[0002] Rollers are generally made of high-carbon chromium alloy steel, which has high hardness and good wear resistance. High-speed steel, carbide or ceramic materials are also used to improve the wear resistance and service life of the rolls. When grinding stainless steel pipes, the rolls are very important parts in the steel pipe production process. They are mainly used for surface treatment of stainless steel pipes to polish and remove the oxide layer, welds and other uneven places on the surface of the pipes, and improve the finish and dimensional accuracy of the stainless steel pipes.

[0003] A Chinese patent with authorization announcement number CN110026836B in the prior art discloses a device for polishing the outer wall of a stainless steel pipe.

Each of the mounting rails 600 is slidably connected to a roller; multiple pairs of the mounting rails 600 are evenly distributed circumferentially along the axis of the positioning sleeve 310 and the positioning column 210; multiple rolling rollers are evenly distributed outside the stainless steel pipe 500 along the outer periphery of the stainless steel pipe 500; the length direction of the mounting rail 600 fixed on the positioning sleeve 310 is at an acute angle to the length direction of the positioning sleeve 310, and preferably, the angle between the length direction of the mounting rail 600 and the length direction of the positioning sleeve 310 is between 30 degrees and 75 degrees; the mounting rail 600 is built with a slider 621, and the slider 621 is slidably arranged along the length direction of the mounting rail 600; the rolling roller includes a roller body 700 and two roller shafts 900, and the two roller shafts 900 are coaxially slidably inserted at both ends of the roller body 700, and the length of the roller body 700 is adapted to the length of the stainless steel pipe 500; the roller shaft 900 is fixedly connected to the slider 621 at one end away from the roller body 700.

[0035] The mounting rail 600 has a sliding cavity 620 formed inside along the length direction, the top of the sliding cavity 620 is open, an adjusting screw 630 is coaxially connected to the sliding cavity 620, the outer coaxial thread of the adjusting screw 630 is connected to a slider 621, the slider 621 and the sliding cavity 620 are slidably matched, the top of the adjusting screw 630 passes through the top opening of the sliding cavity 620, and an adjusting hand wheel 610 is fixed to the top of the adjusting screw 630, and the adjusting hand wheel 610 is used to control the adjustment. The screw rod 630 rotates to control the slider 621 to slide up and down in the sliding cavity 620. A sliding groove 640 is provided on the opposite surfaces of each pair of mounting rails 600.

A connecting shaft 622 is fixed on the slider 621. The side wall of the connecting shaft 622 is slidably connected to the sliding groove 640. The slider 621 is fixedly connected to one end of the roller shaft 900 through the connecting shaft 622.

[0036] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0037] In this embodiment, a positioning column 210 and a positioning sleeve 310 are set, and a mounting rail 600 is symmetrically set therebetween. The mounting rail 600 is set to an inclined state so that the roller slides on the mounting rail 600. The farther the roller is from the stainless steel pipe 500, the longer the extended length of the roller shaft 900 is, and the larger the space between the roller shaft 900 and the stainless steel pipe 500 is. This solves the technical problem of the prior art that the replacement of the roller is affected by the clamping mechanism and the operating space is narrow, and achieves the technical effect that after the roller body 700 is away from the stainless steel pipe 500, the roller shaft 900 extends outward, thereby facilitating the replacement of the roller body 700 and the stainless steel pipe 500.

[0038] Embodiment 2: Considering that in the above embodiment 1, when there are rough particles on the surface of the stainless steel tube 500, it is easy to cause the roller to vibrate during the polishing process, and when the diameter of the stainless steel tube 500 is small, the smaller the spacing between the multiple rollers, the more severe the vibration effect between them, which may easily cause the mounting rail 600 to be damaged or the accuracy to be reduced over time; secondly, when the diameter of the stainless steel tube 500 is large, the tube wall thickness of the stainless steel tube 500 is small relative to the diameter of the internal space. Due to the high temperature generated by the friction between the stainless steel tube 500 and the roller body 700, it is more likely to cause the surface of the stainless steel tube 500 to deform when the roller body 700 exerts a large pressure on the stainless steel tube 500. Therefore, when the thickness of the stainless steel tube 500 is large, it is necessary to allow the roller body 700 to have an appropriate vibration activity margin to prevent the stainless steel tube 500 from being deformed due to excessive pressure. Therefore, it is necessary to improve the device, such as Figure 4 As shown, the specific structure is as follows:

[0039] The roller body 700 is provided with a movement cavity 710 inside, and the movement cavity 710 is coaxially arranged inside the roller body 700. Both ends of the movement cavity 710 in the length direction are provided with movable grooves 720, and the movable grooves 720 penetrate the side walls at both ends of the length direction of the roller body 700. The two roller shafts 900 respectively pass through a movable groove 720 coaxially, and the diameter of the roller shaft 900 is one third of the diameter of the movable groove 720. The ends of the two roller shafts 900 close to each other are respectively hinged with a movement plug 920 through a hinge shaft 910, and a shock absorbing capsule 930 is fixed between the opposite surfaces of the two movement plugs 920. The shock absorbing capsule 930 is provided with a closed cavity inside, and the cavity is filled with gas. The shock absorbing capsule 930 is a long strip capsule made of elastic rubber. When the roller body 700 moves to When sliding away from the stainless steel pipe 500, the roller shaft 900 drives the moving plug 920 away from each other, so that the shock absorbing bag 930 is stretched, and the contact between the shock absorbing bag 930 and the inner wall of the moving cavity 710 is reduced, thereby weakening the shock absorbing ability, so that the roller body 700 is easy to disassemble, and the roller body 700 can reserve more activity margin for the stainless steel pipe 500 with a larger diameter, thereby reducing the pressure applied to the stainless steel pipe 500; when the diameter of the stainless steel pipe 500 is small, when the roller body 700 slides toward the axial direction of the stainless steel pipe 500, the roller shafts 900 at both ends approach each other and drive the moving plug 920 to approach each other, and make the moving plug 920 squeeze the shock absorbing bag 930, so that the shock absorbing bag 930 expands and squeezes the inner wall of the moving cavity 710, thereby improving the shock absorbing effect on the roller body 700.

[0040] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0041] In this embodiment, a motion cavity 710 and a shock-absorbing bag 930 are provided so that the shock-absorbing bag 930 is matched with the extension amount of the roller shaft 900. The closer the multiple roller bodies 700 are to each other, the stronger the shock-absorbing effect of the shock-absorbing bag 930 on the roller bodies 700 is. When they are far away from each other, the shock-absorbing bag 930 and the movable groove 720 jointly provide a certain amount of movable margin for the roller body 700, thereby reducing the risk of possible deformation of the stainless steel pipe 500.

[0042] Embodiment 3: Considering that in the above-mentioned embodiment 2, since the shock-absorbing capsule 930 expands between the two moving plugs 920, when the expansion amount of the shock-absorbing capsule 930 is large, the distance between the moving plugs 920 is difficult to continue to close. At the same time, since the vibration of the roller body 700 is more significant at its two ends and the roller shaft 900, the greater the radial expansion amount of the shock-absorbing capsule 930, the more concentrated it is in the middle of the roller body 700, and the shock-absorbing effect is easy to gradually weaken from the middle of the roller body 700 to the two ends. Therefore, it is necessary to improve the device, such as Figures 5 to 7 As shown, the specific structure is as follows:

[0043] The roller shaft 900 is partially fixedly sleeved with a collar block 940 in the roller body 700 . The moving plug 920 is provided with a sliding hole 921 . Both ends of the shock absorbing bag 930 respectively pass through the sliding hole 921 and are fixedly connected to the side wall of the collar block 940 .

[0044] When the moving plug 920 squeezes the shock absorbing bag 930, the middle part of the shock absorbing bag 930 expands after being squeezed, and the parts of the two ends of the shock absorbing bag 930 close to the roller shaft 900 will expand synchronously. When the distance between the two moving plugs 920 is closer, the more gas in the middle part of the shock absorbing bag 930 flows to the two ends, so that the two ends of the shock absorbing bag 930 fix and dampen the hinge shaft 910 and the roller shaft 900.

[0045] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0046] In this embodiment, the sliding hole 921 is provided to allow the two ends of the shock-absorbing bag 930 to pass through the moving plug 920, so that the two ends of the shock-absorbing bag 930 continue to expand as the moving plug 920 approaches, so that the resistance of the two moving plugs 920 approaching each other is relatively reduced, and at the same time, the side of the moving plugs 920 that is away from each other retains a certain damping under the control of the end of the shock-absorbing bag 930, so that during use, the closer the roller is to the stainless steel pipe 500, the stronger the resistance of the control hand wheel 610 is, so that the user's control accuracy is higher, and the user can be reminded to prevent the user from turning the adjustment hand wheel 610 too many times, thereby preventing the roller body 700 from applying a strong pressure on the stainless steel pipe 500, thereby avoiding damage to the stainless steel pipe 500; when the moving plug 920 approaches, the gas in the middle of the shock-absorbing bag 930 flows to the two ends as the moving plug 920 approaches each other, so that the two ends of the shock-absorbing bag 930 are fixed and damped on the roller shaft 900, thereby further improving the damping effect on the roller body 700.

[0047] Embodiment 4: Considering that the shock absorbing capsule 930 in the above-mentioned embodiment 3 can expand to contact the side wall of the movement cavity 710 only when the two moving plugs 920 are constantly approaching to a certain distance and the middle part of the shock absorbing capsule 930 is squeezed more, the two ends of the shock absorbing capsule 930 can hardly produce damping and shock absorption when it has not expanded to contact the side wall of the movement cavity 710. Secondly, after the two ends of the shock absorbing capsule 930 contact the side wall of the movement cavity 710, the damping at the two ends of the shock absorbing capsule 930 will increase rapidly, and the increase in damping lacks transition, which makes the user's operation not smooth enough. Therefore, it is necessary to improve the device, such as Figures 8 to 10 As shown, the specific structure is as follows:

[0048] The collar block 940 is cylindrical as a whole, and a plurality of annular capsules 950 are coaxially fixedly sleeved on the collar block 940. The annular capsules 950 are annular capsules made of elastic rubber, and a cavity is provided inside the annular capsules 950. The elastic coefficient of the annular capsules 950 is smaller than the expansion coefficient of the shock absorbing capsules 930. The plurality of annular capsules 950 are arranged along the length direction of the collar block 940, and the end of the shock absorbing capsules 930 is fixed to the end of the collar block 940. A ventilation groove 941 is provided inside the collar block 940 along the length direction. A control block 944 is slidably connected, and an air inlet hole 943 is provided at the connection between the shock absorbing bag 930 and the ring block 940, and both ends of the air inlet hole 943 are respectively connected to the internal space of the shock absorbing bag 930 and the ventilation groove 941; a ventilation hole 942 is provided between each of the ring bags 950 and the ventilation groove 941, and the aperture of the ventilation hole 942 is smaller than the length of the control block 944, and a rubber pad is fixed to the side wall of the control block 944 that contacts the ventilation groove 941, and the rubber pad is used to provide resistance to the sliding of the control block 944.

[0049] Initially, the control block 944 is located between the vent hole 942 and the air inlet hole 943. When the gas in the middle of the shock absorbing bag 930 flows toward both ends, the gas pushes the control block 944 to move away from one end of the shock absorbing bag 930. After each vent hole 942 is passed through by the control block 944, the gas flows into the annular bag 950 corresponding to the vent hole 942. When the annular bag 950 is fully inflated, the control block 944 continues to move away from the shock absorbing bag 930 under the push of the gas, thereby causing multiple annular bags 950 to expand in sequence.

[0050] Furthermore, in order to improve the stability of the shock absorbing effect of the annular capsule 950, the closer the roller body 700 is to the stainless steel tube 500, the better the stability of the annular capsule 950 is. At the same time, the speed at which the resistance of the annular capsule 950 increases needs to be slowed down to ensure the control accuracy of the user. Therefore, the following improvements are made to the device, such as Fig.10 :

[0051] The width of the plurality of ring capsules 950 increases stepwise from the side close to the shock absorbing capsule 930 to the side away from the shock absorbing capsule 930. The ring capsule 950 away from the shock absorbing capsule 930 is connected to one more corresponding vent hole 942 than the adjacent ring capsule 950 close to the shock absorbing capsule 930. A smart valve 945 is fixed inside each of the vent holes 942. A control system is provided on the base 100. The smart valve 945 is connected to the control system signal. The user can set the on / off state of the smart valve 945 through the control system. The control system is a programmable logic controller. By increasing the width of the ring capsule 950 stepwise and the corresponding number of vent holes 942, the smaller the diameter of the stainless steel pipe 500 is, the higher the stability of the roller body 700 is, and the stronger the shock absorption effect is.

[0052] A control rod 946 is fixed to the side of the control block 944 away from the shock absorbing bag 930, and the end of the control rod 946 away from the control block 944 in the length direction passes through the side wall of the ring block 940, so that the user can reset the control block 944 by operating the control rod 946. At the same time, when the user operates the roller body 700 to move away from the stainless steel pipe 500, the ring block 940 gradually extends out of the movable groove 720, so that under the squeezing of the movable groove 720 and the rebound of the shock absorbing bag 930, the ring bag 950 shrinks.

[0053] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0054] In this embodiment, a plurality of annular capsules 950 are arranged on the ring block 940, so that the annular capsules 950 are expanded sequentially, thereby avoiding the problem that when the two ends of the shock-absorbing capsule 930 are not expanded to contact the side walls of the motion cavity 710, it is difficult for the two ends of the shock-absorbing capsule 930 to produce a shock-absorbing effect. At the same time, the sequential expansion of the annular capsules 950 increases the resistance smoothness of the user's operation of the adjustment hand wheel 610, making the increase in damping smoother and more distinct, thereby improving the stability of the roller body 700, and the shock-absorbing effect of the roller body 700 gradually increases with the sequential expansion of the annular capsules 950.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
