[0015] Compared with the prior art, the present invention provides a roll turning device. When turning the roll, firstly, the distance between the movable support and the fixed support is made greater than the length of the roll, then the roll is lowered and moved horizontally, so that one end of the roll passes through the turning ring (the place where the roll is suspended is located at both ends of the roll body, so that when both ends of the roll pass through the turning ring, the suspension cable of the roll can also not interact with the turning ring) and then moves to the positioning chuck on the fixed support (preferably a three-claw or four-claw chuck commonly seen on the market, and has sufficient strength), then the first driving mechanism moves the movable support to move, so that the other end of the roll is at the positioning chuck of the movable support, and finally the two ends of the roll are fixed and clamped by the two positioning chucks, and the positioning chuck does not rotate, but only plays the role of supporting the roll. Then the third driving mechanism drives the turning ring to rotate, and at the same time the second driving mechanism drives the annular track to move along the length direction of the supporting bottom frame, so that the outer wall of the roll can be turned by the turning tool body.

[0016] The current traditional lathes for turning rolls are based on the same principle as conventional lathes, that is, after the two ends of the roll are clamped and fixed by chucks, the two chucks drive the roll to rotate, and then the turning tool moves horizontally to turn the surface of the roll body. However, in actual processing, it is found that due to the large mass of some rolls (tens of tons to dozens of tons), the speed of the rolls is very slow; at the same time, because the rolls are made of special materials with strong toughness and strength, they can only turn to a very small depth and travel a very small distance each time during turning, so the rolls need to rotate for a long time to complete the turning process, and the power requirement for driving the rolls is also high, which leads to a large comprehensive energy consumption and low turning efficiency.

[0017] When the turning equipment of the present application is used to process the roller, the two ends of the roller are only supported by two positioning chucks, and the roller does not rotate, so the kinetic energy consumption of driving the roller to rotate is greatly reduced; secondly, since the mass of the turning ring can be very small compared to the roller, the turning ring can not only greatly reduce energy consumption when turning, but also enable the turning tool body to have a relatively fast turning speed (although the turning speed will not be too fast due to the material of the roller, the limitation caused by the excessive weight of the roller itself is greatly reduced), thereby also improving the turning efficiency.

[0030] The present invention provides a roller turning equipment. When turning the roller 5, first, the distance between the movable support 3 and the fixed support 2 is made greater than the length of the roller 5. Then, the roller 5 is lowered and moved horizontally, so that one end of the roller 5 passes through the turning ring 7 (the places where the roller 5 is suspended are located at both ends of the roller body. In this way, when both ends of the roller 5 pass through the turning ring 7, the suspension cables and the like for suspending the roller 5 may not interact with the turning ring 7) and then moves to the positioning chuck 4 (preferably a three-jaw or four-jaw chuck commonly available on the market, and having sufficient strength) on the fixed support 2. Then, the first driving mechanism moves the movable support 3 to move, so that the other end of the roller 5 is located at the positioning chuck 4 of the movable support 3. Finally, the two ends of the roller 5 are fixed and clamped by the two positioning chucks 4, and the positioning chucks 4 do not rotate, but only play the role of supporting the roller 5. Then the third driving mechanism drives the turning ring 7 to rotate, and at the same time the second driving mechanism drives the annular track 6 to move along the length direction of the supporting bottom frame 1, so that the outer wall of the roller 5 can be turned by the turning tool body 8-1.

[0031] The current traditional lathe for turning the roller 5 is based on the same principle as the conventional lathe, that is, after the two ends of the roller 5 are clamped and fixed by the chucks, the two chucks drive the roller 5 to rotate, and then the turning tool moves horizontally to turn the surface of the roller 5. However, in actual processing, it is found that since the mass of some rollers 5 is very large (more than ten tons to dozens of tons), the rotation speed of the roller 5 is very slow; at the same time, since the rollers 5 are made of special materials with strong toughness and strength, they can only turn a very small depth and travel a very small distance each time during turning, so the roller 5 needs to rotate for a long time to complete the turning process, and the power requirement for driving the roller 5 is also high, which leads to a large comprehensive energy consumption and a very low turning efficiency.

[0032] When the turning equipment of the present application is used to process the rolling mill 5, the two ends of the rolling mill 5 are only supported by two positioning chucks 4, and they do not rotate. Therefore, the kinetic energy consumption of driving the rolling mill 5 to rotate is greatly reduced. Secondly, since the mass of the turning ring 7 can be very small relative to the rolling mill 5, the turning ring 7 can not only reduce energy consumption to a great extent during turning, but also enable the turning tool body 8-1 to have a relatively fast turning speed (although the material of the rolling mill 5 will not result in the turning speed being too fast, the limitation caused by the excessive weight of the rolling mill 5 itself is greatly reduced), thereby also improving the turning efficiency.

[0033] During actual processing, after one end of the roller 5 moves to the positioning chuck 4 of the fixed support 2, the second motor 27 drives the first screw rod 26 to rotate, and at the same time drives the movable support 3 to move toward the fixed support 2 through the linkage part 28 until the movable support 3 reaches a suitable position. The first movable seat 23 has a large length, so that it can be stably buckled on the support rail 22 and has sufficient supporting strength.

[0034] After the roller 5 is fixed, the first motor 13 drives the active gear 14 to rotate, and the active gear 14 drives the passive gear body 12 to rotate, and at the same time drives the turning ring 7 to rotate; wherein multiple active gears 14 drive the turning ring 7 to rotate at the same time, and the outer side of the turning ring 7 is supported by the support wheel 10, and the two sides are supported by the support balls 11, so that the turning ring 7 can not only rotate stably, but also its rotation stability is fully guaranteed, and the rotation speed is also fully guaranteed. Among them, the turning ring 7, the support wheel 10 and the support balls 11 in this application all adopt high-precision dimensions and matching, which ensures the position stability and activity stability of the turning tool. At the same time, the counterweight block 16 can balance the mass of the turning tool seat 8, the turning tool body 8-1, the first worm 52, the first seat body 84 and other structures, ensuring the turning stability.

[0035] During the rotation of the turning ring 7, the third motor 29 drives the displacement gear to rotate, and the displacement gear interacts with the displacement rack 30, so that the annular track 6 moves along the length direction of the support rail 22, and the turning tool body 8-1 can act on the roller 5. The second movable seat 24 has a certain length, which can improve the angle and activity stability of the annular track 6; at the same time, both sides of the annular track 6 are driven to move by the displacement gear, which further improves the activity stability of the annular track 6.

[0036] During the turning process, iron filings and the like will be generated, and after falling, they will act on the guide member 18. Since the middle part of the guide member 18 is convex, it can well prevent the iron filings from staying on the guide member 18; at the same time, the guide parts 19 on both sides of the guide member 18 can fully block the gap between the turning ring 7 and the annular track 6, and prevent the iron filings from entering between the turning ring 7 and the annular track 6, ensuring that the turning can be carried out stably. At the same time, the cooling liquid is injected into the cooling main pipe 20, and after being sprayed out through the cooling branch pipe 21, it acts between the turning tool body 8-1 and the rolling roller 5, playing a role of cooling and lubrication; and the guide member 18 and the guide part 19 can also well prevent the coolant from entering between the turning ring 7 and the annular track 6; since the guide member 18 rotates with the turning ring 7, the iron filings and the coolant can be thrown out under the action of centrifugal force, further ensuring the cleanliness between the turning ring 7 and the annular track 6.

[0037] In the conventional method of turning the roller 5, due to the particularity of the roller 5 material, the travel distance each time is small and the turning depth is also small. In the present application, the roller 5 is turned by a plurality of turning tool bodies 8-1 at the same time (preferably three in the present embodiment, and other plural turning tools can also be used according to the actual situation), and at the same time, the target radius of different turning tool bodies 8-1 during turning is different; more specifically, the target radius of the turning tool body 8-1 that first acts on the roller 5 is the largest, and then the target radius of the turning tool body 8-1 that is downstream is smaller, so when turning the roller 5, it can be designed so that the turning depth of each turning tool body 8-1 is small, so that the overall turning efficiency of the roller 5 can be improved by turning by a plurality of turning tool bodies 8-1 at the same time.

[0038] During actual turning, when the required turning depth design is completed, the first worm 52 is first rotated by the first hand wheel 53, and then the first worm 52 drives the first worm wheel 51 to rotate, and the first worm wheel 51 drives the fourth screw 56 to rotate. At this time, the fourth screw 56 can drive the action part 49 to move along the length direction of the installation groove 47, so that the sliding seat 8b moves toward the axial direction of the roller 5; and at this time, the first matching part 48 is engaged in the first adjustment groove 46, which ensures the displacement stability of the sliding seat 8b.

[0039] When the sliding seat 8b moves, it also drives the first indicator plate 65 to move, until it moves to the designated design position, and then stops rotating the first hand wheel 53. The first indicator bar 64, the first indicator plate 65, and the second indicator bar 66 act as a vernier caliper, which can move the sliding seat 8b to a more accurate position.

[0040] Then the worker manually rotates the second hand wheel 63, and drives the second worm 62 to rotate through the second hand wheel 63. The second worm 62 also drives the three second worm wheels 57 and the linkage seat 70 to move while rotating. When the second worm wheel 57 rotates, it drives the three fourth screw rods 56 to rotate respectively, and then the three fourth screw rods 56 drive the corresponding adjustment part 55 in the direction of the roller 5. The end of the adjustment part 55 is in contact with the end of the tool body seat 58, so that the adjustment part 55 drives the tool body seat 58 and the turning tool body 8-1 in the direction of the roller 5. Since the pitch of the three fourth screw rods 56 changes (increases or decreases) in sequence, and the rotation speed of the three second worm wheels 57 is equal, when the second worm wheel 57 rotates, the speed and distance of the three adjustment parts 55, the tool body seat 58 and the turning tool body 8-1 moving in the direction of the roller 5 are increased or decreased in an arithmetic difference. In this way, not only three (or other numbers, the same below) turning tool bodies 8-1 can be adjusted at one time, but also the target radius of the three turning tool bodies 8-1 can be arranged in an equidistant manner. In actual turning, the load of each turning tool body 8-1 is similar. According to the barrel principle, the design of this method can make each turning tool body 8-1 turn at maximum power, thereby ensuring the overall turning efficiency. At the same time, since different rollers 5 require different turning depths, and different rollers 5 have different turning depths, it is necessary to adjust the target radius of the three turning tool bodies 8-1. For example, if the turning depth of a certain roller 5 is 3i, then the depths of the processing ends of the three turning tool bodies 8-1 relative to the outer surface of the roller 5 before processing are i, 2i and 3i respectively; but if the turning depth of a certain roller 5 is 3t, then the depths of the processing ends of the three turning tool bodies 8-1 relative to the outer surface of the roller 5 before processing are t, 2t and 3t respectively; but whether it is 3i or 3t, all the turning tool bodies 8-1 can be adjusted to the required position at one time. Of course, after the adjustment is completed, the minimum target radius value will still be detected by corresponding instruments and equipment. If it does not meet the requirements, fine-tuning will be required.

[0041] While the second worm 62 is rotating, it drives the linkage seat 70 and the second indicator plate 71 to move, until the second indicator plate 71 moves to the designated design position, and then stops rotating the second hand wheel 63. The third indicator bar 72, the second indicator plate 71, and the fourth indicator bar 73 act as a vernier caliper, which can move the linkage seat 70 to a more precise position; the relationship between the displacement of the linkage seat 70 and the displacement of the three tool bodies 8-1 is linear, so when the position of the tool body 8-1 is actually adjusted, the required position of the tool body 8-1 can be obtained after calculation, and the unique position of the linkage seat 70 is also obtained; at the same time, because the linkage seat 70 can achieve the accuracy of a vernier caliper through the second indicator plate 71, etc., the tool body 8-1 can be moved to the designated precise position only by manual adjustment, and the use effect is articulated.

[0042] The spacing a between adjacent first indicator strips 64 is relatively large, while the spacing c between adjacent third indicator strips 72 is relatively small, so that the movement of the sliding seat 8b is a rough adjustment, while the adjustment of the second worm 62 is a fine adjustment, and finally the turning tool body 8-1 is moved to a suitable position. In actual use, the moving position of the first indicator plate 65 and the moving position of the second indicator plate 71 are both unique and fixed.

[0043] After the second worm 62 is adjusted, it is necessary to tighten the positioning screw 60, and make the positioning ball 61 at the bottom of the positioning screw 60 press against the inner wall of the stable groove 59; the inner wall of the stable groove 59 is inclined, so the stabilizing ball has a tendency to exert a movement of the blade seat 58 toward the adjustment part 55; in this way, the blade seat 58 is stably pressed against the end of the adjustment part 55. Since the width of the stable groove 59 is smaller than that of the blade seat 58, the blade seat 58 can maintain a stable fit in the second adjustment groove 54.

[0044] When the two ends of the roller 5 are supported and fixed by two positioning chucks 4 respectively, the turning ring 7 keeps rotating, and the annular track 6 keeps moving toward the roller body; at a certain node, the transition portion 78 at the end of the chip column 77 will first act on the end of the roller body. Since the transition portion 78 is dome-shaped (the inner end edge of the transition portion 78 is flush with the edge of the chip column 77), as the annular track 6 moves, the shape of the transition portion 78 will cause the chip column 77 to move a short distance toward the chip plate 74, and cause the elastic member 80 to deform to a small extent (before the transition portion 78 acts on the roller 5, the elastic member 80 is in the original length state), and the elastic column 75 passes through the chip plate 74 for a certain distance.

[0045] Later, during the formal turning process, since the roller 5 remains stationary, the chip column 77 is in contact with the surface of the roller 5 under the elastic force of the elastic member 80. At the same time, since the longitudinal section of the chip column 77 is elliptical, and the surface of the chip column 77 has a layer with greater resistance (such as a rubber layer, etc.) or the chip column 77 itself is made of a material with greater resistance, the chip column 77 cannot slide on the surface of the roller 5, but rotates under the action of the friction between it and the surface of the roller 5; at the same time, since the chip column 77 is elliptical, and the elastic column 75 and the elastic member 80 are both elastic, and the elastic column 75 can move through the chip plate 74, the chip column 77 remains in a jumping state during the turning process.

[0046] Since the material of the roller 5 is relatively special, when the tool body 8-1 is turning, it is easy to form long scraps, and the overlong scraps are easy to be entangled on the cooling branch pipe 21, and even cause damage to it. However, at this time, since the chip column 77 is located on the upstream side of the tool body 8-1 and can shake spontaneously, even if long or rolled scraps are formed on the tool body 8-1, the chip column 77 can vibrate, block and beat these scraps, and to a certain extent make these scraps more likely to break, so that it can better prevent the scraps from acting on the cooling branch pipe 21, and the scraps with smaller lengths are also convenient for subsequent processing.

[0047] Similarly, since different rolling mills 5 require different machining positions, the distance between the chip removal column 77 and the rolling mill 5 also needs to be adjusted. When adjusting, it is only necessary to rotate the rotating part 88 using a tool such as a wrench, and then the rotating part 88 can drive the adjusting screw 86 to rotate. At this time, the chip removal plate 74 can be driven to move in a direction away from or close to the turning ring 7, and it is suitable for the current rolling mill 5 requirements.

[0048] When connecting the rolling roller 5 to the two positioning chucks 4, if the hanging cable or the like cannot maintain the height or stability of the hanging rolling roller 5 well, the auxiliary plate 32 can be moved along the length direction of the auxiliary strip 31, so that the first support column 41 and the second support column 42 are located below the roller body, and then the cylinder is driven by the operating wheel 45 or the motor to rotate, which simultaneously drives the second screw rod 35 to rotate; the second screw rod 35 drives the two auxiliary blocks 36 to approach each other, and at the same time the first support arm 39 and the second support part rotate relative to each other, and finally the first support column 41 and the second support column 42 are in contact with the two sides of the oblique lower part of the roller body, so that the roller body can be supported auxiliaryly and the connection between the rolling roller 5 and the positioning chuck 4 is facilitated.

[0049] In another embodiment, the positioning chuck 4 includes a bottom chuck with an upward opening and a C-shaped top chuck with an upward opening, and the two are detachably connected by bolts; then, when supporting the roller 5, it is only necessary to lower the roller 5 and then move the roller 5 horizontally (the structure for hoisting the roller 5 is at both ends of the roller body, so that when the roller 5 is moved horizontally, the hoisting structure may not act on the turning ring 7), so that one end of the roller 5 passes through the turning ring 7; after one end of the roller 5 is located above the bottom chuck of the fixed support 2, the roller 5 is stopped; and then the movable roller 5 is translated The movable support 3 is moved so that the bottom chuck on the movable support 3 is located below the other end of the roller 5. At this time, it is only necessary to slowly lower the roller 5 so that the two ends of the roller 5 are respectively against the two bottom chucks; then the top chuck is moved to the top of the bottom chuck by an electric hoist, etc., and then cooperates with the bottom chuck, and finally the long screw is passed through the top chuck and threadedly connected with the bottom chuck, so that the two ends of the roller 5 are fully fixed by the top chuck and the bottom chuck; for large rollers 5, the top chuck may not be set according to actual conditions; or a rotary clamping cylinder (angle cylinder) may be used instead of the top chuck.
