Description

Technical Field

[0001] This utility model relates to the field of mold lifting technology, and in particular to a mold lifting mechanism for a ring rolling mill. Background Technology

[0002] The die lifting mechanism of a ring rolling mill is a core functional component of the equipment, serving as a key execution unit for achieving rapid die loading and unloading, precise height adjustment, and efficient switching between processing stations. This mechanism is widely used in automated production scenarios for high-precision ring parts, such as bearing manufacturing, flange processing, and gear ring forming.

[0003] In existing vertical ring rolling mill mold lifting mechanisms, traditional clamping and lifting functions mostly adopt a split structure. The clamping action relies on manual adjustment or simple cylinder drive, making it difficult to achieve rapid adaptive clamping of molds of different sizes. Moreover, the clamping force is not uniform, which can easily cause the mold to tilt or fall off during the lifting process. On the other hand, the guide structure in the lifting process mostly adopts the form of sliding friction, which has high frictional resistance and severe wear. After long-term use, it is easy to experience movement jamming or decreased accuracy. Especially in the vertical lifting process, the lack of effective bidirectional guide support results in insufficient stability of the clamping plate during lifting and horizontal movement, affecting processing efficiency and equipment reliability. In order to address this technical problem, this application proposes a ring rolling mill mold lifting mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ring rolling mill mold lifting mechanism. Through the mechanical linkage design of a motor-driven bidirectional lead screw, the synchronous opposite movement of two clamping plates is achieved, which can quickly and stably clamp molds of different sizes. The support sleeve is slidably connected to the support rod through pulleys to form a vertical lifting guide system. When the clamping plate moves horizontally with the moving sleeve, the sliding tenon restricts the lateral displacement of the fixed plate two, ensuring the linearity of the clamping action.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A ring rolling mill mold lifting mechanism includes a base plate, a support frame fixedly connected to the top of the base plate, support rods fixedly connected to both ends of the support frame, a support sleeve connected to the inner wall of the support frame via a lifting assembly, the rear end of the support sleeve connected to the support rod via a sliding assembly, a bidirectional lead screw rotatably connected to the inner wall of the support sleeve, two movable sleeves connected to the outer wall of the bidirectional lead screw via threaded sleeves, a fixing plate second fixedly connected to the front end of each of the two movable sleeves, a clamping plate fixedly connected to the front end of each of the two fixing plates second, and the rear ends of each of the two fixing plates second connected to the support sleeve via a stabilizing assembly.

[0007] Furthermore, the lifting assembly includes an electric push rod located on the inner wall of the support frame. A connecting rod is fixedly connected to the top of the electric push rod, and fixing blocks are fixedly connected to both ends of the connecting rod. The front ends of the two fixing blocks are fixedly connected to the rear end of the support sleeve.

[0008] Furthermore, the sliding assembly includes a fixed plate located at the rear end of the support sleeve, with a pulley rotatably connected to the inner circumference of the fixed plate, and the outer wall of the pulley slidably connected to the outer wall of the support rod.

[0009] Furthermore, the stabilizing component includes a movable plate located at the rear end of the two fixed plates, and each of the two movable plates has a sliding tenon fixedly connected to its inner circumference, and the outer walls of the two sliding tenons are slidably connected to the inner wall of the support sleeve.

[0010] Furthermore, handrails are fixedly connected to the rear ends of both support rods.

[0011] Furthermore, wheels are mounted on the bottom end of the base plate via a wheel frame.

[0012] Furthermore, a motor is mounted on the left end of the support sleeve via a fixing bracket, and the motor drive end is fixedly connected to the left end of the bidirectional lead screw.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the mechanical linkage design of the motor-driven bidirectional lead screw realizes the synchronous opposite movement of the two clamping plates, which can quickly and stably clamp molds of different sizes. After the clamping action is completed, the electric push rod directly drives the support sleeve to lift as a whole, integrating the clamping mechanism and the lifting mechanism into the same system, avoiding the cumbersome operation of the traditional split structure and improving efficiency.

[0015] 2. In this utility model, the support sleeve is connected to the support rod by a pulley to form a vertical lifting guide system. The rolling friction of the pulley replaces the sliding friction of the traditional slider, which can reduce wear. The rigid support of the support rod can also reduce the shaking during the lifting process. The sliding tenon and the sliding groove on the inner wall of the support sleeve form a horizontal guide structure. When the clamping plate moves horizontally with the moving sleeve, the sliding tenon restricts the lateral displacement of the fixed plate two, ensuring the linearity of the clamping action.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a ring rolling mill mold lifting mechanism, including a base plate 1, a support frame 3 fixedly connected to the top of the base plate 1, support rods 4 fixedly connected to both ends of the support frame 3, a support sleeve 8 connected to the inner wall of the support frame 3 through an electric push rod 5, a connecting rod 6 and a fixing block 7, the rear end of the support sleeve 8 being connected to the support rods 4 through a fixing plate 9 and a pulley 10, a bidirectional lead screw 13 rotatably connected to the inner wall of the support sleeve 8, two movable sleeves 14 connected to the outer wall of the bidirectional lead screw 13 through a threaded sleeve, a fixing plate 15 fixedly connected to the front end of each of the two movable sleeves 14, a clamping plate 16 fixedly connected to the front end of each of the two fixing plates 15, and the rear ends of each of the two fixing plates 15 being connected to the support sleeve 8 through a movable plate 17 and a sliding tenon 18;

[0024] Specifically, the motor 12 is started, and its drive end drives the bidirectional lead screw 13 to rotate. Since the threads at both ends of the bidirectional lead screw 13 turn in opposite directions, the two moving sleeves 14 move in opposite directions along the axis of the lead screw under the action of the threaded sleeves, pushing the clamping plate 16 to clamp the mold through the fixed plate 2 15. During this process, the moving plate 17 at the rear end of the fixed plate 2 15 drives the sliding tenon 18 to slide in the groove on the inner wall of the support sleeve 8. The cooperation between the sliding tenon 18 and the groove forms a horizontal guiding constraint, effectively preventing the clamping plate 16 from shifting or shaking during movement, ensuring clamping accuracy. After confirming that the mold is firmly clamped, the electric push rod 5 is started again to continue pushing the support sleeve 8 upward until the mold reaches the required working height. Throughout the process, the sliding guidance of the pulley 10 and the support rod 4, and the limiting effect of the sliding tenon 18 and the support sleeve 8, together ensure the smoothness and reliability of the movement.

[0025] Reference Figures 2-4 The electric push rod 5 is located on the inner wall of the support frame 3. The top of the electric push rod 5 is fixedly connected to the connecting rod 6. The left and right ends of the connecting rod 6 are fixedly connected to the fixing blocks 7. The front ends of the two fixing blocks 7 are fixedly connected to the rear end of the support sleeve 8. The fixing plate 1 9 is located at the rear end of the support sleeve 8. The inner circumference of the fixing plate 1 9 is rotatably connected to the pulley 10. The outer wall of the pulley 10 is slidably connected to the outer wall of the support rod 4. The moving plate 17 is located at the rear end of the two fixing plates 15. The inner circumference of the two moving plates 17 is fixedly connected to the sliding tenon 18. The outer wall of the two sliding tenon 18 is slidably connected to the inner wall of the support sleeve 8. The rear ends of the two support rods 4 are fixedly connected to the handrail 11. The bottom end of the base plate 1 is equipped with a wheel 2 through a wheel frame. The left end of the support sleeve 8 is equipped with a motor 12 through a fixing frame. The drive end of the motor 12 is fixedly connected to the left end of the bidirectional lead screw 13.

[0026] Specifically, the operator holds the handle 11 and uses the wheels 2 at the bottom of the base plate 1 to move the entire device to the target position. The wheels 2 move flexibly to achieve rapid positioning. The electric push rod 5 is then activated, its piston rod extending and pushing the connecting rod 6 upwards. The fixing blocks 7 at both ends of the connecting rod 6 cause the support sleeve 8 to rise vertically along the inner wall of the support frame 3. Simultaneously, the fixing plate 9 at the rear end of the support sleeve 8 causes the pulley 10 to slide synchronously on the outer wall of the support rod 4. The rolling cooperation between the pulley 10 and the support rod 4 significantly reduces frictional resistance, ensuring the support sleeve 8 rises and falls smoothly until the clamping plate 16 moves to a height aligned horizontally with the mold.

[0027] Working principle: When the mold needs to be lifted, hold the handle 11 and move the device to the appropriate position using the wheels 2. Then, start the electric push rod 5 to move the clamping plate 16 to the same horizontal line as the mold. When the clamping plate 16 moves, it will drive the pulley 10 to slide on the support rod 4 through the support sleeve 8 and the fixed plate 1 9, which will enhance the stability of the clamping plate 16 when it is raised and lowered. Then, start the motor 12 to drive the double-acting screw 13 to rotate. When the double-acting screw 13 rotates, it will drive the two fixed plates 15 to move in opposite directions through the moving sleeve 14, thereby clamping the mold through the clamping plate 16. When the two clamping plates 16 move relative to each other, the fixed plate 15 can drive the moving plate 17 and the sliding tenon 18 to move, which can enhance the stability of the clamping plate 16 when it moves horizontally. After clamping, start the electric push rod 5 again to lift the mold.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
