Description

Technical Field

[0001] The utility model belongs to the technical field of ferrule disassembly, and in particular relates to a simple ferrule quick disassembly tool. Background Art

[0002] Transition joints are usually used to connect the hydraulic pipelines of mechanical presses. When the ferrule inside the transition joint is damaged or has quality problems, it is easy to cause oil leakage or joint collapse of the transition joint, affecting the normal use of the press. Therefore, the ferrule needs to be replaced.

[0003] The ferrule is usually pre-installed on the surface of the steel pipe before the transition joint is installed, and it cannot move axially. Therefore, before removing the damaged or quality-problematic ferrule from the steel pipe, the worker needs to loosen the connecting nut of the transition joint on the steel pipe first, then remove the pipeline as a whole, and then use a wrench to hit the back of the connecting nut of the transition joint. The connecting nut of the transition joint is impacted by the wrench and drives the ferrule to fall off the steel pipe. However, this disassembly method not only requires the entire steel pipe to be removed, which is a lot of work, but also the transition joint nut and ferrule are not controlled during the process of the wrench hitting the connecting nut, which can easily cause the transition joint nut to roll off and be lost, bringing many difficulties to the construction, increasing labor costs, and extremely low work efficiency.

[0007] Furthermore, the push rod is a hexagon socket bolt, the head of the hexagon socket bolt is located at the end of the push rod away from the baffle side, and the guide head is installed at the tail of the hexagon socket bolt.

[0010] Furthermore, the diameter of the large diameter end cylinder is larger than the inner diameter of the steel pipe, and the diameter of the large diameter end cylinder is 1 mm smaller than the outer diameter of the steel pipe, so that the ferrule can be removed from the steel pipe along the large diameter end cylinder and the push rod.

[0011] Furthermore, the small-diameter end cylinder is 0.5 mm smaller than the inner diameter of the steel pipe, so that the small-diameter end cylinder of the guide head can extend into the inner hole of the steel pipe.

[0012] Furthermore, the distance between the two baffles is 1 mm larger than the outer diameter of the steel pipe.

[0013] Furthermore, the number of the fixing nuts is two, and the height of the central axis of the fixing nuts is the same as the height of the central axis of the transition joint nut on the steel pipe, so that the steel pipe does not deviate when subjected to force.

[0030] The transition joint nut 8 and the ferrule 9 on the steel pipe 7 are located between the baffle 2 and the push rod 5, and the end face of the transition joint nut 8 close to the baffle 2 is in contact with the two baffles 2; the push rod 5 pushes the steel pipe to move away from the cushion block 3, so that the transition joint nut 8 and the ferrule 9 are separated from the steel pipe 7.

[0031] In a preferred embodiment of the present invention, the push rod 5 is a hexagon socket bolt, the head of the hexagon socket bolt is located at the end of the push rod 5 away from the baffle 2, and the guide head 6 is installed at the tail of the hexagon socket bolt.

[0032] In actual use, the hexagon socket bolt is convenient for quick operation of the electric wrench; through the hexagon socket bolt, the hexagon socket bolt is moved relative to the fixing nut 4, so that the guide head 6 is in contact with the steel pipe 7.

[0033] In a preferred embodiment of the utility model, the guide head 6 is a convex-shaped cylinder, and the large-diameter end cylinder 6-1 of the guide head 6 is connected to the push rod 5; the large-diameter end face located at the step of the guide head 6 fits with the end face of the steel pipe 7 when the steel pipe 7 is disassembled, and the small-diameter end cylinder 6-2 of the guide head 6 extends into the inner hole of the steel pipe 7.

[0034] The diameter of the large diameter end cylinder 6 - 1 is larger than the inner diameter of the steel pipe 7 , and the diameter of the large diameter end cylinder 6 - 1 is 1 mm smaller than the outer diameter of the steel pipe 7 , so that the ferrule 9 can be removed from the steel pipe 7 along the large diameter end cylinder 6 - 1 and the push rod 5 .

[0035] The small-diameter end column 6 - 2 is 0.5 mm smaller than the inner diameter of the steel pipe 7 , so that the small-diameter end column 6 - 2 of the guide head 6 can extend into the inner hole of the steel pipe 7 .

[0036] In actual use, the small-diameter end column 6-2 is arranged to extend into the steel pipe, and the large-diameter end column 6-1 is fitted with the end surface of the steel pipe 7 to prevent the push rod 5 from being separated from the steel pipe 7 during use, thereby ensuring that the ferrule 9 pre-installed on the outer surface of the steel pipe 7 can be smoothly disassembled; the diameter of the large-diameter end column 6-1 is larger than the inner diameter of the steel pipe, and the diameter of the small-diameter end column 6-2 is 1mm smaller than the outer diameter of the steel pipe, so that the push rod 5 will not push the ferrule 9 while pushing the steel pipe 7, and will not affect the disassembly of the ferrule 9.

[0037] In a preferred embodiment of the present invention, the center line of the cushion block 3 coincides with the center line of the bottom plate 1 in the length direction.

[0038] The center line of the guide head 6 coincides with the center line of the push rod 5 .

The center height of the fixing nuts 4 is the same as the center height of the transition joint nut on the steel pipe 7, which ensures that the center lines of the push rod 5 and the steel pipe 7 always coincide, preventing the steel pipe 7 from shifting when subjected to force and affecting disassembly.

[0042] In a preferred embodiment of the present invention, the distance between the two baffles 2 is 1 mm larger than the outer diameter of the steel pipe 7 .

[0043] In actual use, the two baffles 2 are welded on the bottom plate 1 , and the distance between the two baffles 2 is 1 mm larger than the outer diameter of the steel pipe 7 , so that the steel pipe 7 can be flexibly placed therein.

[0044] Working principle of a simple ferrule quick disassembly tool:

[0045] When the tool is in use, first adjust the distance between the push rod 5 and the baffle 2 to the maximum, push the transition joint nut 8 to the front end of the steel pipe 7 and then put it between the push rod 5 and the baffle 2, and put the steel pipe 7 between the two baffles 2; slowly rotate the push rod 5 to move the push rod 5 relative to the fixed nut 4, so that the small-diameter end column 6-2 of the guide head 6 extends into the interior of the steel pipe 7, and the large-diameter end column 6-1 fits with the end surface of the steel pipe 7;

[0046] Fine-tune the overall position of the steel pipe 7 and the transition joint nut 8 so that the rear end face of the transition joint nut 8 fits with the front sides of the two baffles 2 (the movement range of the steel pipe 7 and the transition joint nut 8 is small during the fine-tuning process, and the small-diameter end column 6-2 is always inside the steel pipe 7), and confirm that the center lines of the steel pipe 7 and the push rod 5 coincide; slowly rotate the push rod 5 so that the push rod 5 drives the steel pipe 7 to move away from the cushion block 3, so that the transition joint nut 8 drives the ferrule 9 to slowly separate from the steel pipe 7, and the disassembly of the ferrule 9 is completed. After separation, the transition joint nut 8 and the ferrule 9 will be mounted on the push rod 5, and are not easy to lose.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
