Description

Technical Field

[0001] The utility model relates to the field of hydraulic pipe production, in particular to a joint pressing device. Background Art

[0002] Hydraulic hose is also known as hydraulic oil hose, hydraulic hose, high-pressure hose, hydraulic pipe, steel wire high-pressure hose, steel wire braided hose and steel wire spiral hose. It is generally divided into steel wire braided hydraulic hose and steel wire spiral hydraulic hose. The hydraulic hose is mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, 2 or 4 or 6 layers of steel wire spiral reinforcement layer and an outer rubber layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion. The outer rubber layer protects the steel wire from damage. The steel wire layer is a skeleton material that plays a reinforcing role.

[0003] When producing hydraulic pipes, it is necessary to first install a joint at one end of the hydraulic pipe, and then extend the hydraulic pipe with the joint and the outer sleeve installed into the crimping device. The end of the hydraulic pipe is crimped to the joint through the outer sleeve by squeezing the crimping device. During this process, the operator needs to manually adjust the crimping position of the hydraulic pipe, and the operator needs to manually support the other end of the hydraulic pipe during crimping. After crimping, the next hydraulic pipe joint and outer sleeve need to be installed. This is very inconvenient and also affects the installation of the next hydraulic pipe, which easily reduces the production speed of the hydraulic pipe. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-9 As shown, a joint crimping device includes a crimping mechanism 1 for fixing a joint on a hydraulic hose. The crimping mechanism 1 is located inside a lower pressing frame 5. An upper pressing frame 4 is fixed to the upper side of the crimping mechanism 1. The device also includes a positioning mechanism 2 and a supporting mechanism 3 for adjusting the crimping position of the hydraulic hose.

[0034] In this embodiment: the buckling mechanism 1 includes an upper buckling frame 12, a lower buckling frame 16 is provided on the lower side of the upper buckling frame 12, eight annular buckling seats 13 and two bidirectional hydraulic rods 11 are provided between the upper buckling frame 12 and the lower buckling frame 16, the two bidirectional hydraulic rods 11 are respectively located on both sides of the eight buckling seats 13, and the middle position of the bidirectional hydraulic rod 11 is fixed to the inner two sides of the lower pressing frame 5, and the front and rear sides of each buckling seat 13 are slidably connected to a guide frame 14, and the guide frame 14 extends into one end of the buckling seat 13 and is fixed. There are two reset springs 15, one end of the guide frame 14 extending out of the buckle pressing seat 13 is an L-shaped structure, and the end of the guide frame 14 extending into the buckle pressing seat 13 is a T-shaped structure. The buckle pressing seat 13 is located at the guide frame 14L-shaped structure and has a guide port. The buckle pressing seat 13 is located at the guide frame 14T-shaped structure and has a guide groove. The two reset springs 15 are respectively located on both sides of the guide frame 14T-shaped structure, and the end of the reset spring 15 away from the guide frame 14T-shaped structure is fixed to the top of the guide groove of the buckle pressing seat 13, and the upper pressure frame 4 is inside. The top side is fixed with a connecting block for connecting the upper buckle frame 12, and the upper end of the lower buckle frame 5 is slidably connected to the inside of the lower buckle frame 5. The upper buckle frame 12 and the lower buckle frame 16 are concave structures near the buckle seat 13, and the two sides of the concave structure are arc edges. The upper end of the L-shaped structure of the guide frame 14 is fixed on the inner wall of the lower buckle frame 5, and the two bidirectional hydraulic rods 11 telescopic parts are used to drive the upper buckle frame 12 and the lower buckle frame 16 to move closer to the middle position at the same time, and then the eight buckle frames 12 and 16 are adjusted by the concave structures of the upper buckle frame 12 and the lower buckle frame 16. The pressing seats 13 gather towards the center position at the same time, and then the joints of the hydraulic pipes are pressed and fixed by the eight pressing seats 13. At the same time, when the eight pressing seats 13 move towards the middle position, the reset spring 15 of the T-shaped structure of the guide frame 14 is compressed. At the same time, after the eight pressing seats 13 finish pressing the hydraulic pipe joints, the elastic force of the reset spring 15 is used to move the eight pressing seats 13 away from each other along their respective guide frames 14, and at the same time, the downward movement of the upper pressing frame 12 is used to drive the upper pressing frame 4 to move downward along the upper end of the lower pressing frame 5.

[0035] In this embodiment, the positioning mechanism 2 includes a positioning seat 21, which is fixed to one side of the upper pressure frame 4. A slide groove 22 is provided on the positioning seat 21. A positioning plate 23 is provided in the middle of the positioning seat 21. A conical magnetic head 24 for sucking the hydraulic pipe joint is fixed at the lower end of the positioning plate 23. A limiting frame 25 is provided on the lower side of the positioning plate 23. A circular slide rod 231 for sliding in the slide groove 22 is fixed to the upper end of the positioning plate 23. A square slide rod 23 is fixed to the lower side of the positioning plate 23 near the conical magnetic head 24. 32, the square slide bar 232 is slidably connected to the limit frame 25, and the upper pressure frame 4 is used to drive the positioning seat 21 to move downward. At the same time, with the support of the square slide bar 232 by the limit frame 25, the circular slide bar 231 at the upper end of the positioning plate 23 slides in the slide groove 22 of the positioning seat 21. As the circular slide bar 231 slides, the entire positioning plate 23 is moved toward the direction of the buckling seat 13, and then the conical magnetic head 24 of the positioning plate 23 pushes the joint of the hydraulic pipe to the position where it needs to be buckled.

[0036] In this embodiment: the support mechanism 3 includes a support frame 31, the support frame 31 is fixed on the other side of the lower pressure frame 5, a U-shaped frame 32 is fixed on the upper end of the support frame 31, and five support wheels 33 for supporting the hydraulic pipe are rotatably connected to the lower side of the U-shaped frame 32. The support frame 31 is used to support the U-shaped frame 32, and the support wheels 33 on the U-shaped frame 32 are used to provide rolling support for the hydraulic pipe.

[0037] Working principle: When in use, first put the outer sleeve of the connector on one end of the hydraulic pipe, then insert the end of the connector into the interior of one end of the hydraulic pipe, then put the end of the hydraulic pipe with the outer sleeve and connector installed into the center position of the eight buckling seats 13, then insert the end of the connector into the conical magnetic head 24 of the positioning plate 23, and use the conical magnetic head 24 to suck and fix the connector. Then, place the other end of the hydraulic pipe on the U-shaped frame 32, and use the five support wheels 33 on the lower side of the U-shaped frame 32 to support the hydraulic pipe in a rolling manner;

[0038] Then the telescopic parts of the two bidirectional hydraulic rods 11 simultaneously drive the upper buckle frame 12 and the lower buckle frame 16 to move closer to each other, and then the eight buckle seats 13 are pushed to the center position at the same time through the concave structures of the upper buckle frame 12 and the lower buckle frame 16. In this process, each buckle seat 13 moves to the center position along the guide frame 14, and the reset spring 15 begins to compress. When the upper buckle frame 12 moves downward, it drives the positioning seat 21 to follow it to move, and then the positioning plate 23 does not follow the support of the square slide bar 232. As the positioning seat 21 moves downward, the circular slide bar 231 on the upper end of the positioning plate 23 will slide along the slide groove 22 of the positioning seat 21. At this time, the entire positioning plate 23 will move toward the end close to the buckling seat 13, and the conical magnetic head 24 of the positioning plate 23 will push the hydraulic pipe with the joint installed to the side of the support mechanism 3, and then adjust the position of the hydraulic pipe with the joint and the outer sleeve to the buckling position of the eight buckling seats 13, thereby completing the buckling installation of the entire hydraulic pipe joint;

[0039] When the crimping installation is completed, the telescopic parts of the two bidirectional hydraulic rods 11 extend and drive the upper crimping frame 12 and the lower crimping frame 16 away from each other. At this time, the eight crimping seats 13 are disengaged from the concave structures of the upper crimping frame 12 and the lower crimping frame 16, and the reset spring 15 on the guide frame 14 pushes the crimping seat 13 to reset. Then the eight crimping seats 13 leave the crimping position of the hydraulic pipe joint, and then the crimped hydraulic pipe is taken out, and the above action is repeated to install the joint at the other end of the hydraulic pipe.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
