Description

Technical Field

[0001] The present invention relates to the technical field of mold assemblies, and more particularly to a fully welded ball valve auxiliary valve body mold. Background Art

[0002] The fully welded ball valve sub-valve body mold set can accurately locate the welding end connection of the sub-valve body through the closing of the upper mold and the lower mold. After positioning, the connection position is fully welded to ensure that each sub-valve body produced meets the design requirements. This high-precision replication capability is crucial to ensure the overall assembly accuracy and sealing performance of the ball valve.

[0003] In the existing published technical literature, the Chinese patent announcement number CN116060523A discloses a large-caliber combined welding pipe fitting die, which mainly uses a wedge block to drive two groups of profiling blocks to approach each other, and at the same time uses a transmission part to drive the air supply mechanism to perform an air suction operation, further ensuring that the two groups of profiling blocks are tightly connected, and performs an air blowing operation when the upper and lower molds are separated, which reduces the temperature of the inner wall of the groove and its surroundings, and can cool the components in the assembly seat, reflecting the linkage of the overall mold design, and to a certain extent can ensure the efficiency and safety of the pipe processing process. However, the mold has the following problems.

[0004] When the mold group is docking the pipe part connected to the ball valve sub-valve body, it is necessary to close the upper mold and the lower mold, and then position the connection part of the ball valve sub-valve body, and then perform the welding operation. During the positioning process, a certain extrusion force is required to achieve the welding operation. However, during the welding process, it is difficult to achieve precise limit control of the external extrusion distance of the ball valve sub-valve body, and it is also difficult to accurately limit the port part and the inner wall of the ball valve sub-valve body according to the specified extrusion distance. This leads to excessive extrusion or too shallow extrusion during the welding extrusion process of the ball valve sub-valve body, thereby reducing the accuracy of the mold group in welding the ball valve sub-valve body. Therefore, it is necessary to provide a fully welded ball valve sub-valve body mold. Summary of the invention

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention uses a peripheral precise limit welding mechanism, and the limit electric cylinder pushes the limit frame to move up, and the limit distance sensor senses the distance between the limit distance sensor and the slide frame. When the distance value sensed by the limit distance sensor is the same as the distance value set by the controller, the limit electric cylinder is closed by the controller, and the driving motor drives the linkage screw to rotate. The linkage screw rotates inside the slide frame, and the two sleeve blocks slide close to each other along the inner wall of the slide frame. The two limit clamps can squeeze and limit the two sides of the upper auxiliary valve body according to the specified extrusion force. In this way, when the lower mold group and the upper mold group are die-pressed and welded, when the downward movement distance of the slide frame is the limit welding distance sensed by the limit distance sensor, the bottom of the slide frame is limitedly supported by the limit frame, and the periphery between the lower auxiliary valve body and the upper auxiliary valve body can be accurately limited and welded, thereby greatly improving the welding accuracy of the mold group.

[0017] 2. The present invention utilizes a precise limit welding mechanism for the port to push the electric cylinder to push the support frame to the left, and two arc sleeves enter the internal position of the port between the lower auxiliary valve body and the upper auxiliary valve body. The transmission motor drives the connecting screw to rotate inside the support frame, and the arc sleeve drives the port distance sensor to move upward. When the distance value sensed by the port distance sensor is the same as the distance value set by the controller, the transmission motor is turned off by the controller, and the arc sleeve is used to perform precise limit welding on the port position of the upper auxiliary valve body, thereby greatly improving the accuracy of the mold group welding on the ball valve auxiliary valve body and realizing high-precision full welding operation.

[0018] 3. The present invention uses an internal precise limiting component to extrude the electric cylinder to push the slide ring upward, and the slide ring slides up along the outer wall of the rotating rod. The sleeve rod drives the hinge shaft away from the center point of the rotating rod, and the arc pressure plate fits against the inner wall of the upper auxiliary valve body. The rotating motor is started to drive the rotating rod to rotate forward 360 degrees and then reverse 360 ​​degrees. The arc pressure plate can perform rotational limiting welding along the welding inner wall position of the upper auxiliary valve body and the lower auxiliary valve body, avoiding the misalignment problem when the lower auxiliary valve body and the upper auxiliary valve body are connected, and greatly improving the accuracy of the mold assembly for welding the ball valve auxiliary valve body.

[0019] The interaction of the above multiple functions first enables the lower auxiliary valve body and the upper auxiliary valve body to be precisely limited in position welding at the periphery, then the upper auxiliary valve body port position is precisely limited in position welding through the arc sleeve, and finally the multiple arc pressure plates can be rotated and limited in position welding along the welding inner wall position of the upper auxiliary valve body and the lower auxiliary valve body. In summary, the problem of excessive extrusion between the lower auxiliary valve body and the upper auxiliary valve body during the welding extrusion process is avoided, thereby greatly improving the accuracy of the mold assembly welding the ball valve auxiliary valve body.

The two threaded sleeves 27 are both slidably connected to the support frame 24, and the outer wall of the threaded sleeve 27 and the inner wall of the support frame 24 are both smooth surfaces.

[0039] In this embodiment, as shown in the attached Figure 8-10As shown, the internal precise limit assembly includes a rotating motor 33 fixedly mounted on the inner wall of the lower mold assembly 1; the output end of the rotating motor 33 is fixedly connected to a rotating rod 34, and an extrusion electric cylinder 35 is fixedly mounted on one side of the outer wall of the rotating rod 34, and the output end of the extrusion electric cylinder 35 is fixedly connected to a slide ring 36, and the inner wall of the slide ring 36 is slidably connected to the outer wall of the rotating rod 34; the outer wall of the slide ring 36 is fixedly connected to a plurality of support shafts 37, and the outer wall of each support shaft 37 is rotatably connected to a sleeve rod 38, and the inner wall of the sleeve rod 38 is rotatably connected to a hinge shaft 39 at a position away from the support shaft 37.

[0040] A sleeve slider 40 is welded to one end of the hinge shaft 39, a connecting plate 42 is fixedly connected to one side of the sleeve slider 40, and an arc-shaped pressing plate 43 is fixedly installed at one end of the connecting plate 42, and a slide rod 41 is slidably connected to the inner wall of the sleeve slider 40; a guide frame 44 is installed at one end of the slide rod 41, and the sleeve slider 40 and the guide frame 44 are slidably connected, and multiple guide frames 44 are fixedly connected to the rotating rod 34. The center point of the hinge shaft 39 is higher than the center point of the support shaft 37, and multiple arc-shaped pressing plates 43 are arranged in a circular ring with equal spacing, and the cross section of the arc-shaped pressing plates 43 is an arc.

[0041] The method of using the fully welded ball valve auxiliary valve body mold of the present invention is as follows:

[0042] Step 1: During positioning, the lower auxiliary valve body 19 is inserted into the positioning ring 2, and the welding rod 20 is located on the upper surface of the lower auxiliary valve body 19. The welding rod 20 can be located on the upper surface of the lower auxiliary valve body 19. By starting the linkage electric cylinder 17, the linkage electric cylinder 17 drives the upper mold group 14 to move downward, and the upper mold group 14 moves downward stably along the outer wall of the plurality of guide columns 15. At the same time, the support sleeve 16 provides support force for the linkage electric cylinder 17, so that the upper mold group 14 is pressed on the upper surface of the upper auxiliary valve body 21, and at the same time, the upper mold group 14 drives the support plate 13 to move downward, and the support plate 13 drives the slide frame 7 to move downward, so that the upper auxiliary valve body 21 is positioned and squeezed, and the distance between the docking distance sensor 6 and the upper mold group 14 is sensed by the docking distance sensor 6. When the distance sensed by the docking distance sensor 6 is the same as the distance set by the controller 18, the linkage electric cylinder 17 is closed by the controller 18.

[0043] Step 2: When the peripheral precise limit welding is performed, the limit distance is set on the controller 18, and the positioning ring 2 is supported by the lower mold assembly 1, and the positioning ring 2 supports the sleeve plate 3, and the sleeve plate 3 provides a stable support force for the limit electric cylinder 4, so that the controller 18 starts the limit electric cylinder 4, and the limit electric cylinder 4 pushes the limit frame 5 to move up. At the same time, the limit frame 5 drives the limit distance sensor 45 to move up along the inner wall of the sleeve plate 3, and the distance between the limit distance sensor 45 and the slide frame 7 is sensed by the limit distance sensor 45. When the distance value sensed by the limit distance sensor 45 is the same as the distance value set by the controller 18, the limit electric cylinder 4 is closed by the controller 18.

[0044] At the same time, the controller 18 starts the drive motor 9, and the drive motor 9 drives the linkage screw 8 to rotate. The linkage screw 8 rotates inside the slide frame 7, and the two sleeve blocks 10 are driven to approach each other through the linkage screw 8. The two sleeve blocks 10 slide and approach each other along the inner wall of the slide frame 7. At the same time, the two sleeve blocks 10 respectively drive the two limit clamps 11 to approach each other, and the two limit clamps 11 are respectively squeezed at the positions on both sides of the upper auxiliary valve body 21. Torque sensing is performed on the torque sensor 31 through the linkage screw 8. At the same time, the slide frame 7 provides support force to the support block 32, and the support block 32 supports the torque sensor 31 and stably provides support force to the torque sensor 31. When the torque value sensed by the torque sensor 31 is the same as the torque value set by the controller 18, the drive motor 9 is turned off by the controller 18, and the drive of the drive motor 9 is stopped, so that the two limit clamps 11 can squeeze and limit the two sides of the upper auxiliary valve body 21 according to the specified squeezing force.

[0045] Step 3: When the port is precisely limited and welded, the sleeve bracket 22 is supported by the lower mold assembly 1, and the sleeve bracket 22 supports the push electric cylinder 23. The controller 18 starts the push electric cylinder 23, and the push electric cylinder 23 pushes the support frame 24 to move leftward. The support frame 24 drives the connecting screw 26 to move leftward. The connecting screw 26 makes the two threaded sleeves 27 move leftward, and the two threaded sleeves 27 respectively drive the two reinforcement plates 28 to move leftward. At the same time, the two reinforcement plates 28 respectively drive the two arc sleeves 29 to move leftward, and the two arc sleeves 29 respectively drive the two port distance sensors 30 to move leftward, so that the two arc sleeves 29 enter the internal position of the port between the lower auxiliary valve body 19 and the upper auxiliary valve body 21.

[0046] At the same time, the transmission motor 25 is started by the controller 18, and the transmission motor 25 drives the connecting screw 26 to rotate inside the support frame 24. The connecting screw 26 drives the two threaded sleeves 27 to move away from each other under the action of the thread transmission force, and the distance between the two threaded sleeves 27 becomes larger, and the two threaded sleeves 27 respectively drive the distance between the two reinforcement plates 28 to become larger. The two reinforcement plates 28 respectively drive the distance between the two arc sleeves 29 to become larger, so that the arc sleeve 29 moves up, and the other arc sleeve 29 moves down, and the arc sleeve 29 drives the port distance sensor 30 to move up, and the port distance sensor 30 senses the distance value between the port distance sensor 30 and the inner wall of the upper auxiliary valve body 21. When the distance value sensed by the port distance sensor 30 is the same as the distance value set by the controller 18, the transmission motor 25 is turned off by the controller 18, so that the arc sleeve 29 limits the port position on the inner wall of the upper auxiliary valve body 21 by a specified distance, and the other arc sleeve 29 limits the port position on the inner wall of the lower auxiliary valve body 19 by a specified distance.

[0047] Step 4: When the internal precise limit is applied, the extrusion electric cylinder 35 is started, and the extrusion electric cylinder 35 pushes the slide ring 36 to move upward, and the slide ring 36 slides along the outer wall of the rotating rod 34. At the same time, the slide ring 36 drives multiple support shafts 37 to move upward synchronously, and the support shaft 37 makes the bottom end of the sleeve rod 38 move upward, and the sleeve rod 38 drives the hinge shaft 39 away from the center point of the rotating rod 34, and the hinge shaft 39 drives the sleeve slider 40 away from the center point of the rotating rod 34, and the sleeve slider 40 slides along the outer wall of the slide rod 41. 40 slides along the inner wall of the guide frame 44, and the sleeve slider 40 drives the connecting plate 42 away from the center point of the rotating rod 34. The connecting plate 42 makes the arc pressure plate 43 away from the center point of the rotating rod 34. The arc pressure plate 43 fits on the inner wall of the upper auxiliary valve body 21, and the arc pressure plate 43 also fits on the inner wall of the lower auxiliary valve body 19. The arc pressure plate 43 can also fit on the inner wall of the welding rod 20. Multiple arc pressure plates 43 can be aligned with the inner wall position of the welding of the upper auxiliary valve body 21 and the lower auxiliary valve body 19, and the limit operation is performed according to the specified distance.

[0048] At the same time, the rotating motor 33 is started to drive the rotating rod 34 to rotate forward 360 degrees and then reverse 360 ​​degrees. The rotating rod 34 drives multiple guide frames 44 to rotate forward and backward. The guide frames 44 drive the sliding rod 41 to rotate forward and backward. The sliding rod 41 makes the sleeve sliding block 40 rotate forward and backward. The sleeve sliding block 40 drives the connecting plate 42 to rotate forward and backward. The connecting plate 42 makes the arc pressure plate 43 rotate forward and backward. The arc pressure plate 43 can be rotated and limited along the inner wall position of the welding between the upper auxiliary valve body 21 and the lower auxiliary valve body 19.

[0049] Step 5: When welding is limited, the controller 18 supplies power to the hot melt heater 12, the hot melt heater 12 heats, and the sleeve bracket 22 supports the upper sub-valve body 21, so that the hot melt heater 12 heats the welding rod 20, so that the welding rod 20 is welded and hot-melted at the connection between the lower sub-valve body 19 and the upper sub-valve body 21. At the same time, the controller 18 starts the linkage electric cylinder 17 to move downward, the linkage electric cylinder 17 pushes the upper mold assembly 14 to move downward, and the upper mold assembly 14 pushes the upper sub-valve body 21 downward to squeeze the welding rod 20, and the welding rod 20 is hot-melted and squeezed on the lower sub-valve body 19. At the same time, the upper mold group 14 drives the support plate 13 to move downward, the support plate 13 drives the slide frame 7 to move downward, the slide frame 7 drives the linkage screw 8 to move downward, the linkage screw 8 drives the two sleeve blocks 10 to move downward synchronously, the two sleeve blocks 10 respectively drive the two limit clamps 11 to move downward, the two limit clamps 11 squeeze the upper auxiliary valve body 21 to move downward, and the edge position of the upper auxiliary valve body 21 is limited downward welding, when the downward movement distance of the slide frame 7 is the limit welding distance sensed by the limit distance sensor 45, the bottom of the slide frame 7 is limitedly supported by the limit frame 5 to prevent the slide frame 7 from moving downward beyond the limit.

[0050] At the same time, the upper auxiliary valve body 21 is squeezed on the outer wall of the arc sleeve 29, and the arc sleeve 29 is used to accurately limit the position of the port of the upper auxiliary valve body 21, so that the sleeve bracket 22 supports the push electric cylinder 23, and the push electric cylinder 23 supports the support frame 24, and the support frame 24 provides a stable support force for the connecting screw 26. At the same time, the connecting screw 26 supports the threaded sleeve block 27, and the threaded sleeve block 27 supports the reinforcement plate 28, and the reinforcement plate 28 provides a stable support force for the arc sleeve 29. Multiple arc pressure plates 43 are welded along the inner wall position of the upper auxiliary valve body 21 and the lower auxiliary valve body 19 to achieve rotational limit welding, ensuring that the upper auxiliary valve body 21 and the lower auxiliary valve body 19 can be accurately fully welded according to the specified distance.
