[0003] Pressure vessel tube sheets are large in size and are processed using giant forging equipment. The forging process requires continuous position adjustment and rotation. Currently, a clamping trolley is used to assist in the rotation and displacement of the pressure vessel tube sheet by hydraulically controlling the clamps. While controlling the hydraulic clamps to lift, move left and right, the clamping trolley also needs to move the vehicle body forward and backward simultaneously, requiring multi-directional adjustment and control. The clamping trolley requires high operator skills and is difficult for new personnel to learn. Summary of the Invention

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a special equipment for forging high-performance pressure vessel tube sheets, including: a main forging base 1, an upper lifting forging frame 2, and a lower forging base 3. A drive motor 101 is fixedly installed on the top of the main forging base 1, and a drive gear 102 is fixedly installed on the main shaft of the drive motor 101. Side grooves 103 are provided on both sides of the main forging base 1. The upper lifting forging frame 2 is provided above the main forging base 1. Lifting slide columns 201 are vertically slidable through the four corners of the upper lifting forging frame 2. The top of the upper lifting forging frame 2 is fixedly connected to a forging hydraulic cylinder 202. The forging hydraulic cylinder 202 is fixedly connected to an upper support frame 203. The lower forging base 3 is provided below the upper lifting forging frame 2. A transfer frame 301 is rotatably installed at the bottom of the lower forging base 3. An outer connecting frame 302 is arranged in a circular array on the outer side of the transfer frame 301. The connecting frame 302 and the outer connecting rod 303 are rotatably connected by their respective shafts. The tail end of the outer connecting rod 303 is rotatably connected by its corresponding shaft to the side support frame 304. The outer connecting frame 302 and the telescopic rod of the side telescopic cylinder 305 are rotatably connected by their respective shafts. The tail end of the side telescopic cylinder 305 is rotatably connected by its corresponding shaft to the main forging base 1. The side telescopic cylinder 305 extends and pushes the intermediate transfer frame 301 and the outer connecting frame 302 to rotate. The intermediate transfer frame 301 drives the side support frame 304 to move closer to or further away from the lower forging base 3 through the outer connecting rod 303. The top surface of the side support frame 304 is in contact with the bottom surface of the lower forging base 3. The bottom of the side support frame 304 slides along the side groove 103. The side support frame 304 moves to the bottom of the lower forging base 3 to provide support during forging, ensuring the support force of the lower forging base 3 and ensuring the stability of the lower forging base 3 during the forging process.

[0029] In this embodiment, the drive gear 102 is meshed with the lower forging seat 3, the lower end of the lifting slide column 201 is fixedly connected to the main forging base 1, and the top end of the lifting slide column 201 is fixedly connected to the upper support frame 203. The drive gear 102 meshes and drives the lower forging seat 3 and the forging on the top to rotate synchronously in a circumferential direction. The part of the pressure vessel tube sheet component below the upper lifting forging frame 2 changes, thereby adjusting the forging position of the pressure vessel tube sheet component and reducing the need for adjustment by a jig carriage.

[0030] In this embodiment, the bottom center of the transfer frame 301 is rotatably connected to the main forging base 1. When the transfer frame 301 rotates, the side support frame 304 moves horizontally along the side groove 103. The side support frame 304 moves first and separates from the lower forging base 3. The lower forging base 3 and the side support frame 304 no longer contact each other, reducing the friction between the rotation of the lower forging base 3 and the side support frame 304, and reducing the rotational resistance of the lower forging base 3.

[0031] In Example 2, based on Example 1, the lower forging seat 3 and the intermediate transfer frame 301 can rotate circumferentially and move axially. The inner side of the side support frame 304 is a sloped structure. As the side support frame 304 moves closer to the lower forging seat 3, it guides the lower forging seat 3 to move upward through the slope, reducing the pressure on the rotating bearing between the lower forging seat 3 and the intermediate transfer frame 301 during forging. After the side support frame 304 and the lower forging seat 3 separate, the lower forging seat 3 falls and rotates along the rotating bearing between the lower forging seat 3 and the intermediate transfer frame 301, reducing the resistance to rotation.

[0032] The working principle of this embodiment is as follows: The main forging base 1 is connected and fixed to the ground. The pressure vessel tube sheet component to be forged is placed on top of the lower forging base 3. The forging hydraulic cylinder 202 extends to support the upper lifting forging frame 2, which presses down along the lifting slide column 201. The upper lifting forging frame 2 and the pressure vessel tube sheet component on top of the lower forging base 3 come into contact for forging. Through forging, the pressure vessel tube sheet component is compressed, reducing internal voids in the metal and increasing the strength of the pressure vessel tube sheet component. The pressure vessel tube sheet component is gradually forged from a cylindrical shape into a disc-shaped structure. During the forging process, the position of the pressure vessel tube sheet component needs to be continuously adjusted to maintain uniform forging position. The pressure vessel tube sheet component has a special... The special vehicle is used for moving and conveying and adjusting the vertical position. However, when it is necessary to rotate to adjust the position, the drive motor 101 drives the drive gear 102 to rotate. The drive gear 102 meshes and drives the lower forging seat 3 and the top forging to rotate synchronously in a circumferential direction. The part of the pressure vessel tube plate component below the upper lifting forging frame 2 changes, thereby realizing the adjustment of the forging position of the pressure vessel tube plate component. This reduces the need for adjustment through a jig car. Compared with the operation of a complex jig car, the rotation of the lower forging seat 3 has lower technical requirements for operators and is simpler to operate. It is conducive to the learning of newcomers, reduces the operation procedures of jig car personnel, and reduces the learning pressure of jig car personnel.

[0033] When the lower forging seat 3 needs to rotate, the side telescopic cylinder 305 extends to push the intermediate frame 301 and the outer connecting frame 302 to rotate. The intermediate frame 301 pushes the side support frame 304 to move away from the lower forging seat 3 through the outer connecting rod 303. The side support frame 304 moves first and separates from the lower forging seat 3. The lower forging seat 3 and the side support frame 304 no longer contact each other, reducing the friction between the rotation of the lower forging seat 3 and the side support frame 304, and reducing the rotation resistance of the lower forging seat 3. After the lower forging seat 3 has finished rotating, the side telescopic cylinder 305 shortens, and the outer connecting rod 303 pulls the side support frame 304 to the bottom of the lower forging seat 3. The side support frame 304 moves to the bottom of the lower forging seat 3 to perform support operation during forging, ensuring the support force of the lower forging seat 3 and ensuring the stability of the lower forging seat 3 during the forging process.
