[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.
[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.
[0027] Embodiment 1
[0028] Referring to Figures 3 to 4 , this is the first embodiment of the present invention. This embodiment provides an oil circuit docking sealing device for a punching machine. The oil circuit docking sealing device of the punching machine includes a sealing assembly 200, which can enhance the sealing effect and reduce the equipment maintenance cost.
[0029] Specifically, the sealing assembly 200 includes a sealing ring 201a and a movable plate 201b. The movable plate 201b is located at the bottom of the sealing ring 201a.
[0030] When the equipment supplies oil, the force when the oil moves upward will cause the movable plate 201b to move upward. At this time, the sealing ring 201a will be lifted and fit against the bottom of the punching machine 101a. At this time, the sealing ring 201a will fit tighter, improving the sealing effect.
[0031] Specifically, a tension spring 201c is provided at the bottom of the movable plate 201b.
[0032] When the movable plate 201b moves upward, the tension spring 201c will be deformed by force, and at the same time ensure the stability of the upward movement of the movable plate 201b. When the equipment stops supplying oil, the restoring elastic force of the tension spring 201c will pull the movable plate 201b downward for resetting.
[0033] Embodiment 2
[0034] Referring to Figure 4 and Figure 5, which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.
[0035] Specifically, four tension springs 201c are provided and are symmetrically fixed to the bottom of the movable plate 201b respectively.
[0036] All four tension springs 201c are arranged at the bottom of the movable plate 201b to improve the stability of the movable plate 201b when moving upward.
[0037] Specifically, a groove 201b-1 is formed on the surface of the movable plate 201b, and a sealing sleeve 201d is provided on the surface of the groove 201b-1.
[0038] The sealing sleeve 201d is arranged inside the groove 201b-1 to increase its sealing performance, improve the sealing effect and prevent oil leakage from causing adverse effects on the equipment.
[0039] Specifically, a chute 201b-2 is formed at the top of the movable plate 201b, and a pushing block 201e is arranged in the chute 201b-2.
[0040] The chute 201b-2 is an inclined plane and is slidably connected to the pushing block 201e. One end of the pushing block 201e is in contact with the sealing ring 201a. When the movable plate 201b moves upward, the chute 201b-2 will move upward accordingly. At this time, the inclined plane of the chute 201b-2 will push the pushing block 201e to move to one side, and the pushing block 201e will slowly push the sealing ring 201a to one side, making it closely fit with the notch 101b-1, further increasing the sealing performance.
[0041] Specifically, a spring 201f is provided on one side of the pushing block 201e.
[0042] When the pushing block 201e is forced to move to one side, the spring 201f will be deformed under force. After the equipment stops supplying oil, the movable plate 201b will move downward to reset. At this time, the force on the pushing block 201e disappears, and the reset elastic force of the spring 201f will move the pushing block 201e in the reverse direction to reset.
[0043] Specifically, a fixed column 202a is fixed inside the movable plate 201b.
[0044] The fixed column 202a will first come into contact with the oil and be pushed to move upward. At this time, it will drive the movable plate 201b to move upward together and squeeze the sealing ring 201a.
[0045] Embodiment 3
[0046] Refer to Figures 1 to 3 , which is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.
[0047] Specifically, it further includes a main body component 100, which is arranged on the surface of the sealing component 200 and includes a punching press 101a and a base 101b. The base 101b is located at the bottom of the punching press 101a.
[0048] After the punching press 101a and the base 101b are combined, the equipment can be started to perform the oil supply start operation.
[0049] Specifically, the base 101b is provided with a notch 101b-1, and the movable plate 201b is arranged on the notch 101b-1.
[0050] Both the sealing ring 201a and the movable plate 201b are arranged inside the notch 101b-1, which is convenient for up and down movement.
[0051] Specifically, the base 101b is provided with a slot 101b-2, and the fixed column 202a is inserted into the slot 101b-2 in a plug-in connection.
[0052] The fixed column 202a is inserted inside the slot 101b-2. When the equipment supplies oil, the fixed column 202a will be stressed and move upward through the slot 101b-2, thereby driving the movable plate 201b to move upward to squeeze the sealing ring 201a.
[0053] During use, after the punching press 101a and the base 101b are combined, the equipment can be started to perform the oil supply start operation. At this time, the oil will move upward through the slot 101b-2 and push the fixed column 202a to move upward. Then, the fixed column 202a will drive the movable plate 201b to move upward together. When the movable plate 201b moves upward, the chute 201b-2 will move upward accordingly. At this time, the inclined surface of the chute 201b-2 will push the push block 201e to move to one side. The push block 201e will then slowly push the sealing ring 201a to one side, making it fit tightly with the notch 101b-1. When the push block 201e is stressed and moves to one side, the spring 201f will be stressed and deformed. Then, when the movable plate 201b continues to move upward, the tension spring 201c will be stressed and deformed, while ensuring the stability of the upward movement of the movable plate 201b. When the movable plate 201b moves upward, it will lift the sealing ring 201a and fit it with the bottom of the punching press 101a. At this time, the sealing ring 201a will fit more tightly, improving the sealing effect.
[0054] When the equipment stops supplying oil, the reset elastic force of the tension spring 201c will pull the movable plate 201b downward for reset. At the same time, the sealing ring 201a will also move downward accordingly. When the movable plate 201b continues to move downward for reset, the force on the push block 201e disappears, and the reset elastic force of the spring 201f will move the push block 201e in the reverse direction for reset, releasing the extrusion on the sealing ring 201a.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
