back and forth linearly along the guide rail 2 on the top surface of the base 100, so that the grinding brush roller 530 inserted into the gap between the two furnace tubes can remain relatively stationary with the furnace tube during the rotation of the furnace tube, and the spiral ribs on the furnace tube cannot drive the grinding brush roller 530 to move.

[0049] like Figure 7 As shown, in this embodiment, the telescopic part includes a sleeve 540 rotatably connected to the support plate 510, and a slide rod 550 is slidably engaged at the bottom of the sleeve 540. The slide rod 550 is fixedly connected to the grinding brush roller 1 530, and a motor 2 520 capable of driving the sleeve 540 to rotate is fixed on the top surface of the support plate 510.

[0050] In this embodiment, the output end of motor 2 520 drives sleeve 540 to rotate, and sleeve 540 drives slide bar 550 to rotate to rotate grinding brush roller 1 530, so that grinding brush roller 1 530 can grind the furnace tube, wherein the outer grinding brush body of grinding brush roller 1 530 is flexible and can be in close contact with the complex curved surface on the outside of the furnace tube. The grinding brush roller is a prior art component and its specific structure will not be described in detail.

[0051] In this embodiment, a slide groove is provided on the outside of the slide rod 550, and a slider is fixed on the inside of the sleeve 540 to slide and engage with the slide groove. The slider slides inside the slide groove, which helps to adjust the position height of the slide rod 550 along the sleeve 540 and also rotates as the sleeve 540 rotates. Figure 2 , it is necessary to first slide the slide rod 550 into the sleeve 540 , and after the two furnace tubes are installed, slide the slide rod 550 out from the sleeve 540 and insert it into the gap between the two furnace tubes.

[0052] like Figure 1 and Figure 4As shown, in this embodiment, the driving mechanism 700 also includes two columns 710 fixedly connected to the base 100, and the two ends of the screw rod 720 are respectively rotatably connected to the corresponding columns 710. A motor 730 that can drive the screw rod 720 to rotate is fixed to the top of one column 710.

[0053] In this embodiment, when it is necessary to drive the grinding mechanism 500 to move the grinding brush roller 530 to the right to change the gap position for grinding, the output end of the motor three 730 rotates with the screw rod 720, and the support plate 510 screwed together with the screw rod 720 moves the telescopic part to the right, so that the grinding brush roller 530 at the bottom of the telescopic part can move to the right synchronously during the outward rotation of the furnace tube, so that the grinding brush roller 530 can move to different gap positions on the furnace tube. Of course, the output end of the motor three 730 rotates in the opposite direction, and cooperates with the inward rotation of the two furnace tubes to enable the grinding brush roller 530 moved to the right to move to the left.

[0054] like Figure 6 and Figure 8 As shown, in this embodiment, the clamp 230 includes a support tube 231 rotatably connected to the support seat 210, and a gear 232 and a rotating block 233 are fixed to one end of the support tube 231. An adjusting rod 234 is provided inside the support tube 231, which can abut and fix the furnace tube from the inside of the furnace tube. The adjusting rod 234 includes a connecting column 2341, and both ends of the connecting column 2341 are provided with a stud 2342 that is screwed together with the support tube 231, and one end of the stud 2342 is fixed with a frustum block 2343, and one end of a stud 2342 is fixed with a rotating tube 2344 that is rotatably connected to the support tube 231. The two ends of the connecting column 2341 are respectively fixedly connected to the stud 2342 and the frustum block 2343 at corresponding positions, and a plurality of movable blocks 235 are evenly abutted and slidably provided on the outer side of the curved surface of the frustum block 2343. An arc plate 236 is fixed between two relatively movable blocks 235, and the movable block 235 is slidably engaged with the support tube 231.

[0055] In this embodiment, when it is necessary to use the clamp 230 to fix one end of the furnace tube, first, one end of the furnace tube is sleeved onto the outer side of the multiple curved plates 236, and then the existing technology tool vise is used to clamp and fix the rotating block 233, so that the support tube 231 cannot rotate on the support seat 210, and then the drill bit of the existing technology power tool is inserted into the hexagonal drill bit at one end of the rotating tube 2344, and the power tool rotates with the hexagonal drill bit to rotate the rotating tube 2344 with the two studs 2342. The studs 2342 rotate and move inward along the support tube 231, so that the outer curved surfaces of the multiple frustum blocks 2343 abut against the bottom surface of the movable block 235, so that the multiple movable blocks 235 move toward the inside of the furnace tube with the multiple curved plates 236, and finally the multiple curved plates 236 abut and are fixed to the inside of the furnace tube, thereby achieving fixed installation of one end of the furnace tube on the clamp 230.

[0056] In this embodiment, the reverse rotation of the rotating tube 2344 can cause the stud 2342 to move the frustum block 2343 away from the movable block 235 , and the movable block 235 no longer abuts against the fixed furnace tube through the arc plate 236 , making it easier to remove the furnace tube from the fixture 230 .

[0057] like Figure 3 and Figure 6 As shown, in this embodiment, two gears 1 232 are meshed for transmission, and the output end of the motor 1 400 is fixed with a gear 2 410 meshed with the gear 1 232 for transmission. The output end of the motor 1 400 drives the gear 2 410 to rotate, and the gear 2 410 can drive a gear 1 232 to rotate, and then the two gears 1 232 can drive the two furnace tubes to rotate synchronously in opposite directions through the clamp 230.

[0058] like Figure 2 As shown, in this embodiment, a fixed block is fixed to one end of the piston rod 630, and the fixed block is installed and fixed to the carrier box 200. A one-way valve is installed and fixed inside the two hoses at one end of the syringe 610, so that the hose connected to the arc tube 620 can only transport the coolant inside the syringe 610 to the position of the arc tube 620, and the other hose can only transport the external coolant to the inside of the syringe 610 for standby, so that as the piston rod 630 moves back and forth linearly, the syringe 610 can continuously pump coolant to the position of the arc tube 620.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the carrier box 200 is arranged under the two ground furnace tubes, which can hold the falling coolant, and the collected coolant can be discharged to a designated position along the connecting pipe outside the carrier box 200, which is conducive to the recovery of the coolant.

[0060] like Figure 1 and Figure 2 As shown, in this embodiment, a protective shell 211 is fixed to the outside of the support base 210, and the protective shell 211 is sleeved on the outside of multiple gears (including gear 1 232, gear 2 410 and gear 3), which helps to protect the gears. Motor 1 400 is supported and fixed to one end of the carrier box 200 by an L-shaped support block.

[0061] like Figure 7 As shown, in this embodiment, one end of the arc tube 620 is sealed, and two water outlet holes 621 are opened at the bottom of the arc tube 620 so that the coolant can fall from the water outlet holes 621 to the outside of the furnace tube.

[0062] Embodiment 2, based on embodiment 1, is to grind and polish the outer sides of both ends of the furnace tube and the edges of the spiral fins.

[0063] As Figure 5 and Figure 6 shown, in this embodiment, a second grinding brush roller 300 is meshed and driven on the outside of the first gear 232. A shaft rod 310 is inserted and fixed in the middle of the second grinding brush roller 300. Both ends of the shaft rod 310 are rotatably connected to the first support base 210 and the second support base 220 respectively. A third gear meshed and driven with the first gear 232 at the corresponding position is fixed at one end of the shaft rod 310.

[0064] In this embodiment, referring to Figure 7 , the slide rod 550 can be retracted into the sleeve 540, and then the pin shaft 541 is inserted between the slide rod 550 and the sleeve 540, so that the first grinding brush roller 530 on the telescopic member does not contact the furnace tube. Then, the first motor 400 drives the second gear 410 to rotate at high speed. The second gear 410 drives the third gear to rotate at high speed through the first gear 232, so that the two second grinding brush rollers 300 grind the rib edges of the furnace tube on the outside of the furnace tube. At this time, the driving mechanism 700 can be used to move the grinding mechanism 500 back and forth above the furnace tube with the arc-shaped tube 620, and at the same time, the bearing box 200 can be moved left and right to add the coolant in the injection cylinder 610 to the furnace tube. Of course, the hose connected to the arc-shaped tube 620 can also be directly connected to the pipeline for pumping coolant outside to add coolant during grinding.

[0065] In this embodiment, the diameters of both ends of the second grinding brush roller 300 are designed to be larger than those at the middle position, which is convenient for both ends of the second grinding brush roller 300 to grind the regular cylindrical surfaces at both ends of the furnace tube. And the rotation direction of the furnace tube is opposite to the rotation direction of the second grinding brush roller 300 during grinding, further improving the grinding effect.

[0066] In this embodiment, as Figure 2 shown, a U-shaped stop rod is fixed between the two columns 710, and the U-shaped stop rod can prevent the hose from contacting the rotating second grinding brush roller 300.

[0067] As Figure 9 and Figure 11 shown, in the present invention, the grinding mechanism 500 of the present invention can also grind the Figure 11 spiral small fin furnace tube. The first grinding brush roller 530 is also arranged to rotate between adjacent fins of this type of furnace tube. The fixture 230 drives the furnace tube to rotate. During grinding, the driving mechanism 700 can directly drive the first grinding brush roller 530 on the grinding mechanism 500 to move along the axis direction of the furnace tube for grinding. Among them, the spiral small fins will not interfere with the linear movement of the first grinding brush roller 530 because the brush body of the first grinding brush roller 530 itself can undergo extrusion deformation to pass through the spiral small fins. At this time, the outer side of the first grinding brush roller 530 is a regular cylindrical surface as a whole.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0069] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
