Technical Field

[0001] The utility model relates to the technical field of ring rolling machines, in particular to a reinforced guide post structure for the guide wheels of a ring rolling machine. Background Art

[0002] A ring rolling machine is a device used for forging large flange rings and is used to produce various seamless ring forgings of annular mechanical parts with various shapes and sizes, such as bearing rings, gear rings, flanges, hubs, thin-walled cylindrical parts, wind power flanges, high-neck flanges, etc. The guide wheel arm in the ring rolling machine is an important component in the ring rolling machine, mainly used to guide and support the correct position of the rotating part, ensuring the stability and efficiency of the ring rolling machine during operation;

[0003] When the existing ring rolling machine is working, since the workpiece rotates continuously and is driven and processed by the ring rolling machine, it may cause the guide wheel arm in the ring rolling machine to move up and down or vibrate during the working movement and guiding, thereby increasing the material ratio and resulting in the flange size and concentricity during processing not meeting the set dimensions. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A reinforced guide post structure for the guide wheels of a ring rolling machine, comprising: a U-shaped block, a guide arm is slidably connected inside the U-shaped block, the top of the guide arm is connected to an inclined rod through a trunnion, the other end of the inclined rod is connected to a limiting mechanism through a trunnion, the top of the U-shaped block is connected to a grooved block, and a plurality of card slots are evenly arranged inside the grooved block.

[0006] The limiting mechanism includes a slider, the slider is slidably connected to the grooved block, a clamping block is slidably connected inside the slider, a T-shaped plate is slidably connected to the top of the slider, both ends of the left side of the T-shaped plate are connected to a connecting rod through a hinge, the other end of the connecting rod is connected to the clamping block through a hinge, a limiting plate is connected to the top of the slider, and a cylinder is connected to the inner top of the limiting plate, and the cylinder is connected to the T-shaped plate.

[0007] Preferably, both ends of the bottom of the U-shaped block are equipped with first mounting plates, and bolts are evenly arranged on the top of the first mounting plates. The first mounting plates facilitate the assembly of the U-shaped block.

[0008] Preferably, a second mounting plate is connected to the left side of the guiding arm, and bolts are evenly distributed on the outer part of the second mounting plate, which facilitates the installation of the guiding arm.

[0009] Preferably, a T-shaped groove is formed inside the slider, and the T-shaped groove is slidably connected to the T-shaped plate. The T-shaped groove facilitates the movement of the T-shaped plate and can guide the T-shaped plate to move linearly.

[0010] Preferably, a spring is connected to the left side of the clamping block, and the spring is connected to the slider. The spring can drive the clamping block to quickly return to its original position.

[0011] Preferably, a trapezoidal block is slidably connected inside the clamping block, and a return spring is connected between the trapezoidal block and the clamping block. The trapezoidal block can enable the clamping block to automatically cooperate with the clamping groove to limit the return of the slider.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a technical solution. Please refer to Figure 1 , Figure 2 and Figure 3 , a reinforcing guide post structure for the guide wheel of a ring rolling machine, including: a U-shaped block 1, the U-shaped block 1 can be fixed outside the hydraulic system. Both ends of the bottom of the U-shaped block 1 are equipped with first assembly plates 11, and bolts are evenly arranged on the top of the first assembly plates 11. The first assembly plates 11 facilitate the assembly of the U-shaped block 1. A guiding arm 2 is slidably connected inside the U-shaped block 1. The guiding arm 2 can guide the guide wheel. The left side of the guiding arm 2 is connected with a second assembly plate 21.

[0022] Bolts are evenly arranged outside the second assembly plate 21. The second assembly plate 21 facilitates the installation of the guiding arm 2. The top of the guiding arm 2 is connected with an inclined rod 3 through a trunnion. The inclined rod 3, the slotted block 4 and the card slot 5 can increase the stability of the guiding arm 2 during movement. The other end of the inclined rod 3 is connected with a limiting mechanism 6 through a trunnion. The top of the U-shaped block 1 is connected with a slotted block 4, and card slots 5 are evenly arranged inside the slotted block 4.

[0023] Please refer to Figure 4 and Figure 5 , the limiting mechanism 6 includes a slider 61. The slider 61 can limit the inclined rod 3. The slider 61 is slidably connected with the slotted block 4. A clamping block 62 is slidably connected inside the slider 61. The clamping block 62 can be inserted into the card slot 5 to prevent the slider 61 from moving. A T-shaped plate 64 is slidably connected to the top of the slider 61. Both ends of the left side of the T-shaped plate 64 are connected with a connecting rod 65 through a hinge. The connecting rod 65 and the T-shaped plate 64 cooperate to control the movement of the clamping block 62.

[0024] The other end of the connecting rod 65 is connected to the clamping block 62 through a hinge. A limiting plate 67 is connected to the top of the slider 61. The inner top of the limiting plate 67 is connected to a cylinder 66. The cylinder 66 can control the movement of the T-shaped plate 64. The cylinder 66 is connected to the T-shaped plate 64. A T-shaped groove 68 is formed inside the slider 61, and the T-shaped groove 68 is slidably connected to the T-shaped plate 64. The T-shaped groove 68 facilitates the movement of the T-shaped plate 64 and can guide the T-shaped plate 64 to move in a straight line.

[0025] A spring is connected to the left side of the clamping block 62, and the spring is connected to the slider 61. The spring can drive the clamping block 62 to quickly return to its original position. A trapezoidal block 69 is slidably connected inside the clamping block 62, and a return spring 63 is connected between the trapezoidal block 69 and the clamping block 62. The trapezoidal block 69 can enable the clamping block 62 to automatically cooperate with the clamping groove 5 to limit the return of the slider 61. At the same time, the return spring 63 can guide the clamping block 62. At the same time, when the cylinder 66 moves upward, it can drive the clamping block 62 to completely pop out of the inside of the slider 61, so that the clamping block 62 is completely inserted into the inside of the clamping groove 5 to limit the position of the limiting mechanism 6.

[0026] In this solution, first, the C-shaped block 1 is assembled on the top of the hydraulic system in the guide wheel arm through the first assembly plate 11, and the second assembly plate 21 is assembled outside the guide wheel in the guide wheel arm. When the guide wheel arm is working, it is limited by the cooperation of the C-shaped block 1 and the guide arm 2 to prevent the guide wheel arm from generating vertical displacement during work. At the same time, when the guide arm 2 moves, it drives the inclined rod 3 to move. The inclined rod 3 cooperates with the limiting mechanism 6 to form a triangle with the guide arm 2, the C-shaped block 1, and the grooved block 4, thereby improving the stability of the device during work and preventing the guide arm 2 from completely moving out of the inside of the C-shaped block 1, resulting in instability and easy shaking. At the same time, when the slider 61 moves inside the grooved block 4, through the cooperation of the clamping block 62 and the clamping groove 5, it prevents the guide arm 2, the inclined rod 3, and the limiting mechanism 6 from returning during movement, further increasing the stability of the C-shaped block 1 and the guide arm 2, and preventing the guide wheel arm from returning during movement. At the same time, it can also position the guide wheel arm after the movement is completed, and then accurately process the workpiece with the required dimensions. After the workpiece is processed, the cylinder 66 is started to drive the T-shaped plate 64 to move, and then the clamping block 62 is retracted into the inside of the slider 61, so that the guide wheel arm and the guide arm 2 return to their original positions;

[0027] When the guide wheel arm in the ring rolling machine is working, the added guide arm 2 and diagonal rod 3 automatically limit and guide the guide wheel arm, preventing the guide wheel arm from moving up and down during operation. Additionally, with the added slotted block 4, card slot 5, limiting mechanism 6, and diagonal rod 3, the device forms a triangular shape when guiding the guide wheel arm, thereby improving the stability of the device during operation and preventing the guide arm 2 from completely moving out of the inside of the U-shaped block 1, which could lead to instability and easy shaking. At the same time, when the slider 61 moves inside the slotted block 4, the cooperation between the clamping block 62 and the card slot 5 prevents the guide arm 2, diagonal rod 3, and limiting mechanism 6 from returning during movement, further increasing the stability of the U-shaped block 1 and the guide arm 2. It can also position the guide wheel arm after movement is completed, enabling the accurate machining of workpieces with the required dimensions.
