Description

Technical Field

[0001] This utility model relates to the field of hydraulic water expansion machine technology, specifically a hydraulic water expansion machine with an automatic unloading structure. Background Technology

[0002] Hydraulic water expanders are a commonly used machining equipment, mainly used for operations such as tube expansion and pipeline expansion. The working principle of hydraulic water expanders is based on the principle of liquid volume expansion. When water is injected into the pipeline, the expansion of water volume will increase the diameter of the pipeline if the pipeline material remains unchanged, thereby achieving the effect of tube expansion and pipeline expansion. However, existing hydraulic water expanders still have certain defects in use.

[0003] In the existing technology, the hydraulic water expansion machine is a high-efficiency, environmentally friendly and easy-to-operate tube expansion equipment that can expand various pipes. Water can be injected into the pipe through the injection tube, and the pipe is expanded and shaped by the pipe forming mold. During the use of the hydraulic water expansion machine, manual unloading is required. Manual unloading requires contact with the pipe. If the operator is not careful or the equipment malfunctions, it may cause injury to the operator, which poses a certain safety risk. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic water expander with an automatic unloading structure to solve the problem mentioned in the background art that the hydraulic water expanders currently on the market are not easy to automatically unload.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic expansion machine with an automatic unloading structure, comprising: a base body, a control box, a pipe forming mold, a hydraulic push rod body, and an injection tube. The control box and the pipe forming mold are respectively installed on the top of the base body. The hydraulic push rod body is arranged above the pipe forming mold. The output end of the hydraulic push rod body is connected to the injection tube. A support frame is arranged on the outer side of the base body. A guide groove is formed on the surface of the support frame. A forward and reverse motor is installed at the bottom of the support frame. The output end of the forward and reverse motor is connected to a rotating disk. A guide column is connected to the bottom of the rotating disk near the guide groove. A first pneumatic push rod is installed on the surface of the rotating disk. A support plate is connected to the output end of the first pneumatic push rod. A second pneumatic push rod is installed on the surface of the support plate. A connecting block is connected to the output end of the second pneumatic push rod. A forward and reverse motor is installed at the front of the connecting block. The output end of the forward and reverse motor is connected to a bidirectional lead screw through a coupling. A moving block is threaded to the outer side of the bidirectional lead screw. Clamping blocks are connected to the ends of the two moving blocks.

[0006] Preferably, the guide column and the support frame form a rotary sliding structure through the guide groove.

[0007] Preferably, the inner wall of the clamping block is arc-shaped.

[0008] Preferably, a connecting seat is connected to the outside of the injection tube, a spring is connected inside the connecting seat, and a locking block is connected to one end of the spring.

[0009] Preferably, the bottom of the connecting seat is provided with a protective cylinder, and a buffer washer is connected to the bottom of the protective cylinder.

[0010] Preferably, a connecting plate is connected to the outer side of the protective cylinder, and a plug-in block is inserted through the inside of the connecting plate.

[0011] Preferably, the connector has a groove inside that matches the size of the plug block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the second pneumatic push rod is running, its end can extend and drive the connecting block to move to the outside of the pipe forming mold. When the forward and reverse motors are started and rotated in the forward direction, they can drive the two sets of moving blocks to slide closer to each other in a threaded manner. When the injection tube is connected to the top of the pipe forming mold, the buffer gasket at the bottom of the protective cylinder will be deformed by the pressure of the machine base body. When the injection tube is injecting and separating from the pipe forming mold, the protective cylinder can prevent water on the pipe forming mold from splashing onto the equipment and personnel, making the equipment less susceptible to contamination and personnel less likely to get wet.

[0013] 1. A hydraulic expansion machine can expand pipes of a specified diameter to meet production or processing needs. During operation, manual unloading poses a safety risk. When the second pneumatic push rod is in operation, its end extends and moves the connecting block to the outside of the pipe forming mold. When the forward and reverse motors are started, their forward rotation drives two sets of moving blocks to slide closer together. When both sets of clamping blocks have moved to the outside of the pipe, they clamp and fix the pipe. At this point, the first pneumatic push rod can be activated. When the first pneumatic push rod is in operation, its end moves the support plate and the second pneumatic push rod upwards, thereby... The moving clamping block and the pipe move upwards. When the pipe is completely removed from the pipe forming mold, the second pneumatic push rod retracts. When the forward and reverse motors rotate forward, they can drive the rotating disk to rotate. While the rotating disk is rotating, it can drive the first pneumatic push rod and the pipe to move forward. When the pipe moves to the designated position, the forward and reverse motors can be reversed, so that the two sets of clamping blocks no longer clamp the pipe, thus completing the unloading. During unloading, a collection box (not shown in the diagram) can be placed below the pipe unloading point to collect the processed pipe. The above method can complete the automatic unloading operation of the pipe, thus eliminating the need for manual unloading and improving the safety of the unloading operation.

[0014] 2. During the use of the hydraulic water expansion machine, water splashes from the pipe forming mold, potentially splashing onto equipment and personnel. A protective sleeve can be attached to the outside of the injection tube. When the top of the protective sleeve moves to the bottom surface of the connecting seat, the insertion block can be pushed towards the connecting seat. The end of the insertion block will press against the inclined surface of the locking block. When the spring is compressed to its maximum extent, the end of the insertion block can move to the deepest part of the connecting seat. At this point, the locking block can be reset by the spring, allowing the end of the locking block to engage with the insertion block. When the injection tube connects with the top of the pipe forming mold, the buffer gasket at the bottom of the protective sleeve will deform under the pressure of the machine base. During injection and separation from the pipe forming mold, the protective sleeve prevents water from splashing onto the equipment and personnel, thus protecting the equipment from contamination and preventing personnel from getting wet.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-Figure 4 It is understood that this utility model provides a technical solution: a hydraulic expansion machine with an automatic unloading structure, comprising: a base body 1, a control box 2, a pipe forming mold 3, a hydraulic push rod body 4, and an injection tube 5. The control box 2 and the pipe forming mold 3 are respectively installed on the top of the base body 1. The hydraulic push rod body 4 is arranged above the pipe forming mold 3. The output end of the hydraulic push rod body 4 is connected to the injection tube 5. A support frame 6 is arranged on the outer side of the base body 1. A guide groove 7 is opened on the surface of the support frame 6. A forward and reverse motor 8 is installed at the bottom of the support frame 6. The output end of the forward and reverse motor 8 is connected to a rotating disk 9. The rotating disk 9 is close to the bottom of the guide groove 7. A guide post 10 is connected to the rotating disk 9. A first pneumatic push rod 11 is mounted on the surface of the rotating disk 9. The output end of the first pneumatic push rod 11 is connected to a support plate 12. A second pneumatic push rod 13 is mounted on the surface of the support plate 12. A connecting block 14 is connected to the output end of the second pneumatic push rod 13. A forward and reverse motor 15 is mounted on the front of the connecting block 14. The output end of the forward and reverse motor 15 is connected to a bidirectional lead screw 16 via a coupling. A moving block 17 is threaded onto the outer side of the bidirectional lead screw 16. A clamping block 18 is connected to the end of each of the two moving blocks 17. A rotating sliding structure is formed between the guide post 10 and the support frame 6 via a guide groove 7. The inner wall of the clamping block 18 is arc-shaped.

[0023] In practice, the hydraulic expansion machine can expand pipes of a specified diameter to meet production or processing needs. However, manual unloading during operation poses a safety risk. After expansion, the injection tube 5 can rise to a specified height by retracting the hydraulic push rod body 4. At this point, the pipe is inside the pipe forming mold 3, with a portion protruding. The second pneumatic push rod 13 can then be activated. When the second pneumatic push rod 13 is running, its end extends and moves the connecting block 14 to the outside of the pipe forming mold 3. When the forward and reverse motors 15 are activated, their forward rotation drives two sets of moving blocks 17 to slide closer together. As the moving blocks 17 move, they also move the clamping block 18. When both sets of clamping blocks 18 move to the outside of the pipe fitting, the two sets of clamping blocks 18 can clamp and fix the pipe fitting. At this time, the first pneumatic push rod 11 can be activated. When the first pneumatic push rod 11 runs, its end can drive the support plate 12 and the second pneumatic push rod 13 to move upward, thereby driving the clamping blocks 18 and the pipe fitting to move upward. When the pipe fitting is completely removed from the inside of the pipe fitting forming mold 3, the second pneumatic push rod 13 is retracted, so that the pipe fitting can move above the support frame 6. Then the forward and reverse motor 8 is activated. When the forward and reverse motor 8 rotates forward, it can drive the rotating disk 9 to rotate. When the rotating disk 9 rotates, it can drive the guide column 10 to rotate and slide along the guide groove 7. While the rotating disk 9 is rotating, it can drive the first pneumatic push rod 11 and the pipe fitting to move forward.

[0024] See Figure 1-Figure 4 As can be seen, when the pipe is moved to the designated position, the forward and reverse motors 15 can be reversed, so that the two sets of clamping blocks 18 no longer clamp the pipe, thereby completing the unloading. During unloading, a collection box (not shown in the figure) can be placed below the pipe unloading to collect the processed pipe. The above method can complete the automatic unloading operation of the pipe, thereby eliminating the need for manual unloading and improving the safety of the unloading operation.

[0025] See Figure 1 and Figure 5 It can be seen that the outside of the injection tube 5 is connected to the connecting seat 19, the inside of the connecting seat 19 is connected to the spring 20, one end of the spring 20 is connected to the locking block 21, the bottom of the connecting seat 19 is provided with the protective cylinder 22, the bottom of the protective cylinder 22 is connected to the buffer washer 23, the outside of the protective cylinder 22 is connected to the connecting plate 24, the inside of the connecting plate 24 is inserted through the insertion block 25, the inside of the connecting seat 19 is provided with a sliding groove that matches the size of the insertion block 25, and the inner diameter of the buffer washer 23 and the protective cylinder 22 are the same.

[0026] In practice, during the use of the hydraulic water expansion machine, water can be injected into the pipe through the injection tube 5. After the pipe is injected, the injection tube 5 will rise. During the water injection process and when the injection tube 5 just separates from the pipe forming mold 3, water on the pipe forming mold 3 splashes in all directions, which can easily cause equipment and personnel to be splashed by water. The protective cylinder 22 can be sleeved on the outside of the injection tube 5. When the top of the protective cylinder 22 moves to the bottom surface of the connecting seat 19, the plug block 25 can be pushed towards the connecting seat 19. When the end of the plug block 25 moves into the connecting seat 19, the end of the plug block 25 will squeeze the inclined surface of the locking block 21. When the locking block 21 is squeezed, it will compress the spring 20. When the spring 20 is compressed to the maximum extent, the end of the plug block 25 can move to the deepest part of the connecting seat 19. At this time, the locking block 21 can be reset by the spring 20, so that the end of the locking block 21 can engage with the plug block 25, thereby installing the protective cylinder 22 on the outside of the injection tube 5.

[0027] See Figure 1 and Figure 5 It is known that when the injection tube 5 is connected to the top of the pipe forming mold 3, the buffer gasket 23 at the bottom of the protective cylinder 22 will be deformed by the pressure of the machine base body 1. When the injection tube 5 is injecting and separating from the pipe forming mold 3, the protective cylinder 22 can prevent water on the pipe forming mold 3 from splashing onto the equipment and personnel, making the equipment less susceptible to contamination and personnel less likely to get wet.

[0028] In summary, when using this hydraulic expansion machine with an automatic unloading structure, the end of the second pneumatic push rod 13 can extend and drive the connecting block 14 to move to the outside of the pipe forming mold 3. When the forward and reverse motors 15 are started, the forward and reverse motors 15 can drive the two sets of moving blocks 17 to slide closer to each other in a threaded manner. When the pipe moves to the designated position, the forward and reverse motors 15 can be reversed, so that the two sets of clamping blocks 18 no longer clamp the pipe, thereby completing the unloading. During unloading, a collection box (not shown in the figure) can be placed below the pipe unloading point to collect the processed pipe. The above methods can be used to automatically unload pipe fittings, thus eliminating the need for manual unloading and improving the safety of the unloading operation. When the injection tube 5 is connected to the top of the pipe fitting forming mold 3, the buffer gasket 23 at the bottom of the protective cylinder 22 will be deformed by the pressure of the machine base body 1. When the injection tube 5 is injecting and separating from the pipe fitting forming mold 3, the protective cylinder 22 can prevent water on the pipe fitting forming mold 3 from splashing onto the equipment and personnel, making the equipment less susceptible to contamination and personnel less likely to get wet. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
