Description

Technical Field

[0001] This utility model relates to the field of roller ring processing technology, and in particular to a roller ring hot processing rotary support device. Background Technology

[0002] Roll rings are the parts between or outside the grooves on the roll body of profile rolling mills. To achieve better quality, roll rings need to undergo heat treatment.

[0003] In existing support devices, the groove diameter of the placement plate is fixed. When placing small-diameter roller rings, the groove is too large, preventing the roller ring from fitting snugly against the placement plate, and the center of the ring hole inside the roller ring cannot be aligned with the center of the clamping mechanism. When placing large-diameter roller rings, the groove is too small, directly preventing the roller ring from being placed. Regardless of whether the roller ring is large or small, it cannot be properly clamped by the clamping mechanism, necessitating heat treatment of the roller ring. At the same time, the roller ring undergoes continuous sliding friction with the placement plate during rotation, causing localized damage to the contact surfaces between the roller ring and the placement plate, resulting in economic losses.

[0004] A search revealed a Chinese patent with publication number CN220099129U that discloses a roller ring heat treatment support device. This utility model achieves the effect that the roller ring can rotate without clamping mechanism simply by being placed on the shaft. It changes the original sliding friction to rolling friction, avoiding strong friction between the roller ring and the support surface during rotation, which could lead to local damage.

[0005] In actual use, the above-mentioned support device can rotate different types of roller rings. However, the stress points of different types of roller rings are different. If the roller ring is rotated without achieving good stress, the stability of the roller ring rotation will be greatly reduced, resulting in an unstable rotation of the roller ring. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a roller ring hot working rotary support device.

[0007] This utility model is achieved through the following technical solution:

[0008] A rotary support device for hot processing of roller rings includes a worktable with multiple insertion holes on its top. A servo motor is fixedly connected to the bottom of the worktable, and a rotating shaft is fixedly connected to the output end of the servo motor. A sealing gasket is fixedly connected to the inner side of the worktable. The rotating shaft passes through the sealing gasket and the inner side of the worktable and extends to the outer side of the worktable. A turntable is fixedly connected to the top of the rotating shaft, and a support mechanism is provided on the outer side of the turntable. The support mechanism includes multiple support columns, the bottom of which is fixedly connected to the top of the turntable. Two arc-shaped slide rails are fixedly connected to the top of the multiple support columns, and guide grooves are provided on the inner side of the arc-shaped slide rails. A sliding seat is slidably connected to the inner side of the guide groove. Two auxiliary wheels are rotatably connected to the bottom of the sliding seat. A servo motor is fixedly connected to one side of one of the sliding seats. A rotating rod is fixedly connected to the output end of the servo motor. The outer side of the rotating rod is rotatably connected to the inner side of the two sliding seats. Three sleeves are fixedly connected to the outer side of the rotating rod. Multiple grooves are opened on the outer side of the sleeves. A movable seat is rotatably connected to one end of the rotating rod. An electric push rod is fixedly connected to the bottom of the movable seat. A movable seat is fixedly connected to the bottom of the electric push rod. The bottom of the movable seat is hinged to the upper surface of the turntable. A drainage collection mechanism is provided inside the worktable.

[0009] As can be seen, in the above technical solution, the use of two arc-shaped slide rails allows the two rotating rods and multiple sleeves to adjust the distance between the two rotating rods according to the different diameters of different models of roller rings, so that there is a good force point between them and the roller rings, allowing the roller rings to rotate better under the rotation of the rotating rods. In addition, the grooves are used to collect some of the water in the cooling process, which can improve the heat resistance of the sleeves in the subsequent heat treatment, thereby improving the service life of the rotating support device.

[0010] Optionally, in one possible implementation, a pin is inserted into one side of the turntable, the bottom end of the pin is inserted into the inside of the insertion hole, a fixing ring is fixedly connected to the top of the worktable, and a plurality of balls are rotatably connected to the inside of the fixing ring, the top of the balls being slidably connected to the bottom of the turntable.

[0011] As can be seen, in the above technical solution, the turntable and two arc-shaped slide rails can be rotated through the insertion hole, thereby rotating the roller ring during the heating process, which facilitates heating different positions of the roller ring.

[0012] Optionally, in one possible implementation, the drainage collection mechanism includes a plurality of drainage holes located inside the turntable. A water storage tank is provided inside the workbench, and a pull frame is slidably connected to the inside of the water storage tank. A filter screen is fixedly connected to the inside of the pull frame. A drainage pipe is connected to one side of the water storage tank, and the drainage pipe passes through the inside of the workbench and extends to the outside of the workbench.

[0013] As can be seen, the above technical solution uses a filter screen to filter the cooled water to remove some impurities, allowing the water to be reused and reducing the waste of water resources.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a support mechanism, compared with the existing technology, the arc setting of two arc-shaped slide rails allows the two sets of rotating rods and sleeves to have good force distribution and support and rotation for roller rings of different diameters, so that the roller rings remain stable during the support and rotation process. In addition, multiple grooves are used to retain some water inside the sleeve, improving the heat resistance of the rotating support device and improving the stability and service life of the roller rings during hot working.

[0016] 2. By setting up a drainage collection mechanism, compared with the existing technology, the water after heat treatment is filtered by a filter screen, so that the water that cools the roller ring can be repeatedly recycled and reused, reducing water consumption and lowering the cost of roller ring heat treatment.

The two electric push rods 16 push the movable seat 15 to drive the rotating rod 13 and the two sliding seats 10 at the bottom to slide inside the arc-shaped slide rail 8. The two auxiliary wheels 11 on the outer side of the two sliding seats 10 can slide and guide the inner side of the guide groove 9, so that the two rotating rods 13 and the multiple sleeves 14 can slide in an arc shape outside the arc-shaped slide rail 8. Then, driven by the two servo motors 2 12, the two rotating rods 13 and the sleeves 14 can drive the roller ring to rotate.

[0029] Example 2

[0030] A pin 19 is inserted into one side of the turntable 6, with the bottom end of the pin 19 inserted into the inner side of the insertion hole 2. A fixing ring 20 is fixedly connected to the top of the workbench 1, and multiple balls 21 are rotatably connected to the inner side of the fixing ring 20. The top of the balls 21 is slidably connected to the bottom of the turntable 6. The drainage collection mechanism includes multiple drainage holes 22, which are located inside the turntable 6. A water storage tank 23 is provided inside the workbench 1, and a pull frame 24 is slidably connected to the inner side of the water storage tank 23.

A drain pipe 26 is connected to one side of the water storage tank 23, and the outer side of the drain pipe 26 penetrates the inner side of the workbench 1 and extends to... Outside the workbench 1, pull out the pin 19 on one side of the turntable 6, and then drive the rotating shaft 4 to rotate the turntable 6 through the servo motor 3. At the same time, multiple balls 21 on the top of the fixing ring 20 support the rotating turntable 6, so that the turntable 6 rotates smoothly. When the roller ring is cooled, the cooled water falls to the top of the filter screen 25 through the drain hole 22. After being filtered by the filter screen 25, the water collects at the bottom of the water storage tank 23, and then the water is output through the drain pipe 26 for secondary use. After that, pull the frame 24 from one side of the workbench 1 to clean the impurities accumulated on the surface of the filter screen 25.

[0031] Working principle of this utility model: This utility model designs a rotating support device for hot processing of roller rings, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, during the heat treatment of the roller ring, the distance between the two rotating rods 13 is first adjusted according to the diameter of the roller ring. Two electric push rods 16 push the movable seat 15, causing the rotating rods 13 and the two outer sliding seats 10 to slide on the outside of the arc-shaped slide rail 8. The auxiliary wheels 11 at the bottom of the two sliding seats 10 slide inside the guide groove 9, ensuring the two rotating rods 13 remain stable during their opposing movement. Simultaneously, the two arc-shaped slide rails 8 provide better support for the surface of the roller ring by the two rotating rods 13 and multiple sleeves 14, allowing the multiple sleeves 14 to form a good connection with the roller ring. A good stress point allows the two servo motors 12 to drive the rotating rod 13 to rotate the multiple sleeves 14, which in turn can better transmit power to the roller ring, thus enabling the roller ring to rotate smoothly. After that, the roller ring is heat-treated by the operator, and then the pin 19 is pulled out from one side of the turntable 6, so that the servo motor 3 can drive the turntable 6 to rotate with the assistance of the fixed ring 20 and multiple balls 21, so that the roller ring can rotate on its own. After rotating to the appropriate position, the pin 19 is reinserted into the inside of the turntable 6, and the bottom end of the pin 19 is inserted into the corresponding insertion hole 2 on the top of the worktable 1, so that the turntable 6 is kept fixed.

[0032] When cooling the roller ring after heat treatment, some water will enter the multiple grooves 18 inside the sleeve 14 after water mist is sprayed onto the roller ring. This water is retained inside the multiple sleeves 14, allowing the sleeve 14 to be cooled to a certain extent during subsequent heat treatment due to the water in the grooves 18. Afterward, the excess water flows into the multiple drain holes 22 inside the turntable 6, and then flows into the water storage tank 23 inside the worktable 1 for collection after being filtered by the filter screen 25. Finally, the pull frame 24 can be pulled out to collect the impurities on the surface of the filter screen 25. At the same time, the water accumulated in the water storage tank 23 is discharged through the drain pipe 26.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
