Description

Technical Field

[0001] The invention belongs to the technical field of roller turning and relates to roller turning equipment. Background Art

[0002] Rollers are the primary working components and tools in a rolling mill that produce continuous plastic deformation of metal. They consist primarily of three parts: the roll barrel, the roll neck, and the shaft head. The roll barrel is the center portion of the roll that actually rolls the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in bearings, which transmit the rolling force to the mill frame via a bearing seat and a screw-down mechanism. The shaft head at the drive end is connected to the gear housing via a connecting shaft, transmitting the motor's torque to the rolls. Rolls can be arranged in a two-roll, three-roll, four-roll, or multi-roll configuration within the mill frame.

[0003] At present, after a period of use, the roller body surface usually needs to be turned (or scraped). During turning, the shaft heads at both ends need to be fixed by two chucks, and then the chucks drive the roller to rotate, and the turning tool seat moves at the same time, so that the turning tool can turn the roller body surface.

[0035] Compared to the prior art, the present invention provides a roll turning device. When turning a roll, the distance between the movable support and the fixed support is first made greater than the length of the roll. The roll is then lowered and moved horizontally, allowing one end of the roll to pass through a turning ring (the roll is suspended at each end of the roll body. This allows the suspension cables, etc., suspending the roll, to avoid interaction with the turning ring when the ends pass through the turning ring). The roll is then moved to a positioning chuck (preferably a commercially available three- or four-jaw chuck of sufficient strength) on the fixed support. A first drive mechanism then moves the movable support, positioning the other end of the roll against the positioning chuck on the movable support. Finally, the two positioning chucks securely clamp the ends of the roll, preventing them from rotating and merely supporting the roll. A third drive mechanism then rotates the turning ring, while a second drive mechanism simultaneously drives the circular track along the length of the support base frame, enabling the tool body to turn the outer wall of the roll.

[0036] The current traditional lathes used to turn rolls follow the same principle as conventional lathes: 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 very large mass of some rolls (tens of tons to dozens of tons), the roll rotation speed 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 short distance each time. Therefore, the rolls need to rotate for a long time to complete the turning process, and the power required to drive the rolls is also high. This leads to high overall energy consumption and low turning efficiency.

[0037] 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 it 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 made 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 material of the roller will not cause the turning speed to be too fast, the limitation caused by the excessive weight of the roller itself is greatly reduced), thereby also improving the turning efficiency.

A hexagonal rotating portion 88 is provided on the outer wall of the adjusting screw 86.

[0086] The present invention provides a roller turning equipment. When turning the roller 5, the distance between the movable support 3 and the fixed support 2 is first 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 place where the roller 5 is suspended is 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 cable suspending the roller 5 does not interact with the turning ring 7) and then moves to the positioning chuck 4 on the fixed support 2 (preferably a three-jaw or four-jaw chuck commonly available on the market, and having sufficient strength). 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 chuck 4 does not rotate, but only serves to support 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.

[0087] The traditional lathes used to turn the roller 5 currently operate on the same principle as conventional lathes: after the roller 5 is clamped and fixed at both ends by 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 was found that due to the very large mass of some rollers 5 (tens of tons to dozens of tons), the rotation speed of the roller 5 is very slow. At the same time, because the roller 5 is made of special materials with strong toughness and strength, it can only turn to a very small depth and travel a very short distance each time. Therefore, the roller 5 needs to rotate for a long time to complete the turning process, and the power required to drive the roller 5 is also high. This leads to high overall energy consumption and low turning efficiency.

[0088] When the turning equipment of the present application is used to process the roller 5, the two ends of the roller 5 are only supported by two positioning chucks 4, and it does not rotate, so the kinetic energy consumption of driving the roller 5 to rotate is greatly reduced; secondly, since the mass of the turning ring 7 can be made very small relative to the roller 5, the turning ring 7 can not only greatly reduce energy consumption when turning, but also enable the turning tool body 8-1 to have a relatively fast turning speed (although the material of the roller 5 causes the turning speed to not be too fast, the limitation caused by the excessive weight of the roller 5 itself is greatly reduced), thereby also improving the turning efficiency.

[0089] During actual machining, 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 26 to rotate, which in turn drives the movable support 3 toward the fixed support 2 through the linkage 28 until the movable support 3 reaches the desired position. The first movable seat 23 has a large length, which allows it to be stably engaged with the support rail 22 and provide sufficient support strength.

[0090] 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, thereby driving the turning ring 7 to rotate; wherein multiple active gears 14 simultaneously drive the turning ring 7 to rotate, 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 fit, 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, thereby ensuring turning stability.

[0091] As the turning ring 7 rotates, the third motor 29 drives the displacement gear, which interacts with the displacement rack 30, causing the annular track 6 to move along the length of the support rail 22 and enabling the turning tool body 8-1 to act on the roller 5. The second movable seat 24 has a certain length, which can improve the angle and movement stability of the annular track 6. At the same time, both sides of the annular track 6 are driven by the displacement gear, further improving the movement stability of the annular track 6.

[0092] During the turning process, iron chips and other debris are generated and fall onto the guide member 18. The convex center portion of the guide member 18 effectively prevents the chips from accumulating on the guide member 18. Simultaneously, the guide portions 19 on either side of the guide member 18 fully block the gap between the turning ring 7 and the annular track 6, preventing them from entering the gap and ensuring stable turning. Coolant is injected into the cooling manifold 20 and ejected through the cooling branch pipes 21 to the space between the tool body 8-1 and the roll 5, providing cooling and lubrication. The guide member 18 and guide portions 19 also effectively prevent coolant from entering the gap between the turning ring 7 and the annular track 6. Since the guide member 18 rotates with the turning ring 7, the centrifugal force ejects both the chips and the coolant, further ensuring a clean space between the turning ring 7 and the annular track 6.

[0093] In conventional turning of the roll 5, due to the special nature of the roll 5 material, the travel distance and cutting depth are relatively small each time. In the present application, however, the roll 5 is turned simultaneously by multiple tool bodies 8-1 (preferably three in this embodiment, but other multiple tool bodies may be used depending on the actual situation). Furthermore, the target radius of each tool body 8-1 during turning is different; more specifically, the target radius of the tool body 8-1 that first acts on the roll 5 is the largest, and the target radius of each tool body 8-1 further downstream decreases. This allows the design of a smaller turning depth for each tool body 8-1 during turning of the roll 5. This allows the simultaneous turning of multiple tool bodies 8-1 to improve the overall turning efficiency of the roll 5.

[0094] During actual turning, when the required turning depth design is completed, the first worm 52 is first rotated by the first handwheel 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, ensuring the displacement stability of the sliding seat 8b.

[0095] When the sliding seat 8b moves, it also drives the first indicator plate 65 to move until it moves to its 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 precise position.

[0096] The worker then manually turns the second handwheel 63, which in turn drives the second worm 62. This rotation also drives the three second worm wheels 57 and the linkage seat 70. The rotation of the second worm wheel 57 drives the three fourth screws 56, which then drive the corresponding adjustment portion 55 toward the roll 5. The ends of the adjustment portions 55 abut against the ends of the tool holder 58, thereby driving the tool holder 58 and the turning tool body 8-1 toward the roll 5. Because the pitches of the three fourth screws 56 change sequentially (increasing or decreasing), while the rotational speeds of the three second worm wheels 57 are equal, the speed and distance of the movement of the three adjustment portions 55, the tool holder 58, and the turning tool body 8-1 toward the roll 5 increase or decrease in an arithmetic progression as the second worm wheel 57 rotates. This method not only allows for simultaneous adjustment of three (or any other number, the same below) turning tool bodies 8-1, but also ensures that the target radii of the three turning tool bodies 8-1 are arranged in an equidistant pattern. During actual turning, the load on each turning tool body 8-1 is similar. Based on the wooden barrel principle, this design allows each turning tool body 8-1 to perform turning at maximum power, thereby ensuring overall turning efficiency. Furthermore, because different rollers 5 require different turning depths, and the turning depths of different rollers 5 also vary, the target radii of the three turning tool bodies 8-1 need to be adjusted. For example, if the turning depth of a particular roller 5 is 3i, the depths of the machining ends of the three turning tool bodies 8-1 relative to the outer surface of the roller 5 before machining are i, 2i, and 3i, respectively. However, if the turning depth of a particular roller 5 is 3t, the depths of the machining ends of the three turning tool bodies 8-1 relative to the outer surface of the roller 5 before machining are t, 2t, and 3t, respectively. Regardless of whether the turning depth is 3i or 3t, all turning tool bodies 8-1 can be adjusted to the desired position at once. 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.

[0097] As the second worm 62 rotates, it drives the linkage seat 70 and the second indicator plate 71 to move. When the second indicator plate 71 moves to its designated design position, the second hand wheel 63 stops rotating. The third indicator bar 72, the second indicator plate 71, and the fourth indicator bar 73 act as a vernier caliper, enabling the linkage seat 70 to move to a more precise position. The relationship between the displacement of the linkage seat 70 and the displacement of the three turning tool bodies 8-1 is linear. Therefore, when the position of the turning tool body 8-1 is actually adjusted, the desired position of the turning tool body 8-1 can be obtained through calculation, and at the same time, the unique position of the linkage seat 70 is 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 turning tool body 8-1 can be moved to the designated precise position through manual adjustment, resulting in an articulated effect.

[0098] 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. This allows the movement of the sliding seat 8b to be a rough adjustment, while the adjustment of the second worm 62 is a fine adjustment, ultimately moving the tool body 8-1 to the appropriate position. In actual use, the movement positions of the first indicator plate 65 and the second indicator plate 71 are both uniquely fixed.

[0099] After the second worm 62 is adjusted, the positioning screw 60 needs to be tightened so that the positioning ball 61 at the bottom of the positioning screw 60 abuts against the inner wall of the stabilizing groove 59. The inner wall of the stabilizing groove 59 is inclined, so the stabilizing ball tends to force the blade seat 58 toward the adjustment portion 55. This ensures that the blade seat 58 is stably abutted against the end of the adjustment portion 55. Since the width of the stabilizing groove 59 is smaller than that of the blade seat 58, the blade seat 58 can remain stably fitted within the second adjustment groove 54.

[0100] 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 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 its original length state), and the elastic column 75 passes through the chip plate 74 for a certain distance.

[0101] 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.

[0102] Due to the special material of the roller 5, long scraps are easily formed during the turning process of the tool body 8-1. Such long scraps can easily become entangled in the cooling branch pipe 21, even damaging it. However, since the chip removal column 77 is located on the upstream side of the tool body 8-1 and can vibrate spontaneously, even if long or curled scraps form on the tool body 8-1, the chip removal column 77 can vibrate, block, and beat the scraps, making them more likely to break to a certain extent. This effectively prevents the scraps from affecting the cooling branch pipe 21, and also makes the shorter scraps easier to handle.

[0103] Similarly, since different rollers 5 require different machining positions, the distance between the chip removal column 77 and the roller 5 also needs to be adjusted. When adjusting, it is only necessary to rotate the rotating part 88 using a wrench or other tool, 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 the direction away from or close to the turning ring 7, and it is suitable for the current roller 5 requirements.

[0104] 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 suspending rolling roller 5 well, the auxiliary plate 32 can be moved along the length direction of the auxiliary bar 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 makes the first support column 41 and the second support column 42 contact the two sides of the oblique lower part of the roller body, so that it can play the role of auxiliary support of the roller body and facilitate the connection of the rolling roller 5 with the positioning chuck 4.

[0105] In another embodiment, the positioning chuck 4 includes a bottom chuck with an upward opening in a C shape and a top chuck with an upward opening in a C shape, 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 does 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 from moving; and then the movable roller 5 is moved horizontally. 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 in contact with 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. Finally, the long screw is passed through the top chuck and threadedly connected to the bottom chuck. In this way, 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) can be used instead of the top chuck.

[0106] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
