Description

Technical Field

[0001] This utility model is a pressurizing device for pressing sealing components, belonging to the field of sealing component pressing. Background Technology

[0002] Rubber gaskets, polytetrafluoroethylene (PTFE), and other materials are common sealing components. Gaskets installed between pipes are annular in shape. Therefore, the raw material for these gaskets needs to be cut using a hydraulic cylinder-driven cutter to form an annular structure. The oil inlet connector on the hydraulic cylinder needs to be connected to an oil supply line. When the hydraulic cylinder-driven cutter compresses the gasket material, the cylinder is under reaction force. At this time, the connection between the oil inlet connector and the oil supply line will vibrate due to the work done, increasing the probability of the oil supply line detaching from the oil inlet connector, resulting in insufficient reliability. Therefore, a pressurizing device is needed to prevent the connection between the oil inlet connector and the oil supply line from detaching during the hydraulic cylinder's operation, thus preventing the sealing component from being compressed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressurizing device for sealing to solve the problems mentioned in the background art. This utility model prevents the oil inlet pipe joint from separating from the oil supply pipeline during the operation of the hydraulic cylinder, thereby improving reliability.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a pressurizing device for sealing element compression includes a base, a crossbeam provided directly above the base, brackets installed at both ends of the crossbeam, the lower ends of the brackets connected to the base, a vertically arranged hydraulic cylinder installed at the middle of the upper surface of the crossbeam, a cylindrical cutter installed at the movable end of the hydraulic cylinder, a vertically arranged guide post installed at the middle of the upper surface of the cylindrical cutter, a guide sleeve installed on the crossbeam, the upper end of the guide post penetrating the guide sleeve and extending to the upper side of the crossbeam, an oil inlet pipe joint installed at the top of the hydraulic cylinder, and a clamping member for clamping the oil inlet pipe joint installed on the upper surface of the crossbeam.

[0005] Furthermore, the clamping component includes a support plate, which is mounted on one side of the upper surface of the crossbeam. The support plate has a Z-shaped structure, and a vertical cylinder is mounted on the upper surface of the support plate. The upper end of the vertical cylinder is open, and a first piston is slidably mounted inside the vertical cylinder. A vertically arranged guide hole is provided on the upper surface of the support plate. A U-shaped rod is mounted on the upper surface of the first piston. The end of the U-shaped rod away from the first piston passes through the guide hole. The outer surface of the end of the U-shaped rod away from the first piston is machined with external threads. Two horizontal plates are fitted onto the threaded end of the U-shaped rod. Two nuts are provided on the upper and lower sides of the horizontal plates to limit the relative position of the horizontal plates and the U-shaped rod. The guide post has... The end is equipped with a movable plate for placement between two horizontal plates. Two symmetrically arranged horizontal cylinders are provided on the outside of the oil inlet pipe joint. The end of the horizontal cylinder opposite to the oil inlet pipe joint is open. A detachable cylinder cover is installed at the open end of the horizontal cylinder. A connecting pipe communicating with the lower end of the horizontal cylinder and the vertical cylinder is installed between the two cylinder covers. A rectangular opening is opened in the middle of the side of the horizontal cylinder opposite to the cylinder cover. A rectangular rod is inserted into the rectangular opening. A second piston is installed at the end of the rectangular rod inside the horizontal cylinder. The second piston is slidably installed inside the horizontal cylinder. A pressure plate is installed at the end of the rectangular rod outside the horizontal cylinder. A detachable soft rubber block is installed on the side of the pressure plate opposite to the rectangular rod.

[0006] Furthermore, a connecting plate is fitted onto the cross cylinder and fixed to the cross cylinder, and one end of the connecting plate is fixed to the support plate.

[0007] Furthermore, the pressure plate has multiple horizontally arranged dovetail grooves on the side facing away from the rectangular rod, and multiple horizontally arranged dovetail strips are connected and fixed on the side of the soft rubber block facing the pressure plate. The dovetail strips and the soft rubber block are integrally formed, and the dovetail strips are inserted into the dovetail grooves.

[0008] Furthermore, the open end of the cross cylinder is fitted with a ring that is fixed to the cross cylinder, and the cylinder cover is connected to the ring by multiple bolts.

[0009] Furthermore, a support ring is installed on the upper surface of the tube cutter, and an intermediate sleeve is provided in the middle of the support ring to be connected and fixed to the tube cutter. Multiple stiffeners are installed in a ring at equal intervals between the intermediate sleeve and the support ring. The stiffeners are connected and fixed to the tube cutter, and the movable end of the hydraulic cylinder is installed in the intermediate sleeve.

[0010] The beneficial effects of this utility model are:

[0011] 1. Place the sealing gasket material on the base, then control the hydraulic cylinder to extend. The hydraulic cylinder drives the cylinder cutter to move downward, so that the cylinder cutter cuts the sealing gasket material on the base, making the sealing gasket material form a ring-shaped structure. During the movement of the cylinder cutter, the guide post and the guide sleeve slide relative to each other, so as to achieve the purpose of guiding and limiting.

[0012] 2. Install a support ring and an intermediate sleeve on the upper surface of the cylinder cutter, and install multiple stiffeners between the support ring and the intermediate sleeve. Thus, during the operation of the hydraulic cylinder, under the action of the support ring, the intermediate sleeve and the multiple stiffeners, the force exerted by the hydraulic cylinder on the cylinder cutter is distributed over the entire upper end of the cylinder cutter, preventing any one part of the cylinder cutter from bearing the force generated by the hydraulic cylinder.

[0013] 3. Adjust the distance between the two horizontal plates according to the stroke between the soft rubber block and the oil inlet pipe joint, and set the movable plate between the two horizontal plates. Then use the nut to limit the relative position of the horizontal plate and the U-shaped rod. Therefore, when the stroke of the hydraulic cylinder is greater than the stroke between the soft rubber block and the oil inlet pipe joint, the movable plate will move a distance between the two horizontal plates and will not make the first piston move synchronously.

[0014] 4. When the hydraulic cylinder extends, the guide column drives the movable plate to move downwards, thereby pressing the lower horizontal plate. This causes the U-shaped rod to drive the first piston to move downwards inside the vertical cylinder. At this time, the air inside the vertical cylinder enters the two horizontal cylinders through the connecting pipe, causing the second piston to drive the pressure plate to move through the rectangular rod. Finally, the two soft rubber blocks are pressed against the surface of the oil inlet pipe joint, which strengthens the connection between the oil inlet pipe joint and the oil supply line, preventing the connection between the oil inlet pipe joint and the oil supply line from disengaging during the operation of the hydraulic cylinder and improving reliability. When the hydraulic cylinder retracts, the first and second pistons return to their original positions. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 This utility model provides a technical solution: a pressurizing device for sealing element compression, including a base 1, a crossbeam 7 directly above the base 1, brackets 8 installed at both ends of the crossbeam 7, the lower ends of the brackets 8 connected to the base 1, a vertically arranged hydraulic cylinder 17 installed at the middle of the upper surface of the crossbeam 7, a cylindrical cutter 2 installed at the movable end of the hydraulic cylinder 17, a vertically arranged guide post 5 installed at the middle of the upper surface of the cylindrical cutter 2, a guide sleeve 6 installed on the crossbeam 7, the upper end of the guide post 5 passing through the guide sleeve 6 and extending to the upper side of the crossbeam 7, a support ring 3 installed on the upper surface of the cylindrical cutter 2, an intermediate sleeve 18 connected and fixed to the cylindrical cutter 2 at the middle of the inner part of the support ring 3, a plurality of ribs 4 installed in a ring at equal intervals between the intermediate sleeve 18 and the support ring 3, the ribs 4 connected and fixed to the cylindrical cutter 2, and the movable end of the hydraulic cylinder 17... The sealing gasket material is placed on the base 1 and installed inside the intermediate sleeve 18. Then, the hydraulic cylinder 17 is extended, and the hydraulic cylinder 17 drives the cylindrical cutter 2 to move downward. The cylindrical cutter 2 cuts the sealing gasket material on the base 1, making the sealing gasket material form a ring structure. During the movement of the cylindrical cutter 2, the guide post 5 and the guide sleeve 6 slide relative to each other to achieve the purpose of guiding and limiting. The support ring 3 and the intermediate sleeve 18 are installed on the upper surface of the cylindrical cutter 2, and multiple stiffeners 4 are installed between the support ring 3 and the intermediate sleeve 18. Then, during the operation of the hydraulic cylinder 17, under the action of the support ring 3, the intermediate sleeve 18 and the multiple stiffeners 4, the force of the hydraulic cylinder 17 on the cylindrical cutter 2 is distributed throughout the entire upper end of the cylindrical cutter 2, preventing any one part of the cylindrical cutter 2 from bearing the force generated by the hydraulic cylinder 17.

[0024] See Figure 1 , Figure 2 and Figure 5The hydraulic cylinder 17 is equipped with an oil inlet pipe connector 15 on its top. A support plate 11 is installed on one side of the upper surface of the crossbeam 7. The support plate 11 has a Z-shaped structure. A vertical cylinder 13 is installed on the upper surface of the support plate 11. The upper end of the vertical cylinder 13 is open. A first piston 19 is slidably installed inside the vertical cylinder 13. A vertically arranged guide hole 28 is opened on the upper surface of the support plate 11. A U-shaped rod 12 is installed on the upper surface of the first piston 19. The end of the U-shaped rod 12 away from the first piston 19 passes through the guide hole 28. The outer surface of the end of the U-shaped rod 12 away from the first piston 19 is machined with external threads. Two horizontal plates 10 are sleeved on the threaded end of the U-shaped rod 12. The upper side of the horizontal plates 10 and the horizontal plates Two nuts 9 are provided on the lower side of each of the two horizontal plates 10 to limit the relative position of the horizontal plate 10 and the U-shaped rod 12. A movable plate 29 is installed on the upper end of the guide column 5 to be set between the two horizontal plates 10. The distance between the two horizontal plates 10 is adjusted according to the stroke between the soft rubber block 22 and the oil inlet pipe joint 15, and the movable plate 29 is set between the two horizontal plates 10. Then, the nuts 9 are used to limit the relative position of the horizontal plate 10 and the U-shaped rod 12. Therefore, when the stroke of the hydraulic cylinder 17 is greater than the stroke between the soft rubber block 22 and the oil inlet pipe joint 15, the movable plate 29 will move a distance between the two horizontal plates 10 and will not cause the first piston 19 to move synchronously.

[0025] See Figures 1-5Two symmetrically arranged horizontal cylinders 16 are provided on the outside of the oil inlet pipe joint 15. The end of the horizontal cylinder 16 facing away from the oil inlet pipe joint 15 is open. A connecting plate 14 is fitted on the horizontal cylinder 16 and fixed to it. One end of the connecting plate 14 is fixed to the support plate 11. A detachable cylinder cover 21 is installed at the open end of the horizontal cylinder 16. A ring is fitted on the open end of the horizontal cylinder 16 and fixed to it. The cylinder cover 21 is connected to the ring by multiple bolts. A connecting pipe 20 communicating with the lower end of the horizontal cylinder 16 and the vertical cylinder 13 is installed between the two cylinder covers 21. A rectangular opening is opened in the middle of the side of the horizontal cylinder 16 facing away from the cylinder cover 21. A rectangular rod 25 is inserted into the rectangular opening. A second piston 24 is installed at the end of the rectangular rod 25 inside the horizontal cylinder 16. The second piston 24 is slidably installed inside the horizontal cylinder 16. The rectangular rod 25 is located on the outside of the horizontal cylinder 16. A pressure plate 23 is installed at one end. A detachable soft rubber block 22 is installed on the side of the pressure plate 23 facing away from the rectangular rod 25. When the hydraulic cylinder 17 extends, the guide column 5 drives the movable plate 29 to move downward, thereby the movable plate 29 presses the horizontal plate 10 on the lower side, causing the U-shaped rod 12 to drive the first piston 19 to move downward in the vertical cylinder 13. At this time, the air in the vertical cylinder 13 enters the two horizontal cylinders 16 through the connecting pipe 20, causing the second piston 24 to move the pressure plate 23 through the rectangular rod 25. Finally, the two soft rubber blocks 22 are pressed against the surface of the oil inlet pipe joint 15, thereby reinforcing the connection between the oil inlet pipe joint 15 and the oil supply line, preventing the connection between the oil inlet pipe joint 15 and the oil supply line from disengaging during the operation of the hydraulic cylinder 17, and improving reliability. When the hydraulic cylinder 17 retracts, the first piston 19 and the second piston 24 return to their original positions.

[0026] See Figure 3 and Figure 4 The pressure plate 23 has multiple horizontally arranged dovetail grooves 27 on the side facing away from the rectangular rod 25. Multiple horizontally arranged dovetail strips 26 are connected and fixed on the side of the soft rubber block 22 facing the pressure plate 23. The dovetail strips 26 and the soft rubber block 22 are integrally formed, so that the dovetail strips 26 are inserted into the dovetail grooves 27, realizing the insertion of the soft rubber block 22 and the pressure plate 23. When the soft rubber block 22 is damaged, the soft rubber block 22 can be replaced separately.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
