Description

Technical Field

[0001] The present invention belongs to the technical field of internal high-pressure presses, and more specifically, relates to an internal high-pressure press with high sealing performance. Background Art

[0002] An internal high-pressure press injects high-pressure liquid (usually emulsion) into the interior of a pipe, and simultaneously applies an axial pressure to the outside of the pipe, causing the pipe to undergo plastic deformation within a mold and conform to the mold cavity, thereby obtaining various complex-shaped hollow components. Throughout this process, the internal high pressure is the main power source for promoting the deformation of the pipe, while the external axial force plays an auxiliary and deformation-control role.

[0003] When the existing internal high-pressure press injects and shapes a pipe, the two ends of the pipe will retract during deformation, which easily leads to a decrease in the contact pressure between the water injection port and the pipe, and further easily leads to a decrease in the sealing effect between the pipe and the water injection port, resulting in pressure relief and affecting the shaping effect of the pipe.

[0004] To solve the above problems, a high-sealing internal high-pressure press is proposed in this application. Summary of the Invention

[0005] In view of the problems in the related art, the present invention provides a high-sealing internal high-pressure press to overcome the above technical problems existing in the related art.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A high-sealing internal high-pressure press includes a base, on the top of which four symmetrically arranged support rods are fixedly installed. The tops of the four support rods are fixedly installed with the same top plate. On the top of the top plate, a hydraulic cylinder is fixedly installed. A push plate is fixedly installed on the piston of the hydraulic cylinder, and the push plate is connected to the four support rods; Two water injection tanks, which are slidably installed on the top of the base. On the mutually remote sides of the two water injection tanks, conduits are installed. On the mutually adjacent sides of the two water injection tanks, fixed pipes are fixedly installed. On each of the two fixed pipes, a water injection cylinder is slidably connected; A lower mold, which is fixedly installed on the top of the base. An installation frame is fixedly installed at the bottom of the push plate. An upper mold is installed at the bottom of the installation frame. The upper mold and the lower mold cooperate with each other, and a material pipe is placed on the lower mold; A water injection mechanism, which is installed in the water injection cylinder and cooperates with the material pipe. On the mutually adjacent ends of the two water injection cylinders, placement holes are opened, and the material pipe is located in the two placement holes; A sealing mechanism, which is installed in the water injection cylinder and cooperates with the material pipe. The sealing mechanism cooperates with the water injection mechanism; The adjusting mechanism is installed on one side of the water injection cylinder and cooperates with the water injection mechanism.

[0007] Preferably, the water injection mechanism includes a wedge-shaped water injection pipe. An installation plate is slidably connected to the inner wall of the water injection cylinder. The wedge-shaped water injection pipe is fixedly connected to the installation plate. A connecting pipe is fixedly installed on one side of the installation plate. The connecting pipe is slidably connected to the fixed pipe. The wedge-shaped water injection pipe cooperates with the material pipe. A buffer spring is installed on one side of the installation plate.

[0008] The water in the water injection tank is injected into the connecting pipe through the fixed pipe, then discharged through the wedge-shaped water injection pipe, and water pressure is injected into the material pipe. At the same time, the connecting pipe is slidably connected to the fixed pipe and, under the action of the buffer spring, can push the wedge-shaped water injection pipe, so that the wedge-shaped water injection pipe maintains a sealed contact state with the material pipe.

[0009] Preferably, two symmetrically arranged wedge-shaped push blocks are fixedly installed at the bottom of the push plate. A wedge-shaped top block is fixedly installed at the top of the water injection tank. The wedge-shaped push block cooperates with the wedge-shaped top block.

[0010] The moving push plate cooperates with the wedge-shaped push block and the wedge-shaped top block, so as to be able to push the wedge-shaped top block to move and drive the water injection tank to move.

[0011] Preferably, two symmetrically arranged sliding grooves are formed in the top of the base. A sliding rod is fixedly installed on the inner wall of the sliding groove. A slider is slidably connected to the sliding rod. The slider is fixedly connected to the corresponding water injection tank. And a reset spring is fixedly installed on one side of each of the two sliders close to each other. One end of the reset spring is fixedly connected to the inner wall of the sliding groove.

[0013] Preferably, the sealing mechanism includes an active sealing capsule ring and a driven sealing capsule ring. Two annular placement grooves are formed in the inner wall of the placement hole. The active sealing capsule ring and the driven sealing capsule ring are placed in the annular placement grooves.

[0014] The setting of the active sealing capsule ring and the driven sealing capsule ring can facilitate the double-sealing operation of the water injection cylinder and the material pipe itself, preventing the water pressure in the wedge-shaped water injection pipe from leaking and affecting the forming operation of the material pipe.

[0015] Preferably, two pressing rings are slidably connected to the inner wall of the annular placement groove, and the two pressing rings are respectively located on the sides of the active sealing capsule ring and the driven sealing capsule ring away from each other.

One end of the ejector rod is fixedly installed with a cushion block, and one side of the cushion block is fixedly installed with a support spring, and one end of the support spring is fixedly connected to the water injection cylinder.

[0016] The moving water injection cylinder drives the ejector rod and the cushion block to move. When the cushion block contacts the upper die and the lower die, due to the reaction force of the upper die and the lower die, the ejector rod drives the pressing ring to have a reaction force, and then drives the pressing ring to squeeze the active sealing capsule ring, causing the active sealing capsule ring to deform and being squeezed between the placement hole and the material pipe, so as to be able to seal between the placement hole and the material pipe.

[0017] Preferably, an annular groove is formed on the inner wall of the placement hole. A plurality of support bars are fixedly installed on one side inner wall of the annular groove. A hinge rod is rotatably connected to the support bar.

A plurality of pull rods are fixedly installed on one side of the mounting plate, and the pull rods are rotatably connected to the other ends of the corresponding hinge rods.

[0018] The moving mounting plate drives the hinge rod to change its angle through the pull rod. The hinge rod with the changed angle drives the connecting rod to move in the reverse direction through the rotational connection of the other end with the connecting rod, and the connecting rod drives the corresponding pressing ring to move, so as to be able to press the driven sealing capsule ring, and then be able to cause the driven sealing capsule ring to deform and seal between the placement hole and the material pipe.

[0019] Preferably, fixed shafts are fixedly installed on both the pull rod and the connecting rod. Two symmetrically arranged movable holes are formed on the hinge rod, and the movable holes are movably connected to the corresponding fixed shafts.

[0020] The movable connection between the fixed shaft and the movable hole can buffer the vertical displacement amount when the hinge rod changes its angle, so that the hinge rod can smoothly push the connecting rod to move.

A push ring is slidably connected to the threaded sleeve. A plurality of push rods are fixedly installed on one side of the push ring, and the push rods are fixedly connected to the positioning ring.

[0022] The positioning ring can buffer and support the mounting plate through the buffer spring. At the same time, when the push ring moves, it can push the positioning ring to move through the push rod, and then can adjust the extrusion force of the positioning ring on the buffer spring, so as to adjust the contact force between the wedge-shaped water injection pipe and the material pipe, and squeeze and seal the material pipe under high pressure.

[0023] Preferably, a top ring is threadedly connected to the outside of the threaded sleeve. The top ring is rotatably connected to the push ring, and a plurality of handles are fixedly installed on the top ring.

[0024] Push the handle, and the handle drives the top ring to rotate. The top ring is threadedly connected to the threaded sleeve, so that the top ring can be driven to move, and the top ring pushes the push ring to move.

[0025] In summary, the technical effects and advantages of the present invention are as follows: Through the mutual cooperation of the wedge-shaped push block and the wedge-shaped top block, and the top ring of the positioning ring pushing against the mounting plate through the buffer spring, the downward-moving push plate can drive the water injection cylinder to move, so as to squeeze and seal both ends of the material pipe, thus facilitating the high-pressure water injection of the material pipe by the water injection tank.

[0026] Through the arrangement of the active sealing capsule ring and the driven sealing capsule ring, and when the pressing ring acts on the active sealing capsule ring and the driven sealing capsule ring, the moving pressing ring can press and deform the active sealing capsule ring and the driven sealing capsule ring, so as to seal the space between the placement hole and the material pipe, thereby preventing pressure leakage at both ends of the material pipe and affecting the forming operation of the material pipe.

[0027] Through the threaded connection between the top ring and the threaded sleeve, and the push ring being pushed by the top rod against the positioning ring, the rotating top ring can adjust the position of the positioning ring, so as to adjust the pressing force of the positioning ring on the buffer spring and the mounting plate, and further adjust the contact force between the wedge-shaped water injection pipe and the material pipe, facilitating the adjustment of the injection pressure operation inside the material pipe.

[0035] Refer to Figure 4 , the sealing mechanism 6 includes an active sealing bladder ring 62 and a driven sealing bladder ring 61. Two annular placement grooves 17 are opened on the inner wall of the placement hole 18. The active sealing bladder ring 62 and the driven sealing bladder ring 61 are placed in the annular placement grooves 17.

[0036] Refer to Figure 4, two pressure rings 66 are slidably connected to the inner wall of the annular placement groove 17.

[0039] Refer to Figure 4, the adjusting mechanism 7 includes a threaded sleeve 72 which is fixedly installed on one side of the water injection cylinder 15. A positioning ring 71 is slidably connected to the inner wall of the water injection cylinder 15. One end of the positioning ring 71 is fixedly connected to the buffer spring 56. A push ring 74 is slidably connected to the threaded sleeve 72. A plurality of push rods 75 are fixedly installed on one side of the push ring 74. The push rods 75 are fixedly connected to the positioning ring 71. The positioning ring 71 can buffer and support the mounting plate 54 through the buffer spring 56.

[0040] Referring to Figure 5 , an end ring 73 is threadedly connected to the outside of the threaded sleeve 72. The end ring 73 is rotatably connected to the push ring 74, and a plurality of handles 76 are fixedly installed on the end ring 73.

[0041] Working principle: During operation, place the material tube 19 on the lower die 11. Start the switch of the hydraulic cylinder 8. The piston of the hydraulic cylinder 8 drives the push plate 9 to move downward. The push plate 9 drives the two wedge-shaped push blocks 51 to move downward. The wedge-shaped push blocks 51 cooperate with the wedge-shaped top blocks 52, so as to be able to push the wedge-shaped top blocks 52 to move, and drive the water injection tank 4 to move. The water injection tank 4 drives the fixed tube 14 and the water injection cylinder 15 to move, and places the material tube 19 into the placement hole 18 in the water injection cylinder 15. At the same time, the moving fixed tube 14 presses and positions the two ends of the material tube 19 through the wedge-shaped water injection pipe 55. Under the action of the buffer spring 56, the wedge-shaped water injection pipe 55 can be pushed, so that the wedge-shaped water injection pipe 55 maintains a sealed contact state with the material tube 19. The water in the water injection tank 4 is injected into the connecting pipe 53 through the fixed tube 14, and then discharged through the wedge-shaped water injection pipe 55, and water pressure is injected into the material tube 19. At the same time, the downward moving push plate 9 drives the upper die 12 to press and seal the material tube 19 through the mounting frame 13. When the water injection cylinder 15 moves, the moving water injection cylinder 15 drives the ejector rod 63 and the cushion block 64 to move. When the cushion block 64 contacts the upper die 12 and the lower die 11, through the reaction force of the upper die 12 and the lower die 11, the ejector rod 63 drives the pressure ring 66 to generate a reaction force, and then drives the pressure ring 66 to squeeze the active sealing bladder ring 62, so that the active sealing bladder ring 62 is deformed and squeezed between the placement hole 18 and the material tube 19, so as to be able to seal between the placement hole 18 and the material tube 19. When the water injection cylinder 15 drives the wedge-shaped water injection pipe 55 to squeeze and seal the material tube 19, the material tube 19 will push the wedge-shaped water injection pipe 55 to generate a reaction force, so that a reverse displacement occurs between the water injection cylinder 15, the wedge-shaped water injection pipe 55 and the mounting plate 54. The moving mounting plate 54 drives the articulated rod 692 to change the angle through the pull rod 67. The articulated rod 692 with the changed angle drives the other end to rotate with the connecting rod 68, so as to be able to drive the connecting rod 68 to move in the reverse direction. The connecting rod 68 drives the corresponding pressure ring 66 to move, so as to be able to press the driven sealing bladder ring 61, so that the driven sealing bladder ring 61 is deformed, and seal the operation between the placement hole 18 and the material tube 19, so as to be able to perform a double sealing operation on the material tube 19 to prevent pressure relief between the material tube 19 and the water injection cylinder 15. When it is necessary to adjust the extrusion force between the wedge-shaped water injection pipe 55 and the material tube 19, rotate the handle 76. The handle 76 drives the top ring 73 to rotate. The top ring 73 drives the top ring 73 to move through the threaded connection with the threaded sleeve 72. The top ring 73 pushes the push ring 74 to move. When the push ring 74 moves, it can push the positioning ring 71 to move through the push rod 75, so as to be able to adjust the extrusion force of the positioning ring 71 on the buffer spring 56, so as to adjust the contact force between the wedge-shaped water injection pipe 55 and the material tube 19, and squeeze and seal the material tube 19 under high pressure.
