Description

Technical Field

[0001] The utility model relates to the technical field of hydroexpansion machines, in particular to a hydraulic device for a hydroexpansion machine. Background Technique

[0002] For the forming of traditional tubular, cup, shell and other parts, rubber, paraffin wax, etc. are generally used for bulging. Especially for thin copper tubes, lead is used for bulging. After bulging, the forming medium in the cavity needs to be removed. This not only has low working efficiency, but also has high costs for rubber, paraffin wax, lead, etc., and is prone to cause relatively large pollution. Especially, lead is very harmful to the environment. Now many countries have explicitly prohibited the use of lead as a bulging medium. Therefore, a hydroexpansion machine is a commonly used device for the forming of tubular structures.

[0003] When using the hydraulic device of a hydroexpansion machine to form tubular parts, it is necessary to place the tubular parts on the mold to restrict the movement of the tubular parts and avoid position deviation during the extrusion of the tubular parts. Due to the differences in the diameter sizes of different tubular parts, and the size of the mold groove is fixed, when processing different tubular parts, it is necessary to disassemble and replace the mold, which will affect the processing progress of the tubular parts.

It further includes:

[0006] An adjusting component, which is arranged on the mold and is used to adapt to tubular parts of different sizes;

[0007] Among them, the adjusting component includes a first notch, the first notch is opened at the top of the mold, a fixed rod is installed inside the first notch, a movable plate is sleeved on the outer surface of the fixed rod, an adjusting piece is installed on one side of the movable plate, a cavity is opened inside the mold, the movable plate is divided into two groups, connecting frames are installed at the bottoms of the two groups of movable plates respectively, a rotating shaft is sleeved inside the cavity, a first gear is installed on the outer surface of the rotating shaft, a second gear is installed at one end of the rotating shaft, a second notch is opened inside the mold, and a fixed shaft is installed inside the second notch. A movable frame and a return spring are sleeved on the outer surface of the fixed shaft.

[0008] In the above, the end of the adjusting piece is arc-shaped and bonded with rubber, and the adjusting piece is in extrusion contact with the tubular part.

[0009] As described above, one side of the connecting frame is tooth-shaped, and the connecting frame is meshed and connected with the first gear.

[0010] As described above, the return spring is elastically supported between the second notch and the movable frame.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, the present invention provides a technical solution for a hydro-expansion machine hydraulic device: A hydro-expansion machine hydraulic device includes the main body 1 of the hydro-expansion machine hydraulic device. A hydraulic cylinder 2 is provided on the main body 1 of the hydro-expansion machine hydraulic device. A mold 3 is installed at the end of the hydraulic cylinder 2. It further includes:

[0024] An adjusting assembly, which is arranged on the mold 3 and is used to adapt to tubular parts of different sizes;

[0025] Among them, the adjusting assembly includes a first notch 4. The first notch 4 is opened at the top of the mold 3. A fixed rod 5 is installed inside the first notch 4. A movable plate 6 is sleeved on the outer surface of the fixed rod 5. An adjusting member 7 is installed on one side of the movable plate 6. A cavity 8 is opened inside the mold 3. The movable plate 6 is divided into two groups. Connecting frames 9 are installed at the bottoms of the two groups of movable plates 6 respectively. A rotating shaft 10 is sleeved inside the cavity 8. A first gear 11 is installed on the outer surface of the rotating shaft 10. A second gear 12 is installed at one end of the rotating shaft 10. A second notch 13 is opened inside the mold 3. A fixed shaft 14 is installed inside the second notch 13. A movable frame 15 and a return spring 16 are sleeved on the outer surface of the fixed shaft 14.

[0026] Through the cooperation between the rotating shaft 10 and the cavity 8, the first gear 11 can be driven to rotate. At this time, through the cooperation between the first gear 11 and the connecting frame 9, the two movable plates 6 will be driven to move along the outer surface of the fixed rod 5 through the connecting frame 9, so that the tubular part can be extruded by the adjusting member 7. At the same time, due to the elastic force of the return spring 16, the movable frame 15 will be driven to move along the outer surface of the fixed shaft 14. At this time, through the cooperation between the movable frame 15 and the second gear 12, the first gear 11 will be limited by the rotating shaft 10, which is convenient for clamping the tubular part by the adjusting member 7, so that tubular parts of different sizes can be placed.

[0027] AsFigure 2 As shown, the end of the adjusting member 7 is arc-shaped and bonded with rubber, and the adjusting member 7 is in extrusion contact with the tubular part.

[0028] Through the rubber provided at the end of the adjusting member 7, when it extrudes the tubular part, it can be closely attached to the tubular part and prevent abrasion of the surface of the tubular part.

[0029] As Figure 3 shown, one side of the connecting frame 9 is tooth-shaped, and the connecting frame 9 is meshed and connected with the first gear 11.

[0030] Through the cooperation between the connecting frame 9 and the first gear 11, when the first gear 11 rotates, it will drive the two connecting frames 9 to move towards each other, so that the adjusting member 7 can be driven by the movable plate 6 to extrude the tubular part, and when the tubular part is extruded, the position deviation of the tubular part can be avoided.

[0031] As Figure 5 shown, the return spring 16 is elastically supported between the second notch 13 and the movable frame 15.

[0032] Through the design of the return spring 16, the movable frame 15 has good elastic reset performance. At this time, since the return spring 16 is in a compressed state, a elastic force will be applied to the movable frame 15, so that the rotation shaft 10 and the first gear 11 can be positioned through the cooperation between the movable frame 15 and the second gear 12.

[0033] As Figure 5 shown, the top of the movable frame 15 is tooth-shaped, and the movable frame 15 is movably clamped with the second gear 12.

[0034] Through the design of the movable frame 15, since the movable frame 15 is tooth-shaped, when the return spring 16 pushes the movable frame 15 to move, the second gear 12 will be positioned through the cooperation between the movable frame 15 and the second gear 12.

[0035] As Figure 5 shown, when the movable frame 15 moves along the outer surface of the fixed shaft 14, it can be separated from the second gear 12.

[0036] Through the cooperation between the movable frame 15 and the fixed shaft 14, the movable frame 15 can move along the outer surface of the fixed shaft 14, so that the movable frame 15 can be separated from the second gear 12, and the limit on the rotation shaft 10 can be released, and then the rotation shaft 10 can be rotated to drive the first gear 11 to rotate, which is convenient to drive the connecting frame 9 to move.

[0037] Working principle:

[0038] First, the staff places the tubular part on the mold 3, then presses to separate the movable frame 15 from the second gear 12 and rotates the second gear 12. At this time, through the cooperation between the rotating shaft 10 and the cavity 8, the first gear 11 can be driven to rotate. At the same time, through the cooperation between the first gear 11 and the connecting frame 9, the two movable plates 6 will be driven to move along the outer surface of the fixed rod 5 through the connecting frame 9, so that the tubular part can be extruded by the adjusting part 7. At the same time, due to the elastic force of the return spring 16, the movable frame 15 will be driven to move along the outer surface of the fixed shaft 14. At this time, through the cooperation between the movable frame 15 and the second gear 12, the first gear 11 will be limited by the rotating shaft 10, which is convenient for clamping the tubular part by the adjusting part 7, so that it can adapt to tubular parts of different sizes.
