[0001] This utility model relates to the field of pipe fitting technology, specifically a pipe fitting crimping device. Background Technology

[0002] Pipe fittings are parts in hydraulic systems that connect pipelines or mount pipelines onto hydraulic components. They are a general term for connectors that can be installed and removed in fluid passages. Before crimping the pipe, the hose needs to be inserted into the core of the metal fitting, so a pipe fitting crimping device is required.

[0003] When operators crimp pipe fittings, they often use corresponding pipe fitting crimping devices. Although the existing devices can achieve the purpose of crimping, they cannot locate pipes and fittings of different sizes to be connected in actual use. Moreover, manual assistance is often required during crimping, which may reduce the efficiency of crimping and reduce its practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe fitting crimping device to solve the problem mentioned in the background art. When operators crimp pipe fittings, they often use corresponding pipe fitting crimping devices. Although the existing devices can achieve the purpose of crimping, they cannot position pipes and pipe fittings of different sizes in actual use. Moreover, manual assistance is often required during crimping, which may reduce the efficiency of crimping and reduce its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe fitting crimping device, comprising a base plate, a fixing block fixedly installed on the top of the base plate, a crimping groove formed on the top of the fixing block, a strip groove formed inside the fixing block, a bidirectional threaded rod rotatably installed inside the strip groove, movable plates threadedly sleeved on both sides of the surface of the bidirectional threaded rod, a positioning plate fixedly installed on the top of each movable plate, a buffer pad fixedly installed on the opposite side of each positioning plate, a support rod fixedly installed at the bottom of the crimping groove, and a support plate fixedly installed on the top of the support rod.

[0006] Preferably, a handle is rotatably mounted on one side of the fixing block, and one side of the handle passes through the fixing block and is fixedly connected to one side of the bidirectional threaded rod.

[0007] Preferably, vertical plates are fixedly installed on both sides of the top of the fixed block, and each vertical plate has a sliding groove inside. A connecting rod is movably installed inside each sliding groove, and a lifting plate is fixedly installed between the connecting rods.

[0008] Preferably, pressure rods are movably installed at both ends of the top of the lifting plate, the bottom of the pressure rods penetrates the lifting plate and extends to the bottom of the lifting plate, a snap-fit ​​plate is fixedly installed at the bottom of the pressure rods, a rubber pad is fixedly installed at the bottom of the snap-fit ​​plate, and a spring is fixedly installed between the snap-fit ​​plate and the lifting plate, and the inner surface of the spring is movably connected to the outer surface of the pressure rod.

[0009] Preferably, a horizontal plate is fixedly installed between the vertical plates, and a pneumatic cylinder is fixedly installed on the top of the horizontal plate, with the output end of the pneumatic cylinder passing through the horizontal plate and fixedly connected to the top of the lifting plate.

[0010] Preferably, guide rods are movably installed on both sides of the top of the horizontal plate, and the bottom of the guide rods penetrates through the horizontal plate and is fixedly connected to the top of the lifting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In daily use, the operator places the pipe and pipe fitting inside the crimping groove and on top of the support plate, and then rotates the handle. The handle then drives the bidirectional threaded rod to rotate, which in turn causes the moving plate to slide inside the strip groove. The moving plate then drives the positioning plate to slide, and the positioning plate then drives the buffer pad to slide until the outer surface of the buffer pad reaches the outer surface of the pipe and pipe fitting. This allows for the positioning of pipes and pipe fittings of different sizes.

[0012] In this type of pipe fitting crimping device, during daily use, the operator activates the pneumatic cylinder. The operation of the pneumatic cylinder pushes the lifting plate to slide, which in turn causes the guide rod to slide inside the horizontal plate. Subsequently, the lifting plate causes the connecting rod to slide inside the groove. When the rubber pad reaches the surface of the pipe and pipe fitting, the rubber pad causes the crimping plate to slide. Then, the crimping plate causes the pressure rod to slide inside the lifting plate, squeezing and compressing the spring. This allows for automatic crimping through the pneumatic cylinder and rubber pad, thereby improving crimping efficiency. Attached Figure Description

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. Example 1:

[0016] Please see Figures 1-5 A pipe fitting crimping device includes a base plate 1, on the top of which a fixing block 2 is fixedly installed. The top of the fixing block 2 has a crimping groove 3. The inside of the fixing block 2 has a strip groove 4. A bidirectional threaded rod 5 is rotatably installed inside the strip groove 4. Movable plates 6 are threadedly sleeved on both sides of the surface of the bidirectional threaded rod 5. Positioning plates 7 are fixedly installed on the top of each movable plate 6. Buffer pads 8 are fixedly installed on the opposite sides of each positioning plate 7. A support rod 9 is fixedly installed at the bottom of the inside of the crimping groove 3. A support plate 10 is fixedly installed on the top of the support rod 9. A handle 11 is rotatably installed on one side of the fixing block 2. One side of the handle 11 passes through the fixing block 2 and is fixedly connected to one side of the bidirectional threaded rod 5.

[0017] In this invention, the connected pipes and fittings can be placed inside the crimping groove 3 and on top of the support plate 10. Then, the handle 11 is rotated, which will drive the bidirectional threaded rod 5 to rotate. At this time, the bidirectional threaded rod 5 will drive the moving plate 6 to slide inside the strip groove 4. Then, the moving plate 6 will drive the positioning plate 7 to slide. Then, the positioning plate 7 will drive the buffer pad 8 to slide until the outer surface of the buffer pad 8 reaches the outer surface of the connected pipes and fittings. This allows for the positioning of connected pipes and fittings of different sizes. Example 2:

[0018] Please see Figures 1-5A pipe fitting clamping device is provided, wherein vertical plates 12 are fixedly installed on both sides of the top of the fixing block 2, and the interior of the vertical plates 12 is provided with sliding grooves 13. Connecting rods 14 are movably installed inside the sliding grooves 13, and lifting plates 15 are fixedly installed between the connecting rods 14. Pressure rods 16 are movably installed at both ends of the top of the lifting plate 15. The bottom of the pressure rods 16 passes through the lifting plate 15 and extends to the bottom of the lifting plate 15. A clamping plate 17 is fixedly installed at the bottom of the pressure rods 16. A rubber pad 18 is fixedly installed at the bottom of the clamping plate 17. A spring 19 is fixedly installed between the clamping plate 17 and the lifting plate 15, and the inner surface of the spring 19 is movably connected to the outer surface of the pressure rod 16.

[0019] In this utility model, when the clamping operation is required, the lifting plate 15 will cause the connecting rod 14 to slide inside the slide groove 13 when it slides. The inner surface of the slide groove 13 and the outer surface of the connecting rod 14 are both smooth, which allows the connecting rod 14 to slide more smoothly inside the slide groove 13. When the rubber pad 18 reaches the surface of the pipe and pipe joint, the rubber pad 18 will cause the clamping plate 17 to slide. Then the clamping plate 17 will cause the pressure rod 16 to slide inside the lifting plate 15 and squeeze and compress the spring 19. Example 3:

[0020] Please see Figures 1-5 A pipe fitting crimping device is provided, wherein a horizontal plate 20 is fixedly installed between vertical plates 12, a pneumatic cylinder 21 is fixedly installed on the top of the horizontal plate 20, and the output end of the pneumatic cylinder 21 passes through the horizontal plate 20 and is fixedly connected to the top of the lifting plate 15. Guide rods 22 are movably installed on both sides of the top of the horizontal plate 20, and the bottom of the guide rods 22 passes through the horizontal plate 20 and is fixedly connected to the top of the lifting plate 15.

[0021] In this invention, when the pneumatic cylinder 21 is running, it pushes the lifting plate 15 to slide. The design of the pneumatic cylinder 21 can improve the adjustment efficiency of the lifting plate 15, thereby improving the clamping efficiency. Subsequently, the lifting plate 15 will drive the guide rod 22 to slide inside the horizontal plate 20. The inner surface of the horizontal plate 20 and the outer surface of the guide rod 22 are both smooth, which can make the guide rod 22 slide more smoothly inside the horizontal plate 20 and reduce the occurrence of jamming. The design of the guide rod 22 can make the sliding of the lifting plate 15 more stable.

[0022] Working principle: First, the operator places the connecting pipe and fitting inside the crimping groove 3 and on top of the support plate 10. Then, the operator rotates the handle 11, which drives the bidirectional threaded rod 5 to rotate. At this time, the bidirectional threaded rod 5 drives the moving plate 6 to slide inside the strip groove 4. Subsequently, the moving plate 6 drives the positioning plate 7 to slide, and then the positioning plate 7 drives the buffer pad 8 to slide until the outer surface of the buffer pad 8 reaches the outer surface of the connecting pipe and fitting. This allows for the positioning of connecting pipes and fittings of different sizes. Then, the operation is started. The operation of the pneumatic cylinder 21 will push the lifting plate 15 to slide, and the lifting plate 15 will drive the guide rod 22 to slide inside the horizontal plate 20. Then the lifting plate 15 will drive the connecting rod 14 to slide inside the slide groove 13. When the rubber pad 18 reaches the surface of the pipe and pipe joint, the rubber pad 18 will drive the clamping plate 17 to slide. Then the clamping plate 17 will drive the pressure rod 16 to slide inside the lifting plate 15 and squeeze and compress the spring 19. The automatic clamping can be achieved by the pneumatic cylinder 21 and the rubber pad 18.
