Description

Technical Field

[0001] The utility model relates to the technical field of spherical valve forging devices, in particular to a spherical valve forging device with high stability. Background Art

[0002] A ball valve is a valve whose opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Among them, the hard-sealed V-type ball valve has a strong shear force between its V-shaped ball core and the metal valve seat with hard alloy overlay, which is particularly suitable for media containing fibers, tiny solid particles, etc.

[0003] For example, announcement number CN216441697U discloses a valve ball processing device, which includes: a support plate and a discharge port provided on the support plate, a support platform fixedly mounted on the support plate, a fixed block provided on the support plate, an opening provided on the fixed block, a fixed plate fixedly connected to the support plate, a drill provided on the fixed plate for drilling holes, and a collection bucket installed below the support plate; two sliding blocks, both of which are slidably connected to the support plate, a slide groove provided on the support plate for connecting the sliding blocks, and a first magnet and a scraper fixedly connected to the sliding blocks. According to the utility model, waste materials can flow along the inclined surface, through the discharge port, and fall into the collection bucket, eliminating the need for manual cleaning of the waste materials. Cleaning is more convenient, quicker, and less time-consuming, making it more conducive to subsequent drilling of other valve balls.

[0004] The valve ball processing device similar to the above application also has the following shortcomings:

[0005] 1. The ball valve cannot be fixed in a limited position. During the forging process, due to the poor fixing effect of the ball valve, the ball valve may deviate, causing the forging position to change, reducing the forging accuracy, resulting in material waste and increased costs.

[0006] 2. If you want to adjust the position of the ball valve during the forging process, you need to close the device and then adjust it manually, which increases labor intensity and reduces forging speed.

[0007] Therefore, it is necessary to invent a spherical valve forging device with high stability to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a ball valve forging device with high stability, so as to solve the problem that the ball valve cannot be limited and fixed. During the forging process, due to the poor fixing effect of the ball valve, the ball valve deviates, resulting in changes in the forging position, reduced forging accuracy, waste of materials and increased costs.

[0012] Preferably, the front bottom of the support column is connected to the rear outer wall of the forging shell, and the forging hammer is arranged directly above the spherical groove.

[0013] Preferably, four guide rods are installed at the bottom of the mounting seat, and buffer springs are provided on the outer sides of the four guide rods, and the tops of the buffer springs are fixedly connected to the bottom of the mounting seat.

[0014] Preferably, the outer side of the guide rod is slidably connected to the inner side of the buffer groove, and the bottom of the buffer spring is connected to the inner top of the forged shell.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1 、 Figure 2 , Figure 3 and Figure 4As shown, a ball valve forging device with high stability includes a forging shell 1, a forging component 2 and a limiting component 3. The rear outer wall of the forging shell 1 is installed with a forging component 2 for forging the ball valve, and the inner side of the forging shell 1 is connected with a limiting component 3 for fixing the ball valve. The limiting component 3 includes a mounting seat 31, the outer wall of the mounting seat 31 is connected to the inner wall of the forging shell 1, and the top side of the mounting seat 31 is provided with a mounting groove 32 and a spherical groove 33, the spherical groove 33 is arranged at the midpoint of the mounting groove 32, and a fixing plate 34 is installed on the side of the mounting groove 32 close to the forging shell 1, and a fixing groove 341 is provided on the top side of the fixing plate 34, and a servo motor is installed on the inner side of the fixing groove 341. The outer end of the servo motor 35 is mounted on the rotating shaft 36, the outer end of the rotating shaft 36 is connected to the second hydraulic cylinder 37, the outer end of the second hydraulic cylinder 37 is mounted with a telescopic rod 38, the outer end of the telescopic rod 38 is mounted with a clamping plate 39, the inner bottom of the forged shell 1 is provided with four buffer grooves 11, the bottom of the mounting seat 31 is mounted with four guide rods 311, the outer sides of the four guide rods 311 are provided with buffer springs 312, the top of the buffer spring 312 is fixedly connected to the bottom of the mounting seat 31, the outer side of the guide rod 311 is slidably connected to the inner side of the buffer groove 11, the bottom of the buffer spring 312 is connected to the inner top of the forged shell 1, and the clamping surface of the clamping plate 39 is provided with an anti-slip pad 391;

[0027] Its operation is as follows: after the ball valve is placed inside the ball groove 33, by starting the second hydraulic cylinder 37, the telescopic rod 38 drives the clamping plate 39 to move toward the side of the ball valve. The two clamping plates 39 contact the two sides of the ball valve respectively to clamp and fix the ball valve. The setting of the anti-slip pad 391 can increase the friction force, prevent the ball valve from sliding, improve stability, and protect the outer wall of the ball valve to reduce damage during the forging process. When the position of the ball valve needs to be adjusted, the two servo motors 35 are started at the same time, and the two rotating shafts 36 rotate in opposite directions, driving the ball valve to rotate to the forging position. When the position is upward, the servo motor 35 is turned off and the rotation is stopped. During the forging process of the ball valve, the ball valve is often subjected to downward impact force. Long-term use can easily cause damage to the device and reduce its service life. When the guide rod 311 and the buffer spring 312 are subjected to impact force, the guide rod 311 moves downward to the inside of the buffer groove 11, and the buffer spring 312 is compressed, which can buffer the impact force and reduce damage to the device. After the impact force disappears, the buffer spring 312 automatically resets, and the guide rod 311 moves upward to leave the buffer groove 11, thereby increasing the flexibility of the device.

[0028] like Figure 1 and Figure 2As shown, the forging assembly 2 includes a support column 21, a first hydraulic cylinder 22, a lifting rod 23 and a forging hammer 24. The first hydraulic cylinder 22 is installed on the top of the support column 21, and the lifting rod 23 is installed at the bottom end of the first hydraulic cylinder 22. The forging hammer 24 is installed at the bottom of the lifting rod 23. The front bottom of the support column 21 is connected to the rear outer wall of the forging shell 1, and the forging hammer 24 is set directly above the spherical groove 33.

[0029] The specific operation is as follows: after the ball valve is installed, the first hydraulic cylinder 22 is started, and the lifting rod 23 drives the forging hammer 24 to descend, applying impact force to the ball valve in a short time. The forging hammer 24 repeats the above operation on the ball valve multiple times, and the forging position of the ball valve is adjusted by the servo motor 35 to achieve the forging shaping effect and improve the forging efficiency.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual Figures 1 to 4 When using the utility model, after the ball valve is placed inside the ball groove 33, by starting the second hydraulic cylinder 37, the telescopic rod 38 drives the clamping plate 39 to move toward the side of the ball valve. The two clamping plates 39 contact the two sides of the ball valve respectively to clamp and fix the ball valve. The setting of the anti-slip pad 391 can increase the friction force, prevent the ball valve from sliding, improve stability, and protect the outer wall of the ball valve, reducing damage during the forging process. Then start the first hydraulic cylinder 22, and the lifting rod 23 drives the forging hammer 24 to descend, applying impact force to the ball valve in a short time. The forging hammer 24 repeats the above operation on the ball valve multiple times. When the position of the ball valve needs to be adjusted, the two servo motors 35 are started at the same time, and the two rotating shafts 36 rotate in opposite directions, driving the ball valve to rotate. When it rotates to the forging position upward, the servo motor 35 is turned off and the rotation is stopped. During the forging process, the ball valve is continuously subjected to downward impact force, and the guide rod 311 moves downward to the inside of the buffer groove 11. The buffer spring 312 is compressed, which can buffer the impact force and reduce damage to the device. After the impact force disappears, the buffer spring 312 will automatically reset, and the guide rod 311 moves upward to leave the buffer groove 11, increasing the flexibility of the device. The above is the working principle.
